Hi, i actually have an animation blueprint that make my player walking/jumping, but on overlap the thirdpersoncharacter has a play animation block. After animation ends it still remains in last animation frame position and don't follow animation blueprint anymore? How to make the third person character follow animation blueprint again ?

Thank you.

[plush yew]

haya folks quick question if someone please has some time! Ive exported a skeleton mesh from the engine and imported into maya however when I try to import it back a error pops up saying it has duplicate bone names

does anyone know how to fix something like this?

[rough knoll]

issue still persists, i can't paint foliage anywhere except on static meshes.

i have these ticked so this isn't a problem

unticking static mesh doesn't let me paint foliage anywhere

[sterile tulip]

maybe there is some collision around the house preventing foliage

[rough knoll]

i deleted the house and it still didnt work :/

[sterile tulip]

I dont know then

If you havent sculpted much you can recreate landscape

[rough knoll]

not really an option for me

i have a whole mountain

[sterile tulip]

try on landscape mode>manage>resize/change component size>apply

[vestal pond]

would it be better to code or use blueprints? I am also currently using unity and wondering if I should switch

[lean gazelle]

i prefer code personally

up to u

[sterile tulip]

If you can code you can code but nowadays you dont need code anymore to create games

You can do anyting with blueprints

[dawn walrus]

Well, uh. Hello everyone! It's nice to meet you! I'm... Brand new to Unreal Engine. And I'll probably mess this up a lot. But. Hey. That's half the fun of it, right?

[plush yew]

you can ask for help at anytime everyone is very nice here.

[sterile tulip]

Welcome!

[timid frost]

Hey I am new in game developing need help unreal engine 4

[dawn walrus]

Thank you! I was hoping to try to get some practice in with simpler projects at first, and then try my hand at a bit of a more complex thing. Y'know. Just to get the hang of this. I've never done coding for an AI or the likes, so that's the newest thing to me.

[sterile tulip]

Im also new, just started a couple weeks ago so you wont really get help from me but here are some people who know some things

[timid frost]

Can u please tell me how to make stuff fall automatically when your character reaches that point trying to make horror game

[sterile tulip]

I think you need to activate physics in overlap with a collision box

[plush yew]

@dawn walrus well, there are tutorials everywhere! along the way you will get super familiar with the layout of ue4 and learn a bunch in code or blueprints whatever fits you.

[sterile tulip]

You go to your things which will fall and add a collision box or box, then press + on overlap to make overlap node

[timid frost]

Thanks

So which book or articales should I need to read to become good game developer

[sterile tulip]

I recommend to watch a few series on YT how they make a complete game so you get some understanding of nodes

[timid frost]

I am new just started three days ago

[dawn walrus]

Oooh! There's whole things like that? My usual way of learning is to take what they do and work alongside them, taking what they give me to see what I can do with it.

[sacred scaffold]

Hello everyone! I'm trying to spawn my ThirdPersonCharacter into a level but I can't see it's model. I set up the PlayerCpntroller with the proper inputs. When I spawn in the map I am able to move but not see the model properly. Any help would be greatly appreciated. 🙂 DM me please.

[plush yew]

well i think first things first you should learn blueprints instead of code it might be easier for you when just starting but also get use to the layout and where some things are then go from there just mess around with it really

[sterile tulip]

Once you learn how nodes work you can create your own nodes

[lucid grove]

heya, that damn CapsuleComponent killing me.

when activate physics its deattach from mesh

[plush yew]

Can I change StaticMeshes pivot point in runtime?

[lucid grove]

when i try to attach it again - its behave weird: mesh is on top of capsule

[dense gate]

Is the capsule component your root component?

[sterile tulip]

Are all Megascans textures available in free epic marketplace or only a small part?

[dense gate]

I think all are free

When looking up "megascans" on the marketplace and setting a filter of 1 EUR min, I get 0 results

[sterile tulip]

Nice

I will try them out

damn man

12 gb for a texture pack

With assets this big no wonder games reach 100gb

[rancid lynx]

whats the advantage of using event dispatchers? ive watched a few videos and i dont understand so well

what can they do, that others cant, or better?

[autumn elbow]

@rancid lynx Dispathers can send 1 signal to multiple receivers. All others are 1 signal to 1 receiver.

[rancid lynx]

thanks!

they still reauire preganted actor references i guess right?

[autumn elbow]

You can get Inferfaces to do the same, but you'd have to use loops or inheritance.

Yes, all of them need a reference

[rancid lynx]

i like interfaces ok ty

[plush yew]

go to 4.17

Question - When viewing the "Lightmap Density", selecting an object makes it appears pink, you longer can view the density based off the Red,green, blue scale. How can you make the selected object remain red, green, or blue?

[tired lynx]

could somebody tell me why, when doing a render pass, my world normal render pass starts off like this for the first couple of frames (which is what i want)

but then turns into this a frame later:

[dense gate]

The first 2 frames look like they're normals

[tired lynx]

yes

i am doing a world normal pass

the first two frames is the result i want/would expect

the rest isn't

[open wadi]

Question: I have two custom BP structures: Module and Video. The "Module" struct consists of a map to the "Video" struct - the "Video" struct simply has 6 strings.

I then declared a GI variable, "ProgramModules", which consists of this Module struct. I need to be able to perform two searches - One to search the "Module" key part of the map to find which module I'm looking for, and then to search the "videos" of that module once found.

In this example, I've broken out "Program Modules" into the individual struct keys: "Start Here" and "Module 1"

[dense gate]

Aight, realized I misread, sounds like a bug

[open wadi]

I don't know that I should be breaking out the struct, perhaps it should stay concatinated.

How would one simply search the keys of a struct to find a match? Should it be a "for each with break" loop or is there something more efficient?

[dense gate]

You can somewhat safely do a foreach search

You just need to search for Names

Avoid string compare like the plague

[open wadi]

Right, foreeach just seems to be an inefficient way to code this, but if that's the only option.

[sage coral]

This will prob sound silly and simple but how would/should I go about making a melee system like your typical block, dodge light attack heavy attack and combos? been looking for weeks about how I should go about doing this but iv gotten to the point where I need to ask lol

[open wadi]

MidnightProdigy: I'm quite sure there are many guides on YouTube, that's an incredibly complex topic, building something out like that from start to finish.

@dense gate Normally, when searching a map for example, Unreal provides the "find" node.

Are we saying foreach with break is the most logical course of action, or might there be another more efficient node?

[sage coral]

Been looking at the guides its just hard picking which one is the right one as well as if its been optimisted for the new engine I was seeing alot of the tutorials were years old Im not sure if UE changed anything in thouse times if that makes sense?

[dense gate]

Find does the same thing as for-each-break, just in a single node

[open wadi]

Well yes, but what you're asking is far too complex, things change from version to version but you're going to have to put in the work, no one in this channel is going to build out an entire melee system for you.

[sage coral]

thats not what Im asking I dont want anyone to do my work for me

[open wadi]

@dense gate Really... So find is literally a fore each break node.

Well that's news.

[dense gate]

Names speed that up a ton tho

[open wadi]

In that case, might as well write it manually!

[dense gate]

They are case insensitive

[open wadi]

Thank you much, very helpful.

[sage coral]

I was asking in a professinal stance where whould be a good part to start insted of searching on the internet hopeing to figure it out

[dense gate]

Start from designing it

How do you want to block, attack, etc

[open wadi]

MidnightProdigy: In your case, the professional stance is to search on the internet and figure it out, yes.

