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.
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!
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
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!
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
@Dauron Robinson 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.
Wow, you have the most well explained Unreal Engine videos I have come across. Thank you so much for this and for sharing your knowledge and understanding!
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 :)
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.
Muchisimas gracias por el video, me ha ayudado bastante a entender los conceptos multijugador, me lo tendre que ver una o dos veces mas para que se me quede bien grabado en mi cerebro.
Thanks for this. I appreciate the high information bandwidth; it was great to hear someone speaking with the voice of an experienced developer, rather than the endless newbie UE4 videos that are so prevalent on youtube.
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.
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?
i Honestly LOVED your video about the topic. i cannot be thankful enough for your video and how informative it is. wish you the best in your future videos!
awesome video! I've been building my own 2v2 PvP game in UE4 for the last few years and I've started to really start digging into Replication - I picked up some things I didn't know about here!
This is an awesome channel, can you go over the character movement system next? Edit: it seems like they're going to be changing it with the prediction plugin/system, so a new movement system is coming too, maybe cover that when it drops?
Great video love it. This video strengthen my foundation even further. But I have some personal comment on the Server check u mentioned. I personally prefer to use IsNetMode(NM_Client) Check instead of HasAuthorithy. Because sometimes having authorithy doesn't mean you are server.
By any chance, do you have a a paid tutorials somewhere for this? And if not, have you considered to creating some? I would pay :D The level of quality and explanation is above anything else I have came across so far.
very interesting! seems this is the centralised architecture (server-client mode), are there any games using distributed consensus such as RAFT, BFT for synchronisation?
I would like a course from you on Multiplayer. Start to end development, packaging and deployment it on server. Who wouldn't like that with the amount of details he's capturing.
Awesome .. still trying to wrap my head around all this info .. If you're up for a suggestion .. I'd suggest you add SideFX Houdini to your list of educational videos
But skins should be replicated, because other players can see them too. Stuff like HUD color or crosshair, depends if you want spectators see your HUD and crosshair, or if you'd like to see that in recorded demo.
can you please create an explanatory example of these slides, like you made tutorial for creating project from scratch. multiplayer replication theory is very good, and thoroughly explained, but a working example would help us a lot. thanks i like the way you explain, whenever i have to start a new project i watch your new project from scratch video. if you make Multiplayer video on sublime , that would be super great.
This video may win the award for most informative (and best produced for teaching) video of all time. I agree with the top comment -> this *needs* to be a part of the official Unreal documentation. I'm sharing this with everyone.
This was really useful even for someone like me who isn't using Unreal. Fantastic overview of all of the key concepts of how one might architect a multiplayer game, with great visuals and even some short, but useful peeks into the actual code as well.
I have some topic suggestions you might be able to demystify Procedural world. If a world got randomly generated. Whats the correct way to sync data? I'm talking, terrain, floliage, Procedural villages, forests and other gameplay elements. I've seen games using seeds. My best guess that most random numbers aren't random unless you use a specific node and seeds are predictable that is more gives the illusion of random where it's more like millions of predictable possibility?. Though, I guess you would still need to replicate changes to the landscape but I'd imagine sending millions of transforms and object references would be overly pricy? Dedicated Servers. Playing games, I've rented servers to play co-op games with friends. How does one create that option? Do you need to create a separate build of some sort? Or maybe set a dedicated server only launch option somehow? Match Making. When Looking for servers over the internet, rather then joining using an IP. How does that work?. My current guess is that you as the game provider needs a specific match making server which hosts register and clients and get that information? I've come across some API's that do some stuff like PlayFab but I'm still trying to understand the connections between everything Replicating animations. My best guess on this is using a state machine which driver the clients animations and maybe using rep notifys to update other players? Or maybe it's driven client side by the same logic use on client side? UE4's default pawn is automatically replicated so it still seem a bit like magic
Holy f*ck, how did i not know about this video when I was struggling to learn how replication works? :( This video is just great 5/5 content, was PERFECT. Looked for a nice explanation for a dude who wanted help with replication and found this gold.
Hi great video but I have a question and cant figure it out, what if I place an actor in the level and want it to replicate on a dedicated server. The server may not always have a player connected so how do I keep replicating stuff if the actor has no owner?
There's just one thing I haven't figured out yet and couldn't find in this otherwise amazing video either. Is there in blueprints a "_validated" function or does it simply only exist for C++?
@Alex Forsythe Well, if the validate function automatically takes care of the result (ie. kicking the user), the check in the Server RPC in Blueprints unfortunately still won't in the same way. How to compensate for this? I guess this may be simply like one of those things where Epic is waiting for some user to send a pull request to make this feature available in Blueprints too, as so often in the past? Might be possible to implement it in a similar way how RepNotify for Blueprints is?
As far as I can tell, Server RPC validation is a C++-only feature. If you define a Server RPC in Blueprints, you can still check the parameter values and refuse to proceed with your implementation if they're not valid, but Blueprints don't provide a direct equivalent for the WithValidation specifier.
Great video. I didn't understand much because all this is new to me but I enjoyed the video a lot. This is maybe a silly question, but I have to ask. What is the font at 15:41? Looks great to me.
The typeface used for source code is Consolas, which is included with Windows. For most other titles, I use an open source font called Mohave. en.wikipedia.org/wiki/Consolas github.com/tokotype/Mohave-Typefaces
can you make a video about multiplayer racing game ? when the car of player A collide with the car of driver B, how does the system understand the physics?
But right below in the corner of tNice tutorials blue screen, there's "Program" wNice tutorialch most likely states "Aggressive TE" if you click on that you have a
This need to be part of official Unreal documentation. Thank you!

