45 objects and yes your friends can see it too in multiplayer. some ppl have said that doors are too difficult to open or just they dont want so just use airbreak or something if you dont want to open them like that. but these doors will open nicely if you put them on dynamic. So here´s 5 diffrent houses also toilet and shower and it has quite good location. There´s security cameras and like security hut to add more safety :)
