We’re finally in the driver seat! Yesterday, Ton and I went over a list of to do items for the animation features needed for project orange. Today, he committed IPO drivers in blender (the top of the list).
Currently this is limited to using object transformation or bone poses to drive any IPO curve you want.
Here’s a rather boring little video showing this feature in action: face-slider test. As you can see it’s incredibly useful to have a 2D slider controling 4 different facial shapes at once.
Further, you can replace the custom controller with a bone; use bone rotations to drive shapes for automatic muscle bulges, flesh compression or even cloth wrinkles. Andy made a nice little test anim to show cloth wrinkling and twisting as the character moves his arm.
 ok, as promised, here’s the .blend file for the scene… again, you need the most current cvs to run this - and there are a couple of wrinkles with actions and drivers yet- they’ll probably be fixed very soon, but they might mean you have to choose between normal armture animation and drivers for now: driver controller test file
 Ton fixed the updating problem for bone drivers.. the jaw/look and eyelid controllers should work fine now, including live updating in the viewport.
