[fierce tulip]

I should have removed the one over here though, so I could have pinned the one in materials.
Having said that, you'll need a transformvector after all the rotaboutaxis nodes, else it wont take local rotation into account.
and "manually" as in just rotating the actor itself in the world, and not the any values you are passing onto the mesh trough variables.

[hidden dew]

Oh I see... An issue of which space its happening in right?

Well, the transform it's happening in anyway. I'm pretty sure I get what you're saying... thanks, never thought of that

[fierce tulip]

yes

[plush yew]

Using a niagara particle, I want the particle to appear for few seconds and then stop, how can I make this. Making the particle infinite then making it visibile to invisible cuts the end off. How do I make it appear and then stop and let the particles clear (i hope this makes sense)

[sage coral]

Hi Im using FSR 1.0 everything works expect it looks like my player models when they move for some reason are not AAed anyone know if there is a way to fix this?

Like theres a weird ghosting effect going on around the player like this

[wary gyro]

How could I do that SetRelativeRotation to each of the items in the Part Array? They're all getting the same Rotation value since it's doing it to the whole array

[spice ruin]

for each

Bear in mind that each time Random is used, it will return a different value. If you want them to have the same value, store the result first.

[wary gyro]

How exactly would I do that?

[spice ruin]

Create a local variable and set it to the output of random and then use that random for your yaw input.

Other than that, looks solid.

[wary gyro]

Am I missing something? It still giving every object in the array the same rotation value

[spice ruin]

Oh sorry. That's what I thought you wanted.

Just undo that change!

[wary gyro]

Back to this picture?

[spice ruin]

Yeah.

[wary gyro]

hm, still doesn't seem to be working

[spice ruin]

Are you sure your arrays actually have the values you think they do?

[wary gyro]

Ah shit. I just realized I'm executing this function before adding the parts to the array

Thank you

[spice ruin]

Lol. Oops!

[latent sonnet]

Great to hear man. Ideally you woild be able to transfer scoring, and other elements between level, which will require some third party element like the game inctance, but that depends on what game you are making. finding you own solutions is the best way to learn regardless.

[dreamy wasp]

Using the Nav Invoker, I am able to have the nav mesh thinking only about what is near my character.

but.....

It does not stop the AI enemies from thinking. Is there a way to shut them off, in a branch? How can I tell the character they are no longer inside the nav Area?

I found that once they are out of the nav Area, they constantly do movement calls, and fails (because they can not reach the player). They look like they are turned off, but in fact, they are using more CPU, when out of bounds.

[thin tendon]

In your behaviour tree or code. Just add a distance check to the player. If it exceeds the distance tell your AI to just sit idle and not move.

[dreamy wasp]

yeah, but then, again, that is a constant tick.

[thin tendon]

Just slow the timer down on the function so it ticks less often and its not a performance issue.

[dreamy wasp]

seems correct, on paper, but if all 50 enemies are calling every one second, then there is a steady hitch in the game play every second.

[thin tendon]

50 enemies are going to be running 50 sets of code anyway. 1 extra line isn't that big of an issue

[dreamy wasp]

Its why I have a sphere around each enemy that detects the player, but now I also need to move the nav mesh around, because the player travels so far.
Now, once the nav is away from them, even though they are not touched by the player, they are doing movement calls.

the spere does an overlap check, then brings them to life

[thin tendon]

Just make a variable shouldmove? set to false by default. On overlap set to true on end overlap set false.

[dreamy wasp]

its just a school project, i was doing an infinite runner, but i wanted to add enemy spheres that atack.

yeah.

[thin tendon]

Its not a big issue you just got to tell it when to move and when not to move

[dreamy wasp]

yeah. it was working fine before i started moving the nav mesh around.

I have to recheck my code. see where the move is being called.

Slimwaffle is a cool name btw.

[thin tendon]

Thanks mate. What I do for my AI is I created a population control actor to handle this. Loops over a list of AI. So that way I can check things against a list of entities instead of looping over the world.

[dreamy wasp]

...

That sounds like Star Trek talk

[thin tendon]

The basic idea. Spawn or kill enemies add or remove them to a list. This way if I need to check all my enemies. I already have a list of enemies without having to get references to them all again.

[dreamy wasp]

so is the list in the level blueprint, game mode, or you have a single actor that everyone is casting to?

[thin tendon]

Nah I created a single actor to handle it. For me the main motivation was. If the enemy is x distance from the player. remove it and add new ones. So I can have a dynamically filled world. But only have a small amount of actors spawned at once.

[dreamy wasp]

are you useing event dispatchers to tell them to die?

[thin tendon]

There isn't any need because I just destroy them by accessing them from my list

[dreamy wasp]

thanks. will look into it. need to run.

[true ridge]

Is there a way to hide the actor billboard (the white sphere you see when placing an empty actor on the map) without setting EditorBillboardScale to 0? I want to remove the sphere, but I don't want to hide any child billboards.

[vast totem]

when i simulate physics, the camera stop following my actor, any ideas?

[drowsy snow]

Just press G to enter Game View, it won't be visible in runtime anyway

[true ridge]

Unfortunately that also hides collision boxes and other details.

[dreamy wasp]

looking at action mapings.
Is there a way to do "on release"?
All the mappings i see are 'on press'

[spice ruin]

replace IE_Pressed with IE_Released?

[dreamy wasp]

My guess youa re talking about C++

I dont see that in the Input setting menu

there is only a check box for Ctrl, Alt, Cmd

OMG... I'm blind...... ugg... sorry...

It in the action itself. The node has Pressed and released outputs

[spice ruin]

🙂

[timid cloak]

Hey, sorry to bother, but I've been into Unreal Engine 4 for 1 year, and this has never happened to me. I try to package my game, and it opens https://docs.unrealengine.com/4.27/en-US/SharingAndReleasing. Is there any way to remove this thing, since I can't package with it. Thanks

EDIT: I fixed it and if anyone has this error, just reinstall Visual Studio (no matter which version), since there are missing files that prevent it from packaging the project

[unique knot]

Hey, silly math question, but how can I get a vector velocity from rotation and speed?

[real heath]

Rotation.getforwardvector * speed

[unique knot]

Of course.

[real heath]

Could be .getxvector, I forget

[unique knot]

Thanks Boris, you cleared my brain fart

[real heath]

Lol np

[stable bane]

How do i download UE4 via epic games launcher ? i can't find it there

[stark talon]

@shy nacelle You tried to help me with the flickering issue some days ago.
So far i wasn't able to solve the problem.
But i created a small simple project that shows the problem.
Its just the unit blueprint with the WPO movement, and the update of the position (to correct the bounds).

you are my last hope

Could you please take a look?

I also tried posting on the Unreal forum and still no luck

It would be so good if i could make this work

I tried one frame earlier and after. I also recorded the positions, and tried different last positions.

I will convert it to UE5

Also. The flickering doesnt happen if im zoomed in on the unit. so the position is 100% correct

Its that white flash

yes. the position is 100% correct when updating

its just that there is a white flash flickering in that frame

that only happens when zoomed out

i will show you on video

https://www.youtube.com/watch?v=XBPQsEEiXf8

you can see that zooming in the position is updating 100% correct and there is no flash

the units are moving in the wpo

but when they go above some meters in the wpo, i update their position

the units disappearing?

ignore that

[drowsy snow]

ICYMI, "Horu wizardry" in question:
https://www.youtube.com/watch?v=QVlw_SD8G7k

[stark talon]

that is fine

im okay with everything except the flash/flickering

the units disappearing in the corner of the screen is ok

i can just increase the times they update

okay will try there

[plush yew]

how can i make my niagra particle appear then disapear only for a short moment, right now if I do visibility it will cut off suddenly but i want the particles to keep flowing after it turns off (i hope this makes sense)

[drowsy snow]

Is it a GPU Compute particle?

[plush yew]

I am unsure what that means

[slim gyro]

Hey folks! new here!
just wanted to ask a little something:
Can i open a game project extracted from an Unreal Engine 4.16 game and run it in UE 4.27?

I tried that but... it actually gave me some errors and crashed out

[spice ruin]

Potentially? You could try upgrading it, but it's likely to fail.

You might have more luck upgrading 1 version at a time.

[drowsy snow]

Your chances of getting it work is low, and you could violate EULA for reversing existing game.

[spice ruin]

But that's going to be just as risky.

Oh I missed that part.

[slim gyro]

Upgrading what? look there's a game we made long time ago with my friend, but now we need some stuff in it but we're having issues restoring them

[spice ruin]

"Restoring" ?

