ue4-general

[limber mesa]

3k,2k,1.2k and 100 didn’t work

Wow I set it to 5k and now I’m at 97%

What’s the most optimum range?

[plush yew]

why does everyone ignore me i just need help with rigging and importing

in this rig when i import it to ue4, the eyes and mouth don't even import and the bottom 2 feet import as separate skeletal meshes and objects

okay so the eyes and mouth are importing now but one eye has inverted normals

like wtf

this some bullshit man

How can I open a uax file? Everything online says they're from Unreal Engine, but I get "Unknown extension 'uax'" when I drag it in

I am working on a student animated film in Unreal and I am trying to render a specular reflection render pass , isolated from the rest, so that I can modify it in Nuke afterward, but for some reason, the render is a complete grey screen and I have no clue what I am doing wrong. Is there a setting I am missing in order to rectify this issue? thank you !

[versed lichen]

Cannot remember how to snap a spline point to a vert. Holding V doesn’t work. What am I missing?

[dusk nebula]

Hey, what's a good way to record distance traveled? Like, I want it to be able to count forwards and backwards and just add the linear distance to some variable to track it

[lean cloak]

Hey everyone, I need help regarding texture control in Unreal:

I notice the streaming pool goes over budget constantly especially in converting meshes and lights to movable fast. I notice in other render engines like blender for example don’t do that. So is there a way to stop it from forever rising?? It’s really annoying tbh just because I want a full dynamic scene like you normally would have in your standard render engines and not have to worry about texture rising on your Ram constantly in even such a simple scene setup

I’m in UE5. I know we can use the command for increasing streaming pool but it keeps rising and I’m only using one mesh with 4K texture and sky light setup.

Are there any settings to sharpen the details further if it already says the max size of the texture is being displayed?

And do I need to turn off streaming by turning the rstreamingpoolsize to 0 so I can have it act as a regular render? Or will it still keep increasing infinitely? I just want the quality to remain and stop increasing. I have 11gb of Vram but I would rather use my 64GB of Ram so it won’t run out for sure

[plush yew]

ok this is dumb but how would i give a mesh(like a cube) keyboard inputs on the blank template?

actually how do i give a character parent class inputs like keyboard

[neon bough]

by possessing it^

[plush yew]

i cant tell if your joking

[prime willow]

so my mesh is stuck being rotated based on camera angle

and i cnt seem to undo it :/

[bleak widget]

hi guys! i want to move pawn by physics. Is possible? AddForce applying but nothing is done

i using Pawn

[burnt iron]

@bleak widget hey andery, maybe you should try doing it C++ way

https://forums.unrealengine.com/t/physics-pushing-a-pawn-that-uses-navigation/2965/3

you could ofc expose the function to blueprint and easily call it when certain event emits

but it describe override, so try from here

UCharacterMovementComponent::CalcVelocity()

[bleak widget]

so i still should trying BP only

[burnt iron]

why though?

[bleak widget]

i want like this https://youtu.be/QvcBotEg6ds

[burnt iron]

ok, still. don't understand what you said you still should trying bp only

[bleak widget]

C++ way will cause difficulties

[burnt iron]

ok

there might not be a way, check the comment of the staff memeber on the link i sent here

[fleet sparrow]

For Mesh Merge do all the components must have same materials?

[bleak widget]

Okay, I will consider all options

[untold summit]

on a sidenote, making the game exactly in the given daten might not happen if streaming becomes too much of an influence in my life.

because that takes a much bigger priority.

[hidden dew]

Damn just when I thought I understand collision channels, I add 1 new trace channel defaulting to ignore, and put it on a line trace I don't even use....

... and everything breaks.

I delete the trace channel and everything's fixed again.

Well that's a puzzle. The one place that even calls a line trace with that channel is in a blueprint that is on no actors in the level.

[violet pilot]

Anyone know if it's possible to make the Cesium model not receive shadows?

[neon bough]

collision channels can be a pain sometimes, best bet is to restart the engine after changing them

Hi people! i have a question. I'm thinking of making a silent hill type game. but ive spend i week thinking how i would make the gameplay work. anyone has any tips? or maybe something in the store, or a projext build somewhere

[delicate kayak]

Anyone know how I can remove the head of the basic unreal model because I want to convert the 3rd person preset into 1st person

[modest trench]

try shrinking the head bone

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Components/SkinnedMesh/HideBonebyName/

or hide I guess

[delicate kayak]

It worked kinda

[modest trench]

you could have a second mesh just for shadowcasting 😛

with the visible first one not casting shadows

[delicate kayak]

okay ill give that a go

thank you

how do i make it not visible and still cast shadows?

found it

😀

[violet yoke]

Hi, so I have a problem adding materials in ue4. I imported the model but parts are parented and I cant assign materials to every individual piece. How can I brake these parts individually? In blender all the pieces are parented to the armature. For example, the select piece is made of 3 planks but all of them are as one single mesh

[timid creek]

@delicate kayak For those who didn't find it, there's an option called "Set Cast Hidden Shadow" which can be set in the blueprint or at runtime.

[plush yew]

I installed the automative materials pack thing for unreal and opened the map in it, but its all white, what do I do? (I dont use unreal I just need to view these materials in unreal for a client project)

[mystic wren]

Does anyone have a idea?

[modest trench]

Too vague a question

There are horror game assets on the marketplace but I can't speak for their quality

Or if any of them do exactly what you want

[valid perch]

I want to build a train track and how can I make the object copy itself with the blueprint?

Really hard to give advice besides to try to break the problem down into smaller pieces first

[drowsy snow]

And you get Silent Hill Homecoming.

[mystic wren]

Yeah kinda

[drowsy snow]

So... What's your problem then?

[modest trench]

Go make the game!!!!!

[mystic wren]

Yeah i'm not that experienced using ue4, but what i'm trying to to to be honest is. having a gameplay style like the advanced locomotive system. combined with horror engine

[valid perch]

I tried, but it doesn't work correctly even though I did exactly what is in the video I watched.

[drowsy snow]

Just do it.
Don't let your dreams be memes.

[patent cobalt]

Is it only me or blueprintUE is unable to properly render a Blueprint?!?

@valid perch I would rather look at a real screenshot of your code

LOL

including the execution lines that look like a printed circuit board

[drowsy snow]

To be fair, it's more of a "clean room" reverse engineering of the BP graph system.

[patent cobalt]

@drowsy snowtrue but it needs some decent work honestly. I thought they got an Epic Mega-grant.

[drowsy snow]

Well, I thought Epic MegaGrant only go as far as providing funding, and not actual support/manpower...

[patent cobalt]

So it is take the money and run with it?

With all due respect for the developers of the site.

@valid perchwhich tut have you been following?

[drowsy snow]

Well granted (all puns intended) I don't know exactly how the MegaGrants works, so yeah...

[raw anchor]

Hello. Scaled a character way up to giant size but when it runs . It does not cover the distance like a giant. It runs and covers distance just like any Regular sized character. How can I make it that the giant runs but covers more area like a giant would?

