[tawdry basalt]

I am spawning in object such as walls at runtime but getting a weird visual glitch at times when either turning quickly or moving around a corner, where a part of the wall is invisible for a split second, and I can see the sky, any one have any ideas what may be causing this?

[fierce tulip]

@latent moth while not really a nade shot, there are some nice water particles in the infinity blade vfx free pack on the marketplace.

@proven oxide while there is still a place in cascade, its better to focuss on niagara from now on, while knowing cascade might help a bit, i'd focus more on learning how to set up textures, shaders, and meshes for vfx

[fallow ginkgo]

Is there any other way to install UE4?

[fierce tulip]

either install binary, or from source

[fallow ginkgo]

Which site?

[fierce tulip]

you are only legally allowed to download it from unrealengine's own website

[latent moth]

thank you luos i was looking at those but haven’t seen anything re a splash, more like dropping water or such

[honest rover]

Can I ask for tech support in this channel, or is it just for discussion?

[frosty copper]

You can, but anything lengthy or specific would be best aksed in the channel most appropriate

[honest rover]

Alright, I think this question is pretty general. I keep getting the Texture Streaming Pool Over xxxGiB Budget message.
Every solution on the forum is to increase the pool size, but it keeps growing, so how do I reduce it?

[frosty copper]

🤔 does it need to be reduced?

[honest rover]

It went from 600MB, to 800MB, to now 1.103GB over budget.

Like if your sink is plugged do you buy a bigger sink or do you try to unplug it 🤔

[frosty copper]

Non power of two textures will cause issues.

And the "never stream" checkbox is arse upwards apparently; unchecked means its only loaded when needed,checked : its always loaded

[fierce tulip]

no

unchecked it means it gets loaded whole before its shown, checked means a lower mipmap is loaded and shown while a higher mip is being loaded

[honest rover]

Ah yeah, I saw this thread, but didn't know how to find where those options are

[frosty copper]

Well, there ya go~! :p

🤔

[honest rover]

Hey Yoeri, I follow you on twitter 😄

[frosty copper]

Power of two isnt an option, its the pixel dimensions of the texture

And, if i had to guees, id imagine the never stream option is found inside the texture viewer window

[fierce tulip]

yup

and there is a power of two option, but it just adds black edges to a texture to make itpower of two, instead of just resizing the texture. which.. i find odd

[frosty copper]

.... Well, that's new to me. XD

[fierce tulip]

been there for ages :p

[frosty copper]

Ive not been using the engine for ages unfortunately

[honest rover]

Could I also just disable this instead of going into every texture?

[fierce tulip]

if you want massive longer loading times, sure

[frosty copper]

Life has pulled me away from it, and ive been trying to code a launcher for Linux in the mean time :p

[honest rover]

Well thank you, I'll try unchecking the 'Never Stream' options.

Also, is anyone familiar with the image I posted in #cinematics ? Not sure how to google this problem.

[frosty copper]

Making sure all textures are Po2 will help a lot more afaik

[honest rover]

@frosty copper All textures are from a pack, I don't think I should edit those

[frosty copper]

Any non Po2 texture is always loaded by the look of it 🤔

The power of fwo option luos mentioned.

But that will be the biggest contributor to your pool size issue

[proven oxide]

@fierce tulip I am using the latest engine but it appears to be using cascade, how can i learn the niagra if its not in the engine?

and I am using a texture for fire, but its coming out as squares, how do you make it look like fire, all the video tutorials load up pre prepared materials they never show how they are done

[grim ore]

IF you want to use niagara you turn it on in the plugin manager

https://docs.unrealengine.com/en-us/Engine/Niagara the first guide is literally called "Enable the Niagara Plugin"

[fierce tulip]

@proven oxide I have a plethora of tutorials on youtube, but it'll take a while before you get the hang of making shaders for vfx. its not just a few sentence solution, and yea, you need to enable niagara first

[true leaf]

also im running into an issue here... Im using a skel/vert type emitter for the first time but the 'Associated Bones' field is not working at all !!! even if i make it blank , the particles spawn ALL OVER the actor and if i make it a value bone name, the particles spawn ALL OVER the actor

what is up w that :[

[fierce tulip]

https://www.youtube.com/watch?v=-pyTw-45Mfw that should help somewhat.

[true leaf]

yeah i followed that

to a T

what in the world

how is that possible >.>

no valid bones

[grim ore]

well no valid bones because you didnt set it, it's none by default so nothing wrong there.

[true leaf]

if i put in a crazy bone name like crazy_bone_name55 then it still works

fire all over the dude

😐

[grim ore]

I dunno man that is weird for sure, I just tested it and it worked fine here https://i.imgur.com/7phM23k.jpg

[fierce tulip]

poor mannequin

[grim ore]

It's his jorb to get burned alive!

[hot drum]

I'm so confused rn

This code right here is in a class BP for a cannon that fires some fire balls

I also have another separate BP That is a mushroom, that bounces the character up when he hits it

For some reason

the red outlined thing, right after I added them

caused the mushroom bp to launch the character every 4-5 seconds

playing the mushroom sound

I have nooooo idea why this is happening

the mushroom is not linked to the cannon at all

I've also looked in the BP during gameplay for both, no activity is happening in the mushroom

[inland lintel]

the fire projectile could have something

and use a timer

[hot drum]

what event do I attach it to

[inland lintel]

attach a new event called anything, dont attach beginplay

[hot drum]

will it just automatically start when I play?

[inland lintel]

yeah, beginplay sets up the timer and if its looping, the new event will loop

[hot drum]

I tried a custom event

I have no idea how it works obviously lmao

[inland lintel]

it's just the red line that goes on the new event

the white still goes on beginplay, to start running the timer

[hot drum]

o

ok

the timer works no

w

but i'm still bouncing

[inland lintel]

there's something else running the mushroom code

[hot drum]

I've checked it up and down

nothing connected

ok

so now I just found another enraging problem

whenever I teleport to the cube so I can get to the room I need to get to

the cannons just

stop

and so does the bouncing

oh wait no

[inland lintel]

sounds complicated

[hot drum]

never mind

it just plays o n c e

[inland lintel]

the white is the execution, follow it and you find your problem

maybe you didn't put the spawnactor function on the new event, the event that should be run with every timer time

[hot drum]

.>

[inland lintel]

that's the problem, the spawnactor goes on the white line of ea Event

your mushroom code must be somewhere else

[hot drum]

yay so uhm

it works again

but I'm still bouncing rip

here lemme send pic of the mushroom code before I go

[inland lintel]

it's looping the animation. when BeginPlay happens is at the beginning of the Play, when the game starts, so it's looping all the time

correction, BeginPlay happens when an actor is spawned, in this case, the actor exists at game start, so it's happeneing from there

actor = the mushroom

wait, now I'm not so sure

maybe it's about the overlaps

right, so the actor, the mushroom, must be overlapping any other actor to play the animation. you must check that the overlapping actor is actually the player

in this case, instead of having GetPlayerCharacter, connect the OtherActor

to Object of the Cast

[spark wolf]

So I got a model made. Animate it then import into Unreal for results?

[pallid compass]

sure

[calm sphinx]

Anyone here have knowledge about epic's new physics engine: Chaos ? Has anyone made it work successfully from source code of master branch?

I only got new blast destruction plugin working with chaos, but other physics systems were failing to work with it. I don't know if there is a plan to support an only chaos mode for 4.22 .

[plush yew]

whats a good beginner game to make other than pong?

[zenith flower]

Answer to my own question:
If the match is put into InProgress before the second client can get its controller, it wont have begin play called on it.

[grim ore]

make a simple collect game. Make a level, put X items in the level, you have to collect the X items before the timer ends and get to the exit. Teaches you most basic game loops you need.

