KantoBlocks
by CobbleKanto
KantoBlocks is a Fabric decoration mod that adds more than 480 building blocks for Kanto-style towns, routes, caves and interiors.
What it does
The block set covers city floors and walls, route sections, cave tiles, gym and tower interiors, mansions, ships and endgame-themed pieces, grouped for builders who make adventure maps and survival worlds. Some entries are plain cubes, and the rest take custom forms like slabs, stairs, doors, fences, panes, carpets, signs and plants, which means directional placement behaves the way a builder expects.
Several blocks use connected textures through Athena, which blends walls, floors and cave tiles so large interiors do not show one repeating square texture. Athena is required for that visual result. The KantoBlocks Converter utility block provides a scrollable block palette: a player inserts a valid currency item, selects a KantoBlock and receives it. Converter support covers copper ingots and compatible ball-tag currencies. The mod runs on client and server, so the server and every player need it, and it is published for 1.21.1 only under a custom license that is not open source.

How it compares
Better Glass Panes is a Fabric client and server mod for 1.21.1 under the MIT License and is open source, so it adds only panes. KantoBlocks is a separate Fabric decoration kit for the same version, but its custom license means it is not open source. COBBLEVERSE: Badges & Trophies also runs on client and server for 1.21.1, under a Creative Commons Attribution Non Commercial No Derivatives 4.0 license, and is not open source.
