Navigational Core Overhaul Mod (1.21.1, 1.20.1) – Find Rare Biomes Instantly

Navigational Core Overhaul Mod extends Explorer’s Compass by combining structure and biome tracking into one handy tool. You can search for any generated point of interest across your current dimension without ever leaving your chunk. The mod brings a helpful top-screen direction bar, detailed 3D structure previews, and quick waypoint integration for your travels.

Features:

• Combined Search System: Locates any structure or biome that generates in your current dimension.
• Multi-Target Search: Lets you select multiple targets at once with Ctrl-click to find whichever one is closest.
• Interactive 3D Previews: Displays a rotatable model of structures so you can inspect them before starting your trip.
• Search for whole groups like every village or ocean ruin instead of naming single variants.
• Scans past already discovered places to point you toward the next available one.
• Filter your search list by mod, dimension, or specific keywords to find locations faster.
• A heads-up display shows real-time search progress, coordinates, and exact distances.
• A top horizon direction strip turns green when you face directly toward your target.
• The compass needle smoothly points straight at your chosen location.
• Stores your discovered places so you can share coordinates in chat or track them again later.
• Automatically creates waypoints in Xaero’s Minimap whenever a place is found.
• Runs searches across background threads to keep worlds running smoothly without lag spikes.

Configuration:

• maxRadius: sets how far searches check before stopping.
• maxSearchTimePerTick: controls the slice of server tick time allowed for searching.
• asyncBiomeSearch: runs biome finding on background threads to keep the game smooth.
• asyncStructureSearch: checks structure placement using background threads without loading chunks.
• structureBlacklist: hides specific structures from the list using names or wildcards.
• biomeBlacklist: blocks specific biomes from appearing in search results.
• allowStructurePreview: toggles whether players can open 3D structure preview models.
• showDirectionBar: turns the on-screen horizon direction strip on or off.

How to Use:

1. Hold the compass item in your hand and right-click to open the search menu.
2. Select a structure or biome from the list, or hold Ctrl and click multiple entries to target the nearest one.
3. Click the search button to begin scanning your surroundings.
4. Follow the compass needle or the top green direction strip to travel straight to your destination.
