Edge Radius of BoxCollider2D does not scale with object

Physics

I don’t know if this is a bug or intended behavior, but it tripped me up.

The Edge Radius appears to be in world units, regardless of the scale of the object it is on.

This does not follow the behavior of the related fields Offset and Size, both of which are affected by the scale of the object.

Does anyone know if there is a good reason for this, or is it just a bug?

edit: this is in 5.6.0f3

It is by design and this is the first time this has been asked TBH.

The problem with scaling is that the edge radius has to be uniform, it cannot be scaled differently in X and Y. If it were scaled, it’d have to be in a similar fashion to the radius of a CircleCollider2D which uses the maximum of the XY scale.

It can certainly be added as an option.
