Particle Geometry Instances - Different Colour?

[danylyon]

mhmm.. anyone?

[alexx]

this tread should be in the dynamics section..

anyway: i think mayas particle instancer cant handle something like that.. (at least up to 4.5)

argh.. not again.. well Thank you alexx :)

Mhm.. I thought my question was more about Shading and general Maya, that's why I put it in here.. sorry.


I'm going to make It different now.. but I'm already running in a new problem.

Say, I have a hundred different Polygon objects. All of them have the same Shader with a solid colour (obviously the same).

Now, I would like to have different colours.. Basically a RAMP from Pink to Blue over all those 100 objects. (with each object having a unique color)

How can I make this?

if you are a bit into mel, you could create a ramp with the desired colors.
then use a rand (0,1) and plug the result in the vCoord value from the ramp. (v-Ramp presumed).

now you can read out the outColor value from the ramp (which is randomly different, when you invoke the rand(0,1) again and again..

that color value you can plug in the shaders color to have them differently colored.

cheers
