Hi,
I have tried to get some detailed geometry applied systematically over a pillar model as a whole using uvs and applying a displacement map from rock materials I found online. With whatever approach I take, I end up with a lot of abnormalities in the resulting model that are pain to fix, and I was wondering if there was a better way to do this. I am aiming to test that geometry for 3d printing purposes, which is why I don’t want just a displacement map, but actual geometry.
The two approaches I got so far are as follows:
- I simply unwrap uvs in zbrush and apply the displacement map directly, which generates obvious issues at the seams:
I then fix the seams by using a combination of morph, flattening and smoothing and xtractor to copy over some geometry from the parts that turned out better. The result is somewhat satisfying but tedious. Yet, this approach seems to work best for me so far because I get crisper details from my displacement map as opposed to the second approach.
- I export the pillar model into Substance Painter instead, and fix the seams by blending heigh maps and other methods there. I export back the mesh and displacement into zbrush.
When I use Disp on for the preview, it gives the correct output :
But when I click apply for the displacement map, I get the following:
I can then proceed to fix the abnormalities, but I’ve come to notice that, actually, the details of the sculpt from the first approach are much crisper (possibly because I butchered the height map in Painter when I tried fixing it… guess I lost control of actual displacements there).
So, generally speaking, I am trying to find a solution to applying displacement maps in zbrush to get detailed geometry systematically laid out over a model. In particular, I like to produce complex fine details and noise from materials found on the internet or by using Substance Designer to define displacement maps. I just a more efficient way to get this displacement laid out correctly on models as geometry if that is possible.
Is there a better way to approach this problem? What are your procedures when it comes to fixing seam issues resulting from displacements?
I am looking forward to hearing about how you would tackle this.

Simon
