Fox cub is 11 shape lines that grow into 17 shapes, with 5 genes the seed draws, 5 motions on 4 joints.
a chibi fox cub: a round body on four short legs, a big head with a pointed muzzle and tall ears, a fat brush tail with a pale tip; it breathes and wags at rest, trots when a game says walk
Each part rides the one before it, so whoever sits at the end feels every motion at once.
The asset line names the model fox_cub, titled Fox cub. complexity=4 holds it to 70 shapes, 6,000 triangles and 4 draw calls; going past any of them is an error.
A gene, S: a value drawn between 0.9 and 1.1 for every seed. This seed picked 0.952. Every line that reads S follows it.
A gene, coat: a weighted pick from tangerine (3 in 6.5), copper (2 in 6.5), honey or cream (0.5 in 6.5). This seed picked honey.
A gene, pale: a weighted pick from cream (2 in 3) or white. This seed picked white.
A gene, sock: a weighted pick from walnut (2 in 4), redwood or iron. This seed picked redwood.
A gene, earS: a value drawn between 0.9 and 1.15 for every seed. This seed picked 1.033. Every line that reads earS follows it.
A ball, an ellipsoid centred on the origin. It stands at the model's origin. It is a joint, and line 28 swells ±3% and line 32 bobs ±0.02 m: everything on it moves too.
body: the root bone, standing on four legs
A limb, a capsule hanging DOWN from the origin (a joint at the top): arms, legs, necks (rot to aim). It rides body, at (.085*S, -.02*S, 0) in its frame. 4 copies in a centred row, (0, 0, .25*S) apart and a mirrored twin across the parent’s centre line. It is a joint, and line 31 tips ±30°: everything on it moves too.
A ball, an ellipsoid centred on the origin. It rides body, at (0, .16*S, .2*S) in its frame. It is a joint, and line 30 rocks ±5°: everything on it moves too.
head and muzzle
A ball, an ellipsoid centred on the origin. It sticks to the surface of head at (0, -26) (azimuth, elevation).
A cone, a cone (or frustum with r2), base at the origin. It sticks to the surface of head at (0, -12) (azimuth, elevation).
A ball, an ellipsoid centred on the origin. It sits at the end of muzzle. Its outline is half width.
A face, a house face (unlit, never inked) on the parent surface: eyes, mouth, blush, brows. It rides head, at its origin.
A cone, a cone (or frustum with r2), base at the origin. It sticks to the surface of head at (34, 52) (azimuth, elevation). 2 copies and a mirrored twin across the parent’s centre line.
A cone, a cone (or frustum with r2), base at the origin. It rides ear, at (0, .01*S, .022*S) in its frame. There is a set on each of the 2 ear copies, 2 in all.
A ball, an ellipsoid centred on the origin. It rides body, at (0, .02*S, -.2*S) in its frame. A chain of 3, each link riding the last. It is a joint, and line 29 sways ±25°: everything on it moves too.
the brush tail: three links that curl up, a pale tip
A ball, an ellipsoid centred on the origin. It rides tail, at (0, .1*S, -.06*S) in its frame. Only when i==2.
body swells and shrinks by ±3%, once every 3.3 s (.3 Hz). This is the breathe preset: a gentle swell (bodies, chests). Everything on body goes with it.
idle: breathe, wag, look about; walk: a trot (diagonal pairs) with a bob
tail (all 3 copies) turns side to side by ±25°, 2 times a second (2 Hz). This is the wag preset: a quick side-to-side (tails). Each copy runs 0.12 of a cycle behind the one before, so they move in turn. Everything on tail goes with it.
head rocks left and right by ±5°, once every 3.3 s (.3 Hz). This is the sway preset: a slow side-to-side lean (trees, signs, idle bodies). Everything on head goes with it.
leg (all 4 copies) tips forward and back by ±30°, 1.8 times a second (1.8 Hz). This is the gait preset: legs or arms that swing in turn (mirror twins alternate). Each copy runs 0.5 of a cycle behind the one before, so they move in turn. The mirrored twin runs 0.5 of a cycle apart, so the pair alternate. It plays only while the model is in the walk state.
body rises and falls by ±0.02 m, 3.6 times a second (3.6 Hz). This is the bob preset: up and down (floating things, riders). It plays only while the model is in the walk state. Everything on body goes with it.
