I made a macroblock pack of Nadeo bases for the Canyon, Valley and Lagoon environments.

What does this pack include?
-Trackmania Turbo bases from all environments, from normal map editor
-Trackmania 2 Campaign maps bases from all environments, but all segments are removed
-Trackmania 2 Easy map editor bases

I created it by boredom, maybe you can combine something with them. Here's the direct download link:
