Any brush that doesn't seal off the hull of a map from the void can be made detail. That tends to mean brushes used as decoration in a map. It helps speed up the vis process because only the major parts of the structure of the map are considered.

@ fKd, like Anwulf said, when a complex map compiles, if the compiler had to consider every little bit of trim and crack in the floor and tiny light sticking out and stuff like that, then the compile would take forever, and your map wouldn't run as efficiently.

The detail flag is kind of a way of saying to the compiler "pretend this brush isn't there" for some purposes (like visibility calculations). Basically, all major walls, floors, etc. should be structural, and all the fussy stuff should be detail (and don't forget to use the caulk texture on hidden faces of detail brushes).

detail brushes won't cast a shadow so use detail wisely

i'll post some screens soon... btw... its not the vis that is so bad... its the lighting... anyway to make this render faster? im using q3build..

Yeah I know, but come on, if he'd use the search function or checked the stickys, he could have gotten this question answered and saved you for some time.

For Q4 perhaps (not sure about this)??

Not true for Q3.


See the sticky threads. There have already been resources and tutorials written on the subject and will go into far more detail (heh... no pun intended) than we can be bothered to post here.

detail brushes cast shadows in Q3. detailing is a VIS optimization feature, and has no effect on lightmaps

speaking of detail brushes, a future build of radiant could colour code detail brushes in the 2D so they stand out more. this was built into CoDRadiant, and is invaluable in hammer

Yeah, I know, but a simple "Search is your friend." or whatever would be better. Worst case, he could have taken you seriously and wandered off to compile-time hell, lost all hope in life or joy or God at about hour 400, lost his job from heavy drinking, and ended up selling his ass in a dirty Vegas backalley to support his crack addiction for the remainder of his tragic life.

All because u leid!!! :tear:

Better to start a new thread for this, 'cos it's buried in the mass of incidental posting in this one.

Yeah... was wondering WTH ;)...

From what I have seen mapping for Q4, detail brushes actually *do NOT exist* at all. You can try to turn a brush into detail, and then via Ctrl+D check if Q4's editor actually hides something. It does not, so lighting can't be effected by turning a brush detail.

It may be possible to set certain flags for brushes, e.g. that they do not cast shadows. Though I have not seen that sofar.

ow .. thanks guys for not hammering me on my error, i have mapped for years thinking details cast no shadow.

We're a bunch of level editing nerds with nothing else better to do.

Welcome to Quake3World, BTW. :p
