I have multiple Redshift materials (defined as a database) that I'd like to load into the application and show to the user in a GeDialog.

I have successfully loaded the database into the application, but it is not clear to me how to traverse the database such that I am able to build up a tree view structure that can be used to navigate the various catetories/assets in the database.

Using the GetUserPrefsRepository function, I can search for a given category or asset - but only if I know it's ID ahead of time.

If I know the top level category, is it possible to traverse the repository from that point and build up a TreeView to represent those assets?

I would like to create a C++ plugin that is able to load textures from a directory and allow the user to drag/drop the textures into C4D for use in creating materials.

Is there a document that describes the best practices for accomplishing this task?
