Eternity provides generalized sector types, based on bit fields, that allow several sector type properties to be independently specified for a sector. Texture change linedefs can be used to switch some or all of these properties dynamically, outside lighting. | Eternity also provides generalized sector types, based on bit fields, that allow several sector type properties to be independently specified for a sector.

Bit 10 suppresses all sounds within the sector, while Bit 11 disables any sounds due to floor or ceiling motion by the sector. Bit 11 is especially useful in silencing constructs such as pseudo-3D bridges, which give off an undesirable plat sound when they move. | Bit 10 suppresses all sounds within the sector, while Bit 11 disables any sounds due to floor or ceiling motion by the sector.
