[queen rivet]

I am having a issue where the AI is following the player but not attacking the player after spawn. When I put AI bp in map without spawning, the AI works perfectly well but after spawning AI is not attacking player. There are two halves in behavior tree where in first half AI is instructed to follow around the players and in second half, AI is instructed to attack. First half is working but second half is not working.

[still tulip]

Anyone know who wrote the UE documentation?

It's all over the place and short

Nevermind found my answer on /r/unrealengine from 3 years ago

[low breach]

Hello guys! I'm looking for some help with putting 2 textures on one material!

Could anyone here help? I will post a picture and explain further if someone replies 🙂

[rugged dawn]

What exactly do you mean? You want to blend between the two in an unreal material?

[low breach]

Check #materials dude

[rugged dawn]

btw, if there is any other suggestions on how I could get rid of this weirdly baked spot? xP

[real heath]

This is baked lighting? Are your lightmap uvs properly created with enough spacing? Does it improve if you increase the lightmap resolution for that mesh?

[rugged dawn]

The table is a megascans asset, uv resolution already set to 2048 and UV map looks fine. asset also looks fine when opening the mesh in UE

[real heath]

The lightmap usually uses a second uv set

If it doesn't have that it might be auto generating one. If the lightmap res is already set to 2048, what is your lightmap quality set to? Maybe bump that up a level

[rugged dawn]

Generate UVs is turned off so I for sure only have one lightmap. What do you mean with lightmap quality? Cant seem to find that setting

[real heath]

It's in the build menu

You can build as preview, low, medium, high and production

[rugged dawn]

Oh, thats set to production already

but in all quality levels the spot is showing

I've been editing lights, the meshes and other settings for 2 days with no positive result :/

[real heath]

You placed a flat plane above the table to see if it catches that shadow?

[rugged dawn]

No, I'll give it a try

[real heath]

Yeah I'd just try stuff like that to narrow down if it's only catching in certain meshes, if the plane does catch it, maybe keep moving it up and up till it reveals what it's coming off?

[oak patio]

Please don't crosspost

[woven perch]

Is there an easy was to see the actual actor instanced name rather than the display name during runtime in editor?

[rugged dawn]

So it seems to dissapear as I move the plane up but there is no lights near, except from the candles

[real heath]

Does it only happen with baked shadows? If you kick it to realtime only lighting does it go away? Have you viewed your scenes global distance field?

[rugged dawn]

I think it does, this is the mesh distance field. on the right the global one

not sure how the global one is supposed to look?

[dreamy wasp]

You will spend the 1 month coding, and getting something to work, then you will spend 6 months getting it on steam.
You need $100 deposit per game on steam, so don't think it's free, and games only sell if they are good.
Remember there are 300+ titles released on steam each week.
Go to CGtrader and search free assets.
Do not spend a lot of time on the assets, since you only have a month to code.
gameplay is #1, not a cool mesh or FX

[oak yew]

Does anyone know a better way to get true random in UE4? For example "GetRandomPointInNavigableRadius" is not random and will always spit out the same pattern, I'm looking for a way to get something more random.

[thin tendon]

When telling a computer to get random it can often be very mechanical and produce the same results repeatedly. It comes down to how the get random was programmed. What you can do is add a second stage of randomness. So for example. Get random point in radius. Then - random amount on the x axis.

[oak yew]

@thin tendon Thanks that was a good idea, if I simulate too quickly it does pick the same ones, so I guess time is involved, but it's a lot more random than before. Maybe it uses all inputs as a seed. In UE5 it's a lot better and more random but I can't use UE5 😦

Damn now it's still returning the exact same coordinates, it's like UE is caching them or something..

Each block is me clicking "Play" in editor...

[real heath]

Not sure this exists, but it's what I'd do. Look for a node called "srand" or Set Random Seed or something, and then seed it with the current time (not game time, actual time)

[rugged dawn]

So, ive decided to switch to fully dynamic lighting but the mesh distance field is ignoring the inside mesh of my book. Any fixes? Thanks in advance

[oak yew]

Couldn't find a node like that, there is some for Streams, but requires an int.

Even this isn't random... 😩

[static viper]

what do you mean

[spice ruin]

https://xkcd.com/221/

xkcd: Random Number

RFC 1149.5 specifies 4 as the standard IEEE-vetted random number.

[oak yew]

This is the index printed, every 0.5s each time i click play

[spice ruin]

It's probably seed-based.

And it's using the same seed 😄

[oak yew]

Yeah, im trying to figure out how to get around that or change the seed.

[spice ruin]

Hi, have you met #cpp ?!

[static viper]

stop.

[oak yew]

Might have to go C++

[static viper]

i need to see more code and the contents of the array.

[oak yew]

It's an array of strings.

[static viper]

no thats not strings.

those are names.

so you have tried random integer?

do random int in range

type in 0 and a length

and then use the get node instead.

[spice ruin]

length - 1 surely

[oak yew]

int does same.

[static viper]

impossible

it isnt seed driven

there is an extra node for seed random

odd

[spice ruin]

https://docs.unrealengine.com/5.1/en-US/random-streams-in-unreal-engine/

You can init your own random stream

[spice ruin]

I did this the other day and just converted the current datetime tick value to uint32.

[oak yew]

Modifying the Initial Seed
To set the Initial Seed property directly on the variable

this actually doesn't work, but you can set it with a BP after.

but then i have a hard coded Seed

so it doesn't become random? right?

[spice ruin]

Within a Blueprint graph, you can also set the Initial Seed to a specific value or a new random value.

[oak yew]

if i set seed to a random int... then the initial random int has a fixed seed.

[static viper]

holy f that is sad

this used to work just fine in the past

[spice ruin]

If the random value is based on a set seed, is it truly random?!

It'll just generate the same random seed every time!

[oak yew]

Yeah

[thin tendon]

What if you create a function or macro for generating your own random numbers? Just use multiple layers of randomness to increase the chances of a different result.

[oak yew]

@thin tendon if i do that in BP i suspect it'll always be the same.

I think i might have to go to C++ or check if it's a specific issue in 4.27.2

[static viper]

this is really really strange

this should absolutly not be like this

there is something really really wrong

and i used 4.27 extensively

[thin tendon]

I agree you expect to see some repetition but not like that.

[spice ruin]

This is why I like the datetime system. It's guaranteed to be a new seed each time it's set.

Unless you have hyper speed

[static viper]

yee thats how the computer usually does it

he could in theory code such a thing

you can get datetime in unreal

[oak yew]

i tried a brand new blank project and it happens

datetime sounds interesting, there a BP node?

[static viper]

try ue5 too

[static viper]

yee

its just a node called get date

i think

[spice ruin]

You'd need to convert it to an int

[static viper]

thats easy

its already in int

you just need to combine it

[spice ruin]

There's a "get ticks" method in c++ that returns an int64. Take the bottom half of that and you've got your uint32 for the seed.

[static viper]

thts a smart idea too

delta time passed

[spice ruin]

How that translates to bp, I don't know.

Delta time passed will always be the same on the first tick.

[static viper]

then wait a frame

[spice ruin]

So now we're adding timers ?! 🙂

What's wrong with using real time?

[oak yew]

I think we might have success 😮

the 1st big number is millisecond

passed into Set Random Stream Seed

[spice ruin]

Millisecond is alright.

Limits you to 1000 possible seeds, though.

