Creates or edits a UsdRenderProduct prim, which represents an output of a renderer (such as a rendered image file or other file-like artifact produced by a renderer), with attributes configuring how to generate the product.
Creates or edits a UsdRenderSettings prim, which holds the general settings for rendering the scene.
Specifies a custom variable computed by the renderer and/or shaders, either a shader output or a light path expression (LPE).
Offsets and/or scales the timing of animation on selected instances.
