v1.3.0 — no server opt-in (MC 26.2, GitHub only)

No-server-opt-in build (Minecraft 26.2) — GitHub only.

This variant removes the server opt-in gate: the see-through feature is always enabled, on any server, with no server-side handshake required. Client-side visual only.

Not published on Modrinth (Modrinth Content Rules §3 require the see-through feature to be server-opt-in). For the compliant, opt-in build use the Modrinth release or the standard v1.3.0 GitHub release.

Same mod id as the standard build — install only one.

v1.3.0 — MC 26.2

Update to Minecraft 26.2 (Fabric loader 0.19.3, Fabric API 0.154.2). Ported 26.2 API changes: screen management moved to the Gui/Hud classes. 26.2 ports: clearColorTexture now takes a Vector4fc; chunk re-mesh moved to levelExtractor.

v1.2.0 - Server-side opt-in

v1.2.0 - Server-side opt-in for the see-through feature

To comply with Modrinth's Content Rules (section 3 - seeing through opaque blocks requires a server-side opt-in), block hiding is now gated in multiplayer:

• Singleplayer / your own world: works exactly as before.
• Multiplayer: disabled by default. A server enables it by installing the mod on the server side and setting allowSeeThrough: true in config/block-unrenderer-server.json. The server then sends an opt-in handshake to clients on join.
• On vanilla servers, or any server that has not opted in, the feature stays disabled and the toggle shows a notice.

Other changes

• ModMenu is now optional (moved to suggests).
• The mod now also loads on dedicated servers (only to send the opt-in handshake). It remains a purely visual client mod and never changes world or block data.

Requires: Minecraft 26.1.2 - Fabric Loader 0.19.2+ - Fabric API

Block UN-renderer v1.1.5

Block UN-renderer v1.1.5

A big update — new categories to hide, real Sodium/Xaero fixes, and a major performance pass.

New

• Hide liquids — one-click Liquids toggle (all water/lava) or add specific fluids to the list. Works under Sodium and covers flowing + waterlogged.
• Hide entities — Entities toggle hides all mobs / items / projectiles.
• Filter modes — Hide listed (blacklist) or Show only listed (whitelist).

Fixed

• Xaero maps no longer distorted — the guard now wraps Xaero's real samplers (MinimapWriter / MapWriter), so hidden blocks stay on the minimap and world map.
• Sodium fluids — water/lava now actually hide under Sodium (its fluid renderer was bypassing the vanilla hook).

Performance

• All per-block render hooks converted to zero-allocation MixinExtras @ModifyReturnValue, the map-guard cached per-thread, and config flags mirrored to volatile fields — eliminates the world-load GC churn that hit low-end PCs. When off, it's a single boolean check.

Changed

• Removed Night Vision (FULLBRIGHT / OFF only, FULLBRIGHT default).
• Dropped the Cloth Config dependency; restored the custom searchable icon picker with a cleaner two-group button layout.

Requirements: Minecraft 26.1.2 · Fabric Loader 0.19.2+ · Fabric API · ModMenu

Block UN-renderer v1.1.0

Block UN-renderer v1.1.0

New

• Filter modes — Hide listed (blacklist) to make some blocks invisible, or Show only listed (whitelist) to make only the listed blocks visible. One list, switch the mode.
• Map-mod friendly — no longer distorts Xaero's Minimap / World Map. Block states are never changed; the map keeps showing the real world while blocks are hidden from your view.
• Config via Cloth Config + ModMenu, plus the searchable icon block picker.
• Keybinds unbound by default, under their own Block UN-renderer controls section.

Requirements: Minecraft 26.1.2 · Fabric Loader 0.19.2+ · Fabric API · Cloth Config · ModMenu
