It seems to be if I do a screenshot its fine, if I do supersampling / 360 so anything where ansel has to process, it ruins the image

[covert hedge]

@sinful bone i dont think you can promote things to variables in materials no. I might be rwong tho

[sinful bone]

@covert hedge I see thanks. I used a material function for now

My team gave me this mesh, which seems to come with a collision plane in it. I wanted to exchange the mesh to increase the vertices, but my mesh is now missing this information and the player falls through the ground. How do I add this information to my mesh?

Mine just says 0 and I can't seem to add it in the editor here.

Ah, there's a dropdown menu to add collision. Nevermind 🙂

[rose quartz]

I want to check my map with Play from here but some how the player always go to x=0, y=0 and i dont have player start or pawn or something on my map

hmmm

guys i am packaging a game in unreal engine 4 and its taking to long can some one help i can stream and show

[storm vapor]

Hey i packaged my game

But i want to change the name

How can i do ? It packaged with my project name for example if my project name was "A", then packaged like a.exe

Is there a way to change ?

please help

[rose quartz]

Damn why it always happen when im trying to move a forlder or rename it the liks are gone in blueprints

[versed spear]

Everyone jump on the Paper3D hype train! Ride it till release!

Anyone else excited about bringing 2D into 3D worlds. You don't see to much of that around here. https://youtu.be/z3fj-VNZfOI

[sinful bone]

Anybody know how I can get the CollisionWorldPosition in a niagara module? The dropdown doesn't find this?

Am I missing some kind of setting or something?

[rough knoll]

what did i do wrong here?

success should be "set" here, but it still goes as not set

[sturdy trench]

My friend got a plugin from marketplace and we've used it for a freelance job before, I still have the plugin located on my HDD, can I use it on my own project?

Without any problems with author of plugin and Epic lol

Plugin does not exists on my account I just have the plugins folder

[versed spear]

Well there is no issue in using it. Possession is 9/10ths the law j/k but I would use it and when I go to release anything I would pay for it.

I am sure if something was released and the developer was that hard up for cash there would be ways to prove that A you do not own that plugin on your any account related to the game you released and B it would be easy to look at assembly and see that you are using the plugin by searching regexe matches

[supple totem]

@marble pollen you might have more luck with Insights if stat isn't helping

[regal hollow]

quick question guys

can i split an object texture into RGB? so if I use a packed texture i only have one output but can I break that output/

[surreal laurel]

@regal hollow I think you're looking for the component mask node

[regal hollow]

thanks man ❤️

[digital anchor]

just clarifying, a texture object is a reference to a texture, its not yet sampled, so colors dont exist yet

[regal hollow]

but if you pack a texture you should be able to output it correct?

[digital anchor]

once you sample it with a texture sampler yes

[regal hollow]

but texture samplers can't work with world aligned textures, it needs to be a 2d texture object/

[digital anchor]

because the function samples it many times inside, not once

check if the function asks for which channel to sample, then you can choose which channel you want
else you would need to modify the function if you want a different behavior

[slender moss]

why is my mesh exporting on the wrong z axis in ue4 (from blender) but all other meshes are fine??

[digital anchor]

but you can just split after the function, if it returns all channels

[abstract plank]

@rough knoll looks like you're trying to set a boolean value but the boolean your setting isn't plugged in so it's not setting anything

Your boolean should be a red node, plug it into that empty node on your script and it should start working fine

[digital anchor]

@slender moss you mean wrong yaw? i always export with -90 yaw as blender is +Y front and UE4 is +X front

[slender moss]

if i go into edit mode the mesh rotates 180 degrees? how do i correct? I tried applying rotation but didnt work

it is rotated 180 degrees in ue4 so it must be something to do with that

[sturdy trench]

@versed spear so Epic checks the regex for plugins?

[sturdy trench]

so the problem is this, we brought the plugin together, but used the card on his acc. due country-restriction issues..

[slender moss]

how to correct?

[plush yew]

how can i make collision ? my character just to true the mesh haha xD

[serene birch]

as long as your uproject doesn't use the plugin it should be perfectly fine

[marble pollen]

@supple totem I think that's for 4.25 only, I'm using 4.20 at the moment. =/

[supple totem]

ah hm

maybe post screens of the stat window? screenshot the most expensive part

[lusty carbon]

Hi! Baking lighting in my scene results in UE4 freezing for a very long time after finished the bake

which results in having to end the process and crash unreal

what could be the reason for that?

[sturdy trench]

have you look into output log while building? might give an idea

also crash log can give idea too

[plush yew]

uhuum 😄

please help me 😄 :p

first screenshot you see ❤️

[drifting geode]

hew folks, have three products (actors with severel static mesh components) and i would like cycle thorugh these products with a trigger...

is there an option to add all my product actors to an array cycle through it by index?

i did something like this a while ago, but back then i had just several static meshes (each one a different product)

[lusty carbon]

have you look into output log while building? might give an idea
@sturdy trench I'll try.

also crash log can give idea too
@sturdy trench no crash log cause it won't crash just freeze. I then end the task actively to crash it

[plush yew]

is there a site which sorts all unreal engine videos?

for loop... if i understand correctly @drifting geode

[plush yew]

dont wanna scroll thru twitch

[drifting geode]

@sturdy trenchyes but how can i add my actors to an array?

[sturdy trench]

first you need to get them through reference

"get all actors of class" .. or by overlapping, or hit result

depens on the gameplay

then you create an "Actor" array, which can contain any type of array

then you can do a for loop from get all actors of class or directly add from other options not sure which one you gonna use

add the actors to your actor array

[drifting geode]

it doesn't let me add actors

[sturdy trench]

well not that way

[plush yew]

thanks

[drifting geode]

if i chose static mesh array, i can pick from the content browser

[plush yew]

got it i had to set collision

[sturdy trench]

you wanna choose from content browser? sorry if i missed that part 😅

[drifting geode]

sorry, forgot to mention that 🙂

[sturdy trench]

as far as i know, you can only choose classes from content browser

not objects

actors are objects

classes are different.. not spawned on level, they point something on memory --- "as far as i know"

take these things with grain of salt

[drifting geode]

oh!

[sturdy trench]

you might wanna ask in #blueprint about choosing objects/actors from content browser

but normally, to spawn or manipulate actors first you need to spawn them or somehow refer them

then you can access them

if this is for spawning actors or for similiar action, classes are good to go

but if its a gameplay action or about changing variables inside actor etc. etc. you shouldnt use classes in this case

[gleaming agate]

anyone know how to call other files from a {Plugin}.Target.cs file?

