rig-c/examples

The examples of the rig-c toolchain (@rig-c/core, @rig-c/parts, @rig-c/play), in two halves:

• The corpus — the inputs the toolchain's gates fetch by a pinned commit: demo, wind, scarf, reference-demo, reference-sample, three-quarter and family. Their paths are frozen. @rig-c/parts' scripts/fetch-examples.sh copies files from a commit it pins, and @rig-c/play's fixture pins a commit too, so a change to a corpus directory reaches a consumer only when that consumer moves its pin.
• The trials — what was tried with the toolchain to answer "does this work?", kept whether it passed or failed, under trials/ (see Trials).

This repository was rig-c/parts-examples until 2026-10-23. Links and records that still name rig-c/parts-examples refer to it; GitHub redirects them.

For each standalone character, the corpus holds the painting, the two images See-through was fed, and the two See-through layer sets that came back. rig-parts tracks the light half of each example — the character config, the proposal, the reference implementation's outputs and small contact sheets — under examples/<key>/, and fetches this repository into its gitignored examples/<key>/inputs/.

The standalone input examples listed under “Layout” were generated for publication. Their paintings are generated images of original characters, made from public checkpoints with no LoRA and no text naming or describing any existing character; they depict no third-party character. The generation records and checkpoint credits below concern those standalone examples.

Family: repairing the result

Office	Homewear
Swimwear	Uniform

Four separately labeled transparent previews use the current twenty serving rigs, with the same breathing, gentle breeze and deterministic blink. Each README preview preserves the existing office presentation: 960×832, 67 frames, 3.333 seconds and quality80 across all four outfits. Render recipe · Per-outfit frames, timing, sources and loop proofs: office · homewear · swimwear · uniform. The renderer gives no closure verdict; the decoded last→first step is no larger than the largest step between adjacent frames, and the one-period endpoint difference is reported. Serving art, mesh, physics, motion, player and camera are unchanged.

The Family case study follows five characters from a group painting through repairs to their alpha edges, mesh bindings and physics. These matched Naru frames show one repair: restoring the source edge after a low-resolution binary mask had turned it into steps.

Family has a separate group-image and repair history; the standalone examples' checkpoint and no-LoRA statements do not describe its source. Its later Naru rearhair completion is new generated artwork, distinct from the source-backed edge repairs.

Before	After

The study records rejected fixes, measured motion conditions and remaining limits, including where alpha was inferred or new artwork generated. The Family guide includes the local interactive viewer.

Trials

A trial is one directory trials/<yyyy-mm-dd>-<slug>/ whose README states the question, the inputs and their licence, the exact commands and tool pins, the measurement, a PASS, FAIL or PARTIAL verdict, the alternatives rejected and the limits. trials/README.md is the convention and trials/TEMPLATE.md the skeleton. A trial never edits a corpus directory.

Paths inside meta.json (image) are relative to the character directory. painting.png still carries the ComfyUI workflow it was generated by, in its prompt text chunk; it is left there as provenance.

The six characters:

key	seed	chosen from	See-through layers	notes
demo	71006, then a hand-detailer pass	16 candidates over two checkpoints and three poses (candidates.json), read by eye at the hands	29 full + 29 head	the README character from rig-parts issue #227: twin tails, a bow, sleeves and a short layered skirt, arms held away from the body so the hands are painted apart and open
scarf	72004 (the same six seed numbers as reference-demo's shrine variant, under a different prompt)	6 seeds (candidates.json)	29 full + 29 head	shoulder-length black hair, a very long red scarf with both ends hanging free, a knit sweater and a pleated skirt: a hanging element the others lack
reference-sample	70011	12 seeds in two batches	29 full + 29 head	the plain fixture: the reference rigged it from its own proposal with no hand edit. Published as sample until rig-parts issue #227
reference-demo	71004	18 candidates over three prompt variants (candidates.json)	29 full + 29 head	the reference implementation's twin-tail character with clasped hands; the README character until rig-parts issue #227 took it off display for its malformed fingers. Published as demo until then
three-quarter	250011	10 seeds in two batches under two pose wordings (generation.json), read by eye at the face	29 full + 29 head	the head turned toward image left and tilted, painted to read rig-parts' head-frame turn figures against the frontal faces (rig-parts issue #250); inputs only, no rig-parts example reads it yet
wind	372108	24 seeds under three wordings (candidates.json), screened by rig-parts painting, the seven best re-read with eye-placed joints	29 full + 29 head	a figure for wind interaction (rig-parts issue #372): very long twin tails wrapped in red ribbons and a wide two-layer skirt, arms and legs held apart so the painting passes rig-parts painting

reference-demo and reference-sample are the two characters the reference implementation ran: rig-parts keeps them as fixtures, compared against that implementation's outputs, and no longer shows them. Their files are as they were published under demo/ and sample/ (the records inside still say "key": "demo" and "key": "sample", the key their rig-parts configs keep, because the reference's outputs name the skeleton after it).

