!Path Tracer Heatmap

🗺️ Path Tracer

See exactly where you've been. Path Tracer renders a real-time color heatmap overlay on the ground showing your most-traveled routes — no commands, no maps, just a live visual layer on your world. NEW: Explorer Mode shows a color coded path of your walking history – great for caving & complicated areas!

How It Works

Every block you walk on gets tracked. The more you travel over a spot, the hotter its color becomes:

Path Mode

• 🟢 Green → lightly traveled
• 🟡 Yellow → moderate use
• 🟠 Orange → frequent path
• 🔴 Red → heavily worn route

Tiles below your minimum threshold stay invisible, so only your real paths show up. Path Tracer records the block you're standing on plus the 8 surrounding blocks with each step, creating a natural-looking footprint rather than a single-block trail.

Explorer Mode

• 🟢 Green → walked in the last 1 day
• 🟢🔵 Cyan → walked yesterday
• 🔵 Blue → walked 2 days ago
• ⚫️ Dark Grey → older paths

The path gradient can be adjusted from 1 - 14 days, stretching out the gradient progression. Dark Grey is always your oldest paths.

Features

• Live heatmap overlay — updates as you walk, no reload needed
• Fully configurable via Mod Menu — adjust min/max walk counts, render radius, and how long data persists
• Option to set Clear Area keybind (clears out paths within a radius of the player)
• Set keybinds to enable/disable (H), switch modes, & remove paths near you
• Ability to track movement for all loaded players in multiplayer (for building paths for shared builds)
• Client-side only — works on any server, no mod required server-side, no world modifications — purely visual.
