Diagonal Windows lets glass panes and iron bars connect diagonally, opening up new ways to shape windows and detailed builds. 🪟 Small change, but it makes structures feel noticeably smoother and more natural.

It also supports blocks from other mods whenever possible, with full control over exclusions through the diagonalwindows:non_diagonal_windows block tag. ⚙️ Works cleanly with most resource packs without extra setup.

Part of the Diagonal Blocks family, alongside Diagonal Fences and Diagonal Walls, expanding diagonal building in different directions. ✨

⏩ INSTALLATION REQUIRED ON CLIENT & REQUIRED ON SERVER

⏩ REQUIRES PUZZLES LIB TO BE INSTALLED (FABRIC & NEOFORGE)

⏩ REQUIRES FABRIC API TO BE INSTALLED (FABRIC)

⏩ REQUIRES FORGE CONFIG API PORT TO BE INSTALLED (FABRIC)

If available for a mod, configuration is possible directly from in-game using the mod menu (requires Mod Menu by Prospector to be installed on Fabric).

For manual configuration using an external text editor all files are found at .minecraft/config, named as MOD_ID-client.toml, MOD_ID-common.toml, or MOD_ID-server.toml, depending on the type of config. Not all types might exist for a mod, if any at all.

🌟 Thanks a lot to XFactHD for contributing the diagonal model transformation code and helping out during development in general!

🌟 Thanks to Magneticflux and their Diagonal Panes mod for serving as an inspiration.