[drowsy snow]

Then that's a lesson for you to keep backups.

[spice ruin]

Do you have cooked assets and you want to "uncook" them and go from 4.16 to 4.27?

[slim gyro]

i mean extracting some of the models from the game that r now deleted from our PCs ya know :')

[spice ruin]

Yeah, that's not something that's supported here... or even legal.

[slim gyro]

Well i think so, i'm talking about the .pak files

[spice ruin]

Reverse engineering games is against the rules here. Even if you own them.

[slim gyro]

Ik ik but i saw some videos showing it's possible, so maybe we're gonna clean this mess :')

[neon bough]

if you watched a video about it, you should know what to do

[slim gyro]

Ooh! umm.. okay then

[neon bough]

also, considering the little chance that you really are author of the pak... make backups

[slim gyro]

yeah but they were actually doing it with their game made in the same version of the UE

[neon bough]

then do it with the same version...

[slim gyro]

ok ok got it, let's just end this conversation up i guess

[sudden vault]

How do i disable frustum culling for a specific actor?

how can i save/load a save game into the game folder where the executable is and not the user save files?

or put the save file in the content folder itself?

[quaint torrent]

does anyone know how to disable this popup? i have 17k more normal maps to import and this stupid fucking popup is slowing my computer to a crawl.

[neon grove]

why would you have 17000 normal maps??

[quaint torrent]

because i have a lot of textures that need normal maps lmao

[neon grove]

what sort of game needs 17000 textures?
dont you reuse some of them?

[quaint torrent]

most arent even getting cooked its pretty much just huge packs being used to reference one or two things for no real reason (im not the lead here)

trust me i realize how fuckin dumb it is lol

[drowsy snow]

Alternatively you could import them bit by bit

[quaint torrent]

yeah just dug through all the settings and realized thats probably the only way to go, thanks

[silk flare]

imagine if Unreal had Blender-style modifiers

array, simple deform, mirror, ...

I know there's a plugin that's supposed to do this but I'm not sure if it's actually out on the market

[spice ruin]

A plugin, you say?!

[silk flare]

lemme find it

https://forums.unrealengine.com/t/geometry-modifiers-bend-twist-stretch-squash-and-more/63095

hello I just edited this on my fire function but why after doing this fire is being 1 shot? it was auto shoot when it was only input fire. please someone help me

so is the button pressed and released function is here

[real rain]

Hi, I was wondering if it's possible to disable step down but not step up?

I have a fast character, I want them to enter falling state if they run over a hill for instance, rather than latching to the ground

@plush yew are you looking for a way to do auto fire like a machine gun?

[plush yew]

No I did it was autofiring but after doing that it sing shot

[real rain]

ah ok, im not sure which one you want, autofire or single shot?

[plush yew]

Autofire

[plush yew]

But doing this its automatically 1 shooting

[real rain]

ok, you can achieve that with a looping timer. Use SetTimerByEvent in blueprint, set it to loop, and make a custom event (right click -> create custom event), hook that up to the timer. Then promote the timer to a variable. On FireButtonReleased, clear the timer

[plush yew]

Ok I will try when I am on pc BTW thanks

[real rain]

no problem!

Does anybody can help me for this hell situation?

Or somebody have tutorial for integrate oculus SDK?

[thin urchin]

Does anyone know if there is a way to delete references in UE4? I am struggling with some assets in my scene when I package the project. Because I migrated them from another project there references from the other project still remain making it so I cannot package the project. Any ideas?

[plush yew]

[thin tendon]

you could try right clicking and checking out the reference viewer to figure out which assets are referencing the items in question. You can also try clicking on your content folders and fixing up any redirectors

[thin urchin]

I've given this a go but I solved it in the end by migrating the level to a new project so it only brought the necessary files through and it seems to have worked

[marble iris]

How'd you fix it though?

[dreamy wasp]

QUESTION:
In any blueprint, on the left there are lot of variables under the blueprint tab.
I want to start organizing them, but I can't figure out how to add a folder or group.
rtClick just allows me to add more variables, functions, macros and graphs.

[plush yew]

I made a cannon but the cannonball is falling through the floor, how can I add collision to it

[proud abyss]

Just removed the displacement map for the moment. Need to go back and set it up properly today

[thin tendon]

If you made it in blender just add another object with the name UCX_<your mesh name> _001.

Or you can just open the static mesh and add a sphere or box collision from the settings at the top of the screen

[plush yew]

I just changed the collision present to custom and blocked all except pawn + world dynamics

seems to be fine

[hidden dew]

Is it ok performance-wise to send a 1024 x1024 texture parameter to a Material Instance Dynamic every update?

Is that a normal thing?

[drowsy snow]

Depends on how you load them.

[plush yew]

can i import starter content into my existing game which started with none?

[drowsy snow]

Streaming from disk right away can cause hitches

[drowsy snow]

Yes.

[hidden dew]

What about a runtime texture

[plush yew]

where

[hidden dew]

Wait, that might be the wrong terminology

.. a Runtime Canvas Render Target

[drowsy snow]

Add Content button in Content browser

[drowsy snow]

It's fine, except drawing to RT can be quite heavy on performance. Lots of high level fluid sim suffers from heavy perf.

[regal fog]

Hello!

I need some help with something

How do I make a 3d menu background that can change like ex: beat the game

[plush yew]

thanks

[drowsy snow]

Just having the level as the background, instead of full screen image widget taking over

No black magic there

[regal fog]

I know that, but the background actually change as your progress through the game, that what i meant

[hidden dew]

Right. I'm guessing that means if I'm only calling SetTextureParameterValue once per update, I just have to watch out for how much I'm calling DrawTexture per update

I'll have to find out how many is too many

[drowsy snow]

You can keep track of it with the save data to determine the status of the main menu map. That's how Spec Ops The Line did it.

In the case of FF15, I think it's a global save file checking whether you've completed the game once instead of the last save slot.

Hard to do any of this for 10 minutes when you're hot

[stark talon]

cold shower thats what i do

[hidden dew]

Sorry, that wasn't helpful for your question hehe
And yeah, basically.

[hallow ivy]

i mean this question in the most respectful way.
why do people still use ue4?

[drowsy snow]

Having project already far in development.

[hallow ivy]

cant upgrade?

[drowsy snow]

Upgrading to even newer version of UE4 can cause trouble with existing code base for the game.

[hallow ivy]

i expected ue5 to be backwards compatible

[drowsy snow]

See, more sophisticated projects have more C++ code, and often times modifying the engine source code for the project. Upgrading to new version means adjusting the game code to the newer API, and bringing over engine modification to newer version, which doesn't always work first try

[hallow ivy]

but it cant be THAT much of a pain in the ass, can it? because blueprints are basically the same, meaning most functions even in c++ are the same? im no expert and i have no idea about anything im just asking

[drowsy snow]

Newcomer projects or BP only is not that consequential moving to newer versions.
Also BP is higher level scripting and on top of C++. One can have lots of valid reasons to program the game in Unreal C++ and went their way to modify the engine source code to modify their needs.

And no, it can be PITA.

My engine modification still doesn't fully work in UE5, even then it doesn't work at all in the first try

[hallow ivy]

ah got it

thanks

i have no idea what this is but thanks for the info anyways

i know the quest

dont know why it needs a fork tho

really?

ue5 supports vr though

its listed as an option

dont know if it works

[drowsy snow]

People still cling to Unity for XR needs

[hallow ivy]

are they really basing their engine on the needs of fortnite?

doesnt seem like a smart business move

[spice ruin]

Are they really basing their engine needs on their highest grossing product? Yes? OMG WHAT A SHOCKER.

[hallow ivy]

their engine is used by multimillion game development studios and they make money from those games so they need diversity to attract devs

[spice ruin]

No they don't.

They already attract all the ones they need to.

[hallow ivy]

lol

[spice ruin]

They don't need to attract business that comes from companies below 1000 employees.

[hallow ivy]

true

bigger fish to fry

probably subnautica?

i think subnautica was made by unity

raft

oh right

the unity ads platform sucks

most of the time the ads dont even load right

i think they cancelled it

[drowsy snow]

And proceeds to disband the team

[hallow ivy]

yep

stupid imo

and makes the people think of them as a bad company

mainly because they are the only good game engine

and also because c# can kiss my ass

[drowsy snow]

Also talent

[hallow ivy]

i hate it

[drowsy snow]

More people studying UE since UE4 went publicly available

[hallow ivy]

no logic behind it

i am

i actually have a beginner certificate

[hallow ivy]

wdym publicly available?

