When you replace a path save (lets call the old path path1) with a new path (path 2) path 2 will automatically replace all instances of path 2 in game. (Im not sure about paintings and such since I have only needed to replace a path pattern)

Making brick patterns is SO HARD omfg, I wish you could edit QR coded patterns ;___; I want to be able to change the color of my bricks so I have to make them myself, including borders. Omfg. Okay but when I get done with them I'll make them all QR-able so others can use them too. But I mean I had to make a new character just to hold the patterns ok so this is a hardcore border and it's STILL not perfect, idk why I am having such a hard time with corners. Like, to make them repeatable, ya know? Just wow, it's way hard. So much respect for the people who have theirs available online in QR form. I just wish I could make them different colors and edit them yo.
