Purpose: use the cookie node to get just the part of the concave polygon that lies inside the box
Problem: the result is weird because some parts of the concave sharp outside the box is not subtracted and some strange triangular connecting point 6, 15, 16 is also created from nowhere inside the box…
the convex polygon seems alright in these nodes…
should i do something to the concave polygon before connecting it to the boolean cookie node?
