I have a simple sprite that I’ve centered perfectly in photoshop, and the pivot shows off-center. When I rotate the sprite, as you would expect, it wobbles around that pivot. This is a single sprite.
Thread looks pretty dead but I had this same problem today. Turns out, it was due to putting all the “problem” sprites into an empty game object (for asset organization in the scene hierarchy).
The problem was that I forgot to set the empty object to 0,0,0 before putting sprites into it. This caused the sprites to inherit the slight offset from the empty object. So, when I set the spites to 0,0,0, they were being positioned relative to the empty object’s home, rather than the absolute home of the scene.
Definite facepalm moment for me. Hope it’s a simple fix for anyone else reading this
