i found this last night
im making a model of my house so it helped alot with light switches
doors also teaches u to apply your own made texture with shader file
I found a prefab pack released my a clan called the lost batallion they got like 100 prefabs of buildings, items, furnature , structures, bunkers,misc download it now put stuff in your empty map lol u mappers its called prefab . zip
1} nemisis tutorals are the reasons i learned to map so detailed they rock
2} the lost batallion gives credit where credit is due all files they provide come with readme of the origonal developers they provide every prefab nemisis released and dont take credit for any of the one hundred or so prefabs
3}they say str8 out we do not take credit for any prefabs only for packaging the ones they found online themselves
