FAQ
What size should a UEFN island thumbnail be?
Epic requires rectangular island thumbnails to be at least 1920×1080 in a 16:9 aspect ratio and no larger than 5 MB. That is the base size we export.
Can I match my island's look?
Upload a screenshot of your island as a style reference; we extract the palette and condition the generation on it.
