| properties | Material parameters to retrieve. |
| materialIndex | The index of the Material you want to get overridden parameters from. The index ranges from 0 to Renderer.sharedMaterials.Length-1. |
Get per-Renderer or per-Material property block.
The retrieved properties are stored in the property block passed in through "properties". If no properties are set, the property block is cleared. In either case the property block you pass in is completely overwritten.
If you provide a Material index, only the parameters of that Material are retrieved.
