I have tried going into the sun entify info and made ssi night a that does not work still

So i got day skybox and i want my map to be night, i have gone into light states and set up night for radiant but i dont know how to make it night in radiant. a little help please
Thank you

So i see that many people have added weapons onto workshop for bo3 but is it possible to get them in the mod tools so i can add them to my map?? any ideas

Ok so first off i looked everywhere for this but i cant find an answer so this is what i have i got a door with
script_flag "enter_zone2"

i also have the start_zone and zone2 set up like every video i have looked at and when i access the gsc file to configure i put this down in the right location
function usermap_test_zone_init()
{
   zm_zonemgr::add_adjacent_zone( "start_zone",      "zone2",      "enter_zone2" );

}   

what am i missing i run the game and can open the door but i keep dying while walking in!?? any solutions also this first time making map so give me a little slack
