More technical stuff! So if you don't do 3D, just scroll down to the pretty stuff!
Here's a script I made to automatically rig a spine. What it does is tackles some problems seen in conventional spines. Jason Schliefer's spine is awesome, but I wanted to make it so three problems didn't happen.
1.) Every Control can be rotated in any direction and twist the middle, bottom, and top.
2.) Being able to twist endlessly without any flips ever.
3.) Fixing the typical problem when making an IK spline spine, when using the arclength to drive the scaling of the bones. If you think about it, a curved surface is always longer than linear joints. So the more scaled the curve gets, the more inaccurate the scaling. That's why you get weird scaling. Instead, I used locators along the curve and measured between them linearly. This gives us the true length of the joint chain.
I added ontop of this stretch and volume retention, all with switches on and off.
Hope you like!
