We are recently experimenting with the new 4.22 engine and exporters. I’m testing both the Revit and 3ds Max exporters (using the same scene from Revit for both). We encounter an error message stating we don’t have permissions to save out content on import and also when trying to save. Ultimately the content will not save, and if we close and re-open the project these assets will be gone.
It’s happening with a variety of different assets in different scenes, and we have seen furniture like desks display this issue along with walls and other objects.
This exact same scene imported into UE4.21 will experience NO issues (even when using the 4.22 exporters for Max and Revit). Until we can resolve this our team must continue building projects in 4.21.
