Every time I do export with path tracer on (even on low quality) the proces crushes. New drivers NVIDIA RTX3070 installed. Any ideas how can I fix the problem ?
Hello ,
Thank you for posting in the community and sorry to hear about the crashes.
Here are the things to check:
- Confirm your GPU meets the Path Tracer Requirements (8GB of VRAM, DirectX 12 and DXR compatible). https://twinmotionhelp.epicgames.com/s/article/Path-Tracer-Requirements
- Windows 10 version is updated to at least 20H2, 21H1 or 21H2 (Go to Windows Setting -> System -> About to check)
- If you have more than one GPU also follow the instructions in this article to make sure you are using the correct one. https://twinmotionhelp.epicgames.com/s/article/Use-your-dedicated-GPU-with-Twinmotion-on-a-Windows-computer
- If the above conditions are met and you are still having a crash try to add a TdrDelay by following the instructions in this article: https://twinmotionhelp.epicgames.com/s/article/Video-Card-GPU-Crash-during-export-using-Path-Tracer-Long-computation-times-TDR
