@PvB Spoiler With B on R, tap the grass next to horizontal fence as soon as R starts to walk into the rails. It's not very consistent, but B often ends up on the fence.
@chemi Spoiler: soln match the height of the jump and grass ,when they match click on grass it will do.
@PvB I've been testing in a remake of that part to avoid all the stuff before it, it doesn't work there. It's because of B's directional preference when planning a path.
I did it but reading @Block builder's first Spoiler means it wasn't the intended way so I don't know. I couldn't get close to the ball?
@gmacpro Spoiler You have to trick your way over the two opposing stairs. What worked best for me was walking to the first stairs from pillar R has he starts to walk to under the rails.
Finally finished, @PvB thanks for the hint (by the way, it just works if B is looking to the right). Honestly, I liked the idea in general and the effort you did investigating such amount of movements but the result is really complex and not obvious in my opinion. I can't rate with five stars this time... but thanks for sharing another level!