[dense gate]

Then think how these interact between each other

[open wadi]

I recommend Udemy or Pluralsight for initial guides.

Otherwise, simple YouTube searches. Find something as close as you can to what you're trying to do and go from there.

[dense gate]

Example of a for-each

Though not in a struct array

[open wadi]

And FWIW, I found Pluralsight far superior to Udemy in terms of instructor quality, FWIW.

Back when I was in that stage.

[sage coral]

Iv jumped from Unity to Ue4 back and forth sorry if I got confused a little 🙂 thank you for the suggestions tho ill defo look into them

[open wadi]

Udemy literally hires teachers that sound like they're passing out and leave dozens and dozens of mistakes in their training and simply go back over the videos with text overlays saying "Oopsie so this is wrong here it's actually this"

[dense gate]

Also, when you exec a return node in a function, it breaks the rest of it, like they'd do in programming languages

[open wadi]

Instead of updating the content.

@dense gate Reviewing screenshot, thank you.

[dense gate]

Should be the same thing with you, except the input will be your array of structs and out comes whatever you need from it

It'll end up wider 100%

[open wadi]

Well mehteh this is the complexity of it: For example, here is my struct:

My struct is a map to a struct.

[sage coral]

So say I have 2 players ones ranged and ones melee would it be easier to fully make both ranged and melee on one character and to make a child of the parent as your ai follower or to fully make both characters combat system sepratly?

[open wadi]

Both custom.

I'm not sure if that matters.

So the keys are "Start Here" and "Module 1", and each of those has some 6 string keys (that come from the other custom struct): Title, URL, so forth.

[sage coral]

ranged player can never pick up and or use melee weapons and vise versa

[open wadi]

So when I branched it to a Foreach break, it converted to an array.

Should this search operate as expected?

Step one is "searching the keys", which in this context is "Start Here" and "Module 1" as seen in the previous screenshot.

[dense gate]

@sage coral I personally have a "unit" class that basically every single pawn inherits from, then to each of them I can attach different properties, abilities, items, status effects, etc

[open wadi]

So I want to see if String A matches either "Start Here" or "Module 1"

[dense gate]

Depends on how you wanna go for it

Ah, search through struct

Well that's gonna be a daft bastard

[sage coral]

@dense gate Oh great Idea I didnt even think about that I can even use that as a base to make each different eneamy type wether they use ranged, melee or both

[dense gate]

Yep

[sage coral]

TY 😄

[dense gate]

And off you go

Good luck

@open wadi that isn't gonna do much tbh

[open wadi]

What do you mean?

[dense gate]

I'm still confused what you're trying to search through

[open wadi]

I'm trying to search the keys.

There's my Module struct.

[dense gate]

Break Program Modules, then search through the outputs

[open wadi]

It has two keys: "Start Here" and "Module 1"

Ok, I had it broken out before, once it's broken what node do I use to search the outputs?

[dense gate]

ForEach

They're arrays there right?

[open wadi]

Struct broken out.

These are not arrays, no.

[dense gate]

Huh

[open wadi]

The Module struct is a map to the video struct.

The video struct simply consists of 6 keys.

Which are all strings.

[dense gate]

Hollup

So you have your Program Video struct

Then you have 2 arrays of those in a Module

[open wadi]

Video struct.

Module struct (which is a map to the video struct)

[dense gate]

Modules is a non-array, non-map, non-list variable

[open wadi]

Then I simply declare a variable "ProgramModules", which is a var of this struct type.

[dense gate]

The bottommost selection is the one you need

I think you got confused

[open wadi]

The bottommost selection on which of the two structs?

[dense gate]

I think Modules

Aight, so see here

Things might break

[open wadi]

Are we sure my structs are created incorrectly?

[dense gate]

On the BP where you have Program Modules, click to change that variable type

And select the one that's square-line

As is on the screenshot there

That will create a proper map

You've went on a humongous tangent to create your own map

[radiant jasper]

how would make a number selection in a widget bp. like <1> (press arrows to make number go up/down)

[open wadi]

So basically, what I'm shooting for here is I want a module struct that consists of a series of videos, and each video has multiple properties: title, URL, so forth.

[dense gate]

And this is what it needs to look like

[open wadi]

The way it's designed now, at least from the BP custom structure editor, it appears to be designed correctly: I can declare "Module 1", "Module 2", "Module 3", so forth, and within each Module, I can add multiple videos: "Video 1", "Video 2", "Video 3"

Ok

[dense gate]

Since you're going for a map

Though array in array is iffy

[open wadi]

Oh I see.

I had it set to array.

lol

Thank you.

[dense gate]

I realized you were the lad yesterday that I think I recommended map to

[open wadi]

Apologies, I'm used to simply just writing this shit out in C or node or whatever, where it's just myvar = { "bob" => { "jane", "jimmy", "joe" } };

[dense gate]

It took me a bit of staring

[open wadi]

Yes, thank you, great catch.

[radiant jasper]

does anyone know how to do what i want

[open wadi]

lol

[dense gate]

#umg might have answers

[radiant jasper]

is that a thing in the pallete

[dense gate]

There's a number dial iirc

[radiant jasper]

huh

[dense gate]

Spin box

[radiant jasper]

ok

[dense gate]

In your widget BP you can then add input controls

[radiant jasper]

yeah

[dense gate]

And that should get it done

Just remember to set ranges right

[radiant jasper]

mhm yeah im gonna have it spawn a number of enemies based on the number

[dense gate]

Then spin box should be the thing you need

[radiant jasper]

is there a way to make the arrows bigger

and get rid of decimals

[dense gate]

Check the widget style section

[radiant jasper]

ok

[dense gate]

Set min and max fractional digits to 0

And set the delta to 1

[radiant jasper]

ok and the arrows look like dog shit when i make em bigger lmao

[dense gate]

Yeah, they're a small image

You can make your own in Paint for 2 minutes

[radiant jasper]

how would i even go abt making them buttons

cuz how would it know which one is down and which one is up

[dense gate]

This is getting a bit deep into #umg and it's too late for me

The spin box basically goes up or down depending on how you move your mouse

[radiant jasper]

huh

[dense gate]

Just goof around with it

Try a few things

[radiant jasper]

ohh its a typing thing

ok

[dense gate]

Or drag

It can be both

[radiant jasper]

yeah i see

[brittle adder]

@radiant jasper send me the link to your shapiro game

nice thx

[radiant jasper]

ty

paid $40 for the model of ben shapiro lol

[brittle adder]

😂

[open wadi]

I just paid a couple hundred for a proper backup drive and software for my new development box.

Worth every penny, re "I forgot to save yesterday"

Decided on Acronis True Image 2021

Because I lost 2 hours of work the other day due to being completely ignorant to how Unreal handles redirectors

And just hauling off and renaming / deleting project directories.

[brittle adder]

oof

[open wadi]

Trying to rename my directory structure.

I was comparing Content Browser and the actual Contents directory on disk and saying "Why the hell is this old directory name still present, that needs to go"

Everything exploded.

Never again.

[brittle adder]

😭

[open wadi]

Since Microsoft cannot seem to figure out how to include a backup solution as good as Apple's TimeMachine in their native OS, I bought Acronis.

And one of those 5 TB Western Digital "Black" drives

[brittle adder]

You didn't click to "Fix redirectors blah blah blah"?

[open wadi]

And shit is rolling, hourly incrementials, encrypted backup drive, verification on every backup, etc.

skuba: Hard to fix redirectors when you've hosed the redirectors from the disk.

