I think the title is obvious...
I want to start making maps...


What is a brush? Everyone says to make a brush.


Also, can someone give me a general VERY GENERAL timeline (outline of steps) on how to create a map? Most of the posts tend to be for people who are used to skinning quake 3 and 2 and other games.

It is hard to explain what a brush is, but mainly it is just a 3d structure. A wall for instance can be 1 brush. Just a large stretched cube.

A brush has only 1 thing it cannot have. A "convex" corner (i think it is called convex, don't shoot me if it is the wrong term. What I mean by that is that if you would want an L shaped brush, you would have to use 2 brushes to get the effect. Why? Because the inner side of the L cannot be done by using only 1 brush. I know my explanation kinda sucks, but I have no other way how to explain it.

A simple room. Just create six brushes, modify their height,width and lenght, and their position, so that you create a large cube in 3D. Put a player_info_start in it, and a light, compile it and voila, you finished your first map.

It's concave brushes you can't have, actually. Just fyi.
