[open gorge]

you can just create a new blueprint class

and base it on your custom game isntance

sec i'm mid build

i'll take a screenshot in a sec

[alpine laurel]

i am trying to use steam advanced sessions and that requires a blueprint game instance, but my game instance is c++

thanks

[lucid socket]

Why would it require a BP?

[alpine laurel]

the tutorials i have found have all been in bp so

[rough knoll]

my unreal is still freezing my pc when i package

[open gorge]

advanced sessions and steam advanced sessions are blueprint only function libraries @lucid socket

through the use of proxies

[rough knoll]

i have no idea what to do at this point

[lucid socket]

Sure, but it'll be implemented in C / C++.

[rough knoll]

the only option i see is buyin more ram and then i wont be able to package it for a few mor days

[lucid socket]

So you should be able to just call those functions.

[open gorge]

@rough knoll ?

is it a specific error?

or just freezing?

how are you packaging?

in editor?

[rough knoll]

@open gorge when i package my game halfway through shader compiling the whole pc freezes

yes

it uses 99% of my ram and i assume thats why

it doesnt freeze my pc until it gets to atleast 97%

[open gorge]

what are your specs?

[rough knoll]

i7-4790k, 12gb ram, rx 570

[open gorge]

yeah

that's not a RAM issue

give me a minute

I have a solution for you

[distant totem]

@rough knoll this community has helped me out immensely, if you want, and your comfortable, you can send me the project and I'll send you a packaged version back, you can even see if you can find a free NDA template if you want

[open gorge]

I was just going to send him a command to run in cmd to package that way

[distant totem]

try his solution though for sure

[open gorge]

since that's all packaging does

[rough knoll]

ill definitely try it

[open gorge]

@lucid socket if you're working in C++ then you should just call sessions normally.

Advanced Sessions was designed purely for BP

[rough knoll]

if it doesnt work im cool with that @distant totem, all it is is an alpha i want to give to my friends to playtest and find bugs

[open gorge]

and the functions aren't callable in C++ directly

@alpine laurel 3 Steps:

1. Right Click in Editor and Select Create Asset -> Blueprint
2. Click the drop down for all classes and type the name of your Game Instance c++ class in that field.
3. Select it and click ok.```

i'm using my test controller as an example

[lucid socket]

OK.

[alpine laurel]

how does that apply to my game instance though?

[open gorge]

Blueprints are just child classes of C++ ones

or other BP's

which are children of C++ classes

etc

it's all inheritance

[alpine laurel]

oh ok

[open gorge]

so if you create a function in C++ like this, it will be usable in blueprint:

[alpine laurel]

would i just copy paste the other gameinstance code into the c++ .h file of my new instance?

still not clear on that aspect

[open gorge]

What other game instance code?

[alpine laurel]

okay so my main game instance is in c++, but for my steam advanced sessions to work i need to have a game instance in blueprints. i am trying to figure out how to get the blueprint gameinstance to also have my c++ code from the other gameinstance

[open gorge]

what is this other game instance?

that doesn't make any sense

also make sure you set your project to use your custom game instance, in Project Settings-Maps & Modes (at the bottom)

[alpine laurel]

yeah im doing that

see i have the c++ clas instance and there is the blueprint one i have open in the second image

[open gorge]

yup

what's the issue?

you see on the top right of your BP

how it says Parent Class?

[alpine laurel]

yeah i already figured it out

[open gorge]

😄

[alpine laurel]

im too tired to be working on this. im going to bed. thanks for putting up with my stupidity

[open gorge]

it's all good

we all start somewhere

at least you learned something

[solemn siren]

Hey Everyone! 'm not sure where this question goes, so posting it in this channel. Has anybody worked with pype or Avalon for UE? I've seen their documentation and all but didn't understand much. It would be really helpful if someone can just tell it to me in simple terms what they do and what are they used for.

1. Pype connects asset database, project management and time tracking into a single modular system.
2. Avalon with Pype provides a safe and stable technical backbone for your studio, without the worry of a vendor lock. 

I've used UE4 for a while but still consider myself a beginner.

[open gorge]

what are you trying to use them for?

afaik Avalon is a programming language?

[solemn siren]

Just trying out things. I don't intend on using them yet.

[open gorge]

right, but what's your end goal?

[solemn siren]

Learning, I guess. I'm just discovering different tools. No end goal as such

afaik, Avalon isn't a programming knowledge
https://getavalon.github.io/2.0/

[open gorge]

The Avalon Programming Language is a statically typed language based on algebraic data types. It features type inference for variable declaration when the compiler can deduce the complete type. With extended overloading, it gives users the ability to create more powerful functions that are intuitive to users.```

lol

it is

[solemn siren]

oh

[open gorge]

but that particular tool is mainly python

I've never heard of it before

Pype should have given it away

I thought it was just a weird term for Pipe

[solemn siren]

I think both Avalons are different

[open gorge]

they are

but from what it looks like, Avalon is just a tool that helps organize file structures and asset formatting for artists.

Mainly with Maya

that's the gist I can get from browsing a bit

[solemn siren]

Okay,

Global production pipeline

What's that supposed to mean?

[open gorge]

honestly

looks like buzzwords

for marketing

and SEO

[solemn siren]

lol okay XD

[open gorge]

Production Pipeline makes sense

that's how an asset goes from concept -> in game

or publish

Global might mean a standard in this case

¯_(ツ)_/¯

[solemn siren]

But isn't pipeline just an idea of how we're supposed to progress? Why do we need a software for that?

[open gorge]

pipeline isn't a software

pipeline is the standard of how you get from A->B

There are several studies into standardization and the benefits of it

[plush yew]

i mean most software is used to realize pipelines.. so

[open gorge]

especially in cases of assets

that's true as well

[plush yew]

i have hundreds of mini pipelines on google docs. just a series of notes and paradigms for tasks. usually i have them assigned to common tools like unreal or blender etc.

otherwise there's no way to proceed really

[open gorge]

i keep mine mentally, but yeah same things

it's like using a tracking board like trello for tracking tasks has proven to be worth the time it takes to do it

[plush yew]

imo the common pipelines for foss software works best

[open gorge]

and improves productivity

[plush yew]

i have a trello. pretty broad strokes though.

in any case i'm glad unreal 5 will be easily compatible with the current ue versions 🙂 such a relief it's not some totally new tool

talk about pipeline integration.. there you go

[solemn siren]

So pype and Avalon are something that helps keep track of assets, deadlines, etc? Just to keep the whole team together I guess. 😬

[open gorge]

Avalon uses Pype, which is a python tool or library

at least as far as I read about it

but, Avalon's goal is to standardize file structures and asset formatting

it says that in it's first post

back in Jan

[solemn siren]

Understood, ig, Thanks!

[sudden oriole]

How do I get motivation for making a game? I really want to make games but I never get the motivation to do so. Maybe it is because of my lack of knowledge? I don't know.

[dire fjord]

So if I have engine plugins that i need to share with the team, I need to move those to the project plugin folder so that they're included in the repo right?

[solemn siren]

@dire fjord aren't they already there? If you made the Plugin, then yes.

[balmy tide]

Bullets not appearing to spawn at muzzle, even though I spawn them there

what could be the reason?

[dire fjord]

@solemn siren I didn't make the plugin, but I'm thinking of things like DON's AI pathfinding plugin, I believe it installs as an engine plugin and not directly into the project folder

Plus we have a company account that bought a license for Allright Rig, but not everyone runs the engine on the company account (we're all working remotely) that also installs as an engine plugin, so I think it needs to be moved to the project and transferred as part of the repo.

[solemn siren]

You can give it a try if it doesn't hurt, haven't tried that

[dire fjord]

I know it's not here in the test project i made to test those two plugins, despite being enabled there is no plugin folder, so I'm pretty sure they're just in the engine. I'll do a little googling on how to properly move those.

