VRayOverrideMtl not working when textures are used

[Alex_M]

I was rendering an interior when I had to use a VRayOverrideMtl to boost the reflections of the background plane. To my surprise, VRayOverrideMtl did not work even though it should be fully supported according to the GPU supported features list. Is this a bug, or am I doing something wrong? What's interesting is, if I remove the texture, VRayOverrideMtl starts working. It seems that it's only when I put a texture that it stops working. I also tested with a very simple scene and it still didn't work. Attached are the scene and a screenshot.

Thanks for the report. The color multiplier of VRayLightMtl is not considered when mapped and used in a VRayOverrideMtl. I've logged the issue (internal bug-tracker id: VGPU-6119). As a workaround, you may use the multiplier of the map itself (Render/Overall multiplier) or through an Output node. Another thing that works is using a VRayMtl with Self-Illumination instead.

Thanks! Using an Output map did the job.
