Thank you for the quick reply! Seems like it is just a skill issue! I suppose the biggest problem was ive tried even blocks, but this way makes quite more sense :D
No worries haha! Which engine do you use? If It's free I could try to 9-slice it in the engine you use and send a little tutorial, just to make sure everything is correct
I am actually currently around in Roblox Studio, thats quite new for me, so I suppose thats where the problem came from. Though, good news, I have managed it myself! :D Thank you very much though - I love the design!
