I have been able to get the views and turn them on and off. Each object in the unity scene has a metadata script and there is a KEY called "Layer" which is from the SketchUp model. The SketchUp modeler is collecting multiple SketchUp layers into Sketchup scenes. (In Sketchup a Scene is a collection of "layers".) I'm trying to get access to the scenes (collection of metadata layer names I think so I can turn on a group of objects). However, I can't find this information in the unity objects that reflect is importing. So my question is, where do the scenes end up when they land in unity3d. How would I go about turning on or off groups of layers (as defined by scenes) or is there a better way to use one SketchUp file to load multiple different variations on models as one big master scene?
