Installation TLDR:
-Completely remove OCOv1 if you still have it
-Use NMM
-Seriously use NMM
-Install body replacers, OBSE and Blockhead first
-Then v2 core
-Then v2 body replacer patches
-For the love of God use NMM or OBMM for installing, don't do it manually, I've warned you
Before you install:
- Make sure you have your body replacers in place BEFORE you install OCO. OCO needs to overwrite their components.
- If you've previously used OCO version 1, remove it completely and delete the ESP and all of its folders.
- Take your time to read through each installation step to know what you're putting where. This is a simple out-of-the-box mod if you run it practically standalone without other mods, but things can get conflicted pretty easily.
- Things you CANNOT run together with OCO:
-Hair/eye packs that affect vanilla races
-Any mods that affect vanilla NPCs
-Mods that change racial stats
- OCO comes with its own body textures for each supported replacer and vanilla. They're tailored for the mod, and using any other texture replacers on top will result in more prominent model seams and possible colour disparities.
- OCOv2 only works with an English language copy of Oblivion as it alters race records and NPCs. Users with other languages will get mute NPCs. It can be patched for other languages, but I'm unable to do that for anyone. Feel free to make your own and I'll gladly link to it from here.
- All NPCs and player characters in the game are affected by the changes. Any mod that uses vanilla races for additional NPCs or races will also take after OCOv2 modifications. They can have varying results as OCO heads generally need to be custom made to work best with the mod.
- OCO comes in one big package encompassing all the changes. It's not possible to split into more customizable pieces while keeping the broader visual integrity as many parts are interdependent. Currently the whole mod comes as-is. It's intended to be run by itself without many other cosmetic mods as it does in one go what has usually been done with a large number of different mods.
- For best results, run OCO with a nice ENB config with subsurface scattering, skin shaders and colour correction enabled. The one I'm using in my screenshots is the Midhrastic Fallout ENB, as those generally work seamlessly with Oblivion too.
