FBX Import flips faces of mesh on Import for static meshes

User is reporting that this is happening with some, but not all meshes. I didn't see anything out of the ordinary when looking at the asset in 3Ds Max, and the asset will import correctly into 4.10.2, but not in 4.11 and 4.12 MAIN. Looking at the imported normals the faces are flipped but the normals are correct for what they should be.

When testing this I adjusted a number of the Import Settings to see if this would resolve the issue.

Import Settings:

• Tried all variations of using Built in and MikkTSpace with the Normal Import Method.
• Tested with FBX 2013, 2014 and this is producing the same results.

Working: 4.10.2 CL-2818068
Not Working: 4.11 P4 CL-2843242
Not Working: Dev-Main 4.12 CL-2847722

1. Open UE4
2. Import attached asset as Static Mesh

Regression: Yes

Results: Faces are flipped for the asset but the normals indicate the normal is still facing in the correct direction when checking in the Static Mesh Editor

Expected: Faces should not be flipped.
