When I first saw the track editor announced I was really excited about it but looking at this its a big let down.
Don't get me wrong, its adequate and suited to allowing anyone regardless of any "artistic" or technical ability to create a custom track.
Ideally I'd have liked this system as a "wizard" like track editor for those who can't and a more involved track editor for those of us who can. I'm a CG artist (in a professional capacity) so the idea of a track creator really, really appeals.
I know it's not going to happen but I'd want a fully fledged editor where I can create the terrain for the "area" using a system a bit like the terrain editor in game engines like Unity3D, BigWorldTech and the likes.
An asset library where you can drag, drop and place any 3D models used in the game.
A tool that allows you to "draw" the track. When I heard of the track editor I assumed the track would be created a bit like a vector spline at the very least; so you'd draw the track, corners and flow it over your landscape.
Or even better do something like games created with Unreal Engine do, package the editor (just the track editor they actually use) and allow the artistic amongst us to go wild and share it with everyone.
However it was approached (either an editor that requires some level of skill but is accessible or packaging the actual track editor), you could basically create any track you liked and then share it. Even better maybe a 3DS Max/Maya plugin to export your own artwork that can be plugged into the asset library.
Now I know you could argue that a lot of people couldn't use it; which I'd argue against to be fair, anyone could create *a track* but maybe not a good one.
But what it would enable would be that those of us who are capable could create beautiful tracks to share, those who aren't artistically capable could create tracks for their own use or download the shared tracks from those who can.
