BAT v1.22 — Sequence Packing

Highlights

Pack entire shot sequences in one go. Select a sequence folder, BAT finds the latest published blend files across all shots, traces and deduplicates shared dependencies, and packs everything into a single ZIP.

New features

Blender addon

  • Pack Sequence operator (File > External Data > BAT > BAT - Pack Sequence) — browse to a sequence folder, scan for latest published blend files, review and toggle individual shots, export to ZIP
  • Studio template system — dropdown to select folder conventions per studio (Autour de Minuit, La Cabane Productions). Templates define where to look for published files and which task types are available
  • Progress indicator — cursor progress bar during tracing and file transfer on all pack operators
  • Auto-named output — ZIP filename inferred from the scanned folder name

CLI

  • New bat pack-sequence -t output.zip file1.blend file2.blend ... subcommand for packing multiple blend files with unambiguous argument parsing
  • Old bat pack --sequence still works but is deprecated

Improvements

  • Blender 5.0 compatibility fixes (DNA struct changes for nodes, modifiers, sequencer)
  • Console logging for all pack operations (trace progress, asset counts, transfer status)
  • ZIP write start/finish logging
  • pack-info.txt now lists all blend files when packing a sequence

Bug fixes

  • Fixed folder matching using prefix instead of exact match (e.g. Publish_old could be picked over Publish)
  • Fixed Windows UNC and drive letter path normalization in bpathlib.make_absolute()
  • Fixed os.path.commonpath crash when blend files span multiple drives
  • Fixed progress bar getting stuck on pack failure (missing progress_end() cleanup)
  • Fixed ZIP error handler swallowing tracebacks
  • Added per-shot error isolation in sequence scan (one broken folder no longer aborts the entire scan)
  • Deduplicate blend file paths when same file appears in both positional arg and --sequence

Testing

  • 28 new tests for sequence packing (tests/test_sequence_pack.py)
  • 0 regressions on existing test suite
