I was using another mod to do this but after starting a new game as an Orc I was not completely happy with how my character looked. Apart from a small seam on the back of the head which I am unable to get rid of, this to me looks much better so I thought I would share it. With nuska's account being closed since 2017, I am unable to get permission which I always try to get. If anyone objects to me uploading this file I will promptly remove it.

These textures need to be installed after OCO and Seamless.

Seamless - OCOv2 https://www.nexusmods.com/oblivion/mods/45859 

Brighter Orcs for OCO and Seamless https://www.nexusmods.com/oblivion/mods/51284 
The mod I was using before, compare both and see which one you prefer. Be aware my mod has face texture at 1k and body at 2k, Brighter Orcs mod is 2k for face and 4k for body.

All credit goes to nuska and junkacc11, I just turned up the exposure on a few textures.
