Detail and structural brushes

Hey all!

Just a question, what is the difference between Detail brushes and Structural ones?
Ty:)

Structural is used for most main parts of buildings or any area you want to portal (All brushes will be defaulted to Structural).
Detail you want to make all other brushes that are not involved in portalling.

Only structural brushes will affect portals. As long as you dont have a Structural brush intersecting a portal textured brush you will be fine. Any of the other types, detail etc can intersect inside a portal brush with no problems.

Cfr. ZCTxCHAOSx

In addition to that, you should build your base environment using the default structural brushes, iirc detail brushes aren't solid. Every other brushset (window furniture, doorframes etc) should be detail brushes. But since you asked this (an you don't want to build superb and performant AAA maps) there is no need to use detail brushes at all, doing detailed work isn't 'the wrong way' to go.
A good thing is, when using detail/structure brushes, you can easily toggle the detail filter and blend out every detail brush at once.

Thanks bros :)

Detail brushes might make something faster, but they cause other problems like looking-through-walls with left/right leaning:

Kung how did you do that? I tried it but it doesnt work

When you look to the right (like in pic), press lean-left and be near to the doorfrome :D
