Gets a value indicating whether or not this mesh face is considered to be valid. Note that even valid mesh faces could potentially be invalid in the context of a specific Mesh, if one or more of the corner indices exceeds the number of vertices on the mesh. If you want to perform a complete validity check, use IsValid(int) instead.
Gets a value indicating whether or not this mesh face is considered to be valid. Unlike the simple IsValid function, this function takes upper bound indices into account.
