Sets the index buffer for the sub-Mesh.

A sub-Mesh is simply a separate indices array. When the Mesh Renderer uses multiple Materials, you should ensure that there are as many sub-Meshes as Materials.

SetTriangles and ::triangles always set the Mesh to be composed of triangle faces. Use SetIndices to create a Mesh composed of lines or points.