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.
I've rewatched this 10 times over the last few days in order to soak up all the details. This is so valuable thank you!
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
Unknown King talking as if people can't learn from anything besides documentation
Unknown King um.. i do?
Please dont stop with making those valuable videos, this is just pure gold!
Alex your content is SO GOOD, you have to apply for an Epic grant or something.
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!
agreed this is higher grade content and presentation then a lot of tutorials on udemy
I am extremley proud of how much information you could fit in 25 minutes and how easy it was to follow. Impressive job!
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.

Same Im so lost. Its clearly explained but still confusing
This video is excellent. You explain everything so efficiently while remaining incredibly clear and highly detailed.
Best overview of Unreal replication on the internet.
Binge watched all your unreal videos. An excellent detail oriented resource for the community, appreciate it bud.
Dude! You’re videos are bloody brilliant! I learned more in 20 mins than most 5-10 hour video courses. You gotta do one on GameplayAbilitySystem
Alex, this was one of the best breakdowns on ANY technical subject I've witnessed. Do you have a blog or etc. where you share your process?
Probably the clearest explanation on how Unreal Replication works! I wish I saw this sooner !
Amazing explanation and presentation, love how you show blueprint and c++ right next to each other when most tutorials only go over blueprint.
One of the best tutorials I've seen on the topic, thank you for your work!
Wow, you have the most well explained Unreal Engine videos I have come across. Thank you so much for this and for sharing your knowledge and understanding!
Amazing video. Thank you for all the effort put into it!
the level of detail in these guides is mind blowing!
This video gave me the confidence to give a simple turn-based multiplayer game another try.
Oh man after more then 2 years of trying to understand UE4 multiplayer i finally found your video. 10/10
Wow this video was so incredibly helpful! I love how straight to the point it is and the visuals add so much!
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 :)
This was massively helpful, the visuals and explanations were on point.
Thank you.

great as always, thank you for your hard work!

