whatsup Torque 3D users!
I worked in a few old demos levels lately, to rescued, clean up, hunt missing scripts, arts, files and fix a bunch of bugs.
Even I fixed bugs, hunt missing stuff or re-arrange the folders or paths and tested to work with the latest version of Torque3D, this levels is not look like the author want it because a lot of changes in the engine, shadows, shaders, lighting, parallax, fogs and colors, but it is the closest 
The best I think, you do not need to worry about to use other project for test this levels, just throw inside your folder (read the instructions) and copy the level file. This will not mess with your stuff, when you finish, just delete the level file and the demo folder.
All the art can be used in games, just read the license.
