My laptop cannot run the Twinmotion 2023.1 preview 2.

My laptop cannot run the Twinmotion 2023.1 preview 2, but I have a project working under preview 1. Now I cannot return it to continue and complete my project. Please give me the preview 1download link.

I have a similar problem... My file file saved on TM 2023.1 Preview 1 can't open in this version... And i can't find old version to download. >:-(

Same here! The new 2023.1 Preview 2 release crashes when converting a project from the 2023 Preview 1 version, but I'm also unable to open it from the original Preview 1, since it's no longer an option from the Epic Games Launcher.

Please provide a swift solution, since it has completely made it impossible for me to finish a project!

Thanks

I can't use path tracer in new version even opended the direx 12

This is worrying. I have ongoing projects built in 2023.1 Preview 1 - now when I start TM from the launcher it automatically starts "updating to Preview 2". Should I cancel the installation in order to keep working in Preview 1?

same issue here. 1660ti, used to be able to PT without a problem, with 2023 Preview 2 I cant use the pathtracer..

For me, path tracer is working but with some wired linear shadows, looks like shadow bias scale is too small, but I can not find where I can change in in path trace mode

same problem with pathracer, GTX 1070, Directx12 enabled and not works..

Hey,

Same issue here. Project made in 2023.1 preview 1 crashes when opening in 2023.1 preview 2.

Tried merging, changing DirectX version from 12 to 11 makes no difference.

Is there a way to give us the ability to download 2023.1 preview 1 again?

We now have a project and no way of opening it.

Similar here, ​2023.1 preview 2 kept loading for a century, reinstall cannot fixed it. lucky can use the older version 2022 instead.

Same problem on 2 different computers, constant crashes when opening preview 1 files. Pathtracer in constant loop and crashing. Can we go back to preview 1? Any ideas how to fix it? I took a risk and updated to preview 2 when working on the presentation. Please, help.

Hello ,

Thank you for the follow-up and we should have addressed the majority of the crashing issues coming from Preview 1 files. If you are still having those problems with the latest update on the 3/20 for Preview 2. Please contact us directly by using this link:

Hello ,

Thank you for posting in the community and this seems to be an issue with the geometry origin (distance too far) / scale / Skew and the UV doesn't seem right in PT. Are you importing SKP files and is this happening if you use Datasmith.

We are still investigating this and recommend you send a bug report with an example file: https://twinmotionhelp.epicgames.com/s/case-community-page

The current workaround is to change the near clipping value and increase it of using the Depth of field setting.

Hope this helps.

Kind regards,

Vincent B.
