@silent harbor I do them when I can it's just at this point most things are getting more complicated to cover heh
silent harbor
@kindred viper a little bit clearer, thanks!
Haha I can imagine. Was hoping you would cover some new things from 4.24 but I reckoned you were busy
grim ore
@jaunty cedar chances are that is a hard reference and a hard reference has to load the referenced item in order to access it.
silent harbor
Pleasantly surprised to see your writing here
fathom glade
*frustum not frustrum
grim ore
@jaunty cedar basically in order to keep a reference to it in order to access it the entire thing gets loaded as you noticed. If you do a soft reference (just reference the class itself) you will not have the cost of the entire object being loaded
jaunty cedar
Thanks!
grim ore
yep its good you noticed it, imagine referencing your character or something else in your main menu for example and then your entire game loads... it's... uh not uncommon to have that happen lol
kindred viper
@fathom glade my bad. I keep doing that. It's like a tick now
jaunty cedar
I'm working on a blueprint tutorial, coming from a background of C++ and having done a couple smaller games in Blueprint, but adjusting to BP coding practices where there is less significance* of pointers etc when trying to promote and explain good practice etc is annoying. I could have prepared better, but luckily, there are no glaring issues (besides a slightly annoying cast that can be fixed later) in the next ~5 episodes that are scheduled for upload, and I'm spending a bit of time with a backed up copy of the current progress and fixing everything up so I can dedicate a longer video to cleaning out the code a bit. Pretty important considering it's basically a full course on making an online loot shooter.
grim ore
holy hell I just noticed .25 is the next version, thats 25 freaking updates to the engine
iterate, iterate, iterate 🙂 it's a programmers life for sure
kindred viper
@jaunty cedar there are pointers in blueprint. There are also Refs. You have to explicity call by ref though
dawn gull
So you know how in Windows you can make hidden folders that you can only access when you type directly in the directory?
(Oh sorry to interrupt)
Well is that possible in the unreal content browser?
random holly
Hey guys! 👋 Could anyone possible help out a UE4 noob for 5 minutes please? I’m having problems setting my animation montages up
kindred viper
@dawn gull not by default, but you could goto C++ to do it
random holly
It would be muchly appreciated
dawn gull
Awww ok
grim ore
might be able to add to your personal content folder but its still there
kindred viper
Technically you could replace the entire content browser. Or extend it. But the directory thing is tricky because windows file permissions and how the content browser displays are entirely different. You would have to have some kind of interface for doing it
edgy halo
My team is running into an issue which means we cant use scenerendercomponent2d for our scopes and mirrors, is there another way to do it?
grim ore
@random holly#animation might be better focused for that specific question but if you are stuck after following the docs people in here might be able to figure out the problem
random holly
@grim ore Okay will look into it now 🙂 thank you for the reply
kindred viper
@edgy halo with HLSL and a material to deal with it I guess
I mean, whats the issue with the scenerendercomp if I may ask?
edgy halo
its a vr specific issue
kindred viper
aliasing?
edgy halo
the fps dies when they start capturing
kindred viper
ahh yeah it would but how many do you have?
edgy halo
yup
but its only when its rendered to a texture
no matter if we show the texture or not
kindred viper
I've worked on a game that used it for a HUD in VR and it wasn't taking much up at all tbh. It even has material post processing on it
grim ore
oooh Chaos is enabled by default in .25 right now and there has been a ton of work on .25 in the master branch. I wonder if that will be a big focus at GDC this year
edgy halo
its apparently a new problem from 4.23
kindred viper
ahh I see.
edgy halo
no clue how hlsl works, might be worth looking into?
kindred viper
well its a hacky workaround and I have no idea of the cost, but you can get pixel information and output it, so technically you could recreate a rendercomp in a 3d world (non-camera based) but like I said, its hacky.
edgy halo
ah
goddamn this is so annoying, it completely kills scopes for us atm
when they are enabled, something called "framerenderfinish" in stat gpu goes up 10ms from 0
kindred viper
have you tried recreating a scope with the same method in a blank project and seeing if its got the same resource cost, or profiling deep and seeing if there is a hitch somewhere? Or is this a known issue that requires an engine/commit update?
edgy halo
its a known issue and we tried in a blank project :/
kindred viper
fixed for 4.24?
edgy halo
nope :/ running 4.24
kindred viper
wow two versions with a buggy scenerendercomp. I mean... its kind of used a lot. Would think a fix was on the way at least
edgy halo
we alleviate the issue a bit with r.SceneRenderTargetResizeMethod 2
if its default as 0, we get around 20ms
from that alone lol
so ridiculous
kindred viper
are you simulating the whole eye2scope movement? ie. just going from regular to scoped with no animation, just transition?
or is it manual from the user?
edgy halo
manual, having a basic mirror does the same though
the camera is completely disabled when not close for our scopes
kindred viper
I would say, if you wanted a fakery method, that once the event for "IsFullyScoped" or similar fires, switch cameras. Dont use a render comp, instead have a custom cam that does the same thing, but doesn't need the other cams active
ahh
sugar you beat me to it :p
edgy halo
haha ^^
can we use a normal camera and render from that to a texture somehow?
could that make a difference
grave nebula
no matter the fov``` That is not unexpected.10ms is a bit harsh dont you think?
edgy halo
when we have to stay under 12ms for vr
kindred viper
I mean, I wouldnt even consider it production value for 10ms
grave nebula
Depends on resolution, but overall, on par.
silent harbor
@grim ore are volumetric lightmap fixed for level streaming in 4.25?
kindred viper
yeah sounds about right
grim ore
@silent harbor I dont know, I did not see any changes to it in the notes
silent harbor
So what alternative is there if you want level streaming with baked light and have dynamic objects to be lit correctly? I heard it’s unsupported/broken
Would be awesome if it got fixed
kindred viper
i dunno. if you have a lightmass volume, you should be able to keep it confined. Not sure about it fully tbh as I had that on my life of thing todo. I mean, you wouldn't get far in an open world game engine if you couldn't level stream lighting in such a way
im sure there are plenty of issues though
caveats so to speak