[solemn siren]

@sudden oriole I don't think anybody can give motivation. As a college student, I prefer taking up projects under profs so that keeps me going. Might help in your case 😉

[balmy tide]

can anyone please look into my problem if they have time? 🙂

[sudden oriole]

@solemn siren I only use Udemy to teach me

The courses are really good though, very informative

[solemn siren]

@balmy tide try reducing the size of the bullets maybe? It's really hard to point the problem without looking at your BPs, if you're using BP. You can try adjusting some values randomly to find where the issue originates.

[balmy tide]

I think frame rate maybe the problem

the bullet travels ahead before frame loads?

I printed out spawn point location and muzzle location, both were same

[celest vapor]

If I use a soft object reference and load it using this node, is there a way to unload the class?

[solemn siren]

Frame rate doesn't seem to be the issue, everything else looks fine. Did you try reducing bullet size? Collision might be in play.

@sudden oriole well if you enjoy it then try completing the courses I guess. That should be motivation enough. After having ample knowledge, you can work on your game idea and look up on youtube for specific problems.

[sudden oriole]

@solemn siren Yeah guess you are right. I guess it is just hard to get started game dev. I had the same problem when I first started 3D modelling. I HATED it but now it is one of my favourite activities

[solemn siren]

Lol I'm facing similar problems with 3D modelling. It's always hard learning something new for me.

[sudden oriole]

Yeah, guess that is the same with anything new you are looking at getting in to. I use Blender and I am still learning new things to this day.

That is my own fault though, I never look into modifiers and sculpting until far later into my time with Blender. I just kept to subdivision surface modifier and poly modelling

[brazen crow]

hey sorry to interrupt but i have a very simple question, will the circled multiplication node receive a different number compared to the circled Y pin, or will it give both of them the same number? in other words, is the random float node getting used twice, one per output, or just once, and giving them both the same number?

[radiant jasper]

can someone tell me how to update unreal engine

[sudden oriole]

think you gotta just download the new version, idk if updating from one to another even works

[radiant jasper]

source

https://docs.unrealengine.com/en-US/GettingStarted/DownloadingUnrealEngine/UpdatingSourceCode/index.html

[brazen crow]

what source

oh

[radiant jasper]

im trying to follow this

but it doenst make sense

[sudden oriole]

basically it is telling you to go to the Unreal Engine versions tab and then download the new version

you can't update it, you gotta download an entirely new version

[radiant jasper]

there's no way to update it?

then that tutorial wouldnt exist

why does it say to make a pull request or whatever

and what do I choose as the base and the head

[sudden oriole]

pull request? what are you even looking at?

[brazen crow]

github

stuff

[radiant jasper]

it says create pull request

but idk what to choose as the base and the head

[sudden oriole]

oh? I have never used github for Unreal Engine

[grim ore]

@brazen crow a pure node, a node without an execute wire (the white one) is ran every time is is needed (eevery wire connecting to it). In this case your pure node returns a random value every time it is called so yes it will be 2 different numbers (1 for each outgoing green wire)

[brazen crow]

damnnnnnn

how do i make it one value xD

[grim ore]

get random -> store in variable -> use variable

[brazen crow]

aw

was hoping to not do that

rip

[radiant jasper]

wait so how do i update

what do i set as the base and the head

the tutorial doesnt really explain that part

[brazen crow]

lol

[grim ore]

you are using a source (github) version of the engine and wnt to update it?

[radiant jasper]

correct

[grim ore]

how did you get it in the first place

[radiant jasper]

just cloned it

[brazen crow]

oml mathewW knows everything 🥺

[grim ore]

which branch did you clone?

[radiant jasper]

just the entire unrealengine

[grim ore]

yeah thats not how it works tho, I would assume Master or Release then. hell it could be promoted

[radiant jasper]

uh how do I check

[brazen crow]

MATHEW UR THE ONE WITH THE "WTF IS" VIDEOS

[grim ore]

well how did you clone it?

[brazen crow]

NO WAY

[radiant jasper]

i just cloned the whole thing

[grim ore]

so you went to the command prompt and typed "clone unreal engine" ?

[radiant jasper]

noo

on github.com

[grim ore]

or... did you use github desktop, or sourcetree or fork or

basically you would go to your program you used to clone and open up that tab for the repository. It would probably show a bunch of lines with the commit messages and dates.

[radiant jasper]

i just downloaded a zip file

from github

OH FOUND IT

release

[grim ore]

ah ok so then yeah that is not cloning, that is just downloading a .zip

[brazen crow]

xD

[radiant jasper]

cuz the name of the folder is release

[grim ore]

in that case you have no actual repo software installed so your best bet is to just do the same

download the latest release zip, unzip it over your old release, open up VS and clean the project then rebuild it

[radiant jasper]

that wont fuck anything up?

[grim ore]

depending on the last time you download it, you might not need to update

[radiant jasper]

my version is 4.25.1

[grim ore]

if its the release branch, it should not. If it's an actual engine version tag then 99% it should not. if it's master, hope you have fire insurance

yes release is currently "UnrealBot Merging final 4.25.3 release
df84cb4
yesterday
Git stats
171,084 commits"

so if you download the latest release, overwrite your existing source, and rebuild it you should be fine

[radiant jasper]

i edited the source code slightly to fix a bug with packaging for iOS

will that effect anything

[grim ore]

then you will lose that change

[radiant jasper]

pretty sure they fixed it in 4.25.2 tho

or atleast thats what some worker at Epic told me

[grim ore]

you could go into that file, make a copy of it somewhere, then overwrite all the older stuff with the new

then you can go in and check to see if that fix is in the new file you just updated, and if not you have your old code to put back into place

[radiant jasper]

is there any real reason to update then

[grim ore]

only if you need something that was fixed or updated in the new code

thats kinda the only reason to update ever lol

[radiant jasper]

i mean xcode 12 support sounds nice but prob not worth the hassle and risk of fucking everything up lol

[grim ore]

yep yep

technically you could download 4.25.3 into a new folder and compile it there and see what happens. at the worst if it breaks stuff you can just go back to the older version of the project

[radiant jasper]

and does updating fuck up projects

[grim ore]

major versions, yes. minor versions, it should be fine

again at the worst, make a copy and open the copy

[radiant jasper]

Ok, so like when 4.26 comes out i wont be able to update my current projects?

[grim ore]

sorry. what i meant was you cant go back if you have a problem.

[quick plover]

How do I possess an imported third person char? I'm working on a blank level and can't make to control the character lol

[grim ore]

@quick plover click on it, find the auto possess section in the details panel, and set it to player 0

[radiant jasper]

wait mathew whats ur yt

[grim ore]

updating a project from .25 to .26 should be no problem unless something major happens you just cant go from .26 to .25 if you run into issues (again what backups/source control is for)

[quick plover]

oh man thank you, i was doing some blueprints things lol

[grim ore]

https://www.youtube.com/MathewWadsteinTutorials @radiant jasper

[quick plover]

now, is there a way to make the character invisible to the camera?

I parented the camera so it looks like first person, but i dont want the arms to show up

[grim ore]

in the mesh details there is an owner no see checkbox

[quick plover]

thanks!

[balmy tide]

Frame rate doesn't seem to be the issue, everything else looks fine. Did you try reducing bullet size? Collision might be in play.
@solemn siren I have turned off the collision, still the same

I adjusted the location of the players arms and hit play again then this started happening

[grim ore]

since it's a C++ project run it in visual studio and when it crashes it will show you where

but its pointing to the UseAmmo function and a line with the error

[rough knoll]

well my shit is still freezing. idk man

reinstalled ue on a main internal drive and no help

i probably just need more ram.

i dont get it though because people package shit on like 8gb of ram

[grim ore]

have you tried just cooking content without packaging

[open gorge]

how much of a hassle would it be to reinstall windows?

[tiny axle]

are there any intro vids for complete beginners?

[open gorge]

Several

[tiny axle]

which one is the best? most detailed or easiest to understand?

