Hello guys! I’m making a rig of zeratul from star craft and he have some weird lesg like aliens and stuff, it’s composed of 3 bones and I have no idea how to Ik this thing or how to move it in a optimal way.
I have set a ik in the foot but it a bit horrible to move the knee
where do we have to start?!
arrange the bones in the side window down to ground
then create two more bones that are free in the Hirachy
one will deviate the foot position the other will point to the knee the pole-vector
after the chain has an Ik constraint you have to enter the chain length, in this case there are three,
see picture
or blenderfile
three_legged_ik.blend (625.3 KB)
arrange this and the constraints are assigned in edit or posemode, so it is not surprising in Blender if some menus are missing,
highly recommended
