Hi,
The last time i scanning my friend, but final efect isn’t good.
I fixed mesh in geomagic wrap and the next step was tried fix texture in zBrush.
I colorized model with polypaint and spotlight, but now I can’t export texture.
Its way to export UV map from this model?
I don’t want starting from begining.

Hello @Fr3dson
Be sure to upgrade to the most recent version of ZBrush. This is free for registered users, and older versions are missing lots of features and fixes.
You have to clone your texture to the texture palette in order to export it. So press “Clone Texture” in the Tool> Texture Map menu, then go to the main Texture palette and export it from there at the desired settings.
Or, use Multi Map Exporter.
The issue with the color is likely due to an issue with your UVs.
Good luck!
