Black Textures and other errors...
So, I am working on a map, but certain textures are appearing completely black. Why is this happening?
(Oh, another thing: I am having trouble getting an env_projected_texture to work).
does the textures by any chance have _vertex in their name? If so; replace them by the non-vertex textures.
Other than that I need more info to be able to help

Nope, no vertex textures. They are anim_wp textures.
They are fine in the editor, but appear black in-game.

Nope, no vertex textures. They are anim_wp textures.
There are at least 2 vertex textures under the anim_wip folder. Also, are you using those textures on a func_brush or a func_door that is part of a moving system like arms or such? maybe it doesn't recieve lighting when you compile (in its "closed" state)
About the env_projectedtexture: check that you set to YES the 'Enable Shadows' property, make sure that you used a 'Brightness scale' of at least 4.0 apart from increasing the 'Intensity' in the box where you choose its color (it's the fourth number, the previous three are the color)... But most important: only one of these entities is allowed to be active at a time, and you should already have one if you added your elevators, so make sure that you name your env_projectedtexture and fire an output 'TurnOn' to it when the player crosses the testchamber door
EDIT
Hmmmm.... I posted a "hammer answer" 
but I'm realizing that maybe AD_79p2 was talking about the puzzle creator, right?
useful tools and stuff here on TWP

[/spoiler]The anim_wp textures are on normal brushes, no func_brushes or func_doors.
And yes, I am asking about Hammer.
Oh, BTW, thanks for the help with the projected textures.
You know what, here is the problem.

it looks like your squarebeam models are casting shadows; disable them in the prop values 
Also make sure to do a full compile.
My guess is that you've got a prop casting shadows or something in front of it. Try disabling shadows on nearby models.
EDIT: oh wait LP said it already
