Instance Property vertex Descriptor
A description of the format and layout of the mesh’s vertex buffers.

Read this property to determine the vertex data format to be used in rendering the mesh. By writing a new value to this property, you can restructure the vertex data in the mesh.
Changing a mesh’s vertex descriptor can be an expensive or destructive operation. Depending on the differences between the current and new vertex descriptors, reformatting may copy up to the entire vertex data into a new structure and delete any vertex data corresponding to attributes that are not present in the new vertex descriptor.
