I'm creating a set of train tracks for a game known as "Garry's Mod". It runs on Valve's Source Engine, and for being an old game engine, it has it's quirks.
Namely, the inability to create smooth curves from within the engine's map editor, "Hammer World Editor".
I can create curves using the editor's built-in arch feature, but the curves aren't smooth, since they are just a bunch of straight blocks put together.
While I can increase the amount of pieces on a curve to make it look smoother, for some reason the editor deforms some of those pieces and makes the tracks look bad.
A friend recommended me to take the "blocky" curve, so to speak, and run it through Blender, to smooth it out. But that's where my problem resides.
How can I do that? I already have the prop loaded in Blender, but I'm a complete novice to it.
