Hi, it seems like
gives you back the source node (e.g. “sourceGroup0000_source”) and not the group node (“sourceGroup0000”) so when adding them to the stack like this it warns you that you didn’t add the complete group.
So also getting here the node groups first and adding the complete source group to the stack should get rid of the warning:
rv.commands.setNodeInputs(stack_node, [rv.commands.nodeGroup(src2_node), rv.commands.nodeGroup(src1_node)])