[spice canopy]

Hey when I create a shipping build, I can't find the Save folder. I need to remove the Save game before I submit my app to the store so it starts in a clean, unused state without any of the settings changed.

Ah, quick google search gave an answer. I'm surprised. Usually I can't find stuff about Unreal just by googling:
A game packaged in Shipping configuration saves its stuff to C:\Users\UserName\AppData\Local\GameName

Well I guess that means my save data won't carry over into the package I publish anyway. Neat 🙂 No need to delete

[lusty carbon]

Help! stuck like this forever after bake

[fading hull]

Since I'm a complete newbie in UE4, then I'm gonna ask, what is better for making games in Uneral Engine, C++ or Blueprints

[wanton lotus]

@drifting geode this is fairly easy to accomplish. First you need to make sure your actor array can easily be referenced, so put it somewhere globally accessible like game instance, player controller, game mode, etc. Then you can edit your actor blueprint and have it add itself to that array on construct.

This will work if all the actors are spawned in the same world. If not, you make an array of classes so you can spawn the actors as needed.

@fading hull when used correctly, C++ will be more efficient. However, both are just as bad if used wrong. For instance, a function coded in C++ could be less efficient than using a blueprint alternative if the C++ code was written inefficiently. To sum it all up, only use C++ if you are well versed in programming, otherwise stick to blueprints.

[fading hull]

Alright, thank you for the advice! 🙂

[plush yew]

i float on the mesh 🙂

dam thats not good xD

so how can i fix it ? 🙂

the first 2 screen is 1 actor

I have a question, what is the point of using pointers, isnt easier to just use normal variables?

[supple crag]

Ok nvm the nvm. I just made a workaround by using a size box and estimating the width. It works but if there is a way to make this without a sizebox i would be glad to hear about it 😄

[abstract plank]

@boreal mauve your lighting resolution is too low

In your editor click the button that's set to "lit" by default, click optimization view modes, click light map density. Then click the door and change its density

In the details of the object that will be under lighting, the static lighting resolution value is what you are looking for

[inner cloak]

Is there anyone that could help me with building the engine manually ... on an older version of UE4 ?

[grim ore]

it should compile out of the box if you are using the correct version of the tools

[wanton lotus]

@inner cloak An easy to follow guide is contained within the readme file of the repository. I literally just got done following it with no problems. All to just expose a single function, haha.

[rich furnace]

can I use pixel streaming to output the contents of a media texture (dynamic animation) to the cloud

[inner cloak]

@wanton lotus thing is, i need to setup 4.20

Is this the version you installed?

[grim ore]

we know you want .20, do you have the correct tools installed for it?

[wanton lotus]

@inner cloak so you just pull from the 4.20 branch then, all the other versions are there.

[grim ore]

Visual Studio: Visual Studio 2017 v15.6.3 toolchain (14.13.26128) and Windows 10 SDK (10.0.12699.0)```

this is from the .20 release notes

[inner cloak]

I followed instruction from official source and still not working

[grim ore]

make sure your tools are correct first

[inner cloak]

Hmmmm let me check for the versions

vstudio i have the right one..

[wanton lotus]

Hah, I just noticed that 4.26 exposes the function I need in 4.25. I think I may just wait for the release instead of making a custom build of 4.25.

[supple totem]

hi all, my stat memory outputs way less than this example from the docs

is there a different command to show that?

thanks

[grim ore]

what does yours show?

I've got this for mine

[inner cloak]

does this look ok ?

[grim ore]

based on the requirements from the docs, no

go to the individual tools and install the versions they mention

[inner cloak]

can you paste me the link of the instructions ? i failed to find it

[grim ore]

its the versions I mentioned above

[rich furnace]

how can I stream a specific media texture to the internet using pixel streaming? or is there another method?

[ionic gyro]

hey guys. trying to do a fake orthographic camera by reducing FOV to a tiny number but it seems to mess up shadows. is there a fix for this? or should i not go below 5 degrees?

[wanton lotus]

@inner cloak Windows 10 SDK (10.0.12699.0) might have been referring to 10.0.16299.0 instead? I'm guessing small typo in release notes.

[supple totem]

hi matt, this is what I get

4.25

[rich furnace]

https://docs.unrealengine.com/en-US/Platforms/PixelStreaming/index.html looks like this allows broadcasting to the internet but the UE4 game instance has to run on teh cloud first? can it be local?

[grim ore]

the pixel streaming system can be run on any machine, local or internet connected depending on who you want to connect to it

[inner cloak]

Yes, i picked 16299

updating vstudio

[rich furnace]

@grim ore is it possible to stream only a specific media texture, and not the entire game screen? ex. a screen monitor

[grim ore]

@supple totem you just might not have anything using those memory groups, like mine did not show volumetric memory use

[rich furnace]

say there is a 3d object that has a media texture playing a video. I would like to stream this to the internet

[grim ore]

@rich furnace it streams the entire application

[rich furnace]

okay in that case is it possible to capture the video output of a media texture somehow

I think its beocming clear that I cannot do this

[grim ore]

out of the box i dont think you can do what you want

[ionic gyro]

so maybe i worded my question wrong. i think the real question i want to ask is what do you guys suggest is the best solution to the fact that the orthographic camera doesnt support shading? i want to do a 2.5D game but the perspective projection kind of screws up the look. especially since its an isometric game

[covert hedge]

uh does somebody remember the unreal marketplace item that would help with starting building a server/client project? I remember someone mentionning it as well as the replicated thing compendium

[inner cloak]

That is what i have so far:

[grim ore]

if you go into individual components you can see the toolchain versions and see if you have the one they recommend

[inner cloak]

just to be sure, what is the toolchain ?

[inner cloak]

i dont see those

oh wait .. you are showing for vs 2019

[fossil phoenix]

Hey folks! :)

I have a git patch that I want developers to apply to the Unreal Engine source in order to be able to develop with a plugin that I'm working on...

The problem is that this requires to build the Unreal Engine from source... which takes plenty of time, while the patch is just a few lines... Is there a better way to do this?

The git patch disables WebGL

tldr: is there a faster way to apply minimal changes to the unreal engine source without having to build for several hours?

