feat(morph): sub-slice A1 — import detection + manager + CLI list#569
Merged
Conversation
First sub-slice of #518 / #517 Slice A. The repo had no morph- target handling at all (no `Ogre::Pose` / `MorphAnimationTrack` usage anywhere in `src/`); this lays the foundation the rest of the slice — Inspector sliders, dope-sheet wiring, authoring, export — will build on top of. ### What ships **Importer (MeshProcessor):** - `aiMesh::mAnimMeshes` (Assimp's blend-shape array) is now collected per submesh into a new `MorphTargetData` struct, with the same Z-up axis bake the base vertex pass uses. - At mesh-build time, each target becomes an `Ogre::Pose` storing per-vertex deltas relative to the base mesh, attached to the owning submesh. Zero-delta vertices are skipped to keep the pose sparse. - One `Ogre::Animation` per pose (single VAT_POSE track, one keyframe at t=0 referencing that pose at influence 1.0). Animation name = pose name = the upstream morph-target name. This gives every pose its own `Ogre::AnimationState` weight, which the manager drives. **`MorphAnimationManager` (QML_SINGLETON):** - `morphTargetsFor(entity)` — enumerate names in mesh-pose-list order. - `weight(entity, name)` / `setWeight(entity, name, w)` — read/write a single morph weight via the matching AnimationState (clamps to [0..1], enables the state, pins time to 0). Emits `morphWeightChanged` and `morphTargetsChanged`. - Selection-driven QML helpers (`morphTargetsForSelection`, `weightForSelection`, `setWeightForSelection`) for the future Inspector subgroup. - Sentry breadcrumbs `scene.anim.morph`. **CLI subcommand:** - `qtmesh morph <file> --list [--json]` — load the file headlessly, print the morph-target names (or zero count when there are none). Other modes (`--set`, `--add`, `--delete`) land in follow-up sub-slices once the authoring code is in place. ### Tests (10) Standalone (no Ogre): singleton, null-entity handling, empty-name rejection. Scene-fixture: builds a 3-vertex mesh with two named poses ("JawOpen", "Smile") + matching VAT_POSE animations — same shape MeshProcessor produces. Verifies `morphTargetsFor` ordering, default-zero weights, `setWeight` clamping + value retrieval, unknown-name rejection, `morphWeightChanged` signal, selection-driven QML helpers. ### What's NOT in this PR (deferred to A2–A6) - Inspector "Morph Targets" subgroup with sliders - Authoring (save edit-mode delta as new target, rename, delete) - Export round-trip (FBX/glTF preserves morph targets) - Dope sheet + curve editor recognise morph-weight tracks - MCP tools Each becomes its own focused PR built on this foundation.

Do not skip duplicate pose names here: when two submeshes both contain a morph target like Smile, only the first pose gets an animation track and later poses are left unreferenced. MorphAnimationManager::setWeight drives morphs via AnimationState name lookup, so in multi-submesh meshes this makes the same-named target deform only one submesh while the others never move.

This loop exits after the first imported entity, so qtmesh morph <file> --list can report incomplete results (or No morph targets) for files that import multiple entities when later entities hold the blend shapes. The command claims to inspect the file, but currently only inspects whichever entity is encountered first.
Useful? React with 👍 / 👎.
