I already have some decent animated race horses, starting gate and some nice scenery models (stadium, etc.) I created in Blender.
I am planning on putting a lake in the middle of the race track with a bridge. My ground landscape is going to be a huge plane with a grass texture and I stumbled upon MikeMax's Terrain Height-map generator:

This a very awesome little utility which will take care of a nice grass mesh and the lake.
Now I'm just wondering whats the best way to place the oval track of dirt simulating the actual race track. Would the best approach be to model the track and place it slightly over the grass terrain generated above or to paint it on to my map texture? After that I have to create my fence (railing) around both sides of the track which I already modeled some good looking pieces.
And much thanks to MikeMax as that height-map example is truly amazing!
