All you have to do is frame your sculpture, open up the ZBrush Compositor, and select 'Create Toolbag Composite'
This will send a series of BPR passes and a simple UV plane into Marmoset Toolbag that looks exactly like the mesh in ZBrush.
Once in marmoset, you can take advantage of all the cool rendering tools to produce a more appealing render for your 3D sketches...
This is a super quick and powerful way to produce concepts without the need of exporting complex meshes or even having UVs on the mesh. Ultimately what the ZBrush Compositor produces is a series of maps, including the Depth of the mesh to displace a low res plane.
