@Feldmarshal, when you download this, you will see a folder titled "models". Copy all of the files in there and rename the copies to whichever uniform you want to replace. I attached a file with the names of the uniforms and the model names for you to reference.
@Snowman, what do you mean by "wizzle lines"? do you mean the vertical lines of the wool, or the sort of wavy, diagonal lines? The vertical lines are part of the jumper, but the diagonal lines are from the screen resolution. They appear because the textures are at a higher resolution than the game will allow, and the game does not know what to do about it, but they will disappear when you get closer or farther.
The current download does not include the green hat, so it will still be the stock color. I am going to do an updated release with a slightly better maroon beret, though.
Can you find a picture or describe the particular maroon top you want, or do you just want the same wool in red?
