Documentation

------------

[Here](https://github.com/jiaozi158/UnitySSReflectionURP/blob/main/Documentation/Documentation.md).

Requirements

------------

- Unity 2022.2 and URP 14 or above.

- Any rendering path.

- Any camera projection type. (perspective or orthographic)

- Multiple Render Targets support. (at least OpenGL ES 3.0 or equivalent)

- [Extra steps](https://github.com/jiaozi158/UnitySSPathTracingURP/blob/main/Documentation/ForwardPathSupport.md#opengl-platforms-extra-setup) are needed for OpenGL APIs.

 

Known Issues & Limitations

------------

- The matrices used to reconstruct world positions are incorrect on XR platforms. (Try porting it to a fullscreen shader graph?)

- The reflection blending is inaccurate on ForwardOnly objects (Complex Lit) in Deferred rendering path. (Not happening in Forward path)

- PBR Accumulation mode doesn't work properly with distortion post-processing effects due to URP limitations. (motion vectors)

- Transparent objects are ignored by reflections.

- Reflections are only computed once. (Ray bounce is 1)
