First mesh check? But then it's an bad new algorithm. Because with the old boole it works fine without problems. And why does the new boole not work with single sided polygones? As long the old boole still is in C4D ther's no problem. But you never know ...

I know, you are not the programmer, just here for the forum. ^^

seriously: how does the new boole work? I can't boole an open polygon. Any hint?boole_2026.1.1.c4d