[grim ore]

just depends on how much you change, if its a smaller change then it will just rebuild what is needed

[inner cloak]

@grim ore i dont have those MSVC build tools in my list, is this normal ?

[grim ore]

which versions does it list?

[inner cloak]

i dont see any MSVC entries

[grim ore]

do you see stuff that is 14.xx

those are the build tools

[inner cloak]

is the only place i see 14

[grim ore]

right there, vc++ toolset

14.13 is what you need

[inner cloak]

oh, so 15,6 ?

[grim ore]

Visual Studio 2017 v15.6.3 toolchain (14.13.26128)

so yes 15.6 which is 14.13

[queen mural]

hello everyone

I have a source compiled version of the UE engine, however I am confused by how marketplace plugins that want to install to engine should be used with this

In my preliminary playing with the binary launcher installed UE4 editor it was as simple as clicking install to engine to get the plugin

but now my launcher is not aware of the source compiled version and thus won't install anywhere

I could install a source version with the same (rough) version number and then manually copy over

but that seems like it would not be the right way to do this

[grim ore]

that would probably be the right way to do it

unless you have another way to get the plugins

with that said you can use the unreal version selector program to identify a folder (the source binaries folder) as a UE4 install but I dont know if that would "work" with the launcher for plugins

[queen mural]

hmm, where would this tool reside normally?

oh nevermind

I found it

interestingly that is part of both the launcher as well as my sources

thanks I think this might be it

[grim ore]

it is part of the launcher and source yep, it used to be in the binaries folder then they moved it to the launcher folder

[queen mural]

hmm

it does not seem to show up

I'll mess around a little longer but otherwise since you blessed it I'll go the semi-reasonable way of having two engine copies and manually installing plugins from one tree to the other

[grim ore]

it should work, mechanically the source and launcher versions are compatible

[open wadi]

Does anyone have a proper guide for compiling a project on MacOS? I can't find an article on it besides this medium.com article that has me git cloning the Unreal source.

Not sure if that's actually required. Where are the actual instructions for compiling an unreal project on MacOS?

[queen mural]

hmm

@grim ore I actually noticed before that it did show me the projects belonging to the source engine examples

so it already knew of the engine

it just doesn't show them

and, more importantly probably in the context of installing engine plugins; the project compatible version is said to be "Unreal Engine Other"

so I guess it just doesn't know the proper (compatible) version number for that engine

@open wadi you probbly won't need to install from source to compile a random project without explicit source dependencies. Just install the engine through the Epic launcher and then open the project from there. Once you have it open you can run it through there, it drives XCode ('s compiler) so you'll have to find the right signing settings in the project settings of the editor when that becomes a thing

[stark marsh]

help my grass only shows shaded looking at it from on side

from the other angles they're not their

[grim ore]

you cant see the other side at all? or it looks different

[stark marsh]

the shadows are not their on the other side

ill show you

this side looks finde

[open wadi]

@queen mural Oh, so I can install the Epic launcher on MacOS?

Very nice, wasn't aware.

[queen mural]

my advice would be pretty useless if it wasn't 🙂

[open wadi]

Now I have some plugins I've purchased.

[grim ore]

are you using the foliage shading model? also do you have 2 sides material on

[stark marsh]

yes

[open wadi]

But I ensured they support MacOS, I guess just download those too.

Or, if I'm copying the project from a machine that has the plugins installed, do I need to re-download them at the engine level?

I suppose so, since they're engine based.

Yeah, disregard.

[queen mural]

that depends on the plugin

[open wadi]

Right.

[queen mural]

(I believe)

[open wadi]

I mean the ones I'm using I made sure they support MacOS, so I should be good there.

Thank you for the help.

[queen mural]

No problem. UE is a beast to start up in without prior experience

[open wadi]

For sure.

[grim ore]

@stark marsh so is it the side of the material having the issue or the lighting? if you rotate the mesh does the shadow move with it (stuck to that one "side")?

[stark marsh]

it still does it

my normals are facing upwards to get the stylized look

[open wadi]

I have a question: I have a loop that is dynamically creating widgets and adding them as children to a vertical box in another parent widget. This is working, except for the fact that the widgets being created have an image with them that is potentially downloaded from a remote API.

I can use the download image node fine, but it is async, so I need to be able to first create the child widgets, then go back and reference the images within them individually as the download image operations complete.

How does one individually reference an element (such as an image or text box) within a dynamically-created child widget that has already been added as child?

[grim ore]

@stark marsh so it sounds like its your material setup then?

[stark marsh]

maybe

[grim ore]

@open wadi get the children, then get the elements from the children?

[open wadi]

@grim ore Thank you. So you're saying after a widget is created, then added as child, you can go back and get the children widgets from the parent widget again?

[grim ore]

yep, no reason why you can't. Once you add a child to a parent it's part of it's hierarchy

[peak vigil]

in 4.25 do you still need an engine from github to make a dedicated server?

[grim ore]

yes

[peak vigil]

😦

[open wadi]

Thank you much.

[open wadi]

I want to create a widget, then call a function within that widget to set up elements within it - I presume this can be done, how does one do it?

Do I need to create the widget, then cast to it, then call the function? Any time I try to do this UE4 adds a "get display name" node which seems to make it incompatible

Never mind, I got it.

like lets say it gets pushed at a 45 degree angle

but it only reads the input from one direction of the force

anyone know how to change the grass wind size? im trying to use it to make a tree sway, but the... i guess the frequency is way too small if that makes sence. I guess you can see it in the screenshot, the waves are way too small, i want them to be quite bigger than that

[dim axle]

Does Anyone know how to get rid of these logs

[open wadi]

Delete them?

I delete my logs from time to time, just delete them.

Does anyone happen to know why, when I dynamically add these widgets (via add child) to a border > scroll box > vertical box within a parent widget, they might appear greyed out like this?

You can see, the text itself is set up just like the white text you see on the left. And for some reason, a tiny little spec in the upper left corner is appearing properly.

Perhaps a z-ordering thing? I don't see where that might be set.

[pseudo star]

does anyone know what might be causing this build error or any steps i can take to find out what is causing it

[open wadi]

I just STARTED making my game and the file size is 500 MB

how do you guys shrink your game file size

[sterile tulip]

Bruh 500mb is not big

Games are 100gb nowadays

[dawn bloom]

but itch io doesn't take file sizes over 1 GB

😫

[sterile tulip]

All you can do is to delete unused assets

[arctic horizon]

1. Compressed size will be smaller
2. According to this page, using butler increases the limit to 32GB (uncompressed) https://itch.io/t/46291/uploading-large-games-faq

No one has ever seen a child widget, when created via "add child" to another parent widget (with the palette structure border > scroll box > vertical box, child is added to vertical box) have the text in the child appeared "greyed out" like this?

