Controlling a shaders colour bleed?

How do i control how much of one objets colour that bleeds on other objets, without changing the look of the shader. I tried changing the irradience values, but it also changes the ambient colour of the objetc.

thx. a lot

you should be able to control more or less just the color bleeding via photon shaders...

for example, if for whatever reason, you have a white ball that you want to bleed as orange onto a surface, you'd have the material set as white, and the photon shader set as orange...

this way the light would be white on the object, but the photons would react as if the object was orange...

I hope that helps : )
