I'm wishing really hard that this will get me somewhere...here goes!
The guild cloak emblems and the trim patterns are available in the local DDS and VPK files. It's easy to get to them, extract them, and manipulate them for various projects.
One thing that's not accessible are the cloak pattern images, and it would be awesome if they were made available.
(I'm building an EQ2 fansite that will feature a guild cloak heraldry database, and being able to utilize the pattern images along with the emblems and trim would make my life a lot easier.)
I can also see that being able to extract and use the patterns would come in handy in making guild website graphics and guild standard signatures...lots of guilds are so proud of their heraldry and want the imagery displayed everywhere possible.
