Collision block characters but not nav mesh?

I want to have a big cube character which can move around on a nav mesh, but also make it so that players can step on top of it.

Here’s my cube character

When I set the collision to block pawn, the players can step up on the static mesh cube fine. But then the cube starts to block the nav mesh, which prevents my cube from moving around.

Character can Step Up on is set to true.

Any advice?

Thanks

Boom. In the drop down you can select Can Ever Affect Navigation to get the best of both worlds.
