Installation

In Blender open Edit, Preferences, Get Extensions, then use Install from Disk and pick the victorian_mansion_generator zip.

Usage

1. Open the Victorian tab in the 3D viewport sidebar (N). With nothing selected, click the picture to choose one of the nine styles and press Add Mansion, or use Shift+A, Mesh, Victorian Mansion. Surprise Me adds a random mansion.
2. With the mansion selected, the first page holds the main choices: style, size and floors, colours and condition, tower, roof, porch and windows. Click a picture to open its gallery, or step through the options with the arrows.
3. The sub-panels below hold every other setting: Massing, Roof, Walls, Windows & Doors, Porch, Gingerbread, Interior, Grounds and Custom Colours.
4. Shape changes rebuild the outside at once; the rooms, furniture and yard follow a moment later.
5. Mansion tools: Rebuild, Convert to Plain Meshes (for editing or export) and Delete Mansion.

Detail Low builds fastest while you design; switch to High for the final render.
