there is a way to duplicate the part that is looking good, mirror it and use that?

I am attaching it to the metahuman, using the blueprint of it to attach the mesh to the head joint

Your specs should be okay. I'm not versed in the nitty gritty of unreal, so I can't help beyond that. Could be so many reasons from a bad UE update, to drivers, to something else on your machine taking up resources, etc.

Hey, can anyone explain what those values are? (I changed them to fix the bouncing ball on a flat surface issue, but I dont understand what they are)

So I duplicated a spark from the starter pack and I’m trying to change the color for my project

#

How do I do that?

#

My project is version 4.27

Hello, I have a question hopefully it's simple. I'm using an alpha to mask out something, but the mask is varied, has grays etc so that some parts will blend with the background. However, when applied to my asset only the absolute blacks and white work. So there is 0 blending.

#

Is there a way I can get those grays blend

worn pewter
cloud pagoda
#

(also, when I look at my mask texture it does have all the grays etc)

fierce tulip
#

are you using translucency or mask blending mode?

quartz ore
# worn pewter Can you show me where exactly?

I mean, I don't have the editor open with that asset so not really lol. You can probably search for 'spark' in the content browser. Then look for the material asset using the filters if you need to.

cloud pagoda
fierce tulip
#

well, there is your problem. its either on or off

#

you can try ditherAA node to fake it a little, but thats about it

cloud pagoda
#

I just switched to translucent mode and its still the same

fierce tulip
#

I doubt that, show the material.

cloud pagoda
#

Is there a way to make it exactly the same as it is in substance?

#

Sure, one sec

fierce tulip
#

i dont use substance, so no idea.

#

I need to scoot in a few seconds, but im sure once people see the mat they can help out.

cloud pagoda
#

Sorry, I'm dumb. The instance was overwriting the blend mode

#

It seems better now. The lighting just changed drastically but I think I might be able to fix it

#

Thank you

fierce tulip
#

good luck on fixing it :) take care!

#

hello everyone! I have a question about confining particles to spawn in a fixed boundary using the cascade system. Does anyone have an idea on how to do that?

fierce tulip
#

what kind of fixed boundary?

weary verge
#

So my particle is bubbles

#

and I want to confine it to the cauldron in my scene

#

hence the fixed boundary

#

it's currently spawning all over my scene

#

and I want to confine it to just that space

fierce tulip
#

cylinder location, make it flat, scale it to about the size of the cauldron, minus the radius of the bubble-size

weary verge
#

so cylinder location as in the actual mesh in my scene?

fierce tulip
#

no, there is a location module in cascade called cylinder

#

that makes it spawn particles inside a cyl.

grim tendon
#

Does anyone know: is the act of toggling collision expensive? Like if i have an object that i want to enable overlap events for a small window then disable them again, is that an expensive operation? am i better off just leaving overlap events on and filtering them in an event, or would it be more efficient to disable collision in the physics engine?

weary verge
#

okay got the cylinder module and you said to make the cylinder flat

#

as in scale it in editor yes?

fierce tulip
#

there are size options in the module

weary verge
#

so the start location

#

where the constant values are

fierce tulip
#

no, the radius

#

that changes the radius of the cylinder.

#

and a height of 1

#

the tiny arrows are drop-downs to expose more options

weary verge
#

So when I change the value of the radius

#

It seems I can only spawn them in one axis

fierce tulip
#

if its a cauldron, the height axis is Z (z=up in unreal)

#

unless your cauldron is mounted sideways on a wall :p

weary verge
#

Haha it’s not I promise!

#

😂

#

Okay that seemed to work quite well!!!

fierce tulip
#

dont think you need to enable velocity unless you want the bubbles to move around

weary verge
#

I wasn’t sure about jt

#

It*

#

Because generally when anything is bubbling they don’t rise

#

Unless your under water

#

So I think logically giving it velocity wouldn’t make sense

fierce tulip
#

assuming its like hot boiling bubbles

#

they are only on the surface

#

anyways, i need to head off. good luck!

weary verge
#

Yea hot boiling bubbles!

#

Thank you so very much!!!! @fierce tulip

#

You saved me so much time, greatly appreciated!! 🥳🎉

Does anyone know the formula to calculate whether the player is looking at something?

