      Hello,

      I am having some trouble getting the Vray RT feature to function properly. Every time i try to use Vray RT the "distributed rendering" box switches itself on. Also when the frame buffer shows up it begins to RT render however the sky is not rendered. It just shows as a dark grey.

      I am running Vray RT with a EVGA GTX 970 GPU with the settings shown in the images.

      Can anybody please shed some light on what is happening here?

        My understanding is that you should use CUDA with an NVIDIA card. I would also say that RT on GPU has a few bugs in 2.0 for SketchUp unfortunately.

          great thanks for you answer, i will see how it goes. also when you just do a vray render, does vray use the CPU or GPU? i just bought a new video card (GTX 970) so hoping that it is being used in this case...

            Hello, i am trying to render a png texture to obtain the translucency of polcarbonate. I only have a 50% opacity png in the material's diffuse layer. I obtain very strange marks in the render (as if shadows but i made sure there are no objects that cast shadow). Can you help me please? Thank you.

              If I remember correctly, the normal rendering uses CPU only. RT rendering (when working) can use the GPU (CUDA & OpenCL) or the CPU.

                Do you know if there are any plans for vray to make the rendering engine run on the GPU?
