Yeah, my apologies, I should have deleted the comment as I figured it out pretty much right after I asked. I was just confused and didn't realise the "corner mat" is the one that changes the turnbuckle texture image. All good now. Thanks again for the response and all of your creations and collections though!

Nope, no mods.

When you subscribe to an apron, mat, corner mats, or posts, they’ll download the next time you launch Fire Pro. From there, those parts are available in Ring Edit to make your own rings. The same goes for parts you make and place in the appropriate Decal folders in the directory Fire Pro is installed to - they’ll be available the next time you launch the game.

It would be great if we could upload whole rings to the Workshop so you wouldn’t need to piece them together in Ring Edit, but that’s the way it is right now.

Does this require a mod or something? Not sure how to add this to my ring edit.