Any theories?

[scenic fox]

why is my AI appearing dark in my lighting

anyone?

im using static lights

[lucid grove]

Show us

[tame bane]

Hey guys!
Don't know if this is a very basic question, but is it possible to animate cascade particle events?
I have a demo scene that only needs to play once and I'm trying to create some timing between different particle systems firing.
So far the only thing I have found is in the spawn - burst setting but I cant seem to delay it more than 1x the lift time and for some events I'd like some more control.

Is there a way to achieve this?

[scenic fox]

@lucid grove

please help

my ai just goes dark in this area

the lights are static

i still don;t know what's causing this

[lucid grove]

So he aint dark in other places?

but in this specific one

[scenic fox]

yes

just this one

it might be other locations to but i haven't checked

im so confused on why he just goes dark

[lucid grove]

The basic advices just in case:

1. Rebuild Lights
2. Check if there is nothing that blocks light (some hidden collisions or objects maybe?)

Btw restarting editor is also a thing

Sometimes lights have this issues fixed when editor restarted

Is all of these didnt helped

[scenic fox]

i rebuilt the lighting

and it didn't work

[lucid grove]

Place some light source on your character

[scenic fox]

i also did close the engine and reopen it

[lucid grove]

And check if it becomes also black on this area

[scenic fox]

why is it going black tho

i did make the light stationary later and that some how lit up the player

[lucid grove]

Could be: PostProcess trigger, reflection sphere bug, light source problem, some BP issues

Lots of stuff

[scenic fox]

btw i have a lightmass

[lucid grove]

Start with attaching some light source to your AI character

[scenic fox]

i have a lightmass

i think i need to change a setting perhaps?

[lucid grove]

You might try ofcourse

Im mostly working with dynamic lightning

But blackout character mostly caused by PostProcess or SkyLight

[scenic fox]

hmm

my post process has an exposure set

[lucid grove]

Disable it just for testing purposes

Did you attached light source to character?

[scenic fox]

no i didn't

[lucid grove]

Start from this and see if it gets blacked too

[scenic fox]

ok so he is lit up when i put a light in his character

but idk why he is not lit up when it goes to that area

the only time he lits up with the light i put in the level is when i set the light to be stationary or moveable

[lucid grove]

ok so next one

remove roof and walls from that spot (you can just move them away)

[open wadi]

Anyone know how to convert a datetime variable to a string so I can use print string to view the contents?

Normally variable types that aren't strings, when you drag them to a print string, UE4 detects them and offers up some "convert to string" node, but not with datetime

[scenic fox]

@lucid grove my walls are BSPS

[lucid grove]

it doesnt matter 🙂 just move them away and we will see how that affects particular place

[scenic fox]

alright

[open wadi]

Brandy got blacked

[honest vale]

the lights are static
@scenic fox you'll want to use stationary lights

and bake them

[scenic fox]

hmm

why does it not work with static lights

[honest vale]

because they're 100% static

they don't affect dynamic movable objects at all, except via indirect lighting

[open wadi]

By some act of god, has anyone currently awake ever taken created_at or updated_at responses from a Postgres DB and converted them to a datetime var via the "datetime from string" node?

[scenic fox]

@honest vale I actually put it to stationary and when my character goes in the light he lights up but when he leaves he becomes more dark again. Not pitch black like in the picture but he becomes more dark

[honest vale]

build lighting

if you don't build lighting you don't get any indirect lighting

[scenic fox]

okay

[open wadi]

Hi everyone, I have a question: I have a datetime that is returned from my Postgres DB as UTC (0 UTC offset) as the format: 2020-09-05T04:58:55.970Z. I tried simply using the "As Datetime (UTC)" node and, when I attempt to use the nodes to interpret the result, it returns January 1st every time for the date, meaning it's not interpreting that string correctly.

I thought that format: 2020-09-05T04:58:55.970Z - was a standardized format. Why would Unreal not be able to interpret this?

[spare sun]

@open wadi try using date time from iso string node

[sterile tulip]

Im doing something wrong

But I dont know what

[honest vale]

what's wrong?

[scenic fox]

@honest vale just making sure is this normal, the character kinda goes dark cause of something but idk what it is

is it normal?

[fallen marten]

Just looks like it's walking through shadows

[scenic fox]

yeah why?

[fallen marten]

Why? Lol idk man, play with the lighting and see if it makes a difference

Or maybe the the way the material is reacting

[scenic fox]

my lighting is just a stationary point light

[fallen marten]

Are there reflection captures active?

[scenic fox]

yes

there is 1

but it's not in the hallway im in

[fallen marten]

Add one there and have it fill the hallway - see if it makes any difference. Lighting isn't my speciality so there's only so much I can suggest

[scenic fox]

Wait how do i make it fill the hallway?

[fallen marten]

Add one as a box and then scale it

[scenic fox]

ohh

hold on let me try this

[fallen marten]

It should help in some capacity with making the point lights rays less defined if that makes sense

If that doesn't help much, maybe increase the attenuation radius of the lights (I think that's the right one from memory?)

Seperate note - can someone point me in the right direction setting up a material to be able to use the DON mesh effects ? A sample project that uses the plugin (that I can open things up and see how to set it up) would be awesome

[autumn grail]

I have a problem with my niagara emitter , LocalSpace make disappear the emitter

anyone?

[scenic fox]

@fallen marten did i fix it?

?

[fallen marten]

It's hard to tell. Question is, do YOU think it's better? It looks like there's a pretty hard shadow right at the end but I think it's cos the lights are so dim and have a small radius

[scenic fox]

i mean at the beginning it was fine right?

[fallen marten]

I'm looking at it on a phone screen while I'm making dinner so 🤷‍♂️ Dude at the beginning I couldn't even see the character

Just watched again, I'm assuming when it disappears, it walking back toward the other end of the hall. I do think that reflection capture smoothed out the lighting a bit tho which is good

[scenic fox]

So when he starts walking in the hallway is it good?

is it fixed?

