It's in the blb. Not the cs file.
The UV Coords most likely.
Alright, I looked at the UV Coords and found that there is a top, bottom, north, east, south, and west parameter that each have a different combination numbers like this:
1 0
0 1
0 0
-1 0
Idk how to arrange those numbers to fix the texture size lol, and even if I did, I would need to change a minimum of 132 blb paramaters to fix every brick in the pack.
So what are anyone's solutions to this?
