I am trying to use Python inside of Houdini to recursively build geometry. One approach is using subnets recursively. However I then cannot render anything inside the subnet. Is there a way to display and render subnets of geometry that are themselves inside of subnets?

Another strategy is to use a container node which can hold both a Merge node and a Geo node. Problem is I haven't been able to find such a node so far!

Thank you!

Figured I'd add my solution. Not sure if it is really correct, and haven't used in a truly recursive manner yet. That said, I've been using Subnet Nodes to hold Geo Primitives (not Geo Nodes! careful!), and combining them into a single renderable node using a Merge. The Subnet can contain other Subnets, and the base Subnet can be converted to a Digital Asset by right-clicking → Create Digital Asset. Then you can sprinkle these around your network by hitting Tab → Digital Assets. If you later change the internal nodes, the asset may be updated by right-clicking → Save Operator Type (near the bottom of the giant context menu).
