Standing mech

A 10 m bipedal repair-bay mech in navy armour with warm white plates and safety-yellow trims, standing on two toed feet. It plays a looping scan idle: the waist and head sweep the bay, the arms swing at shoulder and elbow, and the shoulder missile pod lifts on its hinge.

How it was made

The brief given to 1DesignTool's “3D object” template:

Standing mech for the Mech Hangar kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. It moves: author a seamless baked loop (2–12 s) with every pivot exactly at its hinge, axle or swivel, and keep the base still. This is one part of the Mech Hangar kit (Low-poly style, flat-lowpoly direction): A bay where giant robots are repaired. Use ONLY the kit palette, by name: steel grey #757e8a, safety yellow #ffdd33, navy #1c2a54, red #c32222, steel grey dark #525860, safety yellow dark #e6bf00, steel grey light #a3a5a8, safety yellow light #ffea80, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `mechColourAndLoadout` (0–1, default 0.5) for the kit's "Mech colour and loadout" setting wherever it makes sense on this part, and keep that id.

Note: Default size is about 5.7 m wide (pauldron to pauldron), 4.1 m deep (toe claws to exhaust stacks) and 10.32 m tall to the antenna tip (head top about 9.7 m), the same scale as the kit's repair-bay mech. Origin is at the bottom centre, the soles rest on y = 0 and the mech faces +Z. 2,656 triangles, flat-shaded, no textures. Every material is named after the kit palette colour it uses. The exporter clones one material per mesh, so the same name (for example 'navy') appears on several GLB materials, so recolour by material name, not by index. The GLB carries one seamless 8 s rigid-transform clip ('scene-motion'). Each moving node sits on its joint: the torso yaws on the waist ring, the head yaws on the neck collar, the arms pitch at the shoulder drums, the forearms pitch at the elbow drums and the weapon pitches on its hinge pin. The feet, legs and pelvis never move. mechColourAndLoadout sets the armour colour and the shoulder loadout: warm white armour with navy panels and a floodlight below 0.33, navy armour with warm white panels and a 4-tube missile pod up to 0.66 (default), red armour with a yellow visor and twin cannons above that. legLength and stanceWidth reshape the legs, and everything above the knees rides up or down with the shins. scanAmount scales the loop amplitude and is baked into the GLB at its default (1), so changing it only affects the viewer until you re-export. Each part has an outer node with the library id (mech-hangar-standing-mech.*), which is the animated joint, and an inner '<part>-meshes' node with the hyphen-free id the kit's plan validator needs (mechhangarstandingmech.*). glb-lint reports 0 errors and 4 heuristic warnings, all expected: per-mesh material clones exceeding the direction's material count, duplicate material parameters caused by the same clones, deliberately nested or embedded joint boxes, and a 10 m height against the direction's 1 m reference.
