[XR SDK] SSAO Pro from Asset Store is broken/inverted when Single Pass Instanced rendering mode is used
Reproduction steps:
1. Open the attached project ("ShaderRepro.zip")
2. Open the "SampleScene" scene
3. Enable MockHMD XR plugin (Project Settings -> Mock HMD Loader)
4. Set MockHMD Stereo Rendering Mode to Single Pass Instanced
5. Enter Play mode
Expected result: SSAO Pro effect behaves as in Multi Pass Stereo Rendering Mode
Actual result: SSAO Pro effect is broken/inverted
Reproducible with: XR SDK 3.2.17 2019.4.16f1, 2020.1.17f1, 2020.2.1f1, 2021.1.0s10
Not reproducible with: 2018.4.30f1 (XR SDK not available)
Tested:
- Oculus Rift S
- MockHMD

We've identified the issue preventing the correct generation of the depth normals texture. A fix will for Unity will follow.
Note that in order to use single-pass instanced, you need to fix your shader code with the following edits in order to correctly sample from texture-array :
//sampler2D_float _CameraDepthNormalsTexture;
UNITY_DECLARE_SCREENSPACE_TEXTURE(_CameraDepthNormalsTexture);
//half4 nn = tex2D(_CameraDepthNormalsTexture, UnityStereoTransformScreenSpaceTex(uv));
half4 nn = UNITY_SAMPLE_SCREENSPACE_TEXTURE(_CameraDepthNormalsTexture, UnityStereoTransformScreenSpaceTex(uv));
