Multiple raster files as terrain texture

Discussion created by Sivakanesh on Jun 18, 2014
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?
