Blending IK with animation over time

Animation
1

Hi,
I recently got my hands dirty with some IK and decided to try some of The examples Autodesk seems to show off e.g. Kicking a ball in FIFA.

The apporoach

My plan was simply to solve the IK at the frame the player balances before the kick (Animation triggered) then slowly blend it with the kicking animation ease in and out.
The IK was solved with the player at the tpose to avoid crazy issue that arise when you solve from an unknown pose.
This bone data was saved to an animation clip and added to the player’s animation object.

The problem

No matter how hard i try i cant get it to play with the main animation. I did try playing the ik created clip on its own and it worked but when i try blending it doesnt workadditive or regular it did not work. Mixing transform is out of the qestion cos its a singl frame.

For additive i used two keys key 0 had a value of 0 and time of zero. Counfused about the time i should give key 1 since the timing should be irrelevant so i gave it 1.

Well I have settled for mannualy slerping the rotations. I still think using animations might be faster but who knows.

Its certainly could be smoother.

You may have a look at how it is done in the Locomotion System. It does exactly the same, but uses it to align the feets to the ground.
There is certainly a lot of code in the Locomotion System, but maybe you find something useful.

Locomotion system does not blend the results it simply overides

Sorry, didn’t remember correctly in that case.

No problem i am learning a new ik system that doesnt need blending and can be animated/solved every frame for less 1/10 of cost of a single ccd solve.

That sounds interesting! I hope you find your answers!
