Im using 3dsmax to set up my nodes for cutscenes properly, using levels builted so its all matching..but on the way i said, i simply need less number of nodes and on way i did it things moving smooth, there is no jagged turnings at all, and I can control speed regardless number of nodes while camera is entirely free to look at any position while nicely moving along path..code is not complex at all and its just one function call..
