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.
Lets you create geometry in a SOP subnetwork inside this node, so you can create geometry in-place in the LOP network instead of needing a separate SOP network.
