okay right so that's what i was saying before. i already knew you could do that but you can't actually layer things over grass, it's still gonna look like dirt or whatever underneath if you've got any transparency in the middle of the image. if you look at my heart planks behind my character, if i used the custom design tool for that it would look like dirt underneath the hearts instead of grass, so it's not actually using MY path design.
i think it should have been more clear in the game that what i was actually buying was the ability to layer designs OVER paths instead of actually using my designs as paths themselves.
