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. This can be used to composite a background image into the scene and to determine the output resolution. If not used, this defaults to root.format or root.proxy_format defined in the Project Settings. When enabled, add shadows to your render. You can adjust the parameters for your shadows using the Light node’s Shadows tab. When enabled, add reflections to your render. You can adjust the parameters for your reflections using the Reflection node’s Properties panel. When enabled, add refractions to your render. You can adjust the parameters for your refractions using the Refraction node’s Properties panel. 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. Sets the number of pixels to render beyond the left/right and top/bottom of frame, if requested by subsequent operations. Sets the maximum number of specular reflection and refraction bounces PrmanRender uses to trace your scene and make render calculations. Sets the number of samples to render per pixel. Having more samples increases your render quality, but also increases render time. Note:Setting this value to 1 turns antialiasing off. Sets the number of shading calculations for primitives. ![]() This value, along with pixel samples, directly affects your rendering time and the final quality of your results.įor example, a shading rate of 1.0 specifies one shading sample per pixel. A low shading rate value means your render will take more time, but the quality will be very high. ![]() Select the filtering algorithm to use when remapping pixels from their original positions to new positions.Ī high value on the other hand means your render is faster, but the final quality will not be as good. This allows you to avoid problems with image quality, particularly in high contrast areas of the frame (where highly aliased, or jaggy, edges may appear if pixels are not filtered and retain their original values). Impulse - remapped pixels carry their original values.Cubic - remapped pixels receive some smoothing.Keys - remapped pixels receive some smoothing, plus minor sharpening (as shown by the negative -y portions of the curve).Simon - remapped pixels receive some smoothing, plus medium sharpening (as shown by the negative -y portions of the curve).Rifman - remapped pixels receive some smoothing, plus significant sharpening (as shown by the negative -y portions of the curve).Mitchell - remapped pixels receive some smoothing, plus blurring to hide pixelation.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. Lanczos4 provides the least sharpening and Sinc4 the most. Sets the antialiasing method used to filter the pixel samples into the final color. ![]()