[drowsy snow]

Let me dismiss that as a recruiter...

[hallow ivy]

probably wont do anything i know

not even from a well known course provider

but i still didnt go to college

hopefully a degree would be a enough to get employed

[drowsy snow]

As in fully fledged Unreal Engine being available for public to use (initially with $19/month subscription)

[hallow ivy]

dude that was more than a year ago

or dudette

no offensiveness meant

[drowsy snow]

8 years ago to be exact.

[hallow ivy]

oof

why did i only recently hear about it?

[drowsy snow]

Full suite of UE3 editor wasn't available to the public.

Sure, UDK is a thing, but it's a little bit watered down

Before UDK you'd have to piggyback a moddable UE3 game, like Unreal Tournament 3

UE4 is available to public for realsies, initially (2014) you have to pay $19 per month, until Epic made it free to use a year later

[hallow ivy]

but it still has a cut right?

[drowsy snow]

I still remember how hyped I was first time seeing UE4 become free to use.

[hallow ivy]

once you reach 1m profits they start taking 30%

[hallow ivy]

old

[autumn flame]

Actually 5%

[split tundra]

I might be misremembering but wasn't it 5% off monthly?

[drowsy snow]

Yes, but before that the limit was $3000 per quarter (3 months)

[hallow ivy]

really?

only?

wow

[autumn flame]

Yes

[drowsy snow]

After $1M, 5% cut after $10K per quarter

[hallow ivy]

wait so every 10k i make per quarter they take 5% of?

[autumn flame]

Of course you gotta consider if you publish on launchers, they take their fee from the start

Steam is 30%

[drowsy snow]

After you reached $10K in a quarter. First $10K doesn't count

[hallow ivy]

oh

that makes better business plan for unreal but it sucks for us devs

not like ill reach 10k per quarter anyway

[drowsy snow]

If anything it's better for devs

You pay nothing if you didn't reach that threshold.

[hallow ivy]

so if i launch my unreal engine game on steam rather than epic, epic takes a bigger cut?

[autumn flame]

No, you pay 30% to Steam

[hallow ivy]

same thing with the 1 million?

[split tundra]

No, that's Steam's cut @hallow ivy

[hallow ivy]

yeah that i know

[split tundra]

You pay both Epic's and Steam's cut

[hallow ivy]

but i think epic at least discounts the cut if you release on their launcher?

[autumn flame]

Epic is still 5%

[drowsy snow]

Yes, that's $1M total since you first sell it

[hallow ivy]

ohhhh

[autumn flame]

No, just they take less of a cut on the Epic Games Luancher

[hallow ivy]

got it

[drowsy snow]

The 5% cut for UE doesn't count if you publish to EGS

[autumn flame]

12% iirc

[hallow ivy]

thanks

[hallow ivy]

yep see thats what i meant

[drowsy snow]

If you're going to sell your game, be prepared for spreadsheet action to count the sales.

[hallow ivy]

yeah at this point if i sell for 10 dollars on steam ill probably get 6ish

[split tundra]

My Paper2D characters are using a custom billboard material and I was wondering something: if the light comes from behind the character (which would actually be their front), since they're billboarded they'll always be facing the camera, showing their front, and thus their back'll be affected by light, but since they're billboarded, I won't even notice.
How would I make it so that light on a billboarded sprite affects the front and not the back?

[hallow ivy]

anyways i gtg

[split tundra]

If that makes sense

[hallow ivy]

thanks guys

[drowsy snow]

I'm afraid not, can you make a quick sketch of it?

[split tundra]

Sure, give me a min or two

Hopefully this is clear enough ahah

And I'd need the light to "somehow pass through" and light the front as well

I know I can just change the light direction, but I was wondering how I'd deal with something like this

[drowsy snow]

So backlighting?

[split tundra]

I guess that is it

How would I achieve that? Since my sprite is always facing the front and it isn't affected by light if the sun is coming from behind it

[drowsy snow]

I'm thinking of doing the old trick of duplicating the sprite, making it unlit, and slightly offset it according to the light direction.

Though it's only going to work well on per scene basis

[split tundra]

Yeah, this is the problem, if there was a way to just let light pass through, so to say, that'd kinda solve the problem for whatever direction the light is emitting frm

[visual slate]

can someone please help why the translucency greyed out?

[arctic carbon]

is there a way to loop a video in unreal engine ?

[spiral schooner]

Hi. Have any Tips for a dual computer setup? I daily drive on one Windows 10 machine but would like to include a 2nd to test multiplayer projects. Just wondered what other peoples experiences were given UE offers some options for doing remote work. I guess I could go the physical route and invest in a KVM switch, yada, but if Unreal 5 has something that works more ideally I'm all ears.

[plush yew]

how can I make niagara particles fade away instead of disapear (setting visbility makes it suddenly go "poof"!

[real heath]

Nothing specific to unreal for that afaik. I personally use parsec for remote controlling other PCs. It's very responsive and great for 3d and video work

[spiral schooner]

yeah I remember parsec, moonlight and vnc...

[real heath]

i'd use parsec and moonlight for unreal work. VNC is great for remote administration, but in my experience, not so good for interactive stuff

[whole turtle]

Hey everyone! Has anyone released a free game on ItchIO using ue4 before? I've just finished a small prototype that I wanted to release on my itchIO page for free. Does anyone know if I still have to fulfill any of these requirements for that (https://www.unrealengine.com/en-US/release) ? Do I have to add Unreal Engine logo, state in the credits that it was made using the engine and fill in the form to notify epic games about my tinny free prototype that I'm publishing in my ItchIO page as a portfolio piece?

[young crag]

Any solution ??? ..

[oak patio]

i would imagine so. not sure about the form, but adhering to the ue license agreement through crediting the engine, and adding a eula will be necessary

at the end of the day its a product

Howdy, I'm used to creating buildings with bsp then converting to static mesh in ue. Is there a better method? I like using bsp since I can correctly size and material everything in-engine, but I've had issues in the past where if the DDC cache folder is cleared, the material slots on the converted mesh are completely jacked up and no longer allows me to change the materials within such slots. Any tips or advice for me to use a more efficient method? I'd like to get in a groove with something new before I start another project.

[oak patio]

making actual meshes in a dcc. you really shouldnt be using bsps past your blockout

whatever you are doing in bsp is likely better and more easily done in a dcc

[mellow coyote]

Damn, that was a quick response. What dcc do you usually use for ue?

What do you prefer?

[oak patio]

blender. prett ymuch has everything that maya lite has, is free, and has a less steep learning curve imo

also feels less dated

have used maya, 3ds max, and blender, must say blender is by far my fav

[mellow coyote]

Nice

I deal with a lot a building work. What approach should I take when creating something in blender and hoping it stays true in UE?

Or vice-versa

[oak patio]

it will stay true as long as you dont rely on blender materials and use proper unit scaling

apart from that its just setting up units correctly, then making sure you measure things properly

personally for my modular assets i make sure everything fits nicely in a 2x2 meter grid

[mellow coyote]

So I should make sure all the units are sized the way I want before starting ANYTHING

[oak patio]

yes

if your unit scale is off at the start it is a pain in the ass to change mid way through making something

[mellow coyote]

I would be using all ue materials

Yeah, that would suck

[oak patio]

set it up, save it as your preference, then you never have to worry bout it again

[mellow coyote]

Sweet

I'll be starting my forth project, but this time in ue5 so I wanted to do something right this time around lol

Because it didnt sit right with me using bsp conversions in past projects

Since I know bsp are performance hogs

And didn't want to come across that odd cache folder crap again possibly destroying an entire level.

You've been a great help man. Thank you

[oak patio]

Yeah. Bsps are alright for greyboxing but I wouldn't push it past that. Hell even for greyboxing I'd rather use blender, block out tools plugin, or even ue5 modelling mode

[plush yew]

is there any way to convert ue5 project to ue4?

[real heath]

No

You can go up, not down

Same goes for .x releases. 4.26->4.27, 5.0->5.1, not the other way

[plush yew]

why man why

[real heath]

Cos that's how it works

[oak patio]

Stuff don't work in reverse. If the implementation of a node changed, or youre trying to use nanite features, and then you downgrade to ue4 what do you expect it to do aside from break?

[plush yew]

Nah I didn't edited in ue5 🙂

[oak patio]

I'm not on about stuff you did though

I'm on about the engine

[plush yew]

ohh ok

[oak patio]

If the engine changed the way it does things and you try to go back, things can only break, so why bother giving an option to go back

[plush yew]

wait

@oak patio I have an idea

if I migrate it from ue5 to ue4 it will work right?

