Billion-Scale Gaussian Worlds Enter Unreal Engine for the First Time

The first UE solution for billion-scale Gaussians: massive real scenes, loaded in full

The only UE solution that can handle billion-scale Gaussian data today. LCC2's extreme compression loads billion-point 3D Gaussian scenes into Unreal Engine in one piece while preserving high fidelity. Covering hundreds of thousands of square meters of the real world, it brings large campuses, factories, and historic districts into the digital world.

*The real-world area covered depends on scene complexity and the level of scan detail.

Multi-format Gaussian Splat support

Compatible with LCC2, LCC, PLY, SOG, and SPZ Gaussian Splat formats, so your existing 3DGS assets go straight into Unreal Engine with no format conversion. For high-point-count scenes, the native LCC2 format delivers higher real-time frame rates and smoother performance, holding up even in massive scenes: a 50-million-Gaussian scene renders at around 60–90 FPS.

Relighting, now closer to reality than ever

3D Gaussians are relit using the geometry of a same-scale mesh, producing accurate cast shadows, self-shadowing, and reflections. The resulting 3D Gaussian scenes carry controllable, realistic lighting, ready for the LED wall in virtual production.

Create epic, movie-quality shots with DOF

Native depth information gives 3D Gaussians true focus falloff and foreground-to-background layering, not a flat, billboard look. Use depth of field to shape your camera language and build atmosphere for cinematic camera moves and storytelling.

Seamless 3D asset fusion to build the virtual world you want

Real-world 3D Gaussians blend naturally with your existing mesh asset library. Layer, replace, and build freely inside scanned scenes. Each LCC scene ships with a same-scale mesh, collision-ready out of the box.

Built for virtual production workflows

• Slots into your existing pipelineNatively supports Unreal Engine nDisplay and disguise, and can be quickly extended to Unreal-based virtual production platforms like Pixotope and Aximmetry. Real-world 3D assets go straight to the LED wall.
• Code-free Blueprint integrationDrive the plugin directly in Blueprints, lowering the barrier to entry so artists and designers can build and iterate fast.
• Production-grade color pipelineOCIO / ACES compatible, fitting into your existing color-grading workflow for faster, more controllable, more professional delivery.

Stable high frame rates, smooth VR experience

Streaming LoD sustains high frame rates, keeping massive real-world 3D Gaussian scenes stable and smooth in VR headsets. Put on a headset and wander through a fully captured 3D space as if you were actually there. Compatible with PICO, Meta Quest, and other mainstream VR headsets.

One pipeline, from capture and render to deployment

From on-site capture and reconstruction to in-engine render and deployment, the entire pipeline is built in-house by XGRIDS on one unified data format. No switching between multiple tools, or rework from format conversion. Faster to deploy, more consistent results.
