Yes. This is especially useful when a rendering engine does not support subpixel displacements. What you would do is sculpt your high resolution model and create a normal map for it. Save the tool so that you can come back to the high resolution version later if you need to. Now switch to a medium subdivision level and delete the higher levels. Create a displacement map. You’ll now have a displacement map for medium frequency details and a normal map for high frequency details.
so would you use the normal map and displacement map at the same time on the low res model? I find this very interesting
I am also really interested in this…
Also, does anyone know how to increase depth or sharpness within the map, when generating a normal map in Zbrush( appears to be no settings )?
If you use Maya’s transfare surface info ( default settings 6.5) from the same model exported at highest rez, the normal map that is generatrated appears sharper ( has minor artifacts though across seems )
Is there a setting, or a way to control the depth of the map in zbrush?
I note that there are settings for the displacment map generation…
yes i would love an answer to the question above… i get very pixelated polygon-looking normal maps … iw ould love to get a nice fine detailed one… i mean i export them at subdiv lev 6 and make my maps 4096 … still no difference. thanks.
If my renderer supports per pixel poly displacement, is there any advantage in using this method? I’m not sure, but I think normal maps are actually more effective with fine details than displacement (mostly because I never got displacement maps to work perfectly actually) but I have no problem with someone clarifying it for me! :lol:

Prevenge Hi
Maybe you should try the Zmapper plugin for Zbrush,it really makes a big difference on the quality of the normal map that extracts.Also try to check the smooth normals option in the plugin to smooth out the faceted look of your map.Please forgive my poor English.I hope this information help solve your problem.
is it possible to use the normal map and displacement map at the same time on the low res model? I find this very interesting