#

Thought it would be similar to this but this doesnt quite work

oak patio
#

cant you just use a line trace

robust marten
oak patio
#

i mean you should still just use a line trace

robust marten
#

that isnt what i asked for though. I'd rather use a formula to check per instance rather than use yet another constant line trace

oak patio
#

well then just get the angle between the two things, if it's near 0 you should be looking at it

true ridge
#

Is there a list if differences between building for development and building for shipping? Things like PrintString not being included in shipping builds.

oak patio
#

but again i would jsut use a line trace

#

do everything in one line trace

#

line traces are cheap

For some reason one of my input actions works for development builds, but doesn't for shipping. 😅

Does unreal have the ability to save text files or some for of note files so that when i open a project later down my timeline, i can reread the various adjustments I have done?
or is my only option saving an external text devlog or video devlog?

oak patio
#

use git and read your commit log

paper cobalt
#

like source control? or just git?
ive been needing to work in this pipeline

real heath
#

Any source control will do that. Good commit messages are amazing for reviewing work and rolling back changes

#

The benefits from it are directly proportional to how well you write your commit messages and break up your commits

#

Committing a whole day of work, with 50-100 files with a comment of "improved level" is not that helpful

#

Commiting smaller sets of files with "improved hero statue material and reduced drawcalls" and "redid lighting to be more moody" are much more helpful

hi, trying to create a simple attacking enemy but i have an infinite loop that just kills the editor, any ides of how to fix this?

unknown.png
#

Ue4 says that the first "can attack" that is set to true is the culprit

#

is there a way to limit tis trigger to once per call?

#

to be fairm i not even sure why its bad that the loop is continuous since i want it to be ticking as true as long as the player is in the attack range

real heath
#

that will mean that instead of immediately and repeatedly calling play montage again, it will only loop after the montage has finished, which could be a few seconds

#

That default execution pin executes immediately

ah i see

#

it worked

im a dumbass and missed that, i tought it does it like that by default 😦

#

I've investigated pretty much the entire internet (including discord searchbar), to gain information about whether CSV files can be localized.

#

However alongside these tutorials, is a ton of posts saying it doesn't work 😆

#

Does anyone have any insight into whether the Localization Dashboard (or UAT) can generate loc files (locres, archive, etc) based on a csv file loaded as StringTable using LOCTABLE_FROMFILE_GAME

#
  1. The CSV file is 100% loaded, because I can select the localization in my assets no problem.
  2. The Localization Dashboard returns no results
  3. When I make a StringTable asset and "import from CSV" I get two tables with the same keys (duh), and Localization Dashboard only picks up the binary StringTable.
#

I think the issue is the string-table created using this Macro is sorta "in memory" and therefor not getting picked up by localization?

@pure marsh Answering here to not flood introductions. If you scroll around in here, you'll notice a lot of people have a lot of issues with UE5, it's not very stable as of now. I'd say you should start in UE4 unless you're specifically trying to take advantage of the new UE5 features. You can build everything in UE4, and down the line, when UE5 is more stable, move your project over pretty hassle-free.

Hey guys, working on a ADS system. I want to switch Camera when i reload so u can see the reload animation. How do i make my Reload input stop the ADS camera from working, so that it switches automatically even if I'm still holding RMB?

get a reference to that object first

modest trench

get a reference to the player pawn with get player pawn ¯_(ツ)_/¯

or... maybe do this logic on something that isn't just this enemy unless it is exclusive to this enemy

valid inlet

luckly this is a small project so there is only one enemy

fresh pulsar
#

I still need help btw tryina get the player to shoot towards the mouse cursor

modest trench
#

break down the problem into two main things

#

1: spawning a bullet when you click

#

2: making that bullet in the right spot and sending it forwards

thin tendon
#

@valid inlet Passing variables, references and information is a concept you need to get familiar with. The cast node is asking for a reference to your player. There are a a few ways to this(get player character etc). But without telling the cast which player. It won't work because it could be any player. If it were an object reference it could be any object in the game(potentially thousands). But learning to pass information and references clearly is important. Because if done right you don't have to keep looping over your world and trying to find actors.

modest trench
#

if you are like me the second is probably the confusing part

fresh pulsar
#

I know the logic of what I'm doing I just don't understand how to translate that into unreal's nodes @modest trench

modest trench
#

yeah, of course

#

so, for starters what kind of bullets are these?

