Upgraded Glass

The mod adds several special glass blocks. Some emit light, some let light pass through while still blocking mobs from being walked through, and some are described by the author as almost indestructible. A few types are meant to stay hidden until the player looks for them, and pressing SHIFT in the game reveals their features. Some glass blocks also break in a particular way when mined, emitting light only to players who pass through them.

The mod suits decoration builds, where the light-emitting and transparent variants can be placed in walls and ceilings, and it can be included in a modpack to extend the glass options. Both the server and every player need it, because the glass blocks are placed and interacted with on both sides. Files are published for Forge and NeoForge, and the code is not open source; the mod is released under All rights reserved.
