Script Runtime

Simple interface.
Complex engine.

Prometheon Studio surfaces the complexity of a real-time simulation engine behind one coherent, minimal interface. The system handles rendering, physics, AI generation, and script execution so you focus on what you're building, not how.

One platform that combines an engine, a visual builder, and an AI assistant. No context switching. No integrations.

Intelligence built into
every layer.

Local models run offline on your machine. Cloud models unlock higher intelligence on demand. The system routes automatically.

Free · Offline

Local AI Models

Lightweight models run entirely on your hardware. No internet required. Full privacy. Available on the free tier to every creator.

Create a basic terrain mesh
Generate a physics script
Add a point light at position
Premium · Cloud

Cloud AI Models

Access larger, higher-capability models via cloud compute. Faster scene generation, smarter code, richer context understanding.

Build a forest with dynamic lighting
Create a physics-based rope system
Generate an inventory UI system
Hybrid · Adaptive

Adaptive Routing

The system evaluates task complexity and routes automatically. Simple edits use local. Generative or multi-system tasks route to cloud when available.

Auto-optimize scene for 60fps
Refactor scripting architecture
Generate full game mode logic

Production-grade systems,
unified interface.

Every feature of the engine is scriptable, configurable, and AI-accessible. Built for scale from day one.

⚙️

Instanced Rendering System

GPU-optimized instancing with LOD batching. Render thousands of objects with minimal draw calls and full physics selectively activated per LOD tier.

🌍

Real-Time World Simulation

Scene graph with dynamic streaming, environment system with daylight cycle, weather, fog, wind, and procedural generation pipeline.

🧠

AI Code & Scene Generator

Generate scripts, UI layouts, scene configurations, and debug recommendations directly from natural language inside the editor.

🧩

Visual App Builder

Drag-and-drop component system backed by a live code layer. Hybrid: design visually, extend in C# or JavaScript, export anywhere.

📦

Asset Streaming System

Models, textures, audio, and scripts stream on demand. Asset pipeline supports procedural generation, ServerStorage, and prefab variants.

🔌

External API Integration

Built-in JSON bridge for external tool communication. Connect analytics, cloud services, external databases, and custom tooling via the engine event bus.

🧱

Physics + LOD Optimization

Rapier physics with character capsule, collision detection, trigger volumes, and raycasting. LOD-aware physics activation reduces simulation overhead at distance.

🔒

ECS Architecture

Entity-Component-System core with TransformComponent, VelocityComponent, RenderComponent, and ControllerComponent. Compose any entity at runtime.

🎥

AAA Chase Camera

Third-person camera with collision avoidance, smooth exponential lerp, shoulder offset, sprint FOV boost, and procedural camera shake.


Three ways to build. One system.

Whether you think visually, prefer code, or want AI to scaffold the first draft — all three paths produce the same output and are interoperable in real time.

🖱

Visual Drag-and-Drop

Place objects, configure components, and wire behaviors without touching code. Ideal for scene construction and UI layout.

⌨️

Direct Scripting (C# / JS)

Full access to the engine scripting API with hot reload, real-time debugging, breakpoints, and watch expressions.

🤖

AI-Assisted Generation

Describe what you want. The AI generates the code, scene configuration, or system logic — then you refine it.

A command system that controls
everything.

Every engine system is exposed through a consistent C# API. Define your own commands that interact with physics, environment, rendering, and simulation logic.

engine-commands.cs
// Core engine control
Game.SetGravity(-15f);
Game.SetViewMode("first");
Physics.Pause();

// Environment + lighting
Environment.SetTimeOfDay(21f);
Environment.SetWeather("storm", 0.8f);
Lighting.SetBloom(true, 1.5f);

// Scene manipulation
World.Create("wall", "box", 10f, 2f, 0f);
World.SetColor("wall", "#3a3a3a");
World.Scale("wall", 1f, 4f, 8f);

// Camera + player
Camera.SetFOV(90f);
Camera.Shake(2f, 0.6f);
Player.Teleport(0f, 20f, 0f);
Player.SetShirtColor("#cc2200");
