With Sketchup 8 I can make a simple model and assign a texture like brick to a side. Exporting as a 3D model KMZ or DAE I can see the model with the brick texture in CityEngine. However, any side that was painted with the texture/paint tool as a solid color is still gray in CityEngine. How do I create/model so that I can use a model with solid colored faces on them? I had a similar problem with models that I found on the web as well, say in Google Warehouse.
