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

        Hi notice-world,

        Thanks for the file.

        Please select your city model and use the Attribute> Mode> Modeling> Mesh Checking.

        You might notice that the model has severe problems: 68 bad polygons. The algorithm can't operate on that.

        More about this in detail:

        The problems need to be fixed first. It looks like a CAD model, and my tip would be to check if the export from that software can be improved.
        There is no simple "repair", I tried a few first aid options, but none can deal with this.

        All the best

          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. ^^

            Hi moebious0815,

            Thanks for the reply. So, in short, even with 68 bad polygons, you want the algorithm sort it out for you and provide a perfectly solved Boolean operation.

            Even some models are based on flat polygons, for example, not even producing a volume" (when you “explode” the collection, you see how unusable it is constructed).

            I get your expectation, all of that care to create clean models is not needed; it should work no matter what anyway. Sorry, there's nothing I can help you with.

            In short, you state that it is not working, which means you need to contact the Tech Support.
