Trying to make Normal Map look good??

ZBrush Usage Questions
#1

Hello and thanks for your time.
No matter what i do to the normal map in 3dsmax, I can never get the nice and clean detail that I have in Zbrush on my model.

The mesh is fine, the displacement map is fine, but the normal map looks raggedy in certain ears (around ears and nostril holes), and even seems to create unwanted detail (creases, pinches, noise).

The map is inserted into a “bump map” shader in 3dsmax. Smoothing is on, Multiplier is set to 0.3. Bump value is at default 30. Increase the smoothenss of the mesh model using Turbosmooth just in help out with smoothing the contours. Rendering in MR

I just think there is something I am missing to make this look tighter.
Can you suggest a better idea or an idea on how to make the normal map look better when I rendering.

thanks, Lemon

can we see the image that you’re tying to render so we can see the problems?

thanks for the reply,

I have attached an of the full mesh model, and of the SubD=2 model with displacement map only, both from ZB, but rendered in 3dsmax.

So the fullmesh is how it is supposed to look. So far the displacement map image doesn’t look too bad. I had to use a SubD=2 because a SubD=1 would look to faceted, even with the DM.
But even in SubD=2, the nostrils edges are not as smooth as the full mesh, and some artefacts are on the lips.

I did not include the bump map because it was hideous, raggedy edges. I will experiment with this some more. I think perhaps my UV map has to be fixed somewhat.

any ideas on how I can get a better result with DM and BM??full_mesh_good copy.jpg

what level are you generating your displacement map at?
can I see the UVs for the head?
