Unreal Engine 5
WallGS.
WallGS is a high-performance Gaussian Splat Renderer plugin 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 Spatial LOD to reduce distant work while preserving full density near the camera. A quality-first default profile and temporal sort reuse keep the result stable.

Interactive Gaussian splats.
Standalone on Meta Quest.
Try eight interactive splats that you can pick up, throw, and hit with projectiles in an Unreal VR scene with generated collision and physics.
/ Android Vulkan
Support for
Android.
WallGS supports Unreal Engine’s Android Vulkan mobile renderer, bringing Gaussian splat scenes to supported Android phones and standalone Meta Quest headsets.

03Mobile Multi-View
Native mobile path
A dedicated Vulkan mobile rendering path designed for Android hardware—not a desktop renderer forced onto a headset.
Scene-aware budgets
Set an asset-level Android maximum and an optional VR-only spatial cap to balance density, memory and performance for the device you are shipping on.
Built for standalone VR
Mobile Multi-View, stereo-aware visibility and peripheral splat optimization make immersive Android deployment practical.

/ PC VR
Support for
PC VR.
WallGS works with PC VR, supports Instanced Stereo, and includes VR-specific optimization controls for balancing visual quality and performance.

Foveated workloadSTEREO / 2 EYES
/ VR-SPECIFIC OPTIMIZATION
Fewer pixels.
Fewer splats.
Fixed foveated rendering reduces resolution around the edges of each eye. WallGS can also reduce the number of splats processed in those areas, lowering both pixel and splat workload while preserving detail at the center.

/ 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

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.

.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.
