Is Opacity Map for VRayLightMaterial not supported for GPU rendering?

[JezUK]

I have a scene of a fireplace which I purchased online - the scene works fine/well using CPU rendering, but I prefer to use GPU rendering as that's where my hardware investment is being made.

Using GPU rendering, the flames for the fire don't work / show - I would like to know if this is because the way the material has been created isn't supported in GPU rendering?

UPDATE: I've just noticed that when set for GPU rendering, the VRayLightMaterial Map Slot becomes greyed out (and this particular material uses a VRayBitmap in that slot, so maybe Maps aren't supported in VRayLightMaterials for GPU?).

The only option that is not supported on GPU is the "Emit light on back side". Can you attach a simple scene with the shader and assets so we can troubleshoot?

Sure, thanks Aleksandar, I'll sort that out now for you, give me a few mins.
