you  can use  free UV Mapper  if  you  have a direct relationship  of mat  zones to  what  your groups  have to  be.

in Lightwave.......  create  mat zones......   label  them   anything  you  want so  that  they are distinct  - "A", "B",  "C" ...etc.

then  bring the model  into  UV mapper - generate a UV map....then  click   EDIT....   TILE  BY   ...MATERIAL  ( with  "gaps"  checked ON)

and the map  will  change to showing  all of the different  mat  zones  from  Lightwave  neatly seperated.

then  just  select  each  section of  mesh one at  a time  and  do   EDIT ....  ADD TO ....  GROUP

and name your groups accordingly  as you  create them.

spit your new model out of UV mapper  and  you  are done.

the extra added  bonus  is  you  have also  taken  care of UV mapping your model  while you  were at  it.

also ....  AFTER  you  have  tiled  by  material  and  AFTER  you  have  put the different materials into  diff groups -  you  can  REGENERATE UV  maps  of diferent layout type ...and you  do  not lose your groups
