cdb trace of LIVE retail (tools/cdb/issue176-floor-light.cdb, binary<->PDB MATCH) PROVED retail applies ALL its dynamic lights — 4 intensity-100 magenta portal lights (d3dIdx 3-6, falloff 6) + the viewer fill (d3dIdx 1, 2.25) — as D3D hardware lights to EVERY Facility Hub cell, every frame, stable. So the faceted purple wedges on the floor are retail-FAITHFUL. acdream did a per-cell SelectForObject sphere-overlap 8-cap for cells, so the portal set could differ/flip per cell. - LightManager.SelectForCell (retail minimize_envcell_lighting 0x0054c170): ALL dynamic lights applied unconditionally (shader range cutoff zeroes non-reaching = D3D hardware range), then nearest static torches fill remaining slots. Wired into EnvCellRenderer.GetCellLightSet. Objects keep SelectForObject (minimize_object_lighting). Pins: SelectForCell_AppliesAllDynamicLights_EvenOutOfReach + _SameDynamicSet_ForCellsFarApart_NoFlap. - Apparatus: [light-detail] gains owner/cell/dyn (pinned the culprit = 2 portal weenies 0x000F4247/48 in 0x8A020118/19, intensity=100 magenta); CellVertexNormals_SmoothOrFaceted_Dump (corridor floor uses SMOOTH per-vertex dat normals, not flat); tools/cdb/issue176-floor-light.cdb. #176 RESIDUAL is NOT this fix. It's a RUNTIME draw z-fight in the seam floor. Eliminated (evidence): NOT lighting (per-light cap + this both no-change), NOT membership (render cell 0x8A020164 stable 100% of 188k frames / 526 angles, res=None), NOT dat geometry (coplanar sweep empty at z=-6 floor incl. cell 0164). NEXT = RenderDoc pixel-history. Full handoff + DO-NOT-RETRY: docs/research/2026-07-06-176-seam-floor-zfight-handoff.md. Suites green: Core 2599 + 2 skip.

$$ #176 floor triangles - retail light-setup trace (2026-07-06)
|
|
$$ Q: does retail set up the DYNAMIC magenta portal light (intensity=100,
|
|
$$ color 0.784,0,0.784) as a HARDWARE light applied to the corridor CELL?
|
|
$$ If yes -> retail's cell floor IS lit by the portal via D3D hardware T&L,
|
|
$$ so the per-vertex wedge pattern is retail-FAITHFUL, not an acdream bug.
|
|
$$
|
|
$$ config_hardware_light(d3dIndex@[esp+4], _D3DLIGHT9* out@[esp+8],
|
|
$$ ulong cellID@[esp+0xc], LIGHTINFO* info@[esp+0x10])
|
|
$$ d3dIdx 1-10 = DYNAMIC (viewer / teleport PORTAL); 11+ = STATIC (wall torch, baked)
|
|
$$ Dumping the cellID lets us see WHICH cell the magenta portal is configured for.