Is there a way to export the contents of a blueprint and copy those parts out to past in the world for editing, there's times when I'd like to edit building and it much easy out in the level space that it is inside a blueprint, ALT- drag to dup for example does not work inside a blueprint
edgy halo
@kindred viper can you maybe guide me in the direction or know a guide on how to setup hlsl for my purpose?
pseudo grotto
Hello, I send you a question. I have opened my Unreal project on another computer with the same version of the engine. Upon returning home, he has deleted all my favorite folders and told me that at my level I could not save any of the changes made because he said:
"You do not have sufficient permission to save the following content to disk"
As a result of this I have closed and opened it once more, however now, that lvl if I check it from the folder weighs 0mb the asset and in Unreal it does not read it directly to me. It is as if I had deleted it. Does anyone know something?
frozen pond
so my project crashes after updating to 4.24.1, problem is my struct, after manual replacing it in folder it works only 1 time - until i restart, its playable before closing project
Any idea what might happend ?
dawn hedge
Someone please help, Unreal engine keeps crashing when i try to import fbx models.
i dont know how to fix it
kindred viper
@edgy halo its as simple as using a Custom Node in a material and typing in the HLSL there.
@silent harbor good read. thanks.
fierce tulip
@dawn hedge could be anything, version of software you are using, fbx version, export settings, import settings, very messed up mesh, etc.
dawn hedge
@fierce tulip i am using Mixamo. Some models do work (the ones on their website) but when i take one of my models and import it onto Mixamo and import it onto Unreal Engine it crashes it
worldly dust
is 4.24.1 stable for a beginner to learn off of?
dawn hedge
i got these errors when it crashed
fierce tulip
no experience with mixamo
@worldly dust i'd suggest .23 or even better .22
though when you just start out you probably wont hit snags in .24
worldly dust
thank you, I had heard there were crashes relating to animations, they did fix it in .24.1, why would .22 be better then .23?
abstract relic
Sounds like a case of a poorly made model, not an issue within Maximo itself
fierce tulip
besides some oddities, .23 is also fine but has some shipping issues for some people
worldly dust
okay, I'll stick with .22 for now, thank you for the advice, I figure it's much easier to try to upgrade a project then downgrade
fierce tulip
you cant downgrade really
abstract relic
You can’t downgrade
worldly dust
oh lol, I have never tried so even better
abstract relic
Wisdom by experience is the bitterest 😜
pseudo grotto
When Unreal does autosave, where do you save those files?
pseudo grotto
And how is an autosave loaded? @normal burrow
worldly dust
are there UE games out there (EX: Sypro Reignited) that utilize epics character class and character movement? or do these studios make their own? really the question is should I be learning epics already implemented systems or learn how they work from scratch
fierce tulip
really depends on the game i bet
kindred viper
you should learn the CMC just to know where it's going to bite you in the proverbial. Even though I hear rumours it's getting replaced.
obsidian lily
hey everyone-- I'm doing some due diligence before potentially using unreal for my next project. Question: my game will need to dynamically combine meshes at runtime. Is there an existing way to do this?
worldly dust
even if it gets replaced I'm sure it will take quite a while to actually be ready for commercial use, thank you I agree it would be best to learn the CMC, I am way too unskilled to try to make one as a learning experience
obsidian lily
expanding a bit, modular objects will be player placeable in the world, and there will potentially be a lot of them, so when the player isn't in edit mode I want to combine these objects into a single mesh, mostly to reduce draw calls
kindred viper
@obsidian lily yes you can. I haven't done it but I have seen things from others that tell me its possible now
don't forget that in that kind of "editor" sense, you can also go external to C++ and use code to make things outside of the engine and pipe them in so to speak
scenic hatch
how do you make text glow in ue4?
i thought you would be able to just drag the emissive material onto the text
seems you cant
kindred viper
@scenic hatch I always do my glow externally. It seems like an overkill effect to do anything other than fake it really.
is it static or animated text?
also there is Rich Text in UMG which might have something if you need.
scenic hatch
@kindred viper its just static text mate
its in a dark area though
wanted to light it up
kindred viper
you can still apply emissive nature onto your glow texture in the material. Although I don't light things with emissive either.
abstract relic
Gotta check first. Did you set your materials to UI? I thought they’re all technically emissive

Puh... How come adding a simple comment to a material and saving makes it recompile the entire material? 6k Shaders left.
abstract relic
you don't need to compile when adding a comment. Just save the asset
calm widget
Sure, but when i save it automatically compiles?
abstract relic
no
calm widget
Well, that shouldn't have been a question. I'm telling you it does 😛 I don't know why, it makes no sense. But i'm getting so much bugs lately i don't even know what's going on, changing a materialfunction input name, another materialfunction stops working...
Was kind of slow there, also it wasn't compiled before, but it does that anyway.
kindred viper
there is an option to compile on save. just need to turn it off.
grim ore
there is?
calm widget
I need this, where can i find it : )
grim ore
there is an option to save on compile for Blueprints
kindred viper
its not there for material editor?
grim ore
it's not there for anything as far as I can tell, the reverse is (save on compile) for BP only
kindred viper
im having a derpy moment then. sign that I should goto bed
grim ore
It was a good idea lol but as far as I can tell materials have to be saved when you close them and compile them or they get mad
if you notice there is no compile button for Materials heh
calm widget
I got another question about saving, when pressing "Save all" in UE, how come i'm always confronted with prompts from every single tab that's been opened to save them? Takes me 5 minutes to save everything when working for the entire day.
kindred viper
Honestly I do such little material work, I should have just closed my eyes and not opened my mouth. The will to assist beat me. Anyways. gl hf im off to rest for another day
fierce tulip
they shouldnt pop up when they are already saved
grim ore
that is weird for sure as save all doesn't prompt me here 😦
fierce tulip
only maps
calm widget
And consider i have maybe 30 tabs open
Normally
Then there is the final prompt to save all the things you've already been prompted to save already after closing?
grim ore
I think save and save all just saves the map itself and not the assets
and the materials compilation/save is separate from the asset saves
fierce tulip
i never use that save-all, but the one in the content browser
calm widget
Even so, going through them all and saving manually, i'm still getting the pop ups to save everything when closing. And the final one doesn't make any sense, cause it lists all the things i just saved, and asks me if i want to save them?
fierce tulip
doesnt do that for me in .22
grim ore
cross references possibly. You save materials which update objects in the world which then needs the objects saved again as they are now dirty. etc...
I can say I don't have that issue in .24 but I don't keep extra items open and I always save when I close a tab and I don't work with materials which seems to be a biggie for you
calm widget
Hm, yeah. It's nothing really, just figured i cant be the only one having this
Speaking of .24 i'm having these weird flickers with HeightFog, even on new projects.
scenic hatch
when you build your lighting on high or production does it skip from 0% to 100?
calm widget
scenic hatch
because its been on 0 for ages
grim ore
@scenic hatch it can take ages depending on your machine and lighting settings, it should not skip no.
calm widget
It usually gets some traction though after it's passed 0% if i remember correctly, i use dynamic lighting only for my scenes so could be wrong. How long it's been going for?
grim ore
20 lights could take 2 weeks if you are running on an atom x5800 and you are using 2048 for lightmap resolution soo...... its like 20 lights or so doesn't really mean much
scenic hatch
@grim ore
is there a way i can build lighting for just 1 level?
thats why its taking so long i think
i forgot im building new level in same project
fierce tulip
only builds it for the current map
scenic hatch
fuck
fierce tulip
no, not on anything worth mentioning
calm widget
Anyone got a clue about the flickering in .24(From previous clip)? Pretty sure it's godrays related, i downgraded again so haven't tested a lot.
fierce tulip

