Quote - OK, I do have a question about exporting from DAZ Studio, not Poser, to prepare a obj to for painting in ZBrush (not morphs, painting!!).

Are you using a morphed obj? If not, why not use the original obj in the geometries folder?

If you are using the daz figures, I have a tutorial at my site byfivecat.com on. If  the tutorial is not clear, than please feel free to ask me specific questions.

As far as the export dialog:

Quote - So when I bring up the export dialog.

In the Basic tab there are 3 options:
Ignore Invisible Nodes
Use Bone Welds
Removed Unused Vertices

Which are checked?

Leave Ignore Invisible Nodes checked. Others unchecked.

In the Advanced tab there are 3 sections with sub options:
Swap Y and Z Orientation
Write UV Coordinates
Write Normals
Write Object Statements

Write Groups (section 2)
Use Existing Groups
Use Node Name(s)
Use Surface Name(s)
Use Figure Name(s)

Write Surfaces (section 3)
Write Material Library (sub options below)
No Maps
Collect Maps
Convert Maps (for Bryce)

Which of these areas should be checked and which sub options should be checked?

Write UV, write normals.
For painting, use surface names.

You do not need to write surfaces, so leave all unchecked.
