I'm wondering wwhat happens to my exported cities. If I create a city and export this model to obj everything is fine. If I open the exactly same scene next day and export again I'll get some failures at the streets. Some sidewalks are missing and I got some holes in my model the houses still looking fine. I tried it with different rules and export settings but it won't work.
So far I evaluated cityengine and it fit's nearly perfect into the workprogress of my company. The last open point is this problem. Hope somebody can help me.
