Golf cart

Note: Size: 2.56 m long bumper to bumper, 1.20 m wide across the canopy and tyres, 1.85 m to the top of the canopy roof and 2.27 m to the tip of the pennant pole. The tyres are 0.46 m across on a 1.66 m wheelbase and 0.98 m track. The origin is at the bottom centre, the front faces +Z, the driver sits on the +X side, and the tyres rest on y = 0. The GLB has 996 triangles in 38 meshes. Every material is named exactly after a kit palette colour (sunset orange, stage black, soot black, mid grey, warm white, tie-dye, stage black light, stage black dark, grass green); dark wood is only used when genre < 0.5. The exporter writes one material per mesh, so the same colour name appears on several materials: recolour by name. The baked clip scene-motion (6 s, seamless) moves only parts on their own pivots, and the chassis never moves. All four wheels roll 2 whole turns about their axles. Each front wheel sits in a kingpin node that swivels about a vertical axis through the wheel centre. The steering wheel turns 4.5x the road-wheel angle about its column axis. The pennant sways about its pole. The speaker cones pump 12 times per loop (120 BPM). The tyres have 12 facets, so while they roll the contact point rises and falls by up to about 8 mm. The GLB's static node pose is the t = 2 s frame of the loop (wheels slightly steered), because that is when the check exported it; the clip's t = 0 frame is the straight-ahead rest pose. Params are baked into the GLB at their defaults and only change the model when the scene is rebuilt in the viewer. genre (the kit's 'Genre') sets the speaker cab on the rear deck: below 0.5 it is a low dark-wood cab with one cone (acoustic), and from 0.5 up it is a stage-black cab with two cones that grows to 0.6 m tall at 1 (bass-heavy). Below 0.5 the part speaker.cone_1 does not exist. roofHeight raises the canopy, the struts and the pennant. steerAngle sets the steering amplitude of the loop; its 0.3 rad maximum keeps the swivelled tyres clear of the body. wheelTurns sets whole wheel turns per loop, so the loop stays seamless. Only the default params were rendered and checked; the extremes were not captured. The viewer's exposure is 0.9 rather than the direction's 1.05 so the orange does not wash out (recorded as a plan override); this affects the preview only, not the GLB. glb-lint: 0 errors and 5 heuristic warnings. Two come from the per-mesh materials (material count and duplicates). One flags overlaps where the steering-wheel rim, spoke and boss are deliberately nested. One flags parts as 'detached' because each part's meshes sit in their own group, though they all rest on the chassis or body. One flags the 2.35 m lint height against a generic 1 m reference: that number is an axis-aligned box estimate around rotated wheels, and the real height is 2.27 m. The verdict reads UNVERIFIED only because no host requirements contract was supplied. plan-check passes except for its part-id regex, which rejects the hyphens in the slug-based ids this library requires. With the ids substituted it passes. three-check accepts the real ids, and all of them survive the GLB reload.
