I'm using shapefile vectors to add freeway traffic over my Resampled imagery. I have about 20 different shapefiles compiled into 1 bgl with shp2vec. Everything works as expected but I have one vector line that should be one lane of traffic. The problem is that when the database file is set to 1 lane nothing shows. If I set it to 2 lanes it works just fine. I've tried many different remedies but nothing works. Has anyone ever had this problem?
