Missing material maps on user library objects created in TM 2022

Reported by user in SF [Link Removed]

User library assets created in TM 2022.2.3 or older will not contain texture maps for their materials when the .tmi file is added to the TM 2025.1.1 User Library.

The issue was not present when adding the .tmi file to the User Library for TM 2023 or 2024 versions.

The issue does not occur when creating and saving the model to the User Library in TM 2023 or TM 2024, then converting to TM 2025.1.1.

 

Download attached files or use any model containing texture maps

1. Open TM 2022.2.3 or older
2. Import the model into TM
3. Save the model to the User Library
4. Copy the .tmi file to the User Library for TM 2025.1.1
5. Drag the asset into a 2025.1.1 scene

Result: Asset will not contain material textures, but the thumbnail preview will still properly display materials.

-In an intermediate version of Twinmotion (such as Twinmotion 2023.2.4 or 2024.1.2), add the .tmi file to this version's user library
-Add the object to the scene
-Resave the object to the User Library
-Copy the new .tmi file to Twinmotion 2025.1.1's User Library for all material maps to be conserved
