Guys I got a simple question, does a core i5 2.5 ghz 8 gb ram laptop without GPU can be used to learn unreal engine ?
bitter iris
Question,
What does everyone use for Dedicated MP Servers with UE4? I'm in need of a new sys
I bought uWorks last year, came back to it here an there but todays files on the plugin are all broken. Owner has abandoned it.
sacred sun
anything that meets the min specs can be used to learn unreal. with those specs you'll have to have a fair bit of patience when working with materials, building lighting, packaging.
bitter iris
hundreds of people asking for support nothing :/
whole quarry
Not really a engine specific question but still related, but he also speaks about a different topic 😁
hexed dock
Can anyone recommend any library to do something more advanced for custom UMG painting beyond just box/lines/lines/text? Like circles, just for example?
plush yew
Can I upgrade a project from 4.23 to 4.24 by just opening it in the new engine?
next badger
@plush yew there's no way back, you may stuck on preview for months
plush yew
I need that chaos destruction and it wasn't working in my source build ):
fierce tulip
@bitter iris might want to contact mp team if he abandons it, since its still for sale.
bitter iris
@fierce tulip contacted for a refund as i paid £150 :/
next badger
some people claim that chaos won't be live for a year or so
cloud cobalt
It's unfortunately a common problem on the marketplace
@plush yew Beware that Chaos isn't ready for production yet
light thunder
Is there a YouTube or live stream or other resource that outlines how to take an existing rig model and converted to the unreal mannequin so as to use all of the animations that are currently available for the unreal mannequin? I'd ask #animation (i did actually) but there have been multiple other questions that haven't be responded to in 24 hours and this might be more of a basic question in any case
cloud cobalt
Export the skeleton, import it on Maya etc, re-rig the model
fierce tulip
@light thunder look for "ue4 skeleton retargeting tutorial" or so
plush yew
I don't understand why the Chaos Demo was working when I tried it in the non-source 4.23, but it (the feature itself) isn't working everywhere else or in other people's projects
light thunder
@fierce tulip thanks, I wasn't sure if it was just retargeting specifically but yeah, that's what I was looking for, thank you
cedar snow
OOC does uWorks come pre-compiled that users can't upgrade it to 4.23?
next badger
chaos demo is c++ project, it'a a monolithic build that will compile whole engine
cloud cobalt
Lots of people don't know how to compile stuff, and it's not like an abandoned plugin will compile anyway
safe rose
Doesn't matter how long it takes
It just needs to release whenever it does...100% stable and performant
Maybe when they do another "Stability-release" ... they've only done it once IIRC (4.10?)
Long overdue
Aye
We need more of these
Just one in the "20-series"
cedar snow
yeah, not defending abandoned plugins, but unless it's pre-compiled it should be straight-forward to upgrade
if all else fails move it to your projects plugin dir and fix it
cloud cobalt
laughs in 4.24 header changes
cedar snow
cries in installed but not yet started 4.24
cloud cobalt
Prepare to rewrite every single #include (or enable yet another "I don't want to update stuff" boolean)
Also quite a few depreciations
Including, aggravatingly, GetComponentsByClass
cedar snow
wat
dim plover
Since no one answered your question, UWorks isn't pre-compiled. It's my favorite thing about it.
cloud cobalt
It's not the end of the world, but stuff like that makes compiling a plugin on a newer engine a bit of a problem
cloud cobalt
Nope
I just compiled for 4.24 and took an hour or two to fix the includes, since the new way is a bit cleaner imho
Epic usually only writes the real release notes for the .0 release
dim plover
I don't think they even put small API changes like that in the release notes, anyway.
cedar snow
do you have an example for the header changes? renamed headers or something replacing minimal headers?
cloud cobalt
They removed subfolders from the default public header search path
So "UnrealNetwork.h" is wrong (should be Net/UnrealNetwork.h)
If you have folders in your game code, you'll have to write "Project/Folder/Subfolder/Header.h", too
dim plover
Oh... oh no.
cloud cobalt
There's a legacy option in build.cs for production projects, so don't panick 😛
dim plover
Well, might be a little late, but you know about Alt + Shift + Q with VAX?
cedar snow
i'am a no-vaxxer
dim plover
All you have to do is hit that shortcut on a missing type, press enter, and it'll automatically put the include.
cloud cobalt
Wondering how it handles situations like there where most of your old includes need to go away on top
dim plover
I'm pretty sure it won't take care of that, no. But 🤷 Intellisense squiggles should make it easy.
cedar snow
but why "Project/..."
cloud cobalt
It depends really
If everything is in one folder you're fine
If you have A/ClassA and B/ClassB though, include in B is "Project/A/ClassA.h"
They basically enforce the "Module/<subpath in public if any />Class.h" convention
cedar snow
at that point i just write a script to fix the includes @cloud cobalt
or get a demo version of VAX
cloud cobalt
I considered that, and using the easy bool
bIAmTooLazyForThis
(not the actual name)
cloud cobalt
Works too I think
cedar snow
i guess the reason for the change is disambiguation?
with namespaces generally not being a thing in ue4?
grim ore
@plush yew you are trying to set a variable for an item that is in the world in a class that is not in the world, you cannot fix this.
grim ore
is this item not in the world?
plush yew
ball is in world
grim ore
sorry are both items not in the world
grim ore
you have the item you took the screenshot of, and you have the item you want to put in that variable?
plush yew
yes both are in world
grim ore
ok then you should be able to set it on the variable itself not in the default settings
we can't see your code so we can't see where you are trying to do this at or what
plush yew
still trying to make that fk enemy
@grim ore
im going to jump from the roof if i dont get this shit work today
grim ore
click on the ball variable on the left, then you should be able to select it if this and the ball are in the world
but you are having all of these problems because you refuse to do step 0 and learn how this all works so shrug
grim ore
once you click on the ball on the left the drop down in the details panel should let you pick that variable in the world
plush yew
grim ore
you might need to do this from the item itself in the world, the instance of the item, i am guessing this is the player?

