It's possible to make flat brushes in Hammer, my question is though, is there any use in this? Does it increase performance even a tiny bit if I used it for surfaces where only one side is showing anyway (I doubt it). And even if there isn't any benefit are there any problems created by using them, because I'd like to use them to just stay tidy in some areas.
Flat brushes in Hammer

I assume you mean one side, but can you delete sides without creating a displacement? And if you have a displacement you'll have sealing problems if you just treat it like a normal brush. For every flat face you'd have to have a whole nother nodraw brush for sealing.
Unless you can make a one sided brush without it being a displacement, which I've never heard of.
-
I guess you could apply nodraw on the other faces, and use a texture with "$nocull" 1
-
Planes and the like are not possible in Hammer. Visually, a displacement will be the closest you can get. That, or a one unit thick brush with nodraw on the sides.
-
Hmm, I could swear I made one before. I must of not been paying close attention though or I must of been dreaming. And yes I have dreamt about mapping before
-
Well to be perfectly clear, they are feasible in Hammer, but if you end up with one, you screwed up somewhere cause it's bound to cause an error in your compile.
To create one, you can make a simple brush and weld the vertices together. The brush will still exist according to Hammer....
-
The closest you can get to a 1-sided face is a brush with the null/nodraw texture on all sides except the front and then merge the back vertices to make it form a pyramid.

No I mean a regular rectangular brush that's been flattened to create a 2-sided brush.
hammer can display that but its not working with the engine. you m ight eliminate those faces with a nodraw material on it. then the compiler will drop those polygons -> speed up
-
Oh I do that anyway. I was just wondering so I could be orderly with it. I hate taking brushes out of position to check if all the unnecessary sides have nodraw on them
-
you dont have to place it on all unseen sides if you work proper because the compiler eliminates faces that are either outside the world or that are aligned to another brush without a gap. (like old csg compiler did)

Oh
Thanks for telling me, this will save me some time in the future