How they were made

Painting (reference-sample, reference-demo, scarf). ComfyUI, checkpoint ponyDiffusionV6XL_v6StartWithThisOne.safetensors (Pony Diffusion V6 XL, version "V6 (start with this one)"), no LoRA, no trigger word. Sampler euler_ancestral / normal, 30 steps, cfg 6.0, latent 832x1216, then 4x-AnimeSharp.pth and a lanczos x0.5 downscale to 1664x2432. ControlNet controlnet-openpose-sdxl-1.0.safetensors on a stand_clasp skeleton (standing, hands clasped in front of the waist), strength 0.8, start 0.0, end 0.7. Each character's generation.json has the per-seed figures the seed was chosen on and the reason for the choice.

scarf differs in three things. Its control skeleton is stand_sides (standing, arms relaxed at the sides) instead of stand_clasp, at the same strength 0.8, start 0.0 and end 0.7. It was painted by rig-parts' own rig-parts comfy paint rather than the reference implementation's generation script, so its pose words are the skeleton's own and its positive has no "feet visible, shoes". Its seed was chosen on a different test, written in its generation.json: refuse a painting with a border pixel whose minimum channel is 200 or less, then fewest rig-parts layers WARN lines, then most layers, then lowest seed. Checkpoint, sampler, steps, cfg, latent, upscaler and downscale are the same as above, read from the workflow embedded in its painting.png.

Painting (demo). Painted by rig-parts comfy paint like scarf, on a different checkpoint and pose, then given a hand-detailer pass as a second step; demo/generation.json records both steps.

• Checkpoint hassakuXLIllustrious_v13StyleA.safetensors (Hassaku XL (Illustrious), version "v1.3 - Style A", CivitAI model 140272, version 1240288), no LoRA, no trigger word. Sampler euler_ancestral / normal, 30 steps, cfg 6.0, latent 832x1216, seed 71006, then 4x-AnimeSharp.pth and a lanczos x0.5 downscale to 1664x2432.
• ControlNet controlnet-openpose-sdxl-1.0.safetensors, strength 0.8, start 0.0, end 0.7, on the pose file demo/pose.json (rig-parts issue #198): standing, arms held away from the body, the wrists at (206, 590) and (626, 590) on the 832x1216 canvas, clear of the skirt. Its pose words ask for the same: "arms away from body, hands apart away from skirt, open hands, relaxed fingers".
• Hand detailer: one ComfyUI graph (demo/detail_graph.json), Impact Pack MaskToSEGS over demo/detail_mask.png — two 201x161 boxes, one per hand, drawn by eye, because the box has no hand detector — then DetailerForEach with the same checkpoint and prompts plus ", detailed hands, five fingers" on the positive: seed 71006, 20 steps, cfg 6.0, euler_ancestral / normal, denoise 0.45, guide size 512, max size 1024, feather 5. The painting step's own output is not published; comfy paint reproduces it from the record. painting.png carries the detailer's graph in its prompt text chunk.
• Chosen by reading each candidate's hands at full resolution (demo/candidates.json, one line per image). The selection rule the other characters record — fewest layers WARN lines — cannot see fingers, and no figure was computed to choose.

Painting (three-quarter). Painted by rig-parts comfy paint on demo's checkpoint, Hassaku XL (Illustrious) v1.3 Style A, with demo's sampler, steps, cfg, latent, upscaler and downscale, seed 250011, no LoRA, no trigger word and no control skeleton: an OpenPose body skeleton carries the face's points and would hold the face frontal, so the pose words alone turn the head. Its See-through inputs were cut with rig-parts inputs' geometry by a short script (the full input the painting at x 384 with 384 px of white either side, the head input a 540x540 crop at [249, 0, 789, 540], the box rig-parts propose --head-box proposed after shifting it 24 px down), both RGB; its generation.json records the prompts, the ten seeds and how 250011 was chosen.

