Non-rectangular terrain

I'm trying to create my terrain in CityEngine. I'm using TIFF files for the heightmap and the texture of my terrain. However, a little part of the images are defined as No Data (because I'm missing a part of the Aerial photo that I want to use for the texture of my terrain), so they are not rectangular anymore. When I create my terrain the No Data part is shown black. However, I want to hide this part. The files have the same extent. 

In other words: I want to create a terrain which is not rectangular. Is this possible?
