Tilemap Painter Pro

A complete tilemap painting suite for Unity: paint directly in the Scene view with brushes, 4-way symmetry, procedural terrain, visual RuleTile autotiling, selections, snapshots and prefab placement.

C# editor scripts only (27 source files, full source included, no DLLs).

No native plugins, no third-party dependencies, no network calls.

Editor-only: nothing is added to player builds.

All bulk operations use native SetTilesBlock/GetTilesBlock batch APIs with single Undo groups (Undo.IncrementCurrentGroup).

Package includes demo scene with sample tiles/palette/prefabs, and an automated in-editor paint test suite (Tools > Tilemap Painter Pro > Run Tests).

Verified: clean-project import with 0 errors/0 warnings on Unity 2022.3 LTS and Unity 6000.0; 7/7 editor tests pass on both versions.

Paint tilemaps the way they were meant to be painted — directly in the Scene view.

Tilemap Painter Pro turns Unity's built-in Tilemap system into a fast, artist-friendly level design workflow. No more tiny palette clicks: pick a tile, drag across the grid, mirror your strokes in four directions, generate whole terrains procedurally, and roll back mistakes with snapshots — all without leaving the Scene view.

Key Features

• Scene-view painting — brush sizes 1–5 with live grid highlight, erase, fill and replace modes
• Symmetry painting — horizontal, vertical and 4-way mirroring around a draggable axis, or snap axis to tilemap center
• Procedural terrain generation — multi-octave noise with seed control, 4 biome layers (water / sand / grass / stone), decoration scatter
• Visual RuleTile editor — edit 3×3 neighbor rules with a color-coded grid; autotile edges connect perfectly while you paint
• Selection & clipboard — marquee-select any region, copy, paste (optionally as new), duplicate buildings and patterns in seconds
• Snapshots — one-click version snapshots per tilemap; clear, experiment and restore instantly
• Layer Manager — organize Ground / Decorations / Collision layers, toggle visibility, save and apply layer templates
• Prefab placer — scatter trees, rocks and props with density control inside any painted area
• Export / Import — serialize tilemaps to files for backup or sharing between scenes and projects
• Batch-performance core — all bulk operations use native SetTilesBlock/GetTilesBlock, grouped into single Undo steps

What's included

• Full editor source (no DLLs, no runtime dependencies)
• Ready-to-open demo scene with sample tiles, palette and prefabs
• Built-in test suite — Tools > Tilemap Painter Pro > Run Tests (7 editor tests)

Compatibility

• Unity 2022.3 LTS and newer, including Unity 6
• Works with the built-in 2D Tilemap system — no third-party packages required
• Editor tool only; zero impact on build size and runtime performance

Made for 2D platformer, top-down RPG, city-builder and roguelike developers who paint levels by hand and want the speed of procedural tools without giving up manual control.
