UV artifacting on import

When I import my FBX mesh there is artifacting on the parts of the UV map for AO and environment. Im importing this mesh from Blender and there aren't any modifiers being applied. Shading both smooth and flat on export does not change anything. Baking mesh maps does not help.

Example:

(artifacting on hands when importing the FBX mesh into SP. The rest of the UV is fine)

If anyone might know what might be happening here I'd greatly appricate the help, Thanks!
