Guys, question — Can you use ik to deform and control a b-spline patch obj? for example, let's say I build a face with b-spline patches, can I control portions of that face (lips, eyebrows, etc.) with ik bones? or does ik only aid you in moving objects? another question — it's my understanding that you can build a b-spline obj and convert it to polygons, but can you go from polys to b-spline? – and if you can, to what extent (mesh detail, etc.)? one more — I know that there is an .axp used with b-spline obj ( that deals with the amount of detail rendered) — thus depleting your ability to use any other .axp (vapor or flame) — any chance we'll be able to use multiple .*xp's in the future? thanks, -kyle
