I've been testing my new rollercoaster and what happened is sometimes in works every time and other times in never works. i figured out that it was because of the roughness of the ball. So I used sandpaper and i "sanded" the metal ball I was using and it legit went 20-25 cm every single jump. Did this happen to anyone else?

Most of my jumps are 18cm and I don't plan on making them longer even though the ball can go that far but I guess I just have to sand the ball a little less.

From what I've seen a lot of the variance comes from the nature of the coaster, because it is at such a small scale such small variances can have a huge effect on where the vehicle could land, and the variances could be caused simply by running the vehicle through the coaster.

Your metal ball was rough? I can see my reflection in mine. What grit sandpaper can grind steel off?

Use steel wool and a dremel

HAH i used 220 sandpaper and I just scratched it up and I couldn't see my reflection
