Hi DarkCore,
X is the only supported mesh format at the moment. To export the heightfield as X:
- Select the heightfield (view->show map->heightfield).
- Open the export wizard (file->export->active map).
- Select 'X (DirectX)' from the format drop-down list.
- Set the filename and click OK.
Note that the output is in ASCII mode, so it's probably going to be
a bit big. If size is a serious issue, you might want to look into exporting the heightfield as a TER or BT file, then use a TER/BT->3DS utility to convert to a binary mesh. I can't name one of the top of my head, but either someone in the users' community will, or else you might want to Google the subject.
Cheers,
Aaron.
