# Fleet WINDOWMASK material correction · r370

A stock GLB audit found that 27 car models still exported retail material hash
`0x3ed70c43` (`WINDOWMASK`) as `paint_body`; only the earlier 240SX rebuild
used the glass role. The garage exporter now applies that hash classification
across all 29 stock player-car GLBs. The focused audit counts 82 active body
slices assigned to `glass_vehicle`; 13 separately named, source-textured
`REAR_DEFROSTER` overlays remain on their own blended material. No active
WINDOWMASK body slice remains in the paint role.

The full rebuild retains each car's existing powertrain capture and wheel-anchor
metadata in the manifest. The packaged manifest and all 29 GLBs/shadow images
are synchronized with the source export. A loaded packaged Chrome view at L4RA
route 450 shows the 350Z on the marked road. Its active material list contains
multiple `glass_vehicle` batches and its rear defroster remains visible.

This fixes the preview material role, not the retail window shader state. The
current renderer still uses its approximate glass opacity/reflection, and the
body paint remains an untextured neutral preview. See the loaded capture at
