not fast enough, there are some inneficiences
icy bone
lol
reminds me of when i was making games in DirectX and OpenGL
the code was too ugly i didnt wanna recognize as mine
frank escarp
maybe i go help the godot devs a bit
they really have issues with anything perf related
@icy bone their new third person shooter demo?
12.000 drawcalls
not even 30 fps, on a GTX 2080 plus a overclocked ryzen
CPU usage doesnt go past 20%
tall pendant
making pubg nice? so deleteing their p4? 😄
icy bone
drawcalls are evil
frank escarp
@icy bone with the nvidia turing architecture stuff, you can literally delete drawcalls
and dont launch them
frank escarp
only 1 drawcall per material
i need to experiment with that, that stuff is wild
@icy bone they let you generate geometry from a compute shader, its a bit like instanced drawing + geometry shaders multiplied by a thousand
icy bone
nice, im not familiar with that, but the bottleneck between CPU and GPU has been too long
frank escarp
so you can just have your scene meshes and scenegraph on the GPU, and batch-render per-material
including culling
done in the gpu
icy bone
cool, so u can push into GPU ur entire Geometry library and decide what to do from there?
icy bone
nice
icy bone
ye having Geometry on the CPU for each mesh etc is just stupid
frank escarp
and its basically gpu batching
icy bone
i guess this is possible because of GPU are more General Purpose now
frank escarp
yes
icy bone
u can do more than just math logic
frank escarp
its a new type of shader
that replaces vertex/tesellation/geometry
nw oyu have "task" shader, and "mesh" shader
icy bone
CUDA shader XD
frank escarp
both of those are compute shaders, with compute shader features
icy bone
task shader sounds interesting
frank escarp
the task shader emits mesh shader invocations
and the mesh shader fills a vertex array that then gets to rasterization
icy bone
this tech will be awesome
frank escarp
that vertex array gets sent to the rasterizer
nvidia says, that even if you use it the "dumb" way, it goes faster than the normal pipeline
icy bone
btw anyone tried Niagara? it seems so awesone, pure GPU, i have yet to try it
frank escarp
due to being more efficient with gpu compute
icy bone
nice
frank escarp
consoles will have that tech
for the next gen
its not only from nvidia, AMD also had their own version of something very similar
it skips the fixed pipeline primitive assembler
icy bone
ye ofc, both companies probably have "coffee friends" working at the other counterpart
frank escarp
you just send the mesh data in whatever format to the gpu
icy bone
to have coffee discussions
frank escarp
and the compute shaders emit triangle lists
how you emit those triangle lists doesnt matter at all
so it can be procedural too
icy bone
sounds very cool
i wonder how Unreal4 will update their material editor for this
currently its just fragment and vertex
frank escarp
they dont need to
you can just use this on the background
and basically you get perfect automatic batching
icy bone
i mean to UE4 can allow people to utilize this new power without wirting shaders
frank escarp
they can use this no issue
probably will, once PS5 happens
as PS5 will have something similar
icy bone
now u can set vertex position offset, and fragment processing
but u cant generate geometry from material editor
but they do use computer shaders for Niagara tho
frank escarp
thats fine
the mesh shader stuff would be GODLIKE for particle effects (niagara)
becouse you can do both the compute shader for moviement, and then emit the triangles from that compute shader
icy bone
yes
sometime i feel like UE4 is very good for Artist and "hardcore coders", but nothing in between
u either need to be quite solid coder or just use BP
plush yew
What did you guys think of this article about camera lag in UE4? is this a way to fix it?
https://www.gamasutra.com/blogs/FabricePiquet/20180621/320400/True_First_Person_Camera_in_Unreal_Engine_4.php
Avoiding frame lag
I didn't mention it yet but an issue may appear. If you follow my guidelines and are not familiar with how Tick() functions operate in Unreal Engine, you will encounter a specific problem : a 1 frame delay. It is quite ugly and very annoying to play with, potentially creating strong discomfort. Basically the camera update will always be done with data from the previous frame (so late from the player point of view). It means that if you move your point of view quickly and then suddenly stop, you will stop only during the next frame. It will create discontinuities, no matter the framerate in your game, and will always be visible (more or less consciously). It took me a while to figure out but there is a solution. To solve the issue you have to understand the order in which the Tick() function or each class is called. By default it is in the following order :
_____ UpdateTimeAndHandleMaxTickRate (Engine function)
_____ Tick_PlayerController
_____ Tick_SkeletalMeshComponent
_____ Tick_AnimInstance
_____ Tick_GameMode
_____ Tick_Character
_____ Tick_Camera
So what happens here ? As you can see the Character class updates after the AnimInstance (which is basically the AnimBlueprint). This means the local camera rotation will only be taken into account at the next global Tick, so the AnimBlueprint use old values. To solve that I don't call my function "PreUpdateCamera()" mentioned before into the Character Tick() but instead at the end of the PlayerController Tick(). This way I ensure that my rotation is up to date before the Mesh and its Animation are updated.```

