Oh yes, great place to start. Many people are saying David has been overlooked. Find the SnowSultan template guides (here in free stuff or at the Daz forum). Not sure if there is a David specific, but the M3 one will work just as well I think. P4 uses .bum format for bump maps, Poser Pro Pack uses .bum or .jpg for bump maps. Poser 5 - I'll leave that to someone who owns it to answer :) Pdxjims is right. Go and buy a terrific photorealistic texture (Morris or Dalanise are my personal recommendations) to get a feel for how it's done. Most importantly ... good luck :D
