These three values seem to combine to determine whether track is visible through other track.

When said value is greater than 0, some buildings/signs are visible. Changing the value or the values of the other two may change which buildings/signs are visible. | These three values seem to combine to determine whether track is visible through other track.

- Bit 31
- Track surface: appears to be same effect as bit 22: solid block that can't be driven on
- Wall: when unset, walls are outside of the shoulder, when set walls are between shoulder and center
- Roof: Turns roof vertical and tied to upper outer walls
- Transparent
- Slightly darker than complete transparency (not the same as a full palette texture index 0 texture would be with the partial transparency bit set)
- Only works when a texture is not applied
- Back
- Toggles application of a different texture on the outside face of walls
- When a BACK is set, texture will be the BACK texture
- Otherwise, no clue how this texture is determined, changes when wall type changes and not in any consistent way, sometimes is broken
- Partial transparency
- Toggles transparency on textures that contain transparent sections, e.g. guardrail
- Turns palette texture index 0 transparent (
#000000
) (not to be confused with the same color at another index) - Only works when a texture is applied
- Texture
- Transparent
- Bits correspond to the index within
PALETTE.PAL
- Palette texture index 0 is "normal" transparency
- Others have some kind of weird inversion effect
- Bits correspond to the index within
- Single
- Bits are just texture index
- Pair
- Bits are texture index of left, index+1 on right
- When apply texture not set
- Bits indicate a solid color corresponding to the index within
PALETTE.PAL
- Bits indicate a solid color corresponding to the index within
- Transparent
These apply for road surface, wall/roof, and outer wall/floor.

Textures are determined by BLD file.
- Index: first 9 bits work just like road textures
- Fixed: Same texture is always applied (index in parentheses)
Shoulder height
- >0: up
- 0: flat
- <0: down
AI line
- >0: left
- 0: center
- <0: right
Grip
- 0: full grip
- 12: ice
Audio
- Index of audio to play when driven over (order in
SOUND.INI
) - 0: no audio
- Above plays when over trigger speed
- Below plays when between ~26 mph and trigger speed
Audio trigger speed
- 200 is about 67 mph
Wall type
- Left and right must exist to draw roof
- -1: not present
Roof type
- -1: not present
Outer floor type
- -2: outer walls even with shoulder, normal solid wall
- -1: no outer walls, can fall off
- >=0: texture indexing with 9 bits as usual
- floor height is based on environment depth
- floor width is based on main track width
- outer walls are attached to edges of floor
- can drive partially off shoulder and bounce off
Environment floor type
- Controls color of the bottom of the void
- Value of geometry currently being driven on determines entire color below the horizon
- First 8 bits are palette color index
- Higher bits are used but none seem to have any effect
Building/Sign offset
- >0: left/up
- 0: center
- <0: right/down
Outer lower/upper wall horizontal offset
- >0: outward
- 0: vertical
- <0: inward
Draw order?
These three values seem to combine to determine whether track is visible through other track. For example, given Bonus 4 with a bunch of buildings/signs over transparent track with transparent track on the other side, when the third value is 0, no buildings/signs are visible. When said value is greater than 0, some buildings/signs are visible. Changing the value or the values of the other two may change which buildings/signs are visible.
Third row
These properties only ever have these values over all 11018 geometry segments of the retail tracks.

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.
Palette (PAL) files

Index 0x00
may be treated as having a fully transparent alpha (RBGA #00000000
). All other colors are fully opaque, including the other black at index 0x70
(RBGA #000000FF
).
