Rig for Quadruped+Biped together


what's the best "T-Pose" for a quadruped animal that is also able to move like a human being (on two legs)? I'm currently modeling a Hamster and he should be able to move like Reepicheep from "The Chronicles of Narnia" but I'm not sure how to setup his standard pose to fulfill both needs: quadruped and biped.

Here's a little Breakdown from Narnia, that shows. what my Hamster should be able to do:

Thanks in advance and best regards,

I'm curious if you found a solution to your question. I, too, am working on a biped-quadruped switch rig, but mine is for a meerkat.

I watched Narnia last night and paid special attention to Reepicreep (honestly, he was the only reason I watched the movie). I also had a look at the making of breakdown that linked to.

In the breakdown it is obvious the TDs created a skeleton, muscle system, and rig that all conform to a normal mouse's physiology. That is, unlike a biped where the shoulders spread apart from the chest, on a quadruped the shoulders sit directly next to the rib cage. This naturally places the arms down much more.

When Reepicreep goes into biped mode, they animators seemed to tackle this shoulder issue by giving him a lot of flexibility around the forearm and wrist, all the while keeping the upper arm held close to the side of the body. There are a few quick frames where he opens his arms up wider, but I never saw any animation where he actually opens them as wide as a human in a T-pose. Probably at most it would have been an exaggerated M-pose.

In answer to your question, I think if you want a single rig to permit you biped and quadruped flexibility, you have to sacrifice some of the movement in the shoulders and forearm. If you want to create maximum flexibility, then you will likely need two separate rigs.

If you've found a solution to this issue, I would be very happy to hear what it is. Does it fall in line with what I said? Or perhaps you have developed a different/better solution entirely.

Depends on what pose he will be in most the time I guess.

if he's gonna be standing on his 2 back legs most of the time, model it in a stand up position, if i remember right, reepicheep was done like that..
