ROBLOX head mesh shading problem

Support Modeling

I exported this model of a player character from a game called ROBLOX. What I noticed when I set the shading of the meshes to Smooth was that there was one particular section of the head mesh that wasn’t shaded like the rest of the head is.

You need to select all verts in edit mode and perform a “remove doubles”.
