Hi, i was reading the "In the Beginning" tutorials, and in part 5, it covers placing furniture, such as desks and trash cans and whatnot, in the level. The problem is that the tutorial says to switch the "Categories" drop-down menu to "Usable objects", which i cannot find. The only avalible options are "Entities", "Prefabs", and "Prefabs HL2".
I have sarched these 3 options, and the entities that the tutorial talks about are not there.
In the tutorial, the person who wrote it uses WorldCraft, which is, to my understanding, an older version (and the former name) of the Hammer Editor, so my guess is that these entities are found somewhere else.
Thanks in advance.
