well there will not be a proper track for a very long time as it is impossible to vreate a new track at the moment!I won't be too much cruel today but you should take more attention to what I'm saying everywhere about Track making.
Before 3DEditor v11, it could be half true because cc-line was a great miss to be able to edit tracks but since v11, it's no more (whatever v11 own bugs).
So OK, literaly, you can't create a track from zero, but you can completely redefine a track.
3DEditor is not perfect and it's not a modeler either, so it's a somewhat long process depending on the changes you want to add.
The matter yet is not that we can't build track, but that nobody want (or can't I know) take the time to build tracks.
So stop waiting for them and go trying 3DEditor to bring them us
PS: And I should add: even if you encounter troubles and can't build your track, it's a great opportunity to report me any bug/problem to make whole track ediding process progressing. Thanks to all who had and will try.
