Problem with Multi-Map Export

ZBrush Usage Questions
#1

I recently imported a DAZ3D figure into ZBrush and polypainted it. I then used Multi-Map Export to export diffuse color texture maps based on the polypaint. All of the maps worked fine, except the head map, which is a mess. (Please see screen shot.) Any guesses as to why the head map did not work?head_polypaint_export_mess.jpg

This is because the UVs overlap. ZBrush and MME can’t cope with that directly. (There’s a New From UVCheck option in the Tool>Texture Map sub-palette which will show you if your UVs are OK. If they overlap parts of the map will show red.)

  1. If the subtool has polygroups that correspond to the different UV tiles then you can skip this step. Otherwise you will need to press Tool>Polygroups>UV Groups.

  2. Turn off any texture that is displayed on the subtool.

  3. Turn on Polyframes by pressing Shift+F.

  4. Shift+Ctrl+click on a polygroup. This will show just that group. (If only part of a group gets hidden make sure the SelectRect brush is selected.)

  5. You can now create a map from polypaint by pressing Tool>Texture Map>New from Polypaint. Make sure you create it from the highest sub-division level - press ‘D’ if necessary to move up.

  6. Press Tool>Texture Map>Clone Txtr so that a copy of the map is put in the Texture palette. You can export it from there.

  7. Shift+Ctrl+click the background to show all the polygroups again.

  8. Repeat (4) and (5) for the next polygroup.

Thanks, Marcus. I will give this a try.