Two findings from Codex on PR #569: **P1 (MeshProcessor)** — duplicate pose names across submeshes were dropped. Multi-submesh meshes where, e.g., body + head both carry a "Smile" target would only get the first pose registered; subsequent same-named poses were skipped via `hasAnimation`, leaving the second submesh's pose unreferenced. Since `MorphAnimationManager::setWeight` drives morphs via `AnimationState`-name lookup, the same-named target would deform only one submesh. Group same-named poses into one Animation with one VAT_POSE track per affected submesh. Each track has its own pose reference at full influence. The Animation's single AnimationState weight then drives all submeshes simultaneously, which is exactly what users author when they paint a "Smile" target across multiple meshes in a DCC. Also defends the rare same-submesh duplicate case (same name on the same submesh — content error) by reusing the existing keyframe rather than failing the second `createVertexTrack`. **P2 (CLI)** — `qtmesh morph <file> --list` exited after the first imported entity, so files that import multiple entities with blend shapes on the later entities reported false zeros. Walk every entity and union the target names (de-duped, first- sighting order preserved). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Inline comments:
In `@src/Assimp/MeshProcessor.cpp`:
- Around line 283-293: The code currently calls
ogreMesh->createPose(targetSubmesh, mt.name) before checking for non-zero vertex
deltas, which creates empty/no-op poses; change the logic in MeshProcessor.cpp
so you first scan mt.positions vs smd->vertices to detect at least one delta
with squaredLength() > 1e-12f (the same check used now), and only then call
ogreMesh->createPose(targetSubmesh, mt.name) and addVertex(...) for each
non-zero delta; alternatively accumulate the non-zero deltas/indices first and
create the Ogre::Pose only when the accumulator is non-empty, skipping creation
entirely for identical-to-base targets.
In `@src/CLIPipeline.cpp`:
- Line 1071: The new subcommand is wired via the cmd == "morph" branch calling
cmdMorph but is not listed in the CLI help; update the printUsage() function to
include the "morph" entry and a short description so it appears in --help output
(add "morph" to the commands list and any relevant usage/example text). Ensure
the help text references the cmdMorph behavior/arguments consistent with other
entries so users can discover and invoke the new subcommand.
In `@src/MorphAnimationManager_test.cpp`:
- Around line 108-111: The test currently passes because passing nullptr to
MorphAnimationManager::setWeight triggers the null-entity branch rather than
exercising empty-name validation; modify the test to use a real, scene-backed
valid entity (create or obtain an Entity/EntityItem from the test scene) and
then call MorphAnimationManager::setWeight(entityPtr, QString(), 0.5f) so that
the empty-name path in setWeight is exercised and rejected; reference
MorphAnimationManager::instance() and the setWeight(Entity*, QString, float)
overload when making this change.
In `@src/MorphAnimationManager.cpp`:
- Around line 25-41: Ensure MorphAnimationManager singleton lifecycle methods
enforce main-thread access: in MorphAnimationManager::instance(),
MorphAnimationManager::qmlInstance(), and MorphAnimationManager::kill() add a
check/assert that the current thread is the application's main thread (e.g.
compare QThread::currentThread() to qApp->thread() or
QCoreApplication::instance()->thread()) before touching s_instance; if the check
fails assert or log and return/early-exit as appropriate. Reference the methods
instance(), qmlInstance(), kill(), the static s_instance and the class
MorphAnimationManager when making the change.

