Upgraded to C4 pro a few weeks back and have been deep into it and have found that it's an worthy improvement over C3. Anyway, I got C4 basically for the Morph targets (and the, to me, non-functioning arrow-key nudging) and have finally finished a human model to add some morphs to. I've been adapting the concepts in Jason Osipa's "Stop Staring" book to C4 and I created a morph area that includes the vertexes of the lips, lower gums and teeth, upper lip and cheeks. I then created a morph target and rotated the chin and lower lips/teeth/gums. (BTW, buried in the User Manual, which is itself hidden within the "Help" section of the C4 install, is a great tip for controlling where the rotation of selected polys will be -- command/ctrl and option/alt click on a vertex point with the rotate tool selected will establish the orgin of the rotate). Anyway, it took a hour or so to tweak until I liked the shape. I then created a morph area, that included the lips, chin, upper lip and cheek. Basically the same area as before, but w/o the lower teeth and gums; since this was going to be the Smile morph I dont need to move the teeth. I spent another few hours tweaking the smile and then validated the morph and closed the modeling window. Back in the assembly room, I tried out the morph, hoping to combine the open mouth morph and the smile morph -- when I discovered that all the changes I did to the lips for the open mouth morph were lost. It seems to me that whenever two morph areas share the same polys, the one that got created last, will "stay" while the older one skips town... Has anyone else experienced this? The behavior does make sense, sure wished the manual had mentioned some of the morph area/target limitations, though. TIA, mike r.
