Bug error when "Adapt Mask" into small size head face

[enzyme69]

Hi Alesssandro, after painting weight and defining read area, pressing Adapt Mask gives me nothing, just an error that keeps me going back to paint but not producing mask.

Apparently after some tweaking, I realized my face scan size is wrong.

Thanks @enzyme69 you are right. We should add that information.
