When I import a 3D shape model from another software, CityEngine views these models in project correctly.
But I want to publish these models on web scene, because of the face normals of the polygons, 3d models seems to be partially.
I can not change all of the polygon's face normal one by one manually.
Whole polygons are separate, they are not combine building by building
How can I correct the face normal automatically on the building models from inside to outwardly?
In general, this process can not be done 'all automatted', neither in CityEngine nor in any other application. Reason for this is that it depends heavily on the model itself and on the polygon-connectivity.
Of you have a cube, where each side has been moved 'out' a bit, so all the faces are disconnected: How is the computer to know what's inside and what's outside if it's just 6 separate polygons ? :) That makes the task very difficult.
