Hair dynamics

August 18

Spade's pigtails currently hold rigid to the head. These add secondary motion with a custom spring solver that bakes straight onto the rig, so the result renders on any machine with no simulation cache to hand around. Two things had to be solved together: the tails have to stay seated in the chrome cuffs, and the hair above the cuffs still has to move.

Current

Subdivided, softly limited

The hair mesh went from 10,800 to 57,700 vertices so it can actually draw the curve the rig asks for. Joints swing freely, and where they are held back they are eased rather than stopped, so nothing pops.

Variant

Fully free

Same subdivided mesh, no cap at all. Loosest motion of the set, at the cost of a sharper bend low in the tail on the hardest bounces.

Other approach

Strand rebuild

Rather than deforming the existing hair, this grows roughly 1,100 new locks, each with its own wave, spiral and taper. The original pigtails are hidden underneath.

Getting there
v14

Hard limit

Subdivided mesh, but the bend cap was a hard stop and the middle of the tail snapped against it.

v12

Cuff cone

Tails held in the cuffs by limiting angle instead of freezing them, so the hair on top stays alive.

v10

First strands

Too few, too thick. Read as flat blades.

v09

Heavier damping

Calmed the overshoot, but took the life out with it.

v06

Denser bones

20 joints per tail with a smooth weight falloff. Removed the creasing.

v05

Cuff lock

First attempt at holding the tails in place. Held them, but froze the hair above the cuffs.

02

Fugitive :30

August 8 to 10

A self-directed thirty second test of the whole loop: script, hand-drawn boards, AI stills, animation. Built to measure how much control the AI stage actually gives before the October benchmark. Seven shots, fifteen panels, deliberately narrow camera language. Her face is withheld for twenty-seven of the thirty seconds.

Animatic. Boards cut to the track. Timing runs 5 / 4 / 4 / 4 / 3 / 6 / 4 seconds and lands on the drop at the final orbit cut. Sound on.

First frames

One still per shot beat, not one per panel. Four panels get carried by the video model from a neighbour instead. Every frame was generated from the board panel plus the locked character anchor, so composition comes from the drawing and the character comes from the reference.

Hand-drawn boards

Music box

July 16

The first pipeline test against the creative brief for the music box opening. Ivory and gold box opens on a slow push, ending near full frame on the faceted mirror. Same prompt and reference pack run across different video models to compare control and consistency.

Test 01

Ten seconds, full push through to the mirror.

Test 02

Same brief, different model.

Test 03

Same brief, different model.
