Duplicates with SubSurfs

Support Basics & Interface
1

Im modeling a face, or lets say i’m trying. :wink:

When I model one side, using subsurfs, I duplicate it and reflect, and everything looks fine. When I join the two meshes the newly created side turns black. Even with the Double-Sided not pressed.

What should I do to resolve this?

Edit mode,

select all vertices,

recalculate normals (CTRL+N)

sometimes helps,

Also setting the surface single sided helps (and do not impair rendering since that property is used only in game engine if I remember well)
