I've installed the newest Nexuiz and what i saw? Ugly cartoon-like shotgun and ugly item models. How can i change it to old ones?

get an old version of nexuiz, and open the two PK3s with 7zip or something. Then just delete the /models/ directory on the new version's pk3, then drag the /models/ folder from the old pk3 to the new pk3. Or, get the old models folder from the old PK3, and put it in a new PK3 called 'oldmodels.pk3' and that way you can just delete the PK3 if you decide to switch back.

BTW I'm referring to the 'data20070123.pk3' or whatever it is...

hm. the link in the post you refer to doesn't work anymore. any chance to have someone else upload the old*.pk3's ?

Maybe you esteel ?
