Some good news for those of you who are not ardent 3DSMAX supporters. A group that contributes to OpenNeL has a proof-of-concept Maya plugin and exporter that they are beginning to test. It supports exporting most everything OpenNeL requires with the exception of some skeleton and animation related bits of data. They're also writing a patch painter that will harness innovative Maya features to allow the rapid creation of landscape zones.
