Hi,
I'm using ctrl buffer to output render passes with mental ray for Maya .All my passes like color,diffuse,specular,reflection,ambocc are all working fine..
Have 2 point lights in my scene and I'm using fg with an exr plugged to an ibl node for indirect light.
What I want is a pass with only the direct lights and another one with only the fg . Have no problems to get the fg pass to work properly...linked the lights to an orenNayer shader (mib_illum_lambert seems buggy) in mode 2 to exclude the direct light contribution.
Here is my problem.... the direct light pass still has some fg/ibl contribution....turning down the fg-gain in the ibl node works...but that also turns off the fg pass. tried using ctrl rays , raytype and p_ray_type but can't seem to turn off the indirect light contribution in the direct light pass.Sounds very basic but can't seem to figure this one out.....
cheers,
Sajeev
