Hi guys, so i’m trying to make an object for my little game and it’s shaped like two rectangles but one is slightly rotated,and they should parent&child, but every time I try to rotate the child alone, its shape deforms and I have no idea why.
If you guys have any experience with this issue and could give me solution it would be much appreciated 
This is a scaling issue. The parent is scaled, thus makes the child all wonky when its rotated.
The best thing to do is create an empty gameObject in the scene with 1,1,1 scale - named “Base” (or whatever you want). Then put both of your other gameObjects under this parent (but not under each other). You may have to re align them, but probably not.
Now you can scale them individually and they wont be affected by the parents scale.