[open gorge]

that, i'm not sure about. I just dived in a figured things out as I went.

[rough knoll]

@grim ore wdym

@open gorge i bought a couple of 8 gig dimms. if those dont fix it then ill reinstall windows but im not resetting my pc for no reason

[open gorge]

fair enough

[rough knoll]

i'd also have to move my projects i assume

[open gorge]

a reinstall of windows would cause a need for that yes

but at least you have your external

[rough knoll]

its not on the external

well i could move it ig

[grim ore]

if the project is crashing on package you can try to just cook before packaging to see if it helps. It's in the file menu.

[rough knoll]

not rly the project its my entire pc because it gets to 99% mem usage

[grim ore]

@tiny axle read the pinned message in here for links to suggested tutorials.

[rough knoll]

u know what? fuck it

ill reinstall windows rn

[grim ore]

Try cooking first. If it fails out of memory reinstalling isn't going to help

[tiny axle]

ok ty

[rough knoll]

everythings worth a shot, imho

plus it wouldnt be too much harm as i dont rly have too many important files

and what are important i can put on the external

[plush yew]

@rough knoll did you check the logs? they might give you some insight into why the system stalls or has an issue. check Unreal Engine 4 Documentation > Engine Features > Directory Structure for the locations of the .log files

[rough knoll]

i know why it stalls lul

its because it hits 100% ram usage

it only struggles when it gets to the building textures part

which is where the ram usage gets to 100 and the comp dies

[exotic thicket]

if RAM hits 100% then it's probably gonna be swapping pretty hard so yeah that'll take a while

[rough knoll]

thats why im gettin more

so it will not hit 100% as easy

[north stream]

what's the best way to start a crowd-funded campaign for an Unreal Engine game ?

i would prefer to give backers a copy of the game, if possible

[exotic thicket]

Depends on your longer term plans after the crowdfunding I guess

For example, if you plan to release on Steam, you could probably give the backers codes to redeem it on Steam

[north stream]

what about epic launcher ?

my original question, is on which platform ? (Kickstarter, Fig or some alternative)

[distant totem]

@rough knoll you dont have incredibuild installed with visual studio do you?

[stuck linden]

So my character is walking fine to the left and backwards but when he's walking forwards it's weird it looks like something is blocking it

How to record a video in runtime

[dense hatch]

@idle hearth there's two plugins that I know of, one called FrameCapture and one called UEVideoRecorder

[worldly rose]

get random -> store in variable -> use variable
@grim ore @brazen crow Would Random → + 0 → <multiple output wires> work? To avoid extra variables. Is there a better "do nothing" node one can use?

[bronze vault]

Sorry if I missed it. But what is the color code in the looking-for-talent section?

[plush yew]

@bronze vault compensation type: unpaid, paid, royalty

[bronze vault]

@plush yew Ah. I see it now. Thank you very much.

[glacial pecan]

this feels weird...

[tender pecan]

careful with using a foreach and a remove by index. it can have unexpected results, where after a remove the indices shift. can use a reverse loop should work better.

[glacial pecan]

@tender pecan thanks! I used a set before and then remove items, but this time it's in a macro which means I can't use a local variable 😛

[tender pecan]

no need for any extra variables, simply iterate from length to 0. 🙂 although your remove will work, it may cause issues if you say keep references to these indices somewhere, otherwise it may not be an issue at all.

[glacial pecan]

I'm not, I'm just clearing out indexes that doesn't have a specific flag set (and always use for loops when dealing with that array)

(it's interesting that you can have local variables of most things in macros, but not sets, btw)

[glossy lynx]

I'm a Unity guy and I wanna port my old Unity project to Unreal Engine. What steps should I do to make the switch?

Prefer C++ btw

Didn't touch Unreal much

[serene birch]

scope of the question is too big, it depends a lot on what your old projet does

[glossy lynx]

Not sure starting tutorial/guides would be good idea

[serene birch]

try finding a UE4 tutorial for the same "genre" than your old project first I guess

[glossy lynx]

Old project was just simple Third Person Shooting

[glacial pecan]

@glossy lynx search for Unreal for Unity users... Epic has an official tutorial series on their website for you

but also prepare for some steep learning curves... I too came from Unity where you're free to do things the way you want, but in Unreal, it's Epic's way or the highway 🙂

[plush yew]

@glossy lynx UE has a third person shooter starter template as well and some stuff on the marketplace and you can probably begin by porting over the assets manually one by one over the base template with what you had in unity

[viral rivet]

can someone help me find the problem when i bake the light i get this weird GI? i have like 10 indirect bounces and 8 skylight bounces and it still looks like i got not even 1 bounce

[plush yew]

@viral rivet looks like the sun is hitting the roof, might need to make it one sided material or remove some of the faces, try moving the roof

[viral rivet]

i had it single sided before but then i had the problem that the wall on the other side (with the sun in the back) was completly lit and i read somewhere that single sided geo can sometimes cause some problems so i figured i would make everything with a thickness
shouldn't the lightmap be calculated differently on the inside ?

that was my problem with the single sided variant

normals seems fine, no overlapping uvs and the garage is modelled in one piece

[plush yew]

@viral rivet you may need to place the light origination points inside the structure, or have translucency on the top materials. if the goal is to have the light shining inside the windows then ensure they have the proper translucency. sorry for delay in replying.

[plush yew]

Hey guys, I have an issue.
Two of my submaps doesn't inherit lights from persistent level, and after rebuild they always appear dark. During build light it showed warning that two submaps (that are dark) share same build data GUID.

[kindred vapor]

guys any idea why would my music speed up itself in the build
in the editor it plays normally

[celest vapor]

@glacial pecan I noticed your for each loop remoing an index. when you remove an index it shifts the rest of them sometimes skipping an index. You should use a reverse for each loop

That should prevent it skipping and potentially removing the wrong indexes

[dark wagon]

A simple problem has me losing my mind: I can't seem to get my projectiles to ignore the pawn that fired it. I have the mesh component of the projectile (with the collision) ignoring the pawn, and the pawn's mesh component that has collision is ignoring the projectile actor. I am printing the display name of both. However in-game they still collide. What could be missing?

If I fire a projectile of the parent class here (straight projectile) it ignores correctly, but when I fire a projectile of a derived class (with no modifications) it collides.

normal console log

when I fire the derived class...

Why?

[jolly jungle]

If I do save game to slot with a custom save game class, will the save still be there if the game gets closed and reopened?

hello guys I have question, is there docs or page or something that I can check normal amount of tris about every mesh, like how many tris is normal for cars, windmill, tress, whatever

[whole quarry]

There is no normal amount @plush yew

It depends on your target hardware

[celest vapor]

is there a way to execute an event whenever a variable is changed without it being set to repnotify?

[plush yew]

for normal pc, not AAA

[whole quarry]

@merry gazelle if you just want to make a user interface, ue4 isnt the right tool for that

@plush yew define normal pc

Pentium 4 is a normal pc yet wouldnt run ue4 at all

[plush yew]

no no

I mean normal pc for running ue 4

like for i5 350 and gtx 1050ti

for this system

[whole quarry]

@glad pelican fbx from blender is reversed engineered and is not properly supported, only diffuse comes trough

[plush yew]

for 8gb ram

[whole quarry]

Can be 100k per mesh, tho using LODs is always a good idea

[plush yew]

I need to know cus my level has so many tris and I need my artist to optimize so many meshes cus the amount is so big

[whole quarry]

Optimizing to the max is also a good thing

[glad pelican]

@whole quarry how do i export as diffuse? sorry i never heard this term before

[whole quarry]

Diffuse color....

The most basic color used in the material

[plush yew]

yeah but idk how I can optimise, now I open every mesh and set the log group and hope to raise some fps-xD

[glad pelican]

i am not aware of which step in the export pipeline we're at remco

[whole quarry]

Its easier to remake the material in ue4 than in blender

[glad pelican]

ok

[plush yew]

Diffuse is basically the texture without any depth whatsoever

[high stump]

@plush yew there is actually a document that lists the tris counts of most asset types for current gen

[plush yew]

yeah

can you send it?

