Subject: Creating bioluminescence with P6 shader nodes?

hmmm.... Renaissance with bioluminescence... an interesting thought... ;) jonthecelt

OK, I'm doing something really wrong because I'm not getting anything like these samples. Can someone please explain "Gathernode for dummies?"

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.

stewer - when poser 7 is released, do you have any new tutorials planned?



stewer ( ) posted Thu, 30 November 2006 at 5:33 PM

Certainly thinking about it, but the first thing I'll do once Poser 7 is released is turn off the computer and go outside. There are people and things in my life that didn't get the attention they deserve or require, and I really should catch up. First of all, my wisdom teeth are due. :unsure:

I got the ball and box to work ok, and the ball and floor but I just can't get the gather node to work on a model.  Something I'm not doing right, I'm sure, but I'll keep playing with it.

I, also, can't get it to work at all in P7.

I actually had it working in P7. I got Nybras to give off an aura that looked pretty cool.

Maybe if you post a pic of your shader tree someone can help you out?

> Quote - A render with Gather illuminating with Anton's Majik spheres. No lightsources.

Can you tell me how you achieved that effect?

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

Ditto that!

I got the ball on the box but that's all I've been able to achieve with this.

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.

svdl ( ) posted Mon, 26 February 2007 at 3:38 AM

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.

Acadia ( ) posted Mon, 26 February 2007 at 3:53 AM

What confuses me is do I connect the gather node to the Diffuse Ambient  channel of the item I want to glow... or do I connect the gather node to the item I want the glow to be on.. IE: V3's skin texture... or do I connect a gather node to all of it (Item I want to glow plus V3's skin texture)? 

Whatever I have been doing doesn't seem to be working.

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.

I've had allot of fun playing with this.

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.

Very cool none-the-less.

modus0 ( ) posted Tue, 27 February 2007 at 3:39 AM

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.

And I've got a scene in my gallery with a skeleton and glowing eyes.

You can also do things like luminescent aliens (ala The Abyss), or radioactive individuals.

It is also good for lighting up lamps too. Anton posted a wall sconce in another thread where he used this technique and it actually looked like the lamp was really lit and casting light on the wall.

Wow..this thread helped. Awesome thread on the "gather" nod. And I had it the other way around when it came to receiving, transmitting light and couldn't succeed. 

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?

Modus0, have you found a good, solid way of creating this effect?


modus0 ( ) posted Thu, 30 August 2007 at 12:56 AM

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.