[plush yew]

so what would a tutorial be called

[spark wolf]

Hmm

https://www.youtube.com/watch?v=VJj6rQpktyI&list=PLZlv_N0_O1gYdhCvvMKGpCF6LCgBz9XeS Not quite the same

But it's a time trial checkpoint system game

Or you could try to remake the first Super Mario Brothers in side-scroller. lol

Has all the necessary elements beyond collecting all coins but that's a minor tweak

[novel ember]

did something happen to Submixes in UE4.21.2?

I had to verify my engine and now the submix references have a gray thumbnail instead of an orange one and my listener delegate doesn't seem to be getting called

[zenith flower]

Why on earth do I keep finding weird issues

How the hell am I supposed to work with this?

[manic pawn]

what's the issue

[zenith flower]

All my clients are calling begin play on the first players controller

[manic pawn]

makes sense

clients only know about their own controller which will have id 0

without the context for these 6 log messages its hard to say anything more

[zenith flower]

You are right, im looking in the wrong place

@manic pawn
Thank you, this was running on the server (I forgot to change old code)

[grim ore]

Yeah that screenshot is correct no issues there.

[zenith flower]

im like 99% done converting my game into network compatible code, so i'm just weeding out the few places I forgot to "multiplayer"

[manic pawn]

oof that doesn't sound like a fun activity at all

[novel ember]

okay well i'm one step closer i guess

[zenith flower]

I've kept the game "barebones" and "modular" over the last two years, because I knew this would come. I've only spent about 3 weeks getting this all working with replication and all

[novel ember]

why would the new audio engine crash the editor a couple seconds into a game starting?

by game i mean simulating or new window / standalone game etc

it's been fine this whole time and then yesterday it just started crashing even without the events actually being called in-game

[pallid compass]

Did you update recently?

[severe glen]

hi there

I m working with material editor on unreal but compile shader is not working fast. it is slow

I dont know what happened

it was work faster then now

[novel ember]

I updated around this past monday to 4.21.2 i think but this issue didn't show up until last night

i verified the engine version and it specifically seems to be the new audio engine that makes it crash

it can play fine using the old one

trying to use the envelope listeners for the current build though

uninstalling visual studio doesn't appear to fix it either

[pallid compass]

You need debug Symbols

So you can check the callstack

and see what is going on

[true leaf]

okay well i am getting closer to solving this particle emitter on surface issue !!!

That same test worked for me too, i can make an emitter only appear on a single bone of an actor

The issue is .... my actor has a sub-component which is a Skeletal Mesh

and I am trying to put the fire just on the one bone that is in THAT skeletal mesh

and I cant figure it out for the life of me...

its a sword

[pallid compass]

Attach Particle emitter to a socket on the bone

you need to add a virtual socket for that

[true leaf]

it has to be to a socket ? what about surface rendering

or vertex

[storm burrow]

Not getting messages like "Compiling Shaders" or "Lighting needs to be rebuilt" in my viewport anymore (top left corner)

[pallid compass]

I doubt it

[storm burrow]

anyone know how i can fix this?

[pallid compass]

Just use a socket or something

Cant 100% remember

[true leaf]

then its just a single point of emitter spawn

: |

hmmm

OH I GOT IT

I had to attach the emitter TO the actor as a subcomponent

the emitter couldnt just be in the world

it cant scope down into the actor's subcomponents without being a subcomponent of the actor itself

maybe -.o

[novel ember]

@tulip vault did you accidentally DisableAllScreenMessages or something?

alternatively try the drop down and make sure nothing's unchecked

@pallid compass I've got debug symbols now but I still don't know what to make of this callstack

although bizarrely now the game survives for a few more seconds before crashing

[pallid compass]

paste the whole thing in here

or pastebin actually

[novel ember]

https://pastebin.com/gdkKkYE2

[true leaf]

welp i gave up for now. Im not sure its possible to do a vert/surface particle emitter on a bone thats in a subcomponent of an actor's mesh (weapon) so i am just 'cheating' and making a regular old cylinder emitter to make it look like the swords shape is kinda glowing >.>

[pallid compass]

Il take a look now

@novel ember Your AmbisonicsMixer is not valid for some reason

So something is not setup right

[abstract relic]

Jesus, how long have you been playing with unreal Toast? I’ve never seen someone learn a new engine this quickly.

[novel ember]

currently i'm only worried about getting it running on Windows

what do I need to do though? i'm confused as to what between last night and the time before would have caused it to just give out like that

[lunar bobcat]

put in a request for help in #blueprint

[pallid compass]

You can toast

But its not handed to you on a plate

[storm venture]

so im stumped, been at this for a while now.
im using a cel shader in my post process material, and when the viewport is moved to anything other than the default size, this happens:
(left is normal, right is when i move the viewport's side in a bit)

[novel ember]

do you have TexCoord plugged into your UVs?

it's something to do with preservation of the aspect ratio it looks like

[storm venture]

it looks like all the UV coords plug into this:

this is a cel shader i purchased on the marketplace.
it used to work, but one of the newer updates caused this to start happening

[true leaf]

@pallid compass yeah ill have to come back to it

indeed its quite an advanced topic

lol

[storm venture]

one other person had this issue before and they solved it by adjusting quality settings back and forth, although that didnt work for me, unfortunately 😦

[true leaf]

so some part of the processor is not considering the viewport size ?

[severe glen]

ok I found a video about my problem which unreal is not do fast shading compile on my pc

https://www.youtube.com/watch?v=Q_E45cUha2s

how can I solve this? I have ryzen7 2700x

[true leaf]

@abstract relic yeah to be fair ive only been using unreal for 6 weeks so i cant expect to understand everything so fast 😛 but ive come really far really fast im happy. Im a programmer tho so, mostly javascript/ruby. My computer does pretty slow shader compiling too btw, are you sure that isnt just normal ?

[shy silo]

So I’m a beginner and I was trying it think of a small project just to get me to use the engine and was wondering, how hard would it be to make a game that loops in blueprint

[true leaf]

you can make an impressive game with just blueprints , esp if you use some plugins

[north shale]

is it posable to set the walkable floor angle to be calculated off the pawns Z instead of the world Z in blueprint

[fierce tulip]

@true leaf ofcourse

[novel ember]

well now that i've been backed into a corner trying to get this demo out i finally had to use my brain and figured out a simple workaround for the audio visualizer

instead of a progress bar tied to amplitude envelopes I just make an image of the .wav file's amplitude, turn it into a 1D texture and pan it based on how far into the song it is

obviously a loss of precision but it works for now

[hazy sparrow]

So, I'm not sure if this breaks the rules or not but I've got a team together but none of us know how to work Unreal Engine. We'd really love someone with some experience to teach us how to use the program and get to work on our first game.

[fierce tulip]

you could try #looking-for-talent

read the pinned message

[hazy sparrow]

Ok, thank you for the help!

[shy silo]

can someone tell me how to add the first person character to a blank template?

[abstract relic]

Import >>> add packaged content (or something similar to that name)

[shy silo]

import in the content browser?

[abstract relic]

Yes

The lovely giant green button. It’ll give you options to import templates

[shy silo]

ohhh add new, not import got it thanks

[abstract relic]

Whoops 😅

[shy silo]

no worries

[true leaf]

i get this a lot when packaging /cooking my project... the fix i think is to just rename my structs. is this a bug in unreal or what

[zenith flower]

beginplay is useless trash once you go networking.

[true leaf]

i found this lol https://answers.unrealengine.com/questions/337507/unknown-structure-error-when-cook.html

[abstract relic]

bug it is

[zenith flower]

@true leaf From my experience, I would go into each of those referenced blueprints and:
Do a search for the referenced structure: Delete the structure pin/node
Re-create the structure pin/node, and reattach.
Then refresh all

A possible quick fix is to just "refresh all" in each of those blueprints

[true leaf]

ty !

epic pls fix

lol

[zenith flower]

It usually happens when you move the structures or rename them

[abstract relic]

Look at how old the issue is 😜

[zenith flower]

they don't like updating the references correctly

[dry moon]

Yeah I get that issue as well, never renamed or moved it

[zenith flower]

(if you store a structure in a blueprint as a variable, and then cross reference it between blueprints, and then move one of those blueprints, or rename, you can get the same effect)

It will also happen if you add/remove pins to a structure (sometimes)

[abstract relic]

What’s the point of a redirector then?