Incredibly detailed content, and fantastic presentation! Outstanding!
Dang man.. I wish you continued this kind of stuff. Epic should hire you to do tutorials
The content and video quality are superb, especially given the difficulty in understanding as tough of a concept as replication. Thanks. Subscribed
This level of content is outstanding. I've never joined a patreon before but I'm going to join yours right now :P
The level of quality of this content is astounding
I'm so glad I found your channel. The quality and info on this video is awesome
very clean presented and super resourceful material. Thank you very much!
This is an awesome channel, can you go over the character movement system next?
Edit: it seems like they're going to be changing it with the prediction plugin/system, so a new movement system is coming too, maybe cover that when it drops?
I'm a couple years late to your video. But I have to say the way you explain things is perfect. Thank you.
This is an AWESOME video. Extremely clear and thorough,many thanks for doing it
Great video love it. This video strengthen my foundation even further.
But I have some personal comment on the Server check u mentioned. I personally prefer to use IsNetMode(NM_Client) Check instead of HasAuthorithy. Because sometimes having authorithy doesn't mean you are server.
Thank you, this was great! Ideas for future videos: something on the Replication Graph plugin would be fantastic
Your videos are great. Looking forward for more.
Could you do at some time a video about prediction keys and scoped windows? Thank you for amazing videos.
By any chance, do you have a a paid tutorials somewhere for this? And if not, have you considered to creating some? I would pay :D The level of quality and explanation is above anything else I have came across so far.
It's really a great find for me, as I'm started working on Unreal. Please do share your knowledge, which is really helpful.
Thanks!

Great video! This helped a newbie out a lot! :)
Wow learnt a lot. Fantastic video - thank you very much!
Great explanation! Thanks for making this.
Really informative, thank you :D
Awesome .. still trying to wrap my head around all this info ..
If you're up for a suggestion .. I'd suggest you add SideFX Houdini to your list of educational videos
But skins should be replicated, because other players can see them too. Stuff like HUD color or crosshair, depends if you want spectators see your HUD and crosshair, or if you'd like to see that in recorded demo.
LET'S GOOOOOOOOOOOO!!!!
Please make more videos! the community need tutorials about replication/multiplayer and AI! (smart objects too!!)
can you please create an explanatory example of these slides, like you made tutorial for creating project from scratch.
multiplayer replication theory is very good, and thoroughly explained, but a working example would help us a lot. thanks
i like the way you explain, whenever i have to start a new project i watch your new project from scratch video.
if you make Multiplayer video on sublime , that would be super great.
This video may win the award for most informative (and best produced for teaching) video of all time.
I agree with the top comment -> this *needs* to be a part of the official Unreal documentation.
I'm sharing this with everyone.
Seldom one to get involved on KZclip comments, but this is pretty excellent. Concise, informative, and well narrated.
could you tell us, what tools did you use to make the video cotent animated, it's amazing, thanks!
This is the best UE tutorial I've watched. Ever.
This is saving me so much time. Thank you.
Best video I've seen on the subject. Thank you so much!
I would pay good money for a full blown Udemy course from you
I feel like this video was better than the live training videos by unreal
This is suprisingly awesome video. Thank you!
This was really useful even for someone like me who isn't using Unreal. Fantastic overview of all of the key concepts of how one might architect a multiplayer game, with great visuals and even some short, but useful peeks into the actual code as well.
This is really good, thank you!
This video is the best I've ever seen in 2021, thank you!
Great video and worth watching multiple times

What is the font at 15:41? Looks great to me.
@Alex Forsythe Thanks for the reply. And continue this great work.
The typeface used for source code is Consolas, which is included with Windows. For most other titles, I use an open source font called Mohave.
en.wikipedia.org/wiki/Consolas
github.com/tokotype/Mohave-Typefaces
This is an amazing explanation
What do we have to do to get this guy to start making videos again?
About how many players can run on this? How does it preform with a large number of instances in close proximity together?
a gate way of information. very very useful. dont you dare take it down i will need this later :)
can you make a video about multiplayer racing game ? when the car of player A collide with the car of driver B, how does the system understand the physics?
Fantastic, thanks!

Trying to make a soft you hear in your head co to life might be the hardest part starting out but I guess that requires so solid
Have you been able to replicate webbrowser? Im trying to use a webbrowser for multiplayer setup but i cant get it to replicate.
Honestly, quality of these videos are so high that I hope Epic supports these with something like MegaGrants.
Subbed... I need to check if you updated this for Unreal 5, but I feel most of this info must be still good.
Wow.......That' s so cool. Keep going Sir. TNice tutorials motivtes too.
Fantastic video!
Great video. Thank you
Well, thanks a lot, man. Please tell me what program was used for the presentation?