[oak yew]

yeah i can add more was a test, i am thinking how i can hack this into GetRandomPointInNavigableRadius

maybe i can offset the origin slightly, unless that node takes the current RandomSeed

[thin tendon]

maybe you could. get random 0-360. Line trace from player to the distance you want at that angle. And use that point to generate the random point in radius kind of thing.

[oak yew]

That could be a good idea, do some line trace, though my map is quite large and I'll need this for random NPCs walking about so im not sure how to know if it's within the navmesh

lololol i mean it works but it's a bit nuts, i'd need to set a base radius per map which is np

[oak yew]

@static viper @spice ruin @thin tendon Thank you guys for helping me, super appreciated! 🥳

[dreamy wasp]

A lot of people use get gametime, to get the random number.
I have used get random int in range, but many time it will put out 5 5 5 5 5 16 2 82 5 5 5 5. It just seems to get hooked on
one number, even though you are asking for 0-100.
What I do is have a second variable that remembers that last number.
So if it selects 5, it checks it against the last number selected. Bool If Rand=OldRand then pipe it back into the random int, if it does not then set OldRand=Rand, and proceed with your code.

[spice ruin]

You could use something that gives every number in the range before repeating. I have no idea what they're called, but an example is the mersenne twister.

[dreamy wasp]

If you really want things to have a lot of variety....
You can have an array. Select random int in range 0-(get array length), and when something is selected you can delete it from the array, making the array 1 size smaller. You can let the arry burn out, or you can restart the array after a certain number of choices. this would make it so you have a different outcome, and no repeats.

[dreamy wasp]

🤨

Reading my mind?

[spice ruin]

I'm just that good.

I'm not a wizard for nothing.

[oak yew]

Didn't know about GameTime, might feed that in as well as another RNG seed

I've managed to get variation now with the seed and time, and it works with GetRandomReachablePoint which is a lot better for bigger maps (in my exp)

[hybrid light]

Hello, I'd like to ask for your help, please. I'm just getting my hands on UE4. It's silly, but I'd love to know how to change a character's mesh without breaking the rig and animations already present. For example, I went through the "Reimport base mesh > Reimport content > Geometry" on my character's skeleton mesh. However, I only have half of my animations that work well with the new mesh. I thank the person who could help me.

[bleak locust]

exporting my project soon. anything i should know before i export?

[patent tusk]

Hello im using a zombie animation pack with my AI zombie enemies. I have a Blend space 1D with a simple Idle, walk, Run animations, but i dont know why the walk animation does a rare movement and the character slides to the sides, I dont know how to fix it, I try to enable or disable root motion but nothing happen, can someone help me pls?
I want the character to not move the root with the animation, and I disable the root motion and nothing happens, I dont know if its the animation or the model.

[west merlin]

Looks like the animation only has a forwards and not an angled forward animation sort of.

Anyone have any ideas for physics settings to make vehicles that function like PUBG? Players can't move the vehicles by walking in to them, but the vehicle punts players when it hits them without messing with the trajectory of the vehicle

[frozen grail]

you may want to also enable "Force Root Lock" while you disable "EnableRootMotion". hope this helps! video example:

[wet berry]

Has anyone else seen a bug in 4.27 where the BP context menu stops rendering?

It's still there, I can see it if my mouse is hovering over the text box

But if my mouse is anywhere else it doesn't render

Restarting editor resolves, but it's annoying to have to do that like once an hour

or once every 10 minutes

[fickle maple]

When I turn on MSAA, my level turns black with some weird ghosting, does anybody know why?

[digital anchor]

are you using the forward renderer?

MSAA is not compatible with deferred

[fickle maple]

yes, i'm using forward renderer, my project is in VR

[peak oxide]

Is there a Console Command to open the content browser?

[true ridge]

Is there a way to forcibly delete an end user's Saved/Config files in their AppData folder? Basically treat the game like a fresh install even if there are older config files available.

[patent tusk]

Yeah, do you mean I need a normal Blend Space, not a 1D?

[patent tusk]

I tried to disable the root motion in the walk animation and force root lock and do the same thing, It could be because its a character controlled by IA?

[rain badger]

Could/Should I put my casts in the construction script?

[spice ruin]

Depends on the cast. Casts are free unless they load a class that isn't already loaded.

[pure slate]

To me it looks like the movement speed is a little too fast for the pacing of the animation, and the "sliding sideways slightly" is a forward walk anim playing while the pawn is rotating to face the player.

[spice ruin]

If what you're casting to is already in your map, is your game mode or player controller or whatever, you're fine.

[rain badger]

So the Game Instance would be fine too, right?

[spice ruin]

Correct

[patent tusk]

I think you are right with the speed, but the Zombie is moving to a patrol point all the time its not trying to face the player with the code i got right now

[rugged dawn]

Hi guys, Im rendering a sequence where the camera is pretty much just zooming in and for some reason at a certain frame the camera jitters back and continues zooming from there with some weird focal length and focus adjustments. Anyone can help? I dont have a keyframe at exactly this frame

I have keyframes for aperature and focal length, however disabling those also doesnt seem to do the trick

and when scrolling over my sequence, this glitch doesnt show in the viewport

[patent tusk]

Someone can help a good way use root motion to an IA character? Using a Blend spaces with turn and forward left and right animation?

[dreamy wasp]

Some of those animations are not synced. Meaning they don't line up exactly.
When the Blend 2d or 3d blends the animations it does not know exactly what you want. It just blends. If the feet are not timed the same it will cause floating. Like if the walk is a 24 frame walk cycle, and the run is a 15 frame run cycle, they will not match, and will look strange if blended slowly.

no animations can exactly match the floor. People sometimes lock the feet on the ground, with a script, to make them stick better. but that is more complex than I can do.

[dreamy wasp]

Casting has a cost, so don't do it a lot. if you have a ball that casts to the game instance, it's best not to have it also cast to the box, if you can help it. If the Box is already putting info into the game instanc, just have the ball look there. Too many cast are bad. It's worse than tick.
Get a variable and use the veiable instead of casting each time you want something. Cast once.

[patent tusk]

But if i delete the run animation form the blend, it looks the same, do you know what I mean?

[patent tusk]

This is my blend only Idle and walk and it does this strange move

[blissful steeple]

what is the command to keep nearby actors and texture loaded when they are behind me ?

when i look left or right, there are always npcs loading, or textures like rocks, ground etc

[glacial wyvern]

The same setup works in a paper character blueprint class but not for a regualr actor

[neon wedge]

Any specifics?

[spice ruin]

Any assets you can pretty much use as you like.

Stuff in Editor or Developer directories are a no-go.

That's just what the EULA says.

You can't distribute them.

Or anything that uses them.

I have just opened up the robo recall mod tools in a unreal engine 4.16 project and a lot of the static mesh actors appear to be read only. I am trying to break the project apart to learn how it was done. Does anyone know how to get them out of this read only state so i can open the 3d meshes and their materials ?

I have tried

1. Right clicking on a mesh in the world outliner (no options to change state)
2. Opened the folder containing the .uaasset to see if i need to user windows explorer to change read only state
3. Right click on the asset in the viewport and convert actors to static mesh (this helps as i can now open up the mesh but i still cannot get into the material instances inside the mesh)
4. Rich click on the mesh in the content browser and choose edit (does nothing)

the mod kit is downloaded from the epic games store

Very cool if no one has checked it out ( for VR ) although I am seeing a lot of the blueprint logic is outdated. Still useful though in a lot of ways.

