Tob's Blender 2.5 Foot Rigging Tutorial 2/10 Armature and IK

Continuation of a foot rigging tutorial using Blender 2.5 (pre beta release).

This section takes you from an empty scene to having all the inverse kinematics (IK) for the rig setup.

I was and making sence of things until around 5:00. You started parenting bones left and right and im like wtf? How do you understand all that soo well? Its complicated logic but i for one am going to practice til i know it as well as you do!

Thanks for the tutorial(s)!

@Johneysteel : ) the big secret is that I don't understand it all that well myself. When I need to make a new rig, the first thing I do is re-watch this video!

When I made these videos I spent a couple of days building up the process based on a tutorial I'd read a few years earlier, so I understood it fairly well at that point. I only occasionally do rigging so I get out of practice.

Anyway you have the right approach, ie stick with it and it'll sink in just as much as you need it to.

Followed in 2.49, all working well so far, making me feel like a rigging god already, thanks!

You've not used ctrl+i in this to set the IK target, I found this really useful, is there a reason not to use it?

[tobuslieven]

@jeffreyser ctrl+i sounds fine. I didn't know about it, but for instruction purposes its nicer to see the process of adding a constraint in the bone constraints panel anyway I think. Pressing ctrl+i would have made it seem like I was using some magic invocation rather than doing something easy and explainable (but yeah using shortcuts in blender is great).

For anyone struggling with the parenting here's a run down in text form.

Dupe SHIN for LEG TARGET.

Dupe TARSAL for TARSAL.

Dupe TOE for TOE TARGEY, TIPTOE, ROTATE TOE, HEEL and FOOT, in that order.

Parent LEG TARGET to TARSAL TARGET, TOE TARGET to ROTATE TOE, TARSAL TARGET and ROTATE TOE

to HEEL, HEEL to TIPTOE and finally TIPTOE to FOOT, now clear the parent of FOOT.

Fantastic tut, thanks much for this ^.^

Very good rig. I followed all ten parts and took a long time doing it. When I was finished I had some problems because I missed something in the first few seconds of the first video. You go into right view (numpad 3) and I didn't. You rotated the first bone in edit mode by grabbing one end. I rotated in object mode and from that moment on my bone axis were messed up. Other than that I had no problems. How do you make the double headed arrow for the action constraint?

I created an image with my notes in Spanish, if someone could be interested

Thanks!

Outstanding.

[iambubbathedog]

How do the controls connect to the other bones when you duplicate/move them?

[YTDekus]

This is great.. watched it like 3 times. Very useful.

Thank you for sharing.

Awesome tut, I am trying to rig a skeleton and I hope this will help me finish. Thanks!

One question though, why do you have to make the target as a copy of the original? I tried without doing that and it didn't work but i don't get it.
