thanks for playing, already checked your video and yours look really good. Did you use some form of curve for the track too? I used the derivative of my curve and turn that vector 90 degree so it's perpendicular on the track, like I position the bee and create the tracks just in another axis. Will be playing yours and a view others when I got my oldest kid to sleep in his new bed, might take a while :)
I created my tracks in blender so I had to use some funky methods to work out which way up my bugs should be, I watched this tutorial which suggests using a bunch of raycasts in different directions and then aggregating the surface normals - it does lead to some weird behaviour sometimes though (bugs falling sideways or up when they’re far enough from the ground)