frank escarp
meanwhile in rust-land i get cargo
wich is so awesome...
make a rust project, and i automatically get an amazing package manager + crossplat compilation
if i want a library
icy bone
never tries rust
frank escarp
i add it to the [dependencies] part in the cargo config
icy bone
but i like GoLang for small portable programs
frank escarp
and it installs it and links the lib
some libs that depend on C libs (like SDL) still require you to grab the SDL Dll and put it in your project folder
but still, better than C++ and adding the include paths, lib paths, etc
pure rust libraries need no work
add to dependencies, and they get downloaded and linked
frank escarp
same as C/C++
icy bone
i used to use python for all kind of tools, but its portability is shit
frank escarp
so yeah
icy bone
thats cool
frank escarp
its basically a C alternative
you can even have it not add the STL and create ultra-small binaries
(compiled lenguage)
im trying to learn it better, as its a great lenguage
made a chip-8 emulator with it, porting my C++ version of the emulator
frank escarp
feel free to have a look at it, i made it as a example of a hybrid project
it was made in 1 day
second day used to polish it a tiny bit + clean the code up and document
icy bone
i did
im currently making a game for my company also

lemme get a link
see recomended landscape sizes
@west bane I've used saga gis' b-spline interpoloation which worked fine
Ive also scaled up in GIMP and did a gaussian blur, less fine but you might like it?

But there is standing 254x254 is that cm or something else the size
supple totem
it is meters paly
And you're thinking it's cause a poor interpolation method?

Hi here, when you create a proxy for an actor, an Ai in particular, do you destroy the Ai and spawn a simplified actor instead?
Or do you keep the same actor but you just remove the skeletal mesh, stop running the behavior tree, stop ticking, etc...?
I'm using the first technique and It's becoming complicated with all the values I have to pass on to the proxy in order to keep them somewhere (like health, referenced actors, status, etc...)
whole quarry
Strange, by default it should work. You mustve changed something
chrome summit
trying to find when you change the mobility of the camera

@plush yew Google: UE4 How to chop a tree
plush yew
Anyway, you could create a tree and different more damaged models of a tree (the more you chop it, the worse it looks) and whenever you chop it... it drops an item that you can pickup
I searched it i another way
thank you @whole quarry
thank you again
and one more question how to search for: how to open chest in ue 4? to make this way and to store things?
Are you serious right now?
How about you first learn the fundamentals of blueprint.
And the basics of 3d modeling and 3d animation :)
Because what's next? Are you going to ask for a tutorial for every single thing you want to add to your game?
if you knew the fundamentals of 3d modeling, 3d animation and programming (or blueprint) you wouldn't be asking how to do those things.
Right now, you are looking for shortcuts that might not quite exist and won't help you understand how to do any of it

