vraylightmtl opacity GPU

as title, does it work in some way? ive got stuff set up with opacity mapped light materials, and they render fine on cpu, but with black instead of transparent on GPU. am i missing some trick?
-ive now swapped to self illuminated vray materials with opacity maps. that does work, but i miss the handy “compensate camera exposure” tickbox.

We are aware of the limitations there. If you send me a simple scene and what you’re trying to achieve, I can try to think of something.
