    Is VRayLightMtl not supported in GPU ?

    I'm doing a project right now on which a VRayLightMtl for some of my geometry would be really great for but it doesn't seem to work - yet the docs say that VRayLightMtl is supported for GPU ?

    I switch to CPU and the LightMtl works fine......

    I'm using Progressive rendering in GPU, CUDA..... I'll be disappointed if it indeed doesn't work....

    My software / hardware is as below in my signature.

    Many thanks.

    This does work on GPU (used it today even) so perhaps it is one of the settings, maybe it is turned to 0 in lightmix, or the geo is emitting on the inside?

      It was the Self-Illumination in the Light Mix
