  • Extremely useful video. So hard to find videos that are willing to break down some of these design philosophies and de-mystify documentation. After watching a few times, I feel confident diving into the documentation myself. Edit: Two weeks later and I'm watching this video for the 4th time. Edit: It's been 7 months and I'm back. This shit's deceptively simple to understand but quite hard to put into practice. Edit: 9 months and I still come back to this video sometimes. At first i was coming to learn how to to this with Blueprints and advanced sessions, but now I'm here for C++ and workflow lol

  • so many positive comments here - normally I'd just upvote.. but this video deserves every individual comment of praise it's got! So much incredible information packed in here, and yet there's very little nonsense. just succinct, clear, well done explanations. Also the depth that is introduced along-side the higher level concepts is a really well done balance. 💯 Can't say enough good things - compared to most other documentation and tutorials/videos, this sits at the top.

  • Thanks for this Alex, this kind of general understanding should be given more precedence in computer science generally. At least as far as my prior attended lectures, only focusing on the individual components and never taking an overview or talking about 'basically what you're looking at is authority or no authority' really helps clarify understanding.
