3DGS / Gaussian Splatting / UE5 Plugin / Point Cloud / Radiance Field / Virtual Production / Digital Twin / NeRF Alternative / Real-time Rendering / VR / XR
LCC Plugin for UE is a production-ready Unreal Engine plugin for loading, rendering, editing, and relighting 3D Gaussian Splatting (3DGS) scenes at billion-point scale — the same technology behind recent breakthroughs in neural radiance fields and photorealistic scene reconstruction.
If you work with 3DGS, Gaussian Splats, point clouds, NeRF-style captures, or photogrammetry and need to bring them into Unreal Engine 5 for real-time visualization, virtual production, simulation, or VR, this plugin is built for you.

3D Gaussian Splatting (3DGS) is a next-generation real-time rendering technique that represents scenes as millions of 3D Gaussian primitives, enabling photo-realistic reconstruction and real-time viewing of real-world environments captured from photos or LiDAR scans. It offers faster training and rendering than NeRF while achieving comparable or better visual quality.
LCC Plugin for UE brings billion-scale Gaussian Splatting worlds into Unreal Engine. Import, edit, relight, and render massive 3DGS scenes in-engine — for film, digital twins, simulation, games, and VR.
Powered by LCC2's extreme compression, the plugin loads billion-point 3D Gaussian scenes into Unreal Engine in one piece while preserving high fidelity, covering hundreds of thousands of square meters of real-world space.
- Film & Virtual Production — Turn real-world 3D Gaussian Splatting scenes into production-ready virtual sets for LED walls. Relight, edit, and add cinematic effects.
- Digital Twins — Create interactive spatial digital twins from captured environments for visualization, design review, and operations.
- Simulation — Build high-fidelity sim environments from real-world 3DGS captures for robotics, autonomous driving, CARLA, and training.
- Games & VR — Convert photogrammetry and Gaussian Splat captures into immersive game levels and VR experiences on PICO, Meta Quest, and other XR devices.
- Architecture & BIM — Combine 3DGS captures with Cesium for geospatial context, or use alongside mesh assets for design review.
- Multi-format 3D Gaussian Splat support: LCC2, LCC, PLY, SOG, SPZ (v2/v3/v4 compatible; SPZ v2 supports Marble-exported Gaussians)