[high stump]

I'll see if I can dig it out

[plush yew]

Ok good

send it in dm please

[whole quarry]

Use LODs tho

@plush yew

[plush yew]

Id like to know that too @high stump

[glad pelican]

i'll redo all my materials i think. thank you 🙂 any suggestions for free materials websites? i got a month of substance and was using sbsars but that is limited to 30

[whole quarry]

No point in having mesh with 100k tris if only 4 pixels is visable from a large distance

[plush yew]

Obv

yeah I try but the problem is that the meshes are not our and I didn't do the level, the level designer did the level and now is problem that I can't create lods cus i need to reimport them but I can't cus I don't have them

Characters Id guess are around 25k tris for current gen

[whole quarry]

Thats why most devs make their own meshes

[plush yew]

Can be less if normals do most the work

Which they can

[high stump]

https://polycount.com/discussion/141061/polycounts-in-next-gen-games-thread
This is a little messy, I've seen a spreadsheet that took this info and made it really tidy

[plush yew]

yeah but I can't make every mesh, the idea of the packages is to help you to get the meshes and put them in the level not to go to optimize them

[whole quarry]

Be aware that next gen is aimed at the most latest hardware

Might run shit on the avarahe computer

See the steam hardware survey to find the current avarage hardware config

[plush yew]

this is for games not for meshes like tree or windmill or whatever @high stump

[whole quarry]

A polygon is a face of a mesh

[plush yew]

man, I don't have money to buy latest software, also the games are made for as many as possible players with normal pc-s not for latest gpu and cpu....

[high stump]

This is the spreadsheet for anyone that's interested. It's a little dated, but still a useful reference
https://docs.google.com/spreadsheets/d/1xJmSuBZbdMOlIcdXmO9hu46GJ7-wIiWCclJwimIOJa4/edit#gid=0

[plush yew]

Boly moly, some games are fine at around 20k per character, then you got ones with 150k tris per char lol

Every heard of normal map, jeesh

[whole quarry]

Normal maps cant make curves

[high stump]

depends on the genre, how close you get to things etc

[whole quarry]

So if you dont want blocky outlining, youre bound with higher vertices

[plush yew]

survival open world

I want to optimize this fucking level 😦

True Remco

[whole quarry]

If you want to optimize: make your own meshes and make LODs

[plush yew]

One thing's curves the other thing is detail up front

Does unreal have built in lod?

[whole quarry]

Yes

[plush yew]

Cool

[whole quarry]

It can generate LODs for you

[plush yew]

Thats cool

[whole quarry]

The but in there is: its automated so you dont have much control

[high stump]

@plush yew polycount isn't the only thing to influence framerates: draw calls are your number one enemy

[whole quarry]

But also: even dark souls 3 uses automated LODs

[celest vapor]

I have a quick question, you said i can generate LODs for you, when it does that does it just generate them from one model you imported or does it create its own genreation asstet persay

it*

[grim ore]

@plush yew you can have UE4 auto generate LOD's from meshes in the engine.

[high stump]

also LODs can sometimes be a bad idea, because they add to draw calls

[plush yew]

Yes draw calls

where is this option?

[whole quarry]

@plush yew how long have you been using ue4?

[plush yew]

2018

but not everyday

Merge all foliage into a single object

when i have time, motivation and yeah

[whole quarry]

Once a month?

[plush yew]

Like grass and shit

differently

[whole quarry]

If you have such an time window to dev, i dont think a survival game is in your scope

[grim ore]

https://docs.unrealengine.com/en-US/Engine/Content/Types/StaticMeshes/HowTo/AutomaticLODGeneration/index.html

[whole quarry]

Those kind of projects have usualy a team of people working on it dedicated for years

[plush yew]

Is merging all grass into one object a feasible idea for performance?

[whole quarry]

No

[plush yew]

Strange

[whole quarry]

It will dramaticly increase loading times

[plush yew]

Thats how we did it in the ol modding days for morrowind

How do you handle foliage then?

In a performant fashion

[high stump]

instances

[whole quarry]

By using the foliage painter or from a material

[plush yew]

I mean

[whole quarry]

Which adds them into ISM chunks

[plush yew]

So foliage painter?

Is the best way?

[whole quarry]

That gives you the most control

[plush yew]

Okay

Thanks

[whole quarry]

Np

[plush yew]

Am currently learning how to use cpp with unreal and oh boy

Not a cakewalk

Even assigning meshes to stuff is... Challenging

[whole quarry]

Aye, C++ has already a learnung curve, ue4 cpp even bigger

[plush yew]

I didnt find learning c++ hard since my base was Pascal

But the amount of shit to memorise in unreal is obsene

But I guess I gotta invest some hard time into it

I have so big interest and inspiration in survival games that's why I work on this

You gotta have enough time

is there a docs or something for learning cpp for ue 4 cus I use bp now but I have so big interest to work with cpp?

You gotta learn cpp first

I am learning and working with bp for 2 years

Then I found a lot of stuff online but its seems like a hell of a curve

[whole quarry]

If you have to learn cpp prior your project to avoid bp, expect a delay of at least a year

If time is sparse even longer

[plush yew]

Not sure if a year is what you need? But I guess the more practice the better yeah

and some people told me that from bp to cpp is easier than directly in cpp

[whole quarry]

Depends on your programming knowledge in general

[plush yew]

Probably because you know the names of nodes and stuff

I worked with cpp, c# and python 2017 but stopped cus it was boring for me

then I started unreal engine

thats it

[sick estuary]

Morning. I'm probably going to get flak for this but I couldn't find an answer online after looking... Are things created in UE4, work in UE3 as well? Probably not but asking anyway.

[plush yew]

xD

It is boring

[whole quarry]

@sick estuary no

[sick estuary]

Thought so. Thanks

[neat forge]

Does anyone have any optimization tips for things like particle effects for fire? I have a lot of fire particles

[vestal ferry]

hey, for some reason, i have a cliff in my scene, and when i get close enough to the border the simulation just stops and i can't control my character anymore...

https://youtu.be/NDhykqiuzKs

to illustrate my problem

[solemn siren]

@neat forge yeah, the lesser you use particles, the better it is. You can try searching for workarounds. E.g. using a flipbook animation of fire on a plane which rotates depending upon where the user is. And so on

[neat forge]

Thats a good idea

[plush yew]

Animated sprite

[neat forge]

Im making fire propagation, I have done almost as much as I acn for optimization in blueprints but Id like to make the particle better too

Thanks I will look into those

[shadow jewel]

I need help with my project

I can't make a chat box for users to use

I am using Unreal Engine 4.24.3

I think

[solemn siren]

@vestal ferry did you add any logic for what should happen when your player goes near the cliff?

[shadow jewel]

Does anyone know who could help me with my game?

[vestal ferry]

@solemn siren no, it's just a landscape with a height map and sculpted

[solemn siren]

@shadow jewel you can look up in the net if you want to make a chat box from the beginning. Otherwise, you need to be specific about your problem.

[shadow jewel]

@shadow jewel you can look up in the net if you want to make a chat box from the beginning. Otherwise, you need to be specific about your problem.
@solemn siren I have

And I can't do it

I follow what they do as well

I have a page where people can enter a Username, and then When I want to try to pass the variable through, I am unable to

"When I want to try to pass a variable through I can't", through different files I meant

[solemn siren]

@solemn siren no, it's just a landscape with a height map and sculpted
@vestal ferry when you say you're stuck, do you mean you lose all controls or the character seems to get stuck but other inputs work? You can try to add logic to print something during a particular key press.

[shadow jewel]

I am so confused

The chat still doesnt work

is there a "help" channel?

