Any guides or tutorials for creating a ground mesh in 3dsMax?

[cherub]

I'm having a bit of a problem with trying to make a ground mesh in 3dsMax for importing into Openzone. I either get an access violation, or my non flat plane in Max shows up as flat on import. I know my way around Max decently, but I'm hoping someone could give me a quick guide on making something that will be able to be read by Openzone. The more specific the setup in 3dsMax, the better as the only thing I can seem to get to import into Openzone is a small flat plane.

I guess all I want to create is a hilly ground mesh with a gradiant color scheme for the highs and lows if that's possible. Thanks in advance.
