Right hand IK goal, pulled the entire body

[Ahmadhp]

Hi,

I am trying to have the punch animation adjust dynamically based on the goal.(similar to the “reaching target” example in the “content example” project)

It is working, but the problem I am running into is that compared to the base animation when IK is active the whole upper body is getting pulled toward the target as well which is not the desired effect.

here is without IK

and with IK

Can notice the glitchy movement of the body (most noticeable at the head)

Any idea why is this happening?

cheers

You can set in IKRig not to use FullBodyIK as the solver. Using a LimbIK will do.

True, I’ve already done that.

Was just curious to know, is there a way to control the FBIK solver so that behavior doesn’t happen, or it’s just part of it?

thanks!

You could Add settings to selected bone (the root bone of FBIK), and set (position/rotation) stiffness to 0.0. You can also try other constraints or prefered settings here.
