    Default Iray for Maya 1.6 available for Maya 2016, 2017 and 2018

    Iray for Maya 1.6 is now availabe for Maya 2016, 2017 and 2018.

    You get this version via auto update from our Professional Application Center. Please make sure that you run the latest version of the PAC.

    One remark on this version: We have found an issue with a resulting CPU falback if you have enabled the caustic sampler and your scene includes materials triggering an internal JIT compile of your MDL material.
    In this case you will see a noticable slowdown due to pure CPU rendering. If you encounter this, pls. disable the caustic sampler if you can afford it


    We will fix that very soon. Sorry for the inconvienience

    Features

    Post Denoiser
    Iray Photoreal and Iray Interactive include a new method to reduce noise in generated images.
    A Deep Learning-based denoising filter that operates as a post-process on the rendered image
    and uses additional data from the renderer to guide denoising.

    Volta support
    This version ncludes Iray 2017.1 which offers support of the latest Nvidia hardware

    New BSDF for glossy interaction
    The ifmOpaque materials got a new attribute to define alternative distribution functions for
    glossy light interactions.

    New Fresnel attribute
    The material ifmOpaque, ifmTransmittance and ifmBlender got a new Mode attribute: Fresnel
    (Advanced). This a attribute allows to set the Fresnel Index for each color channel individually.

    ok I could update Iray for Maya 2016 with the PAC but what about Maya 2018 ?
    As this is the first release it can't be "updated", obviously we need to be able to install it at least once, before being able to update it.

    I looked everywhere and couldn't find any Iray for Maya 2018 installer :
    - The PRODUCT DOWNLOAD page in the The Nvidia Licensing Center have not been updated since april 2017.
    - Digital River customer service doesn't work either as it only give access to the installer that where available at buying time.
    - Iray® Plug-In 90 day Trial stops at Maya 2017 ..


    Would you have a clue for this treasure hunt?


    (If we are supposed to wait 3 more days and the new Iray webstore on irayplugins.com, well you guys know how to tease, but this is seriously frustrating.)

    O.k. if you can't wait.
    It will appear in the licensing portal in a couple of days.
    But in the meanwhile use this:
    Linux

    Windows

    Thanks a lot Fuchs,

    I tried with Maya 2016 and 2018 but sadly Iray for Maya 1.6 don't want to use my GPUs to renders so I can't even try the amazing AI denoiser:
    If I disable CPU then " IRAY rend error: Cannot render: found no usable devices. "

    Is there a minimal Nvidia driver version I should use with 1.6 ? (I use 382.33 as recommended by Autodesk certified hardware and it was working very well with 1.5 )

    You need to update your driver, for sure. This version uses a new Cuda version.
    Please use the latest from our website.