[fallen marten]

I guess so... Honestly I was just guessing as to what it was you thought was wrong

[plush yew]

Hello guys I did this with the outline but there is little bug, when I start the game the object is with enalbled coutline, I want to enable collusion when I hover the mouse over the mesh

[fallen marten]

So no one can help me out the don mesh stuff?

[plush yew]

this is the video

I did this code:

can someone help me?

[fallen marten]

https://docs.unrealengine.com/en-US/BlueprintAPI/Game/Player/GetHitResultUnderCursorforObject-/index.html

[tepid veldt]

@plush yew probably you toggle the outline, but you need to set the outline to be disabled by default and only be enabled when you hover your mouse over it

[plush yew]

okay

have you got idea how I can do it? @tepid veldt

[fallen marten]

The hit result, drag off the actor and set collision

[tepid veldt]

Show me the outline graph, @plush yew

[plush yew]

okay

[tepid veldt]

Ok so what you need to do is on BeginPlay you set a boolean. Default value is false.

Remove your Scalar connections to the cursor events.

Then between your On Begin Mouse Over and Set Scalar (...) set the boolean to true.

Then OnEndCursor you set the value of the boolean to false.

Then event tick a branch with the boolean as condition. Drag off the true pin to set your Scalar param of what needs to happen when you hover over the object, and the other way around.

I gtg now but I can make the blueprints for you later today, if you're unable to figure it out

[plush yew]

okay

will try to do it now and send picture here

ops

I sent you the wrong code of the wrong actor

it is for here

Hello, I'm trying to make some AI that will stay on a line and just go straight on the line. I dont want the AI to move off the line. As I'm making a tower defence template for uni and have five lanes, like in 'Plants vs Zombies', at the moment I have two target points, one for spawning and then the other for where the AI will go, but sometimes the AI move off center. So how would I make the ai stay in a straight line?

For now i can save simple variables but it doesn't really help with animation state (for example if enemy half-way attacked me) or some delays that gets ignored by load.

The cheapest way i found is doesn't allow save game while in combat

[covert hedge]

which is what a lot of AAA games do anyway

They block that when player in combat, but rest of the "world" around keep working fine.

this is what the gradients are supposed to do
where there's more blue the wind should move it more
where it's dark it should do it less
blue is supposed to make the entire tree sway
green moves branches
and then red is supposed to move individual twigs
but only the blue one works

[abstract plank]

@lucid grove its not that hard of a trick, no different than any other boolean

Set booleans for if something is able to be saved, when something happens that you would not want it to save during for a specific thing, like attack animation, set it to false during that for that object, then return it to true afterwards. Then make your save program check if something can be saved before it saves it, if not just don't save that thing and continue to the next

You can even separate player objects individually, for example allow the players location to be saved but disable animation state

[tepid veldt]

@plush yew nice :)

[lucid grove]

I have encountered two problems with that:

1. At this point i dont know how to get current animation time. Like when i want to load game and play this animation i want to play it from exact same moment.

2. The other problem that troubles me - AI BB seems like continue playing from the place it was before. Its not restarting. And moreover its not continue from place it was before.

For Animation time i can atleast use notify, but have no idea what to do with AI

[abstract plank]

Ai BB will take a bit setup to get into a save ready state, animation time shouldn't be hard though, animations work on key frames, key frames are specific measures of time, when an animation plays its got a duration length, you can get and set that duration length, so storing that duration length as a save variable isn't hard, just make sure it loads after your character fully loads

For ai you'll need to create a function that runs right after your load function that systematically recreates the conditions that created your bt state. So you can get the current state of any bt simply by checking the active state of all the conditions it's under and checking the current active task it has, that info can tell you exactly what bt node the ai was on, then after everything that needs saved gets saved, you load the ai in, initialize it, keep the game state paused, and feed all the data back to the ai in order so that it's bt navigates to the same node. Then allow gameplay to resume

At least, that's how I'd handle it

This can all be going on during a load screen to, so the player doesn't see what's going on

[lucid grove]

Aha, so i had to get rid of all my "Delay" nodes

At least from most of them

And use timer's instead

[abstract plank]

Yea you will want to disable them at least temporarily when you do that, or you'll be getting crazy long load times

[shut glen]

i am making a 4 players game

but i cant use a controller

it does not work #

[abstract plank]

Hmm, I don't have any experience with networking stuff 😅

Sorry

[shut glen]

its local

it does not use network

[abstract plank]

I would think as long as the controls mapping and everything are set properly, that it should be handled mostly automatically on the instanced players as part of the player character

[shut glen]

Its just that only one player receives input

[abstract plank]

You need to instance them then

They need to run on their individual instances based on spawn order, then match the characters to their associated controller

[lucid grove]

Yea you will want to disable them at least temporarily when you do that, or you'll be getting crazy long load times
@abstract plank Ok, for example i recreate conditions from start. But can i Restart AI BB with some command?

[abstract plank]

Abort

[lucid grove]

Like there is Wait 4s selector that had to be ended to move to the next section

[shut glen]

https://blueprintue.com/blueprint/3-rjz-v1/

this it

the code that spawns the players

[abstract plank]

You can forcefully abort and reset the behavior tree

I assume you mean behavior tree when you say bb, bb or blackboard is mostly just a bunch of variables @lucid grove

[shut glen]

me?

[abstract plank]

No, Jake, sorry

I'm not at my computer right now, so I can't open that blueprint

@lucid grove you might need to use cpp to do it, there's a function I think it's called StopTree() but I might be wrong

And just make sure you have all the necessary flow control in place

[lucid grove]

Got it! Now its not that big scary wolf i was thinking about.

Thank you

@potent prism hard to tell without more info. You can try changing D3D11Commands.cpp. RHISetScissorRect(true, MinX, MinY, MaxX, MaxY) change true to false. Or remove If-else if (bEnable)
{
ScissorRect.left = MinX;
ScissorRect.top = MinY;
ScissorRect.right = MaxX;
ScissorRect.bottom = MaxY;
}
else
{
ScissorRect.left = (LONG) Viewport.TopLeftX;
ScissorRect.top = (LONG) Viewport.TopLeftY;
ScissorRect.right = (LONG) Viewport.TopLeftX + (LONG) Viewport.Width;
ScissorRect.bottom = (LONG) Viewport.TopLeftY + (LONG) Viewport.Height;
}

and just leave ScissorRect.left = (LONG) Viewport.TopLeftX;
ScissorRect.top = (LONG) Viewport.TopLeftY;
ScissorRect.right = (LONG) Viewport.TopLeftX + (LONG) Viewport.Width;
ScissorRect.bottom = (LONG) Viewport.TopLeftY + (LONG) Viewport.Height; instead

atleast you wont get Ensure condition failed 🙂

probably wont fix anything tho

you just need to change your build target to linux

if it wont let you do it you might need to compile unreal from source on linux

[grim ore]

for a dedicated server yes, they need source

https://docs.unrealengine.com/en-US/Gameplay/Networking/HowTo/DedicatedServers/index.html the dedicated server docs should apply

[dawn gull]

Is there a way to get full lighting everywhere, without making the character/object look all weird?

