Originally posted by Tolerate XSI doesn't have the hiearchical (sp?) mode to there subd's unlike Maya, but there are soooo much faster and easier to use The reason theyre so much faster is exactly because of that fact - theyre not heirachical. if you just use mayas sub's at level 0/1 then the speeds between the two apps are comparable . the other thing that slows maya subd's down alot is that theres an awful lot of excess baggage nodes that seem to sit there an slow things down. make a habit of getting rid of the blind poly data nodes and history every so often and things stay pretty interactive
