I think the textures themselves should be in separate files...right now I'm exporting the tex- atoms with the filename after the key "filename".
By the way, all of the textures for my zones are available at:
http://sourceforge.net/project/showf...ckage_id=34673
under "OpenZone Textures 1.4".
Edit: I made a change and re-uploaded the Veldona export (and got rid of the others)...let me know how it works out.
