I'm probably just going to go with using Snarlygribbly's SceneFixer to make an INJ and REM file.

I had never used that feature before... but that seems to be working pretty well.

The rendered figure there is a new blank M4 (not the CR2 I sculpted onto) with the morph loaded from the INJ pose I made with SceneFixer.

I checked the INJ file output in TextEdit and it is only the deltas for Neck, Head and Head-Children body parts that are in there.

I think I'll try and figure out how to sculpt a displacement layer next... while I let the poly sculpt sit a while and see what I notice about it that I need to change.

If anyone has any comment or suggestions regarding the sculpt, I'd much appreciate any input :-)
