I just can't figure it out why it does not delete half of a mesh. Trying to do so in geometry nodes.
I want to delete the bottom half of it along the Z-axis but I can't, it acts like it has only 6 faces, these subdivided faces aren't helping at all.
Normals of new faces do not seem correct, I don't know why. It's like there is only 3 states for faces: -1, 1, nearly 0.
If I do it with UV sphere it works
