Walkable demo
Office lobby
Walk a 35 by 26 metre corporate ground floor from the Office Lobby and Building Facilities pack: eight speedgates, a curved reception run, five lift landings, an escalator and stair, a visitor lounge, vending and parcel lockers, a staff canteen and a corridor to the washroom.
About
One ground floor from 48 of the pack's 111 models, in the room preset with daylight and lamps under a 4.5 m ceiling of acoustic rafts.
You arrive on the entrance matwell between planters and banner frames, facing the curved reception desk with its side modules, panelled back wall, belt lane and sign-in kiosk, with a planter island on the concourse. To your left eight speedgate pairs and a tripod turnstile close the west side, with planter troughs continuing the line; beyond them are the escalator and stair, the staff canteen with two kitchenette runs, six seat tables, soft booths, high tables and lockers, and a lift lobby with five landing doors on the 1.2 m wall grid, one standing open onto a lift car. To your right is the visitor lounge of sofas, armchairs and coffee tables behind planter troughs, and along the east wall the drinks and snack vending, coffee point, recycling banks and four parcel locker banks. A lit corridor leaves the north wall between reception and the lounge: its left door opens onto the pack's fitted washroom scene, its right door onto the comms and server room scene, and a fire door closes the end.
This pack ships animation clips: the speedgates, turnstile, lift doors, corridor and fire doors, vending machines, parcel lockers, staff lockers and the kitchenette doors and drawers play as you come within three metres and rewind when you leave. The escalator handrail and steps are static geometry, and the upper floor it rises to is scenery: the walk stays on the ground floor.
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.
