Twinmotion 2022.1 (FULL RELEASE) crashes when I activate the path tracer

Development Getting Started & Setup

I have a computer in the studio with an AMD RX 6700 RXT graphics card but it crashes every time I try to activate the path tracer function. Does anyone know how to fix this?...I am tired of this problem.

The message that appears is as follows: Fatal error: [File:Unknown] [Line: 684] hr failed at D:/tm/workspace/Release-2022.1/Engine/Source/Runtime/D3D12RHI/Private/D3D12Resources.cpp:451 with error DXGI_ERROR_DEVICE_REMOVED with Reason: DXGI_ERROR_DEVICE_HUNG

Thank for the response, but I read an other post with the same problem 2 months ago. Tell me if you are working on solving that issue with the AMD cards or if it's an internal problem from the graphics that doesn't allow to finish the pat tracing.

Thank you!

Hi

I love twinmotion but I too have the same problem and have tried all the solutions.

My configuration is:

NVIDIA GeForce RTX 3080

AMD Ryzen 9 3900X 12-Core

128GB RAM

and the error is always:

Fatal error: [File:Unknown] [Line: 684].

I hope a solution can be found soon!

Thanks

Hi ,

Thank for for the follow-up and I had not looked carefully that you do have an AMD card and that TdrDelay does not always help. I assume you have tried but it did not make a difference?

We have been working with AMD to better integrate the compatible cards with Path Tracer and our teams are investigating this problem. Thank you for your patience and understanding while we work on improving this.

Kind regards,
