A system and method for computing a rendered image of a computer-generated object in a computer-generated scene. A dependency graph is accessed, the dependency graph including a plurality of interconnected nodes including a look-selector node. An asset is accessed at an input to the look-selector node. The asset includes a plurality of looks for the computer-generated object, each look of the plurality of looks corresponding to a different visual appearance of the computer-generated object. At the look-selector node, an active look is selected from the plurality of looks. The active look is passed to a next node of the dependency graph. The rendered image of the computer-generated object is computed having a visual appearance that corresponds to the active look.
