public int firstVertex { readonly get; set; }
Remarks
Together with SubMeshDescriptor.vertexCount, this defines the range of vertices that are possibly used by this sub-mesh. These values are important for any CPU-based mesh processing that would be done, for example dynamic batching or CPU skinning.
The SubMeshDescriptor.bounds, SubMeshDescriptor.firstVertex and SubMeshDescriptor.vertexCount values are calculated automatically by Mesh.SetSubMesh, unless MeshUpdateFlags.DontRecalculateBounds flag is passed.
