  1. We are migrating the Unity Forums to Unity Discussions. On July 12, the Unity Forums will become read-only.

    Please, do not make any changes to your username or email addresses at id.unity.com during this transition time.

    It's still possible to reply to existing private message conversations during the migration, but any new replies you post will be missing after the main migration is complete. We'll do our best to migrate these messages in a follow-up step.

    On July 15, Unity Discussions will become read-only until July 18, when the new design and the migrated forum contents will go live.


    Read our full announcement for more information and let us know if you have any questions.

    SinglePassStereoRender causes multiple narrow copies of the view in Rift/Vive and desktop.
    It also kills the frame rate.

    Ok, doesn't happen on a new project only on my existing one. I'll see if I can track it down.

    This seems to be the result of camera image effects.

    Right. With this enabled option you get a doubling of the image for each of:
    Tonemapping
    Antialiasing
    and
    SE Natural Bloom
    Maybe others but those are the ones I use.

    On HTC Vive single pass stereo does not play nicely with Static Batching (artifacts pop up in one of the eyes when enabled)

    I am also seeing the skybox in the right eye being transformed differently than in the left one. This is using "Viking Village" as a test level so perhaps the extra water reflection cameras are causing this.

    @Cross22, Thanks for the feedback and info.

    I will reproduce the first issue and pass it on to the devs and the second is a known issue.

    It's worth noting that the water reflection shader used in the Viking Village test level inherently does not work with VR, but you are correct, the right eye is being transformed differently when Single-Pass stereo is enabled, and the skybox horizon is the easiest way to see the problem.

    So far I have only been able to notice this 'Incorrect-right-eye transform' issue on HTC Vive with single pass stereo enabled but apparently is reproducible on other devices as well.

    Single-pass stereo is in an experimental phase of development now so I thank you so much for your patience and your feedback. We will get these problems solved and get you those performance gainz!!

    Yeah I have 2 image effects going on my camera and I get 4 views.
    Unity built in Bloom and a custom edge detect.
