Pretty self explanatory I think. The reason I am wanting to do this is to work around the object port object operator bug.
Basically, I want to just add the port myself, then query the already made node so I can access it's port info. I tried all the selection methods I can think of, but it seems C4D doesn't treat nodes as objects. Thanks for the help.

Hi Rick,
You have to first get the XPResso node master from the XPresso tag calling XPressoTag.GetNodeMaster().
Then to get the root node use GvNodeMaster.GetRoot() returning a GvNode, which is a subclass of GeListNode (so you can navigate the node tree with node.GetNext(), node.GetChildren() etc.). -

So I tried to use the .GetChildren() and the other GeListNode stuff, but instead of getting the one node that is in there, I get an empty list or just a None. Figured i would post my code so maybe it will make it easier. I am currently testing it with just a cube at the top of the Object Manager with the said xpresso tag with the object operator inside already set up, along with a couple of spheres below to test the list function. Thanks for the help.

and not a GeListNode member, you have to call it from an actual GraphView node. edit : and please
use a monospace font to post your code or the code, /code tags. -

THANK YOU! I just realized it was Gv NodeMaster, and not Get NodeMaster that I needed to use to get the root node. I need to pay better attention to these things. Anyway here is the final code snippet if anyone is interested. Thanks for the help everyone.
