Somnium Space has always been this open, persistent social universe where users can own land, create avatars and wearables, and shape custom worlds. What truly sets it apart is its fully unlocked C# scripting, with the only real limitation being your world’s storage size.
This means creators aren’t restricted to pre-built tools or limited visual scripting. You can build full games, complex interactive systems, simulations, dynamic environments, and rich social experiences that run live for everyone who visits your world.
Note that Somnium Space works with the following tiers, with strong emphasis on security, flexibility, and support for professional creators.
Blocked (default)
- You can not use C# scripting
Restricted
- You can use C# scripting, but if our tool detects potentially dangerous code, you can not upload
- Pop-up appears for you to request to become Unrestricted
Unrestricted
- You can upload any C#, when people load into worlds they have detailed warnings.
Fully Unlocked
- You can upload any C#, with NO warnings
- This requires our “C# liability” legal document signing, as you will have full access to C# scripting
- Automatically assigned to Studio
To apply for a C# tier, reach out to Somnium Space in the Discord channel #verified_creator_submission and include detailed descriptions of why you need it. The Somnium Space team will then review your request. In any case, the best approach is to first become an active Somnium Space user before requesting.
How C# Scripting Works in Somnium Space
C# scripting in Somnium Space is powered by Unity and the official Somnium SDK. You build (or import) your world in Unity, attach standard C# MonoBehaviour scripts to GameObjects exactly as you would in any Unity project, and then upload it through the SDK. Once live in Somnium Space, those scripts execute in real time for visitors, whether they’re exploring on PCVR or desktop.
Because the C# environment is unlocked once you qualify, you have access to the full power of the Unity engine (physics, particles, animations, audio, UI, coroutines, custom classes, procedural generation, etc.) plus deep integration with Somnium-specific features.
The Somnium SDK and the SDK Bridge
The Somnium SDK is the essential Unity package that lets creators build and publish avatars, wearables, items, and entire custom worlds. It includes everything needed to integrate with Somnium Space’s systems.
A standout feature is the Somnium Bridge (also called SDK Bridge). This system provides ready-to-use components and APIs that “bridge” your Unity world to core Somnium Space modules. It includes components for:
- Video Player
- Trigger Action
- Players Container
- Networking
- Environment control
- And more
It also exposes powerful player-control capabilities (movement, gravity, jump height, teleportation, collision behavior, fly mode, gliding, etc.) directly to your scripts and components.
The Bridge turns C# scripting from “just game logic” into true platform-level power, letting you create custom gameplay mechanics, economy integrations (tip jars, item bridges), interactive installations, and multiplayer-aware experiences that feel native to Somnium Space.
What Can You Actually Build?
The possibilities are genuinely wide open:
- Full games inside your world – obstacle courses, zero-gravity puzzles, custom combat arenas, racing, or social party games.
- Dynamic player experiences – low-gravity zones, custom movement rules per area, teleport pads with logic, or fly/glide modes triggered by story or events.
- Interactive environments – objects that respond intelligently to players, procedural elements, state-driven storytelling, or reactive art installations.
- Economy-integrated worlds – tip jars, wearable/item showcases, or bridges that let visitors engage with the real Somnium marketplace directly from your space.
- Simulations and tools – educational experiences, collaborative creation spaces, or complex systems that would be impossible with limited scripting.
Recent platform updates have made these capabilities even stronger, with new player-control components and performance improvements that benefit heavily scripted worlds.
One exciting recent example is Castle Doom, a partially procedurally generated world launched alongside major SDK enhancements. It demonstrates how C# scripting and Bridge components can power dynamic, large-scale experiences that feel alive and responsive.
Getting Started
Every user gets a free world by default. Download Unity, grab the latest Somnium SDK from the official documentation site, and explore the included world templates and scripting examples.
The official documentation (somniumspace.com/documentation) is the central hub, and the community is active in sharing creations and helping newcomers.
The Bottom Line
C# scripting, supercharged by the Somnium SDK and Bridge, transforms Somnium Space from a beautiful virtual world into a true creator’s canvas. Whether you want to craft a peaceful chill zone with subtle interactive details, a high-octane game, or an entirely new genre of social experience, the tools are there, and the only real limit is your imagination (and storage size).
The platform’s commitment to unlocked C# and deep platform integration via the Bridge puts real power in creators’ hands. With a live economy, wearable and item support, and a growing audience of explorers, now is an incredible time to start building in Somnium Space.
