About this Mod

![]()
![]()
![]()
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. ✨

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.

Diagonal Windows server crashes on startup – what to do?

Diagonal Windows officially supports fabric, forge, neoforge for Minecraft 26.3, 26.2, 26.1.2. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Diagonal Windows – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Diagonal Windows consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
