As a guess. >snarl1 has 7929 vertices. when i import THAT as a morph >target, i get 'wrong # of vertices.' Although the vertice count is correct between export to/from Poser/RDS extra groups may have been created, splitting up the original group into smaller groups. A lot of 3D apps (incl RDS) do not read groups/usemtl statements (in .obj format) that share edges thus create new groups, but this adds extra vertices (duplicating the shared edges). If you are welding identical vertices on import to Poser this will cover this up but the extra g statements will remain. There is much more to this but not sure of your exact procedure.... Naming as polygons on props tends to cause this later on down the line. Groups within groups. >if i weld the stuff in ray dream (the new group does appear >as another polymesh), i get 6779 vertices, and that is the wrong number, too. The weld feature in RDS is not as precise as the weld identical vertice on Poser import command. RDS will weld more than just the identical vertices together even in its minimum range as Poser figures are so small in scale. Especially around detailed areas such as eyelids and lips, thus generating fewer vertices. Simply weld on import to Poser.
