[XR][Android] Image effects are not rendering properly with single-pass



1) Download project, set up Singleppass stereo capable android device
2) Observe settings are set to Single pass and Daydream
3) Deploy to device
4) Look at the terbuchet thingy in the scene
5) Wait for the image effect to enable
6) Observe that when the image effect is enabled, it renders a small viewport of the post-effectd scene in the top right corner of each eye.


-This happens with each of the standard asset image effects

    I used the @ARKADE fix in Unity 2018.3.4f1 and got the following error. Any advice?

    Shader error in 'Hidden/HxVolumetricDownscaleDepth': 'tex2D': no matching 2 parameter intrinsic function; Possible intrinsic functions are: tex2D(sampler2D, float2|half2|min10float2|min16float2) tex2D(sampler2D, float2|half2|min10float2|min16float2, float2|half2|min10float2|min16float2, float2|half2|min10float2|min16float2) at line 58 (on gles3)

    Thanks @ARKADE your fix works perfectly in 2018.2.5f1.

    FYI to fix any shader with this problem, swap the declaration of the sampler from:

    > uniform sampler2D_float _CameraDepthTexture;


    > UNITY_DECLARE_DEPTH_TEXTURE(_CameraDepthTexture);

    I've got the issue with daydream. Single pass fails on every version 5.6.0f2 onwards.
    Works on 5.6.0f1only.

    A similar issue is produced on GearVR, presumably this happens on all android vr devices. There is an issue in shaders when compiling for single-pass and only for single-pass. "Shader error in '<Shader Name>': undeclared identifier 'sampler_CameraDepthTexture' at <Line Number> (on gles3)"

    Even unity's built in shaders give this error when building. It seems to have to do with the line SAMPLE_DEPTH_TEXTURE(_CameraDepthTexture, i.uv); Hopefully this bug is fixed in the near future, but it seems to be considered lower priority. A workaround IS possible, but since that workaround is either not using post-processing or single-pass stereo, it isn't ideal.
