Interior AI adds custom wallpaper to editable rooms

• Custom wallpaper uploads can now be applied inside Interior AI's editable rooms, as the new demo shows.
• The Render button turns the current 3D viewpoint into a photorealistic still in about 20 seconds, according to the announcement.
• The editor is already live in Interior AI, which the developer confirmed in a follow-up.

Custom wallpaper is the standout in the latest demo: an uploaded texture can cover an object as well as a wall. The developer has already removed Blender from a feature that Interior AI now advertises as a phone-video-to-3D workflow.

Interior AI developer Pieter Levels said getting an image model to place a supplied wallpaper correctly had been difficult. The new editor applies the uploaded texture to a chosen surface in the room's 3D model.

Individual object materials are editable too, as Levels demonstrated in the wallpaper thread.

Levels described four years of photo-in, redesign-out operation when introducing the feature. The existing photo workflow takes a room image and a selected style, then generates redesigned stills.

His early 3D experiments also accepted photos and floor plans as inputs, according to the announcement thread. For walkthrough uploads, Levels said in a reply that video was sufficient without LiDAR.

In an early working demo, users could:

• Empty the room completely.
• Move furniture.
• Remove individual furniture items.
• Repaint walls, floors, ceilings and objects.

The subsequent launch supported walkthrough videos of a living room or an entire floor, with the result becoming a walkable, editable space.

Hovering over the Style menu previews presets directly in 3D, as Levels demonstrated in a later update. Rendering is a separate step: the selected camera perspective becomes a photorealistic image, with a claimed wait of about 20 seconds.

The editor now includes a top-down floor-plan view alongside its navigable room view. When announcing it, Levels floated a formal floor-plan export as a possible later addition.

The first release used a custom headless Blender build running on a VPS. Three.js already handled the viewer, which Levels clarified in an early reply.

He subsequently removed Blender, describing the implementation as “just @threejs.”

There was also a realism-versus-editability tradeoff in his experiments: Levels said he had tried baking, but then could no longer move objects.

Levels's next proposed experiment is to feed a walkthrough of the edited 3D room into a video model such as Seedance, aiming for a fully photorealistic video of the redesign.
