I have a simple (I guess) problem with the orientation of this extrusions.
I made the control curves using the 4 vertices of each subsurface, afterwards I used the normal plane of the "planarity test" plane for each curve, as i want the extrusion to be related to the curve orientation.
Anyone knows how can I make all the planar vectors point in the same direction and chosing wich one shoud it be?
I guess it could be a conditional statement, but can't guess wich one.
