    Gentlemen.

    I would like some advice on how to make a curved slope, or rather a road which is both arched around a corner and going downwards at the same time. Like a spiral, I guess, or something akin to the big car tunnel in Hydro.

    I've been trying this for a couple of hours now, with no hint of success so far. I have got a feeling it has something to do with displacements, but I just can't figure it out.

    Tried searching, but nothing related came up.

    At this point, any help at all would be appreciated.

    There are 2 ways.
    Make a curve out of brushes, cut them up into triangles and vertex edit them into a slope.
    Make a displacement.

    I would suggest the latter method.

    Haha, another spiral request...
    Displacements are the way to go. There are a number of programs on the internet that make 'em for you, but none of them come up with results that can be sewn together. If this doesn't matter though, try this or this.

    I'd ask Iika Keranen or give up.

    Or if you want to cheat, copy/paste the one from hydro, and modify it to your uses.

    I'm trying to think of some ways to do this simply. You can math it with some displacements, a calculator, and a function for the curvature, but I don't know what you would want.

    Fubar, that tutorial is amazing. I remember when it came up on interlopers, but WOW :O

    And I used twister for my needs, just remember to seal off the displacement with nodraw.

    The displacement method is basically to do what the tutorial Fubar posted says to do, but then create a straight block brush, convert the top face to a displacement, and use Paint Geometry to twist it into the shape of the slope you already made. The tricky part there is getting the inner vertices to line up correctly. This might require making multiple slopes inside one another.

    Good luck.