[wide cloak]

Hi everyone my navmesh has created barriers between level objects but the barrier is huge. Does anyone know how to shrink this?

[dawn gull]

Maybe check the properties of the NavMesh?

[wide cloak]

Maybe check the properties of the NavMesh?
@dawn gull Which properties would affect size because I see a ton?

[dawn gull]

Just look at the names

[wide cloak]

Ok thanks I'll take a look

[abstract plank]

That barrier between your objects is based on the boundaries of your trees

Basically, the nav mesh checked that location, returned that it had an obstacle there, determined that obstacle was to steep to move up, and didn't generate navigation data on it

So unless you want your npcs and stuff running up the trees, it's probably fine, there's pathing between them they can follow to not walk into the tree and get stuck on its collision body @wide cloak

@abstract plank Awesome, thanks for explaining. I'm still new to NavMesh. I've noticed that the bounds affect me as well. Is this because of the navmesh or the collider on the tree?

[abstract plank]

I would put down a character model for reference, if 2 trees are close enough together that no nav mesh generates between them, can your character even fit between them? If not, call it good because if your character can't fit between them but you change settings and generate nav mesh between them, then you'll have the character trying to walk between them when it can't, and it will get stuck

The nav mesh doesn't affect player, that's the collider on the tree

@abstract plank Ok thanks, I guessed as much., since I used the foliage tool to paint on the trees, is there a way to decrease the size of the colliders or do I just make an object blueprint and put a custom collider on the tree?

[abstract plank]

When you set up the foliage tool, you had to choose a mesh to use for the tree to paint them in using the foliage tool, find that mesh and there's probably something in that you can adjust

In the screenshot you sent I can even see the edge of a collision sphere around your tree

[hearty dagger]

Anyone know why my project is running at 60 frames per minute. A few hours ago everything was working completely fine.

[grim ore]

have you restarted it?

[abstract plank]

With that limited amount of information, I dont think anybody could troubleshoot the issue in any reasonable amount of time

But I would say the age old, tried and true method of, restart it, would be where I would start too. Maybe even restart your entire computer

[median hound]

anyone do destructable meshes?

[lucid grove]

Have anyone experienced that problem? When im loading game for some reason on BT cooldown timer instead of 0.1s becomes 60 seconds!

Thats UE4 basic "Cooldown" decorator, i didnt touch it or change it in any ways possible.
its even showing that cooldown will stop in X seconds which is random from 15 to 60

[robust acorn]

is there a way to open an auto saved file
I fucked up some shit and would like to get back to a few days ago

[grim ore]

auto saves are basically copies of the existing assets, so you would copy the one from the auto save folder. delete the one you dont want anymore, and rename the autosave to the correct name

[robust acorn]

this is the only thing in the autosaves folder

[grim ore]

and in the game folder?

[grim ore]

yep.... so you need to find your save you want

if you mean you want to go back a bunch of files, you might not be able to. You should be using source control for that

[robust acorn]

source control like?

[grim ore]

source control. Perforce, git, svn,cvs.

its too late for that at this point

[robust acorn]

oh there are only 3 or less save files in each folder

only changed since a day ago and thats when I made that mistake so im going to rewatch the lecture I watched and redo it

[sleek karma]

hello i have a question, how can i change the length of a slider in ue4?

when i try to change the scale it just gets stretched i can not change the slider length when its in a box for example a horizontal box

[robust acorn]

It is fixed by the way for if you wanted to know I was debugging some and found out why the ai wasnt roaming

[grim ore]

@sleek karma can you show the screenshot of the issue?

[sleek karma]

@grim ore

there is now way to change the size

[grim ore]

parents control children in UMG

[sleek karma]

yes

[grim ore]

so you need to adjust your parent, there is no fixed size unless you wrap it with a size box

[sleek karma]

wait please

like that?

[grim ore]

if you do that you can now set an override for the height and width

but its not going to get any larger than the parent allows it so keep that in mind

[grim beacon]

Tomatoes?

[sleek karma]

so i cant change it

only if i do it in the canvas

[grim ore]

your slider is in a horizontal box, what is the horizontal box in? what is the horizontal box set to for sizing

[grim beacon]

Not sure but maybe a scale box would do the job?

[sleek karma]

no i tried already

[grim ore]

isnt your horizontal box in a canvas panel?

[sleek karma]

it is

[grim ore]

so size the horizontal box to the size you want all of the contents including the slider

[sleek karma]

nothing changes

[grim ore]

the horizontal box just lays out the contents to the max its allowed, the contents inside you set to fill evenly or unevenly

what are the settings for the right side options menu

[grim ore]

nope

your in the completely wrong section

you should not really mess with those

the top of the details panel when you have a widget selected are the settings relevant to the parent

[sleek karma]

that one?

[grim ore]

yep

thats where you adjust the size of the item, or scaling or fill, depending on the parent. in this case you can set a fixed size since the parent is a canvas panel

it seems like you are trying to do something like this?

[stark cipher]

At this obj. why is it like this?

[mental apex]

does anyone know any good animating fps hand tutorials?I cant seem to do the run animations

[stark cipher]

And when I place it on the level,its invisible. Can somebody help me please?

[grim ore]

use print screen, we cant see anything

[grim ore]

is this supposed to be something?

press the F key to focus on the object

[stark cipher]

Yeah,an object exported from Blender

Now I can see it,but on the level its invisible

[grim ore]

well if you hit F and then can see it, I have a feeling its super small

it could also be a bad material, or bad UV's. we cant see what this looks like

put it in the level and hit F to focus when its in the level

[stark cipher]

Its very far from where i put it down

[grim ore]

you might have the pivot point in the wrong spot in blender

if you are using blender the 0,0,0 point in the world is the pivot point for the item when you export it so make sure you move your item to the world origin (0,0,0) in blender

[stark cipher]

K,i'll check that out. Thanks.

