Does the tile preview and tile palette show up? The tile preview should be drawn with the same code as the work plane, so it would be really weird to me if the preview is drawing but not the work plane.
Just to make sure, what are the Sprytile workflow settings for the work plane?
Since you mentioned tile preview and tile palette I thought I would see if they would show up if I added a tileset. It seems the work plane doesn't show when you don't have a tileset loaded. I was just getting used to the workflow of the geometry without using one, it appeared the moment I added a tileset. Everything is working fine now so thank you so much! :)
