The complete QR toolkit: 42 Blueprint nodes for styled generation (colors, gradients, logo), real in-engine decoding from textures/render targets/files, Micro QR, WiFi/vCard/SMS content nodes, PNG + SVG export, batch & async, UMG live-preview widget. UE 5.1+, no C++ required.

Preview documentation: debstudios.com/ProQRCode_Documentation.pdf
Example DEMO - 5.7

Event tickets, kiosk screens, in-game item sharing, AR markers, server pairing codes - QR jobs always end up the same way: an external tool, an imported texture, and no way to read codes back at runtime. Pro QR Code does the whole job inside the engine, in single nodes.

42 HAND-CRAFTED BLUEPRINT NODES - 5 LIBRARIES + 4 ASYNC ACTIONS

The only plugin on Fab that both GENERATES styled QR codes and actually DECODES them in-engine.

📷 REAL IN-ENGINE DECODING (unique on Fab)

- Decode from Texture2D, Render Targets (scene captures!) and image files

- Rotation, perspective, inverted colors, styled modules, logos and noise tolerated

- Full Reed-Solomon error correction + mirrored-symbol support

- Works in packaged games, kiosks and VR - no phone camera app tricks

🎨 STYLED, BRANDED CODES THAT STILL SCAN

- Colors, transparent backgrounds, square / rounded / dot modules

- Two-color gradients (4 directions) and custom finder-eye colors

- Logo embedding with automatic background clearing

- 6 ready-made presets + a validator that flags scannability risks before you ship

🔳 MICRO QR (M1-M4)

- Tiny 11x11-17x17 symbols for part labels and compact payloads - one option switch

📡 CONTENT NODES - NO MORE HAND-BUILT STRINGS

- WiFi join (scan to connect), vCard & MeCard contact cards, email, SMS, phone call, map location, WhatsApp chat, calendar event, URL - all correctly escaped, one node each

📤 EVERY OUTPUT FORMAT YOU NEED

- UTexture2D for materials and UI, PNG file or in-memory bytes

- SVG string/file for infinitely scalable print exports

- Raw module matrix for custom 3D / mesh / decal visualizations

- Batch generation + async batch PNG export with per-file progress

⚡ ASYNC EVERYWHERE IT MATTERS

- Generate, save and decode on worker threads - never hitch a frame

🧩 UMG WIDGET WITH LIVE PREVIEW

- Drop the Pro QR Code widget into any UserWidget and tune your style visually in the Designer - no PIE required

🧰 EDITOR INTEGRATION

- Bake QR Texture Asset: create real Texture2D assets in the Content Browser from Editor Utility Widgets

🛡️ SAFE BY DESIGN

- Every node returns success + a clear error message - never a silent failure, never a crash

- Built-in self test: run ProQR.Test in the console any time - 96 checks

- Encoder and decoder written from the ISO/IEC 18004 specification for this plugin and verified against three independent reference implementations - no third-party libraries, no licensing baggage

Honest scope notes: decoding supports standard QR symbols (Micro QR is generate-only); extremely angled photos of very large symbols may need a straighter view.
