Subject: Creating bioluminescence with P6 shader nodes?

Nalif opened this issue on Apr 16, 2005 · 223 posts


Nalif posted Sat, 16 April 2005 at 11:48 PM

I have an idea as to how to do this, but I'm not sure how nice it would look. Basically just create your texture map, and then create a black and white mask of the same texture, making the white areas where you want the bioluminescence to be. Then plug the mask into the ambient value node.

That's the most basic thing I can think of, though. The only thing this would really accomplish is the bioluminescence glowing whenever it wasn't under light, though. In normal images, where the figure is somewhat lighted, the other areas wouldn't appear to glow. They would just be slightly brighter than the surrounding parts. (I know, I know. Bioluminescence doesn't really show in the light anyways. I'm not after true bioluminescence. I just want certain areas to appear to glow.) Is there something that would give better results?

And while we're on the topic, P6 is amazing - but I wish they had an option to make an object illuminate other objects around it :( - You can make things glow in the dark, but they don't cast the light on things around them. I want glowing objects >_<

I'm wondering if you would have to do a combination of an object with translucence mapping and a point light positioned inside it. By bioluminescence, I take it you're talking about things like lightning bugs.



Nalif posted Sun, 17 April 2005 at 12:23 AM

Yes - Lightning bugs, jellyfish, anything that lives in deep water, etc.


Little_Dragon posted Sun, 17 April 2005 at 12:46 AM

>> *.... P6 is amazing - but I wish they had an option to make an object illuminate other objects around it :(*

We do have such an option. It's called the gather node, and you can use it to create colour-bleeding effects (simulated radiosity) in the Material Room.

Here's an example, using an ambient material on a simple box prop, and a gather node hooked up to the ground plane.



Nalif posted Sun, 17 April 2005 at 12:57 AM

WHaaaaat? That's amazing. I remember looking into how to hook up the gather node, and for the life of me couldn't get it to work. So does it only "gather" the colors that bleed through the ambient channel? And how do I hook it up? Does it plug into the alternate diffuse?


Little_Dragon posted Sun, 17 April 2005 at 1:21 AM

There are a million different ways to hook it up, of course, but this is the setup with which I've experimented today. Don't forget to enable raytracing in your render options.



Little_Dragon posted Sun, 17 April 2005 at 1:22 AM

Another test render.



xoconostle posted Sun, 17 April 2005 at 1:25 AM

I hadn't tried the gather node before, but Nalif's question intrigued me, so I tried a quickie experiement by plugging the node (with default values) into the alternate diffuse channel of Ajax's floor tile texture on the ground plane. Now I'm looking forward to hours of happy gather node experimentation with other channels and values. Thanks Nalif and Little_Dragon! (Sphere texture is "Bacteria" by Stewer.)

Stonemason: I do a lot of sci-fi modeilng along the lines of your work, and I've always dreamt of a way to make console buttons give off a glow "aura" with a material node. Unforunately, I don't even think this will let us do it. Those buttons always look so flat :(


Little_Dragon posted Sun, 17 April 2005 at 2:45 AM

Actually, I know how you can achieve that, even with the flat-panel controls you see in Star Trek. Place a one-sided square just above above the surface of the control panel, normal-side down. This will be your emitter. Enable "Remove backfacing polys" in your render options. The emitter itself shouldn't be visible when rendered, but the raytraced colour-bleeding still works.

I don't think jelly fish have hooves, either ... but I'll let that slide for now. :)



Nalif posted Sun, 17 April 2005 at 7:05 AM

Messed around for a few more hours and wound up with this. This is very close to a bioluminescent jelly fish. The scene has one infinite light behind the creature with mostly specular, and one spot light to the left of the image.

Oh! Now that's just damned clever, Little Dragon! I was wondering how one might go about creating a "repelling field" glow for the underside of a Dalek. I saw a clip of a "home made" Dalek prop/costume that had a lighting fixture rigged waithin the "bumper" section. An unearthly glow "bled" just beyond the "bumper" suggesting some alien electromagnetic field "levitating" the war machine (instead or simply rolling upon castors). From the few screen captures of the upcoming "Doctor Who" episode. "Dalek", I it appears they will employ similar visuals. I wondered how that (or even "if" it) could be accomplished within Poser. That is perfect! I will try that this afternoon when I return home. Sincerely, Bill

xoconostle posted Sun, 17 April 2005 at 12:51 PM

SamTherapy, good question. I don't have the technical know-how of L_D but perhaps you could use the color picker to sample the hue of the object that you want other objects to "gather," then apply that color to subtle shadowless soft spotlights aimed appropriately? What I want is a relfection catcher in addition to the shadow catcher. Imagine the possibilities if an object could be made invisible with the exception of relfective properties. By the way, I've seen biolumenescent jellies with pink spots at the Monterey Bay Aquarium. Nelif, your jellyfish node is beautiful. Cool work!


