With the Source engine, I want to make a map in the outdoors (similar to something like Dust2 or Inferno) but not let in leaks due to the open top part of the map. Is there a way I can do it without the leaks?

1\$\begingroup\$ Having used Source, I can say with utmost certainty that the engine doesn't support that kind of environment. Every level needs to be contained in a box, be it a Skybox or what have you. It's just the way the engine operates. Granted, you could just have one massive skybox. \$\endgroup\$– KrythicCommented Dec 3, 2016 at 18:58

\$\begingroup\$ @Krythic If you want to post an answer, post one. Posting a comment and getting upset when people post an answer with similar ideas isn't reasonable. Post your answer and the community can decide by votes which is best for this question. \$\endgroup\$– HouseCommented Dec 4, 2016 at 20:44

This is done with a skybox. In reality, the maps are still closed; they are simply using a special material which marks the space as to render the skybox, which is what ends up looking like the sky. Therefore, you must enclose the level with the "tools/toolsskybox" texture, while leaving sufficient space for things like grenade throws to happen. There are multiple versions of skyboxes, I suggest you read through the VDC article here.
