I move the discussion to osg-users. The TimeLineAnimationManager does not really seems appropriate for my needs. Let me explain better. I want to do "cross-fade" between two animations loop. The example shows "continuous blend" not "cross-fade" and between an endless animations and "short" animations. The figures in the following link show what i mean by cross-fade and continuous blend : http://www.gamasutra.com/features/20030704/edsall_02.shtml Maybe it is possible to do cross-fade with TimeLine (using BlendOut for exemple?), but i have preferred to hack a simple method to start...
Then for my blending problems, I see into the code you are just doing addition and substraction on quaternion for blending, is it exact ?

The idle and the scratch. It could help you i guess. The screenshoot is funny :) Cheers, Cedric Fabien Lavignotte wrote: > For blending I have checked osganimationtimeline, the TimeLine thing is quite > nice but i am not sure it cover my needs. > I just wanted to blend smoothly when going from one animation loop to another > (for exemple run->walk, then walk->stand).
