I have made a series of videos that explain the world editor tools and how to use them
These videos are made with New Players in mind so some of the information is pretty basic if you already build in 3DX, however there is some tips and tricks in them you might find useful!!
Please enjoy and let me know if i have made any bloopers!!!
Video 1, is about the basics of the file menu, saving and loading files.
Video 2, talks about the Save Selected to File