@dawn hedge Also make sure you have no bones without parent, they will have their own root in blender.
grim ore
ah maybe its the leg IK bone and the pole target that are causing it?, the left ones look like they are unparented
dawn hedge
so how do i parent them (i dont know blender i just downloaded this model)
calm widget
I think Ctrl+P should do it, select the child bone first then the one you want to be parent.
dawn hedge
wow i have no idea how to do this
so how should i parent them if these are the problem
calm widget
You can pm me if you want, i've done a lot of work with armatures in blender. Don't think it should be discussed here probably.

what's a good place to store information about POIs? I thought about data tables, but they feel kind of awkward to use.
tawdry compass
Hi everyone, could someone tell me how to remove a listing in the looking for talent channel?
exotic thicket
if the POIs are relative to locations in the world, maybe you could store that information on a POI-Actor which is placed in the world or something?
fervent sigil
I need a way to access them all though, when saving progress (e.g. I completed that POI), or when positioning markers on the map
Also, I'm using world composition so actors can be streamed in/out freely, so I can't really base any global data on world actors
exotic thicket
Guess you would have to use a combination of actors and data then, assuming you can't query for every POI in the world if parts of the level isn't streamed in
fervent sigil
how would I save the data though? what are even my options?
exotic thicket
I was using a data table for something similar, although I'm not quite sure how well it's gonna work if I had a really large amount of entries in it
fervent sigil
the thing I hate most about data table is I need to edit an external csv file every time I want to change something. I'm pretty sure about it anyway, right?
exotic thicket
I just edit the data table asset directly in the editor
fervent sigil
😮 I remembered I couldn't. Why do you think it's not gonna work well for a large amount of entries btw? what's even a "large" amount ?
exotic thicket
well, the editor UI for it is very barebones, so it feels like it might get unwieldy if there was a large amount of rows and columns (ie. finding what you need from it to change it)
Although it does have a search function so maybe I'm just imagining problems where there are none... I build UIs at work so I have a bit of a tendency to do that sometimes lol
fervent sigil
haha cool. Well I'll give it a try and see how it goes. Thanks!

woeful snow
Ok so I need help. I am trying to loop through an array with a for each loop. It was working fine, then when I added an additional item to the array list, it broke searching. Once I removed the second item (so only there is one item - therefore the index is at 0), it fails to search through the contents of the array because of an index out of bounds error. What I am doing is using the index of the for each loop to access the contents of another array. If I subtract 1 from the index, my code works. Therefore, I ask, why and tf why? How does this make any sense. Why is the index starting at 1 now?!
Is this a bug?
The index should start at 0
swift spindle
you should clear an array first
woeful snow
But why. The first array contains 1 item now. The other is filled with data from the first. I should not have to subtract 1 from the array index for it to work. All I did was manually added an item to the array the for each is using manually in the editor, then removed it. Now the for each loop is broken
swift spindle
you should just always clear an array first
lapis vine
... one of these magic "just do it"

Ok I tried doing that and its still broken
Why would clearing do anything when there is nothing in the second? lol its filled from the for each

native adder
Does Unreal Engine support 2d vector graphics?
cloud cobalt
Like most game engines, UE uses textures to draw images
So depending on what you're asking exactly, probably not
You may be able to import a SVG and rasterize it into a texture that will be used in the game but that's the extent of it
cloud cobalt
@plush yew Have a block instead.
@native adder Depends what you call "pixelization"
All textures will be stored as pixels, yes
They won't necessarily be visible
sudden agate
<@&213101288538374145>
native adder
The graphics I want to achieve is one where zooming in wont show the pixel edges
snow crown
@plush yew chill out
sudden agate
@native adder You can use Shaders if you can compute the shape, but Vectors aren't a thing in UE.
cloud cobalt
It's probably for the best to look into another engine if you need 2D and vector graphics to be honest.
native adder
Im fine with alternatives
If I cant get vectors but have ways to achieve it, I can do that
sudden agate
there is always the possibility of having super-duper high res textures :'D
native adder
Also that
But really what im looking for is a system to procedurally generate textures
cloud cobalt
You can do that, depending on the zoom level, but it's not really practical and won't look as good as actual vector
native adder
Basic tho
sudden agate
can you give examples what you want to achieve visually?
native adder
Ye, I could
Lemme find something online
Something like this but 2D
Base body, then “detail” which is the base body but repeated at smaller iterations from the center of mass
I think a system like that would produce simplistic but fairly memorable shapes

So my dream project is a specific idea for a fighting game, i've never worked on games before and am really new to to unreal and have no programming knowledge in the slightest. Just today i've been trying to follow a 2D platforming tutorial so I can learn my way around Unreal although I tend to get frustrated with how often there are unexplained differences and problems with the tutorials I watch. Is there a better place to start or some recommended classes I can take?