dim plover
What part in particular did you have trouble with?
plush yew
should this blueprint make my enemy move in x axis where ball named pawn is
there is problem because its not still moving
green lake
warped tangle
@plush yew Is that still just an Actor, because if so, then no, add movement input wouldn't move it. It would need to inherit from Pawn/Character
plush yew
its pawn¨
@warped tangle
oh god how hard it is to make just pawn to move other pawn
i have been trying to do this shit 1-2 weeks
nothing makes it move
warped tangle
This may be a stupid question...but do you have a floating pawn movement component on the pawn?
@plush yew
plush yew
no
warped tangle
Also understand that running that add movement input on beginplay is going to fire 1 time, moving it 1 time very briefly (probably not even far enough to notice). It needs to be run on tick/timer to have continual movement.
warped tangle
You need to have a floating pawn movement component
warped tangle
Also, I'm going to point out that using the actor location, and getting the X from that is not going to necessarily give you the results you may be looking for as far as direction goes
You want to use something like get actor forward/right/up vector depending on what you're trying to do
plush yew
@warped tangle still not working

@spark sonnet funny somebody else was having issues with that on here the other day, didn't follow the what was going on though
spark sonnet

warped tangle
@plush yew change the scale value to something like 100
warped tangle
is this being possessed by an AI controller?
plush yew
no
warped tangle
I think it has to be possessed to move as well
plush yew
the fuck is that
warped tangle
dude chill
plush yew
how to make it
i am angry because i have not made any progress in 2 weeks
nobody helps
spark sonnet
What do you want to achieve?
warped tangle
Hi all, I'm nobody 👋
plush yew
i want to achieve enemy thats move in x axis where ball is
very simple
@warped tangle how to make that controller
warped tangle
There's a default AI controller, just make sure that the pawn is set to be possessed by it
frosty bloom
I bet there is tons of tutorials just for this right here
warped tangle
click on it in the world, if it's already placed (I'm assuming here), and search for "possess", and see if AI controller is set to possess
There are, for sure
warped tangle
set the AI controller class to AI controller
warped tangle
set the scale value back to 1
warped tangle
also...I'm assuming add movement input wants a normalized vector right?
@spark sonnet
@plush yew just hard code 1,0,0 into the world direction
spark sonnet
@warped tangle I figured out my problem. Its a varible inside the function
warped tangle
Yeah it's probably because you're using get actor location, you should be using get actor forward/right/up vector
not location
warped tangle
should be
warped tangle
depends how you've oriented the actor in the world
plush yew
lol it was forward
it doesnt work anymore like it used to
i cant control it with ball too
why cant i use getactorloc
warped tangle
@spark sonnet have you had issues with pathing errors? I think that's what was going on with the other guy
spark sonnet
pathing errors?
warped tangle
he was getting pathing errors or something using find path syncronously
spark sonnet
My issue was that I couldnt get the path array
spark sonnet
But I found it
plush yew
now i need to just figure out how to stop this guy
warped tangle
@plush yew again, world direction expects a normalized vector for direction, not a location in space
spark sonnet
Thank you
plush yew
so do i use forward then @warped tangle
warped tangle
Yeah I have absolutely 0 idea about your game so I can't answer specific stuff
