Pick up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa. And a lot of people, people he cares about, are counting on him.
This is a tutorial explaining the basic way of creating 3D Skyboxes in Hammer.

Hey guys! and welcome to my first tutorial! In this tutorial you will be tought how to create 3D Skyboxes in Half-Life 2's level editing utility. Hammer! Also, I will not go into how to make a room, simply tell you what I did and what textures I used. Then show a screenshot for you to follow along, as it is easier.
I have already created a room that I will be using, it's a really REALLY basic outdoor map, and is only used to show an example. So the first thing you will need is a box room. Next, make sure that the walls and ceiling of the room have the "tools/toolsskybox" texture. This room is 512x512x512, and just has some basic walls going around the parameter.
Alright! We have a room! :D Now we need to work on another room, to make this easy, you can select all the brushes and shift drag it to a different location. Now that we have two rooms, we need to delete the walls in our second room, and make sure that all the walls have a "tools/toolsskybox" texture.
On the left is the perspective view of the second room, on the right is the top view of both rooms.
Right! This is were it get's a little tricky. First, you need to have a light_environment entity pointing in the exact same direction, in both rooms. This helps with keeping the lighting correct. In the center of the second room you will need a sky_camera entity, place this low to the ground but in the center of the room. And then finally, you just need to lob some skybox models AROUND the sky_camera.
Hopefully, all the walls that you placed the "tools/toolsskybox" on in the first room, will be replaced by huge towers. :) Giving you your 3D Skybox :D
