This guide will aim to list all of the mods that make NPCs look different. There are over a dozen mods that do this and I'll be re-uploading the ones I have since some are hard to find. I'd like to make a guide on how to make them look the best but I definitely don't know how to do that.
Make sure to check out this LL thread for some nice info.
Large overhauls(Typically conflict heavily)
- Oblivion Character Overhaul - Different version from the below. It's possibly friendlier with other NPC revamping mods.
- Oblivion Character Overhaul 2 - Updated OCO with support for the Blockhead OBSE mod. Very popular NPC overhaul mod but I think it looks awful.
- Tamriel NPCs Revamped - TNR was always unpopular amongst anon since it makes certain NPCs look worse than vanilla.
- Cyrodiil NPCs Remodeling Project - This was made with TNR in mind so if you're using a bashed patch it will only import the NPC inventories if there's another mod already changing the faces of the NPCs. It seems half decent and half really bad.
- Waalx Animals and Creatures - I talk about this in my modding guide.
- XeoSP++ Rebuild with PlomsOrcs & CCC - CCC adds almost every hair and eyes to an .esp and XeoSP++ turns NPCs into animes.
- Oblivion Character Replacer - Ploms made a character replacer and says it's really bad and that I shouldn't include it here.
Smaller overhauls(Typically mergeable with bashed patch or with minimal conflicts)
- Younger Hotter NPCs Women - Does what it says.
- Younger NPCs - Sets the age slider to youngest for all the races.
- Better Looking Female NPCs - I think this was my preferred NPC enhancing mod back in the day.
- Cute Orc Head Replacer - Replaces Orsimer head meshes and the .esp changes 5 NPCs.
- Osimer Overhaul & OCO2 patch- Makes Orcs look meaner.
- Better Looking Races series - These mods are decent.
- Yams Improved Redguards - Yamsy uploaded this for me for some reason. I don't think it was finished.
- Better Redguards - Another Redguard fixing mod.
Japanese mods I've never tried.
- I uploaded all the ones I have(organized) here - I've got probably every file from SHY but most of them aren't sorted, these are mods I probably found on SHY 2.0 or elsewhere.
