You all know those orifices or holes, you see when you go past a window inside a building ( take turnpike for example ) I´m talking about how a brush is pushed inside/cut out, so that you can fit a window in there.


The alternative that ive been using is just making 4 brushes ( one on top, below, right and left ) so that a square in between the wall forms.


Of course this
takes more time than actually using the right way


However i do not know how its done. I look at the windows inside Turnpike´s main buildings for example, and see no marks around them, indicating that theres only one brush as a wall, and somehow he clipped an area inside it to form a square.

Where he put a window texture on another smaller brush.

How does he do this? I know the clipping tool well, but i cant figure out how to achieve the same result.



The same exact thing happens when i want to create a staircase leading down into a brush, but i want to maintain the inner walls of course. I cant make a brush and just cut a rectangle inside it :/

How do they do it?

This is correct. Brushes MUST be convex, which means they cannot have holes in or be L-shaped.

Not really sure what you mean but if you want to cut a shape into a wall you can just place the block shape in the wall and use the subtract(?) tool? (ctrl+U - ?? Cant remember)
This will usually split the wall into 3 bits but it is all seem-less leaving the exact size block cut out of your solid surface.

How should i do it then? Im making 3 main office buildings, and several windows on each side. Making 4 brushes on each sides of each buildings takes forever xD


Is there any other way?

If you are making rows of windows then you probably only need one brush above and one below all the window, then make the brushes to the sides individually.

Mapping does take forever; get used to it. :)

NulL is right. The other way that xlr8r mentions is using CSG subtract and it creates a lot of extra brushes. This was used on Casa and causes problems over time with little cracks forming around the doorways. I have to constantly rebuild them using NulL's much cleaner method.

I've recompiled ut4_uptown (4.1 version), and brushwork is there very "dirty" too :P
