Documents caches

Some documents generate cache files when they're saved. For instance, Atlases and Cities are creating caches when saved. These documents caches are helpful to speed-up the loading of the document when it gets used in a scene. Documents caches are stored in a .red proprietary file format and are located under the "Cache" folder of the working directory structure.

Document caches load much faster than the document data they represent. They take some disk space too ;)

Some rules about documents caches:

• Documents caches are saved when right clicking on the item and clicking 'Save Cache'. Atlases don't follow that rule, and atlas caches are automatically saved after generation.
• A cache can be manually cleaned up from the cache folder (just search for the document name file plus the .red suffix and delete it) or all documents caches can be deleted using the "Clear cache" command from the file menu.
• Documents caches can be exported with scenes that are packed as archives for sharing.