[oak patio]

No.

Only assets like meshes can be migrated back really, by re-exporting them. You cannot migrate a BP made in UE5 back to ue4

[dense knot]

This is the house so far (lots of adjusting and addons to do) it's the tutorial level. What do you think? (it's a horror game and the house is specifically laid out to have a lot of turns so the player wonders what is around each corner even though SPOILER there are no enemies in the tutorial, Just a simple jumps care cutscene at the end to explain the transition from this level to the next map. (I am also keeping the scripted jump scares to a minimum. https://drive.google.com/file/d/1DHsGXK44COS-JneWZJzr69y1Y3QGls9B/view?usp=share_link

[whole turtle]

yeah, makes sense. I might as well just fill in the form, thank you!

[tardy flume]

I'm attempting to export a skeletal mesh from Blender into Unreal Engine 4. When exporting on Blender's default operator settings, the model in UE4 comes out angled -90 degrees on the X axes while in Blender it looks normal. When I edit the export settings with -Z forward, Y up in transform and -X axis in Primary Bone and -Y axis in Secondary bone and export it, it doesn't look good in UE4. Bones are twisted. I import it in Blender, the model is again 90 degrees on X axes, but then I export it with the SAME settings and suddenly it looks good in UE4 and functions proper like any skeletal mesh. The only issue is, physics assets don't recognize it for some reason and go all weird. It's a big mess, because I don't know how to fix it. Was hoping somebody here had an idea.

[spring abyss]

heyyyyyyyyyyyy]

Does Anyone know how to fix this?

[wild crag]

@wraith stratus What up?

add me if you're still interested, it broke

[oak patio]

oooh not good. that shouldnt be happening. try verifying your engine install

[spring abyss]

oh i did it

and most of the warnings are vanished

there are still some left

these are the errors

[dark venture]

I need help when I pick up my weapon and go to another level the weapon seems still attached to the character in the outliner but it disappears in the game. I have a game instance but I don't know how to save the weapon in it.

another question how can I assign my weapon as an enumaration?

[plush yew]

using the DM plugin, the parts act really un-naturally. Any fix to this?

Hey

Now

The problem is even reduced

But

Now the prob is that

Hello everyone, I am looking for some information.
I am the wiki admin of an indie game developed in UE4.
The game includes a recipe book with images of the items. For the wiki we would like to export these images.

We are currently taking a screenshot of the recipe book, cutting out the item image and removing the background.
This is a lot of work and takes a lot of time for about 275 items.

Is there a way to export these images from the game using UE?

[drowsy snow]

You could somewhat automate the process in the editor by dumping render target into an image file (though I'm not sure if BP had that exposed)

[midnight light]

Can I find instructions somewhere on how to do that?
Just so you know, I have zero experience with UE 😟

[spring abyss]

hey hey

someone solve my problem

[drowsy snow]

hey hey
would be nice for you to rephrase your question

[spring abyss]

I tried packaging my game

It failed

and some errors and warnings were there and i am trying but dont know how to fix it

Hiya everyone. I'm after some help with selecting static meshes in the outliner. Basically I have a datasmith object which has a bunch of sub hierarchy that I am trying to select just the static meshes from without selecting all of the actors, is there a way of achieving this? Picture for context

I would do this manually but there are 20,000 static meshes

The reason I would like to select all of the static meshes is so I can set there max draw distance

[shell compass]

Does anyone here use the Unreal Engine docker container? Is there any benefit to it or is it a niche/novelty thing?

[marble iris]

The node is called Set Visibility, it's also in the details

[coarse jetty]

im refering to details panel, not widget.
toggle visibility from this

[marble iris]

It should be the same thing as it's called in the details no?

[thin urchin]

Okay I solved my own problem. Might be helpful to someone else though. It's a bit of a backwards way, you select the objects that you want to select in the viewport in the content browser instead and right click and choose the following:

Hi everybody! I'm someone that wants to learn how to do good cloth physics in UE (posted in #legacy-physics but I don't think anyone is interested to help me out there) so I was wondering if I could catch some interest by paying someone who thinks that they are suitable for this case?

Seems like a terrible kit anyway. £300 for ultimate shooter that doesn't even include one of the basic controls, that being crouching

Makes me wonder what else is lacking

Also reviews so the documentation is terrible

[oak patio]

Set the eye's rotation to be the find look at rotation for the player

Unless you mean with a procedural anim

[magic helm]

Ahh I see, I'll look into these, thanks guys! :)

[marble iris]

Fixed?

[plush yew]

Just say will it work on android I have this kit

[coarse jetty]

no, i guess i have to go for custom components in c++ or something related. Nvm they will be always public, no problem, just curious if it was easy or i was missing somthing. Thanks for the interess, if you need anything here i am.

[oak patio]

It doesn't explicitly say it does so not sure. No way for me to tell, you're just gonna have to package a test project.

Still wouldn't recommend using it tho

Hi Had a question. Havent really been able to figure out how this works fully but to give an example.

Let's say after my project is finished and is published to steam if it gets uploaded to steam and I wanted to add more content, how can I update the game do I just need to rebuild the most recent build of the game and resubmit the project? I havent found a lot of documentation on how updating your finished project works after launch not that I'm at that point yet just thought it would be useful info for the future.

[oak patio]

you can just upload a whole new build iirc, but i also seem to remember in packaging settings it gives you the option to package only new content into a patch

[sage coral]

Thank you for the info it definitely helps 🙂

Hi guys. Help me please. I need to update my engine version to Unreal 4.27.4 but for some reason I can't see it inside the launcher. I only have Unreal 4.27.2. Am I doing something wrong?

I would think you're right. But I'm trying to use a plugin that wants me to use 4.27.4. It's written in their documentation. At first I thought it was an error, but I was able to find a video that was using that version (unless it's also an error).

This is the plugin. It's called Runtime Datatable.

I think you're right. But then I'm still lost, because they say that's what I need to use. I'll continue checking it out in that case. Thank you very much 👍

[drowsy snow]

Just change or remove the engine version in the .uplugin file.

.uplugin is just a renamed JSON file, so you can open it in Notepad

Interesting. I'll try to do that right now.

[rose cloak]

Anyone here know if a component can call an event or function at its parent ?

[fallow kindle]

I Don't know, but, you can check for tutorials on youtube, I'm sure there's some that explain that @rose cloak

[hidden dew]

@rose cloak There's a GetOwner() (or something like that) for components

Waiting for Visual Studio to do the world's slowest text search

Like this:
Planet = CastChecked<AMorphingPlanetOfCells>(GetOwner());

I called that from the component's class

[rose cloak]

Thats where I am. Using Self->Get Owner. But when working in the component it actually dont know that owner at that point. So I need to 'hardcode' the names of the events of something similar.

[hidden dew]

So then Planet is a pointer to the owner, then you can do whatever

hmm

[rose cloak]

I have seen Event on Timer or Timer on Events, where you specify by name the event you want to fire. I am looking for something similar.

[hidden dew]

I can't help too much beyond that sorry

I've used events.. once.

But do you mean, the component you're calling from doesn't always know what class its owner is?

[rose cloak]

I am looking something similar for events.

[rose cloak]

Yes. thats the point with Components. you can add the Component to any kind Actor and give the Actor some functionality. But as component you dont know who you are being added to, so the workflow is abit tricky.

[hidden dew]

yeah, fair enough

[rose cloak]

LOL!. I had the function the whole time. Use Set Timer by Function Name. Does exactly this. I just make the function call an event.. Great!

[dreamy wasp]

Question about Grass:
I have watched several 'tutorials' but they all assume a basic knowledge of grass. Strange, huh?

1. Does anyone know of a good basic tutorial on grass for UE4?
2. Can grass be added to something like an office planter, and spawned into the scene, or does it have to be part of some special landscape obj (still not sure where this comes from, but I find it in the grass examples). ???

What I am looking to do is spawn Large cubes (bed sized) with grass only on the top. these are floating platforms that move, for a section of my platformer game.
So this grass would be inside of a spawning blueprint actor.

[neat marsh]

is it necessary to add OVR_plugin for use OSS_Oculus?

[hidden dew]

2. You can paint grass onto anything, not just a landscape, using the Foliage tool:

I don't use it though, so I honestly don't know whether the grass will move with a moving platform,

[dreamy wasp]

So where is the option for the foliage tool when you are inside the blueprint?
I don't see it as an option, nor a component.

I create a static mesh........ then?

[hidden dew]

Hmm possibly the tool can only be used for stuff that's already in the level, not spawned in runtime.

