A system that allows a user to create a lineup of alternatives as controls for a part of a 3D scene by selecting scene contents and designating a lineup alternative control to contain or receive the contents. Once the alternatives are created, the lineups are provided in a graphical user interface (GUI) that displays each alternative as a compressed image of the scene containing the corresponding alternative. The user can click between the alternatives by selecting a desired button so that 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.