Ghostofmacbeth posted Sun, 17 April 2005 at 1:34 PM

Is there a way to combine it with another ambient channel? I am very new to the nodes and really have no clue about them.

It will be in the first service release which will be out shortly. For know what I can suggest is two things. First, save out in revisions, ie save out to a different file name each time. Second you can add the entire scene as a prop to you library pallete. That way if the file does get over written you can just load it out of the libary pallete.[/QUOTE] Aren't these good news? ;)

With what SamTherapy said and this glow technique you could recreate the StarTrek transporter effect by loading an avi in the transparency with noise going from total black to white. Just an idea.

AAAAAAAAAHHHHHHHHH!!! That felt better. :P Now if we can find the shader formula to clear up the noise a bit, we'd really be cooking with gas...


Connatic posted Wed, 20 April 2005 at 6:48 AM

It seems the "noise" decreases with an increase in the sample variable. A Wacro to add Gather to all parts of an object and/or every object and prop in a scene would be useful. Time to try something with 2 different-colored light-props! The possibilities of making animations with animated gather-lights.....candle-flames, torches, etc.

LostinSpaceman posted Mon, 22 August 2005 at 1:33 AM

Step 1 was in Message 6 of this thread. Add that gather node to the object you want the ambient light to show up on. Then add an object with a high ambient channel set to 1 and turn on Ray Tracing in your render settings. You might have to fiddle with the MaxDist (I set my MaxDist to 12 instead of 4 like the screen cap in message 6) settings to get the ground to reflect that ambient light but I got this image with no lights a ground prop with gather node, a Hi Res Spere with Gather node and a cylinder with a hi ambient texture on it. The only light sorce is the ambience channel of the Cylinder.

dante posted Mon, 22 August 2005 at 2:47 PM

Cool...Tks a lot


LostinSpaceman posted Mon, 22 August 2005 at 5:14 PM

PS - I have the same texture node that was used in the diffuse channel of the cylinder plugged into the ambient channel of the cylinder so that the whole texture glows. Then the ambient was set to pure white in the color selector.


svdl posted Mon, 22 August 2005 at 6:16 PM

I finally got it to work. A simple ball with a red ambient color and ambient value set to 1 (I left the rest at default values), resting on the ground plane (shadow catch only off, texture map connected). Default Gather node plugged into the Ambient input of the ground root shader, ambient color white and ambient value set to 1. Works. The Gather node also works when plugged in Translucence, Alternate Diffuse or Alternate Specular. It won't work in regular Diffuse or Specular.

OK, here we go. Let's start with something simple, a ball and a box. We're going to make the ball glow and the box will catch the glow. 1) Start a new empty scene and create a ball prop and a box prop. Put the ball on top of the box. 2) The ball will be the light emitter. Set its ambient color to something else than black, and the ambient value to 1. 3) The box will be the light receiver. Connect a Gather node to its ambient color channel, make sure that Max Distance is large enough (from each point on the box a ray should reach past the ball), set the ambient value to 1. 4) Delete all lights. Enable raytracing and render. Hope this helps, Steven.

For what it's worth, you don't have to plug the gather node into the ambient channel. Alt. diffuse or alt. specular work just as well. You get some interesting results plugging it into the bump or displacement channels, too... :) By using the alt. diffuse/spec channels, you don't have to remember the whole thing about changing the ambient settings - both channels automatically set themselves to white when you plug anything into them. Of course, if you're being complicated in your material setup, and already have nodes plugged into the alt channels, then maybe ambient IS the better course of action. But it's nice to know there are alternatives; if you have a blocked node, then you can always chuck it in somewhere else... jonthecelt


Acadia posted Wed, 08 February 2006 at 3:44 PM

That's good to know. I was playing last night and applied a satin texture to the ball and the texture took the ambient channel plus 2 or 3 others, and I didn't know where to plugin the Gather Node because it seems it's only one node per channel and if I unplugged the texture from the ambient channel and put in the gather node, the texture turned totally black.