[exotic thicket]

Maybe try multiplying its speed with the scale?

Either way it's just a question of adjusting the movement speed

[raw anchor]

@exotic thicket tried that from some tutorials but does not seem to make the appearance of the giant moving and a giant pace

[icy plaza]

I try to find some infromation regarding triggering events. I want to use a few trigger boxes that would make the scale of a different blue print actor grow. Does someone has some information regarding this?

[dry birch]

ue4 compression broken?

it does not compress at all, same size as before packaging

[exotic thicket]

How much something compresses depends entirely on what it is. For example, a PNG image does not compress much. I highly doubt that UE's compression was broken because it would affect literally every game being developed on it :P

[dry birch]

No not that

my game used to compress so much!

now it does not

there is something broken, perhaps we can say it is broken now?

[exotic thicket]

I've noticed that you seem to assume your problems exist because something in the engine is broken... I saw you ask a question with a similar assumption previously

[dry birch]

is the execlude content editor files safe to tick?

yes, there is something has been changed

[exotic thicket]

It's best to not immediately assume the engine is broken in such fundamental ways

[dry birch]

in the settings

im not saying the engine is broken, don't make words on me. that's... quite uncomfortable.

im just trying to say there is something off

what is so hard for you to understand?

:/

[exotic thicket]

I've just seen a lot of people assume the problem is in the tools they're using (such as UE4 itself) and not in their own code

and the problem is almost always in their own code

[dry birch]

i have no code, it is packaging settings im reffering to, not the code or the whole engine

[trim mantle]

You literally said this xD

[gaunt abyss]

Umm you yourself are implying that something in the engine is broken 🤔

[dry birch]

i have no code, it is packaging settings im reffering to, not the whole engine

sorry cant say it propleply

let me repharse it

perhaprs u might udnerastnd better

my compression for some reason is off not work correctly

is that ^ clear? please dont make words on me, thanks

[exotic thicket]

Nobody is trying to put words into your mouth, we're just trying to help us help you :)

And yes, that explanation of the problem is much better

[dry birch]

apprecaite it ❤️

I have a blueprint that is zoomed out and repositioned so much that I can't actually find the nodes on it

How do I re-centre it?

Ah, found a way

Graphs -> Event Graph -> double click anything there

[zinc cipher]

I don't know where this would fit. My artist uses a Wacom Intuos4 PTK-840 which is a drawing tablet. He often plays with the drawing pen (but he also has a mouse for the tablet). With the default FPS template (and our own FPS character blueprint), he cannot rotate more than 180 degrees in a single move. Like if you move the mouse you keep rotating around. Using the tablet, it stops. And he has to release and start again. I know it's SUPER edge case, but anyone have any idea what's up?

[sullen tree]

Guys, where can I ask for help about ue4?

[grim ore]

probably in the game devs support channels. if you mean UE4? then pick an appropriate channel

I'm trying to rotate an actor so that a specific socket on the actor's mesh is looking at a target
"Find Look At Rotation" will find the rotation for either the socket or the actor but converting the socket look at rotation into an actor rotation is just breaking my brain today

[hollow moat]

Does Unreal have any built in button images?

Like X for Xbox
or Square for PS4

Or will I have to create those myself?

[fierce tulip]

you can find templates for them online. google search should help

[hollow moat]

I found some nice ones!

https://thoseawesomeguys.com/prompts/

I went with these

[tired abyss]

What's the correct terminology for converting numbers to smaller versions and prefixing them with things like "k" for thousand, "m" for million etc

[hollow moat]

Abbreviating?

1M is an abbreviation of 1,000,000

[tired abyss]

Ah yes thank you omg

Brain no work

[hollow moat]

No problem 😛

[tired abyss]

Wait before I go and implement this, am I going crazy or do I remember the engine having formatting built in to do it?

[hollow moat]

I had a look on google and it doesn't look like it!

@tired abyss please share your implementation when you're done though?

[tired abyss]

Oh nvm I am thinking of ToText(float) function that has some formatting built in

Dam mike you beat me too it 😠

[thorny moon]

I accidentally pressed something and now I can't control my pawn or click anything in the viewport. The white line appeared after I pressed something.

if you ever get that again

you can just drag something like message log or ouput log into that window

[spare kernel]

no?

[prime willow]

oh

thought snowie did a bad ;-;

[rugged arch]

I tried learning unreal but I found that most tutorials uses blueprint instead of c++ why is that?

[grim ore]

because

blueprints are part of the engine, its how most things are interfaced. C++ is not a requirement and also... if you know C++, you have the ability to learn unguided most of the time with how C++ works in UE4

generally life finds a way, the audience for C++ "learning" matches the amount of C++ material you find out there

[plush yew]

man i cant believ that remasterd gta using unreal engine

[spare kernel]

Also a game will use both C++ and Blueprint

they work together.

@plush yew why? sure you mentioned this before also.

Is it bad that they used UE4?

[plush yew]

yes

cuz rage engine is fine

[spare kernel]

clearly it wasn't or they would have used it..

[open eagle]

^^^

The developers certainly know more than you do for this kind of thing

[plush yew]

am also shocked how they could port car physx to unreal that good

[spare kernel]

again why?

they have a big team of talented people.

[plush yew]

cuz this means there are tools that can be used in unreal are private to a company even though unreal is available to end user.

i guess grove street game dev company knows ue4 secrets

[grim ore]

it might surprise you to know there are tools that epic themselves uses that are private to themselves...

[plush yew]

Z:\GTA III - Definitive Edition\Gameface\Content\rageunreal\gta3

well the tools is rage unreal , maybe a bridge between rage engine and unreal ?

[rugged arch]

I wanna learn unreal but I have no idea how or where to get started I took a look into unreal tutorials but I didn't know what should I learn first?

[terse trench]

HI there is there any good tutorials on Unreal C++ cause I am trying to find some good ones. That get into like all the detail and explains everything

[grim ore]

start with the intro and beginning tutorials on the official learn.unrealengine.com site @rugged arch

There are learning paths on the official site like this one https://www.unrealengine.com/en-US/onlinelearning-courses/welcome-to-game-development which gives you multiple courses in an order

[gaunt abyss]

It's probably their own custom UE4 engine branch, most bigger and serious projects will have their own custom branch of the engine
Not that surprising

Also I don't see a reason why they wouldn't be able to port stuff like vehicle physics to UE

[idle mantle]

Hello I saw the new that Unity bought Weta

im very surprising that UE didn't bought it instead

so Unity own WetaH and WetaM?

[plush yew]

@gaunt abyssthats it

[drowsy snow]

Here's the thing:
Grove Street Games is actually War Drum Studios, and isn't part of Rockstar's internal studio line up. That's one reason they didn't use RAGE.

[drowsy snow]

Doesn't seem like it.

[drowsy snow]

Probably just as simple as porting the original C++ code into Unreal's renderer, kind of like Demon's Souls remake.