warped tangle
well yeah you're ticking a single direction movement input
the issue was you couldn't get him to move. Now he moves, now you gotta figure out how you want to handle the movement behavior
plush yew
it needs to stop when has same y as ball
and if it moves again, then it keeps moving
equal (floor)?
@warped tangle like this?
then when equal it stops movement
warped tangle
try it out, keep trying until you get it to work, then you can worry about making it work better
abstract relic
Man, it must go flying with that set up
plush yew
yes yes it just is flying outside map and i am now trying to make it stop when is in same location with ball
@abstract relic
...
abstract relic
Please do not ping
spark sonnet
Your stop movement is not connected to anything @plush yew
plush yew
oh
lol
how should i connect it
where should that white arrow thing go
from event tick
spark sonnet
You could use a branch to check
if its equal then stop, if not then move
But that would still cause issues I think
plush yew
i try
spark sonnet
How can I get the nearest vector to my actor? I found someone who made a function for it but its gone now
https://answers.unrealengine.com/questions/11133/closest-vector-in-an-array-of-vectors-in-blueprint.html?childToView=11135#answer-11135
warped tangle
@spark sonnet what do you mean nearest vector to your actor
spark sonnet
Get the nearest vector in an array *
warped tangle
ah, could loop over, subtract from actor location, get length, add to a temp float array, and get min value in array on loop completed?
plush yew
i understood problem
spark sonnet
There is a get path length (:
warped tangle
plush yew
warped tangle
@spark sonnet ^^
plush yew
should i put something to that scale thing
like there is in character movement
does it then know path length
can someone help me to stop this enemy to not fly out of map
its goes to right direction where ball is but never stops
warped tangle
you're never telling it when to stop
plush yew
i have no idea how to tell it to this asshole
warped tangle
unhook the event tick
warped tangle
then it won't move at all. You have to add some logic to tell it when to stop
I think youd be well served to do some tutorials and whatnot. There are a ton of resources online
warped tangle
now you have to give it a condition
plush yew
boolean?
warped tangle
right now it's always going to stop movement on every tick
This isn't a knock bro, but I really think you should go do some tutorials. You are missing some fairly basic programming concepts
plush yew
@warped tangle maybe i should have that boolean thing before going to branch?
what is the problem
warped tangle
that's expecting a controller as the target, either player controller or ai controller
warped tangle
honestly if you just put nothing on the true branch it'll stop moving as well, you don't need to call stop movement for something like this
warped tangle
yes, you need to give it a reference to the controller. In this case, it's the AI controller that's possessing the pawn
plush yew
okay
warped tangle
what does it say below in your compiler results?
plush yew
warped tangle
yes white == exec pin
true leaf
I think it means the input exec pin. The one on the left
warped tangle
I'm not at all sure what you're trying to do right now so I couldn't say
true leaf
It has to be connected to an event .. it has to be callable by something
warped tangle
so, as I said before, just have NOTHING on the false side of the branch
get rid of all the stop movement stuff you have
plush yew
oh okay
warped tangle
then plug the bool output of the float == float node you have into the branch
not sure it'll work but try it
don't start infernal
plush yew
plush yew
nothing in false part
abstract relic

