best of luck with it pfaber ive also found dae works sometimes too but only saves the keyframes which is a method of improving memory usage
but that comes at a cost where the transition is lost. for example you may have one key frame at 5 and the other at 15 the timing between keyframes
is different so hence that would be lost with dae. There is also the curves between transition which frankly I dont understand that well but in blender
you can change the way it transforms from one keyframe to the next ie on a log upward incline or perhaps a straight line for the transition effect
