1. Editing the bsp file
First of all we are going to open the pak0.pk3 file or any thirdparty map we want to edit. We can find bsp mapfiles in the
…….pk3/maps directory. Extracting the certain file is important so we can save our progress. Now we got our file to work
with, we open the XVI32 hexeditor software. We can now drag and drop the file into the hexeditor window. What we can
see now is cryptic numbers/letters on the left and the texture path on the right.
It’s important to know that a bsp file is written by the gtk radiant software and not by the hexeditor. Changing the wrong things
in the bsp file will destroy it’s structure and corrupt the map so it can’t load up anymore. A save way to change the texture path
is renaming a texture and keeping the size of the name. When i do editing, i allways change just a single letter in the texture name.
For example: In my ztn3tourney1 bsp mod i changed the texture path from “textures/gothic_trim/pitted_rust3” to
“textures/gothic_trim/pitted_rutt3”. I only changed the “s ” to “t”. But before i did that, i had to take a look in the original
pak0.pk3 texture directory “pak0.pk3/textures/gothic_trim/”. So we can be sure that the texture pitted_rutt3 is non existing.
Allways pick a name that differs from any other texture in the same directory!
