Need Help putting Gerd's HD warmups in my game

i tried using the 2k mod tool after watching Lunatic Wolf's tutorial, but when i downloaded the mod tool and gerd's jersey textures they were regular .iff files for the warmups. I need some help as to how to put them in. Im lost.

the iff files are because the warmup texture is bundled in with the normal jersey texture, so all you have to do is pop it into the game for it to work

if you want to add the warmups without replacing your current jerseys you need to open each iff file up with the mod tool, export the warmup texture, and then open up your current file and import that texture in manually

The Mod tool wont let me open up the jersey iff file. When I browse to try and find them the program only looks for dds files and i cant change it.

whut? you open the program, click open, open Gerd's warmup uniform.

find the warmup texture, export res, save it

close gerd's uniform, open the uniform you want the texture in, find the warmup texture, import res, select the dds you just exported, done.
