Hey there,

Unreal Engine 4.11 imports any skeletal mesh all smoothed, like if there are no smoothing groups specified. The same meshes work great if they are imported like static ones.

This issue doesn’t happen on 4.9, and we’ve tested different meshes from blender and autodesk, so we suppose it is a bug in Unreal Engine’s FBX import module.

My local machine is Windows 8.1  
Same issue on forum with a screenshot [Unreal Engine 4.11 Preview - Announcements - Unreal Engine Forums](https://forums.unrealengine.com/showthread.php?94321-Unreal-Engine-4-11-Preview&p=450348&viewfull=1#post450348)

Hello -

We are currently tracking this known issue as UE-25264. I have added your additional information to the report and will keep you informed as we continue to investigate a solution.

In the meantime, if you select Built-in instead of Mikk TSpace in Normal Generation Method, the mesh should import with correct normals.

Thank You -

Eric Ketchum
