I recreated Line Rider in 3D and the result feels cursed

The Mountain King track is back! This is my first time doing procedurally generated mesh terrain in Unity. It was a lot of fun to create, although the result feels a bit unsettling. My character modelling skills could use some work lol. Glad I did it though, because I can apply this technique to other concepts now.
Rough explanation of how I did it:
1. I modded a Line Rider Advanced build to output the position data of all the rigging points on the character and sled to a json file.
2. My script reads the line rider track file and converts it into 3D rect geometry.
3. By reading through the motion data of the character, I basically calculate the derivative at each point, allowing me to calculate normal and tangent vectors to the character's movement. These vectors determine the terrain mesh positions.
4. This part I'm really proud of. I created my own keyframing system for camera movement, allowing me to orbit the camera around the character and smoothly interpolate between different positions in time while tracking the character. There is also a keyframing system for terrain parameters.
5. Random raycasts from the sky little the ground with trees and rocks for extra decoration.

I, also, am an elementary music teacher and love these videos so I created combined video of the 2D and 3D together!! kzbin.info/www/bejne/rH3PiXtuhqaBZpo

[@5MadMovieMakers]

But are the physics still deterministic, that's the question

[@nyri0]

If I understand correctly, it's exported from the 2d game with a mod. Recreating the physics of the original game would be tricky.

[@samvsmedia8680]

If not, this must have been really painful

[@NStripleseven]

If I’m reading the description correctly it says that it just records the points the character is at throughout the song and plays through them, so it’s just as deterministic as the 2d version is.

[@puzzzl]

There are no physics, it's just playback

[@LynxofCP]

My first thought was that maybe if Line Rider were a unity game, you'd be able to create a 3D scene with only 2D physics applied to it (I have messed with this myself and it works fine). Not really deterministic, but quite likely to produce similar enough results, though the cumulative error might not have worked. Seeing the actual answer, I'm actually even more impressed.

[@AriT-u3x]

Oo

[@victoriachang3829]

I know right!

[@nedasbolevicius8676]

This is absolutely sick. Though, I imagine a big factor of why it's so unsettling is the camera movement, while keyframed and smoothly interpolated, looks to be strictly locked onto the rider. At parts such as 0:24, this jumpy movement is really apparent and staggering. Usually camera movement is done with easing, which really helps the flow. Amazing work! Must've took ages.

[@gnash.r]

Maybe because I don't play line rider but just watch these videos, that part looked just as normal to me as the rest of the video, a bit of a different aesthetic but cool to watch nonetheless

[@pianotm]

You're right, the whole thing is awfully jumpy. Tying the camera to the rider with a follow script instead of just making the camera a child of the rider and adding a slight lerp would have really smoothed this out.

[@Sebbir]

What im most impressed with is that you actually got the little guy to move exactly how he does in Line Rider
