Smooth transition from Linear to Bezier in animation

[masaki]

hello all,
I was wondering if there is a way to switch from Linear to Bezier translatemode in an animation path without it becoming jerky when the switch happens. I have a pretty simple path that starts off translating in a straight line (this is the part i need to have it linear), and then i need the path to start curving and then at the end it is a straight translation again. I've tried making the straight line control points linear, and the others bezier. I've also tried making a timer function to turn autorotate on and off while keeping all controlpoints bezier. Please let me know if there's a way to make a seamless combination of straight and curved animation paths. thanks in advance.

Have you tried using cubic bezier mode? This will ensure that the object passes through the control point.

Hi farshizzo,
yes i've tried cubic bezier but it behaves very oddly when i use it. instead of following a smooth curve, it swings from left and right between each control point. Oh and by the way, the animation path is linked to the mainview - so any jerkyness is really apparent and i really need a seamless transition. if it would help, here are the control points for one of the paths: positions = [[0,0,0],[0,0,1],[0,0,2],[0,0,3],
[-0.0523359562429438,0,3.99862953475457],
