heres a website on obj specifications http://www.martinreddy.net/gfx/3d/OBJ.spec

 

Note that obj tends to be an exchange format which may limit what can be exported from the native application. For example Lightwave and 3dsmax both have attributes that dont transfer in an obj export.

 

For Poser my workflow is

1. create and group the item and save as a layered Lightwave file.

2. Collapse the layers and export as obj.

3. Import to Poser (or use phi for figure) .

4. Fix rigging, add morphs, set materials and save as a Poser prop or figure.

5. Fix the obj file reference in the pp2 or cr2 file.
