Meaning, this mode can be used on computers that don't even have GPUs.
#SKETCHUP RENDERINGS DRIVERS#
Furthermore, you can use the CPU as a CUDA device even if you don't have an NVIDIA GPU and/or NVIDIA drivers installed. The hybrid rendering mode does not require any special drivers. To enable the hybrid rendering mode, simply enable the C++/CPU device from the list of CUDA devices. V-Ray can now execute the CUDA source on the CPU, as though the CPU was another CUDA device. Starting in 3.60, V-Ray GPU can perform hybrid rendering with the CUDA engine utilizing both the CPU and NVIDIA GPUs. Hybrid Rendering with CPUs and the CUDA Engine If you see your CPU listed twice, choose the option with "C++/CPU " in the name. To see if the V-Ray render server is really rendering on the GPU, check out its console output. If V-Ray GPU cannot find a supported RTX device on the system, the process stops. If V-Ray GPU cannot find a supported CUDA device on the system, it silently falls back to CPU code.
#SKETCHUP RENDERINGS HOW TO#
See the sections below to learn how to choose devices on which to run IR GPU. Rendering on multiple GPUs is supported, and by default, Interactive rendering for GPU uses all available GPU devices.
#SKETCHUP RENDERINGS CODE#
Using the Select Devices for V-Ray GPU Rendering you can enable your CPUs as CUDA devices and allow the CUDA code to combine your CPUs and GPUs to utilize all available resources. Hybrid Rendering (running CUDA on GPU and CPU): Starting with V-Ray 3.6, V-Ray GPU CUDA rendering can be performed on CPUs and NVIDIA GPUs at the same time.NVIDIA RTX – Choosing RTX GPU mode works with RTX cards.See here if your card has the minimum required compute capability. Rendering on multiple GPUs is also supported. NVIDIA – The CUDA engine is supported only in 64-bit builds of V-Ray for Maxwell-, Pascal-, Turing-, Volta-, or Ampere-based NVIDIA cards.You can use it with both Progressive and Bucket Sampler types. To enable GPU rendering, from V-Ray Asset Editor → Settings tab → Render rollout, select CUDA or RTX engine. It also supports both the Progressive and Bucket Image Samplers. V-Ray GPU can be used as a production render or in interactive mode to quickly preview scene changes. This is why, it is strongly recommended to not switch between engines in the middle of your project - if you start setting up a scene with the regular V-Ray engine, use it for the entire project. The render settings will only show the available options and your scene will be optimized for GPU rendering. Furthermore, it is not the goal for them to be the same. The supported features of V-Ray GPU running on CUDA and RTX are the same.Īlthough CUDA and RTX share the same user interface as the V-Ray engine, V-Ray GPU differs from the regular V-Ray engine in the way it performs certain calculations. Comparing the results will never come to a one-to-one match, although it may look quite close.