[idle mantle]

I mean UE4 is more intended for movies so it makes more sense what epic buy a film VFX studio lol

this is really weird 🤣

[drowsy snow]

Eh, as far as filmmaking goes, not really. Mandalorian S2 ditched UE4 for the virtual background, replaced by in house solution.

[hollow moat]

How can I make my custom component draw something in the Viewport window?

[distant totem]

I thought the in house solution was a custom version of unreal they built off of called Kona?

[drowsy snow]

IIRC they used ILM's own renderer, called Helios or something

https://www.fxguide.com/fxfeatured/mandalorian-season-2-virtual-production-innovations/

They still used Unreal but just for previz and not for actual background uses

[distant totem]

ahh yes I see, wonder what prompted the switch, thanks for the link 🙂

[drowsy snow]

Probably they just use UE4 to test the water.

Well, not testing the water system, but you get my drift.

[prime willow]

[grave pollen]

do spline points have to be directly on the nav mesh ?

my AI is not able to follow the path (some make it some dont), albeit its a long one with twists and turns. I've tried everything... I changed cell height, cell size, nav agent height , step height, walkable floor angle, re-did my nav mesh, then made 2 more nav meshes so there's 3 now.... yet they still have issues in certain areas and I cannot solve this. Appreciate any help ty

[drowsy snow]

You can. Just migrate the asset from the new project to your project's Content folder. Unreal has a handy feature to migrate assets without breaking references to related assets, so no need to manually copy paste them in File Explorer.

[autumn flame]

Pretty sure all those assets are on Bridge anyways too

[hollow moat]

My Blueprint implements an interface

But when I try and cast the actor, it returns false

IInteractable* interactable = Cast<IInteractable>(hitResult.GetActor())```

[plush yew]

@drowsy snow Thanks!

[spare kernel]

@hollow moat you need to add the interface in c++ to use cast on it.

which is why with BP interfaces, you use BPNative/BPImplementable events

[hollow moat]

It's all working now

Thanks though 🙂

[spare kernel]

and do if (HitResult.GetActor()->Implements<UInteractable>()) { IInteractable::Execute_SomeNativeEvent(HitResult.GetActor()); } FYI

if its a BP Interface

[astral dust]

Hello, i have a question. I would like to take anti piracy measures for my game. Although, I don't know how to get started with that

[drowsy snow]

If you can't afford Denuvo, don't bother.

[astral dust]

I've heard Denuvo has major performance impacts on the game, so i don't think its a good idea either way

[drowsy snow]

I'd say don't even think about the pirates. There are few reasons that aren't inherently criminal behind a pirating person, like region lock, financial troubles, protest of a business model, or just want to try it before actually buy it. If your game is good, people will buy it, even if it's later than sooner.

Provide a playable demo, that'll at least help shape someone's opinion on your game, and measure their expectation with the hardware they use.

DRM can only deter piracy for few weeks top, and can unnecessarily hurt legitimate users in the process. If you're a AAA dev and want to secure a quarter's sale, then sure, put a Denuvo or other kind of DRM. If you're a small time indie, then better let the word of mouth do its thing.

[lucid grove]

Hey guys, can figure out how to achieve this:

I have MAP variable (TaskID-to-QuestID) with TaskID and QuestID.
I want somehow loop all this map and get all TaskID that equal to QuestID.

TaskID is unique, but QuestID is equal to quests its assigned to.

Its simple when i worked with arrays, but same approach doesn't work with map.

[marsh canopy]

I had downloaded ue.4.25

So I started downloading in ssd then after sometimes time paused and closed it and pasted all files their

It worked before

but this time after verfying and cleaning up It tried to download last 40 mb

but it is not able to connect to network

It says error is because of no internet but my internet is running fine

[tender pecan]

you can try #audio \0/

[tender pecan]

\0/ I downloaded 4.11, 4.21 and 4.26 yesterday and it worked fine, maybe delete your vaultcache, and cleanup all residual installation/downloaded files, make 100% sure you have enough space and just try again I imagine.

sometimes the launcher gets confused about internet, it happens, you just have to force close it and reopen it. it can also happen if your internet drops, it wont always pick up and auto reconnect, it just happens sometimes.
there is no substitute for bad connectivity checking code 😆

[neon magnet]

okay but I thought since this it's more active here I'll try first

[tender pecan]

no problems, I have no clue what you are talking about so cant help you im afraid

usually if no one answers, that speaks volumes

[neon magnet]

could be that people miss it due to other messages

[tender pecan]

also possible. but your question does seem very related to audio, and they are pretty clued up there

[neon magnet]

but like it's helpful if people say anything, even if they don't know. Otherwise you're not sure if it was even read or acknowledged etc. Anyway I've asked in the audio section now but it's usually really really quiet there lol

(btw I posted an image in the audio section which illustrates what I mean as you said you didn't understand what I was talking about)

[drowsy snow]

Well, firstly, I don't understand your question, so I can't speak volume. Secondly, #audio actually has the expert on their fields, but this is the sleeping time for the western time zones.

[neon magnet]

the question is to do with general UE editor behaviour rather than specifically with sound logic/interaction/etc. this is why I thought to start in this general forum first. What I was asking was if anyone knew why I cannot see these flow lines (in red) when I play my cues. Since I can see these lines if I am in a regular blueprint, this has me confused

anyway, in another thing, I was wondering how I can implement this better where I want to play a sound when I collide with something at speed

The problem is that this often plays the sound too many times if say I keep running against the door after the first impact (i.e. not going back but just keep running in the direction of the door)

using that seems to play it more often when I move back away after hitting it lol, so weird

(yes begin overlap not end overlap!)

it's like this

I just wanted collision sound if I bump into it so hadn't thought of open or closed - ideally it should play whenever I bang into it. Later on I could adjust the volume depending on the velocity

I should add that I have a thinner capsule size for various reasons - the default one is just too big for narrow spaces so I dunno if this makes a difference

[plush yew]

why is fps so low? which setting of post process affects it the most? and which balances it out? Room itself was in gold type of color, but I switched it to black and white.

https://www.youtube.com/watch?v=kU6D-goGk-o&t=193s&ab_channel=Nitrogen

im editing settings as in this video

[neon magnet]

check your lights, if they're all casting shadow they will be very expensive

[plush yew]

yeah, original is like this

so basically lower everything before and rise after in post process?

[neon magnet]

I mean check how performance is when you remove casting shadows and enable shadows. Then see which you need and which you don't. Even without shadows, lights on their own are still pretty expensive so it's a lot of fine tuning and experimentation to see what you need and what you don't. Maybe use two lights for lighting and the rest you can use an emissive material?

[plush yew]

yeah, will try

thx

[hot thistle]

Anyone else ever had a bug with the NavMesh not working? Its working as usual in a empty level, but in my main level it wont show up, nor does it spawn a Recast?
P doesnt show it either

[patent cobalt]

@hot thistlea navmesh needs collisions to work with. Does you floor have collisions?

