Areas where compatibility with PF or the existing EE client is lacking, or requires additional steps.
Some assets will not work directly and require additional configuration. For example, clothing in the official client comes with a script that defines things such as the mesh shape to use (robed, normal etc). Where possible I will replace these with text config files.
Some of these images are indexed PNG, some are true-color. The true-colors ones currently do not work properly. So, it's easiest just to convert them to indexed.
