And who might volunteer?
Of course, I'm not saying that someone must do it, nor that it's the good way to do it, just saying that it is possible
You have tested this?
Of course !
Here some screenshots :
Current tex :

New tex from my tutorial (512x512):

And yes, it should work with tex that have been scaled and shifted. I haven't the source map of Durango, but I guess this clothline are scaled and shifted.
Current tex (200x200) :

Just the same at 256x256 (I have added a "256x256" mark on the tex for the proof, but too bad the textures is used reversed as you can see :S ) :

If you wanna test it by yourself, just download this :
http://pagesperso-orange.fr/dans.la.rue ... une_up.pk3Place it on the right directory and start br_durango, you will see
(as long as you don't recompile the map).
That works because Q3engine normalize all texture size to 1.
It looks like we are going a little off-topic, if someone could split this thread...