Can anyone recommend a publisher, they liked working with?
currently, I am getting 'offers' from these 'pay-per-click' type places that offer X amount of views, live streams, influencers, reviews, etc, for XXX amount of cash. Not interested in throwing money into the void.

[autumn flame]

I imagine if your game grabs enough initial attention or the right attention proper publishers will contact you about deals
Keep in mind they will want a revenue share starting minimum 20% and max 40-50% depending on relationship

We got such deals and they contacted us, so

[dreamy wasp]

that sounds a little backwards.
Like.. to get an agent, you already need to be in a movie.

One of the main jobs of a publisher is to promote and advertise your game. That's why they get a percentage.

[thin tendon]

A couple of planes would work. Or even just go into blender and make a custom face the size and shape you want.

[autumn flame]

There's so many games that the market is saturated, gotta stand out

[dreamy wasp]

Take them into the scene and place them where you want.
If you want them as a unit, you can stack them in the level, or you can create a blueprint with all the stuff in it...
or.. you can place them in the level, then select them all , and right click and Merge Mesh.
This will make them all one mesh, and you can select if you want the materials merged, or kept seporate.
but then you cant just move a pillow somewhere else. its all one mesh, then.

[thin tendon]

You could also put them into blender and combine them into one mesh then import that newly created single mesh

I tried actually editing that .cs file but it said it was read only, and surely D3D11RHI is irrelevant for linux as it refers to windows only. For reference, my windows packaged version comes out completely fine with no errors! Any one able to help?

[hidden dew]

Needs a tonne of optimisation but shows promise.
About 1 million grass instances, each able to move and rotate independently, to follow the shape-changing surface they're on.
HISM for the instances. All translations and rotations done in material. Data fed to the material via texture, updated on the render thread.
Bit proud since I hadn't heard of ISMs, or render thread stuff, and didn't know how to do material transformation when I began trying. 😄

[thin tendon]

There isn't any way of knowing in advance unless stated by the seller. If you learn a little blender, then it won't matter because you can just change things to how you want them.

by the way, crossposting aint allowed, it makes the conversations confusing when its continuing everywhere.

[azure shore]

and this is why people get drowned out more than they already would

[steady tree]

im kinda confused - any Idea on why are the shadows missing when I open the level via open level function ( stationary directional light ) on moveable meshes/sprites but not if I just open the level

its the same in a packaged build - if the map is loaded on default = shadows, if loaded per ,,open level,, shadows missing

[steady tree]

works with a stationary spotlight - but not with stationary directional light ( Huh? )

[dark axle]

Yes

[steady tree]

okay that didnt fixed it either

[tall osprey]

hey anyone know how to fix my issue, so I'm trying to get the player to always face the enemy. I've tried it in the player blueprint, level blueprint both get the same outcome, When I do it in reverse the enemy rotates to follow me but when I do it for the character to face enemy the player doesnt rotate towards the enemy only the camera does

https://www.loom.com/share/5fd1f6767d49416da4415c8a5292dac3

[dreamy wasp]

You may be overriding the code, with your Axis Inputs.

Check how your character is rotating during normal play. this may be affecting your 'forced' rotation toward the Enemy.

[thin tendon]

Try getting your player character casting it to your "Character Blueprint" then setting the rotation.

[dark axle]

Hi guys, I have a problem and let me know on how to resolve this issue

[dreamy wasp]

Next time wear suntan lotion.

[dark axle]

Hahahaha

[dreamy wasp]

also your head is missing. Might want to bring that along.

but if you are talking about why your thong is on your thighs, then you need to recheck your mesh UVs.
Looks like it's not map properly. I'd suggest taking into blender, but if you bought that model, it should already be properly mapped.

[dark axle]

Actually I'm talking about why my character is loading this instead of the loaded one

[dreamy wasp]

Not sure what the loaded one is. Many time its just forgetting to assign the correct model.
Recheck. I had issue like this, and it always turned up to be something stupid

[dark axle]

Got it

thanks

QUESTION: Animation Budget Allocator <---------------- Anyone every used this?
The documentation is lacking, and I don't see much info, but it seems like something people would really want to use.

https://docs.unrealengine.com/5.1/en-US/animation-budget-allocator-in-unreal-engine/

Without modifying the engine, is there a known way to stop reflections from flickering?

I'm deep in development with 4.25.0 and really don't want to change engine versions because I don't want stuff to break.

[dense forge]

The easiest way is duplicate the material. Then in your new material to your base color add a multiply node and plug whatever you have coming and also a Color node by clicking 3 + left click.

[wide crag]

#ue5-general message

[peak hare]

In your original material, make the color input a variable, then you can create material instances based on this material and vary their colors as you wish.

[fair meteor]

If I share project files with a colleague, but he dosnt have the plugin installed to his engine, will this break things?

probably.

Hello, I'm having trouble to solve what seems trivial problem. SO basically is the mechanic of the RTS game where input mode is set to game and UI. I want the behavior where when I hovering over environment I have one type of cursor (simple cursor move to location) and when I hover over HUD UI elements i want different type of cursor. I know that I can make every HUD UI derived class from base widget class which would on hover notify the system. Just wondering if there is some cleaner solution with Get Hit Result Under Cursor for Objects or Get Hit Result Under Cursor for Channels!?

Hello, does unreal do multi-threaded draw call submission?
Say I have 500 Actors with multiple skeletal meshes each with 100 draw calls it's giving me 10 FPS.
Is there a way to submit draw calls parallelly on multiple threads? I noticed that there were only a few busy threadss (4).

why does the editor sometimes give this greyed out selection where when i press del nothing happens unless i reselect them and they are no longer greyed out???

[normal breach]

hey y'all, is there any way to move a component from one actor to another?
Alternatively, is there any way to make an actor skip the "UpdateComponentToWorld" for certain components? I already tried setting them as not visible and disabling any collision (they don't have any).

[distant crescent]

why do people still use ue4?

[wide crag]

stable.

[distant crescent]

ue5 is stableish

[normal breach]

migrating engines in large projects is a no-go

[distant crescent]

true

Well for some of us its better to finish a half done game in a stable engine then it is to migrate to a new one.

If your project is far enough along there is no reason to go to ue5

something strainge happening with my unreal engine, I have main menu where there are 2 buttons that creates new widget respective to there purpose.

hello sorry if you've heard this question like 1000 times but i wanted to ask a while ago i asked what was a good resource to learn ue4/5 and i got given learn.unreal.com and it was great but i never ended up using it because i got busy with other stuff and never did any game dev in the end well now it doesn't exist anymore or at least it just redirects me to forums but its all about ue5 and it really doesn't seem as organized can someone tell me what i can do or if the new site is still the best options what are some of the courses i should watch first so i can favourite them if thats still a thing?

[oak patio]

learn.unrealengine is now on the epic dev community

id go there

[digital lynx]

thats what i was talking about having only ue5 stuff and not being that organized anymore

so now i can't find all the old guides

[oak patio]

in fairness if you're starting out, theres no reason to use ue4

go for ue5

you arent in the middle of a large scale project so just go for ue5

[digital lynx]

i don't know it got more optimized since 5.1 but my goofy aah 1050ti can't run ue5

even disabling global lighting and the new features i still get a lot less performance then ue4

Anyone Familiar with using Voxel Landscapes?

