Prevu — Changelog

v1.0.0 — Initial Release

UE 5.7 · Win64 · Zachanot LLC

Added

Core data model

  • UPrevuProject root asset with a four-level hierarchy: TArray<FPrevuAct> → TArray<FPrevuScene> → TArray<FPrevuShot> → TArray<FPrevuStep>
  • FPrevuAct struct with name and ordered scene array
  • FPrevuScene struct with name and ordered shot array
  • FPrevuShot struct with duration (frames), notes, tags, thumbnail path, audio clip reference, Level Sequence reference, and ordered step array
  • FPrevuStep struct with label, thumbnail path, and Level Snapshot asset reference
  • UPrevuProject::MarkSequencesOutOfDate / ClearSequencesOutOfDate / AreSequencesOutOfDate transient staleness API, set on every data model mutation and cleared on successful assemble
  • PrevuShotTemplate asset type for pre-configured shot defaults
  • PrevuVocabularyDA data asset for configurable display terminology (Act/Scene/Shot/Step labels, default duration, default frame rate)
  • Blueprint function library exposing key read operations to Blueprint graphs

Slate UI (PrevuEditor module)

  • SPrevuTab — main dockable editor tab, hosts all sub-panels
  • SPrevuHierarchy — Act/Scene/Shot/Step tree with expand/collapse, rename (double-click), drag-to-reorder, and contextual add/remove
  • SPrevuBoardView — thumbnail grid storyboard view, synchronized selection with the hierarchy panel
  • SPrevuShotInspector — right-side inspector showing duration, notes, tags, steps list with per-step snapshot status, audio clip reference, and Level Sequence reference
  • SPrevuToolbar — toolbar with Assemble button (amber tint + re-assemble tooltip when sequences are stale), New Act, New Scene, New Shot, Export, and Import buttons
  • Viewport HUD with letterbox overlay, shot label, and take counter

Sequencer assembly

  • PrevuSequencerBridge::AssembleMasterSequence — builds the full Master → Act → Scene → Shot ULevelSequence nesting from the current data model; the sole path that creates or modifies Level Sequence assets
  • DisplayToTick helper that converts display-frame counts to tick-resolution FFrameNumber values at the correct ratio, applied at all AddSequence sites to prevent the ~1000x duration mismatch caused by passing raw display frames to Sequencer sub-sequence APIs
  • Assemble clears the staleness flag on success; any data model mutation after assemble immediately re-sets it

Thumbnail capture

  • PrevuCapture::CaptureShot — places a SceneCapture2D actor, orients it to the active camera, triggers a render, and writes the result to the shot's thumbnail path
  • PrevuCapture::CaptureBatch — iterates every shot in the project with editor task progress reporting; failed captures are skipped with a log warning

Level Snapshots

  • PrevuSnapshotManager::TakeSnapshot — captures current level state as a ULevelSnapshot and stores the reference on a FPrevuStep
  • PrevuSnapshotManager::RestoreSnapshot — restores a step's snapshot with PrevuRestoreFilter to limit actor/property scope
  • PrevuRestoreFilter — selective restore filter restricting snapshot application to Prevu-managed actors and properties, preventing unintended side-effects on unrelated level content
  • PrevuSnapshotManager::HasSnapshot — null-safe check for whether a step has a valid snapshot reference

Scratch audio

  • PrevuAudioManager — scratch audio recording routed through the engine's Sequencer Take Recorder integration; audio clip references stored on FPrevuShot
  • Integration with the engine Takes plugin (TakesCore + TakeRecorder)

Take management

  • PrevuTakeManager — take numbering and management per shot; take counter reflected in the viewport HUD

Export and import

  • PrevuExporter::ExportToPNG — composites shot thumbnails, names, durations, and notes into a flat PNG storyboard sheet
  • PrevuExporter::ExportToHTML — produces a self-contained HTML storyboard sheet with base64-embedded thumbnails and inlined styles; no external dependencies
  • PrevuExporter::ExportToBundle — serializes the full UPrevuProject to a .prevu JSON file including all metadata, notes, tags, and relative asset references
  • PrevuImportExport — re-imports a .prevu JSON bundle and reconstructs the UPrevuProject data model
  • Export dialog accessible from the toolbar Export button

Plugin packaging

  • Prevu module declared UncookedOnly (not compiled into packaged games); PrevuEditor module declared Editor
