ALL the notes in the first post:
A point to note – when first installed there is only one terrain background design for all the named backgrounds types (green baize).
And
There are now a few Terrain and Face backgrounds to choose from. The original green baize remains the default with a new Face background to match the Life Points black gradient one, but you now have plain colored, mana symbol, and modern card backgrounds to play with which restore the ‘Your Territory Background’ function. See pic.
If you want to change the terrain backgrounds, look inside the '\DuelArt\Terrain Backgrounds' folder and you'll find four folders named:
Colored (Card Backgrounds)
Colored (Mana Symbols)
Colored (Plain)
Green Baize (Default)
Copy all the files from one of these folders into the games '\Program\DuelArt' folder and allow them to overwrite the existing default files.
You can do the same with the phase strips and the face backgrounds. And in the '\CardArt\Card Templates' folder you'll find a choice between the old style card backgrounds and the default installed modern styled backgrounds.