In previous inventory systems I've made, I've used arrays of structs for storing info/data on the items I've got in my inventory, and then pulling data from a data table if I need more info for it
but several tutorials spawn actors to hold the data for the inventory system, blank actors with Name, count, etc..
I always thought that spawning lots of actors for the inventory could become a memory hog or something...
I'm doing an RPG, and the player might end up holding a few dozen to maybe a few hundred items (hopefully not) in their inventory...
thoughts?
frank escarp
fuck, not Actors
dont fucking do that
the best thing to do is use Structs
they are the fastest and easiest to deal with
if you really, REALLY need OOP, then UObjects
never use actors
opal ocean
Hehe ok.
frank escarp
actual recomendation, just use structs
you can have a pointer to a blueprint if you need it
opal ocean
Array of structs? or should I store in a Set?
opal ocean
I'll go with array, cause I dont know how to use Sets 😃
icy bone
if ur stuff aint gonna represent anything in the game world
use UObject or Structs
UObject preferably if u wanna pass pointers around and have GC do its magic
opal ocean
Naw. Armor is just going to be stats on the character, the weapon and consumables will be handled once equipped/used
icy bone
@opal ocean Array is good, but remember to check for duplicates... Sets are kinda better for handling uniqueness of stuff. It is also very fast for finding duplicates etc
opal ocean
Yah, I made a DoesItemExist function already
icy bone
problem with array is when u remove stuff, things have to move around which cost performance
opal ocean
I dont know how Sets handle structs, as it only matters for the itemname and item type
frank escarp
so dont bother about algorythm complexity
"linear search everything"
who cares, if the array is small it will be the fastest anyway
icy bone
@frank escarp agreed
frank escarp
and its the simplest to code
btw, for this stuff, check Algo
it has stuff like "filter if", "find" ,"sort" etc
opal ocean
linear search? I do a ForEachLoop and check if itemName == itemname, if it does, return the index
frank escarp
thats linear search
icy bone
for small stuff use TArray, it is the most supported class. Like UPROPERTY etc. Other stuff may not be so well supposed
supported
opal ocean
I'm doing it all in blueprints, so I'm probably a bit limited that way
icy bone
then doesnt matter
use what u like
😄
since ure not making mobile game so u wont need to think of performance too much
just spam stuff brute force, and optimize later if it becomes promising 😄
opal ocean
My main issue is simplicity of programming 😄
next concern is speed of development, I want to get a playable game sooner rather than later!
icy bone
then BP and brute force is surely what u need
frank escarp
@opal ocean https://github.com/vblanco20-1/HoverGame
read the written stuff and have a look
hybrid arch, fastest you can get for making a game
much faster than pure blueprints or pure C++
also
plush yew
Im not new to programming, but I'm a bit new to structs. Why would you use a struct instead of a class?
icy bone
i code alot of the core in C++, and expose it to BP for simplicity
frank escarp
those lines show how to use the array .sort function, wich takes a lambda
you WILL need that
icy bone
in C++ Structs and Classes are actually the same...
frank escarp
@plush yew no allocation, gets sent by value, gets stored inside an array or similar
plush yew
''its just by convention that struct is used for data storage''
Is it a problem if you use a class to do this?
icy bone
no
plush yew
Or is a struct lighter?
icy bone
all up to u
smoky stream
structs are public by default, classes are private
frank escarp
USTRUCTS are different than UOBJECTS by a huge difference
smoky stream
thats it
opal ocean
that snippet is to choose target?
icy bone
struct used to be lighter, thats the idea, but these days they are exact same as class
plush yew
ha oky
icy bone
structs have public, private members and methods
but in UE4 the UObject class is the base class of most things, so use that if u want to utilize UE4s refelction system
but in pure C++ its the same
lol

@icy bone IIRC the only difference is raw C++ structs default public. USTRUCT and UOBJECT are obviously different though
And of course they're very different in C# -- value vs reference type.

guys how can i do it ?????,
bleak copper
I don't know what you mean "if the player camera view" -- you mean if the player camera is looking at a given actor and nothing is blocking its view?
bleak copper
@plush yew Hrmmmmmmm. If it was me, I'd do it in C++ and expose it as a blueprint node. Call it "check can see (blah)" or whatever. Take the player camera as an input. See which direction it's facing and its horizontal and vertical FOV. If it's within that truncated pyramid, cast a few rays from camera to object to see if they collide. Maybe one at the four corners and one down the center? Uncharted 4 did one ray per bone from the AI's head to the player's skeleton for player detection.

any other devs who have game in steam who got this tab (under marketing and visibility) ?