[brittle adder]

@radiant jasper the hud was kinda weird in my resolution

nice music btw hahahaha

[radiant jasper]

yeah it gets cut off

ima fix it innabit

[open wadi]

I was completely confused as to why files appeared on-disk in the contents directory for the project, yet you would not see them in the content browser - I now know that those old placeholder files that do not appear in content browser are presumably redirectors.

lol @ "gj u won heres a picture of ben shapiro"

[brittle adder]

yep

[radiant jasper]

how would i go abt spawning a number of actors based on an integer

[open wadi]

And I have now learned - "Just don't rename shit. Roll with it, fuck it. Fix it in version 2."

[radiant jasper]

and setting that integer to the value of the spinbox

like in a binding

[open wadi]

You should pay someone to animate ben shapiro dancing, akin to the avatars used in pubg and their little dancing animations

I'd pay for a game to receive that as an award

Ben shapiro breakdancing

[radiant jasper]

lmao

[brittle adder]

or just go to mixamo.com

[radiant jasper]

the ben shapiro file i got doesnt work with mixamo lol

the textures r seperate

and when i upload the folder it just doesnt work

[brittle adder]

upload just the fbx model

[radiant jasper]

the fbx doesnt have textures on it tho

[brittle adder]

you just import the textures to UE

[radiant jasper]

the way i had to do it is get a ue4 project with shapiro in it and transfer it from that to my project cuz the importing wasnt working

[brittle adder]

and create the materials

[open wadi]

It's fun to study the code from those old Sega Super Scalar games from the mid 1980s, back before the transition from sprites to polygons, when those guys were creating 3D environments entirely with algorithmic sprite scaling.

[brittle adder]

embedded textures is not a problem not a barrier to make it work

[radiant jasper]

when i tried manually assigning the texture materials it just wouldnt wanna work

[brittle adder]

you can export the model from UE and then import again

[radiant jasper]

the thing has like 7 million polygons so that might have something to do with it

[brittle adder]

😱

that may be it

[radiant jasper]

so how do i get this value

its a binding for the value in the spinbox but idk how to assign it as a variable

[plush yew]

[radiant jasper]

would i just connect the variable to the return node

and then how would i spawn the actors based on the float

i cant find any tutorial on it

[sterile tulip]

Is there a way to add foliage in meshes?

[open wadi]

So the same issue remains.

This is my custom module struct, which is a map to my custom video struct. My video struct simply contains some ints and strings, such as "Title", "URL", etc.

I declared a variable in my BP function to use the custom module struct, ProgramModules.

I do this so I can replicate the functionality of a JS statement like ProgramModules = { "Module 1" => { "Video 1" => { "Title", "URL" }, { "Video 2" => { "Title, "URL" } } };

That's all well and good, but now I simply need to be able to search the primary keys of ProgramModules. I need to be able to iterate through it and see if a test string matches "Module1", or "Module2", so forth.

The problem is, if I keep the struct together (not split struct pin), the find node appears to take no parameters.

If I split out the struct like this, how would I iterate through all the keys sequentially to see if any of their names match the param without simply creating a branch statement for each one?

Surely there's a way to simply search this ProgramModules variable for primary keys that match a string.

I suppose, the question is: how does one iterate through multiple map variables?

Is that possible?

[radiant jasper]

does anyone know how to get the value from a spinbox?

like get what the player set it at

[open wadi]

So I presume there's just no way to do this.

It looks like BP map support was only added in 4.15 so it's a bit lacking.

That's a shame, in any given standard language it would literally take two seconds to construct such a variable.

myModules = { "Module1" => { "Video1" => { "Name", "URL" }, "Video2" => { "Name, "URL" }, "Module2 " => { "Video1" => { "Name", "URL" }, "Video2" => { "Name", URL} } };

Apparently such variable structure explodes in Blueprint format.

[dawn sentinel]

Heya. What's the unreal documentation like nowadays? I work primarily in unity and was always very disappointed with how lacking Unreal's docos were. If it's still lacking today, is there plans to work on it heavily?

[supple totem]

@open wadi if you wanna do a map in a map you can nest the inner maps in struts

[open wadi]

@plush yewwla I have a map in a map.

@supple totem

The issue we've been discussing in here this afternoon is the fact I cannot simply determine how, in Blueprints, to search the map for a specific key.

Ok, so if you're familiar, let's do this again.

I have two custom structs: Module and Video. The logic is, I have multiple modules, each of which contains multiple videos. Therefore, "Video" is a series of strings for URL, Name, Title, etc. Module is a map of Video. Therefore Module1 => Video1 has the properties URL, Name, Title, etc.

For example, here is my Module struct.

Pretty straightforward. It's literally how you would declare a variable in a language as rudimentary as Javascript as ProgramModules => { "Module1" => { "Video1" => { "URL", "Name", "Title" }, "Video2" => { "URL", "Name", "Title" }, "Module2" => { "Video1" => { "URL", "Name", "Title" }...

In my Blueprint, I simply declare a single variable: ProgramModules, and set the type to my custom Module struct.

That's all well and good, except for the fact that I cannot find any example of how to iterate or search for keys or values within this variable. All the typical Map search operations: Contains, Find, etc, do not seem to work properly. I'm happy to For Each Break over it, but I can't even determine how to, in this case, iterate over the Modules.

So for step one, all I want to do is, within this ProgramModules variable, be able to search the keys for a specific Module.

I've even tried wacky things like converting the struct to a Json object using the SocketIO library, no dice.

Surely there is a way to do this within a Blueprint.

[arctic horizon]

Trying to figure out exactly how you have your structures setup....
Do I have this right? You have ProgramModules which is a map of <something> to Modules. If that's correct, what is your key type (<something>)?

Or is it that you have a map of modules => videos

[open wadi]

It's set up exactly how you see it in the screenshot above.

It should be exactly like this: ProgramModules = { "Module1" => { "Video1" => { "Name", "URL" }, "Video2" => { "Name, "URL" }, "Module2 " => { "Video1" => { "Name", "URL" }, "Video2" => { "Name", URL} } };

There are more properties to the videos than Name and URL, but for simplicities sake, I'm writing it like that here.

Here, let me post even more concise screenshots.

[arctic horizon]

I'm confused because it's not clear what you're trying to access to me.
You have a structure with a field named "Module1" that's a map. Are you trying to access the Module1 field by name? Or are you trying to access an entry in that map?

[open wadi]

Module struct:

Video struct:

The variables in "Module" are maps to "Video"

Then, in my Blueprint, I declare a single variable: ProgramModules, and I set it to my custom Module struct type

In terms of what I"m trying to access, I simply want the ability to, within a BP, search the keys in ProgramModules to see if, for example, a string set to "Module1" matches "Module1", so I can then access "Module1" and get the Videos specified within.

[arctic horizon]

Yeah, so that's not possible. You're setting things up the wrong way to be able to do that easily.

[open wadi]

It would literally take me 5 seconds to write in Ruby, C, Javascript, Pascal, probably BASIC, but in BPs I have to find a mystery node that I cannot determine.

Right, that's what research indicated - Maps themselves weren't even added to BPs until 4.15 and their functionality is still quite basic.

[arctic horizon]

Your "Module" struct stored in ProgramModules is not a map. It's a structure that holds two fields

That's what I'm understanding is your issue

[open wadi]

Right, so you're saying it's impossible to search a struct by field name?

in BPs?

