{"params":{"colorway":{"type":"choice","default":"harness-brass","label":"Colorway","describe":"curated kit-coherent scheme, each carrying leather plus three distinct metals so no fitting shares a hue with the thing it holds: harness-brass is dark saddle leather in a brass plate with a bronze ring, a gold cog crown, blackened-iron fittings and steel rivets; tan-copper a tan belt on a copper plate with the same gold crown; black-steel a cold blackened harness in greys with a white-steel crown; pewter-tan tan leather on pewter and iron with bright steel rivets and a gold crown","options":["harness-brass","tan-copper","black-steel","pewter-tan"]},"leather":{"type":"color","default":"#5A453B","label":"Strap","describe":"albedo of the leather and nothing else: BOTH lapped tongues of the belt \u2014 the one clamped in the plate's guideway and the one that runs over the ball of the thumb and the knuckle to where it dies into the ring's lug \u2014 so the harness can be re-dyed in one knob without touching a piece of metal and without the splice showing as a change of hide. The darkest and largest zone on the part by design, and the line the whole asset reads as at a distance"},"plate":{"type":"color","default":"#B8860B","label":"Anchor plate","describe":"albedo of the brass: the riveted anchor plate on the back of the hand, the guideway cut down its deck, and the fat eye seated on the thumb's knuckle that the strap runs through. The dominant metal mass and what the harness reads as from across a room"},"band":{"type":"color","default":"#CD7F32","label":"Ring","describe":"albedo of the wide faceted band round the thumb's first phalanx, the strap's far anchor. Its own knob so the ring can be a different metal from the plate at the other end of the same strap, which is how the kit mixes brass and bronze on one object"},"cog":{"type":"color","default":"#FFD700","label":"Cog crown","describe":"albedo of the polished brass: the oversized teeth of the cog crown standing on the thumb ring, and the single brass rivet through the clamp where the strap meets the plate. The asset's one saturated accent and its brightest zone \u2014 the eye should land on the cog first and follow the leather back to the rivet, so keep whatever goes in it brighter than the plate and the ring"},"iron":{"type":"color","default":"#2C3E50","label":"Fittings","describe":"albedo of the blackened-iron fittings that HOLD the leather: the clamp bar pinning the hand's tongue in the plate's guideway, the keeper straddling the lap where the belt turns onto the ball of the thumb \u2014 which rides the ball with the leather it holds, so it stays on the hand through a pinch \u2014 and the saddle lug on the ring the far tongue is riveted into. The part's one cool hue and deliberately its DARKEST tone, so the ironwork reads as holding the strap rather than competing with the cog for the eye"},"stud":{"type":"color","default":"#A9A9A9","label":"Rivets","describe":"albedo of the small bright hardware: the proud rivet heads down the anchor plate's two rails and the pair through the ring's lug. Steel by default and deliberately COOL, which is what leaves the cog crown the only warm-bright thing on the part"},"hand":{"type":"choice","default":"left","label":"Hand","describe":"which hand the harness is built for: right is the exact mirror \u2014 anchor plate, clamp, keeper, brass eye, ring and cog crown, every rivet \u2014 so it fits a tracked right hand's thumb. The part is built entirely on the thumb's own half of the hand, clear of the centre line, so the mirror is a whole part on the other side rather than a build that overlaps itself; variant-hand-right.png is the proof and shows all of it","affects":"geometry","options":["left","right"]},"girth":{"type":"range","default":1,"label":"Girth","describe":"the flesh thickness of the hand it is fitted to, from 0.85 a slim bony hand to 1.3 a chunky cartoon paw. The harness is re-solved rather than scaled: the plate keeps its 28 x 16 mm slab, the strap its 5.6 mm section and the ring its 8.6 mm band at every value \u2014 what changes is where the plate's thumb-side rail has to stop inside the hand's own dorsal face (that face narrows 5 mm across the range), how far the leather has to climb over the ball of the thumb, which stands 12 mm proud of the palm's arris at the chunky end, and