Ik rig severely deforms, target pole rotates torso? For some reason my rig's targer pole isn't working properly. I was trying to practice rigging poses by using an image as reference, but I didn't know why my pose was limited and it wasn't deforming cleanly or realistically. I tried to clear the pose using alt s and alt r and alt g but for some reason it isn't working.



I tried using forward kinematics but my rig seemed to deform like paper, but I'm not sure what to do to make it move realistically
I think what had happened was that there were as I suspected, weighting issues, hierarchial problems and bones had been edited in the wrong mode which can cause problems with the set rotation, scale and location in pose mode.

Here I've given you an example of a rigify rig which comes with names and and logical hierarchy. It will need weight painting to fix deformations of limbs but it'll give you a head start.

Good luck with it
