Hi there! I created an XPack with something like 80 buildings from Google Earth that I needed for my track (all of them were "optimized" in SketchUp, meaning, I deleted all of the faces that won't be seen in-game to save on loading times). When I placed them on the track, they all looked fine in BTB, but when I tested the track in rFactor, some of the textures appear as if they are on the wrong side of the face. This means that some objects are invisible when driving forward, but I can see them perfectly in my rear view mirror... or the texture is in the inside-of-the-building face of the wall instead of the outside :frown: Help please?? Thank you!!!
