  • Maya 2014 + Vray 2.4 - batch render - cpu at 20% max

    Hi all,

    I'm rendering out an animation in Maya with Vray. I already have rendered out the prepass (Animation prepass - mode). When I was rendering the prepass, vray only used about 17 to 20% of my CPU and I thought that was probably normal with the prepass. (it took 2 days)

    When I now try to render in the "animation (rendering)" mode, vray uses 17 to 20% as well. So I now know that this is wrong. Renders are taking 1 tot 1.2 hours instead of 10 minutes.

    My system:
    i7-3930k (6 cores, 12 threads)
    GTX 770
    Asus P9-X79 Pro
    32 Gb DDR3-1866
    Windows 8.1 pro 64bit

    When I set the mode to Single frame, it uses the full 100% of my CPU.

    I made sure that under settings "max render threads" is set at 12 and "low thread priority" is disabled. Both did nothing.

    How can I speed up the batch render? I have 1020 frames to be rendered and with a hour per frame at least... it's going to take at least 43 days...

    Do you have any displacement or subdivision surfaces? Fur, grass, proxies?

      No displacements, subdivision surfaces, grass, fur or proxies.

      Also static, not dynamic.

      When I set the render mode to single frame, Vray starts to render with all my threads again.

        This is very odd. I suppose it would be best to send us the scene over to vraymaya@chaosgroup.com to debug what's wrong.
