If you want to use my designs created by others, you can't use them unless you subscribe to Nintendo...😭 If you can create your own designs, you may not need to join! However, the road at 1:12 and the [simple panel] design at 1:29 use the default designs in the game. If you create it without using My Design, it will lack realism, but I think you can create it even if you remake it with the default design!😊
