I'm not sure what's going on here. I have a cube which I have turned into a rectangle; it's a child of a plane which is the "ground" so that they share rotation (this is a pinball table).
To create these cubes, I just used the create => 3d shape => cube/plane option. No packages are used.
The issue is when I rotate the rectangle, the collider visibly becomes wrong.
This is before rotation:
This is after rotating on the y axis:
The collider does seem to rotate, but not at the correct amount. Can anyone shed some light as to what's going on here?
Here's the inspector and hierarchy:
I also tried making the plane a cube, it didn't change anything.
