Options to control the optimization of mesh data during asset import.
| PolygonOrder | Optimize the order of polygons in the mesh to make better use of the GPUs internal caches to improve rendering performance. | 
| VertexOrder | Optimize the order of vertices in the mesh to make better use of the GPUs internal caches to improve rendering performance. | 
| Everything | Perform maximum optimization of the mesh data, enables all optimization options. |