We're here to help with problems like you had before where you pawn wouldn't move, but now we're in basic territory that you need to spend the time to learn
spark sonnet
Thank you @warped tangle That was exactly what I needed. I just used "Get path lenght" instead of subtracting it to make the code a bit cleaner

ah nice
I was just rambling off the top of my head lol
but yes that should work nicely

Also I just learned about the whole 'cast to is bad' thing and realized most of my bp size maps were over 2gb . My game took so long to load that the client would time out and not connect to the server when I pressed play . Lmao
runic iron
use tags when you can to avoid casts imo
true leaf
Spent time to put in interfaces and now it loads a lot faster but all my old code is terrible
Tags ?
runic iron
Yup, you can attach tags to your entities and just check if they have it with a simple "has tag" node
true leaf
Oh but that only works on literal objects in the scene I think
runic iron
Yup
true leaf
Most of my code deals w abstract classes , blueprints
runic iron
Oh ok nvm then lol
true leaf
Interfaces was the trick !
So now my bps send interface messages to eachother so they don't have to load eachother into memory all the time
true leaf
Yeah it's good for separating sections that are very different like ui stuff vs game stuff
runic iron
Definitely
true leaf
I found that it's almost impossible to decouple my unit class from my statcomponent class w interfaces but that's prob unnecessary
They should load together anyways I suppose
dim plover
If you had MyPlayerController class as a blueprint class property, would MyPlayerController be loaded?
pulsar kraken
I need some help. Does anyone know what you need for a projectile to explode on collision (not hitscan)???????
true leaf
Yes!! So that's why I always use playerController (the native one) in my code and use an interface to call stuff from GameplayPC (my custom extension of it)
I refactored so I'm not using GameplayPC directly in my other blueprints unless I absolutely have to
runic iron
I think the guy from the BP conference of unrealfest talked about that stuff
pulsar kraken
I need some help. Does anyone know what you need for a projectile to explode on collision (not hitscan)???????
true leaf
@dim plover those classes are a huge part of the story of reducing memory loading w interfaces. Usually they are the first thing to load and they glue things together so if you can reduce their sizemaps w interfaces that is big
runic iron
@pulsar kraken Didn't understand your question. Also don't spam pls
What kind of projectile are you talking about, we need more details
crude vessel
Oh no cast to is bad?
true leaf
Cast to isn't bad but if you abuse it you can cause memory loading issues
runic iron

