Need some help with 2K texture pack (nebula)

i just downloaded landscape and towns version of these mods from nexus using NMM, i am new at this, so please bear with me, in NMM under mods both are listed as activated, under plug-ins tab the official Beth Texture packs 1,2 are checked, when i load the game i dont see much of a difference, am i suppose to disable the Beth pack in order for 2K packs to work ?

i dont know how to use console commands either, when i load the game, the game start up only shows the 4 mods i got from steam workshop as syncd, not the ones i got from nexus, suggestions ?
