Credits to Meaaov for creating this tool UFO Edit 1.4 version... It is used for editing/importing models to UFO trilogy games :D
Meaaovs UFO Edit is a tool for editing models but cannot change the geometry but edit some other properties and it is currently in version 1.4 !
As you read it you can import OBJ files and saving Aftermath compatible models and so game will/probavly run it and for Aftershock and Afterlight will not because the tool is still in beta and I dont know when it was made and when was the last update so people that know programming... Please help the UFO community to make mods! Thank you!