@runic iron
true leaf
Think... Malloc
crude vessel
Define abuse? Like I have strings I cast to text for an error log
dim plover
What is the sizemap for your PlayerController blueprint, anyway? Shouldn't be a lot since PCs don't really reference any expensive art assets.
normal burrow
there is literally no way to not cast most of the time, you need to when you need to. you should avoid overly casting when you know what something is already though
pulsar kraken
@runic iron A projectile that explodes on impact with landscape. I have it exploding on actor collision atm.. I need landscape.
true leaf
Abuse meaning you put CastTo Unit nodes in a helper function library that you use in your GUI
Because then all your GUI BP's that use that helper library will need to totally load your unit class
Which is prob huge
dim plover
@crude vessel , That's fine. It's just BP class references will cause those BP classes to be loaded.
true leaf
Yeah what you described is fine since those classes are native and tiny
crude vessel
Okay, I'm still learning blueprints and want to avoid picking up bad habits because I'm new to it.
true leaf
You can click View>Sizemap on a BP to check and see how much crap it has to load to get rdy
runic iron
i think you have to mess with your collision presets @pulsar kraken
runic iron
pulsar kraken
have not seen that one.. i did however google for awhile.
thats probably it because i don't even know where collision volume is in 4.23
sigh so simple yet so tough
runic iron
Isn't landscape an actor too ?
pulsar kraken
landscape is a landscape
runic iron
pulsar kraken
If your talking about "type" atleast
runic iron
Seems to be an actor too
pulsar kraken
runic iron
i don't use them but it should be registered as a hit actor like your other actors so I think the problem comes from your landscape physics presets ?
pulsar kraken
icy mulch
Can you use soda brands in games yes or no
true leaf
No . See: nuka-cola
runic iron
Seems that you don't have the "simulation generates a hit event" with a landscape @pulsar kraken
true leaf
Just make up a cheeky fake brand
runic iron
Maybe the problem comes from here
Cause on other actors
Again I don't use landscapes so I'm not really sure about that unfortunately.

Where can I send invitations to this server?
grim ore
alot of the time overlapping UV's for that much is due to similar faces being overlapped, like a cube for example with each side actually overlapping in the UV map instead of being seperated in islands. You can try and reimport and let it remake the UV's or you can unwrap it better in the DCC program. visualize it with a texture perhaps so you can see which part of the mesh maps to which part of the UV Map @pseudo swift

dense gate
So the game Paragon was closed down with most of its assets released, now the projects that spawned to "revive" it are willing to ask money for microtransactions of the included skins
Is there anything in the Epic TOS/EULA that would disallow them from charging for such a thing?
plush yew
@west basin That is the relative path to the starter content in teh engine, so if you don't have it on your engine, then you'l find it on teh github on that relative path
@dense gate No, like any other asset you buy and get from epic you are free to use it however, I mean it'ss bit douchy to charge microtransation for skins, even more so when it all was free I would say, but anyone is can use them how they see fit if they so chose

Does someone know how to export textures correctly from World creator to UE4? It doesn't work in my case.
placid yarrow
I previously asked about the best way to give the user 20 or so possible avatars (each with their own meshes and animations), and based on some good advice from @normal burrow, I created a bunch of data assets that each have soft pointers to one skeletal mesh, one anim blueprint, and about half a dozen anim montages. I'm assuming that I will now have all 20 of those data assets sitting in memory during gameplay, but I'm hoping that they are relatively small. Is it fair to say that, because the variables inside the data assets are all soft pointers, the data assets that aren't being used are taking up relatively small amounts of memory? If I'm wrong, would I be better off creating a separate blueprint class for each avatar (instead of a separate data asset)?
normal burrow
Kelby, yes data assets should be tiny. its more about the references they have and because your using soft references to the memory large stuff those won't need to exist before the data asset
you're basically going to have your data assets in memory at all time which is ideal. Unless you are getting them from http or some external source.. having many data assets with soft pointers should work just fine.

ok
well can you recommend me a video on just using c++ for ue4?
i wanna learn blueprints and that

Never found one at the time I needed them. Might be different now. From unreal itself there is nothing that will help you.