[hot thistle]

Yes, its a standard landscape - even tried making a fresh one, seems like it wont work particualrly in this level

[patent cobalt]

engine version?

[hot thistle]

@patent cobalt 4.26

[patent cobalt]

Do you have sub-levels?

Or is the navmesh in the persistent level?

[hot thistle]

Yea, but tried putting nav mesh in all levels, still nothing

What is weird is that its not creating a RecastNavMesh actor

[patent cobalt]

ok, anything in the log? any warning/error?

[hot thistle]

Nothing

[patent cobalt]

you can try to export that level to a fresh project and check if it still does it there

just to single out where the problem could be

I assume you have Build all nav data for the level

[hot thistle]

Its a TwinMotion / Datasmith import, maybe that has something to do with it?

[patent cobalt]

oh, so it is not an Unreal landscape

[hot thistle]

the landscape is unreal

[patent cobalt]

ok, then it shouldn't matter

unless you have something big in it with collisions enabled which may be confusing the navigation system

for example you have a huge cube around your landscape and you are inside of it

it may be worth duplicating that level, removing everything except the landscape and see if it works in that way

I have seen cases where someone accidentally turned on collisions for the skysphere and everything in the level didn't work properly until it was solved

[violet yoke]

Hello

So I want to make a survival game , Im at start with ue4 and I cant find any good tutorial series on yt

What should I do?

@patent cobalt so I got a recastnavmesh now, but still no visual navmesh

[fallen marten]

@violet yoke If you are just starting, then i would start simpler thana survival game dude

[violet yoke]

Ive been prototyping a car game

And learned some things about the structure of a game

How materials work, how to add collision to imported mesh

And more but Im not the best at blueprints

[fallen marten]

Ok, well, then there are a shit ton of tuts available - ike this one was first on a google search - https://youtu.be/maG2YnVnIVM

[fallen marten]

I was wondering if anyone knows how to get the Physical material of a material from a line trace - i cant get anything except the PM of the physics asset or PM override of the Skel mesh

And yes, im using complex collision test

Anyone?

[patent cobalt]

@fallen martenengine version?

try adding the physics material insider the shader instead of overriding it

[fallen marten]

its 4.26, and yeah i added phys materials in the material editor

overriding was just to try force a result

[cinder flare]

anyone use strider plugin

i try to use it with synty character

[patent cobalt]

@fallen martenit should work then. Maybe show how you are doing it.

[cinder flare]

but the strafing so weird

We can also move to #legacy-physics

Anyone can help me fix this inventory something is wrong and I can't fix it
https://www.youtube.com/watch?v=q6S470tLB8k

[honest sand]

Hey, I would appreciate it if someone can maybe help me. So this inventory system I'm using uses a scene capture component to make the character show in the inventory. But its not capturing child actors that's added to the Player Capture Blueprint on begin play. I was wondering if there's a way to make the scene capture, capture the child actors. Or if there's maybe a workaround or something.

[dapper shale]

Is there a way to rotate this video within the Unreal Engine 5 media player?

Tried flipping it externally, stays at same angle.

Externally meaning using other editing apps to flip it.

[drowsy snow]

Maybe HandBrake can rotate the video? Or use Premiere or Shotcut to rotate it.

[neon bough]

maybe turn your screen

or just switch the UV channels

[dapper shale]

It appears that filming in landscape fixes it. Not what I want to do, but, however.

[plain ferry]

Hi, I want to create a camera blueprint with my own class inherited from UCameraComponent. But when I create a ACameraActor, I cannot replace the default camera component by my own. What's the correct workaround here? Should I just create a simple class inheriting from AActor, and put my UCameraComponent in it? I tried that but it doesn't behave as the default ACameraActor, so I'm wondering if it's the correct way to do this.
My goal is to only lock the head orientation to the HMD and not the position, because "Lock to HMD" locks both, and for some reason it moves the camera under the ground.

[dapper shale]

One last thing. Is there a way to increase the size of this video within UE?

[sweet jacinth]

hello, is there a way to make a blueprint actor instead of a static mesh in this specified area or a buleprint actor for the statich mesh added here please because I will add a lot of greenery to my game and these will be usable

[drowsy snow]

What are you using to put the video plate on screen?

[drowsy snow]

Also #virtual-production

[dapper shale]

I'm just using a plane and importing the media. On top of that, I'm making sure the camera is linked to that plane so that it focuses on the video.

Ah mb, let's meet there.

is there a way to make flying paper type of animation in unreal? like fast and easy way

https://www.youtube.com/watch?v=FEDGzNGYzvw&ab_channel=MucanDesignsStudio

like this, but in unreal itself

i guess flying mesh animation, but then again it wouldn't be able to distort itself like in blender

or could it? 😄

[neon bough]

maybe with cloth simulation

but that has some problems with world collision in my experience

[plush yew]

ok

[neon bough]

or rig it

if you rig it you can work with normal physics collisions

and/or animations

[plush yew]

yeah, gonna use blender

just that I am learning it too

thought there might be some easy way in unreal

one way could be using rain animation and replacing rain texture

and adding wind to it

could it work and affect how the rain textures fall down?

[neon bough]

idk if theres a weather interaction, but you can for sure change the velocity vector of the particles

and control that by some external weather thing

but maybe thats already covered by the engine

[plush yew]

ok, thanks

hm im thinking about creating characters where parts a changeable, like change the head for example.
is there any way to fit the neck vertecies to the head inside ue4?

as i creat characters / multible heads i might need to adjust the neck depending on the head or the other way around

[drowsy snow]

No. That's why you make them modular, with morph targets and split skelmeshes.

[unique kraken]

just wanted to say shapekeys are the only solution i can think of.

u got any sources for me?

split skeletal meshes arnt that big of a deal. thats what i planned

but a different head needs to fit a different neck

[lyric falcon]

I'm having a bad time using linetrace and I don't really know whats happening. So, ok, lets suppose we have a door, and when linetrace hits, fires an event of show widget (inside the door BP, there's a widget component). The problem is, I want as soon it stop hits, hides the widget component. The problem is, that as soon It stop hitting, I lost all control over that door, and the widget stay visible. How can I turn off the widget of my door as soon the linetrace (of my character) stop hitting the door?

As I said before, as soon the linetrace stop to hitting, I lost all the control of the door, how can I disable the widget (inside the door) then when I'm not hitting anymore the door?

I tried this:

But it doesnt really work very well

[lyric falcon]

im sorry im very noob at logics

dont understand very well, but anyways, this example

[lyric falcon]

this one

Doesn't work very well because when I duplicate the object, and use the linetrace, the widget get bugged and it keep showing in both objects (even when is not hitting anymore)

how can i do this?

yep thats the problem, it still shows, when it should hide

any idea ? XD

But it doesnt, because the hide node can't execute, because is not hitting anymore

Yes

[lyric falcon]

In this example: This is what happen when you duplicate any object

seems fine right?

but when you hit the duplicated

the widget still shows in the previous one

[hollow cairn]

are you referencing it in your blueprint maybe?

