I've been reading about everyone working with a Squench rig? I'm just getting used to the 2001. Is this a whole new learning process?

The Squetch Rig is a rig that has squash and stretch built into every joint along with built-in controls for the face, limb bowing, IK/FK switching for seamless transition from IK to FK (or the other way around), an optional single-bone hand control (Steves Hand Gizmo) and a lot of other built-in stuff that would make for an extremely long list.

The Squetch Rig is what is being used in TWO (TinWoodman of Oz) and has continued to be worked on throughout it's production (there's going to be another extensive update soon).

The installation method differs from the 2001 rig and is more difficult...it will get easier, but for now it is still moderately difficult. If you are new to rigging, I would recommend the 2001 rig to start. Once you get a good handle on rigging, the Squetch Rig will make more sense you you.

In my signature, there is a link to the Wiki. There you can find links to example videos, installation versions of the rig and Squetchy Sam. If you want to do some messing with a character rigged with the Squetch Rig, Squetchy Sam is kept up to date with each release.

Hope that helps.

That helps a lot. I'm still getting the 2001 rig down. As always so much to learn. One thing I don't understand...for older models that don't work with the 2001 rig. Am I better off putting in the 2001 rig, or just making actions off the old rig?

Any model can be rigged with any rig, but, if the character is already rigged it will take less time to just work with the installed rig rather than install a different one...unless the installed rig can't handle what you need it to do, then you would just end up fighting with the installed rig.

Hope that helps.

Yes it does, thanks. I was checking out the links, very interesting stuff.