[solemn siren]

@shadow jewel try asking it in the multiplayer channel with more specifics. People there might be able to help

[shadow jewel]

ok

[solemn siren]

I'm not sure though

[vestal ferry]

@solemn siren i lose all control of the character. the game still runs, but i have no controls as if it was removed from the scene. i had an earlier version of the project with a 1st person gun, and it would disappear

[misty creek]

Sounds like it's getting deleted

But I don't know exactly how

[solemn siren]

can you check the output log?

Something must be there

[misty creek]

Check your z kill height

[solemn siren]

Moreover, how big is your map? There might be issues if you walk too far away from spawn point

[rocky radish]

check the z kill height as Tate said

[vestal ferry]

yeah will check the Z Kill height, my map is'nt that big

yeah that was that ! thanks !

[plush yew]

Uhh I need to edit multiple static mesh values but I cannot find the property matrix 🤔 Any help?

[jolly jungle]

Someone shud try to make a 2d game with the widget system

[grim ore]

@plush yew it is under asset actions

[plush yew]

Ah I didn't see that, Thank you very much!

[normal plover]

I know this seems like a very stupid question, but is it possible to export a build from minecraft using the 3D export option in a structure block, over to Unreal Engine?

[exotic thicket]

It probably depends on what format it exports in

[untold swallow]

Hey Which website shall I use for my mobile game ads? Is admob good ?

[opaque crystal]

@normal plover you could get it in as a mesh/model, but it won't have block functionality as I'm assuming you're aware

[civic dust]

Hello I need help. Yesterday I was doing game in Unreal Engine 4 and after that I saved it. Today I tried to complete my project but UE 4 was lagging ( about 1 frame per 15 seconds ) After that I turn off UE 4 and I started playing Grand Theft Auto 5. Surprisingly game was working smooth. After 2 hours I wanted to play Fortnite but game is lagging like Unreal Engine 4 ( about 1 frame per 15 seconds ) Other programs are going without any lags only Fortnite and UE 4 aren't going smooth. Someone know what can I do?

[normal plover]

@normal plover you could get it in as a mesh/model, but it won't have block functionality as I'm assuming you're aware
@opaque crystal do I export it as a .obj file to do that?

[opaque crystal]

If you can export it as an obj it should be easy for unreal to load it in as a 3d model, yes

[normal plover]

Ok cool, ty

[opaque crystal]

.obj is a file format loved by a lot of things. Could also export it to a 3d editor like blender

[vocal beacon]

I just downloaded the megascan plugin and now I can't compile. I get these errors but I'm still kind of confused as to how to fix them

[vocal beacon]

@plush yew The launcher is so broken it won't update

[rocky radish]

@onyx hazel dont send this on multiple channels

[vocal beacon]

Huh

[plush yew]

odd problem here guys, my textures/materials are showing up torn and smeared/joined at angles, no clue what is causing this but it seems to take place with every texture

@civic dust might be your system or ram spec - check Unreal Engine 4 Documentation > Get Started with UE4 > Hardware and Software Specifications and make sure your computer meets that spec. then consider opening task manager and getting rid of any processes that take up a lot of CPU or RAM utilization.

[grim ore]

@plush yew open up the texture in UE4 and look at it's compression and texture type

those are probably causing the issues. Also if it's not power of 2 it might cause issues with the mip maps

[plush yew]

i assumed that was the issue too

tweaked a few settings but the problem persisted

[somber quail]

Looks like padding due to alpha. Make sure to apply your alpha to opacity and check results then

and/or change tiling method to clamp

[plush yew]

alright sec

👍

it was the clamp yeah

see i dont even remember touching those settings or if that was the default to

bizarre

[somber quail]

default is wrap

[plush yew]

works quite simply, thanks!

strange though the texture is still appearing warped

[somber quail]

in what sense?

[plush yew]

just the texture sample preview

the L in control is still getting padded

[somber quail]

It'll do that with thumbnails

as long as it looks good in viewport does it matter? 😉

[pale token]

Which is the best channel to ask for help in?

[plush yew]

yeah it doesnt matter i guess, just weird compression

[somber quail]

Whichever one is most applicable to your situation

[plush yew]

just had to make sure it worked for other material blends modes, which it does seem to

[pale token]

Uuuhh.. I guess visual fx if its for lighting? 😂

[somber quail]

I guess #graphics or #aec-visualization

[gentle crypt]

where are the landscape and vertex painting modes gone?

[fluid swift]

If I assign anything a translucent material I cannot select it :/

Any tips on this?

There's a box infront of that one

[plush yew]

@gentle crypt To the right on the tool bar you should see a paint icon you can click that

[fluid swift]

Fix is pressing "T"

[restive zinc]

does anyone how to make one ai alert others that there is a player thats been spotted i want to do do this in the blueprint not in a behavior tree I've tried it before but its just a pain in the ass I'm more familiar with blueprint
ive tried asking this in ai but no one is active in that channel

[quartz grotto]

Hello everyone

[lost reef]

@restive zinc have that ai trigger an event in the rest of them

[restive zinc]

so a custom event

[lost reef]

@restive zinc that would be one way to do it, other ways as well, so just a suggestion

[restive zinc]

@lost reef how can i have one event activate for all the ai

@lost reef custom event >>>will get all actors of class>>>ai move to

[lost reef]

A simple way would be to get all actors of class and when its triggered for ai "x" it gets the rest of the ai and triggers their custom event

Or you could have them listening for when its triggered in eaxhother

Like i said, numerous avenues for you to explore that idea, good luck!

[restive zinc]

@\

[plush yew]

if one AI triggers multiple others in a chain reaction, can't there be a mass AI trigger for only a small localized event (if an ai is 1,000,000 Meters away from the player, as long as there is a chain to the ai it will still trigger)? it's easier to just use perception / EQS / line trace to get the AI to "detect" players and maybe a bit more traditional.

if you do it that way though by event triggering, then maybe you should limit the radius distance from the player @restive zinc

[restive zinc]

@plush yew get all actors of class is not working what im trying to do is that when an ai sees an player with pawn sensing call event get all actors of class and ai move to is not working?

[plush yew]

maybe add a tag to the player and get all actors with tag instead? i usually don't use get all actors though. just trigger it manually via an interface.

[restive zinc]

how do i add a tag to player? @plush yew

[plush yew]

select the player and add a tag in the details. Unreal Engine 4 Documentation > Gameplay Guide > Gameplay Tags

[vocal beacon]

I got a problem where one action mapping doesn't respond at all, no matter what key I choose or if i delete it and re-add. Everything else works fine. Why?

[restive zinc]

@plush yew add a tag to player right

@plush yew ok done

[plush yew]

@restive zinc can you maybe work on the issue for a little while like an hour or two and get back to me or someone else in #gameplay-ai for more info on it please?

[restive zinc]

ok

[civic dust]

@civic dust might be your system or ram spec - check Unreal Engine 4 Documentation > Get Started with UE4 > Hardware and Software Specifications and make sure your computer meets that spec. then consider opening task manager and getting rid of any processes that take up a lot of CPU or RAM utilization.
@plush yew Yesterday everything was going smooth. But today it is lagging idk why. My computer meets UE4 specification ofcourse. (Fortnite is lagging too but other games are going on 60 FPS)

[plush yew]

@civic dust UE Is highly optimized. I would only suggest doing the following:

1. try restarting.
2. try updating your graphics drivers using nvidia geforce experience or the latest AMD drivers.
3. make sure to run the latest version of windows update
4. make sure no other apps are live while you run unreal or other games.

i usually experience almost zero CPU lag any time I'm doing my work, but then again I have high RAM. try checking your ram utilization in task manager i attached a picture of my current ram utilization (my CPU utilization hovers around 10% most of the time too). To use task manager effectively: go to windows start -> run -> taskmgr and then look in Task Manager -> Details. Sort by CPU. any high CPU utilization apps that are not marked as SYSTEM can be safely killed usually.

