The previous talkie-overlay refactor lost the rest/active behaviour and
left the radio-shake CSS animation running constantly. Restore the
intended polish:
- Position lerp between TALKIE_REST_Y (idle) and TALKIE_ACTIVE_Y
(raised when narrator is speaking) with a subtle floating bob.
- Subtle z-axis float at idle, faster shake when active.
- Gate the CSS radio-shake on the new --active modifier so the talkie
is calm when no narrator dialogue is playing.
- Keep the face-camera rotation [0.18, PI, -0.08] from the original
overlay version.
Visibility still kicks in at the reveal step (no regression on the
recent fix).
Shadows still go missing intermittently despite the per-frame
needsUpdate fix. Add temporary console logs to narrow down the cause:
- [shadow:mount]: one-shot snapshot of renderer shadow flags and a
scene.traverse count of meshes with castShadow / receiveShadow at
Lighting mount time.
- [shadow:tick]: every 2s during useFrame, log shadow map enabled flag,
autoUpdate, sun.castShadow, sun intensity, shadow map texture
presence, sun and target world positions, and renderer draw calls.
To be removed once the root cause is identified.
Default visualization was unreadable because every node from depth 0 to
maxDepth was rendered with rainbow-coloured edges. Add three filters
exposed in the Debug folder:
- Octree Leaves Only (default true): skip internal nodes
- Octree Min Depth (default 4): hide the largest enclosing boxes
- Octree Opacity (default 0.35): tone down line density
Also skip nodes without triangles, drop the per-depth HSL palette in
favour of a uniform cyan, and bump default Octree Max Depth to 8.
Regression introduced by the narrator-video revert (1ad0c4d): the talkie
overlay was hidden whenever no narrator subtitle was active. Restore the
prior behaviour where the talkie stays visible from the reveal step
onward and only the --raised modifier and signal lines depend on the
active narrator dialogue.
Update three-debugging.md to reflect that the shadow intermittence
is resolved by explicit sun.shadow.needsUpdate = true at mount and
in useFrame after updateMatrixWorld.
Restore sun.shadow.needsUpdate = true at mount and in useFrame
after updateMatrixWorld. Lost during SHADOW_CONFIG centralization.
Matches develop's belt-and-suspenders pattern; autoUpdate alone
is insufficient because the sun follows the camera (matrix dirty
every frame) and three.js can skip shadow map re-render.
- Drop SceneShadowWarmup section, document centralized shadow config.
- Document the localized Suspense boundaries in World.tsx.
- Document the new player model and octree debug visualizations.
- Open note about intermittent first-load shadow rendering.
Late asset loads inside GameStageContent (e.g. EbikeSpeedometer's
useTexture) and the spawn-player block were bubbling Suspense up to the
root boundary in pages/page.tsx, which unmounted World mid-load and
triggered a redundant octree rebuild + shadow re-config. Localize the
suspension by wrapping each block in its own Suspense fallback.
Also mount DebugOctreeVisualization conditionally on the new debug
toggle.
- Show Player Model: render the main character GLTF in camera-local
space so it stays visible at any pitch.
- Show Octree: overlay the collision octree as colored line segments,
one wireframe per spatial cell, colored by depth.
- Octree Max Depth: cap recursion to keep the scene readable.
- Extract SHADOW_CONFIG into lightingConfig.ts (bias=0, normalBias=0,
cameraSize=95) matching the historically working values from develop.
- Drop SceneShadowWarmup; rely on sun.shadow.autoUpdate=true for
steady-state refresh.
- Enable cloud castShadow and traverse Ebike meshes for cast/receive.
Strip the 'porte' mesh from the cloned scene used to build the la fabrik
collision octree. The wall geometry already has a doorway cutout, so
removing the door slab leaves the opening passable. The visual model is
rendered separately by MergedStaticMapModel and is unaffected.
Drops the stop-gap LA_FABRIK_COLLISION_Y_OFFSET added during debugging.
Reverts the manual shadow refresh throttle introduced in 6d58b90 which
prevented shadows from rendering. Renderer and sun shadow now use
autoUpdate=true and a per-frame needsUpdate=true pulse, matching the
behaviour that produced visible shadows before that commit.
