Ashen Peak

A one-round fight in the style of Mortal Kombat: side view, health bars, a round timer, call-outs, combos and knockdowns, on a temple court at dusk. The fighters are original: Riku, a quick monk who fights with kicks, against Grimhold, an armoured giant. Krea 2 drew their two designs and nothing else. Every animation frame, the stage, the HUD and the effects were drawn in code, pixel by pixel.

Stage, HUD and effects

Six parallax layers scroll at different speeds as the camera follows the fighters: the sky, far peaks, near peaks with snow lit pink, the temple with swaying lanterns and rippling banners, the courtyard, and plum branches in front. Petals drift across the court.

How the characters stay whole

The goal: characters that never tear. Every frame passed these checks. The agent skill holds the same checks.

Only design pixels. Each limb is the design's own thigh, shin, foot, upper arm and forearm, turned about its real joints (IK with the design's bone lengths). No limb is redrawn, so nothing can "crumble".
Hidden ends are painted. Each piece is completed where others cover it (thigh tops under the belt, the torso under the arms), so a moving joint shows the part, never a gap.
Cloth can't tear. The headband tails, gi skirt and tabard bend by an inverse warp: every output pixel takes a source pixel.
0 pinholes, 0 floating pieces, on all 137 frames. A detector counts enclosed 1–4 px pockets and separate islands. It found fragments stranded at an elbow and a waist wedge opening in leans, both fixed at the source.
Every animation reviewed zoomed against a ground line, then every contact checked on contact sheets of the full fight. That review changed the kicks: the fighters are chibi (big heads, short legs), so a kick tips the whole body back about the planted foot. Punches are kept clear of the face.
The plugin agrees. The plugin renders every frame of all three documents identical to the original frames.

The agent skill

The whole method, as an agent skill: skills/pixel-scene/ in this repository.

SKILL.md: the workflow from design to published page, and the rules.
references/lessons.md: 28 lessons, each with its symptom, its cause and its fix.
references/qa-checklist.md: the frame review.
references/code-map.md: where everything lives.
scripts/: the review tools.

Reproduce it

The fight is in this repository and rebuilds from the two designs with no GPU: about three minutes on a laptop, with Python 3.10+ and Pillow, NumPy and SciPy (requirements.txt). Run from the repository root; everything is written to out/scenes/ashen_peak/. The frames come out identical to the GIF above.

python scenes/ashen_peak/riku.py           # 15 pieces; the stack equals the design (0 px)
python scenes/ashen_peak/grimhold.py       # 14 pieces
python scenes/ashen_peak/riku_anim.py      # 76 frames: "pinholes/specks: none"
python scenes/ashen_peak/grimhold_anim.py  # 61 frames
python scenes/ashen_peak/fight.py          # the 360-tick round: ashen_peak.gif
python scenes/ashen_peak/fsheet.py riku stance,walk,jab 3   # a review sheet with the ground line and pinhole counts

The designs came from scenes/ashen_peak/designs.sh (Krea 2 through scripts/krea.py, needs ComfyUI); the picked ones are in scenes/designs/. The three .pas files are in scenes/pas/. To rebuild them, export.py drives a scratch Unity project with unity/PasBuilder (see scenes/README.md).