[lyric falcon]

this should be something pretty simple but wow hahahahha

im noob with logics

Hi! No matter what I do, I'm not able to cull my trees in the distance, or even change their detail distances whatsoever. The default LOD distance seems to be way too high by default and I can't seem to figure out where to change it

To clarify; My trees do indeed seem to become billboards and stop rendering shadows a few thousand units away from the camera, so the system seems to be working at least somewhat. It's just changing the culling / detail distance that doesn't seem to work. Changing the max and min cull distance in the Foliage menu doesn't seem to do anything at all, either.

[boreal grotto]

Is there an easy way to install UE?

[drowsy snow]

Yes, via the launcher. That's the easiest way, in fact.

[weak cypress]

I dont think the launcher works

[drowsy snow]

That is implying that you don't have another PC/a friend with existing engine installation.

[weak cypress]

I do

[drowsy snow]

Then you can copy the entire engine folder from one machine to your own.

[weak cypress]

Will it work?

Cause its cross-OS

can you change planar reflection size or use mesh as planar reflection itself?

to circle

[drowsy snow]

Well, the planar reflection volume is what makes a mesh use a planar reflection.

[plush yew]

confused lol

[drowsy snow]

It's as simple as covering a (mostly) flat surface with the planar reflection volume. The preview plane is there to let you know where it's facing.

Just don't think of it going to achieve the same reflection as a raytraced reflections, because it's not going to work well on curved surfaces. It's named planar reflection not without reason.

[plush yew]

oh yeah

got this thx

can it get reflection from far away

like this

i guess not

[dawn gull]

Hey, I'm having some math issues. I'm using this code to spawn in ray casts (https://blueprintue.com/blueprint/aqhvc7sj/), and with the branch before the setworldlocation I was thinking that it would make a circle, or even just not show anything at all because all the values printed out are above 10 but it still just shows a big square of casts

[plush yew]

all i can get

[dawn gull]

even with the branch set at -5000, legit nothing changes.

[sage bane]

@orchid hinge

[silk sleet]

how do you FMatrix * 4-Vector in cpp yall?

FMatrix::TransformFVector4() nvm I'm dumb

[onyx nest]

anyone?

[silk sleet]

are these armor pieces separate meshes that can be bound to a bone on the character?

ie: import everything separately and then re-compose it in BP

[dusk nebula]

How would a game like Destiny 2 handle its characters, where each armor piece has a different texture? Is each piece a component or something? Obviously it's a different engine, but I'm curious if anyone would know how something like that works in UE

[drowsy snow]

I don't play Destiny 2, but clothing pieces can be done with multiple skelmeshes sharing the same skeleton and multiple materials.

[dusk nebula]

So you can map multiple meshes to one skeleton?

I know little about most of the engine's ancillary systems like skeletal meshes, animation, materials, or Niagara

[drowsy snow]

Yes, that's how modular characters were built.

[onyx nest]

i DONT KNOW

welp caps

[modest trench]

Skeletal mesh combining cam be done multiple ways iirc

[dusk nebula]

Where should I start if I want to learn from skeletons to animation? I'm basically just bootlegging everything right now because I can only find tutorials for really basic stuff

[silk sleet]

if ur real bootleg u can grab a good anim system from marketplace and just yoink the bits you need lmao

[dusk nebula]

Like, I need to make or remap one (1) animation for something before progressing and can't find a reasonably good tutorial

[silk sleet]

look into 'retargeting'

[dusk nebula]

Is there a good video guide you know of? The official documentation is weirdly hard to follow for this

[silk sleet]

you'd likely attach individual static meshes to bones on the character mesh

[drowsy snow]

If multiple skelmeshes share the same skeleton, no need for (hard) retargetting.

Best bet would be either a single anim BP with a Copy Pose From Mesh node in the anim graph, or Set Master Pose Component in the character BP.

[silk sleet]

I don't know of any guides for retargeting. what are you trying to do exactly?

[autumn latch]

hello

[drowsy snow]

He's trying to make modular characters.

[autumn latch]

i can't set this veriable in bp

what should i do for this?

[modest trench]

Get the reference to that component first?

[silk sleet]

also I like how we clarify one (1) and then immediately say something lmao

[drowsy snow]

I don't think this variable in particular is BP read write.

[silk sleet]

you'd likely have to expose it to BP yourself. which isn't that hard if you got cpp chops
https://forums.unrealengine.com/t/set-angular-rotation-offset-through-bp/113762/5

[modest trench]

I'm surprised it's not directly exposed

My bad

[silk sleet]

there's a bp workaround in that thread too

but its gross

[silk sleet]

yeah should be lol

[drowsy snow]

Worth mentioning that modifying engine code can't be done with vanilla launcher build, at all. The source code files on vanilla launcher build are mainly for project level C++ classes to compile.

[autumn latch]

i am don't know cpp :'(

there is a have plugin?

[silk sleet]

you can modify w a vanilla launcher? you just build your own engine from source

and thus gotta run through all the github hoops

unless that's changed, idk

also you don't need to modify the engine to do this

[drowsy snow]

No, it's not changed, per UE licence.

[silk sleet]

in any case, I've definitely built my own engine and have never messed w my launcher. dunno

I also have shit memory though

[dusk nebula]

So I can just play an animation with anything if the bones match? I keep seeing the yellow messages about the first person arms playing a mistargeted animation, but I assume it's not really an issue

[silk sleet]

the fix involves knowing cpp. dunno about any plugin but I doubt there's one
I'd try that BP solution at the bottom of the thread I linked

[dusk nebula]

To be honest I just need to find a beginner animation tutorial because I've never gone through it from the beginning. Most lazy guides give you the assets and then tell you exactly how to connect them

[silk sleet]

not a bad idea. also go study a good working system

esp bc it's hard to ask the qs before you know the terms yadig

[dusk nebula]

Yeah, that's also a good idea. I just need to get a good idea of the animation workflow

I have something that's reasonably good and playable, I think, but there are no animations aside from character movement lol

[silk sleet]

have fun! if it makes you feel better, I'm shit at animations and I've been doing it in UE for years

[dusk nebula]

Yeah, I don't expect to be good at it. I just want to be able to make any at all haha

[drowsy snow]

Same, I've been using my custom 4.27
Though it's mainly for anime shading model, and this super epic lens flare that I kept drooling over

when it's going to be the black friday sale on the unreal engine marketplace?

[drowsy snow]

BTW if you want to get this le epic lens flare, check out this tut
https://www.froyok.fr/blog/2021-09-ue4-custom-lens-flare/
It's based on Batman Arkham Knight's lens flare system, which in turn is based on John Chapman's lens flare system.
It requires quite a bit of C++ and USF shader coding, and engine modification is necessary to probe Unreal's RDG (so this can't be done in vanilla launcher build).

