When CUDA/RTX is chosen as a rendering engine, all unsupported options are disabled from the parameters. |
Auto. Settings – Sets predefined optimal settings. Progressive RPP – When enabled, IPR starts rendering the image with a lower Rays Per Pixel value and then progressively increases it. This speeds up the initial preview of the image. Undersampling – When enabled, V-Ray IPR starts rendering the image at a lower resolution in order to speed up the initial preview. Later the image is rendered at its final resolution. Ray Bundle Size – These control the number of rays that are sent to the IPR render servers for processing when using V-Ray IPR, running on CPUs or GPUs respectively. When using distributed rendering, the smaller sizes cause more frequent client/server communication with smaller network packets thus decreasing the speed of the renderer but increasing the interactivity and vice versa. Note that this number is not the exact amount of rays, but is proportional to it. It is not recommended to increase this value beyond 512. Rays Per Pixel – The number of rays that are traced for each pixel during one image pass. The greater the value, the smoother the picture from the very beginning of the rendering with GI, but interactivity may be significantly diminished. Increasing this value also reduces amount of data transferred from the render servers back to client machine. |
