Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 980 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 471.41
Broken: version: 2.93.1, branch: master, commit date: 2021-06-22 05:57, hash: rB1b8d33b18c2f
Worked: (newest version of Blender that worked as expected)
Short description of error
If i deactivate the shadow of a cloud in the Object Panel under Ray Visibilty and switch the preview to Cycles, Blender always crashes on the first sample. If under Ray Visibilty all hooks are activated, it will be rendered without any problems. I am using the latest version, but have already tried an older one, but the result is the same. I also installed the latest graphics driver and tried to change the tile size from 512 to 128, but no improvement. Once I briefly received the following error message before the crash: Launch exceeded timeout in cuCtxSynchronize()
But it can't really be due to too little vram if everything is rendered without problems, if all hooks are activated as i understand it. The problem only affects my cloud.
Here is a picture of the node group of the cloud:
I hope for a quick solution/bugfix if possible, as I urgently need this for a render that I'm currently doing.
