Beacon Blocker
by LazyLyrics
Beacon Blocker changes how tinted glass interacts with beacon beams, letting placed glass cap either the visible beam or the effect range.
What it does
Vanilla Minecraft tinted glass blocks both beacon beam effects entirely. Beacon Blocker alters that behavior: when tinted glass is placed above a beacon, the beam can render through it and effects can continue past it. Both behaviors are optional and set in the mod's configuration, so a server or player can choose one, both or neither.
The mod is a small Fabric addition that works on single-player worlds, multiplayer servers, or either side alone. Its two settings live in the same configuration file. The beam-height option belongs to the client and only changes what the player sees, while the effect-height option belongs to the server and changes which players receive effects. A beacon remains active in both cases, and the individual client values option has no effect in multiplayer.
Beacon Blocker is open source under the MIT License and is published for Fabric only, with one build for 26.2. Work on either side is optional, so a server or a client can run it alone, and neither is forced to install it. Its source code is publicly available.
Key features
Visual beam cap
Tinted glass placed above a beacon lets the beam render through it, so the glass no longer blocks the visible light.
Effect height cap
Tinted glass can limit the effect range, so players above the glass stop receiving effects while the beacon stays active.
Separate beam and effect settings
The beam height and effect height can be adjusted independently, so one can be changed without the other.
Shared configuration file
Both options are read from the same configuration file, which keeps the settings in one place.

What the author says
A small Fabric mod that makes tinted glass interact with beacon beams. In vanilla Minecraft, tinted glass blocks both the beacon beam and its effects entirely. This mod changes that: placing tinted glass above a beacon lets effects continue through it as normal, but visually caps the beam at the glass — the beam does…
