Hi i made this exampledemocapx
its got easing of scroll, scale, and parallax with 2 layers
it also has a follow scroll and at the end the scroll is fixed on the player with platform movement
i think a lot of people are wondering how these things work so i hope this helps!
how this lerp works?:
layoutscale = current scale
1 = target scale
0.5*dt = is how fast it will go from current to target, larger is faster
