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.

Bits 10 and 11 are now implemented as of SMMU v3.21.

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.

These new bits are added since the MBF21 editing standard.
 
===Instant death sector===
A new bit is added in MBF21, bit 12 under classic format and bit 15 under UDMF. When this bit is set, bits 5-6 (classic) or 8-9 (UDMF) change their meaning from "sector damage" to different variations of this instant death sector type, as shown in the following table:
