Sets the antialiasing method used to filter the pixel samples into the final color. Lanczos4 provides the least sharpening and Sinc4 the most. Lanczos4, Lanczos6, and Sinc4 - remapped pixels receive sharpening which can be useful for scaling down.Notch - remapped pixels receive flat smoothing (which tends to hide moire patterns).Parzen - remapped pixels receive the greatest smoothing of all filters.
A high value on the other hand means your render is faster, but the final quality will not be as good. A low shading rate value means your render will take more time, but the quality will be very high. This value, along with pixel samples, directly affects your rendering time and the final quality of your results.
For example, a shading rate of 1.0 specifies one shading sample per pixel. Sets the number of shading calculations for primitives. Note:Setting this value to 1 turns antialiasing off. Having more samples increases your render quality, but also increases render time. Sets the number of samples to render per pixel. Sets the maximum number of specular reflection and refraction bounces PrmanRender uses to trace your scene and make render calculations. Sets the number of pixels to render beyond the left/right and top/bottom of frame, if requested by subsequent operations. render camera - take the projection mode from the camera input.orthographic - objects are viewed using parallel projection.perspective - objects in front of the camera have the illusion of depth defined by the camera's focal-length and aperture.When enabled, add depth of field to your render. You can adjust the parameters for your refractions using the Refraction node’s Properties panel. When enabled, add refractions to your render. You can adjust the parameters for your reflections using the Reflection node’s Properties panel. When enabled, add reflections to your render. You can adjust the parameters for your shadows using the Light node’s Shadows tab. When enabled, add shadows to your render. If not used, this defaults to root.format or root.proxy_format defined in the Project Settings. This can be used to composite a background image into the scene and to determine the output resolution. A Scene node that is connected to the objects and lights you want to render, orĪn optional background input.If the camera input is not connected, PrmanRender uses a default camera positioned at the origin and facing in the negative Z direction. The scene is rendered from the perspective of this camera. Inputs and ControlsĪn optional camera input. See also ScanlineRender, Reflection, and Refraction.
In order to use the PrmanRender node, you need to have Pixar's RenderMan Pro Server 20, or earlier, installed and licensed on your machine. With PrmanRender, you have control over aspects like shadows and reflections in your render result. PrmanRender is an alternative to Nuke’s ScanlineRender with additional features for rendering 3D scenes.
PrmanRender ( NukeX and Nuke Studio only) is a render node that works together with Pixar’s PhotoRealistic RenderMan® Pro Server 20, or earlier, to give you an even better quality render result.
