# Eight-region start and road-placement review, r405

## Result

The packaged viewer reached `City scene ready` in all eight region selections
on host Chrome/WebGL2. A narrow 12 m check around each selected player start
found no `XB_` building triangle intersecting a road triangle. This verifies
the immediate start area only; it does not certify the streets farther along
each route or the complete Bayview layout.

The visual sweep also confirms these are different scene contexts, not eight
adjacent city tiles. L4RA, L4RB, and L4RD show street or freeway corridors;
L4RC starts inside a covered garage area; L4RF starts in a broad plaza; L4RG
and L4RR show airport-like pavement; and L4RH is an isolated narrow track
without traffic. The route-less L4RH/L4RR scenes remain driveable on authored
pavement, but are not city-road extensions.

## Start-point audit

The diagnostic calls the packaged viewer's `__nfsuFindRoadIntersections`
against the selected start with radius 12. It groups source meshes by placed
object and requires a 3D triangle/triangle crossing; it does not infer that
every projected XY overlap is a collision.

| Region | Free-roam routes | Player start (X, Y, Z) | `XB_` groups crossing road triangles within 12 m |
| --- | ---: | --- | ---: |
| L4RA | 832 | (-865.21, -442.96, 21.59) | 0 |
| L4RB | 99 | (24.01, 743.58, -11.97) | 0 |
| L4RC | 54 | (792.22, -357.29, 29.00) | 0 |
| L4RD | 26 | (487.87, -1351.24, 14.72) | 0 |
| L4RF | 33 | (-1551.76, -2144.25, 18.41) | 0 |
| L4RG | 44 | (2513.97, 461.60, -11.08) | 0 |
| L4RH | 0 | (10.81, -0.50, -0.35) | 0 |
| L4RR | 0 | (-21.97, 11.97, 0.00) | 0 |

The large raw intersection counts seen at 100–160 m were not used to move or
delete geometry. Their samples include road-edge crossings and elevated or
support structures; a single triangle overlap is not proof that an authored
building is misplaced. Route-level checks and direct visual review remain
necessary.

## Host Chrome captures

The eight 960×540 screenshots are fresh packaged-page captures taken after
the loading-panel fade. The XP guest GPU was not used.

This audit does not establish retail scene streaming order, citywide building
placement, or that these eight scene sets should be combined. The current
eight-stream union still produces mismatched overlapping scenery and roads;
the retail active-stream selection remains unresolved.