I've got kind of a scenario and am clueless on how to go about debugging and fixing it.

tbh i'm also not even sure where to place the question, theres alot of channels on this disc lol

[tame marsh]

just post it

we generally don't bite here

[craggy shard]

When I'm in the editor the whole map looks great! but when I compile it anything made with the Voxel Plugin isn't loaded in. I'm using a Landscape as-well as a Voxel Landscape and trying to make a solid map instead of having to switch levels so to speak. Here's some screenshots for reference.

This is how its supposed to look Via ingame thru the editor

this is what it looks like ingame

The voxel landscape [cave] with the regular landscape on top I used a visibility mask to cut a hole into the landscape in order for the player to go through it when playing

the missing voxel landscape only happens when the game is compiled its the strangest thing

[red sinew]

https://gyazo.com/b3ad7d4bcced42f902de9149e3f13693 Uhhhh does anyone know why this is happening???

it's like it zooms in, and the camera goes crazy fast if i right click and move it

[digital anchor]

do you have a controller connected

happens when my R2 is stuck

[red sinew]

OH look at that that was the problem

tyty!

[craggy shard]

any suggestions?

[queen rivet]

I am working on creating a suicide bomb which explodes and destroys other players within certain radius. The problem is when the sphere radius collides with a wall or other objects then none of the actors are destroyed. However it works perfectly well when there is not a wall or other objects within radius. How do I make it destroy every players in radius even when there is a wall or other objects within spheretrace radius?

[copper bobcat]

You need to ask your question in the Voxel Plugin server.

[copper bobcat]

Use Multi Sphere Trace By Channel

You don't need the sphere trace, just use the Apply Radial Damage

Hello, using the branch Unreal 4.27-plus the Pico 4 SDK's plugins doesn't compile at all, what can I do?

[abstract lava]

can someone help me with something really simple and quick

[queen rivet]

sure

[abstract lava]

how can i move the chest back into place , when i try to move it it moves everything with it , it didnt do this before i changed the sprite

@queen rivet

[copper bobcat]

Other components are probably attached to the chest, which is why they follow the chest

[abstract lava]

im very noob .. so how can i move the chest back ? :/

[wide crag]

is this inside a blueprint? might want to check that the other parts aren't parented under the part you're moving, otherwise they'll inherit transforms

[abstract lava]

pretty sure the other parts are parented under that part , so how would i change that then ?

@wide crag

[wide crag]

you can drag the subcomponents to the same root as everything else, so

└── Root/
    └── Body/
        ├── Head
        └── Leg

becomes

└── Root/
    ├── Body
    ├── Head
    └── Leg

as an example, your context may vary

[abstract lava]

tysm @wide crag im going to try and figure this out lol if not ill be back .

[wide crag]

some standard rigging practices apply when it comes to part hierarchy. e.g. the "root" of a character is usually the chest, with the limbs and head parented to it. some setups have the legs as root instead, since it's closest to the ground.

it depends on what actions your character is likely to perform, and how each part moves relative to the others. the chest, being the most central component, moves the least

[abstract lava]

i feel so dumb 😐

[wide crag]

that's what learning is like, knowing that you're less dumb than yesterday helps

but the more you learn, the more you realize there is to learn

[abstract lava]

true ty . so i dont understand how to make it so i can move this piece still ..

[wide crag]

you can move it, just rearrange the other parts afterwards

see where your sprites' pivots are located. if you're using body as root then you shouldn't need to move the leg sprite independently, just animate the frames

[abstract lava]

i dont understand :/ is it because the animation if off center ?

[wide crag]

could be, yeah

that was it , thank you again . my last problem is i cannot seem to change the fps , i remember i found a place i changed it earlier but cannot remember how to get there . but this one doesnt change it @wide crag

Does anyone have any good literature about how plugin configuration works?

So I understand there is essentially a "stack" of configs (ignoring windows/android configs atm:

• Base*.ini (defined by engine)
• Default*.init (defined in project)
• *.ini (saved in save-game, not for editing)

Can anyone explain how this works for plugins? There are two things I want to do in my plugin:

1. Contribute custom settings (i.e., MyPlugin.ini)
2. Contribute base/engine/lightmass settings (i.e., DefaultGame.ini)

For (1) I'm fairly certain I can define a BaseMyPlugin.ini) and then let any project using my plugin override that using DefaultMyPlugin.ini, but I'm a bit more confused how (2) works.

If I define Plugins/MyPlugin/Config/DefaultGame.ini, how is that read in the config stack, if at all? The docs for configs has a hierarchy diagram, but it doesn't include plugins.

[abstract lava]

@proven mauve long shot but have you tried chatgpt

[abstract lava]

didnt work for my problem , thanks for not being helpful when suggesting chat gpt was a helpful suggestion and dude wanted to be rude just like you for no good reason lol . why so salty ?

[abstract lava]

it was a suggestion and its a lot mroe than word prediction lol!

[oak patio]

It isn't. Chatgpt is a word prediction engine. It doesn't know anything. It just predicts what words respond best.

[abstract lava]

dont comment if youre just going to be salty and not talk about unreal engine related things . it was a genuine suggestion and i even said it may be a long shot

[oak patio]

Based on interactions through the internet

[abstract lava]

it can code

[oak patio]

It can't code. It can guess that what syntax relates to the problem, based on similar interactions scraped from around the internet

[abstract lava]

it can do a lot more than predict words , and i recommend you watch a video on gpt 4

anyways this is for unreal engine conversations

[oak patio]

No matter how much you deny it, it is still a word prediction engine with no knowledge of it's own

[abstract lava]

im not denying word prediction lmao it does a lot mroe thanjust predict words my guy a simple google could tell you that . have a nice day

[plush yew]

It really doesn't. Have a nice day as well!

[oak patio]

Yes indeed have a nice day. But it's true

It's why it tells you to do silly things like connect getters to execution pins.

It doesn't know what a blueprint is, it doesn't know how they work, it just knows how other people have talked about and used them online, and it makes its best guess.

[abstract lava]

meh i dont care that youre both wrong , stay ignorant and salty . dont talk to me unless you want to help with my issue with unrealengine im having . . i was makign a genuine suggestion to someone cause there was no help on at the time . dont ask me why youre wrong go educate yourself or better yet ask chat gpt lol

🥴

I hope my question gets answered by anyone ie human or ChatGPT

come on, we dont have to debate over that

no apology needed, just ending needed which I think already got provided 🙂

[abstract lava]

i sent you something that may or may not help

[wide crag]

@abstract lava

could've just asked it, yknow

I work at a company that generates synthetic data for training AI models, I think you shouldn't immediately think about dissing a point like that without more understanding into how that particular technology works

[oak patio]

It's almost like language prediction, or word prediction!

I didn't see the point in arguing further when you Google got and it says "GPT is a language prediction model..."

[abstract lava]

now you say "its almost like " lol

[oak patio]

Just because it tells you what blueprints are doesn't mean it knows.

That would require sentience

[abstract lava]

yeah thats why you read more than a few sentences on google and dont make assumptions

[wide crag]

there's not really a need for sarcasm here, I think just getting to the point is better when trying to demonstrate something factual

[oak patio]

That was sarcasm. It is language prediction

[oak patio]

Very true. Wholly unnecessary

My apologies there

[wide crag]

in any case, it's important to understand what ChatGPT can and can't do, and when you should look at things with a more critical eye

[abstract lava]

funny cause this is for helping people and chat gpt helped someone you guys ignored asking for help to flame me cause i made a suggestion to help someone when there was no help online

[wide crag]

and the most important thing - humans made it. Humans are flawed. Don't expect AI to be that much more.

