| indices | A list of indices to populate. |
| submesh | The sub mesh on this instance. See subMeshCount. |
| applyBaseVertex | True (default) value will apply base vertex offset to returned indices. |
Gets the index buffer for the specified sub mesh on this instance.
Each element value in the returned index buffer refers to a vertex index, which can be used to index into the results of other accessors like vertices and GetVertices. The layout of the indices depends on the topology of the sub mesh. For example, a triangular mesh will return indices in multiples of three.
A sub mesh is simply a separate index buffer. When the mesh is rendered using multiple materials, you should ensure that there is one sub mesh per Material.
Call the method overload with a List<int> parameter if you control the life cycle of the index buffer and wish to avoid allocation of a new array with every access.
