My working V3 is 256MBs, and my M2 is 100MBs.  The other day I decided to make each .PZ3 as small as I could get it without losing quality.  

V3 went really well I was able to run CollectSceneInventory.PY, and .RAR the result to the tune of 12MBs!

M2 has been a totally different story though.  I'm still stuck around the 50MB mark, but at least I know why.  It's got to do with two, 25MB and 10MB, .BUM files I have for the Head and Body!

What are some ways to get around these, are there alternatives, can I shrink the file size, what is a good editor?
