i have this logic: A is opposite of B and they can be compenetraed, infact the resul is D where the grid is full on. Now i want put an other term C with A and B and from the compenetration of A,B,C the result is still D .
The only hit on Google for “compenetraed” was this post, congratulations on making up a brand new word :)
What you are doing could be done with an OR node, and you can use a NOT to invert boolean, I have no idea what you want to do with C, sorry that I can’t help you here.
And just attached a patch, screen-shots are annoying, cozz now I have to rebuild your patch. Most of us here have vvvv installed I think.