Painting (wind). Painted by rig-parts comfy paint on demo's checkpoint, Hassaku XL (Illustrious) v1.3 Style A, with demo's sampler, steps, cfg, latent, upscaler and downscale, seed 372108, no LoRA, no trigger word and no detailer pass, to be a figure for wind interaction that passes rig-parts painting (rig-parts issue #372).

• ControlNet controlnet-openpose-sdxl-1.0.safetensors, strength 0.8, start 0.0, end 0.7, on the pose file wind/pose.json: demo's pose file with the head, neck and shoulders unchanged and the limbs moved apart, the wrists at (168, 540) and (664, 540), 72 px above the hips' line, the knees 128 px apart and the ankles 180 px apart on the 832x1216 canvas, so the arms, the hands, the knees and the ankles each have background between them.
• Twenty-four seeds under three wordings of the identity and costume (wind/candidates.json), each screened by rig-parts painting on the pose file's joints scaled to the painting: 15 passed. The seven best were re-read with the wrists, knees and ankles placed by eye at full size, and all seven passed; three of them carry a frill or a bow on the elbow, which the check does not read.
• 372108 was chosen from those seven for the wind figure: its ribbons wrap the twin tails, where free ribbon arcs would become the rest shape a physics constraint swings from; it has the widest two-layer skirt; its tails hang behind the figure, not painted already swept out as if blown. wind/generation.json records the reasons, the prompt heads comfy paint puts in front of every prompt, and the eye-read painting output.
• See-through inputs cut by rig-parts inputs' geometry: the full input is the painting at x 384 with 384 px of white either side, the head input a 1014x1014 crop at [310, 0, 1324, 1014], the box rig-parts propose --head-box proposed (it ran 184 px above the top edge and was shifted down at the same size). Both are RGBA with every alpha 255.

Layers. See-through, run through the ComfyUI-See-through wrapper at tag 0.5.0 (commit 98d754bf04f668647919ab750eccb0e0640faa81, as installed on the machine that ran it; meta.json itself carries no wrapper version), resolution 1024, 30 steps, seed 42, offload on, LaMa off. Two runs per character: full on the white-padded painting, head on a square crop around the head. Each run's elapsed seconds are in its meta.json.

scarf's, demo's, three-quarter's and wind's runs were queued by rig-parts comfy seethrough with the same settings (resolution 1024, 30 steps, seed 42, offload on, LaMa off, as each meta.json records); the wrapper version installed for them was not recorded. Its See-through inputs were cut by rig-parts inputs: the full input is the painting at x 384 with 384 px of white either side, the head input a 370x370 crop at [639, 144, 1009, 514] (x0, y0, x1, y1 in painting pixels; reference-demo's is 790x790). Both are RGBA with every alpha 255, where the two reference characters' are RGB. demo's were cut the same way: the full input is the painting at x 384 with 384 px of white either side, the head input a 1125x1125 crop at [268, 0, 1393, 1125], the box rig-parts propose --head-box proposed (it ran 269 px above the top edge and the command shifted it down at the same size).

The strings of reference-demo's other two variants (shrine, gothic) are in reference-demo/candidates.json, beside the figures their seeds were measured on. The first six reference-sample seeds ran with a shorter negative, which reference-sample/generation.json states.

Terms

The generated images and JSON in this repository are released under the MIT licence (LICENSE).

The generation records and checkpoint credits in this section concern the standalone corpus examples only; Family's source is described in family/README.md, and each trial's README states where its inputs came from and under what licence. A trial commits only files that may be released under LICENSE; anything that may not stays out, and the trial's README says what was withheld.

Each checkpoint's own terms are its publisher's.

How rig-parts fetches this

bun run fetch-examples in a rig-parts checkout runs scripts/fetch-examples.sh, which clones this repository at the commit the script pins — never a branch — and copies, for every examples/<key>/ of rig-parts that has a counterpart here — the same key on both sides, so rig-parts' examples/reference-demo/ reads reference-demo/ here — painting.png, inputs/* and layers/ into examples/<key>/inputs/. It keeps any file already on disk, prints what it copied and kept per character, and names any rig-parts example with no counterpart here. A new commit here reaches rig-parts only when the pin there is moved.