[dry moon]

Still stupid

and needs to be fixed

[zenith flower]

I just usually, "refresh all nodes" in the effected blueprints
That will usually "error" out the stubborn pins. Then I just manually delete and re-create those pins/nodes

yea, they will fix it as soon as they get MAP variables working over the network xD

[dry moon]

I still can't get fucking images uploaded to trello

is it just setting a httprequest content as string as the JSON paramaters for the file

so confusing

https://gyazo.com/5de2e197e048bc28298372be059ad473

I can add a file with a simple POST through a URL here with the correct params

just won't work with HTTP requests

I sent it as {"name":"bugreportss.jpeg","mimeType":"image/jpeg","file":"FILE BYTES HERE but it cuts off

[shy silo]

one more question, I want to destroy a sphere when It hits a specific wall, so I have the on actor hit->destroy target actor, but it only works when I run into it, not the sphere, how do I fix this

im sure this is very basic sorry

[clever kelp]

hi guys, my homing projectile (sphere) looks like an egg :D, does any one knows why it's possible?

this is how it looks inside

[plush yew]

guys i need help
i uploaded a game to google play
and ads still not shows up

[zenith flower]

HOW IS THIS POSSIBLE!?!?!

[manic pawn]

bp debugger is weird

they're not actually different

unless you called these from different places and managed to change owner inbetween ...?

[zenith flower]

nope

[weary basalt]

Remember that non execution pin Nodes get evaluated when they are called by an execution pin node, so the value they hold may go stale or not display correctly.

Honestly, i never use the BP debugger, its to buggy 😛

[manic pawn]

I wonder how bp debugger even works

if you pause like a blueprint event called from a native method

[weary basalt]

If you want to debug Blueprints, use PrintString.

[manic pawn]

it would have to freeze the main thread for that to not die

but then how can the ui run 🤔

[severe glen]

does somebody know how can I increase the number of ShaderCompileWorker.exe ?

[manic pawn]

what?

[severe glen]

my shader compiling is working so slow

when I check it from task manager I see that ue4 spawn only one ShaderCompileWorker.exe

[abstract relic]

That’s

Not how performance works

[north shale]

does anyone know how i can create a calculation to check the angle of the surface my character is on

[severe glen]

@abstract relic Finally I found the problem and I solve it. the problem about a software which is Incredibuild. I just delete it.

[fleet cedar]

Does anyone have good recommendations for ways to check the performance on C++ code?

I want to compare the vehicle physics code that I wrote to the UE4 ones

[pallid compass]

Check how much ms or how long it takes to execute?

[delicate tusk]

Hey, does anyone know a good method for ensuring struct values remain updated across various BP's? My idea was to send them all to the game mode BP, and call references from there, will this work or is there a better method? Thanks!

[proven oxide]

depends where its needed

i was reading, if its global then gamemode, otherwise possibly playerstate

https://answers.unrealengine.com/questions/122429/gamemode-vs-gamestate.html

https://docs.unrealengine.com/en-US/Gameplay/Framework/GameMode

[delicate tusk]

Thanks @proven oxide , I'll check those links out

[fallen gust]

@north shale you're going to need two raycasts from the character and some math.

[dry moon]

Finally got bug reporting to work with this god damn API

[grim sinew]

I don't think a single user would call a bug they report anything but high priority

[dawn vessel]

Personally, I choose high priority all the time when Bug Reports come in with that Button 🤣

Fix the damn thing ASAP! 😃

[dry moon]

That's why I got it set to Low Pri as default so I don't get spooked if its like "rock is floating above ground here"

[grim sinew]

"Yes, this bug that affects me is low priority and I don't mind if it never gets fixed" - Nobody

[dry moon]

Well game breaking stuff should be first 🤔

[dawn vessel]

What we're all trying to get at is... No one is going to use Low Priority 😃

[dry moon]

Well I'mma hope people use it correctly

[grim sinew]

Also, expect high priority to be a bunch of troll reports too

"High priority issue - Your gun doesn't shoot waffles"

[dry moon]

I'll just move it low when I check the list, no biggie

[maiden swift]

I don't think you should have a priority dropdown at all on the form. The developers should set that, not the user.

It's likely you'll have to change it after the fact anyway. Most users will assign an incorrect priority.

[dry moon]

yea ik, its pretty much a few of my testers trying it out so really only for them

I'm hiding it in public demos/builds

[maiden swift]

Ah I see.

[fallow ginkgo]

Ue4 uses c++ right?

[dry moon]

Yup

[plush yew]

Do you guys know how to automatically brighten a map without lights through usage of a sort of fullbright technique?

[opal spade]

Looking for help, I'm not sure exactly where this falls under but I'm having trouble with a level. I made a landscape and when I add foliage the performance takes a hit, frame rate drop, etc. It's any kind of foliage. It happens exactly when I begin painting on the foliage using the foliage tool.

1. The level is size is at the maximum space allowed (could be the problem)
2. I'm using foliage from several different sources on the market.

If this isn't the correct place please let me know and I'll move it to the correct channel. Thanks for all the help!

[toxic hatch]

I was wondering if anyone else has had glitches with the newest version of unreal engine where you bake your lights, click on something and it looks really weird/wrong. But then sometimes it goes back to being correct if you do stuff like changing the intensity of a light.

[cerulean nova]

@opal spade Lower your Editor Preview settings could help. Dont forget that making games often takes a more powerfull computer because u tend to see alot more then ingame however it depends. Whats your GPU ? Mine for example is also quiet old and gets in Trouble with foliage quiet easy because of the shader complexity (to dense foliage) because the engine "masks" out the foliage and the more layers are on top of each other that are "invisible" the more complex does it get Therefore more performance hit. Try to make it not to dense i know i know it looks awsome and all that but performance always comes first ^^ The most beautiful game is still shit if it doesnt run smooth 😃

[fallow ginkgo]

Hello, I want to dowbload UE4 but for some reason my epic games launcher isnt working. Has anyone got this problem before? I tried giving it administrator priviledges but It wouldn't work. I also tried repairing and reinstalling it but it still isnt working. How do you fix this issue? Help will be appreciated.

[opal spade]

@cerulean nova I'll definitely try that next. I am due for an upgrade, I'm using a 1050Ti and it's done me solid work until now. I'll PM whether your solution works or if I find a different solution. 😃 Appreciate the help!

[cerulean nova]

1050 should be fine tho i would then say its either the density or there is something wrong with the foliage. Quick Tip : Hit "Play" in the Editor and when ingame Press F5 that may give u a look on whats maybe the problem ^^

[fallow ginkgo]

Can anyone help me?

[weary basalt]

You need to provide more info man, just saying "its not working" helps no one.

HOW is it not working.

[fallow ginkgo]

I downloaded the installer for the epic games launcher. It work fine. But when I tried to launch the game it doesn't do anything.

The first time I tried launching it, it starts updating then it closes.

Is this enough?

[weary basalt]

Is this for a game you bought:?

On the Store?

[fallow ginkgo]

No, its the epic game launcher for ue4

[weary basalt]

So your Editor isnt opening is what your saying?

You may need to check if its crashing. There will be some crash logs in the Saved folder

[fallow ginkgo]

Editor? I dont think it is

Wait

Epic game launcher cant open

So since i cant open it i cant download ue4

You still there?

