Because Max can export smooth-groups to an obj-file and Poser is able to understand this, I've tried to find something about smoothing groups in this document: http://local.wasp.uwa.edu.au/~pbourke/dataformats/obj/

Seems that having a group tagged with "s 0" stops smothing this group (e.g. anything following until "s 1" occurs).  I don't have Max, so I'm not able to explore an obj-file written by Max.

But if this is correct, a python-script can alter an obj-file while identifying named groups ("g noSmoth") while adding "s 0" right under this "g"-entry. All other group definitions needs a following "s 1" if I understand the document correctly.

(untested hack to get the point):

fh=open("original.obj")
fhout=open("copy.obj","w")<br></br>for line in fh:
  print >> fhout, line<br></br>  l=line.strip().split(None,1)
  if l[0]=="g" :
    if l[1] == "noSmooth":
      print >> fhout, "s 1"
    else:
      print >> fhout, "s 0"    <br></br>close(fhout)
close(fh)<br></br>