[arctic horizon]

Correct, because that's not what structs are for.

[open wadi]

So what are structs for in this context?

[arctic horizon]

Use one field, a map of string (or name or text) to module/video/whatever

So your ProgramModules should be a map of string -> module, not a module itself.

Your module struct should then have a field that's a map of string -> video

i can show you an example in a sec

[open wadi]

@arctic horizon I would appreciate that, thank you.

It appears there are others who have attempted to search a struct by field name: https://forums.unrealengine.com/development-discussion/blueprint-visual-scripting/98178-get-struct-field-by-its-name

[arctic horizon]

it's like trying to search a struct in C++ - BP structs are analogues to structs in C/C++

you can't do it

what you want is a map

[open wadi]

I need nested maps, yes

What they call "hashes" in Ruby or "objects" in JS

But

[arctic horizon]

maps are supported in blueprint

[open wadi]

Right, and I'm using maps within this struct.

The reason I'm creating these predefined structs is because the data is static, it's not tabular so there's no need to use a datatable.

So I figured I would declare a struct, set the data, and use it as needed, basically akin to global constants.

[arctic horizon]

so here's what your module struct should look like:

your video struct is fine as-is

[open wadi]

Oh, I see how I screwed up

I set the keys as the video struct.

The keys are meant to be strings.

Yes of course, thank you siliex, very helpful.

[arctic horizon]

and this would be your ProgramModules variable

👍

you can then use "Find" on your ProgramModules variable.

[open wadi]

Terrific, that was the missing piece. Just a dumb mistake declaring the keys themselves of the video struct.

I'm hellbent on completing this entire project in Blueprints so I finally master GUI-based IDEs like this, since I greatly prefer CLI-based code, so it's useful to learn all these from a BP standpoint.

[raven elm]

Hey all, Im basically not at all good at UE4 but wanted to secure a sure-fire development/port workflow from Blender to the engine to know I can for sure make my projects. Im quickly realizing how difficult it is to do this but I wanted input if this is too ambitious for one guy

[autumn elbow]

Probably a stupid question, but is it possible to reference a Unreal project into another? Sort of like a module thing.

[worn granite]

closest thing to that would be a feature/template pack or perhaps a plugin

[autumn elbow]

Say I have a uproject with my character, and I want to use that in another project, but I'd like to keep a live link

A plugin that's a entire project?

an example would be how references work in Maya or Max.

There's no reason to do it... I'm just thinking 😂

[open wadi]

@arctic horizon I have the same fundamental issue though. I can't determine how to search the keys for a key that matches a string.

I have converted the Modules struct as you specified - the keys are all strings.

[autumn elbow]

@open wadi get keys

[open wadi]

Get keys, ok, let me try that.

[autumn elbow]

Will give you an array

[open wadi]

I do not have a node available, even without context sensitivity, that contains just the string "get keys"

[autumn elbow]

Keys

[open wadi]

The closest thing I have is "get keys from string table" which is not compatible with my variable.

[autumn elbow]

Well.. you have a MAP right?

[open wadi]

Keys is not compatible.

[autumn elbow]

Sorry, I just jumped in here... what are you trying to do?

[open wadi]

Here, let me copy / paste the description.

[autumn elbow]

Kk

[open wadi]

I have two custom structs: Module and Video. The logic is, I have multiple modules, each of which contains multiple videos. Therefore, "Video" is a series of strings for URL, Name, Title, etc. Module is a map of Video. Therefore Module1 => Video1 has the properties URL, Name, Title, etc.
For example, here is my Module struct.

Pretty straightforward. It's literally how you would declare a variable in a language as rudimentary as Javascript as ProgramModules => { "Module1" => { "Video1" => { "URL", "Name", "Title" }, "Video2" => { "URL", "Name", "Title" }, "Module2" => { "Video1" => { "URL", "Name", "Title" }...

In my Blueprint, I simply declare a single variable: ProgramModules, and set the type to my custom Module struct.
That's all well and good, except for the fact that I cannot find any example of how to iterate or search for keys or values within this variable.

All the typical Map search operations: Contains, Find, etc, do not seem to work properly to search for keys by name. I'm happy to For Each Break over it, but I can't even determine how to, in this case, do such.

So for step one, all I want to do is, within this ProgramModules variable, be able to search the keys for a specific Module name.

I've even tried wacky things like converting the struct to a Json object using the SocketIO library, no dice.
Surely there is a way to do this within a Blueprint.

-=-=-

At the end of the day, it's fairly simple: I have a struct, Module, and each key within this struct is a string, and it is mapped to my other custom struct, "video"

There's my struct. I declare a variable, ProgramModules, of this struct.

I just want to search the keys within ProgramModules to see if myStringVariable matches the key name "Module1", or "Module 2", so on and so forth.

I take it by the silence we don't know this one either.

I can easily split the struct and run find operations on each individual "Module1", "Module2", etc map.

[autumn elbow]

k.. reading

[open wadi]

But that doesn't allow me to search the struct fields themselves. When I say "keys" in this context, I believe the proper term is "fields". My Module struct has 3 fields right now: "Start Here" (map to Video struct), "Module 1" (map to Video struct), and "Module 2" (map to Video struct). I need to be able to search the struct field names, if that term is right, to see if a string in my function matches "Start Here", "Module 1", or "Module 2".

[autumn elbow]

ok.. so... you have a MAP... the keys are strings? and the values are structure , correct?

[open wadi]

Or is the proper term in this context "struct members", I don't have a clue.

It's exactly how it looks in that screenshot

That is the struct

[autumn elbow]

You have 3 layers

[open wadi]

Yes, I believe the way you stated it is correct: the keys are strings, the values are the video struct, but the video struct isn't even an issue now.

All I want to do is search the struct key names, if that term is right, for a match.

[autumn elbow]

You have a map of a map

[atomic viper]

would anyone know how to bring in a third person actor/class/blueprint into an already work in progress shooter game?

[autumn elbow]

So, droptone, can I see you top level Map?

[open wadi]

Thor: What I'm essentially trying to do is replicate what you would write in Ruby or JS as ProgramModules = { "Module1" => { "Video1" => { "URL", "Name", "Title" }, "Video2" => { "URL", "Name", "Title" }, "Module2" => { "Video1" => { "URL", "Name", "Title" }...

What top level map?

There is no top-level map, I simply declare ProgramModules of the type of that struct I showed in the screenshot

This here. A variable, ProgramModules, is simply defined with datatype set to this struct.

There is nothing above it.

[autumn elbow]

Yea, yea.. I get I know what trying to do.

[open wadi]

Good deal.

[autumn elbow]

You basically have 3 layers. You have a Module, then video, then video data.

[open wadi]

Right, and right now all I want to do is search the fields / keys where you see "Module 1", "Module 2", etc, to see if a local variable within a function matches that name.

I don't even care about the videos below.

If I can figure out that part, I can handle the rest.

[autumn elbow]

ok.. can I see your MAP variable? in ur bp editor

[open wadi]

I mean, it's just a variable declared of the type of the struct in this screenshot.

But yes, one moment

[autumn elbow]

Ya.. not the struct but the actual MAP node

[open wadi]

Well I can break out the struct within a BP to reveal the individual Start Here, Module 1, and Module 2 maps

Here it is unsplit:

[autumn elbow]

ok, so pull ProgramModules in your bp graph

[open wadi]

Here it is after selecting "split struct"

[autumn elbow]

Ok, hmmm..

