R20 Team render clients crash

Hey,

I am using Cinema4D R20 and the latest arnold update. Everytime I hit the team render button some render clients crash instantly. I start with 20 clients but four renderings later there are just 8 available. Any ideas how to fix it?

I had this issue in R20 also, but only when opening files originally saved from earlier versions of C4D or Arnold. Pasting the scene into a new file and manually re-entering the render settings fixed the crash issue — though still have color consistency issues between machines.

Thank you Alice. I always used the render settings from R19. Hopefully this is the solution.

Let me know if that solved the issue or not. Would be interesting to know if it's related only to Arnold or happens also with the Standard/Physical renderer.

Could you please confirm if te Standard rederer works, so it's only an issue with Arnold? Do you have maybe a bugreport file or Arnold log on the clients which crash?

Sorry for getting back to you so late. So far I'm not able to reproduce the problem, I don't have that many clients though. I don't see any c4dtoa related calls in the bugreport files, so I'm still not sure it's a bug in Arnold and not in the R20 Team Render. Can you test different renderers?

Aslo I wonder if this happens with any scene, or maybe there's something in one specific scene which triggers the issue? Is it single frame render or animation or both?

This sounds like the issue is related to R20 Team Render and not specific to Arnold.

I have the same issue, physical render. Animation or png sequence. It’s a heavy duty file though but still... don’t remember these issues with r19... debating on going backwards in version

I see some R20 fixes on the MAXON beta forum, which has not been released yet. If you have access to the beta, please give it a try.

Maxon told me to uncheck peer-to-peer box in the team render Settings. Now it works better.
