Hi, since i've been frustrated by the fact that there are some nice mountain tracks out there but with no cameras at all, i've been doing some "basic" TV cameras for several of those tracks. Though you won't find them here to download, you can get them pretty easily.
Here's one for Usui, it includes fast_lane.ai and one replay camera set.
