In regards to the complaints on video quality - it appears it’s only one of the videos that have really bad quality - “Designing the City Foundations”. The other videos have fine quality.
Also @indystry, I’m currently at the foliage tool section of the tutorial, and there doesn’t seem to be an ‘actor foliage’, only a ‘static mesh foliage’ type available (in version 5.3). What should I do to make this work?
Edit - figured it out. Had to make a new ‘basic’ level, as I’d made an ‘open world’ level which enables World Partition, which doesn’t allow Actor Foliage.
