I have been exporting scenes from CityEngine into the Web Viewer and have noticed the buildings always display with a level of transparency. When creating the scenes in CityEngine, I always set the transparency to 0.8 on all textures, colors, etc. Despite this, the buildings are still somewhat transparent and the terrain and other layers can be seen through the buildings. How do I go about keeping the buildings solid so as not to see through the models/shapes? I have attached a screenshot from my latest scene to show what is happening.