#

hitscan or actually simulated?

valid inlet

im an absolute dumbass 😢

#

i forgot i have to pin the white pin as well in order for a node to work

unknown.png
#

its all good now

fresh pulsar
#

At the moment

modest trench
#

it then uses the rotation of the camera for the bullet rotation

fresh pulsar
#

Btw I'm working in 2d

modest trench
#

it uses a vector rotated by the camera rotation to offset the gun barrel location a bit too

#

oh, in that case you just need to figure out which direction to fire it in

#

and then add an offset to the player's current location

#

based on where you want the bullet to appear relative to them

#

you probably want some sort of rotation turned into a vector and added to said player location vector

#

gotta go

fresh pulsar
#

I'm not sure what the node is that turns the mouse location on viewport into a world location @modest trench

#

I forgot..

fresh pulsar
#

I need help from someone else who can be more thorough lol cuz I don't get it at all

modest trench

if you are using a truly 2d world you could just take only the forward/back and height values of the coordinate and set the depth to be where your game actually is in the 3d space

but if it's regular 3d non-ortho projected I'm not sure off the top of my head how to get the intersection between the mouse direction and the plane of the 2d world

Heya 👋
Does anyone know if there is a metadata specifier for deprecated uassets like textures, animations etc.? I can find docs about setting functions, variables, custom events and blueprint classes to deprecated and specifying a DeprecationMessage but would this be possible for other assets (like textures) as well?

#

Hoping for some kind of built-in support for this🤞

drowsy snow
spice ruin
#

Maybe add a redirector.

deft sparrow
#

Ah unfortunate but thanks for the answer :D

#

Might be a dumb question but could you clarify on the redirector part? Assuming you mean that I could just delete/replace the refs for the deprecated asset and it creates a redirector to the other one?

drowsy snow

Multiply the forward vector of the rotation by how far it should be from the center

I'm I'm bed so I can't show the nodes, sorry

fresh pulsar
#

Aww damnit

#

Is there nobody else who can help

modest trench
#

Try dragging the rotation value and typing "forward"

#

The multiply that vector with a multiply node that uses a vector * float

#

Where the float is like 200.0f which would be 2 meters, for example

#

The resulting vector then is added to the center of the player

#

To get the spawn location of the bullet

fresh pulsar
#

I then need it to constantly move in one direction based off of that angle

modest trench
#

The bullet itself can either be pushed with physics or just move itself forward when it spawns

#

Is this homework?

Hello can anyone please help, I'm making a simple wind trail particle effect and I've been trying to fix this issue for a while, with no success

fresh pulsar
cloud pagoda
#

As you can see, at random moments, a trail will completely glitch out by snapping back to the start point?

fresh pulsar
#

You can't really get in contact with the IT department as a student, best i can do is ask my teacher to talk to them

modest trench
#

That's your best bet, I have had to do that at school a few times

fresh pulsar
#

Also I'm at college

#

Not school

#

Lol

modest trench
#

Very fancy distinction

fresh pulsar
#

I mean but college and school are 2 different things

#

Nothing to do with fanciness lol

#

Okay I will be back when I'm home and have my project open

modest trench
#

As long as we get part credit I guess

fresh pulsar

genrally the point needs to live longer than the trail. but --generally-- we just spawn a curvemesh (long thin strip shaped mesh) and pan a sprite along it. its cheaper as well.

#

There's no credits section on a college hand in lol

Just kidding, but send my report card to Canada soon

#

We are a vassal state so it should work out

fresh pulsar

#

you'll get used to these jokers :p

modest trench
#

Sorry, I am joking there

#

If someone says something that stupid you can generally assume they are kidding

fresh pulsar
#

Also I'm not sure I appreciate it when I'm stressed out and asking for serious help lol..

modest trench
#

Sorry my free help isn't awesome enough I guess

fresh pulsar
fierce tulip
#

we mods still appreciate it if helpfulness is at least 10:1 memeness though.

#

(cpp and lounge excluded?)

modest trench
#

Serious advice: do some basic unreal courses at home that are about using BP to make gameplay

fresh pulsar
modest trench
#

It's better than asking us every step of the way

#

Oh, sweet

#

Godspeed then dude

fresh pulsar
#

I'm losing it over here.. fr

#

brb anyway I'm at home now I need to go boot up the project

modest trench
#

Don't feel bad about asking the math stuff though, that stuff is no joke

#

You can find me asking the same question 5 years ago in here haha

fresh pulsar
#

I don't have much beyond a school level understanding of math I'm really bad at it

modest trench
#

So am I, I just collect shorthand rules for how to get the results I want

#

You just mix and match simple steps

#

Remember you can debug draw stuff along the way to see the vales quickly

fresh pulsar
#

I just let certain nodes handle the math for me without having to think about it lol

#

Like finterpto

modest trench
#

There are lots built in but they can't account for everything

cloud pagoda
fresh pulsar
modest trench
#

That's the spirit

fierce tulip
#

@cloud pagoda oh, idea. you could send a kill-event from the point to the trail to kill it off.

fresh pulsar
#

At least im not working in a written coding language, could be worse

cloud pagoda
#

Also how would I do that? Sorry this is my first time using particle fx

fierce tulip
#

hmm, prolly die.
as for the curve-mesh: https://realtimevfx.fandom.com/wiki/Curvemesh
and the unreal docs go over all the cascade modules.

