I don't think it would help much.  The figures would still have material zones in their OBJ files, and Poser would still try to create material nodes corresponding to the zones when it loaded.

I did a quick test on a figure that I happened to be working on....  It's a 'live' schematic symbol, with 48 separate material zones and separate controls for each, so it can show current flow by moving colors through the zones.  With all of its node paragraphs and dials, it takes 10 seconds to load.   I then stripped out all the material stuff from the file, reducing it from 760 KB to 12 KB.   Seems like it should be faster?  Only a little bit.  Takes 8 seconds instead of 10 seconds.

The problem is that Poser will always build the nodes internally whether the file specifies them or not.
