Sure. I was just playing with lighting effects

Quick, someone hide the thread! All Nalif has to do is shift his color pallette towards the orange, throw a couple of Davo's SFCS sections around it, and we'll be buried under every clueless wannabe who =wants= to make Final Fantasy:TSI with Poser!! 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...
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.
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.

Nalif.. Any chance of getting the material-settings for your beautiful bio-something critters? I LOVE and ADORE that semitransparent glowing effect!

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.

That didn't work :( I ended up with a pink ball sitting on a black box.

Maybe increase the number of raytrace bounces? Two bounces should work.

Ah, I see it. Set the Ambient color on the box to white too. WHen it's black, the color produced by the Gather node is multiplied by "black" - which is zero.

Same as with the box: Connect a gather nodes to the hands/arms/ whatever :o) Mind you, I haven't tried it yet, but...

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
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.

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
