How to Use the Skins numbered (02), (03) and (04)
The vanilla game and most user created scenarios will use only skins (01) and (02). Higher numbered skins will not show by default. If you want to add the higher numbered skins to a [holland] scenario, such as any of the Market Garden scenarios, you need to load the scenario into the Scenario Editor, select the building you want to reskin, and cycle through the skin options with SHIFT-LEFT CLICK.