Can anybody tell me how HapticFeedbackEffect_Curve assets work? The editor for that asset only shows the usual Save and Browse buttons. Unreal 4.23

@tropic jasper There is one from Tom Looman Multiplayer FPS C++ or something, that's good. The other one I would recommend is from Stephen Ulibarri "Ultimate..." something, its RPG.
tropic jasper
I’ll have a look into now, see what’s gunna be good, thank you 🙂

Just as a follow up to previous posts, I think I'm able to use Artv1 successfully. Pretty happy.
I mention this because, I didn't see a single comment in the past three years that said it could be done, so I thought it was completely deprecated and non-functioning.

@tropic jasper I have bought the same courses. Haven't started yet!!! 😅

Hello, why cant I change the opacity of a text render?

So there is someone streaming game dev with a thing called "Dreams" for Playstation and it has this concept of Wireless Transmitters and Receivers which I thought about and it actually might not be that bad to have in Unreal Engine even though it might be a bit overhead but it is quite convenient.
The idea is that you can make a Wireless Receiver(Event) on any object, give it a name and call it from any other object.
There can also be duplicates of a wireless receiver on the same object or on other objects.
exotic thicket
That sounds like a fairly typical global event listener system
plush yew
Sort of
But imagine it would be part of the editor, so you could go like:
Create Wireless/Global Event
and then do right click and it would show up anywhere
dim plover
Is that not just an interface?
plush yew
Afaik for a blueprint interface message you always need a reference where the message goes to
I mean you could do event dispatchers but setting those up is not as convenient

