Doomsday 2 manages resources as assets. In practice, an asset is comprised of Doomsday Script and a set of associated files inside a package.

Before you start working with assets, you should have a good understanding of how packages work in Doomsday 2.

• Relative file paths. When an asset refers to a file, the path is relative to the ScriptedInfo file where the path is specified.
• Low-level image filtering

• Resource packaging guidelines
