Glassential (Fabric/Quilt)

Glassential adds glass blocks with specific behavior. Luminous Glass emits light the way Glowstone does, and Redstone Glass sends out a strong redstone signal like a Block of Redstone. Ghostly Glass lets non-solid entities pass through, while Ethereal Glass lets sneaking players and entities pass through it. Reverse Ethereal Glass works the other way, letting only solid sneaking players and entities stand on it, and fluids are affected by it as well. Tinted Ethereal Glass and Tinted Reverse Ethereal Glass combine the tinted glass properties with those of their Ethereal counterparts.

The mod is aimed at building projects and at players who want extra glass options without installing a large content mod. Like ordinary glass, the new blocks let light through while emitting or blocking it as their type dictates. Several other mods, Extra Utilities among them, also add a range of glass types, and the author notes that more glass variants are planned for later releases.

Installation requires Fabric API. Glassential is a client and server mod, so the server and every player need it, and it is released under the MIT License as open source. Files cover 1.17 – 1.21, with 6.0.0 as the latest build for 1.21 on both Fabric and Quilt, and snapshot builds are published.