I really know almost nothing about it, except that it's there

[dreamy wasp]

hmmmm.... yeah.. this is what im afraid of. damn.

me too. lol

I just thought it would be nice to add grass to a moving platform. I never used any of the landscpae tools before.

[hidden dew]

I just gave it a quick try

Unfortunately it looks like the grass won't automatically follow what the tool was used to put it on

I was hoping it might have a little smarts, but it's not too surprising

[dreamy wasp]

I can bring in grass, but clump by clump. that's a ton of draw calls. I was told the foliage tool puts them all together and optimizeses it a bunch... soo...

[hidden dew]

Yeah

It's the moving that will be tricky though

I've been trying to do my own grass stuff lately, similar to what you're doing

[dreamy wasp]

nice

[hidden dew]

The Foliage tool uses "Hierarchical Instanced Static Meshes" (sorry if you already know this)

[dreamy wasp]

no idea

[hidden dew]

I've been spending a lot of time trying to get my own grass to move in a way that doesn't annihilate performance

I use a HISM component too, like the foliage tool, but it still does not like moving a lot of things at once

It can, but it depends on how many

Like, it specifically has the tools for moving & rotating. It just doesn't like very large numbers

[dreamy wasp]

so a treadmil of grass would be out of the question.

[hidden dew]

But yeah, if Unreal doesn't have a nice easy way to even just move grass with a floating platform, that's the kind of stuff you'll have to be thinking about

Another user said he could shift 10,000 meshes with it without a concerning performance loss

(Not sure what his machine's specs were though)

[dreamy wasp]

well. I'm super restricted on mobile

[hidden dew]

So a treadmill could be possible, sure

Ohhhh

Still maybe. I just don't know

Maybe the same thing still works, but you'd only get away with like 1000 pieces or something

shrug

[dreamy wasp]

I got a bunch of 3 meter cubes that randomly spawn, and at diffeernt heights.
The heights change based on what other cubes you stand on, so the ones with grass need to have th grass move with the cubes, or it will look really odd.

[hidden dew]

Yeah

[dreamy wasp]

currently its just a texture.

I wanted it to look a ... little... more...... 1990s+

not pre 80s

[hidden dew]

Moving lots of grass gets a little complicated, so I wish I could suggest another method (other than ISMs, HISMs), but I think that might be what you have to look into.
I'm not sure if it's mobile friendly, but I guess it probably is?

The approach you'd have to learn about is something like:

• Add an Instanced Static Mesh -- or Hierarchical Instanced Static Mesh -- component to your project somewhere (I'm not sure where is good for you)
• Figure out a way/maths to place every piece of grass randomly
• Do the calculations you need to do whenever the grass has to move, and use the function (or node) UpdateInstanceTransform to tell each piece of grass where to move

From what you described, just using an Instanced Static Mesh (ISM) component would be better than a Hierarchical Instanced Static Mesh (HISM) component.

The HISM has support for better culling... like showing different LODs, or culling any grass that is too far from the camera.
But it also comes with its own overhead, and it has what might be a bug in a packaged game that ISMs don't appear to have.

Since it appears you aren't needing vast fields of visible grass, it sounds like ISM would be dandy

[dreamy wasp]

wow. people kept telling me grass and forests were easy, now.
lol

[hidden dew]

yeah

The thing with Unreal is like: Do it Unreal's way - easy

Do anything else - ugh.

[dreamy wasp]

yep

Leave it to designers to want to do somethin unique

[hidden dew]

So the above stuff is a chunk to learn about, before even knowing what the performance impact will be, assuming it works on mobile

It's the number of calls to UpdateInstanceTransform that will be your bottleneck, more than the amount of grass itself.
If you have a tonne of grass and only need to update a little bit at a time, maybe a HISM will be better. Not sure, just that's the rough difference between the two. HISM can do things per-instance better. ISM is more like "Updating 1 thing updates everything".

Oh, I forgot, a different approach

Yeah yeah yeah

You can instead move all your grass via its material. So the grass isn't "physically" moving as far as your CPU/collision knows, but visibly it will move.

The stuff to learn about for this approach is something like:

• Create a material that every piece of grass uses
• Have a Material Parameter Collection, with a Scalar parameter value. This scalar would contain the ever-changing platform height, or height difference, or something like that, and your game logic updates that scalar every update.
• Finally your material reads that scalar and applies it, using the World Position Offset pin, to make every piece of grass appear to move.

Sorry, forgot about that approach.
The big deal here is that from what you described, all your grass can follow simple mathematical motions. Ie., you aren't needing to move each piece completely separately.
That is a huge deal, and actually is why that 2nd approach (using a material) would be much better than the earlier one (ISMs, HISMs)

If you have 100,000 pieces of grass moving the same way, a material won't sweat it, but a HISM will roll over and die.

Sorry I almost sent you down the worse path for the situation you described

As long as you don't need to do anything really meaningful with each piece of grass (ie., it's mostly just for show), then the material approach will be way better.

[dreamy wasp]

I will give all this a look after dinner. thank man.

[coarse jetty]

hi can somebody give me advice of how can achieve this?

i want to control via slidet the "blend" from one position to another of animation, imagine the animation of raising hand, slider 0 hand down slider 1 hand up

where should i llok for? im downloading ue4 blueprint examples bc i guess there is something related

[hidden dew]

@dreamy wasp
I just remembered and should be clearer.
The stuff I wrote above makes it sound like you have a choice between 2 technologies: Using an ISM/HISM, and using a material.
Really, you have to use an ISM/HISM regardless. Consider that to be non-optional.
(You mentioned draw calls. Reducing draw calls is the purpose ISMs/HISMs exist to serve. Anyone doing a lot of grass without Unreal's tools will be using an ISM/HISM, which is what Unreal's tools use too).
So for all I said, yes, get into using an ISM/HISM regardless of anything else.

The option you have is about how you choose to move the grass.

1. You can use UpdateInstanceTransform, which is a ISM/HISM function.
2. Or you can use a material, which fakes the movement but offloads the work to your video card.

Option 1 is much simpler.

• You'll already have an ISM, so you'll already have UpdateInstanceTransform available and ready to use.
• Performance gets worse with the number of grass instances you wish to move at once.
• But it should be ok under a particular amount (that I can't guess for mobile but think of around 10K for a decent PC).

Option 2 is potentially much faster, mostly because your grass can move collectively in response to maybe 1 or 2 values.

• You would take advantage of this by writing some Material logic that knows how the grass should move, just from those 1 or 2 values.
• Performance doesn't get worse with the number of grass instances you wish to move at once.
• It does come with some extra drawbacks, like shadows, collision, and culling not working as expected. These can all be worked around.

_
Final note:
You might discover "per-instance custom data". It's an ISM/HISM feature that is already setup in Unreal and ready to go. You can even change it on the fly in the Editor.
It lets you send data to a material, per instance. So you might think that's a good way to feed data to the material for Option 2.
It's not. Per-instance custom data is just as useless for updating many instances as UpdateInstanceTransform is, I believe because you can't batch custom data in a way that's serious.
The important thing in all this is that you don't want per-instance anything. The material approach for moving grass is powerful because you can send 1 or 2 values to rule them all. Like "move all grass to Z = 50.0. Done."

Any rough idea?

[dreamy wasp]

That is a really tough question, unless you are talking about buying your own game, or giving away free copies.
How many downloads is a combination of people knowing your product, it having good reviews (from actual people), and being a cost that seems worth it.

[floral solstice]

Hey I’m sending some files through to someone but what one is correct

[pulsar helm]

.umap is the level, BuiltData is lightbake, reflection capture data etc.

[floral solstice]

So overview unappealing or demo map

Auto correct

I meant

[pulsar helm]

do they have the rest of the project?

These files are useless on their own

[floral solstice]

Overview umap or demo umap

R they

[pulsar helm]

Yeah they just store references to all the models etc, not the models and so on themselves

You probably need to put the whole project in a zip file and send that

[floral solstice]

I hold the whole project file

[pulsar helm]

yeah give them the whole folder

[oak patio]

Depends how much you are willing to spend on cost per click

Say you bid £1 per click, and wanted a month of advertising getting 10k downloads. Assuming 20% of people who see the add, download the app, which is a very generous estimate, then that would set you back £50,000.

Advertising is expensive. Obviously there are a ton of factors that increase and decrease this cost, so you should really do your own research to determine the factors you need.

