Right now, every compiled wmb Level includes
all used textures right into the file, - creating
huge level files.
It would be much better to optinally reference the
textures to an external WAD (or Folder) and loading
them out of the WAD at level load, instead of packing it
into the levelfile.
In a (normal) scenario where a game uses many wmb files
based on the same WADs, the published game assets get much bigger than needed.
Also loading textures externally makes it possible to
alter textures for all levels, without the need to
recompile each level.