[oak patio]

Help which they didn't want, and you were snarky about when they said they want to talk to people about

[abstract lava]

not true were dming , snarky ? read your last comment again lmao

[oak patio]

Im not gonna give help if I don't know, but I am gonna raise an issue when people give dubious help.

Chatgpt ain't great with fairly unique problems.

[abstract lava]

youre just mdcause its gonna tale your job sad boi

[oak patio]

I'm really not. I recognize how to use a tool, and the weaknesses of said tool

[abstract lava]

then why be salty over me suggesting sonmone to use a tool , youre redundant

anyways im out . still need help btw

[oak patio]

The tool you offered in that circumstance is akin to bashing a nail in with a car battery.

It might work, probably not well. But there's certainly better ways of doing so

[abstract lava]

it works great , assumptions hints ass you dont know till you try it lmao you read a few sentences on google , read about gpt 4 or watch a video and youre gonna be really salty lolllll

[oak patio]

And I ain't salty at all.

All I said intially is that chatgpt wouldn't be too much help there, as it is inaccurate in highly specific scenarios. Spoken from experience.

Then this spiraled into how it isn't word prediction, when it quite literally is.

I really didn't want to restart this but here we are

[cedar pawn]

lets rename this channel to something like ChatGPT or not what do you people say ?

[oak patio]

I like it

I vote yes

[wide crag]

it seems like you have an issue with a missing Class definition in Java

I don't use Java so I don't think I can be much help beyond that

[wide crag]

the danger in learning from an unreliable source is that at some point you're going to pass down bad practices and cause problems for someone. Snowball effects.

[oak patio]

Fixed. The JDK folder must be Java Development Kit (64bit) 8 Update 151 to match a prerequisite of Gradle 5.4.1 used by UE4.25.

Not sure if this will be any use to you

Seems like a common issue thiugh

[wide crag]

Everyone I know who uses ChatGPT are capable enough to think critically and fix any errors it creates. You don't seem like such a person, unfortunately.

[cedar pawn]

thanks for mentioning the jdk , but I installed the jdk from the script that ships with unreal so I dont think that could be the cause

[oak patio]

I quite like chatgpt. It's great at explaining code. And really useful as a high level overview. In my experience getting it to debug or solve complex issues are beyond its scope ATM.

Excited for what it brings in the future

[oak patio]

Try it anyway, given it's a common issue for ue4 apparently, it may be worth a double check

[cedar pawn]

and yes I installed old gradle as well which unreal 4.27 uses, but still same error

[oak patio]

4.25 but in theory the error shouldn't be tied to the version

In practice though it's anyone's guess 😅

[cedar pawn]

makes sense

"To fix it, I finally ended up building a new keystore using the command line keytool (run as Administrator) using the Java keytool located in the Platforms -Android SDK Java directory setting.

It's directory-related, and macOS handles files slightly differently

Hi guys, need some advice as I can’t seem to find the right material to learn from 😪

I want to be able to create a 3d block based on the form of a 2d spline in play mode in which I can then move around and run different interactions with it.

Could anyone guide me to some tutorials or have experience with this ?

[wide crag]

sounds like you're trying to generate procedural meshes at runtime

[dusky schooner]

Yeah, creating a simple procedural zone ideally by drawing a line on the floor and then extruding up a certain height to create the 3d form of zone

[wide crag]

at a guess, you can get the hit position result of a linetrace at some time intervals, store in array and build a spline from that

I have a Particle System that runs to infinity. How can I make it appear smoothly and then disappear after 3 seconds? I played with the Lifetime parameter, but my Particle crashes after that. I don't understand, is it hard for you to help?

Do you know if there is a tutorial for something like this?

Awesome thanks mate. The extrusion part is gonna be the tricky bit for me I think

[fierce tulip]

required module > make sure it loops one time
then play with the lifetime. save occasionally.

[plush yew]

When I set Lifetime to 3, the particle disappears abruptly, and I want it to disappear smoothly.

[peak hare]

Hi guys, in the absence of a 'coneoverlapactors' node like the 'sphereoverlapcomponents' node, I just added a cone component to my actor with overlap enabled. However I will actually need to check the overlaps of this cone only occasionally. I have some questions about overlap:

1. Would I perform the equivalent of an overlap check by having tick disabled by default, then when I want to check overlaps I enable tick temporarily until i am sure there is at least one 'updateoverlaps' check, and perform a 'componentoverlapactors' check, then disable tick again after? If so, what's the overhead of having a non-ticking component with overlaps enabled?
2. Would I instead need to do the above rather by enabling/disabling the component (or both doing this and the tick method together?)? If so, would this be more or less efficient in terms of overhead than the above method?

[wide crag]

animate color/alpha over life to fade out?

[plush yew]

I have a particle Lifetime lasts for 3 seconds. In Color Over Life -> Alpha Over Life I set these parameters, but as the particle disappeared sharply and appeared sharply, and continues to do so.

[wide crag]

arguably one of the worse ways to view an animation curve

[plush yew]

What's the right way to make a particle appear and disappear smoothly?

[wide crag]

Your second point's In Val should be 1, and Out Val should be 0

https://docs.unrealengine.com/4.27/en-US/Basics/Distributions/ You want your Alpha value to ease out to 0 at the end of the lifetime

[plush yew]

Thank you. The particle started to disappear, but how do I make it start to come out smoothly?

[wide crag]

You might want a third point, in that case:
pt0 - In:0 Out:0
pt1 - In:<something like .1> Out:1
pt2 - In:1 Out:0

Fade from 0 alpha to 1, then back to 0.

[plush yew]

Now I have it displayed, but how do I make it disappear after 3 seconds? If I add two more dots, and set the parameters that I set for the smooth disappearance, then I break the particle at all

[plush yew]

I guess I should just create two partials for appearing and disappearing.
I did the same for the smooth appearance, but this partikl appears sharply, and continues to do so, and it ignores this curve

[wide crag]

your second point's In Val is too high. It should be between the points before and after it

[plush yew]

I did what you said, but as it appeared abruptly, it still appears.

QUESTION about Save files:
I noticed... I have a save with an array. The array is length 5.
It holds the guns that are unlocked. All bools.
I added 2 more guns, so the array is now 7, but it gives me errors when I save, because the earlier save only has length 5.

This is my problem: I can personally delete my save file under unreal/project/Saves/Save01
...but... People who download my game are not going to want all their stuff deleted whenever there is an update.
How do I do this for their save files to match the new array length?
Should I be using 'set array elem' with the [] Size to fit checked? Will that work on a save file?

[dreamy wasp]

Followup Question: If []Size To Fit works with an Array, will it work with an Struct Array?

[hidden dew]

Looking at Custom Primitive Data for materials, and considering it against Material Instance Dynamic with material parameters... :

The difference is that CPD has the advantage of storing data on the primitives themselves rather than with the Material Instance, which lowers the number of draw calls for similarly placed geometry in your Levels (such as walls, floors, or other duplicated geometry).

Can anyone explain how the MID could have more draw calls? I don't really get how it works.

For example, I have a MID with 2 texture parameters and 1 scalar parameter. All 3 are updated from C++.

Now I want to add a couple more scalars.
Should that scalar parameter I already have be a Custom Primitive? Should the new ones be? Does it make any difference in this case? Etc.

[real heath]

I think that's saying you can use the 1 material instance as you are getting information directly from the primitive. Without using CPD you would need a MI for each variation

Changing MI is relatively cheap (certainly cheaper than changing an actual material), but still a draw call and breaks batching, so avoiding them where possible is good.

