Did anyone have a solution to this? I’m facing the exact same problem …
[EDIT] I just found a work around:
The problem seems to happen (or not) depending on your export paths in the Send To Unreal settings dialogue .
I can export without this error when I have export path set to:
- Mesh:
/Game/Assets/Blender/ - Skeleton:
/Game/Assets/Blender/Animations/
Same file, only change being the export paths, throws errors with:
- Mesh:
/Game/RnD/TestArt/ - Skeleton:
/Game/RnD/TestArt/Animations/
But this set works again:
- Mesh:
/Game/RnD/TestArt/Assets/Blender/ - Skeleton:
/Game/RnD/TestArt/Assets/Blender/Animations/
So some combination of needing Assets or Blender in your export paths is needed to fix it. I don’t know why are exactly what the requirements are, but it’s working enough that I don’t care so good luck to anyone else in future with this issue!
(Note: This is all with UE5.1.1 and Blender 3.3.1 and SendToUnreal v2.3.0)
