Overcoming Common Early Challenges in Unreal Engine | Dev Days 2018 | Unreal Engine

[@hyperforce]

Still awesome to see you haven't changed Zak, still entertaining and informative to watch you present.

[@urbantwilight]

More videos with Zak, please.

[@phantomapprentice6749]

@ yes, not sure what happen to his channel though, its all about offroading now for some undeclared reason.

[@DodaGarcia]

When he went “isn’t it neat” I lost it

[@HangryBunniesFromMars]

One of the best talks ever. The only thing I think it was missing was a general outline of where stuff goes in the general Framework of UE4. I had UDN for a short time and if you can afford it, go get it. I got answers within hours some times and always straight from their top people. If you can't the unreal reddit community is awesome helpful and alive.

[@petertremblay3725]

It's quite bizarre to see that the worst place to get help is the unreal engine forum!

[@terraint3697]

I love this video. I think I will recomend this to people who are new even. Give them things to keep in mind as they start developing their first game.

[@aryanjha8841]

8:41 you got to love the fact that they use that one tower in tilted as an example and not something more detailed.

[@kevalshankershreyas9672]

I'm a simple man.I see Zak Parish. I hit like. 😉

[@SpheraculGames]

Yeah, what a dull audience though..

[@DodaGarcia]

My start with Unreal was a bit rocky but how can you not fall in love with them after the Bluetility thing? Like the amazing visuals weren’t enough

[@KoyFoster]

Nice. Both ears can learn now.

[@davinsaputraartandgamedev9453]

I can't seem to access the UDN. All I got is "The resource you are looking for cannot be found. Please try accessing your community here"

[@babytime1]

i luvvv zak, aint nobody teaches me but this fucking tech artist right here

[@snowfox5275]

My right ear is now happy thank you guys

[@KoyFoster]

I don't suppose there can be a tutorial on work-space workflow for project management? I understand the UE4 well enough, but I can't seem to get a workflow going. I can't even begin to outline the project.

[@TheAxebeard]

Literally just write an outline of your game.

[@Morgwic]

So Boolean checks are really that heavy? What are you supposed to use then instead?

[@ThatRyanManning]

Wish this talk were longer. Lost of good info packed into 45 mins.

[@chiyungchu9463]

18:18 When i try to open the kite demo, my PC crashed /.\

[@jintarokensei3308]

Man I coulda used this info 2-3 years ago when I first started :(

[@jeremyanderson6395]

Is this the Montreal talk?? You beautiful people! I hope my dev career takes off, but I hope to have a company one day as open ear as you all. Thanks again guys!

[@Nickadermia]

This is great! Is there maybe a link to download the presentation? I'd like to print out some of these slides for reference if possible.

[@davinsaputraartandgamedev9453]

can anyone please explain a bit about what he meant when he say hard references? What I don't understand is casting is considered a hard reference too? If I have a different Item Class, and I want to interact with it, should I actually cast to Character from the Item Class itself? So it's more like many to one, rather than one to many. What I was thinking is to use Interfaces for things like these. Are interfaces hard-reference too?

[@JeremiahT]

He's referring to "casting out" which implies using a "Find Object/Class Of Type" node. Interfaces are a solution to this problem since the player doesn't need a reference to them until an interaction takes place. At 29:42 he says "use instances for blueprint communication" but he meant to say Interfaces.

[@harrysanders818]

Gold. What a great talk

[@DeathClonic]

Where is UDN?

[@randysewell3199]

You have to have a custom license to access. IE you are part of a development studio that has worked out a support agreement with Epic.

[@DeathClonic]

That seems expensive for the average indie dev lol

[@Deck_Dynasty]

Exactly. How BS he framed it like it's easily accessible by most devs. On the slide he even said, "anyone who's a developer".

[@darodism]

28:19 First Audience member made a sound. Reason, 15 SECONDS!!!!! The team he was referring to was the Devs of Squad Offworld Industries cough cough.

