Google Earth adds shading to all SketchUp models to make them look more realistic. For something like my sky-dome model this is problematical because it means the texture is unevenly lit and too dark. With some very minor editing of the Google Earth ( COLLADA ) model file in a text editor, it’s possible to turn this shading completely off for individual textures. This was exactly what I did for the Skydome Google Earth file posted a couple of days ago. The split-screen picture shows the before and after. The original is on the left.
