I did a noob build of Houston track. Its not great, has some kinks and not highly decorated, but then again no one else has made this local track! Looking for talented folks to pick this up and make it better!
I had to rename "msr_houston.kn5" to "msr_houston_1.kn5" in order to match the folder name to get it to load, and there might be a few gaps in the mesh where the car can fall off, but a good first build.
