# Before you buy

## What you need

- **Blender 4.2 to 5.2** (both the extension and legacy zips are included).

- **Unreal Engine 5** for the live link, with the free *Python Editor Script Plugin* turned on.

  The link is optional: the pieces work in Blender on their own, and you can export them like any model.

## What you get

- **Full:** 114 pieces in 8 categories (Calibration, Building, Metrics, Props, Loot Containers, Pickups, Weapons, Creatures).

- **Building Pack:** Calibration + all Building pieces.

- **Props Pack:** Calibration + all Props.

- Every version includes the Blockout Wheel and Browser (Shift Q), size settings, style presets, themes and the Unreal link.

- Free updates for the version you bought. Upgrade from a pack to Full and pay only the difference.

## How it works, in short

1. Install the zip in Blender (Edit → Preferences → Add-ons → Install from Disk).

2. Set your sizes: character height, tile size, doors, windows…

3. Press **Shift Q**, pick a piece, click to place it.

4. Press **Send**: it appears in Unreal with collision, sockets and a 1 m checker material.

## Good to know

- Every piece follows fixed rules for origins, sockets and collision, so it snaps together and works in Blueprints.

- Unreal setup takes a minute: copy 2 small files into your project's `Content/Python` folder.

- A full user guide (install, Unreal setup, every category's rules, troubleshooting) comes inside the add-on.