[open wadi]

It just reveals the individual maps within the struct

[radiant jasper]

LMAO i found a game i made when i was like 11 years old

its so horrible i hate it so much

https://gamejolt.com/games/barf-man/144847

[open wadi]

And this is the dilemma: I need to search the "keys" themselves

[autumn elbow]

Gotcha..

[open wadi]

And that begs another question

The terminology: Am I using this correctly?

[autumn elbow]

Let's do this another way

[open wadi]

Would, in this context, "Start Here", "Module 1", and "Module 2" be considered "keys", or "fields"?

Or something else?

[autumn elbow]

Yea.. you want the modules to be Keys

[open wadi]

Since they're struct variables

So that I don't confuse people.

And yes sped thank you for sharing the game you made when you were 11, quite a gem.

[autumn elbow]

so you can search Module1 , and get a list of videos

[open wadi]

Right

But even then, that presents an issue.

So fundamentally, the reason I need to search is because I'm writing a BP function where "Module" and "Video" are passed as params

The modules and video data are static, akin to global constants- they don't need to change during the project.

[autumn elbow]

ok...so let's do the keys thing first.

then we can look at the other layers

[open wadi]

So I need a variable datatype where I can search for the proper module, and then, from there, find the proper video within that module.

That sounds fine Thor, I"m certainly open to any suggestion.

[autumn elbow]

so, right now.. ur modules is a struct... which is incorrect

It needs to be a map

[open wadi]

Right, I just need to be able to have them in some related form, ideally in one proper variable.

Or constant, since they don't need to change.

That way, when I pass "module 1" and "video 2" to the function

I can execute a search for the proper module, then the proper video within that module.

[autumn elbow]

So just so we don't mess anything you already have.. make a new variable, call it ProgramMod2 or something

[open wadi]

What datatype?

[autumn elbow]

it's going to be a MAP, of String and Modulstruct

[open wadi]

Ok, interesting.

Just to be clear, should it not a map from string to the custom video struct?

Are we basically going to replicate the current module struct functionality within a variable?

[autumn elbow]

oh sorry... yea.. whatever your video struct is called

[open wadi]

Right right.

Done.

That's the video struct on the right.

Program Video is what it's called.

[autumn elbow]

Ok.. give it a try... you should be able to put in "module1" and get a list of videos

[open wadi]

Great, so basically, just dynamically create this instead of placing it within a struct. Now, the $64,000 question: Can I search this variable's "string" properties to find out if myParam matches ProgramMod2.whatever?

so if I create ProgramMod2.Module1, ProgramMod2.Module2, so forth (so to speak), that's the root issue I need to tackle. I need to be able to search the key names of this variable for a match.

[autumn elbow]

ok.. so your MAP is correct though right?

it's giving you the correct info

[open wadi]

Well, using this route I would have to create a different variable for each module.

[autumn elbow]

What do you mean?

[open wadi]

Because it's string > program video, I can simply put in Video 1 => URL, Title, Name, so forth, then Video 2 => URL, Title, Name, so forth

As the map elements.

Therefore, I would have to create a unique variable for each module.

[autumn elbow]

it's all within that one map

[open wadi]

I would have to create ProgramModule1, then, as the map elements, set "Video 1" > Title, URL, etc

Example.

[autumn elbow]

That's looks correct

[open wadi]

You know what?

I could use this route, but simply not have the separate "modules" section

Ok, I have an idea of how to make this work.

[autumn elbow]

So skip the modules, and just have videos?

[open wadi]

Yes, I already added a redundant "Module" int param to my videos struct

Then it will just be a normal map

[tired lynx]

hey does anybody know where the movie render queue is located in 4.26 preview 2?

looks like it's been moved from window > cinematics

[autumn elbow]

Sure, if you want to search the video by name, then ya

[open wadi]

Which presents another unique issue: So say I do that. Say I simply have ProgramVideos, and the videos have a param "Module" like they do now, and I set the first 5 videos to "0" for the first module, then the next 5 videos to "1" for the second module, so forth.

That's great, except, when I need to search the variable by module, I'll need to extract all the videos that have a specific module setting.

So if I pass the parent function "The video I need is video #2 from Module 0"

How would I write such a find operation with a normal map?

So never mind, I don't need to extract all videos with a specific Module ID set

But I need to be able to search "find me the video in this map that has the module ID set to 0 and the video ID set to 2"

How would that be written in BP?

Basically a find operation with 2 parameters instead of 1

[autumn elbow]

if you need 2 sets then you need the route you had before. Module1-> video1,video2 etc

[open wadi]

Please note this data is a constant, it isn't changing.

Well the route I had before is apparently impossible to search by, at least the way I had it.

No one can find a solution and someone previously said you cannot search field names in structs.

Perhaps I could use a nested foreach break loop

[autumn elbow]

Hold on... I'll show you .. my Unreal is booting

[open wadi]

Brilliant.

You figure this out and I'm naming my next child "Thor-bie" regardless of sex.

I've spent a day on this shit.

And the bigger issue is that I'm going to have some two dozen "program videos" and I need them in a single variable so I can search for the proper one, not endless strings.

That's why I started using custom structs, I basically use them as global constants for static, predefined data.

That's been working well in other cases, but in this case the added layer of the per-video metadata being indexed by modules broke the format, since I can't"find" by the keys / field names themselves within a struct, I can only select a given struct key / field and find within that.

I'd also like to let the record state that this would have taken two seconds in a CLI-based language.

Ok, so if I simply have all videos in a single map, and the videos each have a ModuleID and VideoID field, I could do this: Get all values from the map, pass them to a for each w/ break loop - then, the last question becomes, how do I check to see if the value the loop is at contains "ModuleID" == 0 && "VideoID" == 1?

[autumn elbow]

ok im up to here

[open wadi]

Watching video

[autumn elbow]

now I will build the search string

[open wadi]

Ok, great, that's printing the keys.

Yes, see if you can get the values and pull "ModuleID" and "VideoID" (what I renamed the ints Module and Order to)

Example

This way I can have everything in one map.

I just give each video a ModuleID and VideoID

So I just need that for each break to find "which value in the map has ModuleID == 0 and VideoID == 1, for example

[autumn elbow]

so the search string will be Program.ModID.VID ~ Program.Module1.Video1

[open wadi]

Well I got rid of the extra "Modules" layer completely

So now, it's nothing but Videos, and each video has a ModuleID and a VideoID

So I need to just find, in this single map, which value has ModileID == 0 && VideoID == 1

For example

[autumn elbow]

hold on. i'll make it and then we can change it to fit how you want to search for it

[open wadi]

Great

Any luck?

[autumn elbow]

ya.. making the strinf thing

[open wadi]

Good deal.

[open wadi]

@autumn elbow Any luck?

[autumn elbow]

done

@open wadi

[open wadi]

Checking

Ok

@autumn elbow If I have a map of Videos, with two parameters: ModuleID (int) and VideoID (int), how do I find one that matches ModuleID == 0 && VideoID == 1?

[autumn elbow]

how are you inputting the module and id

[open wadi]

It's in the Map

They're just video params

[autumn elbow]

in the video i supply the module and video and i get the data

ok.. so the ID in your pic is apart of the data

[open wadi]

Right

Let me check that video again, perhaps I missed something

Oh wait

Well never mind, the video was cut off on my other machine.

Well good heavens, you actually nested them.

I'm trying to wrap my head around what you did in this video.

