scenesset 44× in templates and rigs

A (p, q) torus-knot mesh, the classic body for showing off a material and a shaped light: its surface turns through every orientation. Its material comes from its own attributes (`material=<name>`, `fill`, `metalness`, …), not a nested `material`.

look_attextTurns the node every frame so its face (+z; a device's screen, a laptop's front) points at a target: a point `x y z` (mm, world), `#node-id` (that node, live) or `camera` (the lens, live). Its `rotation` and rotation keys are an offset on top of the aim.0×

uptextWith `look_at`: the world direction kept as the node's up, `x y z` (default `0 1 0`).0×
