<node3d>.getCompositeAlpha(  
node = ''  
op = viz.OP_DEFAULT  
)  
node = ''
Name of subnode
op = viz.OP_DEFAULT
Can be viz.OP_DEFAULT to use the nodes default op mode or a combination of the following values:

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.

This command will return the composite alpha value of the node. See <node3d>.setCompositeAlpha for more information about composite alpha.
