Hi all. I wanted to share my findings with ongoing Datasmith crashes to my Arch Viz project and my solution.
If you are experiencing crashes this might help. In the Fatal Error log, note the materials being flagged (usually shows that they can’t be renamed on top of another), find them in your Content Browser, and simply rename them.
This might work a few times over, you think its all ok, but then it starts again after a few more Datasmith imports. If so, I recommend you do not tick ‘materials’ when importing the Datasmith. Again this will suck if new materials are needed, but the Datasmith should work.
Unreal Engine: this is an ongoing issue for UE and Twinmotion Datasmiths, usually when the file has several imports. Urgent request to fix, as this can really make it stressful when nearing end of a project and you can’t continue!
Hope this helps
