01 Gaussian splats, native to Unreal Engine
Introducing
WallGS.
A high-performance, high-quality Gaussian Splat Renderer for Unreal Engine 5.
Supports Unreal Engine5.3–5.8
Import large Gaussian splat scenes, render them in the Unreal viewport, and generate usable collision without leaving the editor.
/ RENDERING ARCHITECTURE
Spend GPU time where detail is visible.
WallGS organizes splats into spatially coherent clusters at import. At runtime it rejects off-screen clusters before sorting, sends only visible splats through exact GPU depth sorting, and uses screen-space adaptive density to reduce distant work while preserving full density near the camera. Importance-ordered representatives, footprint and opacity compensation, and temporal sort reuse keep that reduction stable—and every optimization can be tuned or disabled per actor.

/ IMPORT BENCHMARKS
Measured scenes.
Visible difference.
These comparisons use the scenes listed below. NanoGS time includes the initial import plus Nanite enable time.
NanoGS data is unavailable for the 33M SOG scene because the test could not be run without .SOG support.
/ VIEWPORT PERFORMANCE
Runtime behavior,
shown side by side.
Recorded directly from the Unreal viewport at 1920×1080 using the 15 million splat Urban Graffiti Alley Night asset.
One-click collision generation
/ COLLISION
One click from splats
to scene interaction.
WallGS can generate collision from a Gaussian splat asset directly inside Unreal. The goal is simple: scans should not be just beautiful backdrops — they should become usable spaces for blocking, tracing, placement, and interaction.
- 01Generate
Create collision from the splat asset without a separate DCC round-trip.
- 02Tune
Adjust voxel size, density threshold, opacity threshold, and cleanup passes.
- 03Use
Keep the scan visible as splats while Unreal handles physics queries through generated geometry.
/ FORMAT SUPPORT
Native .SOG
and .PLY support.
Import .SOG and .PLY Gaussian splat files directly into Unreal Engine. WallGS handles compressed .SOG scenes alongside standard .PLY datasets, so you can use the format that fits each production asset.
.PLY
Standard interchange path
.SOG
Compressed Gaussian splat scenes
The 33M housing-society scene was imported through WallGS in 42 seconds; the NanoGS comparison could not be checked because that path did not support .SOG in this test.
/ WALLGS
Bring splat scans

Fast import, native rendering, SOG support, and collision generation in one workflow.
