How to rotate the capsule component (or add a new capsule component) for my swimming character?

[Noah_Z]

I want my character go swimming and I just created some test swimming animation for this character.

But it seems that the capsule component cannot be rotated when swimming, like this:

I want to add a new capsule component and attach it to one bone of my skeletal mesh, and set the collision type to BlockAll, but it does not work at all.

How to handle this problem?