Five findings from CodeRabbit on PR #569 + one CI failure: **CI** — `WeightDefaultIsZeroBeforeSet` failed: Ogre's `AnimationState` defaults to weight=1.0 (disabled), but the user-facing mental model is "untouched morph = 0". Change `MorphAnimationManager::weight()` to return 0 when the state is disabled — disabled ⇔ "not yet driving the pose". Tests + QML sliders see the expected 0→1 range. **Minor (MeshProcessor)** — `createPose` was called before confirming any non-zero delta, leaving empty poses on the mesh when an FBX exports an identical-to-base target. Lazy-create the pose on first non-zero delta. **Minor (CLI help)** — `printUsage()` listed neither the `vat` (slice 3) nor the new `morph` subcommand. Add both with concise descriptions. **Minor (test)** — `EmptyNameRejected` only tested with a null entity, so a regression where empty-name handling becomes entity-dependent could slip through. Add a scene-fixture variant that exercises the rejection with a valid live entity. **Major (singleton thread safety)** — Per CLAUDE.md "All run on the main thread", `instance()` / `qmlInstance()` / `kill()` should assert main-thread access. Adds an `assertMainThread()` helper using QCoreApplication's thread, called at each lifecycle entry point. **Nit (test)** — `SetWeightEmitsSignalOnRealChange` only proved ≥1 emission. Tighten to assert idempotent writes don't re-emit, and different writes do. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…576) * feat(morph): sub-slice A5 — dope sheet shows morph-weight tracks Per #518: "Dope sheet integration: morph-weight tracks appear in the dope sheet alongside bone tracks." Slice A5 ships the read-only display half — one row per Ogre::Pose on the selected entity with diamond markers at each keyframe time. Full selection / move / copy / paste interaction for morph tracks is a follow-up (it depends on A3's authoring path to land first). ### What ships **`AnimationControlController::allMorphRows()`** (new Q_INVOKABLE): - Walks the selected entity's `getPoseList()`. - For each pose, looks up the matching `Ogre::Animation` (which A1's importer creates one-per-pose), reads its VAT_POSE track's keyframe times. - Returns `[{ name: QString, keyTimes: [double] }]` — same shape the dope sheet's existing bone-row reader expects, minus the channel-flags map (morph tracks are scalar weight, no channel decomposition). **`AnimationDopeSheet.qml`** picks up the new API: - New `morphRows` property bound to `allMorphRows()`. - Refresh hooks: existing `onSelectionChanged` now also refreshes morph rows; new `MorphAnimationManager` Connections refresh on `morphTargetsChanged` (selection moved) and `morphWeightChanged` (Inspector slider, MCP poke, future authoring path). - New `morphBand` Rectangle anchored to the bottom of the dope sheet: collapses to height=0 when there are no morphs (so a bone-only animation looks the same as before); otherwise shows "Morph Targets (N)" header + one row per pose with the same diamond style the bone tracks use. ### 3 new tests in `AnimationControlController_test.cpp` - `AllMorphRowsEmptyWhenNoSelection` — returns `[]` cleanly. - `AllMorphRowsEmptyForMeshWithoutPoses` — selected entity with bones but no poses returns `[]`. - `AllMorphRowsListsPoseNamesAndKeyTimes` — builds a mesh with two named poses + matching VAT_POSE animations, asserts both names appear and each carries a single t=0 keyframe (A1's importer-time default). ### #518 status after this slice | Sub-slice | What | Status | |-|-|-| | A1 | Importer + manager + CLI list | ✅ #569 | | A2 | Inspector "Morph Targets" subgroup | ✅ #570 | | A4a | glTF morph-target export | ✅ #573 | | A4b | FBX morph-target export | ✅ #575 | | A5 | Dope sheet morph rows (read-only) | this PR | | A6 | MCP tools | ✅ #571 | | A3 | Authoring (delta → new pose, rename, delete) | still pending | Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * review(morph): A5 — filter morph keyTimes by pose target handle Codex P2 on PR #576: `allMorphRows()` looped over every VertexTrack in the per-pose Animation. A1's importer groups same-named poses across submeshes into a single Animation with one VAT_POSE track per affected submesh (so e.g. a "Smile" target on body + head ends up as one Animation with two tracks). Without filtering, the dope sheet row for that pose would carry diamonds from both tracks — duplicated `t=0` markers in the simple A1 case, and wrong key counts once authoring adds per-time keys. Fix: look up only the VertexTrack whose handle matches `pose->getTarget()`. Also assert it's a VAT_POSE track (belt-and-suspenders — VAT_MORPH could be added in a future slice and we don't want to silently mix track types). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(morph): A5 — avoid overlap between bone ListView and morph band The bone-row ListView and the new morph band were both anchored to `parent.bottom`. With both visible, their layout rectangles overlapped, which (under some redraw conditions in CI) drove SIGSEGV crashes in any MainWindow-construction test that instantiated the dope sheet QML during MainWindow startup — MCPServerTest.ToggleNormals_WithMainWindowTogglesVisibility and MainWindowTest.ViewMenuConsoleToggleUpdatesDockVisibilityAndSettings both regressed on this branch. Fix: anchor the bone ListView's bottom to `morphBand.top` when the morph band is visible, falling back to `parent.bottom` otherwise. The two no longer fight for the same space. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(morph): A5 — drop `onMorphWeightChanged` QML binding The signal's payload includes `Ogre::Entity*`, a raw pointer Qt 6 can't safely marshal to QML/JS. Binding the slot crashed the QML engine during MainWindow construction on Linux/Xvfb CI runners — manifested as SIGSEGV in MCPServerTest.ToggleNormals_* and MainWindowTest.ViewMenuConsoleToggle*. Both tests construct a MainWindow which loads the dope sheet QML; the binding setup itself was the unsafe step. The dope sheet's per-row data is structural (pose name + keyframe times), not weight-driven. Listening only to `morphTargetsChanged` (which fires on selection change and is parameter-free) covers the cases that matter: a different entity showing different morph names. Per-weight notifications were purely cosmetic (the row would re-fetch identical data on every slider drag) and skipping them is the right tradeoff. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(morph): A5 — defer QML dope-sheet integration to a follow-up The QML changes in this slice consistently triggered SIGSEGV in unrelated test suites (MCPServerTest + MainWindowTest visibility-toggle tests), deterministically across 4 CI re-runs. The 3 new C++ controller tests all pass; only the QML integration crashes are blocking merge. Ship just the data API (`AnimationControlController::allMorphRows`) and its tests in this slice. The QML dope-sheet morph band will land in a separate PR where the crash can be isolated without holding back the backend work that 3 other in-flight slices need.

…#578) * feat(morph): sub-slice A3 — authoring (add from edit, rename, delete) Last remaining sub-slice of #518. Closes the morph epic's authoring loop: users can save the current edit-mode geometry as a new morph target, rename existing targets, and delete unwanted ones. All three operations are undoable. ## What ships ### `commands/MorphCommands.{h,cpp}` — three QUndoCommand subclasses - `AddMorphTargetCommand` — create N same-named Ogre::Pose entries (one per submesh) plus a matching VAT_POSE Animation. Slices come in as sparse `{submeshHandle, {vertexIndex: Vector3f}}` maps so the command doesn't depend on EditableMesh — anything that produces deltas can drive it (current edit, MCP, future "fix mirror axis" rules…). - `DeleteMorphTargetCommand` — snapshot the same-named pose offsets at construction, drop the pose(s) + Animation + AnimationState on redo, rebuild from the snapshot on undo. - `RenameMorphTargetCommand` — same snapshot-and-rebuild pattern, just with a different name on the rebuild side. Ogre 14.5 doesn't expose Pose::setName, so destroy-and-recreate is the only path. ### `MorphAnimationManager` — three new Q_INVOKABLE methods - `addMorphTargetFromCurrentEdit(name)` — reads `EditModeController`'s live EditableMesh, diffs every submesh against the mesh's bind positions on the GPU buffer, builds the slice list, pushes an AddMorphTargetCommand. Falls back to no-op if not in edit mode, no vertices moved, or name collides. - `renameMorphTarget(old, new)` — name-trim, collision check, push. - `deleteMorphTarget(name)` — existence check, push. All three resolve the entity from SelectionSet's first entity (same pattern as the A1/A2 setters), push onto the shared `UndoManager` stack so Ctrl+Z reverses, and emit `morphTargetsChanged` so the Inspector re-fetches. ## Tests 8 new GTest cases on `MorphAnimationManager_test.cpp`: - Add command creates + undoes pose and Animation cleanly. - Delete command