Ahh, here's the thread...

Dan,  as Robert mentions above, you should use Riptide if possible.  This will let you set up all of your groups and materials inside C4D before you export.  It's generally MUCH easier to set up groups in C4D where you have everything in componant parts in the Object Manager (OM).

If the Eyes are separate meshes in C4D and you have Riptide installed...

1. select the left eye mesh in the OM  (heirarchy list on right side of screen).
2. select all polygons of the left eye.
3. create new selection and name it 'leftEye' (or whatever Kate's left eye group needs to be named).
4. over in the OM, right-click on the left eye mesh and add a new tag... "Riptide Tags - > Group"
5. when the Group Tag dialog opens, (or double-click on it later on, to open it again) look for 'leftEye' in the left-hand 'Available' column and move it to the right-hand 'Selected' column (select the leftEye entry and click on the -> buton beside where it says "Available").
6. repeat steps 1->5 for the 'rightEye' mesh.
7. repeat steps 1-5 for any other disconnected/separate meshes.
8. if you have any meshes that have more than one 'group' in them, just create selection tags for each group of polygons, using the exact/case-sensitive/correct naming that Poser is expecting ('hip', 'abdomen', 'chest', 'neck', 'head', lCollar', 'lShldr', etc.), then just add ONE 'Group Tag' to that mesh, but when the dialog opens, move all of those 'Available' group selections to the 'Selected' column (don't add any material selections you might have set up - just the group selections).
9. Set up all of your material zones... select the desired polygons, create a new selection tag, add a material to the mesh in the OM and restrict it to use the named seletion you set up.
10. Make sure all of your meshes are UV-mapped (Riptide expects the mesh to have UV coordinates).
11. When you're ready to export, go to the Plugins menu and select Riptide->.Obj Exporter.
12. enter a filename.
13. on the Riptide Dialog, make sure the following options are enabled/checked:

+ Export Faces

• Reverse Faces
• Export UV Coords
• Export Materials
• Export Groups
• Export Regions (optional... if you have a Region Tag set up with some UVMapper regions set up like the Group Tag is done).
• Sort by Material (this helps de-frag the .obj file, so it loads faster)
• Group Tag Names

...if you set up your mesh(es) as described above, then thos are the only options you need to have enabled.. everything else on that dialog can be disabled.  Now when you export (or import, for that matter) using Riptide from now on, all of those groups and material zones will be preserved.

When you load the model into Poser with all the groups already set up (assuming you used the exact naming needed), you won't have to mess with Poser's Group editor at all.

Cheers,

• Keith
