Perhaps someone knows why this is:
Although I am positive that I connected all goals to the selected solver and that I selected the root bones of those goals to the selected solver, I’m still getting this error when I try to create an IK retargeter:
“IK Retargeter has target bone chain, RightLeg that references an IK Goal, RightFootIK that is not present in any of the solvers in the IK Rig asset.”
Was able to solve this.
Apparently it is super important to rename your Goals with “IK” in them.
If it’s a newly added foot Goal, it should be name for instance LeftFootIK for it to be selectable in the chain and also there must be a chain which uses that Goal, it can’t have a Goal without it being selected in one of the chains.
Hopefully this saves someone some time.
