Apart from the global illumination I appreciate the realism of the shadows cast by the light sources. Namely the shadow cast by the person itself is much sharper than the shadow cast by the bars of the "cage" in which the light is located. This is exactly what you would see in real life. Objects closer to the ground have sharper shadows than objects closer to the light.

Большое спасибо, я крайне рад что вам понравилось. Всю написанное далее исключетельная шизофазия человека со справкой: Команда на самом деле была в шоке, когда увидела результат. Потому, что это разрабатывалось не итеративно, и видеть промежуточные стадии не получалось. В итоге, только после полного закрытия всей разработки графического конвейра и полной отладки(ибо из-за того, что он комплексный, нужно было чтоб все стадии конвейера работали без ошибок и ломалась эта дрянь на каждом шагу) Только когда была исправлена последняя ошибка и первый билд показал количество фэпэсов... я не знаю как это описать, но закончили это ночью между около 1:30 одно из европейских подразделений Epic, короче, ни кто не ушёл домой после билда, некоторых даже разбудили и они сами после такой новости подтянулись, юнит-тесты гонялись до 10:30 утра пока лид не задокументировал, что ядро технологии рабочее и это надо пускать в производство, всю команду принудительно отправили домой отсыпаться. Это наверное первый случай в истории компании, да и наверное всех 3A компаний, когда менее, чем за 12 часов было принято такое колоссальное и далекоидущее решение о движении всего подразделения разработки. Первый кто об этом узнал был сам Тим Суини, не все знают, но он сам является разработчиком и прекрасно понимает как работает движок, он лично принимает по нему решения и иногда даже пишет модули, надо ли говорить, что парень который сделал билд и глава компании разговаривали лично по телефону так как будто это настолько знакомые товарищи, что было ментальное ощущение, как будто они оба в трусах на диване с кружкой пива и пока один поправляет вывалившееся яйцо, другой пытаясь вытереть пролившееся на белый ковёр пиво, только сильнее втирает и размазывает его. Разговор по содержанию только добавлял атмосферы: И что прям каждая стадия конвейера запустилась? - Каждая. Ничего не забыли? - Ничего. Может что-то отключено? - Нет, точно нет. Defin'ы проверили? - Проверили, профилировщик показывает, что всё включено. И сколько говоришь фэпэсов ? - "людк, ты щас умрёшь" А полигонов? - там ваапще такое... И помните, я всего лишь абсолютно случайны психический нездоровый человек со справкой в комментариях.

Lumen is designed for realtime GI and reflections, not for offline rendering or only high-end specs... There have to be cut corners. Also Lumen reflections aren't meant for mirror like surfaces and software version won't be by devs words. Hardware acceleration will come though, they said it during one of the official livestreams, so hopefully we will get triangle-based intersection reflections.

foliage is too hard for Nanite teck and it's not recommended for using it with Nanite, u may lost a lot of perfonce just enable Nanite on grass.

From the perspective of game developers, using resources and time to make your game compatible with features that are trapped on some cards of a single manufacturer that isn't even the same of consoles and doesn't even perform that great on the bulk of the cards that have said feature is a real time waster. For Nvidia, neither this nor AMD's announcement are great news, they invested a lot of cash on this technology.
