wish : Color bleeding slider

... this is probably more a general octane wish then a octane4rhino specific one, but since I spent most of my time here, I thought I may post it here as well.


I would like to have an option (slider from 0% = greytone correspondent to the color / texture to 100% = fullcolor bleeding) to control the amount of color which is reflected by diffuse bounces from a material.

Often I have the situation when I have e.g. a wooden floor receiving natural + artificial light, which is then reflected against the ceiling which becomes very yellow/orange tinted.
While this is the expected and correct outcome in principle, I often find the amount of color to be much too intense. A color bleeding option would solve this problem.

I hope this can be implemented despite the fact that it might (or might not?) be 100% unbiased... (actually I don't really know, if different real materials sharing the same diffuse color would emit (or better absorb) different amounts of color...)

best regards

Andreas

Andreas - might be worth consulting the material experts on this. Perhaps there is a combination of filmindex, filmwidth and index that achieves this.

Hi Paul, sounds interesting, I thought filmindex/index/with would only be relevant for glossy / specular materials?
