Pretty neat Vietnam map came out a while ago by Mondkalb: http://www.armaholic.com/page.php?id=12402
Also a few honorable mentions, but they are more South American than Vietnam:

Unsung has a few new maps as well.

I tried getting some ARMA maps to work with a converter, but most of the jungle ones have parts that don't quite convert over, so the maps have anomalies =\.

Which ArmA terrains are you talking about?

What problems did you encounter?

I remember trying this one out. It was very dense and the vegetation models (the ones that worked) were very nice.

I'm sure it looked great in Arma, but in Arma 2, some textures turned white, and points of the model would shoot off into the distance and warp

Models turning white means textures are missing. This most likely is wrong path in your model.
