The loom is a python script that is associated with matmatic.  BB took me very patiently through the installation and use of matmatic over at RDNA (look up "Poser > node cult" to find the thread.  It is well worth the trouble and time to learn ... it also helps you to understand the workings behind EZmat.  :)  I hope this helps.  I did do all of that ... just to be able to use the loom, by the way.

P.S. The other features of matmatic are ... amazing as well.  You team matmatic with EZmat and you can do great things in the Material room.
