WFC generator

WFC Generator is a pixel art texture generator powered by the Wave Function Collapse algorithm (Overlapping Model). Feed it a small source image and it will learn the local patterns to produce a new, seamless texture that preserves the style of the original.

Built for Minecraft texture pack creators and pixel artists who need variations of 16x16 tiles — but works with any small raster image.

Features

• Overlapping WFC model with configurable pattern size (N=2/3/4), symmetry, and output dimensions
• Batch processing: import a whole folder, generate everything at once
• Drag & drop import from your file explorer
• Real-time progress with ETA estimation
• Regenerate individual results without redoing the entire batch
• Retro ASCII interface with CRT & VHS shader effects
• Runs on desktop (Windows/Linux/macOS) and in the browser
• Single-thread, frame-stepped pipeline for maximum stability

How to use

1. Import one or more source images (PNG, JPG, BMP)
2. Tweak settings: pattern size, output size, symmetry, retries
3. Hit [GEN] — watch patterns collapse in real time
4. Preview results, [Regen] any you don't like
5. [Exp] to export all generated textures
