Walkable demo
Mech hangar
Walk a 32 by 24 metre hangar built from the Mech Robots and Battle Hangar pack: three maintenance cradles holding an assault frame, a line frame and a quad walker built from parts, a gantry along the back, parts racks, a forklift and the doors.
About
One hangar from 24 of the pack's 112 models, on the pack's own 4 m floor tiles with hangar wall segments around it, in the hall preset with cool light, window strips and strip lights under an 8 m ceiling.
You spawn by the roller door and the blast door facing three service bays. Each bay is a maintenance cradle with a diagnostic console in front and a frame inside, assembled from the pack's parts: an assault frame with a wedge head and assault arms, a line frame with a twin-optic head and line arms, and a quad walker with a dome radar head and autocannon arms. A gantry of six sections and a stair runs along the back wall; three parts racks and three spare limb stands line the west wall, with the forklift by the doors and six hangar columns holding the roof.
Nothing moves: this pack ships without animation clips, so the frames stand still in their cradles. Rigging the parts into a single articulated frame is yours to do; each part is a separate model with its own origin.
Every piece here is a published model from the pack, placed by hand. Walk with the keys or touch, and approach a piece to see it move if it has animation. Colliders, navigation and gameplay are yours to add.
Points of interest
Assault frame
Assault legs, torso, an armoured wedge head and two assault arms in a maintenance cradle. Frames are built from parts: legs on the floor, the torso at the leg height, the head at the torso top, arms hung from the shoulders.
Assault Torso (Mech Robots and Battle Hangar)Line frame
A line frame in the middle bay: line legs, line torso, twin-optic head and line arms, with a diagnostic console in front of each bay.
Line Torso (Mech Robots and Battle Hangar)Quad walker
Quad legs and torso with a dome radar head and an autocannon arm each side.
Quad Torso (Mech Robots and Battle Hangar)The gantry
Six gantry-straight sections and a gantry stair make a 24 m walkway along the back wall behind the cradles. Walking stays on the floor; the gantry is scenery.
Gantry Straight (Mech Robots and Battle Hangar)Parts store
Three parts racks and three spare limb stands along the west wall, and the forklift by the doors.
Parts Rack (Mech Robots and Battle Hangar)Doors
A roller door and a blast door in the front wall between hangar wall segments; the hangar columns stand 6 m tall under an 8 m ceiling.
