I'm trying to export shp and terrain data from ArcGIS into CityEngine 2013. The terrain is exported as a height map tiff with the aerial photography as the texture. The problem is that multiple tiff AP tiles makes up the texture, but I can only use a single image as the texture in CityEngine. How can I apply multiple tiles as the texture for the the terrain? Do I need to join them into one single image? Has this changed in CE 2014?
