Hey all. So I’m trying to use Zmapper to generate a normal map for this head, but the head isn’t showing up in zmapper. The problem seems to be an issue with the uv groups. I’ll attach a picture below, so you can see what I’m talking about. I was wondering if there is a way I can just delete that uv data, and just use guv tiles instead. Or is there another fix you might reccomend? Thanks!
tool>texture>disable UVs
tool>texture>enable UVs
tool>texture>GUV tiles
Actually, it’s easier yet. Simply assign a blank texture to the model that is the size you wish to paint and then press Tool>Texture>GUVTiles. ZBrush will replace the old UV’s with the new ones. No need to disable and then enable them again.
If you don’t apply a blank texture to the model before pressing GUVTiles, ZBrush will calculate the mapping based on a 1024 size. That can then create problems if you create your maps at a different size.
