Hi there,
I'm new to the forums and haven't been working with Vray for long, so excuse me if I am not so knowledgeable. I am trying to set up my scene for rendering with a few Render Elements, nothing too complicated. The scene is an interior illuminated with a Dome light, a VRay rectangle light and two stained glass windows that have a VRay Light Material applied to them. So, the elements that I am using (well, the ones relevant to the lighting of the scene) are GI, a Light Select for the dome light, another Light Select for the Rectangle Light, and Self Illumination for the stained glass windows. Everything seems correct to this point. The thing is, both stained glass windows have the Direct Illumination checker (under the Direct Illumination tab on the attributes of the Light Material) set as active, so the material emits light. And I don't know how to extract that light contribution to a separate render pass... The composite of my render passes doesn't look like the RGB pass, it's missing just that bit. Could anyone give me some hints on how to do it or point me to any tutorial? I have been looking for a while with no luck. Any help would be greatly appreciated
Cheers!
