Hammer Tutorial #21 optimization Part 2- Solving Leaks, Fish bowl theory

In this set of 5 tutorial you will learn optimization 101. Optimization is making your map run better, and result in better game play. When done correctly you will also learn how to majorly cut down on compile times.

Common terms you may not know but will encounter:

World brush: a brush that isn't tied to any entity

Skybox: the collection of "tools/skybox" textured brushes that cover the top of your map, giving the appearance of a sky

3d-skybox: see above, only instead of an appearing sky projects another part of the map

Framerate, or FPS (frames per second): how fast your map runs, the higher the smoother, the better!

Compiling: To turn an editable map into a playable map

vbsp: The first compiling program, takes care of general BSP structure, and portalling

vvis: The second compiling program, takes care of visibility, can take hours on an unoptimised map, luckily can also take seconds if optimised right

vrad: The third and last compiling program, takes care of ( the static ) lighting your map

bsp: Binary space partitioning, basically a format to write and use maps (originally ported from Quake)

Console commands:
Sv_cheats 1
Mat_leafvis 1
Mat_wireframe 3
