I have not tried making a blank template item and changing solely the visual resource ID. Not sure, but is that any different from what I have tried? Which is, I have done create new item from template of the scenery I wanted, so some options were auto-completed for me. I noticed it left out the AI bounds, the physics resource, and the mesh resource because the base scenery did not have any (one of the decorative curtains) for reference.
In either event, I'll try it when I get some time. Thanks for the input
