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 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)
