Unreal to Gaussian Splat - Automated COLMAP Dataset Generator

Transform Any Unreal Engine Scene Into a Gaussian Splat Dataset.

Convert Unreal Engine scenes, products, interiors, environments, and props into COLMAP-ready Gaussian Splatting datasets directly inside the Unreal Editor.

No manual COLMAP reconstruction.
No Movie Render Queue setup.
No external command-line workflow.

Just place your capture rig, press capture, and export a dataset ready for Postshot, LichtFeld Studio, Nerfstudio, and other 3DGS trainers.

🚀 What’s New in Version 2.0

Version 2.0 brings a much more powerful and flexible capture workflow:

✅ Product Capture Rigs
✅ Path Capture Rigs
✅ Volume Capture Rigs
✅ Incremental Dataset Capture
✅ CustomDepth Alpha Masks
✅ Optional Depth Maps
✅ Dataset Quality Report
✅ Faster C++ Ray-Traced Point Cloud Generation
 

🎯 Key Features📸 One-Click COLMAP Dataset Export

Capture RGB images, camera poses, and sparse COLMAP files directly from Unreal Engine.
 

🧊 Product Capture Mode

Create object-focused datasets using:

✅ Spherical camera rig
✅ Cylindrical camera rig
✅ Half-sphere rig
✅ Half-cylinder rig

Perfect for furniture, props, products, marketplace assets, and isolated objects.
 

🏠 Volume Capture Mode

Fill rooms or spaces with capture cameras using a configurable 3D volume.

Includes exclusion support to avoid invalid camera positions and improve dataset quality.
 

⚡ Incremental Capture

Already captured your dataset?

Add more cameras later and capture only the new ones instead of rebuilding everything from scratch.
 

🎭 Mask Generation

Export masks/alpha data for product isolation and mask-assisted workflows.
 

🌐 Compatible With Popular 3DGS Tools

Use the exported dataset with:

✅ Postshot
✅ LichtFeld Studio
 

🏎️ Why This Plugin?

Unreal Engine already gives you beautiful lighting, materials, Nanite, Lumen, and high-quality 3D scenes.

This plugin helps you turn those scenes into trainable Gaussian Splatting datasets without the painful technical setup.

For buyers, the biggest value is simple:

✅ Unreal Scene → COLMAP Dataset
✅ No manual alignment
✅ No external reconstruction
✅ No MRQ setup
✅ Faster testing and iteration
✅ Designed specifically for Gaussian Splatting workflows

🎯 Perfect For

✅ Arch-viz artists
✅ Product visualizers
✅ Game developers
✅ Technical artists
✅ Researchers
✅ 3DGS / NeRF creators
✅ Anyone converting Unreal scenes into interactive splats
