I'm looking for two mods...

One to let me smoke...
I found two on the Nexus but they are both broken. They cause my camera to go wonky and my VATS to not work.

I also want to change how the cartons look ...
but the only one on the Nexus had odd files in it and no directions on how to install it.

really the smoking mods on nexus do not work? that is a let down. i was thinking of using those for my next char (hard drinking/smoking ghoul cowboy)

This is the one I have been using and I had no real issue like you described, I would think that the camera problems are either a conflict or a load order issue.
