Bring Gaussian Splats into Unreal Engine 🚀

WallGS is a native Gaussian Splat Renderer for Unreal Engine, built for bringing Gaussian splats into real-time Unreal projects — from large scanned environments and hybrid 3D scenes to 4D Gaussian Splat animations, PCVR, Android, and standalone VR.

Import .SOG or .PLY splat assets directly into the Content Browser, place them naturally alongside Unreal Engine 3D content, and render them in the Editor and at runtime.

WallGS includes 4DGS playback, TSR, NVIDIA DLSS, Depth of Field, distance-based LOD, runtime optimization tools, collision generation, and dedicated VR/mobile rendering features.

🎬 4D Gaussian Splat Support

WallGS brings animated Gaussian splats into Unreal Engine through 4DGS sequence support.

A sequence can contain individual .SOG or .PLY frames, which WallGS imports and plays as animated Gaussian Splat content inside Unreal Engine. Additional 4DGS formats and workflows are planned for future updates.

🎮 Gaussian Splats + Unreal Engine 3D Content

Gaussian splats do not have to exist in isolation.

WallGS is designed to let Gaussian splats, Static Meshes, characters, props, and other Unreal Engine content coexist in the same scene and produce a visually cohesive result.

With TSR support, splats can be integrated into modern Unreal rendering workflows while conventional 3D geometry retains high-quality anti-aliasing.

WallGS also supports NVIDIA DLSS and Depth of Field, making it easier to create hybrid scenes where traditional 3D assets and Gaussian Splat content feel like parts of the same environment.

⚡ Built for Optimization

Large Gaussian Splat scenes can contain millions of splats, so WallGS includes dedicated tools for understanding and controlling rendering cost.

Distance-Based LOD

WallGS uses a unified distance-based LOD system across:

• Unreal Editor

• Windows runtime

• PCVR

• Android

• Standalone VR

As regions move farther from the camera, their rendered splat count is progressively reduced while preserving overall visual coverage.

Nearby areas retain more detail, while distant areas require less rendering work.

LOD settings can be configured per splat actor, allowing different assets to use optimization settings appropriate for their size and importance.

LOD Coloring

Enable LOD Coloring to instantly visualize which LOD levels are active across a scene.

LOD Coloring can be:

• Enabled directly inside the Editor viewport

• Used during runtime

• Controlled through Blueprints

This makes it much easier to tune LOD transitions while testing actual gameplay or VR experiences.

Live Rendering Statistics

WallGS includes a dedicated "stats wallgs" command for inspecting the renderer in real time.

It provides useful information such as:

• Total splats in the scene

• Splats currently being rendered

• The effect of frustum culling

• The effect of LOD optimization

This provides immediate feedback while profiling large scenes and helps you understand how effectively WallGS is reducing rendering workload.

📱 Android & VR

WallGS includes a dedicated Vulkan mobile rendering path for supported Android devices and standalone OpenXR headsets, including the Meta Quest family.

Android packaging has been successfully tested with Unreal Engine 5.5 and Unreal Engine 5.8. Other supported Unreal Engine versions are expected to work as well.

🧱 Turn Splat Scans into Interactive Environments

WallGS can automatically generate a Static Mesh with complex collision from Gaussian Splat data, allowing scanned environments to become functional parts of an Unreal project.

Generated collision can support:

• Player movement

• Line traces

• Object placement

• Physics queries

• Scene interaction

Choose the preset that best matches your asset:

🏠 Indoor — rooms, corridors, and architectural interiors
🌍 Outdoor — large environments and landscape-scale captures
📦 Object — individual objects and smaller scans

For large environments, WallGS Collision Volumes let you generate collision only where interaction is actually required instead of processing the entire scan.

ℹ️ Important Information

• WallGS is a renderer for existing Gaussian Splat assets. It does not generate or train Gaussian splats from photographs, videos, or Unreal Engine scenes.

• Forward Shading is not supported on Win64. Desktop and PCVR projects must use Deferred Rendering. Android uses WallGS's dedicated Vulkan mobile rendering path.

• Performance depends on target hardware, resolution, project configuration, and splat count. WallGS provides LOD, statistics, VR optimization, and budget controls to help tune projects, but testing on the intended target hardware is always recommended.

• Generated collision is an automatic approximation of the visible scan rather than a hand-authored, watertight production mesh.

• WallGS is currently released as a Beta. Test the plugin with your target project and hardware before production deployment.