RealtimeVFX Wiki
Curvemesh

Keywords: Soulercoaster, Splinemesh, Curvesweep, Zoomie, Geostrip, Swipe, Swoosh.
A mesh consisting of quads (or other shape) extruded along a curve. The UVs are then laid out in a way that if you scroll a texture along the mesh it looks like the texture is following the path of the mesh.

A nice tutorial for creating curvemeshes by Russell Bake...

fresh pulsar
#

Seriously though in the future I think I want to avoid using unreal wherever possible it's driving me insane

cloud pagoda
#

I prefer generating them in Unreal because they're very basic almost straight lines

#

Do I add the kill attribute to trail? And what properties

modest trench
#

Other game engines will be a bit easier for 2d games

fierce tulip
#

curvemeshes are generally cheaper than ribbons though. ¯_(ツ)_/¯

modest trench
#

Really?

cloud pagoda
#

It's not for a game, it's a fairly small render scene

modest trench
#

I assumed ribbons were meshes :0

fresh pulsar
fierce tulip
#

how to explain them, i think its more stretchy sprite connected to next stretchy sprite.

modest trench
#

With the stretch defined by shader math rather than a poly?

fierce tulip
#

but needs to generate em on the fly

modest trench
#

Interesting

cloud pagoda
#

So how do I set up the kill switch in this case

fresh pulsar
#

Biggest win I've had when working with unreal is managing to resist the urge to light my pc on fire fr

fierce tulip
cloud pagoda
#

More specifically, where do I place it? In point or trail

fierce tulip
#

you need a generator in the point, receiver in the trail

cloud pagoda
#

Oh ok

#

I'll try to do that, thanks for the help

fresh pulsar
#

You know what I'm at home now outside of college time i think I'll just decide nope not dealing with unreal anymore today I'll ask for help with this tomorrow

fierce tulip
#

or, fix it now and have the xylon of tomorrow stress-free :p

Hello all, any good tutorial suggestion?

fierce tulip
#

the ones in the pinned messages :)

fresh pulsar
#

okay project downloaded

#

anyway the code isn't done but I'm working on it

unknown.png
#

I'm gonna set actor rotation but then how do I get it to like move forward based on that rotation? hm

#

That also isn't gonna fix the problem of it spawning in the player when I need it to spawn away from them but I also need to spawn it away from them based on the placement of the mouse cursor, in general just top down shooter mechanics

modest trench
#

Add this component to your projectile bp

#

I think it should do what you want

#

Or at least save some work

How to hide a clump of foliage objects to be unhided later?

fresh pulsar
modest trench
#

That's not a bad idea lol

fresh pulsar
modest trench
#

That list of class members is kinda just autogenerated

#

Based off the source code comments

fresh pulsar
#

Always is good to stay on top of changes especially in the games industry, I'd get UE5

fallow jackal
#

wait for unreal engine 6 and come back

modest trench
#

95% of tutorial content for 4 will still be relevant to 5

#

It's not a huge change code wise

fresh pulsar
#

UE5 doesn't seem that much different from 4 tbh

#

Huh.. I have a delay set but it's doing bugger all it's still rapid firing like a machine gun lol @modest trench

modest trench
#

A delay.. where?

fresh pulsar
#

it's not waiting for the delay to complete before refiring the command

modest trench
#

And called how many times?

fresh pulsar
#

hm

fresh pulsar
modest trench
#

Show code, I can't understand what you mean

fresh pulsar
#

idk where else I'd put the delay

modest trench
#

That delay delays nothing at all

fresh pulsar
modest trench
#

You may want that delay to set a value that controls if a bullet is fired

fresh pulsar
#

apparently not

modest trench
#

Or to use a timer

fresh pulsar
modest trench
#

This channel is amazing, would recommend you use this to learn BP quickly

#

If you have a specific node in mind he's probably covered it

fresh pulsar
#

this should work right @modest trench

unknown.png
#

even if it can activate multiple times constantly this should stop it

#

Also I'll make the delay assigned to a variable called fire rate in-case I wanna alter the rate of fire dynamically for any reason

drowsy snow
#

Depends on your project needs and how far it is in development

fresh pulsar
#

Yep this code works just tested it

#

For once I figured out how to do something myself, nice

modest trench
#

you might want to set that delay node to have a specific value you set elsewhere too

fresh pulsar
modest trench
#

the level viewport will be an instance

#

change the transform in the BP or the transform you spawn it with

fresh pulsar
#

lol

#

I can't change it in the level viewport because I have to input something while the game is playing to spawn it

