Syntax

EMeshResult RemoveTriangle
(
    int TriangleID,
    bool bRemoveIsolatedVertices,
    bool bPreserveManifold
)

Remarks

Remove a triangle from the mesh. Also removes any unreferenced edges after tri is removed. If bRemoveIsolatedVertices is false, then if you remove all tris from a vert, that vert is also removed. If bPreserveManifold, we check that you will not create a bow tie vertex (and return false). If this check is not done, you have to make sure you don't create a bow tie, because other code assumes we don't have bow ties, and will not handle it properly
