TileSnap

Generate tileset transitions between two terrains.

Drop in two seamless textures. Get a complete transition tileset back. Built for fast prototyping.

Desktop app (Windows · macOS · Linux)  ·  PNG + Godot 4 export

Try it free in your browser, above. The demo is the complete tool — nothing is locked. Exported images carry a watermark; the desktop app exports clean, watermark-free tilesets.

How it works

1. Drop two textures. Grass and dirt, sand and water — anything seamless.
2. Pick a pattern. Wang edges, Godot blob, dual-grid, or build your own.
3. Shape the transition. Sliders for curve, noise, and texture effects.
4. Export. PNG atlas, Godot 4 .tres, or full project bundle.

What it does

Vector-based edges The boundary between your two terrains is fully editable, and every slider updates the preview in real time. Organic noise + corner softening Waves along the edge Dual-layer patches — carve holes, add fills

Built-in patterns + custom layouts Common tileset layouts out of the box, plus a template editor for everything else. Wang edges, Godot blob, dual-grid Template editor for your own grid Terrain mode picked per pattern

Per-tile control Fix orientation and add variety without re-importing anything. Rotate or flip individual tiles Multiple randomized variants per tile Repeated terrain stops looking stamped

Export

• PNG atlas for any engine
• Godot 4 .tres + PNG with terrain peering bits (tested on 4.6)
• Project file (.tilesetproj.json) to keep editing later
• ZIP bundle with everything

In the free browser demo, exported images include a watermark. The desktop app exports them clean.

Bundle mode (Godot 4)

Combine multiple projects into one TileSet. Each project keeps its own texture as a separate atlas source, all wired into a single .tres sharing one terrain set. Terrains match by name — grass in grass↔dirt, grass↔stone, and dirt↔stone all collapse to one terrain ID.

Notes

• Desktop only (min 1024px width)
• Early version — rough edges expected, feature set still evolving
• Downloads aren't code-signed — on Windows click More info → Run anyway; on macOS right-click the app → Open (or run xattr -cr).
