I'm using OBMM to install and manage my mods. I've just fixed my Cobl and want to use TNR. I'm at the last part and need to install Cobl Cosmetics Rez. I will need to install two folders:

Install First
Install for Exnem --- (note: I plan to use HGEC for my own body - will this be ok?)

When I go to try to include the archive in OBMM nothing happens. I try to install the folders but cannot. I don't want to pick the files one by one (I know this is incorrect.) However, I don't just want to dump these files into my data directories and overwrite the regular Oblivion stuff (what if I don't like this or it doesn't work out for me?) I want it through OBMM so I can just turn off these textures if TNR doesn't work.

How can I get OBMM to install these folders for me in a manner which I can easily turn it off+on like a mod? Or am I missing some other obvious way of doing this other than dumping into my data directory (don't want to do unless I'm sure meshes and textures won't overwrite the vanilla stuff).

Did you check the cobl races thread there is a updated omod script just for Cosmetics File once again.

You want to use Cobl Race TNR that will only change face, hair, eyes.

Post in Cobl Races thread and I will help you further there..
