3D Skyboxes
From HalfLife 2 Knowledge Base
This is quite surprisingly simple to do. Here is how to make a 3d skybox to add a more realistic environment to your map.
- 1. Place a sky_camera (entity) at 0,0 for reference purposes
- 2. After your map is complete and you've setup your 3d background brushes/entities (aslong as they aren't player spawn/npc/monsters) and don't forget your Light_environment select them and the sky_camera (make sure you also grab your Light_environment as the one in your map wont light up the 3d skybox.
- 3. Copy and Paste and then (you don't have too but I always do to be safe and this way your Light_environment isn't lost either) go to tools/transform then select scale then set x,y, and z to 0.0625 (1/16th the size).
- 4. Move selected out of the way of your map (a bit outside) and then close up your mini background with a skybox (completely surrounded like a cube).
- 5. If you copy & pasted remember to remove the larger version of your skybox (the brushes you created) and also the extra sky_camera in your map (not the one in the skybox)
- Note: You can apply the nodraw texture to sides of the images you won't see when in game.
Simple as that. It's best to do this after you've finished your map (but give it a try before you start on one to get familiar with it)
