🗑️ Lived-In

A filthy room in one click. Rubbish heaps, food and mould, grimy walls and flies, on any interior. Nothing floats, nothing clips, and Clean Up gives your room back.

Open your room, click Make It Lived-In, and a few seconds later it looks like somebody has lived there for a year without opening a window. Lived-In finds the desks, shelves, seats, beds and floor in your scene by itself and fills them the way real mess builds up: piles in the corners, along the walls and under the desk, food where people eat, flies where it smells.

The problem

Horror games, abandoned flats, student rooms, crime scenes: they all need mess, and mess is the most tedious thing to make. Placing hundreds of cans by hand takes hours and still looks staged. Scattering with particles or Geometry Nodes puts trash on the walls, the ceiling and inside the furniture. A dirt texture repeats the same stain every two metres.

How it works

1. Open your room. Any interior, any materials. Nothing to set up, no UVs needed.
2. Pick the mess: Tidy, Lived-In, Messy or Disaster, or drag the Mess Level slider.
3. Click Make It Lived-In. Don't like the layout? Re-roll for another week in the same room.

What you get

• Rubbish heaps: thousands of pieces (dirty crumpled paper, torn scraps, receipts, chip bags, wrappers, crushed cans, bottles, cups, bottle caps, plastic bags) piling up in corners, along the walls, around the bed and under the desk. Heaps never rise above the space available: there is only a thin layer under the bed.
• Food & mould: greasy pizza boxes (closed, or open with leftover crusts), plates with dried sauce, cereal bowls, noodle cartons (some tipped over and spilling), mouldy mugs, dried coffee rings and crumbs.
• Desk & shelf clutter: piles of paper, sticky notes, book stacks and open books, mugs, cans, pens and pencils. Books stand in rows on the shelves, and the last one leans on its neighbour.
• Dirty walls & floor: dirt rising from the floor, drip streaks, water-stain tide marks, greasy smudges, black mould in the corners and sticky spills, layered on top of your materials.
• Flies: swarms buzzing over the heaps and the desk that really fly when you play the animation, plus some sitting on the rubbish.

Nothing floats, nothing clips

• Every object sits on a real surface it found by ray-casting your scene, never half off an edge.
• Nothing goes where it doesn't fit: not under a low shelf, not inside a monitor stand, a keyboard or a wall.
• Solid things never overlap. Paper piles up, and mugs and pens sit on top of the paper at the right height.

Measured, not promised

• Showcase bedroom (about 30 objects): 9 s on Lived-In, 11 s on Disaster, scan included (laptop, RTX 3060).
• Clean Up: every Lived-In object, collection and material layer removed, your materials restored exactly (checked by an automatic clean-profile install test).

Safe with your scenes

• Everything Lived-In adds lives in one Lived-In collection, sorted into Papers, Books, Food, Rubbish and so on.
• Your shader is never replaced: the grime is mixed on top of it.
• Full undo, and the result is saved in your .blend.

Where to find it

3D View > Sidebar (N) > one99addons tab > Lived-In.

Good to know

• Built for interiors in real-world size (metres). Very large or very small scenes give odd proportions.
• Lived-In scans every visible mesh. Tick Only Selected to limit it to the objects you select.
• Flat furniture made of a single plane (no thickness) hides what is under it from the scan.
• The grime goes on the materials of the scanned objects, so a material shared with objects elsewhere gets dirty there too.
• Works in Cycles and EEVEE. It looks best in Cycles.

Install
