ESP Mod v2.0.2 - Minecraft 26.3

ESP Mod v2.0.2

Changes from v2.0.1

• Skip chunks entirely outside Box Range before checking individual cached blocks. The existing per-block range check still determines which boxes are drawn.
• Reuse the drawing style for each block type in a chunk, instead of creating a style for every box.
• Avoid creating empty chunk caches for untracked block changes, and remove caches when their last match disappears.

The v2.0.1 chunk-boundary update fix and existing presets, colors, settings and dependency requirements are retained. Sections without tracked blocks are still skipped during scans, with one chunk scanned per tick.

Validation

The build and assertion self-check pass, covering chunk-boundary updates, cache cleanup, negative coordinates, exact range boundaries, and a grid comparison confirming the chunk filter does not reject in-range blocks. No FPS improvement has been measured on lower-end hardware, and these rendering changes have not yet been visually checked in Minecraft.

Installation

Requires Minecraft 26.3, Java 25+, Fabric Loader 0.19.5+, and Fabric API for 26.3 (built against 0.161.0+26.3). Mod Menu 21.0.0 is optional.

v2.0.1

ESP Mod v2.0.1 - Block ESP patch

This patch addresses missing ore boxes at chunk boundaries reported in v2.0.0. Minecraft and dependency requirements remain the same.

Changes from v2.0.0

• Placing or removing tracked blocks updates the cache immediately, including in loaded chunks awaiting their first scan. Previously, these updates were discarded until the chunk was scanned.
• Changing tracked types or selecting a preset keeps existing results instead of blanking the cache. Nearby chunks are rescanned first.
• Block changes are captured through the client state's dirty-block hook, including changes that bypass the notification flags used by the previous hook.

The box-range setting still applies to block and entity boxes. Entity ESP uses a separate per-frame entity lookup and was unaffected by this cache issue.

Requires Minecraft 26.3, Java 25+, Fabric Loader 0.19.5+, and Fabric API for 26.3 (built against 0.161.0+26.3). Mod Menu 21.0.0 is optional.

v2.0.0

ESP Mod v2.0.0

This update brings Minecraft 26.3 support, block ESP, custom box colors, and a revised configuration menu. It follows the v1.0.0 release, which was named Spectral ESP and targeted Minecraft 26.1.2.

Saved settings	spectral-esp.json; master enabled state not saved	Separate entity/block configs; enabled states saved

Features and cleanup

• Entity and block box colors can be chosen with RGB sliders or a #RRGGBB hex value, with a live color preview.
• The master toggle controls entity and block ESP together. Entity outlines and hitboxes have separate Show/Hide controls.
• Tracked invisible entities can show glowing outlines. Outline colors continue to follow Minecraft's normal behavior.
• Menus use Minecraft's native keyboard navigation, focus, dragging, and narration handling. Escape returns to the previous menu or cancels color selection/key rebinding.
• Block scanning processes loaded chunks gradually on the client thread. Scanned positions update when blocks change and are removed when chunks unload.
• Entity lookups use registered entity types directly. Unused code, redundant caches, and unnecessary concurrent collections were removed.
• Config saves finish writing before replacing the existing file. Invalid files are logged and backed up, duplicate/invalid entries are filtered, and the saved box range is constrained to its supported values.
• Input handling and entity box submission were updated for Minecraft 26.3.
