Expanding colision surface

Hello people!

I am having a small (at least I think it is) problem with collisions and surfaces.

I have a rigid body (ice cube) falling inside of a collider body (glass) with a static mesh shape and also a taper deformer.

Is it possible to expand the collision surface of the glass after applying the taper deformer? If not, it makes no sense to have it because then the ice cube cannot interact fully with the glass.

I uploaded a picture of my scene.

Thanks

Sorry for the late reply. It worked perfectly. Thanks
