It's done, you can start LDD ! (^_^)V
Now you have access to more than 200 additional parts coming from Lego Universe.
And you can customize LDD.
How to add new Custom Decals ?
Be careful, a lot of parts don't have UV mapping (texture coordinate), then it's not possible to add custom decals.
I think it is better to be confined to parts already defined in the file DecorationMapping.xml.
And it is best to follow the surfaces accepting decals.
First, close LDD.
Make your decal with transparent color in background, then resize it to 128*128 (unlock Picture's aspect ratio)
Copy it in the Decorations directory and give it a filename with 5 digits (mine start at 90000.png)
Get the part number for the part you want to add a custom decal.
Edit the file DecorationMapping.xml in the Definition directory, add a new line at the end of file
Example: use 90001.png with part 3814 (minifig's torso) on the surface 1
<Mapping decorationID="90001" designID="3814" surfaceID="1"/>
You can start LDD.
if you make a mistake by not complying with the instructions, LDD could crash.
How to remove my files ?
Close LDD, then delete the directory db
For Windows 7 and Vista it can be found here C:\Users\UserName\AppData\Roaming\LEGO Company\LEGO Digital Designer\
For Windows XP here: C:\Documents And Settings\UserName\ApplicationData\Lego Company\Lego Digital Designer\
Delete the directory Definitions
For Windows 7 and Vista it can be found here C:\Program Files (x86)\LEGO Company\LEGO Digital Designer\Assets
For Windows XP here: C:\Program Files\LEGO Company\LEGO Digital Designer\Assets
Start LDD.
You don't have to reconstruct the lif files, LDD use directories with the same name if it find them.
