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.

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

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.

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?

coolstuff LD!...I'd been looking for somekind of light emitting materials in P5

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 :(

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.

Wow !!! Incredible ! This is really cool !

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

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

Very coll stuff. Is there any way to simulate this in P5? I know about using the Ambient channel for self illuminated objects but how about a P5 equivalent of the Gather Node?

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!

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.

Ghost, you might use the blender node to create different ambient effects...

"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." No problem. Gimme a few and I'll post the Material room settings.

Only one word: Beautiful! ;) BTW: I have good news about the Memory Bug from Poser 5 /6! ;) I recently received word from CL [QUOTE]Yes the engineers have found a bug that could be the cause of the problem. 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? ;)

Ooooooo.... Now I want time to experiment with the shader nodes, darn it. Must learn to give up sleep so I will have enough hours in my days.

SamTherapy, I wouldn't have come up with that reflection catcher solution on my own. THANK YOU! :-)

Just for a fun render could someone do a test render with the Magik Particle figure I made?

xoconostle, you're welcome. maxxxmodelz came up with the basic shader, which I tweaked to get the colour working, so maxxx deserves the credit.

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.

Cool! I can see flames actually casting light using this feature.

Hm, i don't get it.. :o( What material settings does you use, to make your Probs (Box, Moon...) glow?

Anton; If someone doesn't beat me to it, I'll give that a whirl this weekend (assuming the new new motherboard works). It'll be Thursday before I can start rebuilding the main system though, so if anyone else cares to go for it do!

I have to go look for my old stuff. I uninstalled everything but my current projects. Just being lazy. hehehe.

I'm working on one...maybe I'll have some tests up tonight. That's the goal anyway.

Very interesting indeed!
Bookmarking.

And more images pleeeeeaase! Love it.

Here's another one. This one doesn't have a gather node on the ground though.
