Skin

From Jedi Knight Wiki | JKHub

A skin is a texture for character models.

Developer Ravensoft created the base skin textures for the game's playermodels. Some skins have been improved since JK2, such as some of the skins used in multiplayer.

Modding

It is possible for modders to create custom skins. Using a third party image editor such as Photoshop or GIMP, a modder can change the textures of an existing character, or create a brand new texture for a custom model. This freedom also allows for players to take advantage of the in game shaders, allowing for unique creations to be implemented into the game.
