SKP Import - Applied texture maps from previous Twinmotion versions are lost after reimport in TM 2025.1.1

Reported in SF [Link Removed]

For SKP imports that were added to a file in a previous version of Twinmotion, when the .tm file is concerted to and opened in TM 2025.1.1, if the SKP model is re-imported or refreshed, any applied texture maps will be lost.

This behavior did not occur in previous versions of Twinmotion, and does not appear to occur for other file types.

This only occurs when the texture maps on the model were applied in a previous version of Twinmotion. Any texture maps applied to the model after being opened in 2025.1.1 will be preserved upon reimport.

Attached is an example Twinmotion 2024.1.2 file where the issue occurs.

1. Import an SKP file with materials into Twinmotion 2024.1.2
2. Edit one of the materials and apply a new texture map to one of the texture channels
3. Save the .tm file
4. Open the .tm file in TM 2025.1.1
5. Click the refresh/re-import button on the imported file thumbnail

Result: The applied texture will be removed from the material.

 

Manually re-apply the texture after reimporting in TM 2025.1.1, or use Datasmith.
