Empty on some tracks.

Controls geometry that moves and potrudes. Empty on some tracks.

Scale factor?
- Increases the length and height of the "ramp"
- 1 is a bump, 4 starts breaking textures, 6 is huge vertical wall
Angle?
- Lower is flatter, higher becomes trapezoid with longer top
?
- No clue
Timing group
- With otherwise identical config, two bumps with same number move together, with 1 and 2 move oppositely
