    Default Iray release candidate?

    Hello,

    I wanted to know when we could get a release candidate for Iray 2.3 ? The performance is great.
    Also I wanted to ask if we could have tutorials on decals and bitfrost fluid simulation mesh rendering.
    Thank you!

    Hi Mafioo,

    we have or hopefully had some severe issues with the used Iray SDK included in "Iray for Maya 2.3 Beta". Meanwhile we shifted from Iray SDK 2019.x to Iray SDK 2020.x which also has some nice new features. We hope to release in March with a release candidate quite soon.

    Unfortunately, I don't have tutorials for the mentioned use cases.

    Best

    Thank you so much, I hope the outbreak doesn't affect anybody in front of maya.

    I know this is not a gpu repair website but I broke my titan xp while rendering with the beta version. It work perfect the morning but at night when I tried again there was artifacts and iray would not recognize the gpu it states an illegal memory access.
    I wanted to know, do you think it's a corrupted memory block? Not even video games can work on this gpu anymore (underclocking it work for a few minutes)?
    I really like iray and not even a dead non-professional gpu will put me down.

    Hi Mafioo,

    I am sorry, but we can't help you. As you mentioned we are not repairing GPUs.

    Kind regards
