Hey everyone, I am rigging a character getting ready for animation. I am having a problem with the IK handles. I added a nurbs curve around the ankles with an ikRPsolver from the hip to the ankle and an ikSCsolver from the ankle to the toes. I parented the ik handles to the nurbs circle. and it moves wonderfully. I am trying to make it so when I click on the rootjoint between the 2 hips and translate it down, I want it to bend the knees but it just translates the whole thing down. I’m not sure what I am missing.
any help would be much obliged.
thanks.



Tristan

Hi Skorpius,

I’m not specialized with rigging, but you can try doing a test with only joints. Having just 1 IKhandle from hip to ankle and parent-constrain (instead of only parenting) the IKhandle to a curve control. Remember to select the curve then the IKhandle when applying parent-constrain.

I moved the root joint down & the knee joint bend as desired, worked for me.
Hope this helps, good luck! :)

or you could do it like this:
select your IKrp solver hanlde, go to its attribute editor and under IK handle attributes choose
> Stickiness -> Stick
now it will stay in place. 

An other solution would be to constrain each IK handle at the leg to a control object. (i think you did so? )

I attached an image for a Leg Rig use the IKsc for foot ball and toe, and constrain an object to each of one. Now when you grab the root joint and drag it dow, the foot will stay planted like your char was standing on the ground - just nice^^

hope this was helpful for you :)
