Building Designer and Inspect

Two tools change a building after it is placed. The Building Designer changes the whole building. Inspect changes one cell at a time.

Building Designer

Press Building Designer on the toolbar and select a placed building. The pencil on a catalog tile does both steps at once.

Building settings

• Piece set picks the set of walls, windows and doors the building draws from.
• Color theme pins a theme. The swatches under it show the tones the building bakes with.
• Roof picks the set's own roof, Gable or Shed.
• Stories, Seed, Slab color, Rooftop units and the other rows each have an inline explainer.
• Randomize rolls a new seed and theme as one undo step.

Materials and colors

The designer lists the surfaces the building is made of, biggest first. Give each one a material and a color. You can pick Roblox's own materials or any MaterialVariant installed in the place. The choices survive re-bakes and travel with a style. Reset all materials and colors goes back to the set's look.

Styles

What you change is saved as a style. The plugin's own entries never change, so your first edit saves a copy, and later edits go into that copy.

The Style section renames, copies and deletes styles. Turn off Save my edits to the style for a building that should change alone.

A style shows up in three places: on its entry's shelf in the City Builder dock, in the polygon building's Style list, and in the city bundle editor. Styles are stored in the place under ServerStorage.CityBuilderStyles.

Your own pieces

1. Load a building and press Create my piece set. The plugin copies the building's pieces into the place.
2. Select a model or part in Studio and load it into a slot under Model slots.
3. Every building on that set re-bakes when its pieces change.

Duplicate with a new seed places a copy with a fresh seed, which is the fast way to grow a row of similar houses.

Inspect

Pick the Inspect tile, or press Inspect Buildings on the toolbar, and press Start inspecting.

Hover a placed building and rest the mouse on a cell. A card opens that names the piece in that cell, and the highlight follows the wall. Change the piece from the card, for example a window for a door.

Buildings placed before cell editing existed need a refresh first. Load the building in the designer and press Update building generator.

Generator code

Generator code, under Advanced settings, picks where buildings get the code that bakes them.

Option	What it means
In the plugin	The default. No code is stored in the place. Without the plugin, buildings keep their geometry but stop re-baking.
Copy in ServerStorage, Copy in ReplicatedStorage	One shared CityBuilderGenerators folder. Buildings re-bake without the plugin and in a running game.

Move existing buildings moves every building in the place onto the option you picked.