#

so umm... any clue what to do? @modest trench

#

since changing the transform in the blueprint does approximately nothing

modest trench
#

without seeing the projectile BP I have no idea

valid inlet
#

where can i find my specific level name?

fresh pulsar
fresh pulsar
#

it's scaled to 0.1 but that doesn't change anythin

modest trench
#

or... maybe it needs to have a scenecomponent parent?

#

I never touch paper2d stuff

#

so I'm kinda clueless here

fresh pulsar
#

no option

#

only the papersprite does

modest trench
#

try adding a scenecomponent component

#

that acts as the root

fresh pulsar
modest trench
#

show the scenecomponent hierarchy

fresh pulsar
#

Oh I figured out the problem, it's the initial transform over-riding whatever I set the transform to in blueprint @modest trench

#

now to go mess around with the whole projectile component stuff

modest trench
#

ah, nice

#

just keep in mind that scale and transform etc need to be relative to... something to actually do anything in a BP

#

so most BPs will have a scene root so they can mess with the offset without changing the center of the entire BP actor

#

or just fix the offset in the actual asset angery_cat

Unless you desperately need a certain feature of 5.0, I'd say you stick with ue4

# rich kayak thats bad.

4.27 will probably receive various bug fixes over the next few years. If Epic devoted large enough portions of their team to develop new features for UE4, large enough to warrant 4.28, while UE5 continues to have stability and usability issues, that's really Bad. It only makes sense to continue moving forward with a new product.

Very dumb question

#

I have ue 4.27 installed on my external ssd, and now I'm on another pc - I just installed the epic games launcher but how do I "set" the unreal folder so that my ue 4.27 appears in the launcher?

If I try to install it and point it at the folder it says that it must be empty

Wow now we definitely want to help lol

#

Your best bet and easiest method is to simply reinstall your engine with the new file path.

plush yew
#

Sorry, people that just wants to shove an useless answer on you are irritating.

#

Perfect, thank you @thin tendon

#

See? Nice and easy.

drowsy snow
#

Right, ladies?

plush yew
#

Yep, looks like it.

thin tendon
#

There would no doubt be a config file somewhere. But if re-installing is an option. Then its the least hassle.

modest trench
#

The engine creates a registry folder too

#

Which I believe sets the guid for the uproject association

drowsy snow
#

For longer term like internal drive, or after reinstalling the launcher or the Windows, then tricking the launcher would do.

drowsy snow
modest trench
#

Really? Maybe only for source builds then

drowsy snow
#

You can't just run UE4Editor.exe and call it a day

#

/s

modest trench
#

Oh lol

plush yew
#

Obviously if that was all I needed I wouldn't have asked in the first place

modest trench
#

The uproject guid can also be set as a file association but that might not affect the launcher either

#

I'm actually struggling to get it to play nice in a source build

drowsy snow
#

I mean, my idea is to set aside existing copy of the engine, and attempt to install again through the launcher. Then once it starts downloading, pause the download, move the existing engine files to the install directory, and then resume to let the launcher verifying the files

modest trench
#

It wants to change the guid every time from source control

#

Oh yeah, the classic game download strat

drowsy snow
#

But eh, I found it faster to just make a shortcut to UE4Editor.exe and call it a day

#

Especially considering the engine located in external drive, which the letter can change the moment you plug it in again

plush yew
#

That's how I did it in the end

#

Thankfully both pc and the drive are mine so I set a static letter for the external drive

drowsy snow
#

Also source build will never appear in the launcher so you gotta get used to launching from UE4Editor.exe directly

modest trench
#

I think it can appear as a version to add marketplace assets to

#

hence the registry stuff

plush yew
#

Yep

drowsy snow
modest trench
#

yeah, having a binary version sitting around is definitely a good idea

#

why can't we just download assets without an engine ;___;

drowsy snow
#

Wait, you can't? I thought that's only applied to plugins

modest trench
#

pretty sure you need the version installed to get them

#

I might be wrong

drowsy snow
#

I don't think so. For assets, it's much more lenient, setting closest engine version for a project and it will download the asset and add to the project, even if the last compatible version is older.

modest trench
#

ah, yeah

#

I think you are right

drowsy snow
#

Code Plugins, however, do require installed vanilla launcher build to be downloadable

Is there a way to debug garbage collection? I'm having big stutters and freezes due to garbage collection but I have no idea WHAT objects or actors are causing the hitches.