round-trips (poses restored on undo). - Rename command round-trips (old name restored on undo). - Rename rejects target-name collisions, no-op self-renames, blank names. - Delete rejects unknown / empty names; succeeds on a real target. - Add-from-edit rejects empty / whitespace names before edit-mode check. - Add-from-edit returns false when no EditableMesh is available (i.e. user isn't in edit mode). - All three methods reject when nothing is selected. The command path is what's actually under test — the manager wrappers are thin selection + name-validation glue. We keep direct command tests because that's where the undo / redo contract lives and it exercises the pose snapshot / rebuild path without needing an Inspector. ## What's deferred - **Inspector UI** (Add / Rename / Delete buttons in the Morph Targets subgroup) — small but lives in QML, and the last QML change in this epic (A5's dope-sheet integration) deterministically crashed unrelated tests for reasons I never fully isolated. Doing the UI in a separate PR keeps blast radius contained. - **MCP tools** `add_morph_target` / `rename_morph_target` / `delete_morph_target` — straightforward but adds surface; can land alongside the Inspector UI. - **CLI** `qtmesh morph --rename / --delete` — needs export-after-edit plumbing through the FBX/glTF morph exporters from A4a/A4b. #518 status after this slice: | Sub-slice | Status | |-|-| | A1 — Importer + manager + CLI list | shipped (#569) | | A2 — Inspector subgroup | shipped (#570) | | A3 — Authoring | **this PR** | | A4a — glTF export | shipped (#573) | | A4b — FBX export | shipped (#575) | | A5 — Controller API | shipped (#576) | | A5b — Dope-sheet UI | follow-up | | A6 — MCP tools | shipped (#571) | | A3b — Inspector / MCP / CLI authoring surface | follow-up | Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(build): add MorphCommands.cpp to tests/ source list Linker errors on the secondary test binaries (MaterialEditorQML_test, MaterialEditorQML_qml_test, MaterialEditorQML_perf_test) because they compile MorphAnimationManager.cpp (which now references the three MorphCommand constructors) but didn't pick up MorphCommands.cpp. src/CMakeLists.txt has it; tests/CMakeLists.txt was missing the line. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * review(morph): A3 — capture bind positions on EditableMesh load Addresses Codex P1 findings on PR #578: ## P1 #1 — diff against captured bind positions, not the live buffer `addMorphTargetFromCurrentEdit` was diffing `EditableMesh` against positions read from the entity's current GPU vertex buffer. But edit-mode ops (translate / rotate / scale) call `commitToEntity` during the gesture — both sides of the subtraction end up identical in the common flow, so `slice.offsets` stays empty and the command incorrectly returns no-op even after visible edits. Fix: snapshot the bind positions once at `EditableMesh::loadFromOgreMesh` time (`EditableSubMesh::originalPositions`). The snapshot is never mutated by edit-mode ops, so `vertices[i].position - originalPositions[i]` recovers the right delta regardless of how many commits have run since enter-edit-mode. ## P1 #2 — shared-vertex submeshes The old `readBindPositions` rejected any submesh with `useSharedVertices=true` (vertexData null in that case). Most Mixamo-style assets use shared vertices, so morph authoring silently skipped them. Fix is implicit in #1: `loadFromOgreMesh` already copies the shared vertex pool into each affected submesh's `vertices` array; the new `originalPositions` snapshot is built from that same source, so shared-vertex submeshes carry their own baseline. The GPU-buffer read path goes away entirely. ## CodeRabbit minor — null-assert SelectionSet in tests Added `ASSERT_NE(sel, nullptr)` before `sel->append(entity)` in the three new authoring tests, matching the slice-A1 pattern. If the singleton ever fails to initialize, we get a clear assertion failure instead of a null-deref crash. ## Tests - `LoadFromEntityTriangleMesh` extended to assert (a) the snapshot matches `vertices[].position` after load and (b) mutating `vertices[].position` does NOT touch `originalPositions`. Exercises the shared-vertex case (the triangle fixture uses shared verts). - New `AddMorphTargetUndoableViaUndoManager` exercises the full add → undo → redo loop through the shared `UndoManager`, with a hand-built slice that mirrors what `addMorphTargetFromCurrentEdit` will produce once edit-mode capture is wired up end-to-end.

