Limited support
This feature is only present in Portal 2: Community Edition. Meta Keys
Warning:
Meta level keys are unique to P2:CE's menu implementation. Changing the UI scripts will lose what these keys provide, unless they are reimplemented. See P2:CE's Panorama code to see how these meta keys are implemented, and see the Technical Details page for more information.
Meta keys are additional properties that change the design and branding of the interface for your campaign.
All art assets must reside in the .assets subfolder in the respective addon. The game will not find the art assets if they are in another location.
