When it comes to creating a custom character rig using CAT, an understanding of CAT's use…of hubs is essential as the hub is a building point for many aspects of a CATRig.…A Hub is a special type of CATBone.…Typically, it's a foundation from which spines, arms, legs, and tails are built.…A few specific examples of a CATHub would be a pelvis or a ribcage, maybe even a head,…depending of course on its function within the rig.…
To actually create a CATHub, we first need to create a blank CATParent, which hopefully…by now we are quite familiar with.…Let's come over to our Helper section and dropdown our list and choose CAT Objects.…Let's select the CATParent button and then click and drag in our viewport to create the Helper.…I just want to make some modifications.…I'm going to change the CATUnits Ratio to 0.338, just to make it a little bigger in the scene.…
Next, I want to orient it so it is facing the same way as our creature.…I'm going to right-click and come to the Rotate tool and then press the A key to turn on our angle snap.…
