This is the first image I'm uploading of the city, after I have moved to the newer version of MicroStation. I'm still getting the hang of particle tracing, so no solution of that type was used in this image. I'll start uploading images with that solution once I get it under control and can make good use of it. This image was raytraced, but the newer software seems to do it better and make the textures look better. I'm also glad that it dosen't crash when I create images. If you look closely, you'll see some changes. I've added spiral, twin towers amidst the city. I also added a redesigned train station structure(only a portion visible near the base of the nearest spiral tower) which is an elongated bubble-like structure. I'll do more with that in coming days. Other changes have been done to some materials and the inverted "U" building.
