The server as a Resource Pack Addon to help display new blocks and items. New blocks are displayed only by using the Addon, however if you which to see the items and armors you will need to install either MCPatcher or Optifine in your client.
We recommend Optifine as it will help you have more control over the Video Settings.
There are a few addon versions, more will be added has they are made, however, if you make one that you would like to share, please leave a comment on this page with the link to it.
Faithful Based [Download]
The default addon is based on Faithful, but it will work good with the vanilla pack. Note that this may be a bit strange when using with Visual Armors and the Vanilla Pack, as the Faithful armors have bigger resolution.
