I have been working on a small mesh editor inside the Unity editor for minor modifications on meshes and rapid prototyping. I have a working gizmo system to draw handles and I can move vertices just fine. (After all, they are just Vector3s, I just set a new position) My problem is that I have no way of moving triangles (indices). I think that the correct way to do it is to just move the vertices that "make" the triangle and that would be easy if I had a way to actually get the corresponding vertices from the int unity's mesh contains. Any ideas? Thanks in advance.
