Here is a futuristic racing track concept that I have been working on recently.
Download the blend files here :
Hyper_Racing_Track.zip
I have packed with the download all the necessary blend files to render the arrow and panel textures that where used, just open the files and press the animation button to render the textures.
I will come back to this later on, for the moment I have a lot to do, anyway I hope this will help some of you to make some awesome racing tracks.