[@mr_StevenS]

Is there a pdf/powerpoint file with this presentation?

[@thetrivium2261]

The blueprint stuff is kind of depressing. The performance disparity is greater than I previously thought. I presume for the slow-moving VR experience i'm working on it won't be too bad? I'm not building a multiplayer game. The info on Tick helped immediately.

[@Robbe1912]

try to keep your functions as simple as possible, almost never use tick and use forward rendering. also use as little graphical features as possible while still keeping good visuals. im working on vr experiences aswell and developing for it made me very cautious regarding performance. you can totally get a good looking and working game in blueprints, the ease of use just encourages bad habits i think. my main problem is that i am working on a multiplayer game and replication adds another layer of performance hits...

[@Chris-jo1zr]

I think, in my amateur opinion that Blueprints are there completely for "artists" use and as soon as anything like a real performance comes in to scope then you need the C++, the coders, people who are paid much better than artists to make these things work perfectly. But I also think a whole lot of simple things can be done in blueprints, there must be thousands of mobile games that use them or even app based programs.

[@thetrivium2261]

​@@Robbe1912 The best answer I can find is to nativise to cpp before testing/shipping. The words "blueprint allows artists" are ringing extremely loud from the early engine evangelism, though I don't think they oversold it. We're desigining with co-op in mind, but not necessarily as a shipping feature. Leaving the appropriate gaps to plug in some replication where possible. Since I won't have PvP the idea i've struck on, and anyone is encouraged to point out the flaws, is to not replicate all the controller and hmd position, etc. and instead have the server handle it like a traditional fps pawn. If i'm waving my arms around locally - all you'll see is a traditional style character that is at best updating it's aiming. I understand this presents it's own problems and undermines the sense presence that VR promises but players will be spending more time playing than waving at eachother. Gesture support is maybe a workable alternative for some personal interaction. The first thing I played on my Vive was Arkham VR and it became immediately apparent body simulation wasn't going to be polished for a while, it was going to take far smarter folks than me, and Batman needs an orthopaedist. It's early for me, I can't tell if what I just wrote made any sense. Need coffeeeeeee

[@Robbe1912]

i recommend using the vr expansion plugin. dont underestimate the importance of presence and seeing other players gestures! that is one of the most important things in vr. just simple objects for head, body and hands is enough.

[@richardtoth7240]

how much does a UDN cost?

[@KodakYarr]

Fantastic talk. Thanks for sharing it!

[@pratiktarale8103]

Thanks for reuploading

[@ChuckWilsonWilsonsStudio]

Zak cracks me up. I should be announcing a baseball game roflmao

[@devcor]

Yeah. Didn't see much videos from Unreal channel, but this one - it's definitely a like. This guy knows how to act, how to handle himself on stage. He knows what to speak and how to speak it, so there's, like, zero "uhm"s and "errr"s. People shhould learn that from him. The only thing I would like from this video is a better sound. Guessing the mic was too close to his throar, that's why that strange sound with constantly changing volume.

[@SamuliTuomola_stt]

@@devcor guess one could always prepare more but other than that there isn't really much to learn to not stumble over your words

[@__-tz6xx]

35:30 Zak is an Oracle, he foretold what would happen with Cyberpunk 2077 launch.

[@IIStaffyII]

What is culling? 08:10

[@Deadener]

It's basically the engine unloading objects in the current runtime that don't need to be visible. There are several different ways an engine can cull objects. Some search terms for you: Camera Culling (automatic in most engines), Portal culling, Occlusion culling

[@doop00]

Basically it means to make objects you're not looking at directly to be invisible to save performance (no need to render objects that you can't see behind you) UE4 does this by default but there's also other methods of culling you can do if needed. You can learn more here from their documentation docs.unrealengine.com/en-us/Engine/Rendering/VisibilityCulling

[@ToadieBog]

We get it. If you are a serious game developer, please go learn C++. Regardless of how clunky, archaic, and flat out cumbersome it is. I get flashbacks to getting the same attitude towards business apps in the late 90's, from mainframe programmers.

