how to enable node and all children
I've created a number of on-the-fly objects (e.g., parent=viz.endlayer() and child=viz.endlayer() each with their own custom vertices), some of which I then link to each other with the command:
child.parent(parent)
I would then like to enable lighting for an object and all its children. I thought the command:
parent.enable(viz.LIGHTING)
would do this, but it didn't seem to work. So I tried:
parent.enable(viz.LIGHTING,'',viz.OP_TRAVERSE)
or
parent.enable(viz.LIGHTING,'',viz.OP_OVERRIDE)
but those also didn't work. I guess I misunderstand how to do this. Could someone please help?