[solemn orbit]

hello

i have a weird animation error

i downloaded animations from mixamo

and in unreal engine 4 for example the walk or run animation they like walk forward, so when i play my game with these animations, the character gets moved back

[plush yew]

did you check Unreal Engine 4 Documentation > Engine Features > Skeletal Mesh Animation System > Using Mixamo Content?

[solemn orbit]

no where can i find this

[plush yew]

the string i pasted above is from the unreal documentation.. so

you would google the string and it shows up in results.

i don't typically paste links here in UE slackers 🙂

[solemn orbit]

okay i am right now reading the documentation but still dont know how to fix it

[plush yew]

@solemn orbit from what i remember about this, the character has to be rigged / scaled to the epic skeleton to make it snap in by default. can you please consider asking in #animation ? i can try to help there a bit later if it's okay.

[solemn orbit]

okay

🤦

i just found an option in mixamo

i have to tick it

[plush yew]

ah fixed it?

[plush yew]

there you go. i remember in place being an option i had to use before in my animation work

if you don't use that it can wander off the origin, right?

[solemn orbit]

yes it walks forward

[plush yew]

cool. i had this issue before too.

[solemn orbit]

but you cant set that option for an pack

[thorn lichen]

Any game artists have an idea how to achieve these kind of effects?
I was thinking of a texture on a flat plane mesh but not sure how to get stylized smoke

[solemn orbit]

for smoke, you could use a cube or a sphere/cylinder

[plush yew]

a flipbook plane with the correct opacity settings for transparency would be the way to go for planes with animated textures i believe.

maybe a warped mesh that animates over time with keyframes (could accomplish this by either manually warping the vertices of the mesh in blender or a similar tool, or applying mesh displacement to a 3d object like a sphere or plane and changing the displacement value over time to be higher in the Z value)? if that doesn't work try #niagara or #visual-fx cascade particles of puffy smoke billowing upwards and scaling down as they go higher.

[jolly jungle]

Do I have to do any legal stuff to put the powered by unreal thing in my game even if its going for free on itch.io? I don’t have a game yet but I’m just curious

[plush yew]

@jolly jungle not needed. only thing that is needed is the royalty payment as necessary https://www.unrealengine.com/en-US/faq

[jolly jungle]

Ok

Wait is ther a royalty for using the logo?

[plush yew]

@jolly jungle no, if you add the logo as a splash screen you're helping epic by mentioning their tools were used in making your game.

[jolly jungle]

Ah

I’m on vacation for the next few days but after I’m gonna try to make a sidescrolling shoot em up game

I have tried to make first person games in the past, but I just overcomplicate them until it is something that i will never be able to do

[exotic thicket]

^ this is what I do

then I never work on it

lol

[plush yew]

@jolly jungle to start out it's a really good idea to use #fab products and get those into your game or even make an entire game template from them. i did that a few times and after i extended the base classes enough it worked well and most of my games are published on google play or steam.

i recommend template extension for sure. if at least to get inspiration and a good foot forward

[exotic thicket]

I'm always amazed by people who can just take assets and use them in their stuff... I get too annoyed by the fact they don't look the way I want them to or they don't fit with the other assets :D

maybe I'm just bad at choosing assets that match

[jolly jungle]

Ok, I’ll look into that, I have been screwing around in the engine for a long time and I understand how it works, but I have just never made anything bc I can’t motivate myself

[plush yew]

haha well the marketplace policy is luckily pretty fair. anything is fair game as long as it's in the ue marketplace umbrella

[jolly jungle]

I’m the kind of person who cranks out infinite ideas but then never does them

[plush yew]

@jolly jungle you should put your ideas in google docs or some text file and then sort by highest precedent. i have this issue too.

60+ pages of ideas, i sort by most important or interesting and accomplish one by one

[jolly jungle]

I’m also gonna use mega scans cuz I can’t do art

[plush yew]

that way productivity is still accomplished despite high volume of ideas

yeah the marketplace megascans are great. free too.

[jolly jungle]

I alredy have bridge and mixer installed too

[plush yew]

nice

[jolly jungle]

And I have a friend who’s good at blender so he can make models

Wer gonna try the real time collaboration thingy

How well does that work

[plush yew]

I really love blender for sure. i generally advocate FOSS software for creative. i actually recently purged all adobe / autodesk tools from my pipeline

[exotic thicket]

that's pretty tough because substance and photoshop are pretty great

[plush yew]

you can always do live streaming or discord calls / screen sharing to collab live.

[jolly jungle]

Yeah well adobes a jerk

[plush yew]

substance painter is great true

[hearty walrus]

how do I make a wall go semi-transparent if the camera is in the way>

[jolly jungle]

Quixel mixer is starting to become a more and more viable alternative to substance

[plush yew]

@hearty walrus line trace from the camera to the player, if the wall hits the line trace, set the opacity of the wall material in your material blueprints.

[hearty walrus]

...what?

[plush yew]

Unreal Engine 4 Documentation > Engine Features > Physics Simulation > Traces with Raycasts > Traces How to Guides > Using a Single Line Trace (Raycast) by Object

[vocal beacon]

So I never really got an answer to my issue so where can I find the project config file?

[plush yew]

they are in ProjectRoot/Config/DefaultEditor.ini etc.

are you talking about engine config or game project config?

[vocal beacon]

Just the project

Where I find the input settings

[hearty walrus]

@plush yew how efficient is this?

[plush yew]

check https://docs.unrealengine.com/en-US/Programming/Basics/ConfigurationFiles/index.html
DefaultInput.ini is for input @vocal beacon

[jolly jungle]

Can the player class be a pawn or does it have to be a character

[rough knoll]

?

why are my assets and ground so bright

my sky is the color i want it

[plush yew]

@hearty walrus if you do the line trace on a timer say once a half second it's way better than using tick.

if you want to "fade" the opacity then you might have to do it at a higher frequency

[vocal beacon]

Thanks

[hearty walrus]

there's only 4 walls, and the camera is clamped so you can't go too low

and it shouldn't fade, just snap to something like 0.3 opacity

[plush yew]

have the timer trigger once a half-second then, it's quite fine for blueprint tick time and they will still be able to always see the player at all times.

[rough knoll]

im gonna try rebuilding my lighting

and it hopefully doesnt break everything

[ember star]

Can someone advise on the right way to design this? I have an enum of professions. I want to associate a row of data with each enum, call it 'profession bonuses'. Where would I define and store this?

I have a struct to define the one row of bonuses. Should I create a class of 'Profession Bonuses' and define them all as defaults?

[hearty walrus]

@plush yew

here's what it's got so far - what's causing this bug, and how do I make it change the wall to be translucent? This blueprint is on the ThirdPersonCharacter template

[plush yew]

@hearty walrus use https://docs.unrealengine.com/en-US/BlueprintAPI/Utilities/Time/SetTimerbyFunctionName/index.html set timer by function name, make a custom event with the same name, and in that custom event you can set the opacity, etc.

have to go for a moment but i will be back later

[ember star]

@hearty walrus mouse over the 'error' for more details. probably need to set the event node

i think you uneed to 'create custom event' then wire it to that

[exotic cave]

@rough knoll : Can be several things: Check the settings on your scene's directional light(s), your skylight, and then your materials.

If the entire scene is way too bright, your directional light or skylight are probably set too high.

[opal totem]

I'm drawing a blank on how to make a float only a factor of another number like say 50 and if the float is 35 it'll return as 50

[rough knoll]

i do not have a skylight

i only have a directional and skysphere

[exotic cave]

K, what's the setting for the intensity on your directional?

[rough knoll]

2.15

lux

[exotic cave]

That isn't high. Turn off your eye adaptation just as a hint as well.

[rough knoll]

wheres that

[exotic cave]

Google is your friend...but I'll go get the setting for you this time.

Show->Post Processing->Eye Adaptation

[rough knoll]

ok that fixes the overly bright problem but my tree leaves are still the same green

isnt the color supposed to change based on the sky

[exotic cave]

I mean, to a certain extent.

Your materials will change with your skysphere mostly according to how reflective they are, as best I am aware.

