Hammer limit ,question.

I have read that you can only put 4096 brushes on your map. what counts as a brush dose a cube count as 6, 1 for each face, or just as 1. same for the props. and dose a brush with no draw still count as one even if its not rendered?

MAX_MAP_BRUSHES
Maximum: 8192 brushes Description:
primitives or brushes, e.g. boxes, cylinders, spikes. Triggers and nodraw-brushes are also counted!

Solution:
Be sure to check your level and see where you can remove or merge brushes. For some things (especially small things) it may be better to replace them by props, or bumpmapped textures.

Brush ##: nummapbrushes == MAX_MAP_BRUSHES Side # Texture: [some_texture]
Description:
You have too many brushes in your map (more than 8192) The given brush is just the first one to go over the limit, it's properties in this error are useless

Solution:
Delete some brushes, turn some of them into models for area's high in detail. For singleplayer maps, you may decide to add a level transition and split the map into multiple levels. Multiplayer maps that reach this limit are probably too big for multiplayer anyway.

There are many limits you can hit but to awnser your question in this case the brush itself is counted as one, not the individual faces.
