| indices | The array of indices that define the Mesh. |
| topology | The topology of the Mesh, e.g: Triangles, Lines, Quads, Points, etc. See MeshTopology. |
| submesh | The submesh to modify. |
| calculateBounds | Calculate the bounding box of the Mesh after setting the indices. This is done by default. Use false when you want to use the existing bounding box and reduce the CPU cost of setting the indices. |
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.
