Build Flat File Information
This takes all existing FLAT files previously read and combines them into one PWAD. If any FLATs were replaced by an external PWAD, those are used instead of the main IWAD values.
Here are two examples of why you would do this:
1. Use this to make a file with all FLATs to convert from one game to another.
2. Use this file for all FLAT drawing! All the Flats are present at once for you to experiment with.
See Graphics - FLATS for more information.
Note: It takes a bit to load the this Flat file, so be patient when it is loading.