[hidden dew]

Hmm.
But what about a HISM component, where every instance in the HISM uses the same MID?
I update parameters in that MID, but every instance uses it and (as I understand) all instances always have exactly the same values.
That's still 1, uh, draw call right? Even if the code is changing some of the parameters in that MID every tick

How do you make a MID that forces 2 draw calls?

Like, if I have 2 doors in a level that use a MID, what would make that require 2 draw calls?

If I am getting Lightmap UV overlaps despite telling it to generate new UVs, should I just increase the size of the UV?

[prime tulip]

Does anyone know how to fix the insane GPU fan blowing in packaged builds? Every single game or project I make in Unreal has user's GPU's blowing like they're about to enter the stratosphere. What is up with that anyway? I get that it's probably to do with too much FPS. But why don't I have this in other games where I get 150+ fps? What is different about Unreal that this happens? This has been bugging me for years now and would really love some info on this.

It's not like it's a big issue or anything, hence why only now I was like aight let's investigate this. But it's quite annoying to always hear your PC get super loud whenever I launch one of my projects. I can barely hear my music at times 😅

[spice ruin]

Try having them put in t.maxfps somenumber

And see if it stops?

[prime tulip]

I tried that already, my ingame fps is capped at 60 but still my GPU makes a lot of noise until I close the game

[fierce tulip]

if there are parts of the uv that are mirrored or overlapping themselves, the autogenerator can generate what it wants.
it cant re-unwrap those, so you'll need to do that yourself in a dcc

How do I make particles appear smoothly in the Niagara System? I added a Niagara Emitter to the NS, and in that Emitter I converted Lifetime to Float Curve and put the values in reverse, but now I can't see the NE

[cedar pawn]

probably not. since it comes with the license of usage and not for re-selling. thats what I know, some expert might know better

[oak patio]

Very license specific. Read the license for said assets. Some allow redistribution, some don't, some do if criteria is met.

If you don't know the license of the assets, or they were obtained via ue marketplace, then I wouldn't.

yeah but most of the cases like 99% they wouldn't allow, otherwise one person would buy and share with the whole world for free 🙂

How can I stop my game from freezing when loading a new level through BP? I am making an endless runner and need my levels to be loaded seamlessly.

[spice ruin]

Use async loading?

[jade surge]

I'm pretty sure that's not how seamless runners are made, not the simple ones anyway

[jade surge]

Couldn't type it because I was in an apex games, but iirc seamless runners just teleport the tiles infront of the player, the player doesn't even move, they just play a running animation. The world moves toward the player instead

[latent sonnet]

Even if I were to use the method of an in-place character, I believe I would have the same issue. My “tiles” are more like “chunks”. They’re full levels that get loaded the player reaches the loading box

When the player hits the loading box, the game freezes for a bit to load the next level

That’s the part I’m trying to smooth out

[jade surge]

As he said you can async that, but im pretty sure the landscape in the world is just an actor that can be moved

So you should in theory be able to teleport the Landscape and then spawn new foliage

I dont think constantly loading a new sub level is a good idea

Not to mention the further you go from 0,0,0 in unreal the lagging things get

Atleast that's what I was told, I never tested that theory

If that's true then an endless runner with a character running straight will not be efficient as the world is not unlimited?

@latent sonnet

My knowledge on this stuff is limited so hopefully I'm not emberassing myself. Although I do believe the information I'm giving is accurate

the entire Unreal Editor's interface relies on GPU to render every single thing you see on screen. Menu, dropdowns, the Details Panel, everything. That's why just having the Editor open gets your GPU's fan going. If you have 3D viewport panel in view as well, all the more.

Yes it will fire on the next frame. I believe it will fire multiple times per frame if it's a looping timer

does 'isoverlappingactors' require 'generateoverlapevents' to be true?

basically I'm trying to figure out a way to get a cone shaped overlap trace, one way is to enable/disable overlaps on a cone component the fly (I do not want the overhead of it having overlaps on permanently), but it is not robust because if I do enable overlaps and then check overlaps on the next node, I think the component first needs to tick, but there is no guarantee of a tick between nodes. So I add a delay, but this feels bad if moving at high speed as sometimes the overlap isn't detected.

There's no landscape or foliage in my project at all, so that's not really the issue. The chunks are made up of Actors and Meshes. I believe you are correct about moving further from 0,0,0 however it's a small project so I'm not concerned about it atm. As for Async loading, I'm not really familiar with it. As far as I can tell, I can't load my levels through blueprints at a specific location with it which I need

[latent sonnet]

My chunks look like this for example

Each one is different and the box at the end loads the next one while a box further down unloads the previous one

I need the next level to load at the end every time

[blissful steeple]

do i need to have a 86gb file of City Sample in program data / epic / etc and also where i create the project ?

[jade surge]

What im saying is spawn all of them immediately, and then teleport them to instead.

Instead of loading and unloading, just teleport the chunk to its next desired location

thanks for answering my question 🙂

[plush yew]

is there a node that return true or false if a client is in editor or not

[abstract lava]

nope not at all maybe you shud read it better xD

[real heath]

no, trading assets is not allowed. For more information read the Epic Content License agreement. It refers to this as "content pooling". The only time this is somewhat allowed is when a "business" (company or individual) has purchased an asset, and shares it with developers for the limited purpose of working on a company project. The contractors and employees are not allowed to use these assets on other projects.

You are also not able to make and sell a derivative work in source form, only as part of a published project like a game or film

Hi everyone, im a complete beginner on Unreal Engine, only have some basic knowledge of Unity3D. Im currently trying for a position as a Junior Game Programmer in a small company. And i only have a few days to present a small project that feels a bit daunting when i have so little time between a full time job and im currently moving houses too.
I was wondering if there is anyone who is willing to teach me and tutor me in the next few days, and possibly talking about a pay for the time taken from you.

P.S. Sorry if this isnt the right place to ask this, it seemd like a resonable channel to do so

[spice ruin]

2 days isn't enough time to really care any kind of project, especially as a junior.

Unless you're literally going to give them a reskinned copy of Lyra

that have to work well online too

I've ran setup.bat and generate project files but the file I need to apparently build this thing isn't showing up. according to https://docs.unrealengine.com/4.27/en-US/ProductionPipelines/DevelopmentSetup/BuildingUnrealEngine/ I need to run UE4.sln in visual studio, but it isn't being generated with the batch file for creating project files. Unless i've misunderstood some instructions there seems to be a problem. Can anyone give me some pointers as to what I'm doing wrong here? All I really am trying to do is get Unreal Enginge version 4.18.3 running on my system.

[wide crag]

you can't find 4.18.3 in the launcher...? are you sure?

[flat dawn]

Unless I'm missing something.

[wide crag]

what version is your launcher? go to settings

[real heath]

what the.......

wheres all the patched versions?

agreed, check launcher version

[flat dawn]

I'd assumed they were removed with the release of the new unreal 5 or something.

I guess this isn't normal then?

[wide crag]

definitely not

[real heath]

no.... they were most definitely not removed

[flat dawn]

Where does it tell my launcher version? I'm in settings.

[real heath]

down the bottom

[flat dawn]

looks the same to me

[wide crag]

🤯

[real heath]

strange. Maybe install 4.18.0 and it'll magically be .3

[flat dawn]

Well i'll certainly try that if you think that's a better idea then trying to install from github. I'm just trying to make sure I do this right is all.

