I was playing around with some Python viewstates for a HDA in Solaris. But I cant figure out a good way to work with setting transforms for specific prims. I want to make an interactive layout tool where my idea is that you select the prim and then move it. So the prim i write to needs to be able to change. I tried setting parm values for an edit lop inside the HDA with the python state, working on the USD layer directly, hooking into transform primvars. But I keep running into issues regardless of my approach. My only idea remaining is to programmatically create separate transform nodes for every prim when selected, but that seems inefficient
