I have modeled and textured a pair of shoes. As per a tutorial I learnt that for areas that share a similar texture the UVs can be placed one on top of the other because the texture would be the same. So that’s what i did, two shoes sharing a UV space, placed one on top of the other. However now that I have sculpted it in Zbrush I cant seem to be able to get a neat displacement map or normal map.
How does sharing UV space work? Or is there something I am doing wrong?
