I’m having another go at rigging in blender but I’m having some issues with shape key drivers, doing correctives -
Let’s say I have 3 shape keys, a jawOpen, a smile, and a corrective shape key. I’m setting up drivers for the corrective with defining the 2 other shape keys as variables.
What I would want is the corrective shape key to activate only if both shape keys are used, so averaged value didn’t work for me since that’d dial on the corrective to an extent even if I use only one of them.
Does anyone have experience with things like this? I’m sure there’s a way with scripted expressions but before I start endless hours of googling I figured I’d ask.
