turntable

Turntable (Slotted Actions)

A runnable example that keyframes a Z-rotation turntable through the slotted-actions cross-version channelbag path from the slotted-actions-animation skill, and picks the render engine with the version-branch EEVEE-id helper.

Which fix it witnesses: the slotted-actions cross-version helper. On Blender 5.x the channelbag comes from action_ensure_channelbag_for_slot; on 4.4/4.5 from strip.channelbag(slot, ensure=True) (legacy action.fcurves still works on 4.5, raises AttributeError on 5.x).

Run

# Cheap correctness check only (no render) — the CI smoke check:
blender --background --python turntable.py --

# Also render one still (EEVEE on a GPU host; use --engine cycles on GPU-less hosts):
blender --background --python turntable.py -- --output turntable.png
blender --background --python turntable.py -- --output turntable.png --engine cycles

By default it runs only the frame-independent correctness check: it inserts the rotation keys, samples the object's Z rotation at frame 1 vs a later frame, and asserts they differ (the keys drive playback). It exits non-zero on failure — the same check the blender-smoke workflow runs on Blender 4.5 LTS and 5.1. --output additionally renders a still; the full animated loop is a showcase extra, not part of the CI check.