Guys, I'm waiting for rtx 3000. Should I get 1660s or 2060s in the mean time?
I could sell it or use it for machine learning later
normal burrow
Get something used
manic pawn
what do you have currently
hasty pewter
A 940m
And a GTX 700 something
But currently 940m only since the GTX is back home
So building new one
normal burrow
1660ti would be light years ahead
hasty pewter
I know
normal burrow
But you’d get a lot more value in used
normal burrow
Especially if intention is to move to marginally better amphere
hasty pewter
Ampere is for the RT cores and the final touch
I need something to start making stuff
Now 1660 super or 2060super
normal burrow
||rtx sucks||
plush yew
@normal burrow why is that?
hasty pewter
Baking at light speed with rtx
normal burrow
Faster noise 
dim plover
What do you mean by "everything"?
normal burrow
We’ll see. It’s pointless for the time being
hasty pewter
Most AAA console games
normal burrow
Not RTX
normal burrow
Nah
normal burrow
RTX is hardware
hasty pewter
Rdna2 will have hardware support too
normal burrow
It’s a specific driver based way of handling it
spark sonnet
1660 also has raytracing
hasty pewter
No not that please
normal burrow
It does yeah
hasty pewter
Shoot me
normal burrow
Have you tried Though akthem?
hasty pewter
Yeah why not
plush yew
I have seen comparisons between ray tracing with RTX and with GTX10 models that have the driver update and it showed that the GTX10 models with the driver update really weren't that suitable for real time ray tracing after all
hasty pewter
Tried what?
normal burrow
RTX enabled anything
normal burrow
I can assure you that it is a lot of marketing
hasty pewter
But it looks good
normal burrow
It’s cool for what it is but it’s not worth it for games
Cod uses it best and that is barely at all
normal burrow
I don’t think it’s value in marketing your game is high. But I dunno for sure
normal burrow
Megascans are pretty dope without RTX
dim plover
I do not have an eye for graphics, but is raytracing really that noticeable to most people?
I truly could not tell... even with before and afters.
normal burrow
No
hasty pewter
That's sad
normal burrow
It’s horrible
Everything you want RTX to do there are hitched to
Reflections have a bounce limit too
normal burrow
The noise is horrible on top of it all
normal burrow
Yeah idk I’ve got a 2080ti and don’t expect consoles to out raytrace it
normal burrow
But amd might have something amazing idk
hasty pewter
Yeah but we might get upto 16gb vram with the 3080ti
So rtx 3000 ftw for me atleast
normal burrow
Are they really skipping 2180ti?
normal burrow
They need numbers explained better lol
hasty pewter
You're right
dusky chasm
Hello guys, sorry to interrupt, but have you ever faced this problem?
My character is floating 2.5cm above floor level and it's causing me a lot of troubles with the animations.
It seems to be a common issue, but couldn't find a fix. My character has no Physics Asset.
Thank you!
normal burrow
If you drop the skeletal mesh component?
dusky chasm
That looks like a general workaround, but if I do that then I have issues with my animations using root motion :S
stark marsh
help im trying to add a melee combat system into my game and its not going well?!
i might need some help to set up a combat
i want him to attack then go back to the animation it should be doing like walking or something after hes finished attacking
wary wave
"That looks like a general workaround, but if I do that then I have issues with my animations using root motion :S"
One might question why you're using root motion.
but also, it shouldn't be an issue
thick minnow
Hello i want to do a tron like game where you can ride a tronbike. My question is does anyone knows how to make this laser trail? do i have to animate this or can i use particle system would be great if someone could help
grim ore
There is a ribbon particle you can use easily for that
normal burrow
Would think foot on ground would help root motion but I don’t use it
thick minnow
okay thanks
grim ore
@stark marsh have you gone thru the documentation https://docs.unrealengine.com/en-US/Engine/Animation/AnimHowTo/index.html there are tutorials on how the animation blueprint works
dusky chasm
i'm using root motion for jumping. I need my character to move to the position where the jump animation ends. Would you suggest teleporting the actor instead of using root motion?
normal burrow
Interesting use case
Character has means of jumping built in
Have you considered the jumping in third person template?
spark sonnet
Why does the first string execute when the loop is completed and not before?
wary wave
I would absolutely move the character, not use an animation
root motion is almost always more trouble than it's worth
plush yew
@stark marsh Depending on if you use a blendspace for the idle to walk system and its complexity you should check out the third person character blueprint and how it gets the float value to blend between those based on movement speed. I personally do an alpha of 1.0 on the X axis for a 1D blendspace then on blueprint update I get the velocity of the pawn, get its vector length, divide it by the max walk speed of the character movement component and set the blendspace variable as that
grim ore
@spark sonnet why do you think it's not happening until its completed, i assume you mean the Hello print string?
spark sonnet
Because its an array with over 5k elements so it takes some time to load and when its fully loaded both of the strings print
wary wave
your thinking is flawed
grim ore
all of that event happens in 1 frame from what I can see, print string, run loop, print string, draw frame
wary wave
because your operation takes so long, you don't see the frame update 😄
dusky chasm
in my game i need my character to perform 90º turns. Is there something more reliable than animation notifies to detect whether the turning animation has finished so I can apply the rotation instead of using root motion?
wary wave
yes, don't use the animation at all
rotate the character 90 degrees
and drive the animation through the character
this is how nearly all games work
those that don't tend to have all kind of problems
sonic pagoda
you guys have this issue on 4.24.1? delete a file that is referenced somewhere, editor freezes?
im having it across projects (some with source control and others without as well)
wary wave
it's probably going through all your references and ensuring stuff doesn't explode
and that will take a long time
wary wave
it has to go through ALL your stuff to ensure there aren't more references
that can be pretty slow
wary wave
your 4.23 may have been indexed already or something
sonic pagoda
idk, seems like a bug if it happens across all my proejcts.. especially new ones with not a lot of assets
wary wave
deleting an asset in this project takes several minutes (4.21)
sonic pagoda
ah ,i see... i guess the slowness finally hit me then
wish ue4 had some sort of progress bar for that though, cause it just shows that it deleted and then the editor freezes meanwhile
grim ore
that is odd then. When I delete I can see it loading all the references here before prompting me what to do before it deletes it from the project
sonic pagoda
i get that as well, but as soon as i press force delete
than it freezes
the solution is not to delete things 
or even better
dont create new things that will be deleted 🧠
grim ore
yeah it does that for me as well, I havent deleted anything in a while I guess lol
misty creek
Just delete them through the file explorer
grim ore
oy...
sonic pagoda
im just saying, not trying to pull rank or anything(becaused id quickly get outranked), but in my 3 years of ue4, this shit is weird
normal burrow
lol, important to be accurate
grim ore
agreeing with you now that I deleted something in a full project, one wav file is taking 2 minutes so far once I force deleted. No source control so its not that. 20% cpu activity on UE4, no HDD
sonic pagoda
is it still ongoing?
grim ore
and it failed to delete lol
normal burrow
question is, what cpu?
sonic pagoda
3800x
grim ore
i7-4790 here but its not even using 1 cpu
normal burrow
i saw yesterday a computer with vs taking 18 percent cpu on idle
ah okay yeah
20 cpu is probably normal then right?
(matthew)
grim ore
its must be doing more reference checks because after it un freezes it bitches about assets being referenced and still open and fails to delete... so you arent crazy @sonic pagoda
yeah nothing above normal on the CPU here
grim ore
so no issues on blueprints, the one having a problem is a sound wave
normal burrow
note to self: its quite nuts how well the 3800x compares against the 9900k
grim ore
and even then it's just this one wav, it says its open in the project but I have never played it or used it. Direct references work fine when deleteing (music referenced in the level bp for example)
the wav is referenced in a .cue which is used in some BP somewhere (deleting crap from an ALS test project lol)
sonic pagoda
im guessing they must have fixed that bug where you would delete a folder and it was still there and this time thign is the price we pay for having it fully functional? because i swear it was way faster in previous engines
grim ore
I dont remember it doing this either, the loadup to the "force delete" screen could take a while but not after. It would always fail quickly
normal burrow
one thing projects rarely do is just re-save all assets
its a good idea because if the project has been upgraded to newer engine versions it might be doing things to load an asset that it wouldn't have to do were it saved with the same engine version
if your getting problems with snappiness
grim ore
yep it's a reference thing. Sound Cue -> reference wav -> error after 2 minutes when force delete. wav referenced in BP -> delete immediate. Wav non reference -> delete immediate
normal burrow
this is ue4 in-game (3970x)
grim ore
like its checking references -> sees the cue so loads the cue -> deadlocks the wav as its now loaded -> times out with error
so you aren't crazy it's just specific things causing it lol
sonic pagoda
i see, yeah definitely these projects have been upgraded so it "checks out"
grim ore
well this is a new .24 project from the realistic rendering and oi opened all the wave files and saved and the cue and saved. still an error if i force delete. replace reference is fine
so its an issue with the node being abandoned in the cue I would guess
grim ore
with a play sound node in say a blueprint removing the sound wave will just make the node have no wave file to load and delete of those waves seem fine
2 minutes per test is.... annoying lol
normal burrow
2 minutes per anything in volume is yeah lol
sonic pagoda
yup, i've just been force closing ue4
normal burrow
actually i take this back
grim ore
I wonder if that's the issue where it can't handle "removing" references for certain nodes
what other types of force deletes cause this for you?
sonic pagoda
in this last case , in specific, it was a landscape layerinfo
grim ore
which is referenced in a material and in the landscape itself yes?
sonic pagoda
yes
grim ore
damn no issue here with a layer info lol
normal burrow
is the level with the references open when you force delete?
grim ore
it was for me now I have a black landscape
sonic pagoda
yes
normal burrow
pat really should learn more about how that stuff works with delete
hm okay
are you watching the log at all as this happens?
sonic pagoda
i didnt but i can find it and try to see what happened
normal burrow
one of the benefits to launching with vs is a output log that doesn't eat all resources with scrolling
wouldn't expect one to keep the output log open in ue4
but you could look at it, the information is going to be more relevant when you see the stuff piping into it real time though
if anything
ehrm

i dont think it was checked out at the time, since i had not edited it at all
but maybe it wanted to check out the file, before deleting it..
normal burrow
i use svn but have it hooked into editor similarly
i'll see what happens when i try to delete something not checked out
grim ore
mine is the same issue without any source control
sonic pagoda
yeah i had it in other projects as well without source control since getting on 4.24.1 none of them made in .24, but you just did make a fresh one
normal burrow
yeah it just deleted fine
but fwiw the asset wasn't in memory
didn't ask me to check out though
grim ore
mine wasnt even loaded, was in a separate level so its just simply trying to do it's and the assets are getting stuck
normal burrow
just double checking its not source control related, it actually rarely ever is
yeah
unreal just constantly grooming the snow or something
sonic pagoda
can you put a time to it monster, and does it actually delete?
normal burrow
what was in the stack trace if you don't mind me asking mathew