There are C++ from Unreal, but they don't explain all the UPROPERTY UCLASS stuff. They just call some functions but don't explain the specifics about unreal

Struggeling myself with lighting currently, but for Oculus Quest
you know what the build button is for (Build lighting)? I would assume it to bake the lighting into the lightmaps of the objects. Only thing that happens is that the scene looks completely different after pressing it

probably how many uobjects there are s-ed
next badger
that's default start map...
and for some reason it increases
normal burrow
ye, i mean, keep in mind when you define a range in a particle random thing, thats a uobject lol
there are lots of uobjects
next badger
6,479 already...and it was idling in BG
i know...but...why it keeps increasing while nothing was done

normal burrow
maybe its loading objects in the background or something

Does anyone have documentation on how to import VDB files into unreal? I saw online people saud proxylod supports it but i don't see anywhere that explains how.
abstract relic
first and for most. Do you have the bridge plugin (it's name eludes me at the moment) installed? In both Houdini and unreal
visual belfry
@next badger that's been there for a looooong time, it just shows objects that the garbage collector is tracking iirc
thorny locust
I don't no
I wasnt using Houdini i had bought vdb clouds online
Do i need Houdini?
blissful trail
when i load things it sometimes just crashes pls help i just lost like 14h of unsaved progress with an ai i was making
abstract relic
Nah. That was presumptuous of me.
thorny locust
no worries
abstract relic
Going off of memory for your case. I think you get openvdb into unreal in a round about way. Use ProxyLODplugin
thorny locust
@abstract relic right so I'm using 4.23 installed and have ProxyLODplugin turned on but do you know the next step
normal burrow
https://vimeo.com/211875459 found this but idk if this is vdb
not real descriptive 😂
thorny locust
@normal burrow yup I saw that one looks like he is hacking it exporting multiple 2d sprites and remeshing them togther in ue4
I don't really know Houdini though
abstract relic
Ah, you want to make a ray marching shader
thorny locust
so ray marching allows vdb?
normal burrow
it might involve converting your vdb to something else jonathan. but i don't know, am kinda interested now
thorny locust
I see
abstract relic
here's a useful link for that rabbit hole https://www.youtube.com/watch?v=CWzPP5FAYAg
normal burrow
thorny locust
Yea I peeped that earlier but it seems that plugin isn't in development anymore it stopped at 4.17
abstract relic
Ah damn. I do apologize Jonathan, Houdini's game tool is the only method[s] I'm familiar with.
normal burrow
I take it you tried just importing the vdb with import panel after enabling the plugin jonathan?
thorny locust
Yea no worries at all thanks for even taking the time
@normal burrow yea first think I tried
normal burrow
ye, hm that would make me think they don't really have means of storing it in uasset
thorny locust
yea or it might be to memory intensive for it to handle
but yea when I drag n drop I get that error in the lower right
normal burrow
kinda doubt that but perhaps. tend to think they just don't have a proper representation class for it in the engine. First time i've heard of the format tbh
might have to use houdini to convert it to something usable
openvdb has something with maya as well
thorny locust
yea most 3d apps can use them but I wasnt sure about game engines
normal burrow
quite an extensive format https://github.com/AcademySoftwareFoundation/openvdb/tree/master/openvdb

