Materials and paint

Painting changes what a surface is made of. The same brush works on architecture — walls, floors, ceilings, stairs, columns, fences, doors, and windows — and on items, so you can recolor a sofa the same way you retile a bathroom floor.

​

Entering paint mode

Three ways in:

• Open the Build tab in the sidebar and select Painting.
• Press P. If something is selected, its current material is picked up as your brush — handy for reusing a finish you’ve already applied.
• Search for Material Paint in the command palette.

Press V (or Esc) to return to the select tool. Every paint action is undoable with Cmd/Ctrl + Z.

​

The material catalog

The paint panel groups materials into category tabs: Selecting a category loads its first material as your brush right away, so you can start clicking surfaces immediately. If the catalog doesn’t have your exact finish, the New material tile at the front of the grid jumps to Material Studio, where AI generates one from a text prompt or a photo — your generated materials then live in the catalog’s Mine tab, and community-shared ones in Community.

​

Painting a surface

Pick a material, then click any surface in the scene. The helper chip walks you through it: Select a material to paint, then Hover a surface to paint. Surfaces are painted individually, so you have real control:

• Walls have separate Interior and Exterior faces — paint the inside of a room without touching the facade.
• Floors split into Top and Sides.
• Ceilings are a single surface.
• Stairs split into Treads, Body, and Railing.
• Items are painted per part — click a chair’s seat to recolor just the seat.

​

Paint scope

By default one click paints one surface — the chip names the part you’re hovering. Press Shift while hovering to cycle through wider scopes (each surface offers the ones that make sense for it):

• Whole object — every surface of the hovered element or item at once (shown as Whole wall, Whole shelf, and so on).
• All matching — the same part on every copy of that item in the scene. Repaint all twelve dining chairs in one click.
• Room — for walls and floors: every wall and floor surface bounding the room under the cursor.

​

Erasing and resetting

• Erase — toggle the eraser at the top of the paint panel, then click a painted surface to return it to its default material.
• Reset all — with an element selected, strips every applied material from it in one go.

​

Custom materials

Below the catalog, the Scene materials section holds materials you create for this scene. Click Add material (+) to make one, then tune it:

• Color — a free color picker with a hex value field, so you’re not limited to the 45 presets.
• Roughness, Metalness, Opacity — sliders from matte plaster to polished mirror to tinted glass.
• Side — render the material on the Front, Back, or Double (both) sides of a surface.

Each scene material shows how many parts use it (Used by 3 parts), can be renamed inline, and has Paint with (load it as your brush), Duplicate, and Delete actions. Editing a scene material updates every surface painted with it.
