This Enables the Progressive image sampling mode. UI Path: ||Render Setup window|| > V-Ray tab > Render Settings rollout (Renderer set to V-Ray GPU) Progressive & Bucket Rendering Modes It specifies the maximum samples per pixel for refining the image. V-Ray performs adaptive sampling on the image, trying to put more samples into areas that have more noise. A value of 0.0 traces the entire image unconditionally. Higher values allow more noise in the image, while lower values try to reduce the noise. It is a threshold that determines when to stop refining a pixel. The hybrid render engine running on a CPU supports the same features as the regular V-Ray GPU CUDA engine. Meaning, this mode can be used on computers that don’t even have GPUs. 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 This means that they are able to process many tasks simultaneously, unlike CPUs which operate serially.

GPUs are said to be much better at 3D rendering than CPUs because they’re optimized for graphical computations and parallel processing.

The Computer CPU is also listed as ‘C++/CPU’ in the CUDA device list and can participate in rendering (Hybrid rendering). 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. The devices used by the GPU engine to perform the raytracing calculations, can be specified via the menu available on the right Vray GPU, CUDA & CPU modesĮngine switches between the CPU, CUDA(GPU), and RTX(GPU) rendering engine. Here are the 9 Render Settings in Vray for Sketchup. The rendering section of Vray comes with a huge library of materials, presets, and modes to choose from giving the designers a big range of options to select from depending upon the device they are using.

Vray has been one of the most widely used rendering software for sketchup in the past due to its user friendly interface and easy to learn system. (Image Source – Chaos, Vray for Sketchup) Render Settings in Vray for Sketchup
