Diehard has released major updates in the last week to the st3c textures packages ( as far as i can tell) including alot of fixes , how you can break a texture i dont know hehe.
But he has neatly posted then on this oldunreal page , in a easy to figure out not burried 400 levels deep format ,
They are huge files , and you should go there and see what you need first. Before you download them , These textures only work with certin custom renderers ( opengl dx9+) and in 227. so if you have vannila 226 , you may want to skip them.
i personaly wouldnt recommend extremeend version as its just hugy huge (2 gb files) , But most pc’s less then 5 years old should be able to run the high end ones.
they do massivly improve the looks of unreal tho , but after you get used to them and then then play without them you will realiz just how crappy the original unreal texturees looked compared lol
edit: where are the checksums for all the files.. md5 etc ? there big files….
