Hello! I've been running into an issue where exporting my models renders them invisible in Unity. I have also tried to import the .fbx generated by CityEngine into Maya and it is invisible there too.
Not quite sure what is going wrong.
I'm using the "Building_From_Footprint.cga" for buildings that I have drawn shapes for and the "Complete_Street.cga" for the roads I have drawn as well. The buildings generated by the engine have a default rule applied when I got the map data.
I have followed the Esri page on how to export as well as this video with no luck. My scale in Unity is not the issue.
In Unity, I am receiving errors such as:
Next vertex not found in CheckWinding()
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)
And warnings such as:
Mesh 'CityEngineMaterial_6_m' has no normals. Recalculating normals.
A polygon of Mesh 'CityEngineMaterial_m' in Assets/DigiRoc/Roads/DigiRoc_0.fbx is self-intersecting and has been discarded.

Here is a screenshot of my project if it helps. There aren't many textures other than the sidewalks. Some of the more detailed models like that chapel were imported into CityeEngine by a 3D Modeler who hand-made them in Maya. Thank you!
