hello!

can anyone tell me how i can read the instance number of point instanced geometry ($IPT maybe?) into a vop shader (i want to randomly generate a colour per instance)

i have seen it done by directly modifying the shader atributes with opdef, but you are essentially applying a new shader to the instance, i dont realy want this as the instanced objects already have shaders applied..

as in my scene.. the instances are from 6 different models, each model has a unique shop (all from the same vopnet though).

can i modify the attribute (colour or whatever) in the already applied shops?



hope that kind of made sense..

ta,

Mark