jonthecelt posted Wed, 08 February 2006 at 4:44 PM

I did wonder if you could use a math_function node to combine to other nodes. I know face_off suggests doing it with ambient occlusion if you have inputs into either alt diffuse or alt specular (since they have no 'value' setting to plug into, use a math_function set to multiply - value 1 at 1, connected to whatever you had in the channel originally, value 2 also at 1, connected to the ambient occlusion node). Whether this would work elsewhere I don't know - and of course, if you're using colour, you might want to use colour_math instead of a plain math_function, which desaturates all its output. jonthecelt

svdl posted this earlier in this thread to help me:

Quote - OK, here we go. Let's start with something simple, a ball and a box. We're going to make the ball glow and the box will catch the glow.

  1. Start a new empty scene and create a ball prop and a box prop. Put the ball on top of the box.

  2. The ball will be the light emitter. Set its ambient color to something else than black, and the ambient value to 1.

  3. The box will be the light receiver. Connect a Gather node to its ambient color channel, make sure that Max Distance is large enough (from each point on the box a ray should reach past the ball), set the ambient value to 1.

  4. Delete all lights. Enable raytracing and render.

Hope this helps,

Steven.

I also suggest that you look for my post in this thread where I post a screenshot of my material room.  Then read the next few posts down from that.  Try doing the same thing I had done, using a ball and a box.

Yes and yes. Gather in P7 can also use the irradiance cache, just like AO (see Reason #4). In English, this means that you have a slider in the rendering prefs with which you can make it less grainy and render a lot faster through interpolation.

Where did you plug in the gather node and how did you get it to illuminate on those body parts? Did you have to connect a gather node for each part of the body you wanted to illuminate?

Perhaps a screenshot of your material room would help? hint

I want to know how you get it to illuminate on an actual figure such as a mage holding a ball of light where the light would obviously be illuminating the mage's body.

I haven't tried this one myself, but I guess the gather node has been attached to all materials of the mage, probably the Ambient input, while the magic effect has a high ambient value.

You need to set Ambient on the surface you want the glow on to 1 (color:White), and attach the gather node to that surface's ambient color.

Here's a screenshot showing V3's SkinHead material with the gather node attached, and a render with a ball with ambience.

It's been a while since I did that pic.  It was done on a retired computer and I have lost the file, so I cannot provide a screen-grab.  I believe a good starting point is modus0's settings.  Experiment with the Gather settings.  The Gather must be attached to each body part.

Using Gather was so slow, at least when it was first added to Poser, that I gave up using it.  Maybe in P7 with my new computer I can get speedier results!

No problem.

I myself am trying to see if it's possible to have a glowing tattoo on a figure and have the gather node attached to that same material zone glowing as if the tattoo is really shedding light.

So far I've discovered that I need some way to invert the gather effect, which itself has been inverted because of how I did the tattoo effect.

My only problem now is thinking of a way to incorporate it into a 'final' image. There are only so many dark magician images you can make! :)

It's unfortunate the colour gathered is so sporadic. If it weren't for the resulting 'noise', the node would be much more useful.

IIRC, changing the numbers for the node changes what kind of look you get.

A very high sample will generate a more solid "illumination" closest to the "illuminator", although that will slow the render down significantly.

CastlePoser has a nice 2-part tutorial on the gather node (among others) that's fairly explanaory.

Why limit the usage to dark magicians?  I can think of dozens of situations where Gather could enhance a render.  Shaped illumination, like flourescent tubes, plasma beams, glowing robot eyes and back-lit panels just to name a few.

This image, I used gather nod (Floor, walls..except for the wall on the right of image) and two infinites, to light outside of this MechHanger building in helping bring light into a room. This render took two hours, and was worth it in learning how to use this nod. Wonder if P7 is better on the "gather" nod or both P6, P7 the same?

No, I did figure out how to have tattoos look like they're glowing, by plugging a separate texture for the tattoo into the second value of a math function node set to subtract which is in turn plugged into the ambient color.

Getting it to work with the gather node is going to take some investigating, which makes it one more thing I've got on my plate that I'd like to get done.

If it can be done at all.

urbanarmitage posted Tue, 25 March 2008 at 5:40 AM

This is really cool! I've been playing around with it and it has a lot of possibilities.

I have a question though. Is it possible to have an object both 'reflect' the ambient colour of another object and also give off it's own ambient colour to other objects with gather nodes. In other words can an object onto which another is projecting it's ambient colour also project it's own ambient color onto another object or prop.

