| submesh | The sub-mesh index. See subMeshCount. |
| applyBaseVertex | True (default value) will apply base vertex offset to returned indices. |
int[] Array with face indices.
Fetches the index list for the specified sub-mesh.
Each integer in the returned list is a vertex index, which is used as an offset into the Mesh's vertex arrays. See vertices and GetVertices. The layout of the indices depends on the MeshTopology of the sub-mesh. For example, a triangular mesh will return indices in multiples of three.
A sub-mesh represents a list of triangles (or indices with a different MeshTopology) that are rendered using a single Material. When the Mesh is used with a Renderer that has multiple materials, you should ensure that there is one sub-mesh per Material.
Call the method overload with a List parameter if you control the life cycle of the index buffer and wish to avoid allocation of a new array with every access.

Use this method overload if you control the life cycle of the list passed in and you want to avoid allocating a new array with every access.
