Unity: Status of Image effects and single pass rendering. How can we be successful together?

Unity Engine

Hi,
I wanted to alert the Unity team of a general problem we have been having with Image effects breaking in new ways with each version of Unity. We are currently unsure how to move forward with image effects as each version of Unity has created new issues, and our team is spending hours debugging each version.

While we are having issues with many different image effects, sighting global fog an example of what we have been seeing, global fog has gone though the following progression in the various 5.x versions of unity : Flipping the screen in single pass → Flipping only transparent objects in single pass rendering → Flipping only transparent objects when in multipass → Not rendering correctly in the right eye when using Open VR.

As you see from the above example, we are in a state where image effects are breaking in our project in new ways in each version of the engine. We’ve opened bugs and test cases but don’t have the bandwidth to open bugs for every combination and use case.

Image Effect Video - this video shows some of the strangeness we are seeing with image effects.

Looking at the above video you will see the setup we are using. I have not sent this exact setup in our test projects because:
A) we can show issues in simple scenes with a single camera and only stock unity image effects.
B) our project is huge.

I worry that as we upload test projects your team is fixing the issues shown in the test products but not testing all combinations and thus creating new issues with new combinations of effects.

What I cannot show in video and what we are unable to fix is that many Image Effects do not render correctly in the right eye when using open vr. This is true in a test scene with a single camera and stock image effects. We have workarounds for other issues (though I’d rather these things just worked)

We are unsure how to proceed. What can we change in our process and implementation, and what can we do to help your team be successful in solving the issues we are seeing?

Thanks.

p.s.
Just discovered changing shadows on lights also cause cameras to flip differently. E.g. setting a light from “No shadows” to “Soft Shadows” can actually cause the screen to flip.