[toxic hatch]

what happens when you try to open it

[fallow ginkgo]

Nothing happened

The firsr time it says it updating then closes. Once i open the launcher again it doesnt open ever again unless I reinstall it. And after reinstalling the same thing happen

[grim sinew]

Running as admin doesn't help? Letting it through your firewall?

[fallow ginkgo]

Running as admin doesnt help

[grim sinew]

C:\Programs Files\Epic Games\ no crash logs you can find anywhere in one of the directories here?

[fallow ginkgo]

Wait let me check

[grim sinew]

It also has a debug mode that I found out about through 5 seconds of google you could have tried

that will output all the info to a log and probably say what went wrong

[fallow ginkgo]

Can you give me the link?

[tribal pebble]

any cheesters that use Html5 Packaging in ue4 .-. ?

[atomic sandal]

hello anyone can help me with floor

[frosty copper]

That's... Vague.

[atomic sandal]

hey

[north shale]

how do i get my guy to walk on the surface instead of floating https://imgur.com/a/w0ZscWw

[grim ore]

any reason why he is floating?

his capsule should be way smaller than that gap and I assume the collision on the terrain would be way closer to the visible mesh

[runic fern]

put the player in the middle of capsule

[north shale]

the reason for him floating is cuz thats where the collision mesh is i don't know how to make it more accurate thats what i m asking help with

he is

[tawdry sierra]

hello guys

[runic fern]

Hello

[abstract marsh]

Not sure why everyone found it weird for me to ask for game pitches

[tawdry sierra]

i want to change a character i spawned with a buton

[north shale]

https://imgur.com/a/0tGQ3e6

[abstract marsh]

I'm looking to see how people present their games

@ me

[tawdry sierra]

basically i want to transfor my character/ change actor

[runic fern]

make capsule littlebit bigger and try

@tawdry sierra you wanna change the button or the character ?

[grim ore]

@tawdry sierra that code would never work because when you hit your E button nothing happens, nothing is hooked up to the execute wires on the Flip/Flop

[north shale]

i imported a blender .obj sphere and when i walk on it the character floats even though its in the mid of its collision box

[tawdry sierra]

i want to swap an actor with another one

[runic fern]

connect flipflop with the branch

[tawdry sierra]

with a button press

[runic fern]

Flip-Flop A and b

connect it to the Branch and try

[tawdry sierra]

what about the event play?

[grand knot]

i have a math problem

who can help

[tawdry sierra]

ooo emud

[grim ore]

@north shale what does the collision lok like on your surface then?

[grand knot]

i have a animaiton set to play speed on velocity

but i want to make sure max play speed is 100% not higher

so i need a math equesion that limits it to 100 while still using velocity

any ideas?

[north shale]

what do you mean

[grand knot]

i have a custom running animations play speed set to play depending on characters forward velocity

tho i dont want it to play over 100% speed as the velocity can go as high as 25000

[north shale]

the collision looks like its bigger and out of place from the visual mesh

[runic fern]

Emud im not sure about your question but you wanna set the player walkspeed 100 limited

but with velocity can be more than 100

with velocity value

[inner mountain]

@abstract marsh at first, you have to decide what's your target for pitch. Is it publishers/investors? Or gamers? developers?

@abstract marsh also here is an old but good article about pitching http://www.tinybuild.com/how-to-pitch-your-game

[grand knot]

ns it can be more then 100 thats the problem

hence we need a math solution that still uses veloity but limits it to 100

[runic fern]

you can Set the max walk speed at 100

but you can use Add to the variable of walkspeed

or you can use condition when velocity reach for example 1000 the max walk speed will increase

if the velocity reach 1000 set max walk speed to 500 and if velocity decreased set max walk speed to 100 again

[north shale]

is there a way to visualise the collision mesh?

[grand knot]

i dont think you understand man

[runic fern]

navigate your worldoutliner @north shale

[grand knot]

i want the animaiton speed to allign with a custom run event

[runic fern]

oh i thought the movement speed xD

[grand knot]

so if character is walking 1km i want animaiton to play at 10% and if hes flying at 25000km i want the animaiton to play at only 100%

[north shale]

your saying walk around?

[inner mountain]

@grand knot use Clamp node

[grand knot]

oh shit didnt even think of that

see guys

[runic fern]

@north shale no i mean check the colliosion on the worldoutliner maybe its box not visible or something

[north shale]

when i say visualise i mean like this https://imgur.com/a/VBn5MRg

[light bobcat]

how to undo XD

[north shale]

ctrl Z maby?

[grand knot]

still how would i use clamp for animaiton play speed to be same in percentage as character velocity

[light bobcat]

okay thanks I forget it ever time XD I starting to make my own game like 2 mouthXD

@north shale

[north shale]

@runic fern

https://imgur.com/a/VJtOFEg

[inner mountain]

@grand knot how are you playing your animation? Are you using an Animation blueprint?

[north shale]

when you say "its box not visible" you mean the eye?

what @light bobcat ?

[runic fern]

thats weird

[north shale]

what im wanting to know is why my guy is floating above the visible mesh

what ist like is as if the mesh as been estimated then thats the collision so it goes down a bit in the dips and up a bit on the peeks https://imgur.com/a/xxN927A

[grim ore]

the visibile mesh is not always the collision

open up the mesh in the editor and click on the collision button to view the collision

[north shale]

https://imgur.com/a/bxm5dir

[grim ore]

find your mesh in the editor, double click it to open it up in the mesh editor, click the collision button at the top

[north shale]

when you say fined the mesh you mean is the components tab?

[grim ore]

no I mean find the mesh in your content browser, that above is your blueprint

[north shale]

sorry im new and have only been using unreal for about 3 weeks

aa

[tawdry sierra]

question: How can i make a mesh that doesnt recieve light from a specific point light?

[grim ore]

change it's lighting channel?

[tawdry sierra]

how do i do it? im only 2 months into ue4

[north shale]

https://imgur.com/a/z5xIwUY

[grim ore]

on the mesh type channel in the search details, or go down to the lighting section and open up advanced

[tawdry sierra]

i see

there are 3 channles

now?

[grim ore]

@north shale that is the blueprint, is says blueprint class at the top. I would guess the one to the left of it that says planet is the static mesh

now what? The light emits light on a channel(s), the mesh accepts light on a channel(s).

[north shale]

no thats a nether blueprint

[grim ore]

if you want the mesh to accept light from everything else but that one you need to set that light on another channel and exclude that one mesh

and then tell everything else to use that one channel as well

[north shale]

aha

[grim ore]

then I don't know. You imported the mesh so I don't know where you put it. Use the filters at the top of the browser to turn on Static Mesh if needed

[north shale]

https://imgur.com/a/87T0c85

found it

[grim ore]

I want to say offhand that the mesh is super duper tiny

[north shale]

yes it is 😄

i was just wanting a quick mesh i could check to see if a peace of code worked on

im trying to get the angle of the surface in on because the default wont work

in= im*

[grim ore]

firing a line cast down then getting the normal would do that but your collision might get in the way if it's this broken

[north shale]

ya

😄

so now that im in the mesh editor do i need to do something specific?

[grim ore]

click collision then simple and it should show your collision

[north shale]

kk thats so simple for me so i put it to complex now how do i apply this to the actor?

[grim ore]

complex is not going to work for that, simple is what your character is going to use. if simple is not correct then you need to fix it

[north shale]

gree is simple https://imgur.com/a/WRYBKYg

green

light green is the complex https://imgur.com/a/LtPgFOa

[grim ore]

yes that top one is what you are colliding with so you need to fix it in your 3d program or create new collision in UE4

[atomic sandal]

So is there possible way in Ue4 that i can sent file

[lofty hollow]

Hey moving around in the editor is extremely slow for me, anyone knows how to fix this?

[north shale]

so? fix it hum... thats going to be a pain cuz i dont know where to start XD

[grim ore]

@lofty hollow top right corner of the viewport is the Camera Move Speed if this is the issue

[lofty hollow]

oh thank you!

