IK/FK snap

[omkar-jere]

I guess you can manually alter the PV do the following steps to see if it works:

1. Create a locator
2. Snap it to the knee joint(don't constraint) and then Orient constraint(with no maintain offset) it to the knee joint
3. Delete that orient constraint(use outliner if finding it difficult)
4. Now apply poleVector to the ikHandle using the newly oreinted locator(make sure you don't freeze transforms for the locator)

You can then delete the locator if you wish but that will also delete the poleVector Constraint but should keep the knee in the correct position.

It has worked for me many times. Try it. Good Luck.

This defintely worked but then I get rotation values in my first leg joint instead of it staying at zero.

I have a 4 joint leg btw

Try deleteting the Ik Handle now then Freeze Transforms(only rotation) for the 1st joint then re-apply the Ik handle.

Thank you for all your help, I have everything working and am able to continue forward! I only have one more question, I tried to create an IK-FK switch/snap for the legs of my character just like the arms, and it works for the most part as far as the scaling goes, but it doesnt match up perfectly because the rotate values are different, do you know of any way to set this up or should I not even bother?

Does the dvd have Ik-Fk snap video for the leg ? it maybe a little bit different than the arm.

You shouldn't bother much about it much. I remember how that DVD was a nightmare for me now I don't mean he is a bad artist just that he doesn't teach very well. It is quite confusing for beginners.

About the rotation sometimes constraining an object may have offset so use blendColor method rather than constraints if you don't know how to set it up then here you go:

I agree, I skimmed through the animation friendly rigging tutorials and he literally covers EVERYTHING I need, the ik/fk matching with scale on the arms and legs, with matching elbows and knees, but I do prefer the ribbon spine and the auto clavicle from the fahrenheit tutorials, so I think I'm going to rebuild the arms and legs using the anim friendly tuts and keep the midsection of the other rig, hopefully I wont have problems piecing it all together when I'm done.
