Color Bleeding [Solved]

[40th]

I have a scene with few saturated materials which affects the color of white material surfaces.
Is there a v-ray (not post process) solution for this issue?

You're using IR?
Apply a different colour to the offending materials with less saturation, save the IR map - then load that IR map in your original model.

Thanks thom.
I found a very good solution :

No, that's actually a rather poor solution. Decreasing the saturation is like turning you're colorized GI solution into a grayscale one. Yes it works in that very simple situation, but in anything where there's more going on it will lead to a very flat result as all of your light will essentially have no color in it.

Long term the best solution is the Override Material, which we don't have yet. The next best thing is to calculate your light maps (Irradiance Map and Light Cache if you're using it) with a desaturated version of the material that is causing the color bleeding, save it, swap the original material back in, and render.

I've set the saturation to 0.3 and all my white areas stays white and the colored ones remains colored just a lil. bit desaturated.
I'm pleased with the result...

Here's the scene that i've reduced the GI saturation to 0.3
I didn't changed the saturation in post processing (PS)

As you can see i have few colored (saturated) materials which were affecting the white areas. So if used the method you (Damien) suggested it would complicate the pre-render work, considering i had to change p.o.v and and render resolution from time to time.

Re: Color Bleeding [Solved]

I'm curious about the "colour bleeding" issue which pops up on the forums now and again as I've never run into it in any of my projects. You're not using 255,255,255 white materials are you? Could it not be that your saturated materials are just too saturated?

Re: Color Bleeding [Solved]

From what I understand - for visible colours you should never use a 255 value.

No, my white were 233,233,233, which is far from 255.
And the first color to bleed was the wall plaster (light pink), which had 13/100 saturation (su's editor).
