  • Vray 2.0 - Vray RT problems

    Hi there,

    Ive just installed the latest beta of vray 2.0 and have some problems when using VrayRT GPU. As the image renders, blue blocks appear over the screen and change in colour. Also the colours are strange for the entire image. It works fine in CPU mode.

    I have a gtx480 graphics card.

    It was working fine in 3dsmax 2010 when using just vray1.5 sp5 and vrayRT GPU.

    Any ideas ?
    Regards

    Does this happen on any scene? Can you show an image of how it looks. There aren't any major changes between the two versions.

        Ive attached an image to show you what is happening today. I just have a blank yellow screen now when using GPU. CPU is rendering fine still. This is occuring when using max 2011.

        This is max 2011 - just a yellow screen

        As I said, when I had vray 1.5 sp5 and the latest beta of VrayRT GPU, it worked fine.

                  Vlado. Im still having problems with this. I have updated to the latest Vray2.0 build which I assume updates RT as well. I still have different coloured buckets. Im using an entirely different scene.

                    Does it still involve the car paint material?

                      No, a completely different scene with no car paint material used.

                      This is part of the RT window.

                        Ok; which engine is this? GPU, CPU? One machine or many machines with DR?

                          This is the GPU openCL engine. I have 2 480 GTX cards that are not in SLI mode. No other machines are being used. DR not used.

                            Do you get any errors in V-Ray render server window? What is the memory usage on your GPUs?

                              Just checked the server window.

                              Memory usage: 111.94mb

                              Error CL_MEM_OBJECT_ALLOCATION_FAILURE (-4) at line 1716, in file ./src/ocl_tracedevice.cpp !!!

                              Thats the only error.
