SC Signature Scanner

Real-time signature identification tool for Star Citizen. Monitors your screenshot folder and automatically identifies asteroids, surface deposits, ground deposits, and salvage targets from in-game signature values.

Version: 4.2.1 Author: Mallachi Game Version: Star Citizen 4.7+

Screenshots

Main Scanner window — Set your Star Citizen screenshot folder, start/stop monitoring, and watch the detection log update in real time as screenshots are processed.

Settings tab — Configure the scan region coordinates, overlay position, popup duration and scale, debug output folder, and save your settings.

Defining the scan region — Opens an existing screenshot. Click and drag directly over the signature value on your HUD to tell the scanner exactly where to look. Only needs to be done once.

Test popup — Preview what the overlay will look like before going in-game. This example shows a Torite (Uncommon) identification at signature 3,900.

About tab — Quick reference for all signature types and ranges, setup instructions, and credits.

In-game overlay — The identification result appears as a small overlay directly over the game while you're flying. The popup auto-hides after a configurable duration.

Features

Core Scanning

• Automatic OCR — Extracts signature values from screenshots using EasyOCR deep learning
• SC 4.7 Per-Mineral Identification — Identifies the dominant mineral of ship-mined rocks by signature value (Legendary through Common tiers)
• Ground Deposit Detection — Distinguishes FPS (3000) and ROC/Vehicle (4000) deposit sizes
• Salvage Detection — Identifies hull panels and wreck debris by size class
• Configurable Scan Region — Define exactly where signatures appear on your screen for faster, more accurate detection

Overlay Display

• In-Game Overlay Popup — Non-intrusive results display over the game
• Customizable Position — Drag-to-position overlay anywhere on screen
• Adjustable Scale — 50% to 200% size scaling
• Configurable Duration — 1–30 seconds display time

Monitoring & Workflow

• Folder Monitoring — Automatically detects new screenshots in your SC screenshot folder
• Test Screenshot — Manually test OCR on any image file
• Detection Log — Timestamped log of all scans and results
• Screenshot Counter — Tracks screenshots processed per session

Quality of Life

• Automatic Updates — Checks for new versions on startup with one-click download
• Debug Mode — Saves OCR processing images for troubleshooting
• Custom Debug Folder — Choose where debug images are saved
• Test Popup — Preview overlay appearance with sample data
• Splash Screen — Loading progress display during startup

Quick Start

For Users (Executable)

1. Download the latest release
2. Extract the SC_Signature_Scanner folder
3. Run SC_Signature_Scanner.exe
4. Configure your scan region in Settings
5. Start monitoring and take screenshots in-game!

For Developers (Python)

# Clone and install
git clone https://github.com/Mallachi/SC_Signature_Scanner.git
cd SC_Signature_Scanner
pip install -r requirements.txt

# Run
python main.py

Note: First run downloads ~115MB of OCR models to ~/.EasyOCR/model/

Usage

1. Configure Scan Region (first time only)

   • Go to Settings → Define Scan Region
   • Take a screenshot with a signature visible
   • Click and drag to select the signature value area
   • Save the region

2. Start Monitoring

   • Set your Star Citizen screenshot folder
   • Click "Start Monitoring"
   • In-game: Press PrintScreen when you see a signature
   • Results appear in an overlay popup

Signature Reference (SC 4.7+)

SC 4.7 replaced the old rock-type system (I/C/S/P/M/Q/E) with a per-mineral signature system. The signature value now identifies the dominant mineral in the rock (40–80% composition). Rocks also contain secondary minerals at lower concentrations.

Ship Mining — Asteroids & Surface Deposits

Tier	Signature Range	Minerals
Legendary	3170–3200	Quantainium (3170), Stileron (3185), Savrilium (3200)
Epic	3370–3400	Ouratite (3370), Riccite (3385), Lindinium (3400)
Rare	3540–3600	Beryl (3540), Taranite (3555), Borase (3570), Gold (3585), Bexalite (3600)
Uncommon	3825–3900	Laranite (3825), Aslarite (3840), Titanium (3855), Tungsten (3870), Agricium (3885), Torite (3900)
Common	4180–4300	Hephaestanite (4180), Tin (4195), Quartz (4210), Corundum (4225), Copper (4240), Silicon (4255), Iron (4270), Aluminum (4285), Ice (4300)

Applies to both asteroids and surface deposits (Prospector/MOLE).

Ground Deposits

100% single mineral per cluster. Signature identifies size, not mineral type.

Variant	Signature	Method
Small	3000	FPS / Hand mining
Large	4000	ROC / Vehicle mining

Possible minerals: Hadanite, Dolivine, Aphorite, Beradom, Glacosite, Feynmaline, Jaclium, Sadaryx, Janalite, Saldynium, Carinite

Note: Large ground deposits (4000) share a signature with Common-tier ship-mining rocks. Context (planet surface vs. space) is required to distinguish them.

Salvage

Type	Signature	Notes
Hull Panels / Active Scrap	2000	Per panel — 2000 × N
Small Debris	1700	Avenger-class wrecks, scrap cargo containers
Medium Debris	1850	Ares Inferno-class wrecks
Large Debris	2400	C2 Hercules-class wrecks
Capital Debris	3000	890 Jump-class wrecks

Collision: Capital debris (3000) shares a signature with FPS small ground deposits. Use context to distinguish.

Undetectable

Vlk Pearls, Vlk Irradiated Pearls, and Flowstone have a signature of 0 and cannot be detected by this scanner.

Troubleshooting

"No signature detected"

• Ensure scan region is correctly configured
• Screenshot must capture the signature value clearly
• Try adjusting in-game UI scale

"OCR not available"

• First run requires internet to download models (~115MB)
• Check ~/.EasyOCR/model/ exists after download

Overlay not visible

• Game must be in Windowed or Borderless Windowed mode
• Check overlay position isn't off-screen

Wrong identification

• Signature 4000 matches Large Ground Deposits, Common-tier ship rocks, and old Surface Deposits — context required
• Signature 3000 matches FPS Ground Deposits and Capital (890 Jump) wreck debris — context required

Slow startup

• Normal — PyTorch/EasyOCR takes 15–20 seconds to load
• Splash screen shows loading progress

Data Sources

• Signatures: Extracted directly from Star Citizen game files (Game2.dcb via Data.p4k)
