No matter which figures you use, any morphs with the same internal name (the name on the dial doesn't matter) will crosstalk in Poser 4. If Victoria 2, Stephanie and Michael all have a morph named "ZLURB", but Victoria 1 and the Millennium PreSchool Girl do not, when you set the 1st figure's "ZLURB" dial to 1, they will all show the morph applied at 1, except Victoria 1 and the Millennium PreSchool Girl. For multiple-figure scenes you need to load a Null before EACH figure, as rbtwhiz's tutorial instructs, and then you don't have to figure out what morphs share names on what figures, even after you save the scene.