What are you trying to do? Have a low-light scene?

[rough knoll]

yeah, nighttime

the trees are the same color they would be in the day

same with the ground

[exotic cave]

The trees and the landscape material you didn't make? 😉

[rough knoll]

well yes but ive seen them change color before

[exotic cave]

How? When?

[rough knoll]

i pointed the directional light upwards and they changed color. same with when i moved it around and made shadows

some parts were darker and some lighter

[exotic cave]

Absolutely. That's how directional lights work.

[rough knoll]

so then why cant this directional light lower the brightness of assets

[exotic cave]

Because you don't understand what you're doing, friend.

You need to learn how materials work in UE, I'd say.

Everything in your scene has an associated material. If that material isn't set up to automatically adjust to lowlight conditions, then it won't automatically go dark when you turn the lights off.

I'm going to go out on a limb and guess that the assets you're using were made for daylight scenes, and possibly don't automatically adjust to low-light conditions very well.

I would suggest reading through this, at minimum: https://www.raywenderlich.com/504-unreal-engine-4-materials-tutorial

[exotic cave]

It's a great notion that all materials in Unreal Engine ought to automatically adjust to every possible lighting condition. 😄 That's also more or less completely impossible as things currently stand.

If you want materials that adjust well to different lighting conditions, then those materials generally have to be engineered to a high degree of technical proficiency.

So, your next steps will rather depend on whether or not this scene is permanently low-light or if it has an adjustable day-night cycle or etc.

[rough knoll]

i'd want it permanently low light

are there specific low light trees?

[thorn scarab]

nah

there's no permanent low light trees

[exotic cave]

If there's no dynamic lighting changes required, you'll have to find your leaf material and tweak it a bit.

It's not too hard, but you do need to learn about materials and how they work. (And every UE user needs to learn that, so try not to feel too burdened about it all.)

[plush yew]

i think my ue4 files are corrupt i cant build in ANY PROJECT anyone experienced that?

[thorn scarab]

but if you're lazy you can delete direct light, skylight, fog, then add direct light first, see if you're happy with the intensity. then skylight same action, then fog

[exotic cave]

He says he's only got a single directional light so far, I'm assuming he's gonna have to go darken his leaf material a bit by hand.

[plush yew]

@rough knoll check https://docs.unrealengine.com/en-US/Engine/Rendering/Materials/MaterialProperties/index.html you can set the lighting intensity there or in the individual lights you have in your scene. light intensity set too high might cause blowouts, including not building the lighting when you see lighting needs to be rebuilt

[rough knoll]

so i should rebuild the lighting first of all

[thorn scarab]

@exotic cave i see unless he did some manipulations in camera exp or post process

[plush yew]

@rough knoll i thought you rebuilt the lighting a while ago actually.. not sure why you didn't yet? do that now.

[rough knoll]

i've rebuilt it once already

whenever i move a light it makes me do it again

[plush yew]

are you seeing ?

[rough knoll]

not rn

[plush yew]

do not move the light.

when testing

[rough knoll]

because i was mid-lighting build when ue crashed

now the message is gone idk

[plush yew]

@rough knoll im going to msg u in #graphics about this okay?

[rough knoll]

kk

[hearty walrus]

ooh

[lofty wave]

Could someone please help me with a problem I have?
Whenever a level is opened through a BP Unreal Engine just crashes...
I didnt change anything in the BP for the last few weeks and it also happens with new BPs

[thorn scarab]

delete, re-download, re-install and see if it helps @lofty wave

[lofty wave]

My projects will remain right?

[plush yew]

@lofty wave https://answers.unrealengine.com/questions/26701/view.html (Where are UE4 crash log files stored?) check the crash log first. based on the log, you can act appropriately.

[lofty wave]

...

Well too late now....

Ok I can stop the uninstallation

[plush yew]

after a crash or project failure (such as packaging failure) the log is always the first go-to

[obtuse pendant]

quick question, how do yall save your raw assets, like PSDs, blender files, etc.?

right now I just have a seperate folder in my projects root folder

[lofty wave]

same

[hearty walrus]

How do I make rooms correctly?

Most of the time they end up having parts sticking out

thanks

[stuck linden]

i'm having a very weird problem that no one on the internet had it yet apparently my character can only walk forward/to the right normally crouched
https://streamable.com/yss6dd

[rough knoll]

how do i get better fps lmao

i have everything on all low

and yet i only get 58

[stuck linden]

i reached to experts and no one figured it out

[rough knoll]

yet i can get like 60fps on all high in assassins creed odyssey

on epic i get like 20fps if that

[vocal beacon]

I'm going to try again to ask about my problem. I now have two action bindings that never calls my functions, ever. One of the functions is purely made to print out some text but the console never displays anything. Why?

[rough knoll]

are there any settings in project settings>rendering that can improve performance with less quality drop

[exotic cave]

@thorn scarab : Is that a fractal blueprint?

I have a client who might be very interested in that tech. You open to connecting?

@rough knoll : System specs?

[rough knoll]

i7-4790k, rx 570, 12gb of ram

[stuck linden]

there's no way no one knows a solution to my problem 😦

[rough knoll]

its not great but i mean it should be running this better

[exotic cave]

Not if you have a bunch of overlap on your foliage that you don't know about. 😄

I believe it's Alt-8 that will show you the shader complexity of your scene?

You might want to try that, and show us the screenshot.

[exotic cave]

K, and with it off? What am I looking at with regard to that red there?

[rough knoll]

water

[exotic cave]

Ah, understandable then.

[stuck linden]

Is anyone here good at debuggin/collision problems? if there is can i PM?

[exotic cave]

Poly count?

[rough knoll]

how do i see that

[smoky crescent]

What about a #Rider channel?

[exotic cave]

Please can you at least take a basic UE class man, this is killing me

You go to the little arrow in the upper left of your viewport

Go to "Stat"

[rough knoll]

mhm

[exotic cave]

Then there are various options you can use to see the polycount

I recommend Advanced->RHI

Though there's an easier one I can't seem to recall offhand

[rough knoll]

i assume thats what you need to see

[exotic cave]

Mhmmmm

You have 17m active triangles

That's a boatload

I have an i9/2080 and even I wouldn't dare go above 10m

Whatever assets you're using, they're very high-poly and not high-performance.

[rough knoll]

oop hold on

i think i know my issue here

or the thing behind the problem

yep

its the absolute abundance of grass on my ground texture

[exotic cave]

Yes, grass that is not well behaved will absolutely choke you.

[exotic cave]

Yup

You def need some better behaved grass.

[smoky crescent]

You can use aggressive LODing with grass.

[exotic cave]

He doesn't even know how all these assets work yet though

[plush yew]

@rough knoll you can use instanced static meshes for grass. or LODs like ponkkis said to lower poly counts at high distance from view.
https://docs.unrealengine.com/en-US/Engine/Content/Types/StaticMeshes/HowTo/LODs/index.html
when you have a question about an item in unreal and someone types it here you can google the term, he said LOD you can google the term and find more info on it by typing Unreal LOD

[exotic cave]

What pack is this that you're using?

UE Marketplace free assets are kinda notorious for these beautiful scenes that are absolutely impractical for actual game levels at least in my opinion

[rough knoll]

nah its not the packs fault its my stupidity thats at fault here. the grass mesh had a density of 1000

when on my grass mat

[exotic cave]

Yes, maybe turn that down a notch 😄

Looks great I'm sure

But, won't actually work

[rough knoll]

turning it down to around 100 has good performance its very splotchy and ugly

[exotic cave]

For what it's worth, this is part of every UE project. I have a little MOBA side project level going right now that I've audited a ton of assets for that I have to throw out, because they're beautiful and high-maintenance

[exotic cave]

I would suggest going and finding yourself possibly some better behaved grass assets.

