Surface type Pit Transparent
Requires no texture
Flip horizontally Apply texture Texture
  • Texture
    • Bit 0: some sort of offset?
      • For normal textures, left index+1 right index-3
      • For transparent, makes it darker?
    • Bits 1-7: pair index, first texture on left, second on right
      • 00000010 is first pair, 00000100 is second pair, etc

Values

  • AI line
    • >0: left
    • 0: center
    • <0: right
  • Grip
    • 0: full grip
    • 12: ice
  • Surface type
    • 524703 590082 590082 appears to define a moving ramp or at least a surface the car can fly off of vertically
  • Sign type?
    • There are other values that apply signs or do other things
    • -1: none
    • 9: sign in center?

  • 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

Effects

Bonus 7

  • Swapping yaw and pitch: loop
  • Swapping yaw and roll: twisting line
  • Swapping yaw and pitch, roll 90.00000: vertical ring to the left
  • Negative yaw: turnright
