thumbnail

Saves List

A path to an asset in the addons .assets folder. This thumbnail is not only used in the chapter selector but also appears as a background in the save menu. If no image is specified, a fallback will be used.

Recommended Size: 1920x1080 (or aspect ratio equivalent)

This image will be sized to fit for chapter selection entries. However, in the saves menu, this image will be sized to cover a region of the save button, so some parts of the thumbnail will be cropped.