thin tendon
Does anyone know if there is any Unreal documentation for the more technical stuff? Like what are the size limits of arrays or how many sample nodes can I have in a material.
normal burrow
Array size max is likely 2147483646
You just have to read the source code for a lot of stuff.
For samples it’s likely gonna be whatever limitation sm5 has
thin tendon
Well I just found out that the limit for a material collection array is 1024 which is way under what I need.
And now I am starting to hit limits due to the scale of my project some official documentation would be nice
normal burrow
Material parameter collection?
thin tendon
yeah I have a Material paramater collection and the array I am talking about is the vector array
Not the scaler one
normal burrow
thin tendon
thanks
normal burrow
Scalar is 1024 too
thin tendon
Yeah I just spotted that. I might need to rewrite my code to use more then one material parameter collection file
normal burrow
Curious what your doing with that many vectors lol
thin tendon
I'm working on a system to cull rain for objects that are created at runtime and have the whole thing working using materials. Because all the methods I have seen so far don't work with objects dynamically created at runtime
normal burrow
Volumetric vector parameter cloud?
thin tendon
What I am doing is storing the absolute location of each cull box. And then in the material for rain saying that if it exists in the same space as a box turn it invisible
normal burrow
“ It” as in rain particle?
thin tendon
Yeah
normal burrow
If your using c++ you might want an rwbuffer for it and some hlsl.
thin tendon
Nah I'm using blue print for my first project. It was so I could better learn the limitations of blueprint and unreal
Also the added benefit of blueprint is anything cool you make you can sell on marketplace later
normal burrow
Hm yea updating 1024 vectors in bp per frame would be quite a lot of processing. But could be done I suppose
thin tendon
yeah I'm still figuring it out. I will probably come across a bunch of issues before its done
But from what I have seen in other areas of my project is driving things with materials usually ends up cheaper on performance
abstract relic
Do keep us informed. That sounds like an interesting endeavor!
thin tendon
Will do mate 🙂
plain tiger
Can you set location of vertices in a mesh already loaded in unreal with bp? 'not on staticmeshes'?
peak crane
What is the name of the reversible (horizontal) compass?
plush yew
Do blueprint runtime errors actually affect performance in any way?
Outside of the fact that you're executing code that does nothing
Like, does the fact that it's an error specifically make the performance worse?
normal burrow
Do errors have purpose is the question? Some errors will stop execution. Others mean your spending processing time wastefully
plush yew
Like, I cuold stop these errors by putting down an isvalid node
but would that really be any better than just letting it send error codes
normal burrow
Correct having None as far back as you can and the value increases. But yes you don’t want to have code that errors like that. Errors are logged and that’s slow. Much slower than is valid
plush yew
Are they logged in a packaged product?
I guess it doesn't matter, I'm going to be getting rid of them now anyway
thanks p@t!
thin tendon
@plush yew Any warnings are ok these show as yellow. The red ones that are actual errors you want to get rid of. Because the engine uses extra resources trying to decide how to handle these and if it should ignore them
plush yew
Thansk @thin tendon
thin tendon
With these parameter nodes it gets them as a float. Does anyone know if I can get them as a float array? So that I don't need to add nodes for each and every single entry.
I know when not in materials I can convert to array. Kind of wondering if I can do it inside a material
thin tendon
@pulsar kraken Instead of using that. Create inputs the the axis mapping. Have an axis map for each mouse axis (x and y). Then on each axis map have a keybind for both a positive and a negative. Then in your code thier instead of calling mouse press. Call your axis mapping. You won't need to negate it or anything just plug it straight in
pulsar kraken
for some reason even when i did it that way.. it would work but the rotation would lag in multiplayer
(run on server + replicate)
thin tendon
Not sure about lag but thats the way to do it. Maybe try replicating to client or multicasting them
pulsar kraken
did that too
another thing i notice is when trying to move the mouse without the server.. it snaps back to the middle of screen slowly?
thin tendon
Sounds like it definitely needs to be replicating to the server then.
In that case I would try looking at your rotation code and seeing if you can simplify it. So its processing a little less each time.
thin tendon
Instead of add relative roatation try set actor rotation
pulsar kraken
yeah i did but it doesnt work
hmm.. it moves.. then moves it right back to center of screen..
thin tendon
I'm not sure then because mine looks like this
pulsar kraken
like automatic
thin tendon
But I don't use multiplayer
pulsar kraken
multiplier is just for inverted
this will move the rotation.. BUT... it snaps back to the middle of screen?
thin tendon
Maybe try adding something to it to say when it is and isn't allowed to rotate the player
So after your finished rotating the player there is something to stop it moving back
dusky inlet
anyone know why the fbx exporting from UE4 is so broken (at least using Blender to import again)?
thin tendon
blender adds leaf bones and uses a different orientation and stuff. Max or maya will give you better results
dusky inlet
leaf bones can be disabled at least. No clue about orientation 'n stuff since I haven't tried rigging/animating yet.
The one thing that irks me is the ue4 export functionality. Exporting morph targets seemingly destroys the setup material slots and also doesn't give me the morph targets, using Blender. Maya seems to be fine with it <_>
mint thunder
Hi guys, is it possible to remove the color from a decal material instance?
fierce tulip
desaturation node with variable?
mint thunder
all the things i tried result in a black color, and i just want to have a normal map only, in one instance
In this decal instance i want to remove roughness and color and only keep a normal map texture
fierce tulip
why not set up a proper material for that?
mint thunder
i don't want to keep making master materials, i have one and i'm modifying it
i tried a static switch parameter but leaving an empty slot returns an error
mint thunder
yea but all the values return black color
fierce tulip
if you dont want roughness, in the "use roughness false" put a 0 or 1
not i you do it right
a switch is nothing more than changing the branch
so it needs another branch, not an empty slot.
mint thunder
if true is the color and false is 0, it returns black in the color slot, and 0 in roughness results in completely shiny material
mint thunder
so i guess this can't be turned into a parameter
fierce tulip
there should be some options in instances, but I dont play much with decals.