Those numbers were the default on a cost calculator, so probably aren't representative, as the cost per click and conversion rate depends massively on who you are targetting

[fluid lance]

How would I go about testing my game on fake "different hardware" that actually works?
Context: The game runs fine at about 80-100fps on my setup (which is an r9 5900x RTX2060, 32g ram). However, when it's ran on other hardware I have no access to (testers from abroad) it runs at ~40-50 fps. I know the problem might be shader complexity, but otherwise I'm "blind". Is there any way to emulate/limit hardware capabilities to see which tweaks help?
Any ideas are welcome 🙂

[thin tendon]

you could run virtual machines

[fluid lance]

@thin tendonYea, thanks. I researched into it and it seems that if allocated resources are lower than demand from application, the VM "breaks" and will tap into existing resources. Better ones at least estimate a threshold. In worse cases, you don't even know it & only find out it has nothing to do with the real thing and it doesn't work one bit for this purpose :/

What does Assertion Failed mean

for an UE4 crash, I get it when i enable hair or moustache on a imported MH

Well, that clears it up 😄

yeah it's wierd i only get it with the MH hair, i disabled it liek a year ago, but now i kinda need it

and poof crash 😦

I will try to recreate the problem

Actually i dont have time for that, I just needed to know what Assertion Failed ment in UE4 context 😄

[wary gyro]

I'm using the Advanced Locomotion System plugin and am trying to make the player grab an Actor instead of just a static or skeletal mesh. But this isnt working? It works fine if you use a skeletal mesh.

[trim belfry]

"something bad happened" is slightly more precise

[trim belfry]

It's not specific to unreal or even C++. Like Laura said you need to post the assertion that failed if you want any meaningful help

Hi guys,
Firstly I want to say I know nothing about this chatgpt ai that I have been hearing people talk about recently, I heard it is an ai which can be used to code ?

What I was wondering is if anyone knows whether it can help with blueprints in unreal engine somehow? I have always struggled with the programming side and I am wondering if I should be looking into it ?

[plush yew]

just leave it it will help you in very basic things

[regal mulch]

From what I've seen it's something you should 100% avoid

The answers are totally mixed up and wrong

Learn it via traditional ways of text and video tutorials, or a tutor

Don't use AIs that collect random sh*t from the net

[frank oar]

Thank you for the advice!
Sounds like good sense

Does Epics' Direct Payment available for UE developers to use?

[drowsy snow]

Wasn't Epic's payment system backing off of Xsolla?

[drowsy snow]

As what others have said, do yourself a favor and learn UE the right way. It takes time, sure, but worth more than blindly believing whatever ChatGPT spew out even with decisions that are... sus.

Rome wasn't built in a day, and even passing off AI gen artwork as your work, as is, is frowned upon even by sane AI gen enthusiasts.

Merry Christmas everybody

[rotund sorrel]

How would you apply blur (only) around a specific character?

[drowsy snow]

Depends on what effect are you actually trying to achieve

[rotund sorrel]

https://youtu.be/4ccBjlAFt0s something like the thumbnail of this video (maybe a bit less) but only around the character would be good.

[drowsy snow]

You can use the same thing but mask out the character with custom depth

[rotund sorrel]

Will look into that thanks!

[latent sonnet]

could you not add that same material to a component that is part of the character but surrounds it?

[rotund sorrel]

You mean assign the postprocess material to the mesh?

[shut fog]

Hello, how can I reduce the tickrate of my PIE dedicated server?

[rotund sorrel]

it works but it would be better if the outline of the blur was a little bigger then that of the character itself, like it is in the thumbnail. Any suggestions on how to have a bigger mask (but still with the shape of the character) without increasing character size?

[latent sonnet]

no, an additional mesh that is bigger than the character and is attached to it

like a surrounding capsule of sorts

[rotund sorrel]

But should it be sorta like translucent then?the material in the video is a postprocess one and is applied to the scene texture, not sure on how to convert it to a surface material

[latent sonnet]

is it a normal matrial? can you just apply it to a mesh?

if so then wouldn't hurt trying

[rotund sorrel]

I don't think it is because it uses scene texture uvs as input and is set as postprocess

[latent sonnet]

i say try

[drowsy snow]

Good luck actually trying

[drowsy snow]

Not entirely sure how outline post FX were done, but maybe using that technique to bold the mask more

[latent sonnet]

can you not just scale the mask somehow?

[wooden heath]

is there solution without plugins for facebook Auth with unreal 4 ?

[tardy flume]

I'm running into an issue, I understand that it's a rare issue apparently. - When I'm compressing my .pak file and build the mod for this game, the .pak file turns out to be just 1kb in size.. basically nothing in it. Looks like it doesn't actually cook any of my assets. The moment I uncheck the compress .pak file, it cooks the mod which turns out to be 2.4gb..

Is there any possible way to fix this? I've asked on the mod discord for the game I'm making the mod for, but they don't seem to have an answer. It is also on an old version of UE4, as it's on UE4.15.

[plush yew]

How to fix that error and how to make the bullets go to the crosshair place

[rotund sorrel]

don't know how

anyway this is basically motion blur, isn't there just a simpler way to apply motion blur only to specific characters?

[proud abyss]

Hey guys, merry chistmas. Hope on of you can give me the gift of knowledge today...

I have a skateboard pawn set up thats fully controlled by physics and forces for movement. My question is, i have an input programmed that when i release left thumbstick down the skateboard will ollie. Is there a way to have it so if i was to hold down and then rotate the stick round to either left or right i could make the board rotate accordingly

[rotund sorrel]

In the end i took this material here: https://docs.unrealengine.com/5.1/en-US/using-radial-motion-blur-in-unreal-engine/ Duplicated the mesh of the character( parented to the original one) and scaled it a bit bigger, then applied the material to it. It ain't perfect but i mean, it's blur

[clever marsh]

Hi ,when I import Character mesh from Mixamo to Unreal Engine 4 .... My Character Texture quality Became low, How to Solve .?? Thank you

[haughty steppe]

When is it recommended to stick with the built-in damage system? Looks overcomplicated for my needs
I guess it is done for a reason

[tribal basin]

I now have two different buttons in the menu, for example, when I press the a button, the camera on the right is on the left when I press the b button.

[pallid olive]

hi the character has the same animation if its moving forward as moving right?

its identical as the 3rd person template

the setup, input and controls

why doesnt turn right when movingright

[drowsy snow]

Built in damage system is just yet another interface carrying float (but applied to Actor)

[cyan cargo]

Is there a tutorial or link to show how to properly use the FloatingPawnMovement component? I am using it on a pawn and cant' seem to get it to work at all

[boreal crown]

Is there any way to set the max cache for ddc above 2gb?

[real heath]

.... It has a max of 2gb? Mines MUCH larger than that

Just googled, that limit only applies to the boot.ddc, it shouldn't limit your actual ddc

[boreal crown]

Ah, yea my boot limit needs to be larger (i think) as it's literally taking 3 minutes to boot my project

unless there's an easier way to cut down on that

[drowsy snow]

SSD?

[boreal crown]

No it’s the project. We’ve got SSDs. It loads/imports/verifies loadssss of files

Given the nature of the project there’s over 500 widgets alone. (Not my decision)

[real heath]

honestly, it's not the number of assets, it would be the asset reference chain. Asset A hard ref's asset B. Theres a reason you are meant to use soft references where possible

[boreal crown]

Why would that effect editor startup loading if it loads to an empty map?

[real heath]

IF your startup map references your game mode, which references the player controller, which references the pawn and the hud, which both reference models and textures... and so on and so forth

a very simple map can load TONS of stuff with a poor asset reference chain

[boreal crown]

Oh no it’s a blank map with no game mode

[real heath]

then a larger boot.ddc wouldn't affect loading performance

[boreal crown]

The only thing that’s in use would be the game instance which is a project setting

[real heath]

make sure you use the profling tools to see whats loaded on a blank editor launch

you'll see all the assets that haven been loaded

[boreal crown]

I’ll try that!

Is there a special command needed so that it does the profiling on startup?

[real heath]

you probably don't need to trace on startup, you can see whats loaded now i think

not in front of my machine, so can't check what it is

[boreal crown]

No worries! I’ll look into it

[snow crown]

Remember this?
I'm having trouble learning how to use this TransformVector node properly.
Do you know where it should be placed in that material, and the Source & Destination settings it/they should have?
Or just any insights appreciated.

The idea of the material was to rotate a mesh to whatever the input rotator params (the X, Y, and Z scalars) dictated, regardless of the mesh's actual rotation.
(You had pointed out that the mesh's rotation would upset the earlier material graph image I'd posted, which is true.)

