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
- Bit 0: some sort of offset?

3 | small, back upside down, on two legs |
4 | pair of tall flat rectangles space outwards only visible from center, different texture |
5 | giant tall folded boxes, different texture |

7 | WIDE short box |
8 | cube, different texture |
9 | flat square, always face camera |
10 | flat skinny rectangle, always face camera |
11 | flat small square, fixed, same back |
12 | fixed flat square, back upside down |
13 | 4 tall skinny boxes |
14 | tall box with pyramid top, different texture |
15 | flat square, always face camera, same as 9? |

- 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
Length
Given Pulse at its maximum 193 mph on a modified Bonus 4 where all 494 sectors are 1200 long can complete at lap in 28.36 seconds and on the same track but with 50 flat sectors on each side shortened to 100 can complete a lap in 27.41 seconds, 1000 length units is equivalent to 13.45 ft or 4.10 m. Additionally, the rotated portions of the track contribute approximately 0.20 seconds extra compared to flat.
