    Default v. 2.0 and Iray Server Beauty pass bug

    I have a problem with latest version of Iray+ 2.0 and Iray Server.
    Before latest update I have no issues.
    Issue is in Beauty pass only, other passes are OK.

    This is Beauty pass:

    No problems when rendering locally.
    I just got a couple of renders like that :/

    If I render Beauty pass without Alpha channel - then the pass is OK.
    Something is happen with Alpha channel when file is saving.

    Edit: - sometimes it's happen on PNG files, saved without Alpha channel. Rarely, but it's happen.

    Best!

    Hi Nik,

    I've tried creating my own scene to reproduce this but have not hit the problem so far. Are you using a backplate? Is there anything unusual about the materials or lighting? Are you able to share the scene that you are rendering?

    Thanks,

    Yes, there is a backplate image.
    Email with scene is sent.

    Best!

    Hi Nik,

    Thanks for the scene, I've been able to reproduce the issue.

    It looks like this only happens when you have the denoiser enabled. If it is disabled then the Alpha layer should be rendered correctly.

    It is a bug that that was introduced in Iray 2018.1 so was not present in the last version of the plugin as you say. We will hopefully release an update with Iray 2019.1 in the very near future where this issue will be addressed.

    Thanks for reporting it,

    Thanks Michael!

    Edit: As I wrote - sometimes even without Alpha enabled in Beauty pass - I have those artifacts. Only in Beauty pass.
    It's like in 3 renders happen (beauty pass without Alpha channel, just RGB PNG) from 10 or so renders.
    Just for Info.

    Best!
    Nik
