After finally deciding to reinstall Oblivion and all its mods, I started the game, and, after Renault's apparent aneurysm, her body turned green. I can post a mod list if it's necessary.

You're missing the blood textures from MMM, so doublecheck the install. If using the MMM 37b3 version, which you should, make sure you have the MMM.bsa and that it's renamed to Mart's Monster Mod.bsa.

I did have a file called "MMM.esp," but it was just an ESP and it was like 1 kilobyte or something.

Edit: Never mind, I read your post wrong.

That was actually added by the OMOD script in order to load the BSA and save you from this problem (or having to worry about renaming the BSA). If you deleted it, that's why the problem started for you.