#

I know it's garbage collection because when I change the garbage collection time the stutters happen at the exact time intervals I set. stat startfile recordings also show garbage collection as the big spikes, but I can't find any pointer as to what items are getting collected that cause the hitch. Weird thing is that my actor count never changes. But somehow the GC is still doing SOMETHING that causes hitching. I'm guessing setting flags for objects still referenced or something?

#

For games with large amounts of spawned actors and stuff I'd hope garbage collection debugging exists? I mean how can you make such a game without proper GC debugging?

You are hidin the widget the code is executed in

fresh pulsar
#

like the visual and code component for it, want it to all get hidden

#

for as long as well, the game is active

#

it's pretty much just a start screen with a play button

short plaza
#

You are opening a level, that means everything is killed and reconstructed on level loaded. Means the widget your triggered the button in does not exist anymore

#

try removing the OpenLevel node

#

that should hide the interface

when the button's pressed I want it to load that new level and I don't want the start menu to reappear

Remove the OpenLevel node. Does the menu disapear?

When you load the other level, you respawn the interface

I just need the menu in a seperate level so the player can't just run to their death before they even start the game

so I like.. I need a way to disable this menu for the rest of the duration of the game once you press it once

You respawn the interface when loading the other level. Just don't spawn the interface again

how do I... make it not spawn again?

short plaza
short plaza

ig

#

thing is I just wanna get rid of this widget cuz the hud has other important widgets like player health

short plaza
#

You can spawn the main menu in the level blueprint of the main menu level

fresh pulsar
#

I dont even know how to get into level blueprints tbh double clicking them just opens the level

short plaza
#

then you don't get it spawned in the other levels by spawning it from GameMode and related blueprints (GameState/HUD/Player/..)

#

TopBar->Blueprints->OpenLevelBlueprint

#

LevelBlueprints can also directly reference instances in the level. See some tutorials

fresh pulsar
#

h... how on earth do I put a widget in the level blueprint it only has a node view

short plaza
#

CreateWidget?

fresh pulsar
#

ah

short plaza
#

Like you already did?

fresh pulsar
#

Okay so yeah I've done all that jazz @short plaza

#

Err it's not creating anything

short plaza
#

CreateWidget->AddToViewport

#

How did you do it before?!?!

fresh pulsar
#

I don't know but it's working now @short plaza

#

Although.. the hud is showing up over the main menu, not good

short plaza
#

Then don't spawn the hud?

fresh pulsar
#

For some reason..

short plaza
#

I thing you do most of the stuff via the GameMode and related blueprints? Use a different game mode for the MainMenu

fresh pulsar
#

..... what

#

?

#

Btw it has no event graph

#

Do you use a template Project?

You should realy check out some basic tutorials of Unreal and the structure of Blueprint. Classes Like GameMode, GameState, PlayerPawn. Then understand how the template does stuff.

Anybody noticed jittery rotation when using the DefaultPawn? Rotation is very smooth in the editor, but PIE with DefaultPawn feels like the rotation is rasterized

tall sorrel
#

I think this is where this should go, but I am not sure
However, I have been searching for a way to un-instance an instanced mesh, and like have it as a copy instead at run time
For instance you are in a forest and all the foliage is instanced, and you walk up to a tree to start chopping it down, and press the button and it fires a line trace, then the tree somehow switches to an un-instanced version, or even an actor version potentially, so then it can fall over and de-spawn

I think a while ago I saw somewhere that a plugin does this, but I cant find anything on it since, and I am pretty sure there is a way to do this since I think AAA games probably do this, and it sounds optimized, but I don't have AAA experience so I am very unsure.

edit: also, although I'm not asking a c++ question, I do use c++ and blueprints, so I can get it doen in both if it can be done in one or the other.

fresh pulsar
#

@short plaza I was able to do it by checking in the code that spawns the hud if the level name matches the main menu level, if so just don't spawn it

short plaza
tall sorrel
# fresh pulsar any clue why this aint workin?

why you doing that on tick with a do once reset if button pressed is false?
you know buttons have a function literally called IsPressed, that gets called when it is pressed, just use that bro. Also why are you setting MainMenuConstructed to true after the branch? if it made it through the branch that means it was true, just some tips

tall sorrel
short plaza
#

Don't know how that stuff works, but I assume he uses a Blueprint replicate for the static mesh. Like there is a map somewhere where you need to map the static mesh to a blueprint. So the static mesh can be removed from the HierarchicalInstacedStaticMesh used for foliage and be replaced

#

Though you already can spawn Blueprints as Foliage

tall sorrel
#

but they are actors, and thats heavy on the performance, and you cant have them in a material, so useless for bushes or flowers

Is the Collision of a StaticMesh that is used as a SplineMesh supposed to update visually?

