Hello ,
Thank you for the follow-up and feedback.
We are currently working on the auto upgrading system for tmi items to avoid having to redo all files but if you encounter issues with some items, it is most likely those are from Twinmotion 2019 or earlier thus recreating and resaving those user library items in a 2022.2.3 version first will help to them convert them for 2023.1.
Please reference our release notes for details on the file format change:
https://www.twinmotion.com/docs/en-US/twinmotion-release-notes/twinmotion-2023.1-preview-1-release-notes/
Here is additional information on a proper workflow to save those items forward:
- Open Twinmotion 2022.2.3 and place all assets in your scene from your user library that you want to use in 2023.1.
- For objects simply drag and drop them from the library into the viewport
- For material/surfaces place a simple primitive object/shape to drag and drop the material onto. Repeat for as many materials as needed. Tip: Once your first primitive element is placed, select it and press the Shift key then click on directional arrow from the gizmo. This will create a copy and open the copy window to make additional copies.
- Once all your objects are placed you can save the Twinmotion file.
- Reopen the file in Twinmotion 2023.1 and save the library assets to your new user library.
Hope this helps.
Kind regards,
Vincent B.