I'd sure like to know why my menu is missing install options though.

[real heath]

i mean, sure you can install from github, but it's hard mode if you don't actually need/want source version.

to be clear: there are absolutely good reasons to use the source version, but for some people and projects it's overkill

[flat dawn]

Like I said, all I am trying to do is get the right version for this project. I don't particularly care how I go about it. Whatever is the most efficient way to get the proper thing I need. I just keep running into roadblocks for what I assumed should be a fairly simple thing.

[flat dawn]

Bruh

it actually did it

wtf

No idea why it didn't show the patch versions for me but I clicked to install 4.18.0 and sure enough it turned into 4.18.3

Hopefully there's no more issues but I guess sometimes the most braindead solution really is what you need. I was stuck in the mindset of "oh there's no way this could be right" and yet here it is.

Thanks man

Does anyone know if it's possible to edit visibility collision in editor? I want to remove the window frame from the visibility collision so that AI sight doesn't get blocked by the cross section.

The only way I can think of right now is to separate it into two meshes but this seems tedious

Hi Guys .... Does anyone know how to custimize(Resize or use an image) for the slider handle in widgets ? ... I'm trying to make a custom volume slider ... thanks !

[pallid olive]

hi guys, got some animation which the Z import translation is a bit off, how can this be adjust, is the only solution to import the animation for pre setting the z translation offset ?

[hasty mortar]

Hi guys, is it normal dat our builtData files are very large? The largest being 750mb. The levels in our game are arena sized (no crazy open world stuff).

[brave shard]

guys do you know a way to write math expressions in unreal engine?

im having a hard time finding the right font for it

do u have any experience with this?

[latent sonnet]

I'm trying to get an Enum State to change based on animation but, despite the notify being on frame one, the change is always delayed. Anyway to make it more accurate?

[wide crag]

where are you trying to write these expressions?

hey guys ! im getting this crash what does this means??/

[wide crag]

segfault means you're trying to access a memory location out of allocated memory. ways to fix: load fewer things, reduce the complexity of things being loaded, allocate more memory, check garbage collector is clearing space properly, use design patterns like object pooling to reduce memory fragmentation...

[full bobcat]

Thanks this crash I only got once

I created the widget in begin play and save it to a global UserWidget variable and in game over method I'm adding the widget to viewport
So I guess here is the problem

[wide crag]

you can probably have the widget present at all times but hidden when not needed, instead of creating it?

[full bobcat]

okay so its not a problem

Does anyone know how to fetch highscore from savegame instance and create a leaderboard using PLAYFAB

[tacit knoll]

I'm having some kind of issue with my game not using the computer's full potential. I'm wondering if anyone can help.
I've set it to high performance on hardware-accelerated GPU scheduling, and I've set Nvidia's power management mode to maximum performance. When I try to run the build of the game using an RTX 3090, I'm getting ~60FPS with around 60% CPU, 50% memory and 30% GPU according to Task Manager.
I'd like to have the game use more resources in exchange for better performance, does anyone have any tips on achieving that?

[real heath]

Is it vsync? r.vsync 0 in console

[tacit knoll]

Unfortunately it isn't clamping, the FPS floats around 60FPS, sometimes higher, sometimes lower. In the splash screen with very little going on it'll hit over 150.

What's bizarre is that some people with lower spec PCs are getting equal or better performance, which is why I think it may be something to do with the game not using what it can get.

[proven mauve]

Does anyone have any good resources for plugin config files?

The docs clearly state to define data in: [PluginName]/Config/Default[PluginName].ini, but that just straight doesn't work.

The only thing that works, is [PluginName]/Configs/Game.ini, which is unpleasant because it overrides the DefaultGame.ini in the project settings.

Additionally, the ., !, and + syntax isn't working as I expect; if I define testValue in project config, and then re-define it as +testValue in the plugins Game.ini, the test-value overrides, even though the + should filter that out.

Messing with - and ! in the DefaultGame.ini also doesn't work as expected, since it seems as soon as Game.ini exists (in a plugin), the project config no longer really works.

[spice ruin]

I'm using Default[PluginName].ini and it works fine.

You're removing the [ and ] right?

[plush yew]

hello everyone. It's written in assignment to submit Win64 Build of the game with a working executable in UE4? Which one is it debug or shipping client or server?

[charred bramble]

Yeah also thought it was something like 2nd Perspective or 2nd Person or something in those lines.

sorry, i dont think i explained correctly. ive tried in many ways but i cant find a way to write in text math experssions ( with math symbols and all)

[south quest]

Hi. Im pretty new to Unreal so Im still trying to get familiar with everything (literally just started yesterday). I was wondering if anyone knew off the top of their head why whenever I press the play button, I start the game from my where I last was when editing the scene, instead of playing as and starting at the location of the player I've made. The player is essentially just an unmoving, invisible actor in the scene I can collide with because of this issue, because I guess im not actually playing as the "player actor". I've created a GameMode blueprint that I have selected to use in the world settings, and have set the default pawn to the player I made. Are there any steps I might be missing anyone can think of?

[oak patio]

If you do the game mode step you don't need to place the character in the world, just a player start

[south quest]

Ohh, that makes sense! I guess I misunderstood how game modes work. Thank you for letting me know

[oak patio]

No problem

[dreamy wasp]

I'm looking for help from anyone who is willing. I have an issue with UE4.27 that is killing me.
I have chopped everything I could, but I still have this pulsing in the CPU, that I can not find/fix.
I have uploaded the information here:
https://ufile.io/f/gu40h
There is the Statistics panel image, size map, a video of the playthough with VRfps, and a file for the profiler (session frontend) where you can look at all the information. I am at a complete loss at how to fix this.
Please help.

[primal copper]

Can I somehow see in the World Outliner to which socket an actor has been attached to runtime?

[thorn wave]

Hey.
Can anyone please tell me how I can implement Goolge License Verification Library in my Unreal Engine project? Or is there any method that I can use in my UE4 project to verify whether the user has purchase the app or not?

[oak patio]

Please don't be one of those that makes a singleplayer game and needs internet connection because "How will we know if you stole it"

[thorn wave]

It's for my clients project.

[oak patio]

well that makes a lot more sense 😓

I take it this is for a mobile project? @thorn wave

[thorn wave]

Yes it's an Android project.

[oak patio]

Unfortunately I can't find much online about it, you see, I only know where to direct with steam verification sadly.
I hope someone else can potentially help you with your issue

[feral estuary]

Hi! Is it possible to run a game made with ue4 on some cloud solution that has no gpu (because cloud gpu is expensive)?

Or is there a way i can force ue4 game to use CPU for graphics?

[oak patio]

a cpu can only do graphics if it has an apu

if youre server in question doesnt use an apu (very likely to not), as i dont think any EPYC or Xeon CPU's have igpu's, then no

the real question is why this is required to be deployed on a server with graphics

[feral estuary]

i asked chat gpt and it claims the following

@oak patio

To run a UE4 game using the CPU to handle graphics, you can try the following steps:

Open the game's configuration file. This file is typically named "Engine.ini" or "GameUserSettings.ini" and can usually be found in the game's installation folder.

Add the following lines to the configuration file:

[/Script/Engine.RendererSettings]
r.UseSoftwareRendering=True

Save the configuration file and launch the game.

i don't know if this is relevnt

[oak patio]

And this is why we don't always trust chstpgt

Chatgpt*

[feral estuary]

so it's not correct?

