I have created a TIN that I want to add to a CityEngine scene. Can I just add this TIN directly? A problem that we had before was that we wanted a very high level of detail in a small region, but it is part of a much larger region. So I created a TIN that has a much higher node density inside the region of interest than outside of it. I would like to add this to the scene in CityEngine but it seems to only allow addition of a raster. Is it possible to just add a TIN instead?
