Ground-plant variant 1 previously used six upright leaves with only four triangles per lamina. It had no explicit leaf-material tag, and its far tier became four unrelated fronds. This pass changes only that ground species: neither the larger understory plants nor bushes nor split/litter ground variants are redesigned.
GroundBroadleaf defines six deterministic leaf identities with unequal dimensions,
small azimuth variation, pigment and phase. Far retains sources 0, 1, 3 and 4 exactly,
including their petioles. Near samples seven rows/five columns; far samples three
rows/three columns of the same tapered, cupped lamina. The leaf starts exactly at
the existing petiole endpoint. Their shared wind weights agree at that attachment.
Analytic-profile normals and normalized material coordinates enable the existing
filtered vein, age and daylight response instead of the untagged flat fallback.
The 2026-10-15 follow-up adds two narrow, brighter emerging leaves to the near rosette at different heights and azimuths. One of them is retained by the far mesh. This breaks the low oval ring into a layered tropical-plant silhouette and makes the existing petiole/midrib structure readable without another instance, shader, material, buffer or draw.
No new shader, texture, vertex format, per-frame buffer, plant placement, draw pass or framework change is needed. The BasicEffect fallback gets the geometry but not the custom leaf lighting/material. Far geometry is still coarse, and omitting two leaves is not an invisible LOD morph. Other ground species still have mismatched near/far identity and angular silhouettes; this pass must not be described as fixing all vegetation.
The current near mesh has 312 vertices / 400 triangles (the first curved revision was 234 / 300; originally 54 / 36), and far has 65 / 50 (first revision 52 / 40; originally 24 / 16). The latest two-tier addition costs 4,732 static vertex bytes plus 660 index bytes. Total jungle static vertex payload is 2,621,944 bytes. Index storage and per-frame vertex processing are separate costs. The extra geometry follows the existing species/LOD batches, not one draw per leaf. Physical-device cost remains unqualified.
GroundBroadleafTests.cpp samples 12,726 positions/normals across all six source
leaves: bounded finite geometry, exact petiole attachment, closed taper endpoints,
unit normals, independent tangent-orthogonality checks, cupped cross sections and
invalid-input rejection. Far source identities are exact and unique. Runtime mesh
validation checks finite attributes, index bounds and the existing placement footprint.
All 32 non-display groups pass after the new camera is integrated (23.13 s).
The new command-line negative regression initially expected the wrong wording for
a missing capture path. It was corrected to the existing application diagnostic;
the application error behavior did not change. CTest now expects 25 invalid
invocations, including parsing ground-broadleaf before rejecting the missing path.

A comparison crop at (0,120), 410x280, selected a neighboring bush;build-probe/island-ground-broadleaf-comparison.pngis not evidence of this species' improvement. Retain this note to avoid misinterpreting the image.20261009T085644.169508Z-ground-broadleaf: dedicated new camera selects variant 1 at normal player eye height, without hiding other plants or changing the scene. Its inspected 1280x720 frame shows the curved blades, fine material veins and attached stems. It is a current-state review, not a matched before/after image or a proof of perceptual realism. Grass and coarse neighboring bushes remain visibly stylized.
The dedicated view is available as --viewpoint ground-broadleaf and in the browser
smoke shell. Native/Web checks require its actual target-variant diagnostic, not
merely a generic content-loaded marker. It is added to the focused Web vegetation
matrix. No hardware GPU run is authorized by these examples; use the monitored
software launchers during the open AMDGPU incident.
The contained SwiftShader six-view vegetation matrix
build/browser-software/20261009T090051.635173Z-chrome-vegetation/ passes grass,
jungle, fronds, east clearing, clearing edge and ground broadleaf, each with 60
presentation intervals. All report zero GL error and no context loss; live/final
kernel deltas are empty. The ground-broadleaf image after simulation is inspected
and retains the curved targeted plant. Wind is active; these images are not a
frozen pixel comparison. This matrix does not renew the full input/lifecycle suite
or measure physical-device frame times. Package: 13,883,396 raw / 6,964,284 gzip bytes.
Both ABI assembly/lint runs pass (5 s each), with default ARM64-only packaging
restored. The isolated API 35 KVM/SwiftShader view
build/android-software/20261009T090756.767342Z-ground-broadleaf/ passes, app PID
1773 / entry TID 1880, first-draw total 14,121.283 ms. The inspected 1280x720 frame
shows the same targeted plant and touch overlay. Kernel deltas are empty; the
owned emulator exits zero. Touch/lifecycle tests were not repeated, and ARM64
runtime is unverified. Current APK identities are in build-android.md.
The final native dense-jungle capture 20261009T091041.337804Z-jungle also passes
and is inspected, with empty kernel deltas. All 32 non-display groups pass again
in 20.34 s. No owned graphics processes remain and the hardware stop latch is
unchanged. These are software scene checks, not a fix or qualification of the
unresolved AMDGPU incident. Builds use the existing trees, shared ccache and two workers.
Inspect the far representation during real camera travel; source identity alone is not a screen-space coverage measurement. Improve split ground leaves and near bushes, which remain prominent angular forms, then review overall density/composition. Preserve the same plant-specific QA discipline when choosing comparison crops.
Exact-final native evidence
build-consumer/software-captures/20261015T051834.575594Z-ground-broadleaf passes with 234 colour
bins, 23.14 luminance deviation and 99.52 spatial contrast. The inspected image shows the taller
bright emerging leaf, smaller offset unfurling leaf, mature cupped blades and attached petioles.
The lower, closer QA camera is inspection-only and does not affect play.
