When importing a Static Mesh if you use the default settings and then manually import any LODs for that static mesh they will be rotated by 90 degrees.

I found that disabling Transform Vertex to Absolute on the initial import of the base mesh (LOD 0) will correct the issue. This functionality is a regression of 4.11.2 where the option for Transform Vertex to Absolute was present, but did not cause this issue. This affects 4.12 release and 4.13 Dev-Main CL-2986935

FBX export versions checked:

Steps to Reproduce

1. Open UE4
2. Import any test asset (one attached if needed)
3. Open the actor in the SM Editor
4. Manually import another asset for the LOD 1 (Use the same attachment if need)
5. See results.

Regression: YES

Results: If using the default settings on import of the base mesh the imported LODs will be rotated by 90 degrees.

Expected: The LOD should not be rotated.

Disable Transform Vertex to Absolute on import.
