Thanks for that amazing video! it was very well received in the S800/600 FB group I'm inEnjoy, and dont forget to check out highlights!
Nice! didn't know that would work without messing up the entire rig. I'll give it a try once I get down to it, thanks!View attachment 384099
to scale the complete driver you use scale on the DRIVER_RIG_Center element in Pose mode, iirc this was something that somehow only worked with Blender and the Blender rig from Stereo, haven't tried this yet in 2.8. In the pic above I used extreme values to make an invisible driver for a commissioned project.
but you can use it on single bones too, I think i shrunk the head on some driver once to make it fit better