Hi when I import Character mesh from Mixamo to ue4 .... My Character Texture quality Became low, How to Solve .?? Thank you

[plush yew]

its not low quality. when you import materials from mixamo, they are all opaque. you need to change that. like those eye lashes etc should use opacity mask.

theres probably gazillion tutorials online on that topic

[royal arrow]

Is there a setting that makes frustum culling occlude meshes that are hidden behind static meshes? Or is that done by default? While in an underground dungeon in my game, completely blocked off visually from the rest of the game world, when looking toward the mainland of the game, my FPS tanks. Any idea why this would be the case?

[real heath]

It should be done by default, but if your bounding boxes are oversized it can hamper it

Your lights could have insane influence radiuses which would also tank frame rate

But that's shooting in the dark. Run the gpu profiler, it'll help Understanf

[royal arrow]

Okay, cool. Thanks

[sage coral]

Not sure what I did wrong this is a re-target issue that much I know, Im going from a rigify rig to the normal ue4 rig Im just unsure what I need to mark in the retarget menu for the rigify rig so the wrists stop twisting like in the photo

[topaz pine]

Hi can someone help me with learning blueprints?

Any tip

[young crag]

Can I get Link(YouTube) which help to solve my Problem ???

[royal arrow]

You'll need to open the material that imported with Mixamo and plug in the alpha channel into the opacity pin.

[neon wedge]

Yeah, I thought it was kinda obvious

[fair depot]

just use skeleton and animation from mixamo and use your original model for mesh?

Are you using a model from mixamo or your own?

[pallid olive]

Whats better Ai move to or behaviour tree

Overall

[young crag]

I create own character in character creator and import to Mixamo For Skeleton mesh . After that when I import to unreal engine I loss quality 🤕

[stoic stag]

Awesome thanks 👍, I'm already at part 3 of Ryan's. I peek a little bit on Reid's and at 7 min mark it seems he uses a more practical way to interact towards actors using sphere collision. While Ryan's method was using SphereTracing iirc

[floral girder]

Yeah SphereTrace is pretty expensive, best not to use it

You should prob switch over to this one though as it's much easier to iterate and change what you want

Plus easier to make dialogs overall

It uses behavior trees

[stoic stag]

gocha will do 🙂

[sage coral]

Anyone know how to properly retarget an animation for a Rigify Rig to the UE4 Mannequin? I'm using rigify as my control rig and retargeting then to the game rig. Everything seems to work expect for the wrist twist

[pallid olive]

hi how can i hard code weapon equiment without overlapping master weapon collision

everything i try i have a unvalid weapon object

[sage coral]

@pallid olive I reccomend the Remnant from the Shadows Turorial. Itll help you set up picking up/ equipping weapons and animations based on the weapon you are using. They make a data tree in the tutorial that helps validate all the weapon info in a single list makes it easy to change any value if the weapons and of each one. Might help fix the weapon overlapp issue you are having

@pallid olive https://youtube.com/playlist?list=PL3uSxUwLwt-f--gNGVEME84bQsGTTwMO7

This works in both 3rd and 1st person just gonna move some camera stuff around. I have mine working for 1st person

[pallid olive]

hi midgnight thanks for the reply, the idea of this project is the weapons are hard coded so there is no switching in level. i have masterweapon actor, which i made a variable inside character, with the name current weapon, but how can i validate the weapon xd

i have seen that tutorial, great master piece also for multiplayer

maybe structure with all the weapons /?

[sage coral]

@pallid olive same setup should let you hard code the weapons when you start the game 😊

You just need to specify it in the defaults of your character when they spawn what weapons are hard coded and you can eliminate the switching weapons in the environment to have them hard coded

@pallid olive if you use the tutorial you sent you'll have to add the weapon to the master weapon inventory in your playerBP

[pallid olive]

if the actor is like exposed on spawn, i can click on the weapon and set that as current weapon, but that is not the case for this type

okee ill look into the playlist

[sage coral]

Ah yea it's not the exposed on spawn that's your issue. The main weapon inventory is not catching your cast for your weapon it seems and just results back as none as if there is no weapon even though you have it set

[pallid olive]

or make a actor component

[sage coral]

Set something up like taking how your weapon spawns of you are using an array for your weapon like in the video and on begin play for your character drag out your array for your weapon and set it with the same weapon node this way it knows you are spawning with a weapon

[pallid olive]

maybe this works

[sage coral]

This helps. So like I said you'll need to make a master weapon array of class in your variables and give the array a list of 1 where you can than set your current weapon to spawn with

When my ue4 project loads I'll send you a screenshot of my setup

Keep your current weapon class tho

Your blue variable is your static mesh and when you make the Purple one that's an array that will justify the weapon itself that needs to spawn. Currently the game thinks you're just spawning in a static mesh and not a skeletal mesh. From how it looks

[pallid olive]

yea that is actuelly a good ideaa, just a class array then spawn actor from class and from return value set as current weapon

[sage coral]

@pallid olive let me know if that worked or not 🙂

@pallid olive just to help you out some more heres my setup

this is how I spawn weapons in at the start of my game

Zoomed in so you can actually read it

[pallid olive]

yes oke really appreacited thought that was best way, tried to do master object instead class

thanks brother

[sage coral]

Anytime, Happy to Help 😄

[fast trellis]

Are imported static meshes outside of a blueprint / static mesh component not capable of generating overlap events?

Like if someone drops some in a level there is no way to generate overlaps?

How would you access it?

generate overlaps

eh ok, so you would need to loop through everything and set it if it hasn't been I suppose

[zealous ginkgo]

hey slackers ive tried retargeting my skele to two different assets ALS and FCS and both my armpits come out all open lol

[plush yew]

i hast figured it out

[steel pasture]

This is a very advance thing i used this for my personal projects to

[clever marsh]

do you guys have any tutorials or tips for a really really good 3rd person camera system and making my movement feel more AAA and like a lot better, I have a gam jam due in like less than a week and i need a clutch tutorial to make my game feel nicer

ik thats not something you can really just get a tutorial for but really any quick fixes that will make the game feel good are welcome, I don't really know what to do abt the situation otherwise, it feels too much like the 3rd person template and not like an actual game lol

[drowsy snow]

> movement feel more AAA
> game jam

nope

simpler movement system is more excusable for game jam, given the time frames. You can add it later in post-jam update or remaking it for full release

[clever marsh]

yeah i mean just like giving the movement weight, and not feeling like the thirdperson template\

[remote hound]

Hey does anyone in here have any idea on how to convert a map from UE1 to UE4?

[clever marsh]

i know a lot of that is snd effects and camera movement but im not really sure how to approach it

i just want the movement to be more satisfying

[drowsy snow]

That'll comes down to the animations you're using, which is not something UE specific tutorial will cover.

[clever marsh]

well i have some pretty good animations, but it still kind of feels weightless

[drowsy snow]

Remake it yourself by hand, and don't crosspost.

[clever marsh]

might just be me nitpicking or my low poly models but im not sure what the problem is

[drowsy snow]

Are you making your own animations?

[remote hound]

Those are different questions

[drowsy snow]

Nope.

[remote hound]

How are they not different, they're different engines

Ue4 And ue5

And i haven't asked for no one to patronize me

I've asked if someone knows how to port it

[drowsy snow]

UE5 is pretty much the same as UE4 as far as the basics goes.

[remote hound]

Well tell that to epic games

[clever marsh]

i have someone on my team making them

well usually i would but it doesnt really work with the type of game im making

[drowsy snow]

Also FWIW the "weight" of the animation comes down to the animation itself more so than the technical side of it

Play around with the interpolation, tweening, squash and stretch, those good stuff

[clever marsh]

okay

thanks

[jade surge]

Cast nodes automatically load things into memory correct?

https://i.gyazo.com/f32eb78df7c63ed1fd80a94fb7a0ddd2.png
The soft reference is completely redundant because I have a cast node here

right so if I wanted something to never be loaded until it was needed, I should probably make sure it's not being casted, or hard referenced anywhere else in the project

and in other words, utilizing soft references is kind of an all in thing, because it's completely redundant if something else creates a hard reference of it anywhere else 🤔

how are you suppose to keep track of that lol

I have this beautiful problem right now where 32 gb is almost not enough ram to load the project smh

thanks anyway

Okay so then I should, in fact, use interfaces in instances where I don't want to risk loading something into memory that might not ever be needed

I didn't know if it'd be a good idea to use interfaces for this reason

[real heath]

As Laura said, good class hierarchy design with base classes like BP_Enemy that doesn't actually hold any asset references, and the only classes that reference assets don't add any functionality you'd need to cast for

[jade surge]

Lol don't worry Laura, I fully understood what you meant. I was clarifying though that it is okay to utilize interfaces for such cases. @real heath Thank you as well for being more specific about it. It does seem like a hard thing to accomplish though

The base character and controller are filled with asset references 🤦‍♂️

[real heath]

Not especially. Hard/annoying to change after the fact. But if you approach it like that it's not so bad

[glacial arch]

Hey guys, maybe you know whats up. I'm packaging my project and it seems to just get stuck at PCH.OodleDataCompressionFormat.cpp

[warm stirrup]

Hey gang, have a general question about Character Controller Classes. Is there a way to change it dynamically during runtime?

