Csg don't work correctly

Question

Hey. I want to make a play on the similarity of the hole.io. I was told to use css for the floor and holes. But it works in a strange way. I wrote a script to move the hole and rebuild the collision shape. Now objects either fall into the hole or do not fall into the hole. Although there is a feeling that they fall when I touch the hole edge of the platform. What am I doing wrong?

Answer 1

Have you tried to set "Invert Faces" to "On"?

Edit: On your CSGCylinder or CSGBox, or both
