Glassification
by binarygun951
Glassification turns newly loaded chunks of a Fabric world into fragile, color-mapped glass, so a player who installs it into an existing save meets a landscape with no natural shelter.
What it does
Glassification replaces terrain in newly loaded chunks with glass, mapped to colors, while functional blocks and structures stay intact. Existing worlds can be used without a backup, but the replaced areas are permanent, and the mod removes natural shelter and suppresses hostile spawning on that terrain.
The mod supports the Overworld, the Nether and the End. Survival progression depends on mechanical knowledge and planning, since the mod targets experienced players who want a system-driven challenge rather than guided gameplay. The server must run the mod, and a client may join without it.
Glassification is for Fabric only and is published for 1.21.1 – 1.21.11, with 1.0.0 for 1.21.11 as the latest file. It is released under the MIT License and is not open source, and it has no required dependencies.
Key features
Glass terrain conversion
Newly loaded chunks are rebuilt as fragile glass, with block colors mapped from the original terrain.
Core systems preserved
Functional blocks and structures remain intact while the surrounding terrain is converted.
Hostile spawning suppressed
Hostile mobs do not spawn on the converted terrain, which removes the natural shelter of the world.
Overworld, Nether and End
The conversion applies across all three dimensions, so each one changes as chunks are generated.

Natural shelter is removed, hostile spawning is suppressed, and terrain is permanently unforgiving. Survival and progression depend entirely on mechanical knowledge, planning, and deliberate world…
