Unreal Engine 4.11 Preview

Having an issue with Skeletal Meshes.

The cube on the left is correct, and is a static mesh. The one on the right is the same mesh imported as skeletal. Notice all the dark splotches? They persist when I disable shadows as well!

Whats going on here? Sort of likes like the skeletal mesh has some smoothing or something applied (although the angles are 90 degrees). It is only like this for newly imported skeletal meshes, but the ones I imported before 4.11 look correct.

EDIT: It turns out it’s a problem with the normals. Switching it from MikkTSpace to BuiltIn fixes the issue.
