Fixing the face

Finally took 5 minutes to identify a bug on the face controls that's been bugging me ever since I started blocking. The left eyebrow expressive control was behaving differently, all because one of the interpolation curves in one of the node utilities was incorrectly remapping the values.

That doesn't make any sense to me either. Good thing I documented this rig...

In case it comes up again: the node in question was L_BrowExp_Xremapper.
