Yes. Just choose "Unpack all" when doing to BSA unpacking with OBMM. When uppacking the Oblivion - Meshes.bsa file you should end up with 3 folders...
Meshes
Trees
Distant LOD
Just right click on the meshes folder and choose "Optimize with PyFFi"
Or
you could unpack the Oblivion - Meshes.bsa to the "In" folder within the PyFFi installation location. Once unpacked there, you would need to right click on the Oblivion_optimise.ini file to run the "Optimise with PyFFi" option on the files you placed within the "in" folder.
Either way should work according to the latest PyFFI update.

Okie dokie that's what I did. It's still doing it in a command promt. So then afterwards I use OBMM's BSA creator to make a BSA with the Optimized meshes, name it "Oblivion - Meshes", then replace the one that's being used in my Data folder?
Sorry for the constant questions, I haven't been able to find an instructions page anywhere. :shrug:
