Fixed.

I'm sorry, when I said the word "manually", I was referring to the English definition that meant you have to remember to do something, and then do it.

That's just my opinion, I didnt like the approach, so I'm looking for another way. Since ICE is modular by design, there should be an acceptable alternative to what was presented in the Rabbit Rig video.

The point of the video was to answer the question, "What does the 2 Bone IK node do?". I personally didnt know, so I researched it. I think the video successfully answered that question. You can apply the results however you are comfortable with doing, and I think that is the point of community generated content, you can take from it what you want and leave the rest without paying for it first and finding out you already knew 90% of the solution, but had to pay $49.99 for the other 10%.

What page where you reffering to? The "egg" ik ice example? Your linking isn't going anywhere except the autodesk site.

I'd recommend to understand the rabbit rig as much as possible, to understand his approach thoroughly. You are right, there are many ways to do something and your example for IK is fine, but if you need to rig a spider or centipode, your run against a wall with your method. Also the direct assigning of kines might lead into evaluation problems later on with the different stacks.

If you manage to come up with a different approach for multiple legged animals I'd be more than glad to see an alternative way for rigging.

Keep it up.

It's the 2012 Online Docs: Contents - ICE Kinematics - ICE Rigs.

It just talks about the overall principles of ICE Rigging and how there is no "best practice" approach, only principles. They mention the Rabbit Rig as one example of those principles in action.