Situation: I have a plugin I bought with it's own Controller Class, and I also coded one myself for my game's stealth mechanics. The features aren't used in conjunction with each other, but are in the same level. So trying to figure out the best way to do this that is not trying to merge them together.

[vital fox]

Just reinstalled windows, I have my UE4 projects saved on another SSD but I don't remember exactly what version of ue4 I was using. Is there anyway to find out just from the project files before I install the editor?

[vital fox]

Ok. Just worried about depreciated stuff not working or something. My projects aren't too big so not a big issue if I have to fix stuff

Hey! I want this interface message to send this data to the level it is currently in, what would the target be in this case? I can't figure out how to get a reference to the level it is in.

[raw oak]

Don't think you can do that. Level blueprint isn't great to use in general. You could use an even dispatcher and bind it in your level blueprint

[floral girder]

Im having a UI change the state of the level/objects in a streamed level outside of the main level, so the object that you use to enter this level is no longer there and can no longer be accessed, so I have to figure out how to send the data aquired from that actor to go to the level and the UI.

[rotund sorrel]

How can i see the absolute height and width(in cm) of meshes in unreal?i don't mean the scale ofc

Hey all, I'm a UI designer looking to get more well versed with UI animation best practices in UE4. I'm trying to understand how folks accomplish UI VFX, whether that is done via UMG animation timeline, flipbook, materials, or other methods. I'm looking around for tutorials or discussions on best practice but have yet to find much. In the project I'm involved with I have seen all of them being used. I'm really curious how often flipbook is used for UI. Seems the workflow is using a tool like AE to animate, then export a sequence of images and import as a "sprite sheet", then turn that into a flipbook via UI material, but how do you deal with frame rate and are there performance concerns? It also seems the UMG timeline wouldn't be great for everything, since you don't have access to as many tools as you do in a motion software like AE.

Here's an example of a UI animation that I'm wondering how it was accomplished (via https://www.artstation.com/artwork/NxGxnD). If this is the wrong channel, I'm happy to move this elsewhere to continue the discussion.

[drowsy snow]

You can do lots of things with materials and the standard UMG sequencer techniques. There's also Niagara to UI plugin that allows you to put in 2D Niagara particles in the UI renderer

No idea if anyone can helpe me but any info helps. Im having a retargeting issue going from a Rigify rig to ue4 game rig, I seem to have most settings right but for some reason its offsetting the hands so I defo messed up somewhere with the settings, Ill post my Retarget settings aswell

Sorry for all the pictures I wish there was a way of making the menu bigger in ue4 so I didnt have to splice the photos up

[fluid fable]

Does anyone have experience with top down games, more specifically with mouse controls?

[buoyant granite]

:question: Can I ask a question?
Don't ask to ask. Just ask!

[fluid fable]

Okay so I want my character to move forward when you click and hold the left mouse button. I have it so they turn wherever the cursor goes, but I can't figure out how to get them to actually move

[candid grove]

https://www.youtube.com/watch?v=xkY8xqwmyFU&ab_channel=MathewWadstein maybe that'll help you?

[fluid fable]

Thank you! I'll check it out

[fluid fable]

This is what I found

[short cipher]

I want to create a UI that explains how to operate like this image. But I don't know how.
My game allows you to change the operation method in the settings. So, if you change the button layout in the settings, I would like to create something that also adapts the UI.
Is there a BP that calls the arrangement of keys created in UE4's input?

If player change the button layout, the notation of the UI will also change. this is my ideal

[stark talon]

@shy nacelle do you remember the flash issues i had when moving the ISM in the WPO? The problem was solved by removing motion blur and anti-aliasing.

[hidden dew]

:/ Using a HISM and lots of grass is reliably crashing my video card

I guess it's overheating, but it only gets to 80°C at the most so far

Which is a fair bit, but Apex will sit at 83° forever with no issue

[royal arrow]

In an open world game would removing unnecessary components from your landscape help performance? We have a lot of ocean covering dozens of components players can never reach. Is that costing us performance or is it better to have a square landscape?

[vast totem]

For levels like these, would you use landscape editor or just a crapton of textured cubes? Obviously I'm new but neither of those options seem particularly efficient

[real heath]

Neither? You'd probably block out the level with cube grid or modelling tools plugin. Split the mesh appropriately so meshes aren't too large. See how far that gets you

[vast totem]

Thank you! I wasn't sure if there was something like that but sounds way better, I'll try it out.

[lament basin]

Can you convert a 3d rope object into a cable? or any kind of objects into cable

[honest vale]

yea definitely not the landcape editor, it can't do vertical faces

[rain badger]

Does anyone know why/how to fix the assets in my vault not displaying their thumbnails? When I go to my library and check the vault they are just displaying white boxes instead of the image of what the asset is

[boreal crown]

Hi, my editor takes literal minutes to open certain bps and widgets because I've got a bunch of BPs that are GBs in size due to the assets in them (this cannot be changed). And any widget or BP that references these large BPs take forever to load because I guess the editor loads it all into memory, so my size maps for my widgets are in the gigabytes in size. How do I cut down on this so things open quickly?

[real heath]

Soft references and do async loads

[boreal crown]

@real heath true. But how would I handle datatables that have references to all the things? As those load slowly as well. Can those use soft refs?

[real heath]

Probably? Or at the very worst, paths. Thing is you are experiencing problems as a developer, how are end users going to go with a lesser system? You really have to pay careful and close attention to asset chains to prevent long loads and excess memory usage

If data tables don’t work with soft refs (they should since it’s just a struct) then consider another architecture for how you reference assets

[plush yew]

they do work. i highly recommend 😄

not fun to load 20GB dt..

[robust marten]

Is there any way to reduce the size of my project? I've loaded only a few assets and my project is quickly creeping up towards close to 100gb in size lol

[plush yew]

lol

[pallid olive]

hello, has someone an idea how to make a moving projectile, (bullet) ignore its instagator ?

[boreal crown]

I feel like this is a dumb question but is it possible to put a normal pointer into an array of soft pointers? Like is there a cast or something?

[spice ruin]

You can convert the normal pointer into a soft pointer to add it to the array (probably) if they are they point to the same type?

[boreal crown]

They are the same type. How would I do that though? Cast(TSoftObjectPtr<whatever>()?

[spice ruin]

YourArray.Add(yourpointer) might just work with an implicit conversion

Or YourArray.Add(TSoftObjectPtr<type>(yourpointer))

[rough tusk]

hey guys, is anyone experienced with the variant manager?

I have a simple question

[spice ruin]

https://dontasktoask.com/

[rough tusk]

@shy nacelle , @spice ruin ,ok so actually i would like to know if it is possible in the variant seleciton, when i have multiple actors, to proceed subsequently with the actions i have chosen. Not directly all of them

I dont even know if it makes sense

in example, I need to activate another camera but only after i have finished blending to the camera, I want to change a material

not at the same time

[sage coral]

might be a dumb question but is there any way to hide unused pins in a node

Ill use a screenshot as an example

The screenshots a Save Game and all those bools are stored in a split Structure, Was just curious if there is a way to hide the pins without recombining all of them?

[strange bear]

Do Texture2DArrays not exist in 4.27? It's not under material & textures?

[empty sage]

Is there a way to know if a BP graph is running in the editor without PIE? e.g. running from a blutility

[drowsy snow]

Not without some C++ to check for editor (and selectively use #if WITH_EDITOR macro)

[hollow socket]

Has anyone figured out a way to use hand tracking over Airlink yet? I have see a few mentions of OpenXR now being able to do it, but no confirmation.

[eternal cobalt]

Would there possibly be a way to nativize BP into C++ without it being so illegible and spaghetti-like inorder to learn what functions are being called and what is being used in the unreal library?

[real heath]

Double click nodes should bring up the source code if you have a c++ project. Also I think 5.1 has header preview so you can see what a function declaration should look like in c++

[verbal pulsar]

Do game user settings transfer between levels?
