About
A deliberately generic low-poly kit of working mechanisms. Every model ships at least one glTF animation clip driving named nodes whose pivots sit on the real hinge, axle or slide axis, so a developer can drop a door, a lift, a conveyor or a trap into a prototype and see it move. Looping clips are named idle, spin, bob and flicker; one shot clips are open, close, fire and trigger. Eight doors and gates share a 3 m wall bay with left and right connectors so they tile into a continuous wall. Metres, +Y up, +Z forward, all models resting on y=0, eight shared materials. Node TRS animation only; there is no skinned rig, skeleton, collision or navigation data in these files.
