Two objects that went unused in the final game, found within the listing for Soleanna specific objects.
The first one "gliderope" creates a 2D texture dynamically by a vector, while "glidewire" creates a 3D model dynamically by a vector.
When placed in a level, it will create a grind path between two points without needing to edit or create a .path file, though they can only go in straight lines. You can connect two of them together to change directions, but it's finnicky and unreliable to use.
Unlike normal grind rails, the gliderope/wires use the wind rail sound and effect.
Otherwise it's a fully functioning object, possibly used as a placeholder for grind rails that were defined in the .path files later, or as an early version of dynamic grind paths?
Also a fun showcase at how grinding collision cares not for walls.
