The spinning render is working at least.
I must admit, I'm not a big fan of the recent changes to the model editing.
Each formerly fast and easy step somehow got many many superfluous steps added to them.
Having several additional clicks just to view the model.
Navigating several drop down menus multiple time instead of having a simple and well overseeable list from the materials you'd like to sell.
It just wastes quite some time and makes previously easy tasks more complicated without any apparent benefit.
If it's loading times, I'd much rather have it load one second longer once and have a nice list instead of manually searching for materials from a drop down menu several times over and over.