And theres a bug with enums,I don't know how to replicate it but it doesn't allow you to save changed enums,and when you get out and try to delete the saved folder it says the program is opened and theres nothing in the task bar
@sonic pagoda it does delete,but a simple deletion takes 30 secs

I don't understand why is there no main channel where you can ask main things that aren't related to the Programming Channels?
Or is it THIS channel?
sonic pagoda
welcome
grim ore
depends on what you are asking and what the #more-resources says
normal burrow
ye, read that
plush yew
It's this channel,if you problem is really specific then you go to other channels
normal burrow
if it fits no where else, it does here.
grim ore
@normal burrow doesnt really help, I dont have debug symbols installed so its just a bunch of useless stuff
normal burrow
ah gotcha
grim ore
and it only errored out 1 time, tried 3 more times same action and nada
grim ore
never use them they just take up space, I can run the source version if I need to
normal burrow
word
plush yew
I got a weird bug in only dedicated server where the character slides forward with no input,and debug says nothing
normal burrow
if you want to describe exactly what to do i can test it on source version
to reproduce i mean
my 4.24.1 is fully compiled on c++17 though, so its not exactly normal but would expect it to happen and could debug the break point @sonic pagoda and mathew
plush yew
I would like to create my own starting blueprint for a first person game. I do archviz, so some things like the gun are not needed, others I'd like to adjust -- the collisons to need to be adjusted, as does the speed the character moves at, etc. There are a lot of good parts in the one provided in the engine, so if possible I'd like to modify that rather than start from scratch.
That's how my movement system started
And i have kept it seperated and really customizable
normal burrow
you got rid of the gun right taholmes160? also @abstract valve may have some really like time saving advice for not using fps as the template?
I imagine there is something better than starting with fps for demo of arch viz
plush yew
I tried to but it didnt compltely work, and I cannot find the section where we talked about it here
normal burrow
ah you spoke with antoine already?
sonic pagoda
@normal burrow i'll keep an eye out for these errors, but mostly on my smaller project since this one currently is 80gb dont want to send you that, for your own sake, the other one is like 2gb so once the error occurs on that i'll shoot it your way ok?
plush yew
Why is your project 80gb?
sonic pagoda
3 years
normal burrow
oh yeah i don't have time to transfer projects really
plush yew
And?
sonic pagoda
of "content"
normal burrow
if you could just describe repro
sonic pagoda
i have like every asset pack (and it was actually 120gb, i deleted quite a few things)
plush yew
My project is a walk through, rahter than a still picture
@normal burrow
sonic pagoda
ah ok Pat
normal burrow
yep taholmes160, i just imagine the archviz features of the game don't involve fps template
wonder if your doing something that isn't already done for you is all
i have no idea personally, but would expect walk throughs be a no brainer for the non-game templates
plush yew
Might well be, I have a lot to learn
cool -- didnt even know there were non game templates
normal burrow
asking in #aec-visualization may prove substantial
normal burrow
admittedly i don't know much about the subject
sonic pagoda
and see if its useful for your walkthrough
plush yew
@sonic pagoda planning to do that
normal burrow
here comes life 🦸♂️
abstract valve
@plush yew for archviz if you use 4.24 I suggest you start using our templates
haha
I'm leaving for lunch right now though

hooray

im following a tutorial on melee combat and im making an animation that puts his sword on his back/puts it in his hand, but i cant get the sword to be in 2 differant places
the link to the tutorial video is here if you need it : https://www.youtube.com/watch?v=jKBAvvJDmMo
stark marsh
what i mean is i need 2 differant positions where the sword exists, his back and his hand
yes and virtus learning academy, hes also another good one
reef lava
mhm
stark marsh
dank pfp 😳
reef lava
I've followed Virtus since back when he was a very small channel
always been a good friend
also
yes
haha
stark marsh
nice, i only got into unreal a few months ago
stark marsh
but about the sword thing though, in the video he makes it in 2 differant places with scene conponents in the viewport
but i just cant get it to work, like my sword only has one position and when i move it for one scene component it just moves the sword for both
its sorta hard to explain but if you watch the video from about 8 minutes onwards i think he does it
does anyone know what i could do?

Hi,I've decided to get in to game development in my free time,I'm graduating in computer science,so I know to program,and I've used blender 3d for about 2-3 years,so I also know how to 3d model,animate etc. My problem is that I'm a bit confused and I don't really know from where and how to start with Unreal Engine.Can anyone give me some suggestions please?
stark marsh
im quite knew to it aswell, but theres tons of tutorials on youtube
reef lava
Start as in what aspect?
stark marsh
thats how ive started learning anyway

If you have an Anim Sequence with a notify close to the very end, when it starts blending out, is it supposed to prevent notifies from firing?
Oh, turns out, anim sequences don't get updated when you reimport them (and they're different) in anim montages. So my new longer anim sequence's length never got reflected in the anim montage.
plush yew
@abstract relic,I've already tried something with unity,but I didn't liked it,made a very awful pong and flappy bird games in it
So I want to restart
reef lava
along with text, the documentation resource as I've linked you does a great job of mixing text with visual and interactable learning. It's also very useful to learn of pretty much or near every feature unreal has to offer, and how to use them, or when to use them.
I started in Unity as well
a long while back
then i began modding other games, some even in Unity
and got to unreal climbing up so to speak
stark marsh
does anyone know how to set two differant locations for my sword to go, like on my character
reef lava
@dim plover nothing should necessarily stop a notifie from firing as long as it's on the anim track where you believe it should be. Although not exactly sure what you mean
and oh
nvm
lol
stark marsh
i need one slot for my hand and one for his back, and i have got an animation that grabs it/puts it back

right. yea, speaking of bugs, I have quite a project breaking one ive been putting up with for quite some time now

What is it, vaguely?
reef lava
ive used ue4 for 5 years...never seen anything like it; but hold up I'll link the answerhub post i created a few days ago
like I said, nothing I've ever come across (and obv using unreal for 5 years you're gonna get the fair share of problems and things you need to solve yourself) has ever been this bad, nor have I any explanation for it

