Inverted Normals Problem!

Update: I fixed the problem

Do not use the regular Mirror on an object in 3ds Max, instead put the modifier Mirror.


I export an object from 3ds max as FBX which Normals are facing correctly, but when I import it to unreal engine they are flipped even through in the static mesh editor the Normals shows correctly, but they appear not!

Anybody had this problem and solve it?

Thank you!
