I have successfully added a street network and parcel layer into CityEngine. I have clipped the same extent from a DEM (heightmap) and an aerial image (texture) and exported both images as jpg files with world files. I can successfully import the DEM and aerial only if I used the default projection listed in the pop-up upon import. If I attempt to import the images and select the coordinate system associated with them, they appear as black images behind my street and parcel data. Does anyone have any suggestions as to how I can accurately import my images?
After many tries, I finally figured it out. I realized initially I added my vector data without defining the projection. Therefore, the vector and image data were not lining up even after reprojecting the image in ArcGIS. I started a new scene, added a street layer and defined the projection, then added the image layer and defined the projection. The overlay matched right up. Try and try again until you get it right. Thanks for your feedback.
