Ty - you the MVP!!! Love people like you who make these comments, so much easier to navigate long videos like this! Appreciate it
@@chadtheall682 cheers bud. Hope you create some exciting worlds :)
Thank you sooo much you can't imagine how your comment helps me Thank you !
Great talk. This really gives an informative overview of all the open world tools, their importance and how to take advantage of them.
My only gripe (which is not towards the presentor) is there unfortunately many times the presenter is explaining things on screen, and the camera either doesn't cut directly to it or go picture in picture late, so some of the time you are wondering what they are showing or talking about.
Otherwise, very done.
This is a problem with all of the uploads from this UnrealFest. Whoever edited them didn't seem to realize that the relevant information is on the screen, not the person standing on the stage.
Yes, very annoying.
I honestly don't see how this is a massive issue with the talks, we really don't want to see the person but what they're doing with the engine
I'm learning Unreal now and I'm leaning towards level design the most. This is awesome thanks for it.
Hi I'm planning to make a game using UE 5. But I have no background in coding. Is it impossible without coding or ??
@@edwardelric8966 it's possible with blueprints
The hardest part will be forcing lower LODS on all of these auto-placed assets 😅
@@edwardelric8966 you can use blueprints so you don't need c++ to make a game but in some cases it may be wanted to use c++.
Great overview and presentation. Its really helpful to have everything needed in one video and you can research further as needed.
Great show. The talker talked a perfect representation and experience, the content covers the UE5 partial fundamental and the talker action and experiences is very fitting the highlight.
24:00 - Correction, Ark did not use the First Person template. It used the Shooter Game learning project as its foundation.
Edit: spelling error
Correction - 21:00. Also, "Shooter Game", not "Shooer Game". Seems like a trivial mistake to point out, seeing as how everyone should have gotten his point.
@@Derjyn yes, thanks, that letter somehow got eaten by the typing gods.
and it still says ShooterGame.exe in the task manager lmao
Very helpful to get ideas on completely unknown systems.
Although I wish the camera cut to screen were more in sync.
what a beautiful man.
ok
Great stuff
I would love to know how to set up a open world without using the template. Also why show the speaker and not UE? and when they do show UE its so small I cannot see most of the time.
Chandler gave a good talk
All those great tools but for multiplayer Layers does't work you may say it's normal, because a player may be on this zone and you could see a player floating around but for a TopDown game it could be very usefull. The only thing that work in multiplayer is WorldPartition but if you have openworld and you got 15 players and they are all on the map... world partition will load those proxy zone because there's a player that play on that zone so this will affect performance.
Thank You very helpful info.
Need a new talk for 5.3 and displacement
What is the largest map size in Unreal Engine ? is it 88.000.000 Square KM ?.
Saw in another video that they were supposed to have increased from the old size to a massive size..
Sure. I hope you have a massive circuit board and power supply to run that 2 million dollar cpu that will be required to run that.
@@avistryfe4534 Ow ? Thought the engine is supposed to "stream" ?..
@@NecroViolatorlol😂, I think Ram might be more important than cpu in that case
Thanks a million for this! Quick question; I would love to use the template, but 2×2 km terrain isn't very large. I would like to create a new and much larger terrain with the template. Can I just delete the default terrain and create a new one, or will that mess up some of the template settings?
I didn't try it out, but if you just delete the landscape and replace it, there shouldn't be any changes to the settings that come with the template.
If i recall right he even says in the video that you still can replace the default terrain that comes with the template.
You could also use the empty open world template, you just have to add the sky atmosphere etc manually.
@@revan9903 Thanks for replying! Yeah, I figured it probably wouldn't hurt to delete the terrain, but I'm too nervous about being wrong, so I wanted to ask just to be safe. He mentions at 14:43 that you can import a custom height map, but so far I haven't seen anything about deleting or replacing the landscape though. I could be wrong, I'll go through it again.
I was also thinking about the empty one, but then I'll have to set up world partition, one file per actor, data layers, HLOD etc, all the stuff I'm not sure how to set up, so I figured I'd be better off using the other one. I really appreciate all the help I can get of course!
Another option would be to set up all the things mentioned while following the video, but I'd recommend just to create a new project with the template, then deleting the terrain and then checking if things like World Partition are still enabled.
@@revan9903 Yeah, I think I'll go with your recommendation here. It seems like the safest thing to do, go with template, delete terrain and go through the checklist of tools. Thanks again!
Just open an empty one. The stock one with the deserty looking thing is a trick. There is even a unreal logo printed in the center of it that you cannot get rid of. I guess someone down at unreal who made the stock level didnt want anyone stealing it......however that makes any sense....
Thank You
His notes were messed up so good thing he knows what he's talking about lol
Creo que no es para nada necesario quitar las pantallas del ordenador y poner al hombre para que se le vea...quiero ver que hace mientras explica, gracias....
