Here's my problem: The windows render as a non-transparent black in Lumion.
This is what Lumion says about the problem: "It looks like the windows are inverted surfaces or incorrect Normals resulting in the rendering of light being incorrect." I created the windows in Softplan. In Softplan, is there any way to correct the Normals or change the surfaces so that they are not inverted? In Softplan, is there any way to make sure that surfaces are correct when a window (or other surface for that matter) is created?
The Lumion customer support imported the Softplan .fbx file into Blender and corrected the Normals. They then imported the Blender file back into Lumion and created a render in which the glass was correct. See third picture below.
