This is a merge area. It seems that CityEngine does not like the way these roads come together because it won't generate that section. It doesn't do that to every merge area but sometimes it refuses to texture the area. Is there a set of best practices for merge area and ramps?
Yes! It's wierd. The shapes took on InnerPavement for some reason. All of the vectors were assigned what I expected. it does that all over the place but it is much easier to fix in CE than Maya! Thanks! That little double check saved me big!
