Hi, I'm a guy from Sweden who's currently going to game development college. I'm interested in game development, creating 3d models and programming.
Learn the basics of optimization, learn about leafs and portals and how to keep their numbers down using func_detail to increase compilation speed.

First there's a quick theoretical walkthrough of how leafs and portals work. Then the problem is presented; round shapes and details.
Then we open up hammer and create a cylinder, we compile the map and see a large amount of leafs and portals in the compiler window. Then we tie the cylinder to the func_detail entity and compile the map again to see that the number of portals and leafs have decreased a lot.