Hey, hope yall are doing good today. I am working on lighting a procedurally generated interior scene and I am using a directional light, skylight and postprocess but the results aren't good enough. If any one has worked on something similar can you please share your research.

by this way image are white
i made menu map and when i start it, my game character drops from nowhere
how to fix this?
sharp crest
@short plaza but I did, the error is coming from the is valid function lol
raw patrol
@plush yew just setup a player spawn and put something under it
plush yew
i already fixed it
raw patrol
Oke
proper quiver
@fathom gust generates scenes can’t bake lights so you have to rely on good real time light positions
Or go full ray trace. Perhaps the new 4.23 real time screen spaced ray trace would help
Specifically your screenshot though the direct light source direction isn’t clear and there’s no shadows
I would begin by adjusting those. And the AO as well
fathom gust
Since the level is generated procedurally I cannot place lights(point,spot,etc) there's a default Directional light with skylight and postprocess. The Directional light is almost at an angle of 90 degree from the ground. Most of the scene is lit because of the skylight. And AO is there because of post process
proper quiver
Why can’t you procedurally place lights?
Also yeah what you are describing will get you those results
fathom gust
From what I have researched its going to painfully unoptimized if I use point lights and such.

you run into precision issues even at 1km
if you have camera on a chain of transforms

dim plover
UnrealEngine-4.21\Engine\Programs\UnrealPak\Saved\Logs For me.

Hmm, my 4.21 has it but my 4.20 doesn't. Maybe you had to have packaged (maybe with Frontend) for it to be created?

@manic pawn - looking at trying to get away with not compiling those Apex DLLs, but they seem to still be included
bCompileAPEX = false in my TargetRules
and as per your suggestion I added if (Target.bCompileAPEX == false) { return; } in APEX.Build.cs
but it's still being compiled
(and included)
manic pawn
that's strange
wary wave
yeah
manic pawn
you set it to false in the target.cs for packaged too right
wary wave
in UE4Game.Target.cs
hmm, maybe not in the individual project, it doesn't have a C++ project set up
manic pawn
I just changed the default to false in TargetRules.cs
and added that branch
and it removed the libs for me

New Scary Material Node
waxen narwhal
Hey, is it possible to kinda implement a Live data source in Unreal Engine and let the environment react to it ?
So for example based on the state of the data, some lights should be turned on. If there is another state, they should turn of
kindred viper
of course. It would be a pretty bad engine without data driven gameplay 🙂
fierce tulip
so, 4.22 feels so much slower when it comes to live updating materials.
kindred viper
yeah looks like material layers are having a comeback in 4.24 right?

yup

@desert jay I don't mean to continue this disagreement, but if you are talking about him buying the character model (or else I'm confused, I think that's what you're saying, right?) he didn't buy it, it has come from our character model, and Doggo here is rigging and animating it.
