How this service works

Sprite tools: Two terrain textures (grass over dirt, sand over water) to a full 47-tile autotile set with natural, seamless edges, outer and inner corners, plus ready rules: Tiled wang set, Godot 4 TileSet terrains, Unity Rule Tile (editor script), JSON, and a painted preview map. Full schema: https://rengi.dev/v1/sprite-tools/schema

Output

A complete 47-tile autotile spritesheet with natural, seamless edges, inner and outer corners, plus exported rule definitions for Tiled (wang set), Godot 4 (TileSet terrains), Unity (Rule Tile editor script), a JSON ruleset, and a painted preview map showing how the tiles compose together.

Example use cases

Pixel art RPG tilemap terrain

“I have a grass PNG and a dirt PNG for my pixel art RPG — can you generate a complete 47-tile autotile set with crisp edges, the rim outline enabled, 16px tile size, and give me the Godot 4 terrain rules and a preview map?”

Painted-style beach tileset for Tiled

“Generate an autotile from my sandy beach texture on top and ocean water texture below, using soft edges suited for a painted art style, 0.25 edge width, roughness 0.7, and 32px tiles — I need the Tiled wang set output.”

Unity top-down terrain tile generation

“Turn these two textures — snow on top of rock — into a full autotile set for my Unity top-down game: crisp edge style, 64px tiles, roughness 0.3, and make sure to include the Unity Rule Tile editor script.”

When to prefer

Choose this endpoint when you need to generate a production-ready autotile set from exactly two terrain textures for use in Tiled, Godot 4, or Unity — especially when you want seamless 47-tile blob/wang coverage with inner corners, outer corners, and ready-to-import engine rulesets, rather than manually painting tiles or using a generic image processor.

Side effects

Invalid or undecodable base64 image data returns a 400 error
Image URL unreachable or returning non-image content causes fetch failure
Tile size outside 8–256 range is rejected with a validation error
Edge width outside 0.1–0.45 range is rejected
Seed value above 1,000,000 is rejected
Unsupported image format (not PNG/JPEG/WebP) causes a processing error
Top or base texture missing entirely results in a required-field error
