Help with shaders

I was wondering if anyone could help me learn how to use shaders in torque3d. I've looked around the forums/google and it seems it's based of the material system, but I can't find anything that explains how to use it.

I tried this site, but apparently it is outdated because it had me editing a directory that didn't exist in 1.1 beta.

This thread links to these shaders,implying they can be used. Yet there is no explanation how. I would very much like to use the cell shading shader as I can't get the screen outline hack to work, and I don't like it anyway because I can't control what objects are shaded.

If anyone has a link to something I could read about learning how to do this I would be very grateful.

Cheers,
