Background Editor

The Background Editor changes the shared 1920×1080 texture used on the home screen and in many menu screens. This is different from the custom application background configured on the Configuration page.

Background Editor

Replace the background

  1. Choose a PNG or JPEG with Select, or drag it onto the page.
  2. Choose Replace.

The source is resized to exactly 1920×1080 with high-quality resampling. Use a 16:9 source to avoid distortion. The Current preview refreshes after replacement.

Extract and restore

  • Extract saves the current texture under images.
  • Restore writes the saved automatic backup back to the shared Unity data file.

Enable backups before the first replacement. Background uses one special backup file rather than a type-specific bundle backup.

Important limitation

The background is stored in masterduel_Data\data.unity3d. Master Duel updates and other mods that replace this file can remove the background change, along with Card Face or Card Icon changes stored in the same file.