[@genlee2354]

WOW! Zak beautiful hair!!!!

[@450aday]

BP reminds me of Queries in AccessDB. Access database makers will use Query to generate SQL, then simply throw the Query away. It seems like the best way to use BP(in many cases) is likewise, to generate some C++ with it, and then throw the BP away.

[@morganwardfilm]

Yes, that’s exactly what u should do. BP are a great way to familiarize yourself with Unreal and c++ syntax, but inevitably they will slow everything down

[@dennisgarage9028]

I remember Zach from 3DBuzz. Was terrible watching buzz's cancer take over.

[@eatmykwad]

awesome stuff :)

[@Radicalshikami]

why no one told me my code was trash?

[@mrstarfire9336]

Honestly this is a great talk but ...It does make me feel overwhelmed and out of my depth..

[@YoloMonstaaa]

Its something to grow into, dont be afraid to revisit :)

[@jbach]

This is the way...

[@PauloSamurai]

Good!!!

[@AgentSmith911]

I rather have games like PUBG run on a constant 60 fps with downgraded graphics on console, than the 30 and drops to 15 that it has now. Developers need to focus more on framerates.

[@bexplosion]

You have probably enjoyed watching many movies at 24 fps without knowing.

[@AgentSmith911]

@@bexplosion Movies are best viewed at 24 or 30 FPS.

[@EyefyourGf]

@@bexplosion You are probably trolling,but whatever i'l bite,movies are fine with 24 frames per second,because there's no interactivity,and everything else that comes with that,and having stable 30 fps on games is playable,if it's locked,but if you are going from 30-15 it causes input lag etc,breaking immersion.

Hi, my name's Armando. I'm an artist, and I program. "Hi, Armando..."

[@lethiagames9208]

unfortunately" janitor model" people never do their jobs, sinces there's always alot of unused beta content in games on gaming history.

[@x-techgaming]

"It's very easy for artists to make your world look beautiful" Right; making AAA game art is "easy". Good one. I guess that's why everyone does it.

[@KimboKG14]

got asked about how to start learning game development, showed this video... step 1: english!

[@vince4417]

If you don't pay for an Epic Enterprise license you are Joe-the-Fortnite-streamer. Ok. That hurts.

[@iamisandisnt]

Did somebody say automatic instancing?

[@morganwardfilm]

Do u know if that’s a thing yet?

[@iamisandisnt]

Did somebody say skeletal mesh reduction?? :o

[@schoolhomevrtechnologyassi6286]

Epic support structure? Like... the godawful forum or 'answers'? IT IS FOR TO LAUGH!

[@cgtechie]

what is that weird vibe? oh wait.. it's just dead silence.

[@petertremblay3725]

I can see a lot of juveniles crying over the fact they will never be able to make a game only with blueprint! Well i guess it's a good thing if it's mean less survivalllllll with zombieeeeee game!

[@devcor]

For some reason they're doing that with Unity mostly... And damn, still too much survival zombie horrors rpg sandbox mmorpgs from those guys :D

[@spacepirate9882]

It depends on game type. Epic works most on competitive multiplayer games without high-end grapichs, than open world solo games with a lot of detail. In this case, the gain of few milliseconds on the game thread is absolutly useless when the bottleneck is on the render thread and you have no requirement like low ping, extremely slow input lag, etc. It's like using an high end CPU with a low end GPU, you won't gain any fps. Plus you can now use the nativization tool to convert your blueprints in C++ and get almost the same performance than with pure C++ code.

[@spacepirate9882]

oh and I don't think it's a problem for indie devs to make a shitty game which runs at 50 fps intead of 60 on the same config.

[@spacepirate9882]

@Akira You should read how nativization works and how BP is slower than C++ (it's a matter of virtual machine, not about "control") docs.unrealengine.com/en-US/Engine/Blueprints/TechnicalGuide/NativizingBlueprints
