|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 sub-mesh 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.|
|baseVertex||Optional vertex offset that is added to all triangle vertex indices.|
Sets the index buffer for the sub-mesh.