how far round the thumb the ring has to reach","affects":"geometry","min":0.85,"max":1.3,"step":0.05},"knuckles":{"type":"range","default":1,"label":"Knuckles","describe":"how bony the joints of the hand it is fitted to read, 0.3 smooth to 1.6 every joint a knob. The plate beds on the extensor cords, which stand up to 2.7 mm proud at the high end, and the strap rides over the thumb's knuckle mound rather than biting into it, so a bonier hand lifts the harness rather than being cut by it","affects":"geometry","min":0.3,"max":1.6,"step":0.1},"reach":{"type":"range","default":1,"label":"Reach","describe":"how far back toward the wrist the anchor plate is set, and with it how long the plate and the strap are: 0.78 pulls the plate up to a short 21.8 mm slab with its clamp close behind the nose and 18 mm of leather in the guideway; 1.0 the reference, a 28 mm plate on the wrist half of the back of the hand with a 24 mm tail of leather down its channel; 1.24 sets it right back over the wrist crease as a 34.7 mm plate with the tail running its full length. The plate and the strap REBUILD at the new length \u2014 the plate keeps its seven stations and the strap gains one every 6 mm of channel \u2014 so the triangle count moves with this knob, while the slab, the guideway, the clamp and the rivets stay the same stock at every value","affects":"geometry","min":0.78,"max":1.24,"step":0.02},"teeth":{"type":"range","default":10,"label":"Cog teeth","describe":"how many teeth the cog crown on the thumb ring carries, each one 2.8 mm proud of the band: 6 is a coarse ratchet wheel with wide gaps between fat teeth and the most broken outline; 10 the reference, which reads as a gear at a glance and still shows daylight between the teeth at 64 pixels; 14 a fine-pitched wheel that reads almost as a knurled collar. The teeth are REBUILT at the new count and keep their own width, so the gaps close as the count rises and the triangle count moves with this knob","affects":"geometry","min":6,"max":14,"step":1},"width":{"type":"range","default":0.0056,"label":"Strap width","describe":"the leather's width in metres, and with it the guideway cut down the plate, the clamp's span, the keeper on the wrap, the eye on the knuckle and the lug on the ring, which are all cut to fit it: 0.0044 is a fine watch-strap that leaves the thumb's crown bare either side of it, 0.0056 the reference (about half the thumb's own radius), 0.0070 a broad harness strap that fills the plate's channel and the ring's lug. The leather keeps its 1.6 mm thickness and its 1.4 mm standoff at every value, so this is the strap's proportion, not its scale","affects":"geometry","min":0.0044,"max":0.007,"step":0.0002},"rivets":{"type":"range","default":4,"label":"Rivets","describe":"proud steel rivet heads set in the sunk panels down the plate's two rails, either side of the guideway: 0 leaves the plate a pair of empty panels with only the brass rivet through its clamp, 4 the reference (a pair beside the clamp where a plate is really bolted down and a pair near the nose), 6 a fully bolted mount with a third pair at its waist. Each head is 1.8 mm across and stands 0.9 mm proud of a panel sunk 0.45 mm into a 3.3 mm rail, so it reads by its own shadow from directly above and breaks the plate's outline in the three-quarter","affects":"geometry","min":0,"max":6,"step":2}},"presets":{"harness-brass":{"leather":"#5A453B","plate":"#B8860B","band":"#CD7F32","cog":"#FFD700","iron":"#2C3E50","stud":"#A9A9A9"},"tan-copper":{"leather":"#9C6644","plate":"#C04000","band":"#CD7F32","cog":"#FFD700","iron":"#2C3E50","stud":"#7F7F7F"},"black-steel":{"leather":"#4D4D4D","plate":"#A9A9A9","band":"#E1E1E1","cog":"#F4F4F4","iron":"#2C3E50","stud":"#7F7F7F"},"pewter-tan":{"leather":"#9C6644","plate":"#7F7F7F","band":"#A9A9A9","cog":"#FFD700","iron":"#4F5D75","stud":"#E1E1E1"}},"rev":1792408797,"materials":{"leather":{"kind":"leather","finish":"grain"},"plate":{"kind":"metal","finish":"polished"},"band":{"kind":"metal","finish":"polished"},"cog":{"kind":"metal","finish":"polished"},"iron":{"kind":"metal","finish":"satin"},"stud":{"kind":"metal","finish":"polished"}},"materials_note":"what each colour zone is made of: `kind` and `finish` name a procedural PBR material in https://polyfork.dev/materials.mjs (dressByAlbedo finds a zone by its albedo in COLOR_0).