[limber mesa]

can anyone help me out, i have a sphere that overlaps an enemy which happens, i made it so that if it overlaps an enemy within that class it checks to see if its that particular enemy, but the false gets executed,any suggestions?

[covert hedge]

so a lot of random stuff that if find weird in your blueprint

what's the matter exactly, you want to detect a collision with a particular actor right?

@limber mesa

[limber mesa]

yes within that class

[hearty walrus]

is there a way to make more fine-tuneable settings?

hello all , should I install UE4 on SSD or HDD

or UE4 can be on HDD and projects on SSD ?

what's the best practice

[worn peak]

should I create the materials on external programs or import just the mesh and create the materials inside unreal ?

[covert hedge]

you should find a lot of plugins to import materials from external programs, but the choice is yours

[worthy fox]

How can I make my AI's play turn in place animations? To get the speed the AI is moving at I get the Vector Length of the Velocity.. that's all I know for now. But how do I know when he is rotating?

[worn peak]

@covert hedge do u know if theres a plugin for blender~unreal

I tried to export some glow materials but didnt work pretty well

the nodes are differents so it came to mind that maybe its better to work with materials only inside unreal

[covert hedge]

you might end up just extract every texture you used to create material and recreate in UE4 then..

i had no trouble creating somes with textures from substance painter

[plush yew]

Hey I got a question hopefully someone can help

I made this bush, but the lighting makes it look bad..

does anyone know whats up?

[worn peak]

@covert hedge so I learned materials on blender for almost nothing pepesad

@plush yew maybe I do, I guess the lightning its making it look bad

jk, have no ideia

[covert hedge]

nah i mean materials are probably the same in blender

[plush yew]

its roughly the same in blender yes

you call the same shit like specular and roughness etc

[worn peak]

nop its not

[covert hedge]

with the channels albedo etc, UV map, roughness etc etc

[worn peak]

some inputs are the sames

others not

like emissive ie

[covert hedge]

there are probably couples of guide around to "translate" the non-corresponding nodes

[worn peak]

it seems quixel works better for materials when comes to unreal than blender

guess I'll learn quixel and uses blender for modelling only

[covert hedge]

i have yet to test their mixer or whatever they call it

but the default materials you can import from bridge are cool

and free

[worn peak]

no, the quixel

oh

yes

its called mixer actlly

quixel its the company

or whatever

[covert hedge]

if only i had a sharpen creativity all those free assets and i do nothing

quixel bridge is their asset downloader

mixer is to mix textures i think

[worn peak]

put digimon and pokemon together

call it dikemon

and get millionare

[covert hedge]

[worn peak]

pogimon maybe

no

dikemon its better

how do u got those twitch emots

dont keep them to yourself

how would I make a flower sway in the wind like you can do with simplegrasswind?

should I not model the stem?

I want the whole flower to sway. stem head and leaves

Does that make sense?

[spare sun]

simplegrasswind makes the whole thing sway no?

[plush yew]

just the texture, not the actual model

[spare sun]

you wanna make the texture sway?

[plush yew]

like what if you have a rose, it has a stem, the rose, and maybe like 2 leafs right?

but its not on a plane

[spare sun]

simplegrasswind works on meshes just fine

not only planes

[plush yew]

eh it doesnt really work that well it gets disconnected lol

[spare sun]

well yea you'll have to tweak the parameters. simplegrasswind isn't anything bound to physics, it's simply visually displacing the vertices

[plush yew]

ah yeah one parameters was off

it works now

didnt know it worked with models thats cool

thanks 😄

[fresh iron]

hi! somebody know for why my shadows are too dark?

[abstract plank]

How dark should it be? Is the texture itself dark or is it only dark when put in? Have you set your exposure settings? What's your lighting settings? Need a bit more information to answer that than just a picture please

[cerulean lotus]

theres a very strange hole appearing in one of my models, but only this version? and im not entirely sure why?

ive got an almost identical version of this model where the issue isnt appearing

in blender itself, the model doesnt appear to have any issues

@abstract plank i think the ambient oclussion its too high, but in my ppv the ao its to low, i need the lees dark , how i can make it? increased the sky light?

[abstract plank]

Do you have a exposure volume placed on the map?

If so, you can go into its details, go to the exposure tab in its settings, and change the minimum and maximum both to "1"

If you don't have one placed you can place it and do that.

If you have already done that and it's still dark you can play with your scene lighting, check all the values to make sure they're right, and even change exposure level although I'd recommend keeping it at 1 and finding out why it's dark at 1 it should be plenty bright enough

I won't be much help past that but maybe someone in #graphics can help you further

Or #level-design

[hot canopy]

@fresh iron Two questions: is the material in your foliage set to two sided foliage? Do you have a skylight?

@cerulean lotus Almost certain your normal is inverted in that single face.

[cerulean lotus]

thank you! i thought i had already tried recalculating the normal, but i guess not. thanks for the help!

it works fine now

[gentle trout]

how can i hide the camera?

[next badger]

@gentle trout in editor?

[gentle trout]

yy

im new and i want to hide this camera

[next badger]

select it an hit H

[gentle trout]

i did it but if i do that the caracter hide together

[kind dew]

also the camera will dissapear when you hit play

but select in and in the details panel uncheck Visible

[next badger]

there is not Visibility setting for camera components

[gentle trout]

oh ok

[next badger]

you can replace camera to some empty mesh

[median hound]

y wont it come after me

[plush yew]

anyone know some good lighting guides??

Are there any animations out there on the marketplace or anything of one character carrying another character over his shoulder?

[next badger]

@plush yew yes

[plush yew]

thanks! thats a lot of material omg haha

does that include shaders? or is that totally different?

[next badger]

@plush yew iirc just the lighting and color grading (LUT tables, exposure etc)

[plush yew]

ah so no postprocessing then?

[next badger]

LUT and exposure is PP

[plush yew]

hahah okay 😄

[narrow mauve]

What in the bleep do I send here as the object? parent class is wheeled vehicle

[open wadi]

Question: I have a dynamic amount of data ("posts") returned from my API, and for each post, I have an "individual post" widget - I have a for each loop and loop through my array of posts, create individual posts widgets for each, and insert them via "add child" into the Scroll Box > Vertical Box in my parent "All Posts" widget.

