ropehang = <bool>; // Sector is a rope hang. Must be applied to a 3D floor.
jumpflip = <bool>; // Sector flips the gravity of players who jump from it.
gravityoverride = <bool>; // Reverse gravity effect is only applied when an object is in the sector.
nophysics_floor = <bool>; // Disables floor slope physics if created through a plane equation.
nophysics_ceiling = <bool>; // Disables ceiling slope physics if created through a plane equation.
