Great job mdbobbo !
At least, we know which needs some refining....
As a new member (2 weeks old), I was surprised how bad generally speaking the tracks were made. Some have shaders, cam, physics, optimization issues which will surely last before really fixing/upgrading the best ones (best structures) for future Racer versions.
From approx. 30 tracks downloaded, only 3-5 tracks were "by default" in good quality....
Talking about those, had new ideas, to blend easily the road mesh with the terrain mesh, right ; cause this what's really makes a track, I'll try to output some bitmap (raw file formats => HM: heightmaps) from CE2, (since I've been working more deeply with this n°1 worldwide known engine) which will include a road build on top of my HM, perfectly aligned to the terrain.
Hope some of you, understands what I'm talking about....
Could ease the creation process !
