Is there a maximum size of texture files to be accepted by CityEngine? In ArcMap 10.1, I create a new basemap marked "Streets" and export it to an image file and write a world file. When I try to import the image file to CityEngine 2012 using "Texture Import", I get a message saying "You are importing a large image. Downscaling of your image file in your source application is recommended (width and height less than 4000 pixels." How can I export an image file from ArcMap that is the maximum width and height accepted by CityEngine?
