WebDisplays 2.6.0 for Minecraft 1.21.1

Bugfix release with two new features. All fixes are responses to CurseForge user reports.

Bug fixes

• Screens no longer blank out at certain camera angles. Long-standing rendering bug, fixed by switching to a custom render path that bypasses Minecraft's per-section block-entity culling.
• Spatial audio now actually attenuates with distance. Audio is also no longer audible from miles away.
• Client config is now respected. load_distance, unload_distance, audio distances and other settings actually take effect.
• Display blocks drop when broken (no longer require a pickaxe).
• F1 wiki hotkey opens the wiki.
• Multiplayer sync improved. Late joiners see the same content as everyone else.
• YouTube playback works under the new MCEF.
• No more duplicate audio when crossing the load/unload boundary.
• Screens turn back on when you walk back into range (previously stayed off until block reload).
• Turn Off → Set new URL works (previously left the screen stuck until you broke the block).

New features

• Turn Off button in the screen configurator — loads about:blank and broadcasts to all viewers.
• Per-screen volume slider (0–100) next to the Off button — type a number, press Enter.
• Thin display block (webdisplays:screen_thin) — a 1/16-deep variant. Craft 1 regular screen → 4 thin. Mount on a wall, ceiling, or floor; inner edges of multiblocks hide cleanly.

Upgrade notes

Required: Replace your old MCEF jar with Keksuccino's MCEF 2.2.0-1.21.1:

• https://keksuccino.github.io/maven/de/keksuccino/mcef-neoforge/2.2.0-1.21.1/mcef-neoforge-2.2.0-1.21.1.jar

(Same Chromium 116 as before, additional render-thread + NeoForge fixes.)

If you have an existing config/webdisplays_client.toml, you may want to delete it to regenerate with the new defaults, or update load_distance, unload_distance, and audio_silent_distance to the new values.

Known limitations

• Mixing thin and thick screen blocks in one multiblock works structurally but renders inconsistently — stick to one variant per screen.
• Thin blocks: place all blocks of a multiblock with the same FACING and use the linker on that face.

Audio diagnostics

If audio attenuation seems off, launch the dev client with -Dwebdisplays.audiodiag=true to log per-screen audio state every second.