[grim ore]

@north shale fix it however you created it in your 3d program or use Collision -> Delete Collision then Collision -> Auto Convex Collision the hit apply on the panel that pops up and see if it can make you a new one

[north shale]

have you used blender?

[grim ore]

nope I am not an artist

[north shale]

ya its a pain 😄

dont use it

[grim ore]

try having UE4 create a new one then like I listed above

[north shale]

kk

[honest vale]

now this is cool https://www.unrealengine.com/marketplace/spline-mesh-solutions

[north shale]

kk its made me a new one and its not 100% perfect but its tones better, but now how do i apply this to the actor?

@grim ore

[grim ore]

the world or the player? the player doesn't need it

the player just checks the collision of the item it is on so fixing it on the planet should make it better

[north shale]

i was wondering how to applt the changes on the mesh to the object that uses the mesh but it doesn't mater now because iv realised it does it automatically

so whats the difference between the complex and the simple mesh other than ones more complex and doesn't appear to work

is there a way to make the collision super accurate to the visuals @grim ore

[fading cobalt]

hey guys, is there any way to avoid a huge memory leak while importing an alembic file?

[true leaf]

So let's say I make a house using about 1000 little actors (walls pieces floor pieces stairs etc) for my level and I want to clone that house around the map. What's the best way to do that

Seems like grouping the actors is not .. ideal. Maybe converting to a static mesh w collision ??

Is that the 'right way'?

[pallid compass]

You could use a BP actor as a wrapper for it

Design the house in bp

little overhead

But easy af

[plush yew]

Had an idea for a game. What about a game where you play as a super hero. My idea is, you have your secret hideout to yourself, but when you decide to leave, you’re thrown into a massive world full of villains and heroes. You can find NPCs which will give you missions to increase your strength and unlock new abilities. In your hideout, you can also participate in “simulations” which throws you yin to another map where you can fight against other players

Just a random idea I had.

where i can download visual basic c++ tools ?
i need to build a project

[pallid compass]

The instructions are on ue4 github repo

[lofty hollow]

Unreal closes down when i stop debugging in visual studio, anyone knows how to fix this?

[north shale]

@grim ore ok i did a line trace to the ground and it works except the line trace is parallel with world Z not my players Z do you or anyone else know how to fix it

[frosty copper]

🤔 something along the lines of local vs world stuffs

[abstract relic]

I saw. My apologies 😜

[north shale]

NP 😄

[static viper]

you cann that a line trace to the ground?

you know you can just sorta... world location z - 10000

as end

and world location z as start

XD

[north shale]

what do you mean

im not quite following

[static viper]

up vector

why do you need that

[pallid compass]

Don't click stop

Click detach

[north shale]

because the up vector is the position im trying to work the line trace off i.e. i get the up *-1 to get the invers and set that as the direction the line trace will be in

[fierce tulip]

or you know, read the rules

[north shale]

does anyone know how i can create a Collison mesh = to the object not like the green in the image more like the actual visible mesh https://imgur.com/a/oREGe43

[fierce tulip]

either make it yourself, try that collision generator inside the mesh viewer, or if it needs to be 100% accurate but most costly, set the collision to "use complex as simple"

[north shale]

ok i figured it out all i had to do was change this https://imgur.com/a/5LYQYnZ

[placid arrow]

Is there a place where I can find information on how to create a tutorial level in my game? I've already created one without needing to refer to any other source and want to compare what I've done to how others do it

The problem is searching for "how do I add a tutorial level to my game" or any similar query just brings back a million and a half results of "unity tutorial for how to create a game". Google really does not understand this concept...

If I adjust the query to remove any results including "unity" and only show those including "unreal" I really get little of relevance still.

[whole quarry]

is there even a standard way of making a tutorial level?

[dry moon]

uhh not really

people like less intrusive tutorials though

instead of holding hands throughout the whole way

[whole quarry]

Dark Souls 3 has one of the best tutorial levels

[dry moon]

just a pop up "hey you can do this' and let people do what they wish with the info

[whole quarry]

and it doesnt tell you anything

thats best indeed

and maybe some clever level design for the first few levels

[grim ore]

maybe someone here has an idea. I want to somehow use UMG in a parent/child relationship. I want a master UMG that has data I can set (parent) and have maybe 10 children that are all identical just differing in the data (children). The problem is they are not all the same "class" so I can't just reference them all the same when trying to process data on them 😦 any ideas?

[pallid compass]

Interface

[grim ore]

how would that work?

[pallid compass]

If your struggling to just reference them, or / and keep track of alot of mixed references

Then ref too there interface pointer should do it

Interface with a base set amount of functionality all the classes will have to process the data

Assuming you can get a classes interface ref in bp

[grim ore]

say I have 10 UMG widgets and I want to add 3 of them to the screen. Unless I hard reference widget1, widget2, widget3, etc. I can't generically reference them as say widget

[pallid compass]

What do you mean by add

Add to viewport?

[grim ore]

Master widget, it has a panel. I want to add a couple widgets to the panel. The widgets are say CoolWidget1, CoolWidget2, CoolWidget3, etc.

meh... I think it's just the issue with child/parent

[pallid compass]

I am not 100% following your problem

If you know what widgets you want too add

[grim ore]

yeah its complicated lol

[pallid compass]

Then i dont see the problem

[grim ore]

yeah lemme explain it better. 1 master widget, a playbook. It holds a scroll panel that is supposed to show plays. The plays are all widgets that visually represent data.

the first issue is I can't make a master "play" widget and then make children from it that all inherit from the parent

where the children just have differing data

[north shale]

is there a way to have complex collisions on and physics?

[pallid compass]

let me reword that

phone went full potato

Why does your playbook and play widgets have to be related

[grim ore]

they don't, the playbook just holds the plays

the plays should be designed visually in UMG and are just different representations of data

but I completely forgot I can use new blueprint and subclass a widget...

[pallid compass]

No matter what the class there sholdnt be any problem at all

just reference it as a UWidget

or UUserWidget

The same way you can pass around UObjects

[spiral island]

I think he wants to have a single generic widget which can hold data representing something, but he wants to be able to create them or reference them dynamically

[grim ore]

yeah It's a confusing mess, I forgot about just pure subclassing widgets as it's not the normal workflow for them

[pallid compass]

Well if thats the case just have a data struct and a base class with a function you can override to drive the widget data display

[spiral island]

if you're willing to use C++, then the solution should be much more trivial

[pallid compass]

It shouldnt even matter RAV

[grim ore]

yeah the data struct was the next idea but then you can't visually set up the system you have to data drive it

[pallid compass]

wat

I am so confused man

This is making no sense

What is the data

[grim ore]

2d vector data

[spiral island]

are you making a replay browser?

[grim ore]

https://i.imgur.com/cytJ22P.png

[pallid compass]

You need to display FVector2D?

[grim ore]

each icon is data I want to be able to pull out later, it's position

so I am visually displaying the data as you can see here and later I want to get access to that data thru the widget

[pallid compass]

Still confused as fuck, try again
Give some solid details

[grim ore]

I've given all the details lol

thats a widget, it has some images and those images have positions in the widget.

[spiral island]

maybe you can make a class which has pointers to all the onscreen objects, and then can generate the widget as needed?

[pallid compass]

Thats better, keep going

[grim ore]

I want to make say 10 of these widgets all with different positions on those images

now say I want player 1 to only have access to 3 out of the 10

[pallid compass]

You want 10 of them Widgets that had little image widgets inside of them correct?

