Unity editor tools

Build your world, not the busywork.

Romano Assets makes Unity tools that turn slow, fiddly editor jobs into one drag. Each one is built while making a real game, then polished, documented and supported for everyone else.

  • Full C# source
  • No package dependencies
  • Offline docs
All In One Prefab Builder Kit: a city block built from prefab pieces, with a building snapping into place

Products

One toolkit, growing kit by kit

Each kit does one job completely and works on its own. They share a look, a support channel and the same standards.

On the Asset Store

All In One Prefab Builder Kit

Turn any pack of prefabs into a world-building kit. Add a pack, check one review screen, and build with snapping, roads, brushes, fences, street dressing and physics, all from one window.

  • Any pack becomes a kit. Pieces are measured and sorted for you. The pack's own files are never changed.
  • Snap like building blocks. Pieces sit flush against their neighbours, or on the grid.
  • One drag, not a hundred clicks. Roads, rows, splines, fills, fences and street furniture.
Place, snap, keep building: a house snapping into place next to its neighbours, with the Prefab Builder palette

Save and restore player progress, world objects and settings, without code: slots, autosaves, a finished save menu, backups and automatic recovery.

Coming soon

All In One Interaction Kit

Turn your own prefabs into doors, drawers, switches, pickups, keypads and puzzles, with prompts for every controller and a debugger that says why something can't be used.

Title screen, main menu, settings, pause and loading screens for your game, ready to drop in and fully playable with keyboard, mouse or gamepad.

All In One Runtime Building Kit

Let players build bases and place furniture in your game. Turn your own models into build pieces in minutes, and see exactly why a placement doesn't fit.

How every kit is built

Tools you can trust in a real project

  • Full C# source

    Read it, step through it, change it. Nothing is hidden in a DLL.

  • No package dependencies

    Built on Unity's own modules only. Import it and it works; nothing else is installed.

  • Your files stay yours

    Your art packs are never modified, and your own data lives in its own folder, safe across updates.

  • Help inside the editor

    Tooltips on every control, a first-run tour, and offline documentation that ships with the kit.

  • Undo that works

    Every action is one Undo step. Try things freely.

  • Built-in and URP

    Tested on both render pipelines, on current Unity 6 versions, with Domain Reload on or off.

About

Made by a developer, for developers

Romano Assets is Mark Romano, a solo developer making games in Unity. Whenever a job in the editor gets slow or repetitive, I build a tool for it. The tools that prove themselves on my own game, Pawnheads (a co-op physics game about running a tiny pawn shop), get polished, documented and published here.

That means every kit has already been used in a real project before you see it, and the person who wrote it reads every bug report.