[silk sleet]

you're saying it works but its against TOS or somethin?

also siiiick

[drowsy snow]

WDYM against TOS?

[silk sleet]

thought you said something like 'per the ue license'

[drowsy snow]

Well, per UE licence, is that the source code is only available for any licencees, not open source in any sense. Licencees can modify it to suit their needs, however.

I'm making a train track for a cinematic and I made the track with a spline. How can i do cull distance for spline.

When I turn the lights on it gets 10fps.

[drowsy snow]

Is your cinematic has to show the train ride from outside, from start to finish, completely uninterrupted?

Yeah, if the shots are not going to be on the front side/outside, uninterrupted (a la Norwegian Slow TV train rides), then the tunnels can be faked with scrolling tunnel meshes moving back and teleporting forth

Besides, faking the tunnel could help eliminate potential camera motion blur and interpolation issues

[grave pollen]

' Spline Component Duration Specifies the duration of the spline in seconds'

I dont understand - what does this mean and why is the default 1 second?

        const TCHAR* DllName = TEXT("nvEncodeAPI64.dll");
...
                NVENCAPIPROC NvEncodeAPICreateInstanceFunc = (NVENCAPIPROC)(FPlatformProcess::GetDllExport(DllHandle, TEXT("NvEncodeAPICreateInstance")));

Seems the "nvEncodeAPI64.dll.NvEncodeAPICreateInstance" Error 15 means : ( looking at _NVENCSTATUS in nvEncodeAPI.h):

     * This indicates that an invalid struct version was used by the client.
     */
    NV_ENC_ERR_INVALID_VERSION,

It looks like this is enum with value 15.
So it probably has something to do the the version of the NV sdk vs what is installed, I guess? \0/ something changed there at first glance.
The version is:

In my case 2 is passed to this macro, to build up the version

#define NV_ENCODE_API_FUNCTION_LIST_VER NVENCAPI_STRUCT_VERSION(2)

...
#define NVENCAPI_MAJOR_VERSION 10
#define NVENCAPI_MINOR_VERSION 0
#define NVENCAPI_VERSION (NVENCAPI_MAJOR_VERSION | (NVENCAPI_MINOR_VERSION << 24))
#define NVENCAPI_STRUCT_VERSION(ver) ((uint32_t)NVENCAPI_VERSION | ((ver)<<16) | (0x7 << 28))

.. not 100% sure how this helps you, but it shows the error, and not just some random number, and I mean the numbers dont really mean much anyway, but there is a version issue with what the engine is sending to the video codec. So something changed there I imagine.

Just googling NV_ENC_ERR_INVALID_VERSION leads me to solutions where people have updated the NV drivers using the Geforce Experience (rather than Windows drivers for example ).

Hi, I want to create a camera blueprint with my own component class inherited from UCameraComponent. But when I create a ACameraActor, I cannot replace the default camera component by my own. What's the correct workaround here? Should I just create a simple class inheriting from AActor, and put my UCameraComponent in it? I tried that but it doesn't behave as the default ACameraActor, so I'm wondering if it's the correct way to do this.
My goal is to only lock the head orientation to the HMD and not the position, because "Lock to HMD" locks both, and for some reason it moves the camera under the ground.

[sharp oasis]

Does some one know how to fix it_

[drowsy snow]

Download the source code files via your UE5's installation settings in the launcher.

It has to have the source code files for project level C++ stuff to compile.

[sharp oasis]

it was already selected

[tender pecan]

Problem is ACameraActor defines the CameraComponent as private.

    /** The camera component for this camera */
    UPROPERTY(Category = CameraActor, VisibleAnywhere, BlueprintReadOnly, meta = (AllowPrivateAccess = "true"))
    class UCameraComponent* CameraComponent;

So yeah, probably going to need to roll your own CameraActor, you have access to the source so you can see what they do there, and change what you want.
In all honesty though ACameraActor.cpp does not really do much , so just roll your own, it has no tick functionality and just registers some stuff in begin play and supports serialization.

[plain ferry]

Yeah it seems feasible to redo the same when looking at the CameraActor code. But I'm a bit worried when I inspect all the CameraActor::GetCameraComponent() calls. Because if I inherit from CameraActor directly, I won't be able to return my own component since the field is private and GetCameraComponent() is not virtual, but if I inherit from Actor directly, all the places that use CameraActor (and who call CameraActor::GetCameraComponent()) won't do anything since it won't be a CameraActor anymore.

[tender pecan]

Def dont inherit from it. that wont work. 🙂 As i said above.

But yeah, your 2nd point is def valid. I mean do it, and see what does not work, and take it from there

Alternative is get the source vs binary, and just you know, change it yerself. 😆

Then no need for custom anything

[plain ferry]

Ok, thank you! Will try that then

[tender pecan]

👍

Also, a lot, and I mean a LOT of those references ( to GetCameraComponent() ) are for Editor components, so you may be just thinking because you see it everywhere does not mean it gets used in game always.
The Camera that the player is currently using is king (that would be bound to the player and is the active viewport) . And that has been proven to be extended without any engine mod required. 🙂

Unless you want to modify the editor camera, then sure. aaaaal rightyyy then

[plain ferry]

ok, that sounds good 🙂 giving it a shot now

Is generated mesh at runtime necessarily cheaper than a normal spawn static mesh instance (foliage tool)?

[tender pecan]

A mesh will be cheaper than another mesh, if it has less vertices, uses less materials, uses dynamic instancing or their material uses less instructions and textures.
the generation itself has no impact when comparing performance. other implications such as memory and spawn time come into play when attempting to auto generate entire forrests with lush vegetation from nothing

[drowsy snow]

Also, to cause as less interruption as possible, procedural meshes has to be generated within initial loading, as to prevent huge stall from the CPU work.

That's why small size demoscene prods (realtime 3D presentation in 64 KB or less) often had long load times and took up a lot of memory real estate after fully loaded.

[rancid jay]

What do people do, to swap item inventory in item slots? Swap array's index?

[neon bough]

bubbleswap?

[rancid jay]

I am not smart. So, idk what is regular old swap. Would like to hear about it

[neon bough]

or wait, i might have used the wrong term

we call it "triangle swap" in my native language

not sure if thats a valid programmer term

[rancid jay]

Sorry, what are the 3 sets actually? 3 sets of different variable?

Um, to be clear. I am trying to solve the one that is like this. Swapping item A at slot 1 with item B at slot 5.

[neon bough]

is it maybe called "three-way exchange"?

[rancid jay]

So, after i store in an array, i store the items into a new "Set" variable, right?

I am definitely not smart

Thanks a lot, i definitely need BP first since i am way too dumb to figure this "simple" swap.

Appreciate it.

Gonna spend time on it

[full lodge]

What it means? 64 bin? It means that takes 16 textures with 4 channels each?

