TMO with NSM and PE4?
 

How will I install these 3 mods together?

Have you read the readme files for each mod? Seems to me there were instructions in there about the order of mods.

Well actually there is!
I Install TM first then NSM then PE. But at stage two of PE4, you have two choices:
either install the one package for NSM or install the other one for TM. So what am I really supposed to do? I dont want to mess up with NSM as it makes the game so realistic..

Well I just installed TM and PE4 with all the files of PE for TM and over all of these i installed NSM. I hope its right...is it? :p

I don't know. Maybe someone else can shed some light here.

TMO can be loaded with PE4. But I do not remember the correct load order or fixes. See the PE4 documentation for clarification. As far as NSM goes this was pulled from TMO 1.5.2 due to many issues. I would opt of a stripped down version of NSM 3.0 for TMO. But that is just my taste. NSM 4.0 will definately not work well with TMO 1.5.2.

Happy Hunting!