Picture this - A ball and a square. The ball's ambient colour is set to red and the square has a gather node attached to its ambient colour channel. When you render this the square will show 'reflected red light' from the ball. What I would like to do is set the square's ambient colour to say yellow and have this 'reflected' onto the ball or other props in the scene.

I have tried playing around with a math node to add the gather node with a colour but i'm not having much luck. Can any of the node guru's help out here please? :biggrin:

ThrommArcadia posted Tue, 25 March 2008 at 11:12 AM

**urbanarmitage** I did some quick experiments and I've found that it can be done, but there are some things to consider.

First, The ambient colour of one object may negate anything seen ont he other.  The reason for this (I suspect) is because "Ambient" is supposed to imitate a glowing effect.  In other words, it is supposed to make an object act like it is illuminated (though in a very weak way as shown by the fact that tricks like this are needed for it to actually illuminate anything other then itself.)

In other words darker colours show the gather effect better then lighter colours.

Another thing to consider is what your raytrace bounces are set at in your Render settings.  I set mine to 4 for the test.

Also, if we set up in the way that Little Dragon showed at the beginning of this thread, there will be no appreciable effect.  The Gather Node plugged into the Ambient Colour seems to only produce Black when the colour is set to anything other then White.  I don't know why this is.

So, to get around this I plugged the Gather Node into Reflection Colour.


ThrommArcadia posted Tue, 25 March 2008 at 11:15 AM

In this image I coloured my Ball red and my floor a light Grey.

Both use the same material setting except in the Diffuse and Ambient Colours.

If you look really close you can see a bit of the grey on the bottom of the ball.  You can clearly see the red of the ball on the floor.


ThrommArcadia posted Tue, 25 March 2008 at 11:21 AM

This is a closer render of the same set up.

You can see a grey line a bit up from the bottom of the ball.  This is the floor.

I suspect that playing with the settings might allow one to get a stronger effect, specifically is one could increase the strength of the glow.  This is probably done with the RayBias, but I'm not certain off hand.

A more volumous object then a flat plane might create a more obvious effect as well.

This is what I've discovered thus far.  I have to run to work now, but I will revisit this tonight.

Oh, btw, my setting are set to 'inches'.  I know that in many cases your preference settings change what the numbers mean in the material room.  If you are following someone's sample and they are using Metric but you are using Imperial, you won't get the same effect.


ThrommArcadia posted Tue, 25 March 2008 at 11:25 AM

I should add that there is a distance between the surface and the reflected colour not because my objects are intersecting but because of how I set my gather node.  I suspect the MaxDist has something to do with this, but again I'll have to play more when I get home.

I look forward to other thoughts on this subject.


svdl posted Tue, 25 March 2008 at 1:21 PM

It's the RayBias that causes the distance between the glowing surface and the gathered color. Lower the RayBias and the distance will become smaller.

The Gather node is rather well named - it "gathers" light from glowing objects and adds it to the (non-glowing) surface it is connected to.So the Gather node should be plugged into the material that receives the glow, not in the glowing object itself. The faint effect on the plane is probably pure specular.

Remove the Gather node from the red glowing ball, keep the rest.
Add a Gather node to the Ambient input of the floor material, set the Ambient color to white and the Ambient Value to 1.000. Keep the angle at 180 degrees, so the floor will collect ambient light from all objects that are on its front side.
Increasing the number of samples will reduce the graininess of the effect.

Now render again (don't forget to enable raytracing).

urbanarmitage posted Tue, 25 March 2008 at 1:33 PM

Those are very interesting results Thromm Arcadia! I'm going to give that a try too and see how it works out for me.

I tried it from a different angle and here are my results. I was initially trying to use a math_functions node but I wasn't able to get it to work properly so I switched to a color_math node and I have had some success with that.

My test scene comprises of a ball in the foreground, 2 cones in the middle of the scene, and a taurus with a cone in the center at the back of the scene. All of these are floating above a cloth plane which only has a gather node attached to the ambient channel and the ambient colour set to white.

All of the props have the same setup as you can see above with a color_math node plugged into the ambient colour channel. The node is set to add, value 1 is set to the colour I want the prop to be, and value 2 has a gather node connected to it.

 


urbanarmitage posted Tue, 25 March 2008 at 1:43 PM

As you can see int he render above, i have had some success but there are a couple of things that didn't quite work out as I had hoped.

