Overview

All Killing Floor 2 weapon skins start from a single master material. They have a series of parameters and static switches that change the features of the material. This document serves as a reference for what weapon skin material parameter does and how to get started making Killing Floor 2 weapon skins for the Killing Floor 2 Steam Workshop.

Getting Started

The first step on creating a weapon skin for Killing Floor 2 is deciding which weapon to make a skin for. Each weapon and equipment item in the game has an initialized weapon skin material instance. They serve as an initial state for the weapon skin and it's what you'll use to get started when making a weapon skin of your choice.

You'll need to open the Killing Floor 2 SDK, open the content browser and navigate to KFGame>BrewedPC>Packages>Weapons. Select the parent weapon folder of your choice, right click on it and fully load the folder. That will load the weapon skin packages for that weapon. All of the weapon skin packages start with the prefix "WEP_SKIN" so alternatively you can use the search bar on the top and type "wep skin" and select the "material instance (constant) filter check box to get a quick view of the weapon skin init materials. Also, below is a package path for each weapon skin init material.

Starting a new Skin

In the Killing Floor 2 SDK Open the content browser
On the lower bottom half of your content browser click the "NEW" button.
A new package window will pop up
Give your package a new name by following this naming convention: WEP_<WeaponName>_<SkinName>_MAT under the Package field.
Give your new material instance(constant) a by following this naming convention: WEP_<WeaponName>_<SkinName>_MIC under the Name field