[grim ore]

I want 10 of what you can see in the picture

the only different is the images, the little blue/green/yellow icons, will all be in different places

if I wanted to do it in just data then it's an array of V2D and its no issue but I want to visually store this data in the widget basically

[pallid compass]

So yes then

[dark depot]

might be better to just use 1 widget that you create then set the images

[grim ore]

yes that was the other option but then you visually can't set the images at design time

[pallid compass]

TArray<TArray<FVector2D>>>

An array of arrays of pos

or you can even use a struct wrapper for it

to include extra info

[dark depot]

should work in Preconstruct right?

or whatever its called

[grim ore]

how would I define the positions, like where?

I could make a data table with the positions and feed it in sure but then that data is in a data form and not visual when editing/setting up

[pallid compass]

no data table very bad, dont do that

Okay so the first question is, ignoring everything else

How are you going to keep track of 5 green, 5 blue, 1 yellow

[grim ore]

visually lol

[pallid compass]

No you need away to store the actual data

[grim ore]

and internally in the widget they are in an array

[pallid compass]

Putting it all in 1 array would get confusing

[grim ore]

nope it's 12 icons 0-12

[spiral island]

would an array of structs work for you?

[grim ore]

It's literally simple the problem is I am trying to figure out how to make it more dynamic instead of fixed and it's stuck

[pallid compass]

maybe im dumb af but this seams trivial to make flexible

[spiral island]

add / remove from array

and then redraw the widgets to reflect the array

[grim ore]

yep the problem is having to not keep a hold of it as "widget1" which is of type "widget1" and "widget2" which is of type "widget2"

[spiral island]

that's what arrays are for
unless there's some part of your situation that I'm not understanding

[pallid compass]

Display Widget
Display Widget Struct
TArray<what ever these things are>
TArray<FVector2D> Mirrored to above array
SomeDataType Reference to me
SomeWidgetRef Reference to my owner/creator

[grim ore]

but each widget would be it's own unique thing and I don't think I can get around that if I want to do it visually.

unless I can make some sort of data object to just hold data and then visually make up that data object in a separate thing =/

[spiral island]

what are all the things you need to store?

[grim ore]

just positions, vector2d but I want to be able to visually set it up

[pallid compass]

What do you mean own unique thing

[grim ore]

not just "oh look here is a struct with some data in it"

[spiral island]

and the best thing I think is to store the data in one place, and then have a separate system which can visually represent the data

[pallid compass]

THey would be instanced, why would that matter

Its not static data

you keep a Array ref too all the play things you make, then the play things contain that stuff i posted above

[grim ore]

ok let's try this. Say I wanted to have 2 widgets on the screen

each widget holds 1 image

each image is different.

this would require 2 widgets that are unique unless you created them at runtime and passed in the unique image right?

[spiral island]

not necessarily

you'd have a property for the image

[pallid compass]

Nope, you just pass the image u want for it during a constructor or some way to init

Because obviously, you need to know what images you want

If u want it at design time

[grim ore]

... I said unless you created them at runtime... that would be using the constructor or init

[spiral island]

as long as you design it as a flexible generic class, then you should be able to do it at runtime or design time

[pallid compass]

You can expose a property that you can set an image ref too, and have it populate at run time from that, similar too data blueprints

[grim ore]

but visually was the key 😦

[pallid compass]

You can have it populate visually in design time

1 sec

let me boot my engine up

You want this stuff at editor design time right?

[grim ore]

I think I am overthinking how to do it is the issue

[spiral island]

is there a reason you want to do this at design time visually?

because it seems harder

[grim ore]

I would still need a ref to all of the individual layouts somewhere so using that to populate unique widgets would be fine

[pallid compass]

nah its good reason to do it at design time

Why dont you use data assets then

If u want that

[grim ore]

if you look at that image it's a layout of stuff, doing it at runtime or in code or with data means you still need to visually figure out what goes where but then you just convert it to the data separately

yeah I think I am overthinking it is the issue, maybe trying to abstract it down to a layer that is just not doable

something somewhere has to keep track of "this widget = this class" or something similar so you can keep track of what player knows what from that list for example.

so I still need to create a master list of the plays somewhere, I think forgetting that I can manually subclass a widget is what caused my tangent lol

[pallid compass]

wat "this widget = this class"

u dont need to track that

you should know or u can even get the engine too tell u

what class something is

[grim ore]

say I have a list of 10 plays, 10 widgets.

and I want the player to know they should show 3 of them when the playbook is on the screen.

[pallid compass]

10 plays 10 widgets what

10 Players?

[spiral island]

store in the struct a hashset of which players can access the data

[pallid compass]

He cant

Stuff like that wont replicate

TMaps and shit dont replicate

[spiral island]

rip

[pallid compass]

Mirroring arrays can slove that problem though, or mirror lists

But that is unrelated

[grim ore]

https://i.imgur.com/d9CMvKa.jpg

say you have that as your "playbook" and there are 4 "plays" you are showing

[pallid compass]

Yup i follow

[grim ore]

you have a potential of 10 plays total that "could" be shown

the player has unlocked 4 of them

each "play" is a separate widget that contains the data for the play that the designer set up

[pallid compass]

Yeah

[grim ore]

so internally the player has to store something that knows what they have unlocked. Either a simple list of values that are mapped to something that shows which class to spawn in

or something else.

[pallid compass]

Well you would not separate the different plays in too different classes

Your just loading some sort of data set in too a Generic display widget

[grim ore]

....which

is the problem we keep getting back to lol

[pallid compass]

These data sets would have some sort of reference

ID, FGamePlayTag, FName, what ever u want really

[grim ore]

doing this without data driving the display but the display driving the data

[pallid compass]

Displays should never drive Data

[grim ore]

each widget has positional data already in it that can be used for data purposes, the position

requiring a designer to layout a visual representation of data without doing it visually is just not right

[pallid compass]

Your Data should be driving your displays period, how you create that data is another story.

Your asking for away to serialise the data in from some sort of design system right?

[grim ore]

well I don't have to if I just use the widget itself, it has all the data in it.

[north shale]

is there a way to push or pull an object with physics disabled?

[grim ore]

@north shale you can just change the location of the item when you touch it to simulate that effect

[pallid compass]

Yeah you can do that, but that is super bad practice imo

But u can just yolo fuck it

and subclass a base one

Set it up

then give it a FName or tag

or some way to track it

or u can class track, but then u will struggle if more than 1 of the same class

But yeah this is what i mean

[grim ore]

yeah I think I got it now. I never said this was smart but I am trying to work around limitations of the editor tools we have access to now in UE4. Once we get the new editor utility widget I think this would be a ton easier

[pallid compass]

system is flawed already doing it that way,

Im actually about to make a pullrequest

That would let u do this

for UMG customization

[grim ore]

it's super simple in Unity, just realizing how much more annoying stuff like this is in pure BP in UE4 right now without being able to do editor utilities easily

[pallid compass]

But no idea when it will be in, or if epic will accept

[north shale]

ok what im wanting is for my character to be drawn to an object but i cant use Add force or add impulse because if i have physics on the player cant walk he just hovers

[pallid compass]

Yeah the editor is complex, thats why its hard to do

But its complex for alot of good reasons

[grim ore]

well 4.22 should have the editor utility widget which will let you design editor utilities using UMG, works quite nicely.

[pallid compass]

jfc that sounds gross af lmao

[grim ore]

https://answers.unrealengine.com/questions/551645/pull-character-zone.html might help

this is basically getting the location of the item this code is on, finding the player, figuring out the direction from the player to the item, and adding input on the player to push it towards the item

@pallid compass thanks for the help btw. I never thought this was a good idea just an idea I was trying to do 😃 The chat helped me remember I could subclass directly so it was helpful.

