  • Same results possible between V-Ray CPU Production Renderer and CUDA CPU + GPU?

    Hi,

    I am having trouble in achieving the same results between CPU only production renderer and CUDA CPU + GPU renderer, mostly in AA and noise. Is this to be expected?

    Thanks,

    Yes, even though CPU and CUDA engines are like a render brothers they are completely different render engines after all.
    Their settings are different and even though they might generate a very similar render output, they do it in a completely different way.
    Noise differences means that one of the engines has AA settings that produce a better quality image, if you increase those settings for the other engine you should be able to get a similar noise level image.
    If you have difficulties to get the same quality, please pack the scene and send it over for investigation.

      Ah, understood!

      Are all the same features from CPU Production Renderer available for CUDA CPU + GPU?

      Thanks
