- Input action dev_toggle_occluder_obstacle (Ctrl+Shift+K): toggle obstacle off nav source via reparent to World, rebake NavigationRegion3D, sync NavigationAgent3D; physics/process/collision hardening unchanged intent.
- Occluder dictionary keys by instance id; related client fixes and README/project input note.
- Plan and review: PARSED_GEOMETRY_BOTH / runtime geometry removal lesson for future mechanics.
Harden idle settling so flat ground, obstacle contacts, and rare bump-edge cases stop drifting instead of looping corrective nudges. Also resolves the saved review follow-up items and syncs the runtime docs to the final feet-height and idle-anchor behavior.
docs/reviews/2026-04-10-NEON-16-followup.md: Request changes — two
blocking gdlint issues (export var order, line-length on
vertical_arrival_error) plus suggestions and nits.
ground_pick.gd now checks _collider_is_occluder before the walkable
break: when the ray hits a body in the "occluder" group it advances
OCCLUDER_PICK_THROUGH past the hit point and continues, unconditionally
and regardless of OcclusionPolicy fade state. Non-occluder click
targeting is unchanged.
Three unit tests added to ground_pick_test.gd covering occluder ancestry
detection. Plan open questions and module doc updated.
Review verdict updated to Approved; all blocking issues and suggestions
resolved and documented. Add auto-generated Godot .uid sidecar files for
occlusion_policy.gd and occlusion_policy_test.gd.
Fixes review blocking issue: when the follow target is null (freed,
renamed, or path unresolved) or the Camera3D child is missing,
_restore_all_occluders() is now called before returning so geometry
cannot be left stuck semi-transparent.
Adds OcclusionPolicy resource and wires it into IsometricFollowCamera.
Each _process frame, iterative rays from the camera eye to the player
focus detect bodies tagged "occluder"; their MeshInstance3D surfaces are
overridden with a transparent StandardMaterial3D (fade_alpha=0.25, instant).
Materials restore when the body clears the ray. Null-material surfaces
(e.g. the prototype Obstacle with no material assigned) receive a plain
transparent StandardMaterial3D so they fade correctly.
- client/scripts/occlusion_policy.gd — new Resource (enabled, fade_alpha,
occluder_group, occluder_collision_mask, max_occluder_cast_depth,
occluder_count_log_threshold, is_valid)
- client/resources/isometric_occlusion_policy.tres — default instance
- client/scripts/isometric_follow_camera.gd — occlusion_policy export,
_update_occlusion pipeline, _apply_occluder_fade/_restore_occluder helpers,
static occlusion_policy_is_valid guard, _exit_tree cleanup
- client/scenes/main.tscn — Obstacle tagged "occluder", policy assigned
- client/test/occlusion_policy_test.gd — new GdUnit4 unit tests
- client/test/isometric_follow_camera_test.gd — policy guard static tests
- docs/decomposition/modules/E1_M2_IsometricCameraController.md — NEON-27
snapshot + readability demo gate note
- docs/plans/NEON-27-implementation-plan.md — null-material decision recorded
- Link NEON-10/NEON-25–28 under parent NEON-1 in Summary and Jira backlog table
- Document mid-project-only yaw orbit compromise; post-release camera model settled
- Extend CameraState contract and slice/risk notes accordingly
Module/slice grouping below epics is labels on stories only; Feature
work items are not used. Cross-link from jira-git-naming, story kickoff,
and documentation alignment table.
Align plan, client/server README, E1.M1 snapshot, and code review note with
the chosen design: descend bypass favors smooth stepped surfaces; multi-click
around obstacles is OK. NS-24 remains for idle jitter.
