I have had this problem a number of times where the "shape" of the "body" of an objects physics does not match the image, even when I have it set to be the shape of the first image. I have uploaded an example where I have an object that is supposed to be shaped like an acorn, but the physics object is not matching the actual image but is off somehow. It looks a little bit to me like the physics body is the actual image upside down, but could be wrong about that ? Do anyone know how to fix this and what is wrong?
(You can spawn acorns by pressing the right mouse button)