No this video looks fine.

[autumn elbow]

ok.. so this is what you wanted ?

[open wadi]

So your "GetVideoInfo", you split the string

Which is just the param you pass to the function

Then you run a find operation on Program, then from there another find operation on video

So the question becomes: What does your SModule datatype look like?

[autumn elbow]

https://blueprintue.com/render/959uic1f

[open wadi]

Right

But your variable type that allowed you to have nested maps like that

Your "Program" variable is a map of String > SModule

What does SModule look like?

Where do you delcare that?

[stone oar]

uh I need some help with meshes

it's a static mesh, I just wanna move it so it's centered on the origin

[autumn elbow]

@open wadi

[open wadi]

Wow, so what the hell? You set it up exactly how I had it set up initially

And you were just able to run two find operations on it?

[lyric sundial]

Hey guys, I have a question regarding UE4 custom collision.
I have a semi-complex spider mesh that I'd like to make it fully collide-able.
However, all I could find on the internet was to make individual colliders and manually attach them onto sockets of the skeletal mesh in the construct script. It seems really tedious and time consuming.
Is there a way to apply the simple collision settings to this non-static mesh?
I also saw people mentioning creating a custom collision in the modelling software... But I don't have any modelling knowledge so I have to rule out this option. 🙁

[open wadi]

I see, so what you did different is when you created your program var, you declared it a map of string to your module type

Which I believe is one of the very first things you suggested, lol

Well slap my ass and call me shirley, that's fantastic.

[autumn elbow]

lol

Make sure that baby is named Thor

[open wadi]

Let me just confirm this real fast, spectacular work.

Thor specifically, you got it.

[autumn elbow]

😂

[open wadi]

My existing two children might find the name odd but I give zero fucks.

They'll have to deal.

Ok I'm testing this on my end.

Ok, hmmm

Ok so I see.

One redundancy you have is in your default value of that var, your hierarchy is Program > Module1 > Video > Video1, Video2, Video3

But I suppose that allows you to execute these find operations

[autumn elbow]

Thats just how MAP lists them

[open wadi]

Oh, ok

The reason I was using predefined structs is so I could declare the static data there, akin to a constant.

So would it be fine to define all the module and video data in the structus?

[autumn elbow]

you can see in the find... im not doing Module>Video>Video1. I'm just doing Module>Video1

[open wadi]

Yes, the find operation looks normal, it was just that "default value" section

[autumn elbow]

yea, its just the display

[open wadi]

Right.

Ok, well hell, I'll need to build this out but brilliant, this should work perfectly.

Tremendous work, thank you.

[plush yew]

guess none knows how to fix my error?

cause now i lost my project ;/

it worked thank you a lot @quick kelp

[quick kelp]

@plush yew just read your error, i have a solution though it might not be the best

go to the project folder location on your computer and just delete the folder of the assest you imported

every market place asset adds a folder inside the content folder of your project

if its the market place asset causing the error, then deleting it will allow your project to launch again

[plush yew]

i did that

i deleted the config stuff and it worked but now my blueprints have errors and so on xD

so im gonna try it on 4.26 preview

but it only happened once that asset was put in

well i only deleted the engine ini file

[quick kelp]

i had a similar experience before where an animation blueprint kept crashing UE4 whenever i opened it, solution for me was delete the animation blueprnt from project folder, backup the project into another folder, delete the project from epic games store launcher, then open it again from the backup folder and that fixed it.

String operations are significantly more taxing

Some int / 10 pretty much always results in the same int, just having the last digit removed

[harsh tiger]

Like 60 / 10 would be fine. But its when i get any number that doesn’t end in 0, that might give me some issues

[dense gate]

It won't

Ints don't have a floating comma

It's like the math you would've learned in like elementary school

10 / 3 = 3 (and 1 remainder)

[storm iris]

How can I make a rock that is a static mesh impenetrable?

[dense gate]

its the area u can use to skulpt or flatten or stuff , @ your land

@pearl mortar

klick on modes - select , to get your mouse back

[opal carbon]

nice I'm actually really happy to see that there's an unreal engine discord server

[worldly comet]

If you're having collision issues, make sure the asset is set on generate collision on the import settings, a bit more expensive approach would be to model out your own collision mesh and export that with the asset and set to not generate collision on import and under collision settings set to custom.
If you need to know more,, YouTube is your best friend.

[plush yew]

how can i move all my keyframes in blender to end at 30 fps so i can get my animation to unreal engine ?

i found out

[opal carbon]

oh yeah I had a question about collision actually

what's the best way to export blender models with collision with the geometry to save me time?

like if I made a huge hospital or something, how would I export that with collision in the walls automatically?

[worldly comet]

Have collision automatically generate upon import in the import settings before you confirm import or import all

[opal carbon]

unfortunately, that just makes the entire thing so you can't walk inside it

[worldly comet]

https://youtu.be/ksGmbDM2mNU

[opal carbon]

I mean I've just been adding a bunch of invisible walls and it works fine tbh

[worldly comet]

This walks you through creating a custom collision

[opal carbon]

ok

I'll save that for later, probably a future project

[worldly comet]

The mesh isn't so important as the naming of it.

[opal carbon]

isn't it the UCX_(model_name)

?

[worldly comet]

It's been quite a while but it think it has to have the exact same name as the mesh It's a collider for but with the suffix UCX

[opal carbon]

yeah I was reading something that you had to parent a mesh to the mesh with UCX_

[worldly comet]

I don't believe I had to parent them, just export them in the same fbx

Parenting may cause issues

[opal carbon]

oh really?

that might be why tbh

but like if I copy and paste the same model in the same position, will the collision just be set to anywhere the model has a wall?

How do I get my lights to stop pulsing and just stay dynamically lit?

it pisses me off when I do that

[void mirage]

Can anyone help me with a question

I'm sorry to just jump in but I have questions and they are probably stupid but I am new to making game creation like out of the box new am I allowed to use Market place items like the free ones in the development of my VR game or are there restrictions or conditions or are they place holders . I dont wanna get in trouble for using something that I'm not allowed to

[opal carbon]

ah same I just started too tbh

I think you should be good using them

but check what CC license they have

or what license in general

if it says "attribution", you might have to credit them

all of my assets are either custom made by me, or CC0

[void mirage]

This is the subject I need to hear

[exotic thicket]

Marketplace content is allowed to be used with Unreal Engine based projects

No restrictions.

[opal carbon]

oh wait actually

[void mirage]

Perfect

[opal carbon]

hold on

[void mirage]

...

[opal carbon]

you can't sell the game for money if you don't own a professional license from epic

[exotic thicket]

The license for marketplace content is available somewhere on the UE website if you want to check the more specific terms

[opal carbon]

that's really important actually

[exotic thicket]

afaik you get a license basically by telling them you're selling a game and then just need to report sales figures so they know if you go over the 1 mil revenue limit :)

[void mirage]

Can some one go into more detail with this subject with me my project revolves around blueprints and idk if I wanna make money or not I downloaded the copy of unreal where if my game is successful I have to pay 5% or something

[exotic thicket]

https://www.unrealengine.com/en-US/faq

check there

The cliff notes version is that if your project makes more than 1 million USD in revenue you need to pay 5% in royalties. Otherwise nothing

[opal carbon]

yeye so like deadmau5 will obv be paying more 5% in royalties in oberhalsi XD

for*

not in

[void mirage]

So if I make a vr game and use some free assets from the market place say like grass landscape vol.1 do I get in trouble for using there asset in my game if I make money off a game ....?

