1. Do all numeric values in LODs need to display 10 digits? Will Builder choke if fewer digits are displayed?

2. Typically my .obj files do not have polygon normals but they do have vertex normals. Is there a way to determine the polygon normal from these? I was thinking about using the average of the normals of the vertices which define the polygon. Will this work?

3. Does the order of the vertices in a polygon make a difference? E.g., does Open Plane use a clockwise or counterclockwise winding order? How does this order relate to the polygon normal?
