VrayMeshLights extreme long render times

[peprgb]

@simmsimaging

Is it possible to attach a simplified version of your scene - just the walls / floor / ceiling / lights and screen/cover object which hides mesh-lights.
Thank you very much in advance.

For sure, here is attached, the thing is curious because with another really similar scene i almost dont have differences in render times with 8 or 32 subdivs on the VrayMeshLIghts.

Try rendering with 8 subdivs and 32 subdivs (they are 2 separated mesh lights, but attached the problem was there too).

Thanks,
