I`m trying to learn how to retexture a model. As I get to the point where i have used the "Unpack sqm" tool and are supposed to rename the "mission.txt" file to "m113.p3d". The file alters its name to "m113.p3d", but it`s still a txt file type. It wont convert to p3d. How can I make it convert to p3d?! It wont open in the texture swap utility as a txt file type :-\
