Quickly build game locales in a visual editor. Place objects over map images, adjust their settings, and export to your game engine — no coding, no waiting for a build. In the cloud with your team, or as free files on your desktop.
A layout that "worked in my head" collapses the first time the team sees it. There's nowhere to test an idea before committing to the engine.
Whiteboxing in the engine means builds, scripts, and scene graphs — far too heavy for testing a single corridor layout.
Every layout change costs a build cycle. By the time the level is visible, the design has already drifted from the plan.
Level layouts live in one tool, the world map in another, and the lore in a third. Nobody can see how a dungeon fits the world.
IMSC is the fix: sketch levels in a visual editor over real map images, tune objects without code, and export straight to your engine — all linked to your world and design data.
Upload background map images — dungeons, cities, landscapes — and use them as the basis for level construction. The editor becomes a drawing board over your actual art, not a blank grid.
Define interaction areas, place character spawn points, and mark special zones using intuitive markup tools. The geometry of play is decided here — before a single line of engine code.
Use a ready-made collection of standard game elements — or add your own assets — for quick level filling. Drag objects onto the map and move on; detail work can come later.
Configure the properties of each game object — collisions, triggers, characteristics — through a simple interface. The same structured data powers your levels and your game balance.
Finished levels can be exported in JSON format for use in Unity, Unreal, and Godot. What you prototype here becomes the starting point in the engine — no manual reconstruction.

Prototype and review levels right inside your design workspace — connected to the GDD and the world data around them.
Levels connect to the interactive world map — a dungeon isn't a file, it's a place in your world with lore, characters, and quests.
Connect level objects to items, characters, and mechanics — the level and the data stay in sync by design.
Export levels to JSON in the shape your engine expects — Unity, Unreal, Godot.
Designers, artists, and writers work on the same level live — with roles, access control, and conflict-free updates.
See who changed what, when. Review edits, restore older versions, and keep layout decisions traceable.
