This is something which I whipped up several years ago for a mod which went unfinished due to a hard drive crash. I recently found the texture on an old flashdrive, so here you go! :)
I've given both textures the file names as Korriban's textures, so if you want to use it for your mod, you'll have to rename them. There are two folders which you'll find in the zip file, K1 and TSL. This is because the two games have different naming conventions, not because of any issues with porting. To install, take the files from either of the two folders and dump them in the respective game's override folders.