[oak patio]

No. If the server doesn't have a GPU or igpu it can't do grpahics

I would still like to know why a server is required

[feral estuary]

it's complicated

i don't want to deal with dedicated servers, so i'm making a session based multiplyer game

but i still want to have a couple of instances which "emulate" dedicated servers in the same executable, and i want to host them on a cloud solution

but cloud with gpu is expensive, while cpu is cheap

not sure if you get it, doesn't matter tho

basically i want to host a session based game and leave it perpetually running on a cloud

on a cloud server

the problem is most cloud solutions with gpu are mega expenive. so i wither need a cloud server that uses some cheap gpu/apu...or force ue4 game to use cpu for graphics

does that make any sense? @oak patio

[oak patio]

it does, and your solution doesn't sound like a good idea

if you dont want to deal with dedicated servers, dont make a game that requires them is the best advice

[feral estuary]

our team already has a similar solution deployed on our private servers, and it's working flawlessly. now we're searching for a good cloud solution to scale

[spice ruin]

I don't get the difference between a headless dedicated server and a "server" that's just your regular game running on a machine in the cloud.

You're just wasting cycles on rendering when you don't need to.

Whether it works "flawlessly" or not isn't the point.

[bleak stone]

For a game where you die with one shot and can dodge is it better to make the enemy shoot by raytracing or projectiles?

[oak patio]

you can't really dodge an attack with a raytrace

its instant

unless you mean that kind of dodge where the attack just has a percentage chance to be ignored

which i personally think is a cop out

[bleak stone]

So better using projectiles?

[dreamy wasp]

You can raytrace, and let the enemy know it's being targeted, and have them randomly move away from the trace. this is done in several games. This way the play needs to be fast about targeting, and shooting.

If you want to be a dk to the player, have the projectile slower, and have the enemy move out of the way, only when the trigger is pulled by the player. boxing games used this method in the past.

if you are talking about the enemy shooting at the player, then a ray trace is instant, and the player is instantly dead, unless its a dice game (like X-Com) where there is a percentage chance to dodge. But if you want the player to be able to move out of the way, then either have a slow projectile, or a flash, or laser pointer hit the player just before the enemy fires. Helldivers does this well. check the high tech aliens. they have a sniper alien.

[thin tendon]

Depends on the level of realism you want and the needs of your game. A super realistic game would use projectiles with simulated weights and physics for accurate bullet drop. A line trace with a particle spawner is cool if you don't need that realism. Physical Projectiles are also good for game with slow moving projectiles like arrows or fireballs.

[bleak stone]

Nah, i want it non realistic

Enemy shoot bullet and the bullet just goes stright until it finds a wall

The thing is, my game is kind of like a shooter rougr like so the player only has a life and when he gets shoot its game over, so he will need to dodge the bullets of the enemy

[hybrid rose]

Im running into a problem in Unreal engine 4.27, Im using a auto dungeon generator with these to meshes I have made on blender but when it puts the walls and floors down my UE goes super slow with my GPU at 100 percentage. Can anyone help me out?

[thin tendon]

My advice is that if you are expecting your players to be able to dodge bullets. You may want to use slow moving projectiles.

[hybrid rose]

Im new to UE

[bleak stone]

How slow is "slow" exactly?

[thin tendon]

That is up to you really. Slow enough they can be dodged but fast enough to be a challenge

[thin tendon]

Obviously the more you have the more it is going to cost. So you want to start looking at performance optimisation and profiling. Things like LODs, poly counts shader complexity etc.

[hybrid rose]

ok, Ill try and find some videos on yt. Thx!

[dreamy wasp]

Slow. like under 500 max speed.

[bleak stone]

That's...really slow

[dreamy wasp]

yt is the best for that. You might want to look up instance mesh.

[hybrid rose]

Instance Mesh?

[dreamy wasp]

slow enough to dodge., but fast enough to make them get hit, if they dont.

[hybrid rose]

Sorry Idk anything about this stuff

[thin tendon]

It is going to be a bunch of stuff mate. Instancing can help a bit. But it is only 1 thing on a massive to do list.

[dreamy wasp]

yeah. Instanced mesh. those will make your game run smoother because its just one draw call. but you can't have them as the whole level, because that would be a huge draw call.

Low poly. small textures. look at LOD for texture as well as mesh.

Spawning, tick, high poly count, are all killers for fps

[hybrid rose]

ok 👌

[dreamy wasp]

and math

math sucks in unreal

stupid math

[spice ruin]

Not really...

[thin tendon]

The trick is to go in with a less is more mindset. Do I need this model to be 100k triangles? What is the most I can reduce it and keep it looking nice? Do I need that part of the level loaded right now?

[hybrid rose]

I wanted to do a dungeon crawler for my college flinal but With all of this I dont think ill have enough time.

[dreamy wasp]

stick with lo poly low texture to start.

plenty of dungen crawer tutorials on yt

[hybrid rose]

Ok, thanks for the help! @dreamy wasp @thin tendon

[dreamy wasp]

hey slim

are you any good at profiling? I'm having an issue with a pulse, in my game. I can't figure where it's coming from.

[thin tendon]

I'm still kind of average. I get by with basic understanding and google.

[dreamy wasp]

I can't find much info on the profilers

[thin tendon]

What is the issue though?

[dreamy wasp]

I'm down to no dropped frames, and I keep lowering the Green, but I can't get the orange to get any lower

When I profile, it tells me I got Sht Tone of Stall wait sleep

which means it's waiting for something to get done, but I can't figure out what.

[thin tendon]

Yeah I seen this question before and didn't answer because I wasn't familiar with what you were using to collect the info. I usually just use the editor visualisers to figure stuff out.

[dreamy wasp]

This thing is fpsVR.

[thin tendon]

But re-projection sounds like it is having to render something multiple times.

[dreamy wasp]

the profiler gives me this

stall sleep self wait for event. not helpful

[dreamy wasp]

lol. nope. thats not what it means.

Thats a VR thing. it means it is faking a frame.

Instead of rendering a frame, it fakes it, to fill in the gap. If it can't do that in time, it drops the frame intirely.
Best is low re-projection and no drops. 20% is fine. 50% is bad-ish. 60%+ is not acceptable.
I'm down to about 30-40%

[thin tendon]

So why would it need to fake a frame then?

[dreamy wasp]

in VR people get sick if the fps drops below 90fps.

[thin tendon]

So its faking frames when the frame rate drops?

[dreamy wasp]

yes.

If it feels it can't render the propper frame, it render the next frame, then blends frame 1 and 3 to give you frame 2

[thin tendon]

ok so then the easy solution is to not focus on the reprojection figure. But all the improvements you can make to increase the frame rate. To eliminate the need for faked frames.

[dreamy wasp]

The drop is when it passes by frame 2, before frame 3 can be rendered.

[dreamy wasp]

yes. you want the frames to be as easy to render as possible. So I do very lo poly, so there are less triangles to gather. I do low texture so there is faster load time, I do no shadows so, no shadow pass, and I do fully-rough so there is no reflections.

You can check my tirangles. I chop and Chop

[thin tendon]

Also to depending on the style of game. You can use motion blur to hide bad performance a little.

[dreamy wasp]

motion blur is bad in VR.

its why people like 120+

There is a selector called Round-Robin that helps. It renders a single eye at a time. Left right left right, instead of both eyes every frame

You can also turn off the spectaor render, but I don't know how to do that. So no 3rd render
