Step 1: Go to Any Site Where the Skins Are Available for Download.
Step 2: Now That You Have It Downloaded...
Mine is "C:\Program Files (x86)\Steam\steamapps\rain_of_flaming_deth\Left4Dead\left4dead"
Now, copy the material file over. You want to merge it with the existing.
Step 3: Edit the Whitelist.cfg File
Note: this only needs done one time, so you do not need to repeat it for every skin.
Step 4: Now, Find the File Name of the New Skins.
Step 5: Edit the Pak01_dir File, Using Notepad++
Find the " $baseTexture "models\infected\hulk/Hulk_01" " line. Simply change it to " $baseTexture "models\infected\hulk/Hulk_02" ". I already have this done.
For other skins, you will need to find its respective line. Also, if the file you downloaded contains more than one new skin element, you will need to make the other changes too.
Step 6: Lets Try Another.
This file has two lines that need changed.
This witch is just a little bit better :)
Step 7: Edit the BaseTexture Line
then the next, for her hair.
$baseTexture "models\infected\witch/witch_hair" to $baseTexture "models\infected\witch/bitch_hair"
Step 8: Close All and Play L4D.
Step 9: Closing Notes.
Also, can you help correct my grammatical errors if you find any? Or give me a suggestion as how to better this? kthxbai