[plush yew]

how do i transform animated cube into unreal engine 4 from blender ?

[exotic thicket]

@void mirage no. You never need to pay anything for marketplace content (other than if you needed to purchase the content).. the 5% is only payable to epic if you make more than 1 million USD lifetime revenue from your game

[opal carbon]

@void mirage check what the license for the assets are

oh ok cool

yeah I haven't been using marketplace tbh

the files are too big tbh. I've just been using low-poly assets because I like that style anyway lol

[exotic thicket]

this page has the licensing info for marketplace content https://www.unrealengine.com/en-US/marketplace-faq

[opal carbon]

hey how do I paint colors onto the landscape?

trying to make a parking lot :p

nvm

but how do I uhh use rgb/hex values as a texture?

[thick herald]

https://learn.unrealengine.com/home/dashboard

[opal carbon]

I mean I don't want to have to read through the entire thing to learn one thing

it's fine I'll just use a picture of yellow ig

[covert hedge]

parking lot? just find some concrete texture and some road line decals

[opal carbon]

nevermind I already finished it

[pearl mortar]

Guys what is this and how can I fix it?

Im trying to paint my landscape

the second image shows a filled layer with same texture

the first image should be completely black but it has strange things happening

[errant mist]

Does anyone knows how i can use my switch controller inside Unreal engine because for me it dont work?

[opal carbon]

switch controllers aren't PC compatible without some drivers @errant mist to my knowledge, at least

and yes, I know you're not talking about joycons

also here's the neat lil parking lot I made

[errant mist]

@opal carbon do you have an good emulator?

[opal carbon]

uh I don't use pro controllers on PC

[kind temple]

Okay I am breaking my mind over this one . 2.5D scroller . when I I start the game the characters back is facing me . I want him to face forward. I turn the start gameStart arrow to face the character then mey A D key's are inversed

Below gif A goes left and D goes right which is correct .

[opal carbon]

I'm pretty sure they aren't PC compatible without a lot of reworking

[errant mist]

They work on Steam

[opal carbon]

idk what to tell you then

you should do some research and see what drivers you need

[errant mist]

no emulator only plugin the usb c cable

ok thx man

[kind temple]

Below Gif D goes left and A goes Right . whitch is wrong.

[thick herald]

That isn't wrong, you have it set up to when the player presses A the character moves to their left etc.

[kind temple]

Nope. Then I push D the character moves Left

not right

but I switched the input values in the input for now and that fixed my issue

[worldly comet]

Just out of curiosity, what if you flipped your camera to the other side??

That works too

[kind temple]

Nope

Tried everything before asking .

I want the character to face the camera. If I turn the mesh in the the game world or the viewport in my BP_Base viewport it inverted my A and D keys . The only way I could have the mesh face the camera when clicking start and having him walk right when pushing D and left when Pushing A is invert the Positive and Negative in the Project setting Input tab

I'M going to be Asking a Metric Ton of questions in here in the next coming months. I do however Try and google and try figure it out before asking .

[pearl mortar]

Guys what is this and how can I fix it?

I need to load assets per level and need to unload all the level Once we change level

or may be in between

[opaque pasture]

what videos do you suggest to a complete beginner?

[plush yew]

is there any easy way for pawns to stay a minimum distance from eachother?

like a surrounding radius function? my bots fight and end up trying to make out instead of shooting from afar

anyone have any idea why my tcp socket wont close? im using FTcpListener to set it up. i can connect to it just fine from my c# app, but after i stop and exit the FTcpListener it still shows its open

nvm solved using FSockets

[vagrant hornet]

i feel ue4 ui is outdated

[exotic thicket]

how so?

[hard quarry]

Hi guys, just a quick question.
I received this uv map. Unreal Engine shows me some red parts, so I wanted to ask if this is fine or if this could lead to an error?

[sterile tulip]

Is my pc´s ram not enough or why do I get this message

[exotic thicket]

there's a setting somewhere for texture streaming pool size which you can increase to get rid of it

but not really sure if it's recommended or not, I'd assume it relates to VRAM amount or something

[sterile tulip]

is it hardware related or software? Is it because my pc is bad? I only have 2gb vram. Maybe its because my vram?

[exotic thicket]

I don't remember what the default value on the setting is... I know increasing it got rid of the warning in one of my projects

at least it should be worth a try

[fervent sigil]

@sterile tulip I just dealt with this today. First suggestion online was to use stat Streaming, although personally I couldn't find anything useful in there.
I used list Textures though, which lists all textures and the size they take in memory.

Personally I was loading a big tiled landscape in memory, and list Textures told me a lot of heightmaps were taking memory. Since I knew it was fine,
I simply increased the pool size. But you'll want to verify it is fine.

Also note you can go to Build -> Build streaming pool (or something like that). it can help.

[sterile tulip]

If I had a bigger vram and ram, would this same problem occur aswell? Or is it not on my hardware related?

[fervent sigil]

The message is saying the textures that are loaded into memory are bigger than the pool (the memory it dedicated) for it.
The default is 1000mb, and I'm pretty sure it's not hardware related it's the same regardless of your hardware

just to compare, I got 32gb memory and 8gb vram

[sterile tulip]

hmmm

I googled and it says you can increase the texture streaming pool and make it bigger

[fervent sigil]

Personally I was loading a big tiled landscape in memory, and list Textures told me a lot of heightmaps were taking memory. Since I knew it was fine,
I simply increased the pool size. But you'll want to verify it is fine.
Yeah like I said

[neat forge]

Is it expensive to use an array of structs?

[sterile tulip]

The pool size is it taking up its memory from VRAM or RAM? @fervent sigil

[fervent sigil]

@neat forge More expensive than not using it

@sterile tulip RAM

[sterile tulip]

How much did you made your pool?

[fervent sigil]

Actually, I'm not 100% sure. Let me see if I can verify that.
And I increased mine to 2000mb btw

[neat forge]

I am wondering because I'm making a friends list in my game, I can do one of two things, either cast to game mode to get a players friends ID and then fetch their data from there, OR I could store the players data in an array struct that is stored in the player who holds the friend list

Which do you think it's more efficient?

[fervent sigil]

@neat forge I believe you're talking about multiplayer, you're probably better off asking there. But as far as I know that info should be inside Game State; it's a class that is replicated to both clients and servers. This should help: http://cedric-neukirchen.net/Downloads/Compendium/UE4_Network_Compendium_by_Cedric_eXi_Neukirchen.pdf

@sterile tulip My bad, it's vram. Note however I was loading a lot of textures in memory, and not something that usually happen. so 1gb should be more than enough.
Which is why I suggested first seeing why all the memory is being used and if you really need to enlarge the pool or unload some textures from it

[neat forge]

Thanks I'll check that out

[sterile tulip]

If I have 8gb vram, can I increase the pool to 8gb?

[fervent sigil]

Increasing your pool won't use my vram :p

[sterile tulip]

yes I mean mine

[fervent sigil]

yeah I was j/k. Probably not btw, your pc is probably using some vram

[sterile tulip]

hmm

[fervent sigil]

I'm on windows 10 and there's even a metric for it in Task Manager. With my editor closed, I'm using around 0.7gb of dedicated gpu memory

[sterile tulip]

But if I have 8gb of vram, I can dedicate 5gb I think

[fervent sigil]

probably. But you really shouldn't. Don't forget about the people who will use your game too btw; I doubt most of them have 8gb of vram. That's a high-end pc

[sterile tulip]

Why does it not use all my vram on standard? If I dont increase the streaming pool, will it not go over 1gb vram? Because the streaming pool is standard at 1gb?

