      Hi everyone,

      I'm having a recent problem with a new file... Vray doesn't render when caustics are on. I hear my computer running pretty hard but the Vray Frame Buffer stays black for hours (yes... I gave up after an hour for a 640px picture) When I check them off, I got an image... Any suggestions?

        Hi
        Can you tell us what settings you are using. for example
        "Caustics Tab"
        -Max photons
        -Multiplier
        -Max Density
        -Search Distance

        "Environment...GI Color Tab
        -Caustic Subdvis
        -Photon radius

        have you followed this tutorial step by step?