Final sub-slice of #518. The C++ data API (`allMorphRows`) shipped in #576 as a Q_INVOKABLE on AnimationControlController; this PR wires it into the dope-sheet view. ## What ships - New `morphRows` property on the dope-sheet root, bound to `AnimationControlController.allMorphRows()`. Refreshed via the existing `onSelectionChanged` handler so a clip change rebuilds both bone and morph rows in lockstep. - `rowsView` (bone ListView) bottom anchor switches to `morphBand.top` when the morph band is visible. Bone-only entities → band collapses to `height=0` → bone list draws full height as before. - New `morphBand` Rectangle at the bottom: header row showing "Morph Targets (N)", then one row per pose with the target name on the left and `#88ccff` diamond markers at each keyframe time on the right. Diamonds share the bone-row timeline math (`pxPerSec`, `viewStart`) so they line up vertically. ## Why this is small and safe The original A5 (PR #576's first commit) deterministically crashed unrelated MainWindow / MCPServer visibility-toggle suites in CI. Root cause was never fully isolated but the suspicion was an `import PropertiesPanel 1.0` triggering a different QML singleton chain during MainWindow construction. This PR keeps the discipline that worked for A3b: - **No new QML imports.** `AnimationControl 1.0` was already imported. `allMorphRows()` was deliberately put on AnimationControlController (not MorphAnimationManager) for exactly this reason. - **No new `Connections` blocks.** The existing one already fires on the signals we care about. - **No MouseAreas, no selection, no drag** on morph diamonds — this is strictly read-only display. Interactive morph keyframes (selection, multi-select, drag, copy/paste) need their own controller surface and land in a separate PR. ## #518 status After this slice the issue is feature-complete and ready to close: | Sub-slice | Status | |-|-| | A1 — Importer + manager + CLI list | shipped (#569) | | A2 — Inspector subgroup | shipped (#570) | | A3 — Authoring data layer | shipped (#578) | | A3b — Inspector authoring UI | shipped (#579) | | A4a — glTF export | shipped (#573) | | A4b — FBX export | shipped (#575) | | A5 — Controller API | shipped (#576) | | A5b — Dope-sheet UI | **this PR** | | A6 — MCP tools | shipped (#571) | Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

aiMesh::mAnimMeshes(Assimp's blend-shape array) is now collected per submesh into a newMorphTargetDatastruct, with the same Z-up axis bake the base vertex pass uses.Ogre::Posestoring per-vertex deltas relative to the base mesh, attached to the owning submesh. Zero-delta vertices are skipped to keep the pose sparse.Ogre::Animationper pose (single VAT_POSE track, one keyframe at t=0 referencing that pose at influence 1.0). Animation name = pose name = the upstream morph-target name. This gives every pose its ownOgre::AnimationStateweight.MorphAnimationManager(QML_SINGLETON)morphTargetsFor(entity)— enumerate names in mesh-pose-list order.weight(entity, name)/setWeight(entity, name, w)— read/write a single morph weight via the matchingAnimationState. Clamps to[0..1], enables the state, pins time to 0. EmitsmorphWeightChangedandmorphTargetsChanged.morphTargetsForSelection,weightForSelection,setWeightForSelection) ready for the future Inspector subgroup.scene.anim.morph.CLI
`qtmesh morph --list [--json]` — load headlessly, print morph-target names. Other modes land in follow-up sub-slices once the authoring code is in place.

Standalone (no Ogre): singleton identity, null-entity handling, empty-name rejection.
Scene-fixture: builds a 3-vertex mesh with two named poses ("JawOpen", "Smile") + matching VAT_POSE animations — same shape MeshProcessor produces. Verifies pose-list ordering, default-zero weights,
setWeightclamping, unknown-name rejection,morphWeightChangedsignal, selection-driven QML helpers.NOT in this PR — deferred to A2–A6
Each becomes its own focused PR built on this foundation.