How do companies design giant games and the performance remains stable, while we just put a few things, the game becomes heavy UE5
LOD Optimization
if you watch the video, it answers your question
World partitioning
Because you didnt optimize it? 😂
UE5 games have poor performance, use Unity instead
So, does the streaming only work for landscape object or does the partition cells automatically include the static meshes on that area, including all the verticality?
can you give us a list of every setting to enable so we can do it on existing project
If only streaming on would have a setting for opacity😢of terrain and meshes, or is there such a feature?
What about an open world thats always loaded with active parts that just stop rendering outside of camera view? Didn't that become a thing?
Thank you UE Zaddy 😏
Where is now this template in 5.1 ? It's seems to be removed from the Engine?
did you find it? I can't find it anywhere
@@deepelements Yea you have to follow exactly the steps and go File > New Level, than you will see the posibility of creating inside already created project an Open World Level.
Could I hair remove the map and add my own to this and still use all the stuff in it?
I went with the template, deleted the default landscape and started making a new one, but now I have the problem of what settings I should use for making such a large one, and at the same time make the landscape as effective and useable as I can? Will World Partition fix everything no matter what I choose?
I've gone through the Landscape technical guide for UE5.1 and set up landscape according to the "Recommended Landscape Sizes", but the largest one there is 8129 x 8129 vertices and I don't even know what that means in Km. I've found somewhere that it's been said that this would translate to something like 8.1 km, but my questions is:
how do I make it larger? and is the best way of approaching this to make one massive landscape or several small ones put together? And if so, how do I meld them together?
I have to stress that I'm NOT interested in importing landscapes, I have to make it new inside UE5. Everyone I've found that has tutorials on this seems to either just focus on importing heightmaps from thirdparty software, or just shows how to make small landscapes. How do you just make a large 70x70 km landscape in UE5 and what is the best approach? It doesn't necessarily have to be 70x70 km, but think somewhere in the line of double size of Skyrim for instance. I read somewhere that Skyrim is 37 km.
I've asked the same thing in a couple of subreddits, but I've gotten no answers yet, so any help on this would be so much appreciated. Thank you all that has taken the time to read this!
would like to know that too.

@@mobildisko579 Thank you!!
Where's the template ? I mean the one he work with.
Why can't I make a 100 k Square landscape inside UE5 .
Virtual Textures being enabled can really f**k you in the a** later down the line when using Megascans.
I’m going to make the game that I e always wanted to see happen.. 2 actually

Anybody know of a good tutorial video to do planets?
u gonna go build minimap, what thats gonna do is actually build your minimap lmao
❤❤❤❤❤❤💯
I really hope CDPR manages to make this work for The Witcher. I don’t care about Nanite and all these whistles. Just give us the most multi-layered and big open world you can make.
WHERE THE HELL is the open world template? >
just do new level -> empty open world
31:00
use the freakin template damn it!!! :'D
Template is garbage. Has unreal logo hard coded into the center of it. I tried lowering the terrain and im lile why isnt this going down? After clearing it all i zoomed out...unreal logo. Unchangeable in the stock template. Nice joke.
@@avistryfe4534 bro look up landscape layers, the logo is on another layer
"look at all these rocks i have over here."
wouldnt that be helpful.
all these videos are missleading, why no one talks about performance... -.-
That's not what misleading means. Missing what could be important information, yes. But not _misleading_
There is a hole extra video from the same Unreal Fest that is completely about performance. You can find it on the site linked in the description.
and you gotta sack the guy who edited that video, he constantly talks about stuffs on the screen
we dont see the FUCKING SCREEN !!!
F your template. We want games that will feel unique to what they are entirely. Fresh designs for specific worlds.
I hate this way of thinking.
when I saw this new system, 1 asset = 1 separate file, I couldn't believe for an hour that they really did this. Do you need 100 rocks on your level? Here you are. You have 100 separate files in Perforce for this. I wish luck to everyone, who will use this on AAA projects. Probably, it'll lead to a massive suicide among level artists in the future when they try to find a proper file and proper version among billions of them. Will see.
Unreal has a perforce integration which handles all that itself
@@kokokokokoko201 You open a map and you see that some assets disappeared. How are you going to find who and in what changelist made this change?
@@kokokokokoko201 and no, it doesn't. It has an extremely limited toolset from Perforce. Everithing that it does is showing the actual names of the assets. I don't need this. I need a classical prefab system every major engine in the industry has.
CHance for a BIGGEST LETTER icone names and use a BIG MOUSE cursor PINK OR RED.
i can watch what are you doing.
PUT your windows screen to us. I dont wanna watch your 3 monitors and 240p windows screen of information software
This is a presentation video, it was made for the people in the room not the people on RUclips. Maybe say thank you for the free content instead.
I want to make red dead redeption 3 but you are taking money ı need money and game to be a elon mask
Wtf is a H"LOD"? It's an acronym. You pronounce the letters.
Hierarchical Level Of Details
What an annoying person! Drinking water every 2 minutes, messing his words and his notes, look stressful, making so many mistakes. HTF chose him to present?
he probably was nervous calm down
