Zmapper-normal map error help?

[andycce]

Hi,
I’ve looked for an answer to my problem, but nothing looks like this.

I have an object that I’m trying to create a normal map for.

I created the UV’s externally in UVLayout, and there are two distinct UV regions.

I used UV-Polygroups to separate and hide the geometry. I created a 2048 texture for this region and used Zmapper to generate the normal map, and I just get these odd triangular deformations. I’ve included screenshots of the sculpt and the result from Zmapper

I know my UVs are still good, and I was able to generate proper multi-displacements

I’m on a PC

Can anyone clue me in?

Thanks in advance.

Hiding the geometry doesn’t work in ZBrush 3. You need to split the geometry for the different UV regions into separate subtools before you can use ZMapper with good results.

Many thanks for the reply.
