Hello,
I have tried to solve this problem for the last day, but was not able to find the source of the issue. Usually all scenes render quite flawlessly with Arnold for me, but this one I just can't get to work.
The render process starts without problems, but always crashes on the second frame, no matter what frame is the first one. A day ago for some reason it managed to render about 50 frames without crashing, but I could not reproduce this effect.
I have attached the bugreport. I would be really glad if someone from the team could look into it quickly, I am at the end of my wisdom here, but I feel like I might be missing something obvious.