[pallid compass]

There is actually a ton of dodgy ways to do what u want

But i wouldnt recommend it

I do it all the time for my UMG splines plugin

lmao

Dodgy designer stuff

[grim ore]

yep yep. It was a silly project idea for the superbowl, designing plays in UMG and having a display you can click on then having the characters on the field below moving to that position. Just to show off stuff like event dispatchers and some basic AI and interaction between UMG and other objects thru BP communication. I kinda got fixated on making it super dynamic and robust rather than just working lol

[pallid compass]

Really need a custom data type and data editor window for it tbhg

[grim ore]

yep I agree which is what I was trying to use the UMG editor for lol

I am so used to full file and data access in Unity

[spiral island]

is there a way to force the engine to drop frames?
on my tower PC my game runs at 120fps, but on my laptop it runs at about 40
this is fine, except that instead of dropping frames on my laptop, the game just runs more slowly

everything moves more slowly

[grim ore]

drop frames or run at a lower frame rate?

[spiral island]

I want the events to happen at the same speed, and drop frames to keep up

[grim ore]

t.maxfps XX in the console where XX is your max Frame Rate limits the frames

you can adjust that in the project settings as well

you might be having actual bottlenecks or hiccups and I have no idea how to simulate that

[spiral island]

I'd record it but my laptop is so slow that recording the screen would make it look like it's doing the right thing lmao

[pallid compass]

If your dropping frames and shit is running slowly

Your game is 100% setup wrong

Sounds like your doing stuff on tick

and not compensating with delta time

[spiral island]

is there a different event than tick I should be using?

[celest creek]

Hello all - I'm looking for a way to have a ship rotate around its own axis no matter what way its facing. Seems very simple but I'm missing something I'm sure..

I've explained it (hopefully) well here: https://forums.unrealengine.com/development-discussion/blueprint-visual-scripting/1563525-ship-rotating-around-its-own-axis-project-download-included

@celest creek how do you rotate it now?

[celest creek]

I just tick up rotation values per axis

maybe a naive 'solution'

a project is available to download to show it better but that's it

[pallid compass]

@spiral island Its not reallt to do with Tick, the problem is tick fires every frame, so more frames = more ticks

So you need to compensate for this

[spiral island]

ok

[pallid compass]

This is what the float variable that comes off it is for

Delta time

[spiral island]

so I would use this to scale the amount that my stuff moves

but what about things that I don't control directly, like a physics object where I set the initial velocity?

[pallid compass]

Prob wouldnt be setting velocity on tick

[spiral island]

I set it when its fired, but it still seems to move tied to the frame rate

so even if I scaled my control speeds, the projectiles would still move more slowly

[pallid compass]

can u show me

that does not sound right at all

[spiral island]

one sec

ok i forced it on fixed framerate and it seems to work
but when I use smoothed frame rate it runs slower

[pallid compass]

Yeah thats still a massive problem

if u plan to give it to anyone else

[spiral island]

I'll update my movement logic first and then see if I missed something in my projectile

[north shale]

is there a reason why the player cant walk when you enable physics?

[pallid compass]

because your trying to drive them with physics?

[north shale]

how does the gravity work without physics can i change its direction?

[pallid compass]

Not in bp afaik

Might be wrong though

[north shale]

afaik?

[pallid compass]

as far as i know

[north shale]

kk

thats a pain i really need to have it changeable

im trying to make a character who walks on a planet

[pallid compass]

Yeah that sounds like c++ stuff

[spiral island]

this is what I mean
I'm recreating the unity tanks sample in ue4

https://streamable.com/xul2b
https://streamable.com/i6j9n

in the 20fps recording, the bullet seems to take longer to get to its destination
ignore the fact that the tanks themselves move more slowly I haven't put the deltatime scaling in yet

[grim ore]

yeah it all seems to be running on tick or on axis for movement so it's fps limited, your not really taking into account the frame rate on the input

[spiral island]

i know that for the tanks
but why is the bullet moving more slowly

I left that up to the physics engine

[grim ore]

what's the actual code for your bullet?

[spiral island]

its got basically no code
a tank gives it an inital velocity, which it just hands off to ProjectileMovement's initial velocity when it is created

then the bullet has no code running except on BeginOverlap, where it spawns an explosion and destroys itself

[north shale]

is it posable to do a few things with C++ and the rest with blueprint?

[spiral island]

you can call events to / from C++ and blueprint

[north shale]

is it worth learning C++ i only know a bit about C#

[spiral island]

yes

[pallid compass]

You need to learn general c++ before u touch ue4 c++

I like this one myself, worth the money imo

[north shale]

kk thanks

[gilded plinth]

Any ideas why my skeletal mesh decided to stop casting shadows in some places?

so confused : P I recently triangulated in maya and re-imported, but not much else

I'd post the avatar, but the bot blocked it i guess cause it's a naked avatar : / tried a new basic opaque material, but still a no go

appears to have something to do with the physics asset : / wtf

if i remove it, i get better shadows

ah answer is that unfortunately i have to re-create my physics assets after skeletal mesh re-import cause the physics bounds were off

[native cradle]

Just curious

Do we need to install Unreal engine on the mac we want to use for remote building ipa from windows machine?

I have done this in the mast mindlessly. It really came up just as I was about to set up a diff mac machine

[regal mulch]

What's the practice if you have different SkeletalMeshes with different AnimBPs that technically all need to do the same thing (and have the same named bone affected by it)?

They all have the same "basic" bones, but each of the meshes might add some extra bones for some unique parts of it.

Don't want to copy paste code 10+times

[weary void]

Hello ! I don't know in which channel in should ask this

I hope this one will be the right one

I've been working on a video game for the past 3 years

I today I wrote a publishing document using google slides

I wrote it in english in a matter of comprehension for every one I could send it to

However, I'm french

which means, my english is very baguette pain fromage

the document is checked and complete, but I would still need someone to help me fix the wrong sentences

could anyone please help me ?

There is ~10 slides like this one which need to be checked 😊

[plush yew]

hey, how to load object in runtime? I tried to use StaticLoadObject, but failed, it always return nullptr

[regal mulch]

@weary void That would technically also fit into #looking-for-talent

[weary void]

yup

want me to move it away ?

[polar hawk]

@regal mulch I know someone is trying to do this with anim subinstances and stuff

but

going through all that shit

it caused some problems and they switched back to 2 anim bps

<_<

There is a smart way to do it, but

¯_(ツ)_/¯

[regal mulch]

Yeah if it would be 2 BPs I would just not care.

But we have a handful, one for each weapon.

Might just find a way to modify it from within the WeaponBP instead of AnimBP

[light bobcat]

why you bully me

[bronze cedar]

why there is a spot , that light spot

i am using directional light, and making this light like on the top,so that i get shadows but not that much long , but than this aura or light area is coming, i understand why it's coming, but is there a way to make it invisible

when changing the angle of the light, that spot go away but i get some bad shadows what i don't want, i want shadows but very little

[static viper]

thats no spotlight

its the materials roughness

[wary wave]

could be specularity, but tbh it does look like a pointlight

[static viper]

well he said angle

so it must be a highlight

[bronze cedar]

it's a directional light, yeah might be a material problem, like reflection , but how to get right from that

[wary wave]

change material roughness values

[bronze cedar]

oh ok , thanks for the help guys 😄 😃

OMG it's go went and gone, haha thanks guys @wary wave and @static viper

[polar hawk]

@regal mulch I wonder if you could like

procedurally generate an anim graph

right

like oh man

[regal mulch]

It feels like it's the same shite as with UMG Inheritance

You kinda could just inherit from a parent class, but then feature XY breaks it

[polar hawk]

yeah

object oriented my ass

[wary wave]

hahaha

[merry gazelle]

I've noticed that linetrace seems to bias towards (0,0,0,0), can anyone explain to me why this is the case?

In my example, the arrow(start of trace) is pointing directly down. In spite this, most of the line traces seem to generate towards the middle of the map

[digital anchor]

well because end is a world position

and 500 randomly from the center of the world, is still near the center of the world

[merry gazelle]

can I convert end to a relative position?

