The same slab outline split at y=-0.02, with each half sheared sideways and given an opposing tilt so the fracture line reads clearly. The rune rides on the upper half only, so it is visibly incomplete, and three shed chips float around the gap. Useful as the failed or half-collected state of the intact stone. Bounding size 0.36 by 0.54 by 0.10 m; metres, +Y up, +Z forward. Origin: free, at the gap between the two halves, where the intact stone centre used to be, because a collectible like this is hung in mid-air at whatever hover height the level needs and a base origin would put it on the floor. The geometry surrounds the origin, reaching 0.269 m below it and 0.269 m above it. Clips: bob (3.2 s), spin (4.0 s). Rigid node animation only: named nodes with translation, rotation and scale clips, no skinned rig and no skeleton. No collision volumes and no navigation data. Opaque materials throughout; the pack uses no alpha blending and no transmission.