The issue is, despite cycling through the results in order, the "individual post" widgets are appearing in my Vertical Box in random order, likely due to Unreal simply inserting each of them once they get done being generated.

What is the best approach to ensure my posts appear in the correct order (the order in which they are in the array) in my Scroll Box > Vertical Box?

I suppose, I need a way to divide my Vertical Box into numbered segments, and ensure when I "add child" it goes into the proper slot - keeping in mind that I have a varying number of "posts" at any given time, and the posts themselves can vary in size.

Is this even possible?

[next badger]

@narrow mauve well, you send there an object reference you going to cast to this class

[restive zinc]

I have a question for anybody working on a third person shooter i have a aim offset all set and ready to go and all the code is set also Now how do i make the player look at where the camera is or rotate towards it anybody get what I'm saying do i use "Use Controller Yaw" or what???

or look where the gun is pointing

@plush yew have you tried restarting your pc

[celest vapor]

is it possible to attach a component to a socket only inheriting the location and rotation but not scale?

[restive zinc]

huh

you have a backup

if not

start all over

no

using UE Version 4.25.4

what happened that made your project crash before

no backup

[limber mesa]

Anyone have any ideas on what they would use if they wanted a magic ability to damage an enemy, besides use a collision sphere or box?

Same methods as any weapon, it being magic ability doesn't matter too much, you just need a damage method and function

[neat current]

I've a question.
I'm creating my first scene in Unreal. Added a 2K texture in the scene and Unreal gave me the "Texture streaming pool over 20.43mb budget" warning. My streaming pool size is 1000.
So, I opened up an Archviz sample project. It has 2K textures as well and it's streaming pool size is 1000 too but I don't see the same warning in the scene.

So why I get this warning in my project, but other project is all good?

[abstract plank]

You can even just have it be a hit scan if you wanted

(Check targets location, check that they would take damage from the source given a set of parameters, then just subtract the damage amount from their health value)

[open wadi]

Is it possible to add items to a List View at a specific index?

@open wadi

[median hound]

anyone know how to fix when i put my ai on nav mesh bounds it greens out everything except where the ai is

[arctic horizon]

make sure physics components (mesh, collision boxes, etc) on your actor don't have "can ever affect navigation" checked

otherwise they're blocking the navmesh

actually, that might be a setting on the actor itself as well

[median hound]

alright ima check it out

[open wadi]

@abstract plank I found that guide already, perhaps I missed something, let me re-read it.

Ok so out of the gate: Note!:If a widget is generated for one instance more than once, the engine will crash. So any instance should only be in the listview once.

So in my case, I'm building something akin to a simplistic FB wall.

So I have an "all posts" widget, and an "individual post" widget. I pull all my posts from my API, I load them into a local array, then I loop through them and with each one, generate an "individual post" widget, then add it as a child to a vertical box within my "all posts" widget.

[abstract plank]

Oof

[open wadi]

The issue I'm having is they are appearing in random order, as the "create widget" function is async, so they're appearing in random order within the Vertical Box.

Otherwise it works fine.

So I need to be able to have them appear in the proper order.

Also, if one were to say be, deleted by an admin, and that information broadcasted to my UE4 clients via WebSockets, I need to be able to reference that "individual post" and delete it

So for example, when I first pull and create all the individual post widgets, I simply need to be able to say "Ok this is individual post 2, put it at index 2 (or 1 if starting at 0) within my All Posts" widget.

[abstract plank]

Getting a bit outside my experience

[open wadi]

Ok.

Well disregard then, I appreciate the help just the same.

The root of the issue is simply this: I just have a dynamic list of widgets that can vary in both physical size and number of entries, and I need to be able to "add child" them to a parent widget at a specific index.

That's the TL;DR

[abstract plank]

You can't set them in the array then pull then in order?

[open wadi]

I mean

[abstract plank]

I'm confused why its randomizing

[open wadi]

Like I was saying, "create widget" is async, so they're getting created at varying times by split seconds based on the amount of data involved.

Or if, for example, the individual post widget has to pull the "profile image" for the user from the web instead of the local cache

So they're ending up in the parent widget not in order.

And also, I need to be able to reference them individually anyway.

So I can delete one if needed.

[abstract plank]

Set a wait or delay on one then, would that not fix it?

[open wadi]

Will that help with being able to later reference them individually? I suppose so if I wrote a "get all widgets" node.

Or used, rather, I could go find the individual widget somehow within the list, if I needed to delete one later.

Or add a comment to one.

[abstract plank]

Should be able too

[open wadi]

Hmm

[abstract plank]

I can't see why not, but I've never tried

[open wadi]

I mean I suppose I could fake it, but some of the images are a bit large, so there could be quite the delay, and there can eventually be many posts.

I'd rather just have what should be insanely basic functionality to have a grid of some kind and be able to insert things at specific positions, or in order, like an array.

Instead of forcing users to sit there for extended periods.

But if that's all that's available.

We do what we must.

[abstract plank]

My extent of that system is a basic global chat

[open wadi]

Right.

Or imagine a high score table that is dynamically updating.

[abstract plank]

I hate the UI myself but I'm stuck in it.

i'm looking for a tutorial that will help me create an extensive landscape, no sculpting, because i want miles and miles and to use the 'levels' system, anyone know a good tutorial?

[nova spruce]

https://www.youtube.com/watch?v=gMKjIZMPJ0Q&list=WL&index=32

this is the original @radiant fable

https://www.youtube.com/watch?v=PDlGKZ1c3Zc&list=WL&index=34 and then they updated it

[dense gate]

The lad said no sculpting, keep in mind

[nova spruce]

no sculpting landscape? like importing heightmaps or just flat ground?>

[dense gate]

I think the objective is to find a sort of procedural generator for a landscape

[nova spruce]

oh, like generating from a random seed?

[dense gate]

I guess

[nova spruce]

seems like skipping a step before learning about sculpting

[dense gate]

Because miles and miles of landscape done by hand will be pain

[nova spruce]

broadstrokes I suppose, I could see that being annoying

miles and miles of any landscape would be impressive

especially for someone just beginning to learn about the tool

[dense gate]

I think what the lad needs is a procedural mesh generator but that'll still be a pain to do

[nova spruce]

probably should learn how to do it by hand to start, at least once.

then work his way up to procedural generation
