Title: How to invert a face?
Post by: JunkerKun on December 10, 2013, 11:49:29 am

Well, the name of the topic says it all. Is there a way to invert a face? Not just a normal, but a whole face.

Inverting a normal is the same as inverting a face. Normals represent the direction of a face.

Weren't they for lighting calculation?
I just want to make a cartoon outline to be used in a game.

Generally vertex normals are used to indicate lighting, yes. Rest assured, flipping normals is the same as flipping a face.

For the toon outline effect you can flip the normals of the outer mesh or just create a 2-sided material for the outer mesh and have the front material transparent.

Oh. Okay, thanks!
