View Full Version : Help With A Quadruped Rig

 HaleyO02-13-2009, 06:06 PMHi there! I am currently working on a canine-like creature and have gotten to the rigging stage. Now, I am really stumped on this. The skeleton is built and I've gone ahead and made controls where I think I might be needing them, but am unsure of how to hook it all up to make it look right. I have rigged humans before, and tried a similar approach, but I found it very awkward for a dog-like animal. I have also tried looking up tutorials and have been having a tough time with that. If anyone has some suggestions or knows of a good, well detailed tutorial, please pass it along! It's really just the legs I'm having difficulty with. Thanks in advance!

Well, without more specifics into what your problem is, I'm going to guess that you're making the common mistake of creating the IK handle down 4 bones instead of 3. Rigging a Quadruped leg is similar to rigging a humanoid leg, only you treat the Hind leg joint as the ankle instead of the joint closer to the end of the paw. Then you treat the base of the paw like you would the ball of a human's foot, and the toes as toes.

So understanding that logic, really any tutorial should be able to help you.

Hope this helps.

Couldn't you have the IK run down the whole chain and simply move the effector to the joint that is located above it?

Since you haven't skinned or anything, you can try just using setup machine or advanced skeleton. It sets it up for you and all you need to do is adjust where the joints are and fix the weights a bit. And they have set ups for both bi-peds and quadra-peds.

Or just download rigged dog from highend 3d and see how they rigged it. Best of luck!

Your method allows for a faster setup with some automation for the hind leg, which can be a good thing. You're leaving the orientation of the hind leg to the mercy of the IK handle and you may not always like the results in the long run.

Rigging it like a human gives you more control over the behavior of the hind leg, which is a good thing, but it takes a little longer to set up and you'll have to create attributes or extra controls to make full use of the rig.

I guess it comes down to personal preference really. Even if I end up replication what the IK handle already automated, I feel a little safer knowing I have that control if the situation arises.