[fervent sigil]

yes. The default is at 1gb for low-end pcs which doesn't have much. from what I know an app can easily crash if you try to overload it with too much gpu memory, and that's the best case scenario.

[sterile tulip]

so I should dedicate to texture streaming only as much as it needs

prob increase pool size to 2gb if 1gb is not enough

[fervent sigil]

1gb should be enough

[sterile tulip]

mine is capping

[fervent sigil]

@sterile tulip I just dealt with this today. First suggestion online was to use stat Streaming, although personally I couldn't find anything useful in there.
I used list Textures though, which lists all textures and the size they take in memory.
do that

[sterile tulip]

I havent even loaded much

[fervent sigil]

the 2nd line specifically

[sterile tulip]

I used foliage

But I dont wanna remove my foliage XD

[fervent sigil]

Is that what the list textures says? perhaps the textures for them is too big and doesn't have mips or something like that

I had huge fields of grass and no warnings about texture streaming. You should probably check into that

[sterile tulip]

increasing pool size by 1gb means everyone playing this game will also use 1gb more vram?

I think I will increase the pool size if thats possible only for the ultra quality, and for the low graphics settings I will lower the foliage and set pool size back to 1gb

so the people with more vram can play with more pool size and others with smaller one

[fervent sigil]

from what I understand the pool size is only a limitation in the editor. It's not even a limitation as you can see btw, it's just a warning.
So anyone playing the game will require the same amount of vram as when you're playing it, yes. It can differ in the editor, but mostly dependent on the pov

Hi all, I have read the tutorials for UGC Mod Engines.
Now I would like to follow along:

it refers to needing a "Source Build of Unreal" < Does this mean downloading the GitHub Source and compiling it yourself?__ Is there a tutorial?__****

[atomic viper]

would anyone know how to create ENEMY AI? I'm trying to use the paragon assets for my project

[thorn scarab]

@atomic viper use google. bunch of tutorials on youtube. like too many

[vale egret]

@atomic viper https://learn.unrealengine.com/course/3318392?r=False&ts=637380245894117613
Introduction to AI with Blueprints

[thick herald]

@foggy shuttle and @fervent sigil The kite demo can be found via the Launcher, in the Learn tab. 🙂

[atomic viper]

thanks, like I created a first person shooter game but I kind of added my own enemies (there just basic spheres for now) but idk if its possible to replace those with the assets? Or do I have to create it from scratch?

[foggy shuttle]

@thick herald can t find it dude. Do I have to install an older version on the engine?

[thick herald]

It has nothing to do with engine version. It's found in the actual launcher

[atomic viper]

i tried looking for a YT video, maybe Im not wording it right because I cant find it, could be me just not wording it right

[fervent sigil]

@thick herald I thought so too, but there's no search in there and I was too lazy to go over too many pages. Couldn't find it on the first few though

[thick herald]

It's half way down on the page 🙂

[fervent sigil]

for me it wasn't

[thick herald]

@vale egret yup, source = git

[fervent sigil]

@atomic viper If you have an actor selected in the browser and one in the game view, you can right click on the asset and you have an option like "Replace selected object with <asset name>". So yeah, it's possible

[thick herald]

Are you viewing it via the launcher and not the website?

[fervent sigil]

@vale egret I wouldn't be so eager to use the source if you're new to UE4 though; it just takes a lot of time. (you might not be new though, just saying)

[atomic viper]

@fervent sigil what really? Like even if the actors/objects are completely different shapes?

[fervent sigil]

@atomic viper Yup. It will simply create new ones, set their positions accordingly, and delete the old ones. Not really a big thing

[thick herald]

You can replace anything with anything. Mostly. 😄

Whether it works is another matter of course 😄

[fervent sigil]

You can replace anything with anything. Mostly. 😄
@thick herald Except material instance with material :p that bite me a few times ><

[atomic viper]

yea, Im not worried too much with materials just the asset itself

[thick herald]

I would caution against using anything from the kite demo. They are not performant at all, and will likely cause you problems

[atomic viper]

So i tried replacing it and it uhhhh, didn't really work, some crazy things happened

That moment when you find someone on answers.unrealengine who has had the exact same problem as you do, and then later reads the name of the person and realize it was you who asked that question there a year ago...

[vale egret]

IKR!!!!

[shell compass]

Luckily, someone had helped me solve it back then, so I could easily apply the same fix this time 🙂

[vale egret]

I literally had that problem a couple years ago in Unity where I had a problem, looked up Stack Overflow, found the EXACT ANSWER i needed to get going... went to upvote the answer:

You cannot upvote your own answers

[shell compass]

lol

[vale egret]

2 years later the EXACT SAME THING happened again (yep, bugfixes dont really happen in Unity once there is a hacky work-around on Stack Overflow) and then I vowed to start writing a blog - for literally no other reason than "in 2 years time I am going to have the same question again"

[shell compass]

Probably a good idea. Except writing a blog sounds like even more effort than writing comments... which is also too much of an effort most days!

Any quick ideas on how to reduce freezing when background level streaming (loading) ? I have a "waiting" anim screen with a Niagara particlesystem running and it will freeze for upto 10 seconds while backgroundloading a map, the map is somewhat big but I wish I could get it to just use the time it takes to load without freezing or too much stuttering..

[shell hamlet]

guys I am not sure what is wrong, how do I fix this strange foliage placement ?

V4.25 - Megascan Assets

[fervent sigil]

how did you place the foliage?

@queen wasp I believe there is sync and there is an async methods for loading level, so look for that

[unique kraken]

hey couldnt you copy the folder path in ue4?

[queen wasp]

@fervent sigil thanks, sort of thought I was OK with async, but tried to tweak the values a bit, ended up with minimum size for async set to 1 and the ms set to 3 and 5, still getting a 7 second total halt in there but slightly better.. weird that it varies but slight improvement..

My impression was that it would load in background and enable me to have a smooth running anim in the foreground though

I also tried sync not async, not much difference hmm..

I can try profile and see if there's any info on the hang..

[plush yew]

Sweet heavens just fixed my 4.25 IntelliSense bug. I was about ready to install Unity.

[sterile tulip]

Is 4.26 the last update before UE5?

[queen wasp]

Am getting "CPU stall wait for event" in the 3-4kms over several frames

And pool thread "wait for work" ..it is halting the foreground waiting animation, what it is doing I have no idea..

[plush yew]

Unreal Engine 5 will be available in preview in early 2021, and in full release late in 2021.

[queen wasp]

All I know is that players would feel better about a smooth running waiting anim, than a long freeze, quality wise..

So, I just want to try fix it 🙂

[plush yew]

I wouldn't be surprised if there are more UE4 patches, but they'll probably halt feature development shortly after 4.26.

would anyone know why when I replace an AI with another mesh, it doesnt behave properly? like it goes out of control

[queen wasp]

Anyone has any idea how the Materials Expression Landscape Layer Blend works internally? I am trying to recreate it outside,, with exported layerinfos reimported as textures and using worldposition for coords. Basically I have a shoreline consisting of some construction generated Instanced Static Mesh actors, and their material needs to (hopefully) match the landscape. I got it semiworking but with eyeballing and tweaking.. I just wish I knew the right formula to recreate the blending in a non-landscape material.
