Topography in sculpt mode?

I made a sculpt with a multiresolution modifier on it. I can’t apply the modifier with the sculpt data – additionally, the sculpt data doesn’t show up in object mode. All I’m looking to do is overlay a topography on my work. Is this something I can do in sculpt mode? Does anyone know what I’m talking about? It’s a dire situation for me.

In the multi-res modifier there is a little gui box that says ‘preview’ by default it stays at 1, raise that to whatever level you wish to see it shown in the viewport. And there’s a button called ‘apply’ it applies it at that level.

You’re not doing this to bake are you?
