36 /// \class UsdRenderProduct
37 ///
38 /// A UsdRenderProduct describes an image or other
39 /// file-like artifact produced by a render. A RenderProduct
40 /// combines one or more RenderVars into a file or interactive
41 /// buffer. It also provides all the controls established in
42 /// UsdRenderSettingsBase as optional overrides to whatever the
43 /// owning UsdRenderSettings prim dictates.
44 ///
45 /// Specific renderers may support additional settings, such
46 /// as a way to configure compression settings, filetype metadata,
47 /// and so forth. Such settings can be encoded using
48 /// renderer-specific API schemas applied to the product prim.
49 ///
50 ///
51 /// For any described attribute \em Fallback \em Value or \em Allowed \em Values below
52 /// that are text/tokens, the actual token is published and defined in \ref UsdRenderTokens.
53 /// So to set an attribute to the value "rightHanded", use UsdRenderTokens->rightHanded
54 /// as the value.
