Scene Generation

Create complete Unreal Engine scenes from natural language descriptions.

Scene Generation is Ocsidian’s primary creative tool. Describe an environment, and the AI produces a fully realized Unreal Engine level with geometry, lighting, materials, and atmosphere.

Writing scene prompts

Effective scene prompts include:

• Setting — The type of environment (interior, exterior, urban, natural)
• Time and weather — Time of day, season, atmospheric conditions
• Key landmarks — Important structures or features
• Mood — The emotional tone (eerie, peaceful, chaotic)
• Scale — Approximate size and scope

Example

A neon-lit cyberpunk alley at night. Rain-slicked streets 
reflecting holographic advertisements. Steam rising from vents. 
Small ramen stall on the left with warm interior lighting. 
Narrow, claustrophobic, about 50 meters long.

Scene components

A generated scene includes:

• Static mesh actors for structures and props
• Landscape actors for terrain
• Directional, point, and spot lights
• Post-process volumes for atmosphere
• Particle and Niagara systems for VFX
• Sound cues and ambient audio actors
• Navigation meshes for AI pathfinding

Modifying scenes

After initial generation, use follow-up prompts to add, remove, or change elements. The AI understands spatial references like “near the fountain”, “on the second floor”, or “behind the player spawn”.
