I am considering Pro Pack for its 3DSMAX integration. But My biggest question... Will Max dynamic plugs work, rather can I use Max modifiers "on the fly" ? PHI factory works fine for me now, and the Habware import export .OBJ Max plug-ins are simple enough. So if all I can get out of PPP is easier character generation I may as well save my money. I hope my question is as clear as I think it is...

Have not tried dynamics yet, but modifiers, space warps and stuff work just fine... BUT the PPP plug is not really usable in serious productions. Often you open the max file, material IDs are redistributed, renaming or editing Materials and IDs is rather unpredictable. I suggest using poser for stills or animatics and stuff. As soon as you got the figure you want, export and use character studio. A little more work for the set-up, but much more stable and convenient in the production pipeline. I am not surprised there is no max-plug for poser 5.
