This need to be part of official Unreal documentation. Thank you!

@n1lknarf Месяц назад

Epic games sell the support: that's why the documentation is bare bones.

@greyly_ 3 года назад

I'm currently slogging my way through many hours of Epic's training videos and it's very refreshing to watch something like this which has actual effort put into it. Not to mention editing.

@Beriol9 3 года назад

I've probably seen thousands of tutorials about anything in the past 10 years. However, I've rarely seen this level of quality in any of them. Top notch, really outstanding! Thanks a lot for this!

@ChinyONE 3 года назад

This level of perfecion is unmatched. U could easily make a good amount of money with this level of quality :D. Super nice to put this up for free. THY SIR!

@WOLFPACKED 2 года назад

agreed this is higher grade content and presentation then a lot of tutorials on udemy

Best overview of Unreal replication on the internet.

Alex your content is SO GOOD, you have to apply for an Epic grant or something.

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

@Docthunda 2 года назад

Same Im so lost. Its clearly explained but still confusing

@LevySkulk 2 года назад

@@Docthunda I still come back to this video 9 months later lol. At this point I've made my own C++ steam multiplayer solution with blueprint integration, but still need a refresher at times. Know it's been 6 months, but if you have any questions I can try to help.

Best video on Multiplayer in Unreal Engine. Amazing animations + diagrams and love the fact that you show the c++ part as well and not just BPs.

Oh man after more then 2 years of trying to understand UE4 multiplayer i finally found your video. 10/10

@ThatGuyCanCode Год назад

I am extremley proud of how much information you could fit in 25 minutes and how easy it was to follow. Impressive job!

@spades10 3 года назад

These videos are great training tools for our designers, scripters and QA to know about inner workings of the engine at least at the surface level. Plus great refreshes, will definitely check more videos from you in the future :)

@Unknown King talking as if people can't learn from anything besides documentation

@Dazza_Doo 2 года назад

@Unknown King The Documentation is fragmented and only serves as a rough guide. Here I have the nugget of info that comes from Live Streams, Engine Code that you can't find in the Docs

@Technokarate 3 года назад

25 Minutes? Damn! I've been at it over an hour taking notes as well as going back and making sure to understand everything. Pretty good, I see that multiplayer is C++ mandatory. I finally have a reason to dive into it!~ 3 years later. 😝

@aaronh560 2 года назад

Great video, excellent production and information and nice to see C++ and Blueprint explanations I'm starting to learn multiplayer so I'm at a stage where I don't really know what I need to know so this has a lot of info in one place I can re-watch.

@mordofable Год назад

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.

@QuackTeamJames 3 года назад

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.

Awesome video, thank you very much for it! There aren't many resources out there where stuff is actually explained, so with these videos you are filling a very important gap. By the way, it is plain to see that a ton of effort has gone into these videos, huge props for that as well! Can you tell me what software infrastructure do you use to make these?