Firstly, obviously the gather node on the cloth plane is picking up all the different colours of the props very nicely excepting for the ball. I have set all the gather node MaxDist parameters to 500 but this has not helped. Only objects that are quite close will pick up the colour of the props and 'reflect' it.

The color_math node is adding the colours together nicely and giving the product of the colour of the prop and the colour 'reflecting' onto it. There are a couple of issues here though. The math_color add on the blue cone is adding green to its blue and getting a teal colour, the gather node on the red cone is picking up the green and its own red and giving yellow, and yet the green taurus gather node is 'reflecting' both the yellow and red cones as yellow. I'm not sure why this is but i'm going to play around a bit more and try and fix this.

All in all i'm happy so far but any input from you guys on improving this would be appreciated! :biggrin:

I had a similar problem. My Max Dist wasn't nearly enough.

You might want to try a value considerably higher than 500.  Bagginsbill explains it in this thread.

Ahh, thanks for that Acadia! The lady with all the URL's comes to the rescue again! :biggrin:

I've changed the MaxDist to 1000 for all the gather nodes now and at the same time i've been stepping up the samples on the gather nodes. They are sitting on 1000 too now. The graininess is now gone but my render times have gone through the roof!

I'll render out my latest test tomorrow and post it here afterwards.

Interesting stuff urbanarmitage.  I worked way too late tonight and will probably tomorrow, so I might not be able to do anything else for a few days.

I think the colour reflections you are getting are quite natural.  Light works a little differently then the standard pigment colourwheel we all get taught in grade school.  The three primaries for light are Green, Red and Blue as opposed to Yellow, Red and Blue.  Thus when mixed you might get a different reaction the you would expect from something like oil paints.

svdl thanks for some clarification on what the settings do.  I really hope to get to try some stuff soon.

G-night all!

Ok well I had a bit of a problem on my home PC so I haven't posted my latest test render yet. My CPU cooler wasn't doing its job properly and my one core started heating up a bit too much. I got myself a nice aftermarket heatsink and spent last night installing and testing it and i'm running about 12 degrees cooler now under full load.

In my latest render the grainy effect is almost completely gone due to me pushing the samples on the gather nodes up to 1000 each. Unfortunately it has also pushed the render time from a few minutes to around 1.5 hrs but the result is worth it. There are 6 gather nodes in total so the render engine has a lot to calculate.

I have set the MaxDist on the gather nodes to 1000 now but i'm still not getting enough distance between the glowing object and the gather node before the gather node no longer 'sees' it. I'm still playing around a bit with that.

I finally had some time to play with the Gather node in P7.  I was able to re-create the magic sphere glow (using Anton's magic fx) fairly closely.  The pose could be better, and the hand is not lit like the original, but I did get it close.  Applied to Alt Diffuse of all body parts Samples = 50.00 Max Dist = 8600 Ray Bias = 8.6 Angle = 180

Rendered fairly swiftly on 2ghz dual-core.

The graininess can be eliminated by higher Sample rates.

There must be more to it than just these settings.  I applied this to my lightsaber and it just  went black even though the ambiant color is bright red. 

You used a color image instead of just assigning a color so does that make a diffeence?  Are there any other settings elsewhere I am suposed to have activated?

Are you applying the gather node setup to the lightsaber?

If so, you've got it backwards.

You apply the gather node to the surface that is to be illuminated, not the one that illuminates.

Just to review, the gather node is applied to the surface which will receive the energy glow, not the surface that emits the glow.  If you provide screencaps of your material room setup, we can point out the problem(s) easier.

You are aware that thread pertains to using P8 and PP 2010 and their use with IDL.  Also, you did not specify which Poser iteration you are using which leads to a bit of confusion when you mentioned P6 shader nodes.

Hope no one thinks badly of me for reviving this old thread (actually the latest post was just last year so notso old)

 

I´ve read through this several times and have no problem with the gather thing, BUT as far as I can tell noone actually explained the bioluminescense effect, right?

I mean the fresnel-ish effect created by Nalif in the beginning. I don´t mean how to cast ligh onto other objects but how to get the figure to look like a jellyfish..sort of. Glowing edges and transparent/translucesnt in the middle.

 

Thanks a bunch if someone could just tell me in what end to begin doing that and I can prob learn the rest :D

Yeah, I've scoured this thread over and over in hopes of decoding that secret as well.

But it seems this thread went from "how to creat bioluminescence" to "how to setup a gather node to catch ambient light"

I do hope someone would explain and show a node setup.

