Alrighty, this is a more advanced tutorial than the one Brammer made. Let's start, shall we?
Select the
Arch tool and create a 512x512x64 brush. You'll notice it won't create a brush immediately, instead a window pops up.
Now, look at the picture below and put in the same settings (change to your likings if
1: you have done this tutorial or
2: if you already have experience doing this).
Now hit OK and, wow, a 1/4 part of a circle!
The default setting for
Number of Sides is 8, I changed it to 12 just to make it look more nice. As you can see, I already gave it that road texture from cs_747.wad. Now, open the
Texture Application tool and select the first face. Rotate a bit (read: small bit) and hit the C button under justify (C stand for Center).
Yeah, -4.00 degrees, that's what I need for the first face as you can see. Let's repeat the process... just increase (or decrease) the degrees on the next face... repeat, repeat, repeat, and on. Now let's take a look at how it would look like if we had it all done:
YES! A nice curve! But wait, what is a road without a sidewalk? Let's add that in, shall we? Select the
Arch tool again and create a 576x576x64 brush. Oh, hold on a sec, I chose that nice fitting asphalt texture for the sidewalk! Ah, here comes the popup window again.
Take a look at the next picture to see the settings I used:
Hit that OK button and you'll see another series of brushes has been created... move it around a bit and 'connect' it to our curve we made earlier ago, I also made the brushes a bit shorter, they're now 16 units high! Take a look:
OK, right side done... now let's do the other. Create a 384x384x16 brush (yes, with the
Arch tool, of course!).
Agh, that damn popup again... oh wait, we need that popup! Let's see what I did:
Yes, move the group of brushes around a bit and 'connect' it. Wayhey! That's a mighty fine curve we have there!!
Ah, goodness... let's take an even closer look:
Goody! OK, that's about it! Some sidenotes though:
- It would be best to create arches with the null texture, why? Ask the pro's, it's just good

!
- As you can see, there are quite some brushes there for just a nice curve... as you already might know, more brushes increase the r_speeds. However, this shouldn't impact the r_speeds that much.
Another sidenote: THINGS IN THIS TUTORIAL MIGHT CHANGE!

I finally know what the correct word is... a curve!