#

Because it seems to be:

  1. Stuck at 0,0,0
  2. Not scale to match the visual part of the mesh
#

This is on 4.26

#

I searched around a lot and tried some checkboxes, but this seems odd

#

It seems to update fine during runtime, when pressing play, even though when ejecting the collision is still wrong :<

Your faces are inverted, when you export a mesh make sure you have correct face orientation in your 3D editor before exporting.
Blender has a tool you can use to check, see the overlays dropdown in blender 3d viewport (top right), and check off face orientation

unknown.png
#

Now the fix, select all faces of your mesh in edit mode and hit Shift+N, the default hotkey for recalculating normals to face outside.
Basically any face you want visible and is not two-sided should be colored blue in this overlay.

#

Alternatively, when modelling your props, turn on backface culling in your viewport so that only front faces are visible

hey guys can i ask beginner questions here?

real heath
#

Ofcourse

plush yew
#

ok but please don't yell at me...

#

ahhh what's a target xD i guess is the objekt the node represents but why does Set Static Mesh need a New Mesh and a Target

real heath
#

So typically a node is a function of a class or object. Target is the instance that yoh want to perform the function on. For example SetActorLocation is a function of actor. Let's say you want to move a cube and you use a SetActorLocation node, the target for that would be the cube you want to move.

#

So in your case target is what object you want to set that mesh on

plush yew
#

does the mesh get set on the target or the target set on the mesh

real heath
#

Mesh gets set on the target. The target is what you are executing the node on

#

You are operating on that target

aha great thanks i looked for an answer for like 3 hrs on that, can i ask another question?

Sorry, 1 question only

hello i have a problem, i made this in the thirdpersoncharacter bp to shoot a projectile in the direction of the camera, but sometime it doesnt shoot toward the camera but in random direction, especially when im moving the character in every direction while shooting, any help?

real heath
#

Fix can be change collision channels or make it so it spawns a little in front of your character

surreal vector
#

all the collisions of the projectile are on overlap and the projectile has "should bounce" unticked

#

when i connect set static mesh to Create Dynamic Material Instance, it still needs a Target, i do use the same Target as in Set Static Mesh. But i just wanted to understand why Create Dynamic Material Instance needs again a new Target.

real heath
plush yew
#

AHHHH thanks

real heath
#

The reason it needs a target esch time is becsuse computers are dumb and can't guess this stuff.

plush yew
#

thanks thanks thanks

#

xD

real heath
#

If it does, I don't know. You'd need to look into it further

surreal vector
#

okay thank you

real heath
#

Ofcourse! I always forget that one

surreal vector
#

@real heath i spawned it a meter in front and it still do the bug sorry

real heath
#

You are definitely only spawning one projectile?

plush yew
#

So on this one i connect the Return Value with Set Material Instance- why not straight to the FUNCTION NODE, and what does return value do? again i really googled a long time before asking here

Help, my camera wont rotate

#

Like at all

#

@real heath yes i'm only spawning one at the time

#

I'm spawning it as a separate blueprint instead of being directly attached to the character

#

but it just won't rotate/ move around the player

it follows him and all

what is unreal actually doing while compiling shaders other than using 80% of my cpu and taking two eternities

#

but what does that mean

#

ok

#

but why does it need to do that every time it starts

#

cant it just keep the programs it made the first time?

autumn flame
#

It should unless you make shader changes / modify a rendering project setting and such

Or if you load something with shaders that weren't generated

#

iirc yeah it caches them all, so if you find the settings you need and want to get rid of the old shaders, you gotta delete them

Will free space but you will need to compile the current ones again

Hey gang. I'm live on a film set right now, using xsens for motion tracking and screen recording everything in unreal. We have the xsens stream added to unreal, and as soon as we add it, it recognizes our 3 actors, object 1, 2, 3.

After about 2 second, it collapses the 3 into 1, objects plural.

