@meyti3ds and @CreativeVilla Check post and Epic’s livestream video where the subject was largely discussed. Mainly the point on iconic buildings, even thou some of them are in public domain, others are still attached to local laws (ie: the billboard with Hollywood logo at LA can’t be reproduced without a license from the City Adm) while others that are touristic attractions my also fill in prohibited reproduction in any form without written permission.