that's prior to spectre and meltdown patches

for the lightbuilding
that will all change if UE4 gets GPU lightmapper soon
right now, intel CPU's hold advantage with lightmass building due to the intel lib being used for it
but that advantage will go away when moved to GPUs
well, there's no official promises about gpu lightmapper
so don't rely on that 😄
it's just very likely thing to happen

hi all
my project performs smoother in windowed than full screen
why might that be?
My current theory is screen sized based LOD adjustments?
wary wave
stupid question, but, is the window a different resolution?
supple totem
its a good question
the window is def 720p
full screen honestly looks too crisp
but its the reso I put in the ini
wary wave
full screen will use your native desktop resolution, I believe
though I'd have hoped the ini files would override that

windowed fullscreen always uses desktop resolution, can't change it
exclusive fullscreen uses the resolution you set

Question: is there a performance difference on spawning new particle emitters vs. resetting existing one?
if said emitters lifetime is <0.2sec
regal mulch
Anyone ever used the "LoadLevelInstance" event either in C++ or BP?
It seems to cause GameThead hitches, even though the actual LevelInstance is relatively basic (few StaticMeshes and ISMC).
Now as far as my Profiling skills go, I assume as long as the GameThread spikes together with the other threads, it's only GameThread code related and the actual drawing of these new Meshes isn't even the problem.
I would also guess so based on how basic the level instances are.
paper kernel
could be an IO hiccup?
regal mulch
Well it's always when the new Levels are spawned
I think currently it's 7 LevelInstances
Do you mean FIOSDeviceHelper? @paper kernel
Despite that I can only see TaskGraphs, which I obviously don't know what they do in specific
paper kernel
I meant it's probably accessing something that is being fetched from disk
which could cause hiccup without actual performance loss
regal mulch
Wouldn't that stop if the Levels are loaded once?
The second time they should already be loaded from the disk
paper kernel
no idea does the engine keep it in the memory
regal mulch
No idea either. I would love to know what causes the hickup based on UE4's profiling tools :/
So, looking further into that, it seems to cost a lot to just load the level and register all the components and shit
paper kernel
why does LFTalent channel have unity job postings?
regal mulch
wow. LoadLevelInstance, with an empty level, drops fps and causes a GameThread spike -.-
Guess I can forget using Levels as "Instances" then. If only UE4 had proper Prefab support
frank escarp
@regal mulch have you tried the prefab plugin?
regal mulch
I have looked at it but I'm not sure what it exactly does
For me a Prefab also needs to keep the relations between two or more class instances
Yet to figure out if that plugin supports that
Prefab is an editor tool to help level building, it can't be spawned in runtime.
I need it to spawn Runtime
frank escarp
it has a "convert to blueprint" button
i use it in my procedural dungeons
becouse its a bettter way to edit the rooms than to use the blueprint editor...
regal mulch
Well that sounds like it won't keep references between two actors, does it?
We don't only have some meshes and independent actors in the level.
There are also e.g. Button Actors referencing Door Actors.
And that connection needs to persist.
I feel like UE4 is just not made to spawn a bunch of actors at once
We converted the level to a BP Actor (minus the actors in it, so only meshes) and while this improves the situation, it still spikes
And that's still GameThread spike, not even render as these are only a few blocks per spawn
static viper
mh
regal mulch
Could further optimize by spawning instances of an ISMC, but at that point we lose the ability to properly plan out a "prefab" of a level tile

how much you spawning?
there is always a spike at start
i am spawning lots of things in with my save system
actors
regal mulch
It's not the start
static viper
i feel like this is something i will run into aswell with streaming
regal mulch
It's throughout the game. We preplanned level tiles via ULevels and loaded them as instances.
But loading instances, even empty levels, causes frame drops cause of the GmaeThread spiking
Profiler says the ULevel being constructed and Serialized is one part of the problem
So to get away from the ULevel problem, you'd need to save your constellation differently. UE4 has no prefabs, so you need to put that stuff into Blueprints.
Which we did now, but spawning 7 Blueprint Instances with like 10-20 meshes in them is still dropping frames cause of the GameThread.

Good morning everyone! Assuming you live somewhere near me.
Forward rendering does not allow dynamic lights, correct?

nope. it allows dynamic light.

