Most presets are simple files. Extract them to your Data/SKSE/Plugins/CharGen/Presets folder.
When searching for the perfect Elin race preset, it is important to check the requirements list. Most high-quality presets rely on specific mods to function correctly. At a minimum, you will usually need Racemenu and the Elin Race mod itself. However, to get the specific look intended by the creator, you might also need body replacers like UNP or CBBE, specialized skin textures like Fair Skin Complexion, and hair packs such as KS Hairdos or SG Hair. Without these dependencies, your character might look drastically different or suffer from the dreaded "brown face" bug. elin race presets
