FlipMesh:Void mesh:Int32

Parameter	Mode	Type	Default	Description
mesh	In	Int32	required	Mesh handle.

Description

Turns every triangle of a mesh around so that it faces the other way. Triangles are only drawn from the side they face, so a sphere made as a sky has to be flipped to be seen from inside. Flipping also turns the lighting normals around. If you need a mesh visible from both sides, copy it with CopyMesh, flip the copy and merge both with AddMesh, or just draw both sides with the 16 flag of EntityFX, which is cheaper.
