GPU render doesn't work for second scene

[Micha]

Hi,

I'm working on two interior scenes and I need to apply the changes from one scene at the other scene. So, both are open. I can render scene A, but if I try to render scene B, the GPU rendering doesn't work for scene B anymore, I get a lot of error messages. If I restart scene B than I can render this scene. Each scene needs approx. 2GB VRAM only.

Hi,

Could you please share the project with us so we can investigate in detail? If this is alright, please send us an archived copy (V-Ray > Pack Project) via email or a file-sharing service of your choice

Some days later now I tried to repeat the situation but it works. Also rendering both scenes at the same time is no problem. I will keep my eyes open.
