I have built a complex materialX network inside a Karma material builder and i promoted the parameters as subnet inputs so they show up on the material builder parameters UI.
There are a lot of promoted parameters so I organised the exposed parameters using collapsible folders.

I want to use the Edit_Material_Properties LOP to generate child materials from my master material.

When I keep the material builder as a regular subnet, and I want to edit the generated USD material using an Edit_Material_Properties LOP, the UI i created and the folder structure is intact.

But if I convert my subnet into a HDA, and i load the USD material generated from it into the Edit_Material_Properties LOP, the folder structure is not recognised and all the parameters are listed in a very unorganised way. Also the folders and toggles appear as float or int parameters.

Is there a solutions to this, so that i am able to keep the same UI and share the Material builder I made as a HDA?

Cheers
