I am facing this problem that I haven had before.
I have this large lobby, most of the walls and flooring are light gray or white, but there are these Birchwood slats (image), and they are creating this incredible color bleed.
I tried to desaturate the wood texture, but I am loosing too much color. Is there a way to overwrite the color bleed for that object or material?? or any other workaround?
Check the diffuse boost setting in your material.
