Attached Link: Lothlorien Poser mat test

     What version of Poser are you using?  P8 & PP2010 had unpredictable issues with OBJ import.  However, my experience was that either pieces were missing or the OBJ import failed *in toto*.  The only problem I had with Poser dying on OBJ import turned out to be the *Catalyst* utility for ATI Radeon video cards - something to do with Open GL.

     The OBJ import problem was fixed with P9 & PP2012.  I have thrown some hideous geometry at them with not a single import fail.  This pair of trees was one of my test OBJs.  It has many (strictly convex) n-gons, and the leaf n-gons are non-planar, yet P9/PP2012 imports it and renders it correctly.

     The hotlink at top is the Poser render of this model.
