How To Create Rainlendar Skins
According to the Rainlendar FAQ:
The skin documentation and tutorials are not ready yet so probably the easiest way is to take the Shadow4 skin that comes with Rainlendar and start modifying that. Rainlendar2 skins (.r2skin) are just normal zip archives with different file extensions. The archive contains few xml files and the resources (images, scripts, …). The skin.xml file must be in the root of the archive so make sure that when you are zipping the archive after modifications that it doesn’t contain any extra folders.
During skin development you can also just unzip the archive into Rainlendar’s skins-folder. This way you don’t have to zip it again after each change.