Hey so I have a main menu widget bp with various child widgets in it. And sometimes I get this error: "Error: Blueprint Runtime Error: "Accessed None trying to read property CallFunc_Create_ReturnValue". This is on the "Add to Viewport" function in the image below. It is as if the widget it is trying to add is null, however, it is created just previously. And this error is random. It rarely occurs but sometimes does. Any ideas?
stark marsh
i really dont know how to get this to work like what he does in the video
he has 2 differant sockets for the sword
reef lava
if my map would open I'd honestly try the sword thing myself
but my computer wants to shit on me

fantastic

his back and his hand are both sockets with scene components, and there is an equip and unequip animation

I haven't really I am just considering switching to unreal, and all this blueprint stuff is sort of scaring me away. From a programmer's perspective they look like a nightmare, and they seem pretty much unavoidable in the ecosystem (eg. marketplace). Can a programmer here tell me they are actually good and useful, or am I right to be nervous?
stark marsh
the animation is the thing that i have got working, its just the two differant locations of the sword on my player character which i have no idea how to do

Well what I mean by code faster is in certain circumstances. Basically when I first started 3 years ago, I was super slow with the blueprint system but gradually got faster with it
I still code in c++ obviously
verbal oar
Hooray!
reef lava
right
i personally prefer a combo of both
instances where you'll use c++ , others where you'll utilize bp, simple as said
just gotta learn and know what they are
obsidian lily
ok, re: combo style, can you tell me some circumstances where BPs are good? like, how does the switching work for you?
woeful snow
Um. Well like if I want to program something quick like a component for the player or a widget, or player data overall, I might use BPs. But I would use c++ for tasks like what the player can do or the gamemode. However, when it comes to save game data for servers or just singeplayer, its typically c++
grim ore
well you could code your interface in UMG and BP or you could code it in C++ and slate
void kraken
How do I remove this extra green llayer of texts?
obsidian lily
@grim ore wait, UMG is BP-only?
misty creek
Slate is c++

Any idea how to connect to my steam dedicated servers using IP and Port (Open Level) without using Sessions? I know about NetDrivers and bUseSteamNetworking in DefaultEngine.ini but I still dunno whats the correct way to do it
grim ore
it's not BP only but it would be silly to use the UI layout system in pure code rather than in the editor. technically you can use C++ to do all the UMG stuff but.... why
woeful snow
Anyone have an answer btw for the question I proposed above? I still don't understand the null error.
Its very rare and uncommon as I said
grim ore
obsidian lily
@grim ore yeah, that's what I'm interested in -- why indeed. Right now I can't conceive of what would be bad about the code or what would be good about the BP, even though i believe you when you say it?
grim ore
there is nothing bad about either, the engine is designed to use both
so you learn the engine, learn how it works, learn what is supposed to be done how, and profit
you can force yourself to use one or the other but the optimal way is both if you can
rigging up an animation blueprint?.... blueprint. doing some heavy math loops? c++. setting up a UI? UMG. etc.
obsidian lily
ok, I see
and what abotu the VCS question before? How are blueprints saved on the filesystem? what do they look like in git?
grim ore
I Personally use BP as much as I can because It's much faster for me (no need to reference the API or remember * & etc.)
Blueprints are data so no real diffing. there is BP Diff in the engine but it's wonky
in the end the general practice is do your C++ stuff when you want to do C++ stuff, expose it to BP to hook it all together visually if you want or to let your designers who can't code design stuff and make a game in the end
obsidian lily
data, as in stored as binary so there's no text to diff meaningfully?
grim ore
yep binary, not text
obsidian lily
that's pretty bad
it makes me queasy to think of substantial connective tissue in a complex piece of software, just hidden from VCS
like pull requests and code review
and testing. I suspect it's probably fine in practice
but call me a dinosaur, it definitely doesn't jive with my coding habits to date
grim ore
there is automation testing in the engine itself and you can do it with blueprints if you want
code review in BP is no different than code review in text, you just see it in pretty boxes 😛
its a different work flow for sure
obsidian lily
yeah that parts made me hopeful -- I have a whole spreadsheet with questions to answer about unreal, and checkboxes where the answer "this will be fine" and testing is one of the checkboxes 🙂
grim ore
I mean a function that takes in data , does stuff, and outputs data is going to work the same in BP or text code you just have to grok it differently
the primary thing to remember if you have this question is blueprints are just C++ code on the back end exposed in a pretty picture to the front end
obsidian lily
that's what I keep reading
but also that they are stored din binary, and like 10x slower
obsidian lily
if it were literally the case that BP graphs were just natively represented as straight-forward, generated c++ then I'd be fine
grim ore
it's all relative in terms of BP being slower than C++. In the end if you optimize that will not be an issue
obsidian lily
@grim ore yeah, I've had this conversation with myself too. My usual answer is "I'm switching the beauty and ease of C# in large part for the performance gains, how sad will it be if I pay the price and don't get the benefit?"
grim ore
and technically there is support for BP saved as text assets (the engine just doesnt read them lol) and you can technically copy/paste BP graphs into text. The issue is they don't save as text and probably never will to be honest.
frank escarp
BP tick is more than 10x slower
measured about 100 times slower or more
to give a reference. 100 BP tickers will waste 1 ms on consoles
btw, 100% overhead, tick connected to nothing
obsidian lily
fuh -- seriously, what could it possibly be doing under the hood that causes that? some kind of asinine marshaling scheme?
frank escarp
different types of overheads in a bunch of places
just do not use blueprint tick at all
use blueprint for event based stuff, not stuff that runs every frame
and specially not for anything that loops more than 20 times
blueprint has a "fixed" overhead per-node. If you have math loops, the overhead of BPs will be much bigger than the calculation itself
other than those gotchas, you can use BP
just remember that they are a script language
use it to extend stuff and do high level stuff, not core logic
fossil socket
don't ya just love it when you click a UE4 link on google then it logs you out of your epic account for some reason and then redirects you to a completely unrelated page
grim ore
Spend a bit of time making a small project in UE4 trying out BP and C++, remake something you have done in Unity to compare if possible and just see what happens.
obsidian lily
I mean, my original thought when I started looking into this was that I'd just avoid them, but the ecosystem is pretty dominated by them :/ Like, you'd be hard pressed dto find a tutorial or marketplace asset that isn't just BPs
frank escarp
because distributing c++ plugins is much more of a nightmare
so only serious stuff gets distributed as c++ plugins
obsidian lily
yeah @grim ore I think I'll need to
frank escarp
but anyway
normal burrow
its interesting that prebuilt binaries are a thing on mp
obsidian lily
I believe you
frank escarp
there are some very nice things on the cpp plugins land tho
pretty much all cases of marketplace "game logic" stuff in BPs is garbage
mostly because you shouldnt be implementing such things on pure BP to begin with
normal burrow
idk vblanco
if the person is using pure bp in their game they might be putting a lot on the exposing of native from plugin land
dim plover
It is unusually hard to read BP marketplace stuff.
I bought a couple of settings menu stuff, all BP, couldn't follow any of it.
On another note, if anyone wants to make a settings menu done mostly in C++, I'm sure there's quite a bit of interest in it. Might be worth it. 💰
obsidian lily
speaking of plugins -- one thing I'm still trying to figure out is pathfinding. In unity there is basically nothing, but there's an excellent project called a* pathfinding project by this guy who's been at it for years. It's a great package. when I looked into it in unreal it seems confusing. My impression is that there is some kind of native pathfinding in unreal, but also that people write their own which tells me it's probably limited, but I can't find any details
and most importantly, I can't figure out if there's a plugin that already exists that tries to be comprehensive like APP tries to be
grim ore
There is a navigation system in UE4 out of the box and technically A* in the engine just not exposed.
dim plover
There's also EQS, which you may want to look at.
obsidian lily
APP is poorly named -- I thnink it started as an A* implementation, but actually now it's a big system with a lot of options
grim ore
the basics for navigation itself are built in. areas to move on, obstacles to avoid, etc.
obsidian lily
dynamic, too, I assume?
@dim plover -- this? https://docs.unrealengine.com/en-US/Engine/ArtificialIntelligence/EQS/index.html
grim ore
depending on the goal yes, I know people bitch about it in "large" worlds but I think its a learning curve for that one
Fortnite is fairly large and has bots using UE4 so thats about as well as I could say it works for sure
native adder
How does one make a character rotate using blueprints?
obsidian lily
my use case is basically 2 different things: one is smaller areas with fairly complex geometry (including bridges and the like), and one where for large areas that are significantly for simple
think of like navigating a landscape over distances, then navigating a town
grim ore
@native adder if you are using a Character you can set the control rotation
slap down a nav mesh over the terrain you want it to walk on, block anything you dont want it to walk on, and tell it to move lol
native adder
Its a 2d frictionless enviroment
grim ore
a to b navigation is pretty simple, the EQS system is more for choosing what to do rather than moving itself
native adder
And the desired effect is the character rotates to the mouse
grim ore
well i dont know how you are moving the character itself but there is find look at rotation if you want to find the rotation from A -> B
obsidian lily
yeah it sounds coo. Although I do worry about details -- what about ladders or other "jump" type connections? What about dynamic geometry, eg. the player places stairs in a new arbitrary location?
grim ore
there are nav links for going up and down, ladders are special case like in anything
native adder
@grim ore The movement is by a basic clicking system
Press left to add speed and momentum
grim ore
how do you turn it now? or does it not turn at all? can you rotate it now with keys or mouse
native adder
Not turn at all
dim plover
There are nav modifiers that apparently able to support stuff like that. Dynamic geometry is also supported more or less out of the box.
The only thing it straight up can't do is flying stuff. No navigation info in the air.
grim ore
then you can probably just rotate the mesh, otherwise if this is a Character class you can set the control rotation. You can use the find look at rotation node to find the correct rotation to use.
obsidian lily
this all sounds great. I may need flying down the road for some kind of mob, but whatever, I'll burn that bridge when I come to it
native adder
Will do

