WallGS Releases Plugin for Rendering 3DGS and 4DGS in UE5 on Fab
WallGS is a Gaussian Splat renderer for Unreal Engine 5.3 to 5.8, with PLY and SOG support, 4DGS, Quest support and collision generation. The higher-tier WallGS Pro adds features such as relighting.

Key points
- This plugin natively renders 3DGS and 4DGS in UE5 and can load PLY and SOG v2 files.
- It supports Windows, PCVR, Android and Meta Quest, and includes load-adjustment features such as spatial LOD and DLSS.
- The "color mesh generation" mentioned in the post could not be confirmed in the source material. What could be confirmed is collision mesh generation.

What happened
WallGS is a plugin that renders Gaussian Splats (3DGS) in Unreal Engine 5.3 to 5.8. According to the official website, there are two editions, the standard WallGS and the higher-tier WallGS Pro, and both are available on Fab. The developer is listed as Walhar Gohar on the official page.
How it works
WallGS is a dedicated renderer for existing Gaussian Splat assets. It has no function for training or generating splats from photos or video, and the official page states this explicitly.
By the numbers
| Supported engine | Unreal Engine 5.3 to 5.8 |
|---|---|
| Supported formats | SOG v2, binary little-endian PLY (3DGS / 4DGS sequences) |
| Supported platforms | Windows/PCVR, Android/Meta Quest (Vulkan, OpenXR) |
| Common to both editions | 3DGS/4DGS rendering, LOD control, collision generation |
| Pro only | Relighting (experimental), Lumen screen-trace reflections, runtime import/advanced viewer, advanced 4DGS controls, culling volumes, stochastic rendering |
| Import speed (announced value) | 10.3x faster than NanoGS on average across 5 scenes, with UAsset size 36% smaller |
| Largest test scene (announced value) | A 33M-splat SOG imported in 42 seconds |
| Viewport video | 1920×1080, scene with 15 million splats |
| Win64 limitation | Requires Deferred Rendering (Forward Shading not supported) |
Why it matters
In real-time production with UE, a practical question is whether scan results can be placed in the same scene as ordinary meshes and characters. WallGS provides depth of field, integration with Lumen reflections, and collision generation. This adds options for testing prototypes of games, virtual production and VR experiences that use real-world scans.
How to try it
- Get the free demo for Windows or the Meta Quest APK from the official website, then load your own PLY/SOG files to check how they run.
- Check the feature differences between the standard edition and Pro on the Fab page, and choose the edition that has the features you need (relighting, runtime import, etc.).
- Switch spatial LOD profiles in UE and check the rendering load with stat wallgs.
Caveats and open questions
- The X post mentioned a "feature to generate color meshes from 3DGS," but the only thing confirmed in the source material is Static Mesh generation for collision. A feature that generates colored meshes could not be confirmed from the material.
- According to the official page, the automatically generated collision is an approximation of the visual scan, not a hand-built watertight production mesh.
- The benchmarks are values announced by the developer. The comparison target is NanoGS, and there is no data for the 33M SOG scene because NanoGS does not support .SOG. Details of the measurement environment are not given in the material.
- Relighting is described as an experimental feature.
- Price, last update date and change history could not be confirmed from the material. Fab has only one rating.
- Deferred Rendering is required on Win64. Performance is said to depend on hardware, resolution and data scale.
Glossary
- SOG
- A file format that compresses Gaussian Splats to make them easier to carry around. This plugin supports v2.
- 4DGS
- Gaussian Splats that change over time. Motion is expressed by playing back per-frame data.
- Lumen
- Unreal Engine 5's system for real-time global illumination and reflections.
- Spatial LOD
- A technique that reduces rendering load by lowering splat density at a distance, for each spatially divided chunk.