[digital anchor]

yep, just End + Arrow.GetWorldLocation

[merry gazelle]

ok cool got it, so are all vector pins by default world location

[digital anchor]

humm.. they are a location but what kind depends on the context

if you add to a actor location, they are relative to that actor, if you subtract that actor they are back in world position

[merry gazelle]

ok thanks 😅

[mental salmon]

Help, My shader is not compiled for GLS_ES2, no error, nothing, it's just not there 😦

[fierce tulip]

you enabled es2 preview in the shader?

[mental salmon]

It's not an Editor shader, it's a usf file. Pretty basic

#include "/Engine/Private/Common.ush"

void MainVS(
    float2 InPosition : ATTRIBUTE0,
    float2 InUV       : ATTRIBUTE1,
    out FScreenVertexOutput Output
)
{
    DrawRectangle( float4( InPosition, 0, 1 ), InUV, Output.Position, Output.UV);
}

float4 MyColor;
#if (COMPILER_GLSL_ES2 || COMPILER_GLSL_ES3_1)
    TextureExternal InTexture;
#else
    Texture2D InTexture;
#endif
SamplerState InTextureSampler;


void MainPS(
    FScreenVertexOutput Input,
    out float4 OutColor : SV_Target0
    )
{
    OutColor = Texture2DSample(InTexture, InTextureSampler, Input.UV);
    OutColor.r = OutColor.r + MyColor.r;
}

If i set r.ShaderDevelopmentMode to 1, and run in vulkan mode, i see my shader compiled in Saved/ShaderDebugInfo/VulkanSomething, but i want to run it on android

[north shale]

does anyone know how i can set an actor to calculate complex over simple collision every tick in BP? ik how to get the character to do it if its walking but i want other actors to have it

[merry gazelle]

Anyone know of a reason why this black plane "substrate" component is seemingly being hit, yet the "oncompnenthit" doesn't trigger anything

[grim ore]

on component hit in the bp where the black thing is? if so a line trace is not physics it's not going to trigger a physics hit, you need a collider for that

[digital anchor]

alternatively, do your stuff after the line trace result, instead of OnComponentHit

[merry gazelle]

the line trace is fired from a child actor and the parent actor has the plane I want to hit

I'll take a look

[grim ore]

yep the line trace is just a line trace, a representation of a thingy checking for colliding layers but not using physics so no physics interactions (overlap/hit)

this is a good use for a blueprint interface, after you hit with the trace you just tell the object you hit that you hit it and trigger an interface event on the thing you hit to do whatever.

[merry gazelle]

I was watching one of your tutorials that involved using BP interface with linetraces but I can't remember what it was called 😅

[grim ore]

well I won't remember either so I am no help lol

[merry gazelle]

it's cool I'll find it

MVP FPS #5 - Setup Our Hit Event ( UE4 ) this one

[grim ore]

yeah I was going to say it's probably in the FPS one. I dunno what's actually in the interface one lol shrug

[earnest cape]

So I know that currently the only way to access these variables is if you are using a C++ project, but it would be great to have them exposed to blueprints

[grim ore]

vote for it on the answerhub as a request?

[north shale]

how do i get the actor to use the complex over the simple collision?https://imgur.com/a/YAU3HGb

[merry gazelle]

got imy HIT stuff working now 😄

[vale silo]

someone needs to make a plugin for split screen multiplayer for the Marketplace 😉

[plush yew]

Hello everyone! I am brand new to this server. I have been working on a particular part of a game I am developing in UE4 for the past 4 days or so. I made lots of progress, but am currently stuck on a specific part. Been trying to figure out for the past 5 hours. Could anyone please help me?

[cloud cobalt]

Ask your questions

[grim ore]

Restart the PC, it will probably fix the problem. If not it's a good time to make some tea and reflect on the problem away from the PC.

[plush yew]

Would anyone be willing to hop in the voice chat with me and try to help me?

[cloud cobalt]

Just explain what's going wrong, what you're trying to do etc

[plush yew]

Ok... so I have been trying to add a flying animation to my character

I have retargeted the animations from the animation set i wanted to use, and now I have the animations and the blend space

[grim ore]

maybe we can convince Epic to hire someone to just expose every missing BP feature as their primary job 😃 that would be so nifty.

[plush yew]

when I apply the blend space to my animate graphic, and created the proper event graph with the right variable, and then added the function of button "F" to start the flying, everything works right besides the fact that the space blend animation for flying is not triggering !

it flies with the walking animation.

[north shale]

ya that would be so good @grim ore

[plush yew]

I never used UE4 before last week, and have worked in it for about 70 hours already

if anyone could help me with this, I could even live screen share and show you what I did.

[grim ore]

so how are you checking to see if it is flying?

[plush yew]

I pressed the play button, pressed my assigned key of F and it is going in the air

and it is moving with the camera as my direction as I set it as such

so the flying is proper

[plush marsh]

there is a plugin for a proper flying

[plush yew]

I am in the GENERAL tab for voice chat if anyone could hop in and help me

would be easier to explain it via voice

[plush marsh]

without it , or custom code, flying is not supported properly iirc

[grim ore]

ok so that's how you are making him fly, but how are you checking to see if they are flying. You said you created the proper graph with the right variable.

[plush yew]

mathew one moment, a is helping me

[plush marsh]

Nope, I'm bad at animation

So, the issue is that animation is not switching for a proper one when char is flying.

As i understand there is a bool var to check if char is flying

[plush yew]

Yeah I have it set

[grim ore]

where are you setting it and how are you checking to see if they are flying in the anim bp?

[plush yew]

I am not sure what that means Mathew

If anyone could hop on a voice chat with me and try to help me, I will forever be greatful to you. I will even give you credits in my game!

[grim ore]

well the anim bp determines what your animations do, somewhere you have to tell the anim bp that you are flying so it can use the flying animations. where are you checking to see if it flying

[plush yew]

Let me check quickly.

[earnest cape]

@grim ore https://answers.unrealengine.com/questions/871472/expose-use-split-screen-variable.html

[grim ore]

yep I was reading that and it's still a missing default node 😦

[plush yew]

Mathew, where would I go to tell my animation bp that I am flying?

[earnest cape]

D:

[wary wave]

seems weird Epic would do a split screen category when you can't properly do split screen in BP 🤔

[grim ore]

usually in the main graph when it is getting variables like speed you would set a is flying variable or something like that so you can then later check that as part of your state machine

so epic needs to fix splitscreen in BP first! I had no idea it didn't work that's.... weird isnt it?'

[earnest cape]

Yeah it seems like that should have been exposed a long time ago

[plush yew]

Mathew, is there any way you can hop on a call with me for 5 minutes

I think you are on the right track of what is wrong here.

[grim ore]

I am at work so nope

[plush yew]

ah dang

am I allowed to send screenshots here in this chat>

[grim ore]

the basic animation tutorials on the docs pages walk thru how it works

[earnest cape]

At least I can do a lot of things with local multiplayer right now, just not that lol

@plush yew yes

[plush yew]

so this is my flying bp - called "travel_bp

and my ThirdPersonAnimation has this anime graph created

the travel bs there is the flying animation

and from there...

i made the variable is flying?

[grim ore]

and you set that where?

[plush yew]

and assigned to true and not treu

[grim ore]

where do you go "IsFlying = true" in your flow

[plush yew]

and then coded this into my player character

ill show you

[grim ore]

and if you say on the character then.... lol

[grim ore]

the character != anim blueprint

[plush yew]

in third person animation bp

i have this line

and "is flying?" connects to the speed

when I play test it

and press F

[grim ore]

ok then I take it back you are doing that right atleast

[plush yew]

everything seems to work perfect

besides 1 thing

the flying animation is not playing on pressing F

it just keeps walking

[grim ore]

when you hit F do you change the movement mode on the character to flying?

[plush yew]

but it does get off the ground and goes about any direction iw ant

how can I check that?

I have only been using ue4 for 1 week

so I am super new
