Sprite Animation changing rigidbody collider size

Hello, I have a sprite animation whose frames vary in size. However, I want the box collider attached to remain the same size on all frames. I noticed the Rigidbody component seems to be changing the size for those frames, however. Is there a way to prevent this?

pick up the gameobject, open the animation window (ctrl-6 ? ), and try to delete the keys, wich change the rigidbody ?

The only change is the sprite, so I don’t think I can do that.

are you sure, that the collider changes his size ? The sprite and collider should be independently. You can change collider through animationkeys or script. Maybe there is other way, but i dont know them. Try delete collider and add new one.

Yeah, I have only a rigidbody2d, collider, animator, and sprite, and during some animation frames the collider changes size.
