Less Color Bleed in Vray

[chodney]

I'm new to Vray, switching from Mental Ray and wondering how to adjust color bleed of a texture mapped material.

For instance, I have an interior with full height glass, and target direct light coming down on a wood floor. The wood floor bleeds a ton onto the white gwb walls.

I'm using all Vray materials.

Hi Chris,

 

try right clicking the object/s with the material that you want to adjust. then there's a vray properties dialog, decrase the GI value. that should decrease the bleeding.

or play with saturation in the indirect illumination tab

What I tend to do is replace the offending material with a white material, render out the irradiance map only and save it. I then reassign the proper offending material and render using the saved irradiance map.

Use exponential colour mapping. It bleeds all colors you need and dont need.:-)

True... but a more "correct" olution would be to use Gamma Corrected with values of 0.4545 (which is 1/2.2) on both light and dark.
