Compatibility Inquiry: Does GaussianSplattingVRViewerUnity Support DX11 for Meta Quest Link + Meta XR Plugin?

[wcflaiHKMU]

Hi maintainers,

We’re evaluating your GaussianSplattingVRViewerUnity plugin for a VR project targeting Meta Quest Link using the Meta XR Plugin . However, we’re constrained by the following limitations:

• The Meta XR Plugin only supports DX11 rendering
• Quest Link requires DX11 compatibility for streaming

Our question:
Is GaussianSplattingVRViewerUnity compatible with DX11-only rendering pipelines?

Specifically, we’d like to know:

Are the Gaussian Splatting shaders/materials in this plugin compatible with DX11 (e.g., compute shaders, texture formats)?
Has the plugin been tested with VR headsets like the Meta Quest Pro via Quest Link ?
Are there VR-specific optimizations (e.g., reduced particle count, simplified shaders) to ensure smooth performance on DX11-only workflows?
Any known issues or workarounds for integrating this plugin with the Meta XR Plugin ?
Environment:
Unity version: 2022.3.34f1]
Meta XR Plugin version: 76.0
GPU: RTX 4090
OS: Windows 11
We’d greatly appreciate confirmation of DX11 compatibility and any guidance for optimizing this plugin for VR applications constrained to DX11.

Thanks for your work!

Regarding your questions :

Is GaussianSplattingVRViewerUnity compatible with DX11-only rendering pipelines?

Yes this plugin is compatible with DX11, but a CUDA (nvidia) compatible device is needed.

On the other hand, the unity scripts using the plugin's is only compatible with built-in pipeline. if you want to use other pipeline you have to adapt the scripts in the unity project.

Are the Gaussian Splatting shaders/materials in this plugin compatible with DX11 (e.g., compute shaders, texture formats)?

Yes but the main part of the project is developped in the CUDA pugins. All Gaussian rendering are done in CUDA not is Shaders, Shaders in the projects are only here to, retrieve depthmap of classic 3D render and mix Gaussian result with classic 3D.

Has the plugin been tested with VR headsets like the Meta Quest Pro via Quest Link ?

It works with a Quest 2 via Quest Link so it should works with Meta Quest Pro but it's not tested.

Are there VR-specific optimizations (e.g., reduced particle count, simplified shaders) to ensure smooth performance on DX11-only workflows?

No there is no spécific optimisation done in this plugins, only basic camera clipping is done during Gaussian rendering in the CUDA plugins part.

Any known issues or workarounds for integrating this plugin with the Meta XR Plugin ?

No.
