  • BackgroundImageMovementMode:
    • Static (Screen Space)
    • Follow Graph (Tiled)

6) Notes on Background Movement

The plugin exposes practical movement modes available via editor style settings:

  • Static mode for non-tiled screen-space presentation
  • Follow Graph (Tiled) mode for tiled background behavior

7) Troubleshooting

Theme does not visibly change:

  • Ensure plugin is enabled.
  • Switch to another preset and back.
  • Re-open a Blueprint graph tab.

Background image does not appear:

  • Verify file path exists and extension is supported.
  • Try png or jpg first.
  • Ensure bUseCustomBackgroundImage is enabled.

Grid lines still visible over image:

  • Enable bHideGridWhenUsingCustomBackground.

Returning to Default does not match your expected custom setup:

  • Default restores baseline editor style captured by plugin at startup.
