Unfortunately the Live Link Face for Unreal Engine App is missing the Calibration feature of the older one you had to compile yourself.
Is this going to be added in?
Turns out the calibration process at the beginning is crucial, unfortunately that’s not included in the current App but you have to manually adjust it in the blueprint.
Would be really cool to make the blueprint do it, shouldn’t be too hard. Just record the values of all blend shapes when your face is not moving and use them as offsets.