[drowsy snow]

A wild typo appears? No, it can't be 😱

[full lodge]

at the beginning, I thought, that it makes a 64 bit histogram

what they does inside shader

okay good

so it is divided into 64 intervals

cool thanks

laggy brain today, foggy day in Poland

thanks @plush yew @drowsy snow

[plush yew]

how can I import this flying paper animation into unreal from blender? it imports each paper page seperately and there's no animation like i made it in blender

[drowsy snow]

Either skeletal mesh + morph target trickeries, particle system trickeries, or alembic data.

[plush yew]

mhm ok

i can't make it like complete one detail object and just import it like that?

[drowsy snow]

If you value absolute accuracy on the paper count, then those fakery method I mentioned above.

[plush yew]

i have to play around with those in blender?

thought making animation was hard, but now importing lol

thx

[drowsy snow]

Yeah, and if you don't mind the lack of realtime physics sim, then preanimating it and exporting as alembic or skelmesh + morph target is the way to go.

What DCC tool you're using?

Macarena.

By DCC tool, I mean software like Blender, Maya, ZBrush, 3ds Max, Metasequoia, etc.

[plush yew]

ok

[drowsy snow]

Whoops, sorry for missing that.

[patent cobalt]

DCC = Digital Content Creation

[drowsy snow]

Anyway, do you have your unit scale set to 0.01?

This should be your new normal in Blender.

And of course scaling things up to 100 times, if necessary.

In orthographic views, you should see the grid representing the length unit.

[patent cobalt]

Check the scale of the root bone of your skeleton once it is in Unreal. If it is not 1,1,1 but 100,100,100 you have scaling issues

[drowsy snow]

I don't think so. AFAIK anims scale up fine, given if the keys are LocRot

Also make sure to apply the new transform beforehand.

[hidden dew]

Cool... tracked down an annoying bug to a rounding error in a Material.
Except it didn't fix the bug and was just some unrelated other bug I've inadvertently fixed.
That's... nice.

[stable path]

@plush yew You have to animate then when they're at scale 1

If you animate at some other scale and then apply transform, it's going to cause such issues

[full lodge]

what that function does? https://github.com/EpicGames/UnrealEngine/blob/9e0f5f2a419a75b83392c44bf75462366ca8c1e2/Engine/Shaders/Private/PostProcessHistogramCommon.ush#L67
Loads texture and then at 0 index: R channel, 1 index G channel and so forth?
float4 HistogramColor = HistogramTexture.Load(int3(Texel, 0, 0)); I mean about this line

[drowsy snow]

Maybe #cpp know something.

[full lodge]

ok

[stable path]

@plush yew In Blender,
In edit mode,
Make sure all your bones are at unit scale
Then in Object mode,
Make sure the whole skeleton object is also at unit scale
Then just to make sure, apply transform

[drowsy snow]

It's going to be weird animating with unapplied transform 😅

[stable path]

Then export your mesh and while importing in Unreal, use 0.01 as scale

That's what worked for me

No, do all the animations at 1

It's good to have a scale of 1, makes it easier to work with

[drowsy snow]

I keep holding back from posting about the new normal in this regard. Wasn't even sure if that's going to worth a pin or not.

[plush yew]

when I import as alembic it's just empty file

[stable path]

@plush yew in the Import dialog in Unreal, use scale of 0.01

[drowsy snow]

Send to Unreal?

I hate the collection workflow tbh

No, you make the object in Blender 100 times larger.

The transform won't be applied that way.
(and the apply transform checkmark is somehow broken)

[neon bough]

you should press CTRL + A and apply scale (in blender)

[drowsy snow]

Though with Send To Unreal, the collections have to be specific.
Which is I despise so much because it break my modular character workflows.

[neon bough]

just because blender isn't foolproof doesn't make it a bad software

[drowsy snow]

For a FOSS, I'd say it held the high bar for digital content creation. And it's more accessible than Autodesk's shits.

And hope for the best 😛

[neon bough]

wait

you meant unit 0.01 and not scale?

[drowsy snow]

Fingers crossed, lass.

[neon bough]

ok, i lost you there, you may still have to (scale by 100) and apply scale

while the scale by 100 depends on your scene

anyways, your object should always have a final scale of 1,1,1 when you export

if its to small with 1,1,1 scale, scale it up to 100 and apply scale again, if it's to large scale it down to 0.01 and apply scale

me too

ok let me try to rephrase it

when you start a new project you set your scene units to 0.01
the default cube is then 1x1cm instead of 1x1m

in blender and fbx export

if you want it back to 1x1m you have to scale the cube by 100 up and then hit CTRL + A => scale (to apply the scale)

this has to be 1.0 before you export (which you get by using the CTRL + A => scale shortcut)

on the other hand, i had your issue only with rigs

when i import an fbx from unreal to blender, and work on that data and bring it back to unreal it always had correct size

[drowsy snow]

I think it's time for me to share my "new normal" for Blender to Unreal, with 0.01 unit scaling, and (almost) all clipping distances adjusted to it. It has been my "startup file" for a long time. More fool proof (IMO), while still allowing your own set of collection.

(Blender 2.93 or newer, no plugins required)

[neon bough]

does it have an anime figure instead of the default cube?

you cant compare blender to gimp

[drowsy snow]

Probably

[neon bough]

i agree with you on gimp

[drowsy snow]

Not even close. GIMP is far less intuitive

[neon bough]

well, blender, too

gimp really misses a bunch of features, specially when working with layers

or i'm just too stupid to figure out

[drowsy snow]

As a third world bloke, I'd still take usable free software, over resorting to piracy of industry standard software.

[stable path]

@plush yew Try using a scale of 1 instead of 0.01

[neon bough]

and same for the rig then^

[stable path]

👍 Same

[neon bough]

usually you screwed up your rig most likely

as your animations and skeleton within unreal probably have a bonescale of 100 somewhere

most likely the root bone

[neon bough]

you are from the states or eu?

that's the majority of 3rd world countries

[drowsy snow]

Not even from the West.

[neon bough]

just covered in flat screens

however... seen people work with maya and i couldn't see much that i wouldn't be able to do in blender in less time

only the maya retopo thing where you create faces by clicking on the underlying mesh seems neat, not sure if something similar in blender exists

[gaunt abyss]

Because that's how every normal human being should think?

There is no excuse for piracy

I'll remind you that encouraging piracy is heavily against our #rules

[rotund scroll]

does borrowing someone else's netflix account constitute piracy? 🤔

[neon bough]

read their terms of use

that will answer it

[plush yew]

can you move cinematic camera more softly? like with keys mimicking mouse movement

in real time

[rotund scroll]

you can do anything you want

[plush yew]

i know

lol

[rotund scroll]

why did you ask if you knew lol

[plush yew]

i mean instead of creating checkpoints at sequencer and changing camera position, rotation every few seconds

how can you control it with keys

[rotund scroll]

well that's an entirely different question

if you're using blueprint, then Input events

[plush yew]

using buttons instead of standart move, scale, rotate

[rotund scroll]

oh

you mean in editor?