Hello guys I need help
I must when I write in the bp: "get info at index" to show me this:
but it shows me this:
wow
why?
dim merlin
Hi, i added a FloatingPawnMovement component to my pawn, but i use AddControllerYawInput the pawn seems to start moving.. anyone knows why?
frank escarp
@regal mulch the issue with ue4 spawning, is that you cant do it async (i think), but even bigger issue, is that it has to load the assets i think
the first time you spawn something its likely to bring a ton of data with it
regal mulch
Yeah :P we will look into other things instead of UE4 for this
UE4 is sadly not the answer to all
@frank escarp
supple totem
this is probably a very specific question, but no harm in asking:
im using merge actors to put a cube beneath a tree
the tree is a speed tree from the marketplace, with nice wind animation
when merged, the tree loses its wind animation
in the material graph, the speed tree data is still wired up
anyone have ideas what might be going on?

I can't find the documentation for this project anymore https://youtu.be/_XyjMeAb3fw
I think it was here, but now that the documentation has been updated, it's hidden or deleted https://docs.unrealengine.com/latest/INT/Videos/PLZlv_N0_O1gYqSlbGQVKsRg6fpxWndZqZ/abmzWUWxy1U/

ok thanks, will see what I can figure out
ah damn, looks like speedtree might have some black box magic going on https://forums.unrealengine.com/development-discussion/blueprint-visual-scripting/1495004-attaching-a-mesh-to-speedtree-with-wind
modifying the mesh in engine breaks stuff
ok so....
maybe I make a blueprint, that scans a given area for my instanced tree meshes
and for all it finds, places a cube at their base
sounds feasible?
earnest cape
Well I found an old version of the steam project and it still doesn't build. Did they change something about the online subsystem steam plugin?
Maybe generic shooter still works with steam

we're locking, or want to lock, our game at 30fps, but doing so makes music in our cutscenes go out of sync - any idea why this would happen - is there a better way to cap framerate - locking sounds incorrect but might be terminology thing

after the delay respawn doesnt work
but if i remove delay it works fine
i tried to add a print string after delay to say hello and it doesnt work its like it has a delay forever
earnest cape
Why am I getting this error?
chrome summit
@earnest cape cant read those letters
earnest cape
I guess it's something to do with visual studio

It's weird because 2017 is installed
I'm uninstalling 2013 and 2015
maybe those were breaking it

Will do. I'll post here if anything lights on fire

@static viper can you help me with something

Anyone ever encountered "GPU has crashed" ?
cloud cobalt
One of our clients had the problem, denies any overclocking
smoky stream
you may be doing something really weird with the GPU then
its very difficult to crash modern drivers
grim sinew
Or it could just be a GPU problem

We're not doing anything weird really
Well,I guess we'll keep the negative review about his GPU being fine and us terrible devs 🤷

Hey, I am using Steam in ue to get the multiplayer, its working and all, but my problem is that only the host can move, but the other player cant. Can anybody help? Thanks
novel ember
I know you can get around the same issue in the Panner, but for the Sine node is it possible to change its rate / frequency without resetting the sine itself?
like this
because as-is trying to change the sine seems to reset it immediately causing a flickering effect
magic flame
So why ue4 need shit ton of time to launch ?
versed spear
If you open task manager you will see that is it is still loading everything. This will only happen the first time you load a project.
magic flame
I got a lot of project's all effects test
flat marlin
Hey guys so im setting up animations outside of UE4 and i was wanting to know if it was better to parent the gun to the hands or hands to the gun.

you need to migrate from one project to the other?

