Hey,

just trying to create a group parameter on a subnetwork - later to be an hda.

Seems i rarely use groups as parameters because i can't seem to get this to work. I made a video here, showing that if i drag the group filed onto the paramter window it creates but errors when i try and select.

Any ideas?

Error says argument of type 'NoneType' is not iterable

Thanks

You are trying to use the Attribute Wrangle's button to select. This button has unique functionality tied to the node which is not imported with the node's group parameter.

You can look into using Python Viewer States if this exact functionality is what you are trying to achieve, otherwise I would suggest using a standard Group node, which will create a point/vertex/prim int attribute called @group_, which you can query or reference in the other nodes.

Hey thankyou,

of course makes sense, didn't think of that. I'll set it up instead with a normal group node.

Thanks very much
