Hello Tomas,

Thank you for contacting us and reporting this issue you have faced. Based on the crash details I recommend you follow the steps in the following article and add a TdrDelay and see if that resolves the problem on your end.

https://twinmotionhelp.epicgames.com/s/article/Video-Card-GPU-Crash-during-export-using-Path-Tracer-Long-computation-times-TDR

If not please check to see if you have MSI afterburner with Riva Tuner installed or any GPU performance application running and disable or turn them off. Here is another article to reference that could be helpful.

If you are still experiencing those crashes after doing the recommend steps above please you check the drivers of your graphics card and that they are the latest. If you have 2 GPU make sure to dedicate the correct one for Twinmotion.

Hello Vincent

i was hoping that the hotfix would bring a solution and have been experimenting over the weekend. Unfortunately without success.

Unfortunately I am absolutely lost.

I have adjusted the delay values under Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDriversange. The entry was present in the registry but was set to 60. I adjusted it to 15.

I have and had never Afterburner or Riva in operation, also I have only one GPU installed.

The error is also 100% reproducible. In fact, it is not my file that is faulty, the error also occurs with a new file and with the Lakehouse demo. On my MacBook Pro with M1 Max everything runs without problems. Of course a bit slower and unfortunately without Pathtracer, which I really do need right now.

Nevertheless:

It also does not depend on the path tracer, it also happens without.....

I have uninstalled and cleaned everything, reinstalled, and still the error occurs within 2-3 minutes:

New file, work a bit... and crash!

Open demo lakehouse, load pathtracer video, export video, time is displayed with about 1h 20min and after about 5 minutes crash.

No matter if with or without path tracer the program crashes after short editing.

I am really at a loss.

What can I do to be able to work with Twinmotion again?

With the request for help and quick feedback.

Hello

Do you have any news for me. I am truly at a loss and can't work without it.

Many regards

Hi Tomas,

Vincent is out of office this week, so I will be assisting you for now (I will be closing the discussion post you made on the Community referencing this case and continuing working out of this case to keep things organized).

Looking at your crash logs, I'm not entirely sure what could be causing this issue, as this is an issue that should have been resolved back in previous updates and using the regedit method to adjust the TDR delays.

Looking through your crash logs, I do see that your GPU drivers aren't on the latest versions, so it may help to update them and see if that resolves the issue. You can download the latest drivers from here: https://www.nvidia.com/Download/driverResults.aspx/193713/en-us/

If that doesn't work, please let us know and we can look into other possible solutions.

Best,

Raghib

Hello Ragib

Thank you very much for the response.

About the case:

I have installed the Studio driver in the latest version, because I have been reading on the web that the Studio driver is the right one for Twinmotion. A new release came on 10,18 2022. The problems nevertheless are the same TW crashes within minutes. Without load, just as it is....

I have also tested the game drivers, unfortunately with the same effect.

Which way to go?

Greetings from Vienna, Tomas

BTW.

Everything runs perfectly on the Mac. Despite Rosetta emulation. Unfortunately without Path Tracer....

Hello Tomas,

Thank you for the follow-up and your patience. At this time I am not certain what could be causing this behavior and suggest you report a bug directly by using the contact us button on the home page or this link: https://twinmotionhelp.epicgames.com/s/case-community-page

Kind regards,

Vincent B.

I have posted the bug report and hope for quick help.

Hello ,

Thank you for submitting a bug report and hope you were able to resolve the issue.

Kind regards,

Vincent B.

Vincent,

how is it that this has been occurring for over a year and the problem has not been pin pointed?

I too am having this same exact issues with a ryzen 7 5800X and 6900XT on a install of Windows 11.

It appears that the TdrDelay fixes the Nvidia crashes but this is not the case with the AMD cards.....

When can we expect a fix for this that works? I do not have Rivera tuner or MSI afterburner installed and I have AMD pro driver only without the additional software as it includes all that in the software suite....

Hello ,

Thank you for your reply and there are issues that have been addressed with AMD card in recent driver and engine updates with Twinmotion 2023.1 Preview 1 we are using Unreal Engine 5.0 and there should be improvements with those GPUs.

Since everyone has sometimes different configurations we need to investigate as much as possible and make sure we have everything properly documented for the development team to best resolve. Thus could you please report a bug and let us know if the crash are also occurring for you with the latest Twinmotion version? https://twinmotionhelp.epicgames.com/s/case-community-page

Thank you,

Vincent B.
