That tutorial is good, but it's time consuming and the textures never come out seamless. You can even see it in the pictures in the tutorial. The road lines never line up properly.
I mentioned Dispgen before, but I totally forgot about the much newer and better Twister tool (download here
). You can put in Hammer unit measurements and generate a perfect curve via displacements. You can choose the displacement power too (2, 3, or 4) for a higher resolution mesh. Textures applied to the curve are perfectly seamless and can be stretched how you wish. Observe this picture:
You can use the clipping tool to make the displacement mesh even more detailed (and it can also be used to control how the texture fits on the displacement). You can even make the curve sloped via vertex manipulation, and it's much
easier and faster than manipulating the vertexes on a triangulated arch primitive. It's just...better in my opinion.
It would be somewhat tedious to integrate it in to your map properly, but Twister can also generate edges for your curves so you don't have to manually create them via brushes.
