Applying bump maps to objects

So i’m just curious on if anybody knows how to do this. But I know that you can sculpt in zbrush then make bump maps from that and use it. But can you do the opposite and create a bump map in different program, Import that bump map in to zbrush then apply its properties to the actual mesh. Is this doable?

If it is height-based, you can load it as a displacement map.

but wont i lose a lot of quality, because displacement maps have less color variation.

If it’s anything other than a proper displacement map, you’re pretty much going to be losing quality either way.
