art.wick.CatRig

Wick himself — the lighthouse cat's geometry, his bones, and the poses he moves between.

The rig

Every bone's mesh is lofted along +Y, from its joint at y = 0 to its tip at y = length, so a child bone sits at (0, length, 0) in its parent and every joint is one rotation about Z. The cat's belly is local -X and his back is local +X: that is the side his legs reach from, which is what lets the body turn its paws toward a wall by turning the root alone.

wick_rig            the whole body's angle and its stand-off from the stone
  wick_torso        the spine
    wick_neck         wick_collar (brass), wick_lantern -> wick_lens (+ point light)
      wick_head       wick_eye_l, wick_eye_r, wick_nose
    wick_fl_up -> wick_fl_lo      front legs, one either side in z
    wick_fr_up -> wick_fr_lo
  wick_bl_up -> wick_bl_lo        hind legs, off the pelvis
  wick_br_up -> wick_br_lo
  wick_tail1 -> wick_tail2 -> wick_tail3

R.build(root) spawns that tree under an entity and returns the handles. R.apply(rig, pose, rootExtra) writes a pose onto it; rootExtra turns the whole body on top of the pose's own angle, which is how a leap follows its arc and a knocked-off cat tumbles.

Colour

Vertex colour multiplies the material's base colour, so wick_fur holds the PALE value — the belly, the muzzle, the socks — and the per-ring multipliers in this module carry the coat down to charcoal. That is where the tabby banding on the tail and the light chest come from, with no texture to author.

Poses

R.POSES is a table of joint-angle records, in radians about Z, positive tipping a bone toward the belly (the wall) side: cling, grip, kick, fly, reach, land, fall, win, lost. R.blend(a, b, t) mixes two. Nothing here reads the game — game.WickBody chooses the pose and blends toward it.
