I have the given setup in my AnimationTree node :
This is the character I am animating :
The state machine handles walking/idling animation, which has some animation on the ponytail. The 1D blend space handles the head looking up/forward/down, applying some rotations on the ponytail nodes (this animation is the blend space going from -1 to 1 and vise versa) :
The issue I have is when i set the Add2 node in the animation tree to 1, then the ponytail animation from the state machine is totally overridden by the animation from the blend space, and if I set the value to 0.5, then the head motion jitters around 0 :
Is it the expected behaviour from the Add2 node ?
How I am supposed to correctly add the two animations ?
Thanks for the help.
