Block UN-renderer
by Limucc
Block UN-renderer lets a Fabric client hide chosen blocks and their block entities, so the player can see what lies underneath them.
What it does
Players pick the blocks to hide from an in-game picker, opened with the O key. The picker has a search field, and each block is shown with its icon and can be added or removed with a click. Hidden blocks cover chests, furnaces, stone, leaves and any other block ID. Hiding can be switched with the X key, either as a toggle or as a hold, and a Hold or Toggle trigger mode is available.
Show Blocks Underneath keeps the surface beneath a hidden block rendered, so holes left in the terrain stay readable. A fullbright option lights exposed or covered blocks through a per-block luminance technique, which works with vanilla rendering and with Sodium. The instant mode changes hiding without a delay and without a performance cost, and the mod is a lightweight client addition for Minecraft 26.1.2 and later builds in that line.
Block UN-renderer requires nothing beyond Fabric itself. It is a client-side mode of play: only the client needs it, and a server can run without it. Files exist for 26.1.2 and 26.2, the latest being 1.3.0 for 26.2, and the code is open source under the MIT License.
Key features
Searchable block picker
A GUI opened with O lists blocks by name and icon, so chosen blocks can be added or removed with a click.
Hide any block
Chests, furnaces, stone, leaves and other blocks can be hidden, including block entities that normally render on their own.
Show blocks underneath
The surface under a hidden block stays rendered, so holes in the terrain do not appear as empty space.
Fullbright for covered blocks
Exposed or covered blocks can be lit with a per-block luminance technique, so they remain visible while hidden blocks are gone.
Toggle and hold keys
The X key switches hiding on or off, or holds it, with Hold and Toggle trigger modes available.

How it compares
Vanilla Fullbright is a client-side only mod for 26.2, open source under the MIT License, and it only lights the world. Block UN-renderer is a client mod too, but it hides chosen blocks and their block entities instead. DevJG's Fullbright is client-side only, open source under the Mozilla Public License 2.0, and covers 1.21.9 – 26.3, while Baston's Tweaks is client-side only and not open source, with files for 26.1.2.
