3DGS Shader Pack for Unity (BiRP & URP & HDRP)

Please read carefully before purchase:

Versions & Platform Compatibility

• Supports Unity 2021 and later. Also tested with Unity 6.2.
• Supports Built-in Render Pipeline (BiRP) , Universal Render Pipeline (URP) and HDRP
• VR performance: URP > HDRP & BiRP. But please keep in mind HDRP only supports linear color space. There is a coversion from linear to gamma if needed.
• [Attention!!] Only supports D3D12 and Vulkan ! Make sure your project has these graphics API enabled.
• In BiRP, only support multi-pass rendering. In URP, support both single-pass and multi-pass.
• Tested build on Windows 11, not fully tested with Android yet!
• OpenXR compatibility (No Meta XR SDK support yet, as Meta XR SDK only supports D3D11 as graphics backend. However, you could use all meta headset features via Meta OpenXR SDK.)
• You will need a powerful PC to run larger scenes, e.g. a room scale environment and generated from World Lab Marble.

Tutorials and Demo:

• Single object import and effects
• Scene import from world lab
• Scene demo 2
• Scene demo with SAM3D generated 3DGS objects
• Full tutorial, including Unity project setup guide and VR setup guide for BiRP
• Full tutorials, including Unity project setup guide and VR setup guide for URP. In VR, URP is 2x faster, as it supports single-pass rendering.



Content Included
