FAQ

1. No, it won't become paid. But I appreciate any $$$ support.

2. Yes, windows defender may flag it as suspicious. It even flagged it when I myself downloaded it to test the release page :D Run it through as many virus checks as you want, there are no viruses (said like a true scam, eh?)

3.  No, it's not open source, it's closed source, but I'm open to genuine suggestions.

About

Procedural Tile Generator is a standalone Python application built for pixel artists, indie developers, and game creators who need fast iteration without manually drawing every terrain texture from scratch.

Create seamless procedural textures, recolor them instantly, apply them to tilemaps, generate layered terrain masks, save reusable presets, and export ready-to-use PNG assets for your game pipeline.

Perfect for:

• RPG terrain creation
• Top-down maps
• Platformers
• Sandbox games
• Pixel-art environments
• Rapid prototyping

Features

Basic Generator Mode

Generate seamless procedural textures using built-in patterns:

• Grass
• Water
• Rocks
• Bricks
• Leaves

Supported texture sizes:

• 16×16
• 32×32
• 64×64

Each texture can be generated deterministically using a seed or randomized for rapid experimentation.

Pattern Modifiers

Modify texture appearance while preserving pattern identity.

Available primitives:

• Lines
• Circles
• Noise
• Voronoi
• Clusters
• Outlines

Examples:

• Water + Voronoi → cellular ripple effects
• Grass + Lines → organic blade clusters
• Bricks + Outlines → beveled brick edges
• Rocks + Noise → rough stone variation

Seamless Generation

Supports:

• Edge Wrap
• Rotational Seamlessness

Create textures that tile naturally across large maps with minimal visible repetition.

Rotation & Distortion

Add controlled variation to procedural textures:

• Directional rotation
• Organic distortion
• Natural terrain breakup
• Reduced visual repetition

Tilemap Application

Apply generated textures directly onto bitmap masks.

Included default tilemaps:

• 16×16
• 32×32
• 64×64

Features:

• Region-based masking
• Reverse mask mode
• Organic Edge Spread
• Boundary-aware texture application
• Custom tilemap support

Ideal for:

• Grass borders
• Dirt paths
• Terrain transitions
• Environmental details

Advanced Mode

Advanced Mode allows up to four independent procedural texture channels.

Available channels:

• White
• Red
• Blue
• Green

Each channel can:

• Use procedural generation
• Use a custom uploaded tile texture
• Be enabled or disabled independently
• Use its own tilemap layer

Advanced Mode includes:

• Channel preview system
• Channel status indicators
• Independent tile uploads
• Independent tilemap uploads
• Default tilemap templates for 16×16, 32×32, and 64×64 resolutions

Perfect for layered terrain generation and advanced environmental workflows.

Color Workflow

Built-in palettes:

• Grass
• Water
• Rocks
• Bricks

Customize:

• Base color
• Detail color
• Palette presets
• Color picker workflow
• Eyedropper workflow

Exports remain compatible with external pixel-art tools.