That grass is lush and lovely and clearly only meant for closeups 🙂

[rough knoll]

alright

[exotic cave]

Good grass is not easy, I've been through several revs on my upcoming Marketplace pack and will likely have to do more revs.

https://www.unrealengine.com/marketplace/en-US/product/dynamic-optimized-grass-library

Epic bought Project Nature awhile back, they have lovely grass though it is pretty high-performance and might not work any better for you

It is per-blade rendering so tri counts are high however the author has a technique that really vastly decreases the amount of complexity per tri (basically nearly eliminating transparent overdraw)

[rough knoll]

do you think that grass density could have been the reason behind my 100% memory usage while packaging?

[exotic cave]

Sure

[rough knoll]

resulting in my pc crashing

[exotic cave]

Grass meshes are like any other mesh in UE

They cast shadows, they affect lighting

[untold hollow]

hi everyone

finally trying some unreal engine, and I opened up the advanced vehicle project

[exotic cave]

When you have a scene that's probably several hundred million polys or higher in its entirety (remember, building lighting builds offscreen stuff too) then your computer will have teh terrors building

[untold hollow]

and when I press play it's constantly moving backward and turning

I tried unplugging all gamepads

any ideas?

[exotic cave]

@untold hollow : I mean, I was going to suggest unplugging all gamepads 😄

It sounds like it's picking up an input somewhere that it shouldn't be, certainly.

[untold hollow]

hmmm

thanks

no idea where though I only have one gamepad

[plush yew]

recalibrate gamepads

and ensure the axis inputs are set properly and not reversed in the blueprint code if you made any modifications to it

[untold hollow]

no changes

[autumn elbow]

For the OnDrop function, How do I specify which item is the target widget to drop on ??

[rough knoll]

oh yeah

[untold hollow]

just opened up the vehicle starter thing

[rough knoll]

minor issue that i had when duplicating projects

i assume my look stuff got messed up

it removed my input bindings so i assume thats the problem

and i cannot look around

nor walk

[exotic cave]

That could certainly be it

[untold hollow]

aha!

I just closed unreal and restarted with the gamepad already unplugged

that fixed it

thanks guys!

time to dive in

[exotic cave]

Yes, you can't just unplug it when the system is active

It grabs a lotta stuff at startup in my experience

[untold hollow]

ah. ok. that makes sense

thanks again

this is gonna be fun

[exotic cave]

Now you all have to help me painstakingly reorganize my Marketplace pack to remove every single duplicated mesh I have 😄

It's only fair

sobs

[untold hollow]

k

[exotic cave]

I kid

[untold hollow]

ask me again later

[exotic cave]

This is my cross to bear

[untold hollow]

i guess I have one more thingy

my gamepad isn't messed up or anything

when I open gamepad settings in windows

everything is fine

[rough knoll]

how is 1.9-2m triangles

[exotic cave]

Acceptable

[untold hollow]

i just tried replugging it back in after starting and same thing

[exotic cave]

1-5m should be fine for most systems. It will always depend on the tris though.

[untold hollow]

is there a way to recalibrate within unreal?

[exotic cave]

@untold hollow : "Fine" is unfortunately very relative when it comes to most gamepads

[untold hollow]

right

[exotic cave]

1-5m tris is usually okay, 5-10m is getting towards the higher end of acceptable @rough knoll - however, it depends on the triangles so you can never just go by numbers alone

[rough knoll]

i assume it will get over 5m by the time i finish my environment

[exotic cave]

I had some 3k tri trees that literally were 20-30fps slower than the current 15k-30k trees, because I was modeling the trees per-branch instead of per-leaf, and it turns out that having large transparent areas in your triangles will choke your system like Darth Vader

[rough knoll]

all i'm doing is optimizing stuff for a debug build

its a pretty small area rn

[exotic cave]

You won't really have to deal with this stuff unless you start making your own assets 😄

Just be aware that giant triangles with transparency can be super pokey even if you only have a few of them.

[rough knoll]

ill try to get some low-poly grass

[exotic cave]

Ehhhhh shoot for "well-behaved"

The pack I gave you a link to is the most optimized Project Nature grass asset

You might try that

[untold hollow]

oh weird, something really strange is happening, if I press left, it's stops moving. If i press forward it stops turning

[rough knoll]

yeah i tried using one of the grasses there

[untold hollow]

it's like the gamepad is mapped all weird

[rough knoll]

i downloaded it and added

[exotic cave]

Still slow?

[rough knoll]

with 100 density (out of 1000) its 9m polys

[exotic cave]

I mean, how's FPS though?

[rough knoll]

30ish on epic

[exotic cave]

Yeah, not great

[rough knoll]

it went to 40 i guess

[exotic cave]

Yeah I know 😄

I have an i9/2080 and I consider anything under 60fps on my system to be the kiss of death

Because I know that's 15-30 on someone else's potato

Keep looking around, I suppose. Epic loves to put out these lovely screenshots of the grass system but real, actual, workable grass for levels be hard

Lots of the stuff they use for screenies just will smoosh actual lower-end gamer PC's

[untold hollow]

i just tried a different controller and same thing

wtf

[rough knoll]

with one of another there is 20mil polys with really low density at like 20

fps

[exotic cave]

Yeah

[rough knoll]

however it was animated

[exotic cave]

I wish my pack were released so I could point you in the direction of my grass 😄

However, Epic no likey the way I duplicated a bunch of my static meshes rather than properly swapping materials, so no luck on that

[rough knoll]

rip, this low poly grass i found was literally just rectangles and idk if i did something wrong or what but it looked terrible

[exotic cave]

No, most low poly grass looks absolutely awful 😄

Hey I know! Use Megascans grass!

It's free and you'll easily get FIVE fps with that grass

[rough knoll]

lmfao

[exotic cave]

But that FPS

Ship it

👌🏼

[rough knoll]

in the screenshot

it looks like that

it does NOT look like that on my project

very confused

[exotic cave]

Mhmmm, something clearly misconfigured

https://www.unrealengine.com/marketplace/en-US/product/meadow-environment-set

Go get this while it's free, last day free 😄

Could work!

[rough knoll]

i do have that actually

thats where i got my trees from i think

[exotic cave]

Try the grass from that

Or did you already?

And that's what was choking?

Here's my grass

[plush yew]

Is github a good way to backup saves on UE4?

[exotic cave]

You can't have it because Epic no likey my project organization yet 😄

[dim kelp]

cat walked on my keyboard and now my editor looks like this:

[rough knoll]

no i had a different grass

[dim kelp]

what setting do i need to undo?

[rough knoll]

fov

i think

[exotic cave]

Your field of view

Yeah

[rough knoll]

90

[somber quail]

just press z or x

[dim kelp]

z/x didn't do anything

[exotic cave]

Should be on your camera

[somber quail]

hmm that's the shortcut for fov adjust

[exotic cave]

Yup, might be something else in that case, possibly the viewport itself has a FOV override

It's probably on your viewport: https://docs.unrealengine.com/en-US/Engine/UI/LevelEditor/Viewports/ViewportOptions/index.html

[rough knoll]

heres the low poly gras i downloaded

[rough knoll]

is that fake transparency lmao

because its behaving like its a full rectangle

[exotic cave]

I mean, it is a rectangle

[dim kelp]

oh that's weird

[exotic cave]

All you'll get are rows of that

[dim kelp]

when i set it back to 90, it zooms back to 170

[exotic cave]

Will look fine when dead on, terrible from any other angle 😄

[rough knoll]

but like

why does it render as rectangles and not the grass thats shown there

should it not be transparent

[exotic cave]

@dim kelp : Cat magic 🐱 ✨

It should indeed at least render the transparency, sounds like a materials problem

[rough knoll]

is there a setting when importing an fbx that changes transparency?

[exotic cave]

Nope, that's your material

I mean, if all you're doing is importing the FBX and then using the default material that's created...

Then yeah, you're likely to have bugs

[dim kelp]

it resets the fov to 170 gradually, like zooming, even with keyboard unplugged

[rough knoll]

yeah thats what i did lmao
