Progress Bar Pack is an effort to make a comprehensive suite for creating progress bars of all kinds - so if there’s something relevant you think is missing from the pack, please tell me and I’ll see what I can do about it.

The pack contains shaders, scripts and textures for displaying your linear data, such as health, mana, level progress or loading.
Check out the web demo to see what kind of effects are available at the moment. The documentation is also available online.
The progress bars can be drawn on objects on ortographic or perspective cameras, or on OnGUI (only linear progress bars supported for OnGUI atm). A script package is included to make integrating progress bars to your project as straightforward as possible, as well as a 19-page manual.
Hope people find this useful. I welcome all feedback, especially on how to make this package more comprehensive, easier to use and just generally better.
