A system is described that allows a user to create a lineup of alternatives as controls for a part of a 3D scene. Once the alternatives are created, the user can click between them by selecting a desired button and only the alternative selected in that lineup is shown in the scene. The user can create multiple lineups, each for a different part or overlapping parts of the scene, for changing the materials in a scene, and/or for positioning objects in a scene. Alternatives from each lineup can be selected and displayed independently of one another. An alternative in a lineup is created by selecting scene contents and designating a lineup alternative control (An add alternative button) to contain or receive the contents. The lineups and alternatives can be named. The lineups are provided in a graphical user interface (GUI) that displays each alternative as a thumbnail image or swatch control where the swatch image can be a compressed image of the scene containing the corresponding alternative. A user switches between alternatives in a lineup by clicking on a control for a desired alternative. The selected alternative is marked with a visibility indicator indicating that the alternative is the one displayed in the scene. Lineups and alternatives can be modified and deleted.