Are planar reflections totally disabled for mobile platforms? Or is there an override checkbox hiding somewhere that disables them on mobile by default? I currently see blackness where there should be reflections 🧐
obsidian lily
the main thing is people walking around, which it sounds like I'm good on
grim ore
yeah walking around is no problem. You can find many a tutorial on that basic AI lol
even ones that handle doors and remaking the nav mesh as needed
grim ore
you are just going to have to go play with it for a bit, even if it hits all the checks it still might not work
obsidian lily
actually, while I have you: what do you think I might be fucked by that I don't yet know about? Like what would I put on my spreadsheet if II already knew what I don't currently know about the pitfalls of unreal?
grim ore
Every engine has plusses and minuses, your project should dictate what to use
like a mobile 2d game multi platform and using ads I might avoid UE4 if I wanted to knock it out quickly
a basic Multiplayer FPS, I would choose UE4
an AR experience that needs the latest SDK, I might go with Unity and Vuforia
obsidian lily
it's neither, but in terms of scope and capability, unreal is fine, and almost certainly better than unity
grim ore
I don't think either is better, they just do things they do
obsidian lily
I have a prototype in unity which just can't hold up, performance-wise, even though I've tried pretty hard
dim plover
a basic Multiplayer FPS, I would choose UE4
Are you implying that you would pick something else for an advanced multiplayer FPS? 😄
grim ore
maybe lol. I know a basic MP FPS would be like drop in assets and bam it works in UE4 lol
like a more advanced MP FPS I might lean towards Unity just due to them having more services I might need as epic is still ramping those up
obsidian lily
are there any obvious must-have assets for something like that?
grim ore
Unity really has a quite nice set of services they offer their users and Epic is just slowly catching up
obsidian lily
like is there a "everyone uses this" kind of character controller or something?
dim plover
What type of services? Like... Gamelift support sort of things?
No, there aren't really any mandatory third-party plugin stuff, really much at all.
grim ore
yeah. ads, analytics, cloud supports, etc.
nothing you cant do in UE4 just not out of the box like in Unity
but then again Unity literally has no official Networking layer right now so....
obsidian lily
yeah I guess that's true, but I also was surprised when you wrote that
because when I think of unity I think "well, this is going to have to be custom..." because basically nothing works
like networked multiplayer -- sure... except not, you have to roll your own
even terrain is like... well, fine to prototype, but good luck actually using it in a real game
grim ore
yep it's a global picture type thing. What can I get out of the box from this engine, what do I have to roll myself, what can I purchase, etc.
Unity is catching up to UE for some of that quality of life stuff, while UE is catching up to Unity for some of that bonus stuff
obsidian lily
yeah, agreed
normal burrow
blasphemy
grim ore
at some point Unity Engine will be born
