Please provide a little more detail as to what you are after in the tutorial Dave? This could mean a couple of different things currently.
What do I need to do when I want to make a new region with assets that are not in any built in region. For example I want to see assets like<kuid2:254127:28183:1> Sentinel steam tractor or the <kuid2:84912:29673:1> Steam Lorry Sentinel DG4P Castrol or even the <kuid2:201734:99000056:1> Steam road train loco driving up and down the roads.
