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?

The following should work:This will perform the operation to include all children Vizard nodes. You can also place all the objects underneath a group node, which will automatically perform all operations on its childeren, without needing to specify the op mode.

Thanks! That works wonders, and the default behavior you described when objects are collected under a group node explains a subtlety I didn't previously understand: that enable(viz.LIGHTING) was changing all children in some of my objects (i.e., those in a group), but not for others (i.e., those not in a group).

I thought I'd read the documentation pretty thoroughly but I didn't see anything covering group nodes - I learned about them through another forum post. I would have liked to see this documentation in the "Reference"->"3D models" section. Can I suggest that this be added, or if I overlooked the discussion on group nodes, can you point me towards it? Thanks again and in advance!
