How do you make those smooth roads like that?
I just wanted to know how do you make those smooh roads with displacements, I tried everything, I tried by making an arch and editing the vertex but it doesn't render in game because apparently you need to triangulate, so I did that but the result is meeeeh... There are bumps in the roads. For a road that just goes down I tried making it with a slopped brush then making it out of displacements and then subdivide it but there are still a lot of bumps, I tried smoothing with paint geometry, result: If I didn't smooh enough the bumps were just larger, if I smoothed too much, it would just give me a straight plane, not slopped. I even got to the point of decompiling your map, breaking the displacement to see how you placed the brush to make it, but when I remade them to displacements I tried subdividing but it didn't give the same result, so I thought you made them manually but no, that's literally impossible, just inhuman because the curves are so perfectly round. So I thought maybe you used a program like Twister, but no because all of the displacements that you make with this program are ♥♥♥♥♥♥ with their box around, making them impossible to place and also because it would have been a pain in the ass to make those other displacements beside thd road, the ones covered with grass texture, which are perfectly align to the road.

So yeah that''s why I'm just asking you directly, you seem to have found a way to make it, yet people like TopHatWaffle and WorldOfLevelDesign just made videos about how to make roads with SOLID BRUSHES. Nobody on the internet was able to explain how you did it.

I learned this from an old FacePunch thread that's now gone. Here's how it works:

Step 1: You make a rough version of the bend out of big segments. Personally I like to do it with 7 big segments in angles of 30 degrees, but it can be done with as few as 3 segments on really tight bends

Step 2: Make another equally wide bend on the outside, then one equally wide bend on the inside. BOTH MUST BE EXACTLY AS WIDE AS THE MIDDLE SEGMENT! This is important.

Step 3: Make the brush tops displacement, choose all the middle, outer and inner displacements at once, then subdivide. Boom, smooth curve!

Bonus: For an angled bend, make the outer subdivision help brushes as tall as the road is wide, then do the displacement on the wall instead of the top. Once you choose everything and subdivide, the bend will be banked instead of flat.

It works! Thank you so much!

so I searched in the facepunch archives and found this https://web.archive.org/web/20181012180643/https://forum.facepunch.com/f/mapping/rowp/Smooth-curved-and-sloped-roads-using-displacements/1/

which leads me to this https://imgur.com/a/FDFNk

a better explanation with images if anyone else is interested.
