VoxAI to Unreal Engine
Import AI-generated voxel models into Unreal Engine 5 for AAA-quality games, architecture visualization, and film production.
Why Unreal Engine + VoxAI?
Unreal Engine 5 is the industry standard for high-end games and visualization. VoxAI assets can leverage:
⚡ Nanite
Virtualized geometry handles voxel complexity automatically.
💡 Lumen
Real-time global illumination makes voxels look stunning.
🎬 Cinematic Quality
Perfect for game trailers and virtual production.
🏗️ Arch Viz
Voxel art works beautifully in architectural presentations.
Prerequisites
1. Unreal Engine 5.x
Download from unrealengine.com. UE5 has the best GLB support and Nanite features.
2. VoxAI Model Ready
Generate or select your model in VoxAI. Consider re-voxelizing for your target use case.
💡 Cube Size for Unreal Engine
With Unreal's Nanite technology, you can use high-detail models (small cube size) without worrying about performance:
- •Hero assets: Use 0.022 (maximum detail) for close-up props
- •Environment props: 0.03-0.04 for background elements
- •Stylized look: 0.05+ for intentionally chunky voxels
Step 1: Export from VoxAI
Open View Voxel
Navigate to your model in VoxAI's View Voxel section.
(Optional) Re-voxelize
Adjust cube size based on your asset's role in the scene.
Download .glb Format
GLB is the recommended format for Unreal Engine. It includes mesh, materials, and textures.
Step 2: Import to Unreal Engine
Open Your Project
Create a new project or open an existing one in Unreal Engine 5.
Import via Content Browser
In the Content Browser, click Import or drag & drop your .glb file directly into the Content Browser.
Configure Import Settings
In the import dialog:
- • Enable Generate Missing Collision if needed
- • Check Import Materials
- • Consider enabling Nanite for high-poly models
Drag to Level
Drag the imported Static Mesh from Content Browser into your level viewport.
Leveraging UE5 Features
⚡ Nanite (Virtualized Geometry)
Nanite automatically handles LOD for high-poly meshes. Perfect for detailed voxel models!
To enable Nanite:
- 1. Select your Static Mesh in Content Browser
- 2. Right-click → Nanite → Enable
- 3. Save the asset
💡 Nanite is best for props and environment. For characters, use traditional LODs.
💡 Lumen (Global Illumination)
Lumen provides real-time GI that makes voxel art look incredible with natural light bounce and reflections.
To enable Lumen:
- 1. Open Project Settings
- 2. Search for "Global Illumination"
- 3. Set Dynamic Global Illumination Method to Lumen
- 4. Set Reflection Method to Lumen
Material Tips
🎨 Base Material
VoxAI exports include basic materials. For better results, create a master material with roughness/metallic variation.
✨ Emissive
Add emissive materials for glowing voxels (eyes, magic effects, lights). Works beautifully with Lumen.
📐 Pixel-Perfect Edges
For crisp voxel edges, disable texture filtering: Set texture's Filter to Nearest instead of Linear.
Use Cases
🎮 Indie Games
Create unique voxel-style games with AAA rendering quality.
🎬 Virtual Production
Use VoxAI assets for stylized backgrounds in film/TV.
🏗️ Architecture Viz
Create voxel-style presentations for playful architectural concepts.
🎥 Game Trailers
Leverage UE5's cinematic tools for stunning voxel game trailers.
Troubleshooting
GLB not importing?
Ensure you're using Unreal Engine 5.0+. For UE4, convert your GLB to FBX using Blender first.
Materials not showing?
Check that "Import Materials" was enabled during import. You may need to manually assign materials in the Static Mesh details.
Model scale is wrong?
Adjust the Import Uniform Scale in the import settings, or scale the actor in the Details panel after placing in the level.
Nanite not working?
Nanite requires UE5 and doesn't work with skeletal meshes. For static props, right-click the asset → Nanite → Enable.
