| Op modes | |
| viz.OP_TRAVERSE | When performing an operation on a node, traverse the entire subgraph and process all subnodes as well. This is the default value. | 
| viz.OP_OVERRIDE | When applying attributes, have them override attributes of subnodes. | 
| viz.OP_ROOT | When performing an operation on the node, start at the root transform of the node, instead of the model. Processing the root will include all child Vizard nodes. |
