scenario-blender-animation

# Blender animation (character and object) Expert animation means every frame on screen is a choice: key poses the audience reads, holds and snaps placed by hand, spacing designed, arcs checked. The Blender Studio stance is to block stepped, spline late and in parts, and judge from the shot camera at real speed. An agent cannot scrub, so it measures instead: per-frame positions, spacing charts, arc checks, framing, an onion-skin image, a curve plot, and a playblast it actually looks at. If a sibling skill named here is missing from your available skills, ask the user to install it (`npx skills add scenario-labs/skills --skill <name>`); unattended, proceed from tool schemas and flag the gap. **REQUIRED BACKGROUND:** scenario-blender-expert (execution channel, review loop, 5.2 API changes). Shot planning, cameras and animatics belong to scenario-blender-previs-storyboard; building the rig to scenario-blender-rigging. Toolkit: [`scripts/bx_anim.py`](scripts/bx_anim.py) (keying, blocking-to-spline, curve checks, measurement, staging, playblast light, knee-pop, flip and balance checks, onion-skin and curve images, one-object `bouncing_ball`; API in procedures.md, tested on 5.2.1) and `bx_review.playblast`. ## Stance (the expert delta) - **Stay stepped long ("Blocking+").** Hjalti Hjalmarsson: juniors spline too early; computer in-betweens are "unintentional interpolated poses" that make notes hard. Keep adding hand-made breakdowns while stepped; splining is short and late. - ...
