For a quick fix I came up with the obvious although the edges are not exact, stone tex will eleviate some of that and some post work for a finish product. Works for a busted head, and I don't imagine it'll be the main focus of the pic. I'm sure with more tweaking it could be a closer fit. Hey!, it could even be a good start for exposed gray matter. :) import poser head, booley the head with a stone or cube. Ungroup,duplicate stone, re-group head & stone 1, slide stone 2 to side. Create sphere,center with head, resize as close to cranium as possible, slide sphere under stone2. booley sphere & stone, group, slide bact to cranium. hope this helps ICM