Because one can cause a surface to glow by using the Ambient channels of the Posersurface/root node in Poser 8/Poser Pro 2010, there has been no further development of the Gather Node (since Poser 7).

To make an aura around an object (instead of making the object itself glow), one needs a transparent envelope around the object (which roughly approximates its shape). That object can be made to glow with the ambient channel (and make it cast no shadow). See the discussion in this thread.

BionicRooster posted Thu, 26 May 2011 at 4:31 PM Forum Moderator

ok, forget everything about the gather node and all that... What we're asking is how to make something translucent and glowy like the creatures early in the thread. I know how to make something glow and make it a light source, just not how to make something look like a "jellyfish".

So, no further mention of the gather node needed, nor wanted in this instance.

apparently nalif didn't post a shader tree for the toad, which may have used stefan's bacteria texture in diff, spec, trans channels and/or alt_diff (if P6 had alt_diff).  P6 didn't have the GIVariables (P7 did have 'em), which means nalif hadda use a rim lite on the toad, which is not emitting lite.  send nalif an IM to confirm.



Miss Nancy posted Fri, 27 May 2011 at 11:52 AM

o.k., nalif is gone.  maybe somebody with P6 can post stewer's bacteria shader tree, assuming it's not a copyright violation. he woulda used some nodes that the rest of 'em didn't know about IMVHO.  but the "toonamal frog" above shows IOR=1.0 approx (no edge distortion).

kobaltkween posted Sat, 01 September 2012 at 11:38 AM

Actually, the gather node is not useful today.  It did a very clumsy job of what IDL now accomplishes in general.  Do not use gather in P9.  Just turn on IDL. 

Gather was fun, but very rudimentary in terms of developing indirect lighting.

There doesn't need to be any new extensions for "bioluminescence" (quotes not to be snarky, but to because I'm assuming this is a very specific effect and not something more precisely modeled after true bioluminescence).   For the edge glow effect , just make an ambient material that takes an Edge Blend.  You can make it with a black inner color and a white outer color and feed it into Ambient Value to just work with one ambient color, or you can set up two different colors in the Edge Blend and feed that into Ambient Color.

That's the simple approach.  If you want to get more creative with your glow, you can do all kinds of things with other nodes.  That's the wonderful thing about a node architecture.  You can always build your way to advanced materials.

Oh!  Sorry, I cross-posted.  I meant that in response to Kamion saying he has P9 but is stuck in P7. 

If you have the hardware to run it, then waiting for a better time to buy P9 is a good idea.  By the time I got P7 it was $20.  They're always pretty good about selling old copies cheaply or giving them away.

P8 and P9 have an interface that probably works better on a newer broad screen then I have, so I just cannot get used to it. P7 I do in my sleep so to say.

Kamion - I totally understand about P9.  Comfort with your tool is really important.  Just to let you know, you can make everything that floats in P7 float in P8 and P9 as well.   That said, I can comfortably shrink my PP 2012 screen to about 1/4 of my screen, where P7 I really could only work at full screen.  I generally find that the new interface has much less dead space for icons and labels that are the same size or smaller.   I'm pretty definitely missing something in terms of what  you're looking for and not finding in the P9 interface, so I'm not betting floating the panels will make things better for you.   I just figured you might not know.

FFD - Just to warn, Fastscatter behaves very strangely and inconsistently when you add lights.  It technically shouldn't do anything at all without lights because it's a shading node, and shouldn't affect BionicRooster's material at all.  I'm betting that it does affect it, which shows how unpredictably it behaves.  That's the reason you don't see Fastscatter skin materials everywhere, why there were all sorts of SSS kluges before P9.  It was completely unreliable, with raytraced shadows producing major errors.



BionicRooster posted Sat, 01 September 2012 at 10:25 PM Forum Moderator

Here's the shader, minus all the nodes for Fastscatter, so this is what you'll actually want to add SSS to, not the one posted earlier.

Yes, it's still true. Ambient Value controls your brightness, Ambient Color your color, and if you want to involve Transparency, go ahead. EdgeBlend nodes give you a blend from facing you (inner) to facing away from you (edge). Without an exact example of the look you're going for, I can't say what elements you need, but those are the most common elements for glowing things.

P8/Pro2010+ with IDL can do much better than the gather node. P11 adds the Superfly render engine, which can do glowy stuff even more easily.

I have some material packs with which you could experiment:
