### Remarks

The [Mesh.CombineMeshes](/engine/6000.7/script-reference/unityengine/mesh/combinemeshes.md) method uses this property along with [CombineInstance.subMeshIndex](/engine/6000.7/script-reference/unityengine/combineinstance/submeshindex.md) to identify the mesh data to copy into the combined mesh.

The default value of this property is `null`.

To combine a mesh, this property must reference a valid, non-null mesh. Furthermore, the mesh must be CPU-readable.
