I've been using Hexagon to make a full body morph for a Poser character. Did a bunch of single group tests before starting. Everything looked good. No scaling issues. No reordering of vertices. Morphs worked fine back in Poser. So I started to work on my little project which requires working with a bunch of groups at the same time. "Tweak" with soft selection doesn't work across groups in Hex even when you've put them all into one group, but that's ok, translate does so I made do with that. After a few hours work I realized that every time I saved it seemed to take quite a while to finish so I checked the file size and discovered that my saved file was more than ten times the size of the original obj. Note that I'm only moving vertices around and not adding any new geometry. Dynamic geometry has been off the whole time. Did several little tests to see if maybe I had a setting wrong and same result, saved file more than ten times bigger than the original. So, just for the heck of it, I opened the original obj and immediately resaved it without doing any modeling at all. File size again was over ten times as big. Grr. Note that this is on a figure with about a dozen groups (I had deleted head, hands and feet). Then I opened each file in UVMapper Pro and the stats for each were identical even though one file was over ten times bigger than the other. Ran Spanki's Stomp utility on the saved file and it made it even bigger. Then I did another test. Opened a similar size obj that had only one group and resaved. This time the saved file was actually about 20 percent smaller. So, the problem at this point 'appears' to only happen with figures with several groups. Anyone know what's going on here? Is there a setting somewhere that I'm overlooking that could be causing it? I'm guessing that upon saving Hex is creating a bunch of redundancies (related to grouping?) that don't show up in file stats. Maybe there's a utility that can clean them up? My little project can't be done in Hexagon if I can't figure this out. Thanks for any help.