[plush yew]

well

yeah

kind of

i just need a clip

[rotund scroll]

I believe there is an option called Pilot Actor in the right click drop down

[plush yew]

yeah im using it already

but how to use more advanced movements

[rotund scroll]

what kind of advanced movement do you need? I don't think you can expect the camera to have a backflip implemented by default

[plush yew]

like joystick

mouse

slowly rotating

you know what i mean

[rotund scroll]

I'm not sure that I do

[plush yew]

controling camera

without the shake

that mouse has

just steady movement

[rotund scroll]

like a dolly?

[plush yew]

yeah

like real camera

making it smooth

[rotund scroll]

I think there's something where you can set dolly spline points but tbh I haven't worked with cinematic cameras

try asking in #cinematics

[plush yew]

ok, thx

will figure it out somehow

i think it's this, when you move around it kind of smooths out camera and makes image steady

[zinc shore]

so i accedently created a return node and now it wont let me delete it no mater what i do whats going on

is this a bug?

looks like it is https://answers.unrealengine.com/questions/156732/collapse-to-function-creates-a-return-node-you-can.html

[dry birch]

What device profile will ue4 use if the device gpu is not in the list of the device profiles?

[glacial needle]

Hey guys, Why do I not have the option to install 4.27.1? The highest version it says for me is 4.27 chaos

[dry birch]

Coz i think if the device has a gpu that is not listed in the list of device profiles it will use a wrong device profile resulting in a massive issues

[tacit moon]

Anyone know if UE5 works well enough to do game dev on the new M1 Pro?

[neon bough]

no

apparently it runs in the emulation mode and therefor gpu performance is nuts as it can't use metal or however their renderengine is called

[rotund scroll]

ask in #cinematics they have epic people there with expertise

[plush yew]

yeah, waiting for answer there

[zinc shore]

it docent run nattily so you have to use Rosetta but it works pretty good ive been able to use it on a m1 mac book air just fine

once they add m1 editor support it will probably be much better

[shell thunder]

The base M1Pro GPU has 5tflops, thats about as much as a 980, add the emulation layer on top of that and I highly doubt it's going to be particularly smooth for deving and especially not at 4k

[zinc shore]

the only issue ive had is the sky looks like this

[neon bough]

xD

did you even add anything to the scene besides the sky?

[zinc shore]

while on linux it looks like this

[zinc shore]

yeah im just looking up

its just the default fps level

[chrome field]

Does anyone know how to create a custom random loop decorator?

[hollow cairn]

hello dudes

[tacit moon]

@zinc shore That makes me think I'll run into a lot of issues with the M1

If the default sky looks that bad, how am I going to do shader dev with everything looking wrong?

[hollow cairn]

I am using some animations from mixamo for climbing and one of the animations (climb down) has the character higher up than the others so when the character moves down, the animation makes him move up first

how do I fix?

this is idle

this is climbing up

and then this is climbing down

idk if you can tell but he is way higher up on that animation

[dry birch]

Help

What device profile will ue4 use if the device gpu is not in the list of the device profiles?
Coz i think if the device has a gpu that is not listed in the list of device profiles it will use a wrong device profile resulting in a massive issues

[vague marsh]

Hello guys, I’m learning Unreal and I have a doubt, anyone knows how to fix this noise when I press play?? Thank you 🙏🏼

[drowsy snow]

ngl this looked like anime sky

[patent cobalt]

@vague marshnever seen that, it reminds me of old VGA cables when you would pull is slightly and only some colors would go to the monitor. First make sure your graphic drivers are up to date.

I wonder if eventually the will add the possibility to drag a component onto an FName field and have it copy the name to it

[neon magnet]

Man I just don't understand these crashes. I updated my gpu drivers yesterday and so around 24 hours or so of rock solid, no crashes. And then just clicking on a value in the editor has caused this crash and apparently it's all to do with PhysX but I am not doing anything with PhysX at all.

true but it's just so frustrating sometimes. I wish there were more detailed errors like "this happened likely due to so and so reason" that I've noticed in some programs but it's exceedingly rare

[neon bough]

that's a weird way of handling crashs 😄

[neon magnet]

yea but it'd be informative, it gives a hint or direction to look at

[patent cobalt]

Which engine version is that?

[neon magnet]

right now it doesn't tell me anything, I can't figure out if it's a problem on my end, or a problem on a driver. If it's on my end, then unreal is the only one that crashes like this, so it can't be my hardware, etc.

[neon magnet]

4.27.1

[neon bough]

i'm pretty sure the goal of epic is to avoid crashs by any chance rather than explaining them

[neon magnet]

where did I say "something happened"? ???

I said "this happened" where "this" is just a template word for an error that in reality would be something specific

[neon bough]

well, it doesn't tell exactly what happend

only where it happened

[neon magnet]

exactly, if I go to that cpp file it's just a line saying cout << so and so endl;

[patent cobalt]

There isn't much that can go wrong here

I like the @todos

😄

[neon magnet]

granted this is probably the first time I've encountered a PhysX crash, the earlier ones were SlateUI or something

[neon bough]

the address is a bit weird 0xffffffffffffffff

ah, ok

and kernel32.dll is normal, too?

i'm not a windows user, just curious

[patent cobalt]

yes normal

memory access goes all the way back to the kernel

[neon bough]

yea, but didn't expect a foobar32.dll

i'm a windows DAU, to me it looks like a wrapper for 32bit binaries 😛

but apparently its not

if you say its normal

[patent cobalt]

@neon magnetlooks like a problem with locking/unlocking the physics scene. Are you doing something with the physics scene somewhere else?

Or playing with gravity somewhere?

[azure topaz]

does someone know whats the blueprint for fill bar?

[neon bough]

you mean progress bar in UMG?

[neon magnet]

that's the thing, I'm not touching physics at all. The most I did was how much my character can jump lol.

[azure topaz]

no, fill bar, like when the bar is at 0 ,so it start filling again from it self, UI

[patent cobalt]

@neon magnetand you changed that where? In the CMC?

[neon magnet]

in the firstpersoncharacter bp

just the velocity of jump

I don't even think that would call anything heavy physics related beyond a simple math compute of vector

my doors have a 'get' that get the physics angular velocity, but I never touched them in the past few days and as aforementioned, I never had this error before (that I can remember)

[neon bough]

does the crash even reproduce? or was it a onetime thing?

[azure topaz]

can someone tell me?

[silk furnace]

is this chat where i can ask for help?

[neon magnet]

nope, none of these crashes I can reproduce. They're all random. Often it's SlateUI. When I was playing around with volumetric clouds, it would crash often and it would complain about something unrelated (the stars plugin I am using). Since then hasn't crashed (once I stopped playing with clouds).

[neon bough]

i'm certainly sure that you want a progress bar, because that's what you described

[neon magnet]

@azure topaz do you mean a bar that reaches to the end then restarts?

[azure topaz]

then it is what i want, its just i dont know everything how is it ,
