Module III - Appearance
Module III includes mods and full overhauls for your character and the NPCs. They focus on retexturing hair, skin, beards, scars, or even re-creating entire faces and styles. As always there are options for you to choose from. Most mods (with the exception of those that touch NPC records directly) are extremely compatible and will never require patches.
Body replacer such as CBBE are not supported (yet).
Establishing a baseline (1)
Let's start off by replacing the general textures for all things related to appearance: hair, skin, eyes, and so on. There are two major overhauls available that on their own cover pretty much everything. Some smaller mods can serve as alternatives or additions to them. I suggest taking a good look at both overhauls - WICO and Total Character Makeover - before you decide whether or not to install one of them. If neither strikes your fancy or if you're already struggling with a stable framerate, skip this section to mix-and-match smaller mods from the next step, (2), instead.
Any mods from (2) can also be installed on top of either of the large overhauls (Options A or B). They must be placed lower in your mod order to overwrite. Keep in mind that the features of many mods listed there are already included in WICO / TCM.
Adding additional appearance mods (2)
There are numerous smaller mods and texture replacers that can be used with or instead of one of the overhauls from (1). My favourites are listed on the page linked below:
Overhauling individual NPCs (3)
Besides WICO and EEO which already edit individual NPCs directly, there are some mods that go a step further beyond improving the looks to reworking them entirely. Best known is the Bijin compilation which focuses on prettying up the ladies of Skyrim by giving them new hair colours and styles, new eyes, skin textures and facial features. Most of the Bijin edits fit in fairly well especially in combination with WICO. Restoring some NPC's original look while keeping the Bijin-looks for all others is quick and easy.
Currently only the full Bijin suite is supported. More options with different NPC overhaul mods as well as a guide on how to edit Bijin to remove certain NPCs will be added in the future.
Either skip this section entirely or install all of Option A.
Unpotatofying the kids (4)
Because I'm pretty sure children don't look like this.
Two mods to rework children are supported so far, one a 'simple' retexture and the other a full overhaul in the same vein as WICO / EEO / Bijin. The latter of course requires a number of patches and integration for any new children added through mods. Fortunately, there are plenty of patches and addons for the most popular child replacer, RS Children - my favourite one which I strongly recommend.
