I’m experiencing an issue with Google 3D Tiles imported as 3D files in Twinmotion.
After using the Model Edit tool to delete/remove unwanted parts of the model, the changes appear to work correctly. However, after saving, closing, and reopening the project, the deleted geometry reappears.
The same issue was present in Twinmotion 2026.1, which I previously reported, and it still appears to be unresolved.
This is extremely time-consuming when working with large 3D Tiles models, as I have to repeat the cleanup every time I reopen the project. Due to the size of these models and the risk of crashes, I sometimes have to keep Twinmotion open for days to avoid losing this work.
Expected: Deleted geometry should remain deleted after saving and reopening the project.
Please investigate this issue, as it significantly affects the workflow with Google 3D Tiles.
