54 ///
55 /// A UsdRenderProduct describes an image or other
56 /// file-like artifact produced by a render. A RenderProduct
57 /// combines one or more RenderVars into a file or interactive
58 /// buffer.  It also provides all the controls established in
59 /// UsdRenderSettingsBase as optional overrides to whatever the
60 /// owning UsdRenderSettings prim dictates.
61 ///
62 /// Specific renderers may support additional settings, such
63 /// as a way to configure compression settings, filetype metadata,
64 /// and so forth.  Such settings can be encoded using
65 /// renderer-specific API schemas applied to the product prim.
66 ///
67 ///
68 /// For any described attribute \em Fallback \em Value or \em Allowed \em Values below
69 /// that are text/tokens, the actual token is published and defined in \ref UsdRenderTokens.
70 /// So to set an attribute to the value "rightHanded", use UsdRenderTokens->rightHanded
71 /// as the value.
