This page provides details on the render settings used to adjust the V-Ray GPU renderer.   Overview V-Ray GPU is a separate render engine, introduced by Chaos, that utilizes GPU hardware acceleration. You can additionally use it with your CPU or combine CPU and GPU devices for hybrid rendering. Choosing the V-Ray GPU engine changes the available settings. Refer to the  V-Ray and MAXScript  page for information on how to access the parameters through MAXScript. The Common tab contains no custom or unique V-Ray settings. For more details on the parameters found under this tab, please refer to the 3ds Max help documentation. With V-Ray 6, Hotfix 1, the render settings are now kept when switching between V-Ray and V-Ray GPU. However, note that when switching from V-Ray to V-Ray GPU, the  Samples limit  value is changed depending on the Bucket Image Sampler's  Max subdivs  value. ||Main Toolbar|| >  Render Setup  button and then set  Renderer  to  V-Ray GPU ||Rendering menu|| >  Render Setup...  and then set  Renderer  to  V-Ray GPU ||Render Setup window|| >  Renderer  >  V-Ray GPU Selecting the V-Ray GPU Renderer In order to use V-Ray, you must first select one of its renderers as your current renderer. Open the  Render Setup  window. At the top of the Render Setup window, choose  Production Rendering Mode  as the  Target . For  Renderer , choose  V-Ray GPU . Scenes saved with ActiveShade renderer (a previous GPU rendering workflow) should be switched to use V-Ray GPU as Production renderer instead. V-Ray follows 3ds Max’s conventions for right-click actions on parameter spinners. Right-clicking a parameter spinner sets its value to the minimum allowed. Ctrl + right-click resets the value to its default. Right-clicking a parameter value opens a dropdown menu with an option to reset it to the default. V-Ray GPU Render Settings Tabs V-Ray GPU offers 4 different tabs in the Render Setup window. V-Ray tab Global Illumination settings, Frame Buffer, and Environment settings.
