Live Preview

Preview generated content in real time inside Unreal Engine.

Live Preview connects Ocsidian directly to a running Unreal Engine instance. As the AI generates or modifies content, changes appear in real time in the UE viewport.

How it works

When you open a project, Ocsidian launches a local Unreal Engine session and maintains a persistent connection. Every generation writes directly to the project’s content directory and hot-reloads assets in the running editor.

Preview modes

• Editor Preview — See changes in the UE5 viewport (default)
• Play-in-Editor — Test gameplay in real time
• Standalone — Launch a separate game window

Performance

Live Preview adds minimal overhead to Unreal Engine. Asset hot-reloading typically takes under 2 seconds for material changes and 5–10 seconds for mesh regeneration.