Anyone know why it's doing this, how to stop it, or how to get around it?

is there a way to move a camera smoothly? i use set actor location (the value will be calculated on the fly)

Hey, how do I make a material or object, that is only visible when it is inside another object like a collision box for example. I only need the part that is inside that object to be visible and the part that isnt has to still be invisible. Whats the best way to do this?

hello best regards, we are developing a pirate video game and WaveWorks 2.0 is the technology we want to use for our oceans, we need a version compatible with Unreal Engine 4.27 or 5.0

If I have a particle beam inside of an actor is there a way I can have the physics relative to it? So if I have a particle beam emitter then the particles will move straight inside the actor and not be bothered by the actor's outside movements

Having an odd issue when building lighting, it'll go through the normal process and get to where it displays 0% and then just stop. Dialog window goes away and that's it. No errors, warnings, or logs that I've found

edit: solved this awhile ago but swarm was being overloaded (couldn't handle the data load). It was really being pushed over the limit by foliage lightmaps. Reduced the resolution, deleting foliage, and moving some foliage to being movable (doesnt use static light aka not baked) solved the issue.

#

Nothing that I've found

# 
[Interface:OpenChannel] Error: System.OverflowException: Array dimensions exceeded supported range.
   at NSwarm.FSwarmInterface.OpenChannel(String ChannelName, EChannelFlags ChannelFlags)

edit: May 17th, this is caused by sending too much data to swarm - not enough allocated size for the buffer. In this case, we have over 100k of foliage and its too much to be sent over. Despite sub-levels creating their own lightmap atlases, this occurs before their generation. 

So solutions are to split how swarm handles it (engine changes), make some/all of foliage be movable so swarm never touches them (incur performance hit due to being affected by dynamic systems - turn off dynamic shadows and use contact shadows to reduce perf hit while maintain some visual fidelity), or reduce/be more conservative with foliage placement across our sub-levels.

#

Hey there, I guess there's a really simple answer but I can't figure it out. Is there a way to make a GUI border image not stretch, but get cut/tiled instead?

#

oh I just figured it out lmao

#

There was a tiling option in the options of the border, if anyone with the same question ever sees this

#

Is there a way to make the image tile like twice the size tho?

#

I have a 64x64 image and I set it as the border image, but it's tiling so many times cause it's small

#

Changing the image size does nothing

#

Oh it's tiling anyway, even if the image is big

sacred yacht
#

Please guys does anyone know how to change the tile size in the border settings?

#

I seriously can't find it anywhere

@drowsy snow ruh roh D: Im having an issue with something refusing to save. Basically I am trying to save a map (one that was downloaded from the marketplace) after I made some minor tweaks like moving objects around, but then it says that "Graph is linked to external private object" and basically its not able to save it at all.

I've actually had this issue before, on and off occasionally, in the past and I still never really learned why this happens nor figured out how to prevent this since I haven't ever been able to find anything when searching about it online. So perhaps you, or someone else, can shed some light on this... would very much be appreciated!

Also I'll paste the actual detailed message in just a moment, if needed.

# 
External Object(s):
Texture2D_2_BaseColor
Texture2D_18_BaseColor
Texture2D_3_BaseColor

Try to find the chain of references to that object (may take some time)?```

oh yeah and when I press "yes" it never works

for me, I basically have to restart the project and try again over and over and once in awhile it actually works

#

but I prefer figuring out how/why certain things happen, as it helps me understand it better cause yeah it is certainly annoying... also it only happens for other content I've downloaded but not my own

spice ruin
#

It's like you're using a texture in your map that exists in a different asset.

#

Are you using the level graph?

lost fractal
#

No, just moving objects around basically before saving. Theres nothing in the Event Graph

#

in fact it actually does it even if I change nothing at all and merely just open the map and then try to save

spice ruin
#

Copy your map file (in explorer)

#

Then open the map, delete everything and try to save it. If that works, delete actors 1 by 1 until it saves.

#

You'll find the issue.

alright i'll try that out

do most of the rocks on quixel bridge only have 3 LOD's?
I'm like 10ft from my rocks and get moderately good detail but 10,000ft away they are rendered with the same LODS.

LOD's look fine, it's just that the lowest resolution LOD is still way to detailed and tanking FPS.

Are most of their rocks like this?

You could easily make an array with a million elements.

I'm not sure it'd be very wise to do so.

That's my back up plan, I didn't want to tempt fate and destroy my foliage by mistake by messing with its base objects. Also didn't want them to change any indexing, rotations or positions, so I could continue to rely on them when having to rerun a short sequence etc.
