i was going to say the same thing but i think he wants the whole spheres deleted (and only those which intersect)…
somehow, if you could link the group of the inside part of the sphere (the part that's intersecting) from the cookie with its connected edges of the spheres before the cookie… i dunno.. still thinking..
my idea would be the following: switch between the sphere ( let's say it's A )and a nullSOP depending on if A and B intersect ->that is if ( A intersection B) is not Nothing, ->that is, for example if npoints(A intersection B) != 0
