Make a car drive along a track

We have been given a road course track that the client needs a car to drive on. It’s simply a basic car follow on path, not actual simulation. I have found that drawing a spline to follow this crazy course is NOT going to work because there are crazy elevation changes. I can’t possibly draw a spline in Ue4 to follow this road. We can project a curve in c4d or max or maya to follow the road course, but amazingly in 2020, you STILL don’t seem to be able to bring a spline in. Is there a way yet? Last I saw in 2018 was no, but that’s all I’ve seen on it. anybody have any updated information?

Otherwise is there a way to designate certain polygons as the “road” and have an object follow the topology at all?

All I see are related to using splines generated within Ue4 which like I said won’t work.

Noon’s video would work except there have been deprecated nodes and Noon’s probably been killed over it. Any updates on this?

Why wouldn’t it work? You have full control over the tangents and rotation. You can do the sharpest twisted 180 if you want. While splines sure have their limitations, this does not sound like one of them.

I don’t get it. So you both can and cannot use a spline? Or is there something about UE4’s splines that you cannot make work. Would you share the actual issue? Perhaps there’s an easy fix.

If you can be bothered, could you produce an example where it does not work the way you envisioned it. Besides that. Automatic generation is one thing and doing things by hand is another. Both are possible. For best possible results, you’d do it by hand, of course.

Noon’s video

No clue what’s this but there are so many road spline tutorials on YT. Really curious what is your scenario here. Making wild tracks akin to Trackamania’s ones is definitely possible.

Also, when something gets deprecated, it gets replaced with a more robust solution. This usually happens 2-3 versions after a new features gets out of Experimental. Is there something specific you have on your mind?

I think he’s talking about Alan Noon from Epic - https://www.youtube.com/watch?v=N0CeLsI-sr8.

Ah, thanks.

I’ve used that without knowing it was a thing. I’ll just add that these days you can directly copy paste data into arrays so there may be no need for a data table if you’re after something simple.