I need ue4 render
I work in blender u know
And used to be active in old game maker sandbox xd
vivid girder
If I need a class to serve as a TaskManager for my Pawns (distributing out what work they need to do) should I use a GameInstance or GameState?
This class would need to be local to the client (multiplayer game)
But also easily accessible from any instances, like Behavior trees and controllers
But it'd only need information specific to 1 client
versed spear
You say it needs to be local to the client but it is going to process on the server. (multiplayer game) You can not have access to it from the client but you can replicate back to the client. The client would send request and the server would do the work and replicate the results back to the client. I have been messing with a server client inventory system and I had to write new custom events for the server and client communication. Still learning though.
vivid girder
I don't need it to exist on the server at all
It can be totally local to the client
I think GameState is what i'm looking for
pallid compass
If you make a MF and you want to pass in a texture, how do you break it back out on the other side so u can access the UVs and such?
vivid girder
parameters
However if you're passing in a texture you can set the scaling before passing it in
pallid compass
Well yeah
How do u break it out a param
to be accessiable similar to a text
and also make the MF output a text
vivid girder
If you have to pass in the texture and change tiling afterwards you can feed it into the Tex input of a texture sample
pallid compass
instead of v3
vivid girder
What are you saying
pallid compass
Texture goes in > access to Uv's > texture goes out not float3
vivid girder
pallid compass
Thats still a vec3 output
vivid girder
Pretty sure a texture object doesn't support dynamic tiling
It's just whatever the raw texture is
pallid compass
Im not after tiling, i havent mentioned tiling
vivid girder
You're manipulating UVs, right?
pallid compass
Yes

can u seperate two masks of the same colour if they are seperated by another mask in material editor? ie, if its a black circle, white on the outside, white on the inside

I'm trying to figure out how to store data for spells that can be created and deleted on the fly. I thought about using Maps, but I can't figure out how to create and delete them from inside a graph. I would want to store data somewhat like this.
{
"SpellName" , "example"
"Duration" , "10"
"MPCost" , "5"
"Power" , "4"
}
and so on and so forth.
Does anyone have any idea what I could use to accomplish this?
autumn swan
@velvet forge if you mean storing this data to unit a class with, you could use DataTables
No idea how to do it via Blueprint, but I use C++, DataTables, and an external CSV data file generated from Excel.
Unit = init
velvet forge
Oh yeah forgot to mention I'm in blueprint
autumn swan
Should be examples of how to do this in Blueprint
native pawn
anyone know how to make animations if your a beginer?
autumn swan
@plush yew good question. I work for Blizzard Entertainment, and we have a Side Projects program. For me to retain rights and to minimize and legal backlash for Blizzard, they have me sign a contract regarding the rules of the Side Project program. For the most part it indemnify’s Blizzard so if I get sued they can’t be held liable. There is also a right of first refusal, so if some company wanted to buy my company / game out right, Blizzard could match the offer and I would have to choose Blizzard in that case.
plush yew
(I moved the question ot Career Advice)
autumn swan
@plush yew always talk to a lawyer first
plush yew
Fascinating
The Side Project program allows you during your spare time to make games?
For yourself?
Instead of Blizzard?
autumn swan
Yes
plush yew
That's awesome.
autumn swan
To get approved I have to submit, and not be stupid😎
Stay away from Blizzard IPs and avoid direct competition
plush yew
Sure
autumn swan
For example I could not make a diablo clone, or reference Blizzard characters

@native pawn there are a number of online animation courses for learning the basics of animation.
native pawn
thanks
autumn swan
Animation Mentor and others are good, but unsure of the cost.
granite swift
I can recommend mixamo if you're just slapping a project together in your sparetime and don't want to learn every profession that goes into making a game
Really easy to stretch yourself thin
native pawn
ok
autumn swan
I agree, Mixamo is useful in that case
granite swift
And getting good at animation is incredibly time consuming
Not to mention modelling

i am making a 3d platformer and wanted a good climbing animation

The difficult is going to be handling the blends to make sure they don’t look terrible

Of course! Good luck

Is there a good piece of documentation or article explaining how assets are loaded and cooked and how they’re controlled at runtime?

hi is this about UT4?
plush yew
aha ok
ive short tested UT4 but it was like a stripped UT4 and the only good thing was the pulsegun funny enough
no offence btw but am just being honest
the teamgames in UT4 were really like i was tripping on weed very weird
smoky stream
i doubt that offends anyone here
i dont think anyone here has ever written a line of code for that game
plush yew
okay
smoky stream
theres like 10 epic employees here max
and they all work on either the engine or fortnite
plush yew
ah ok
well its just that i exspected more an UT99 on the UT4 engine simply said
thats also why i emailed epic saying they should look into open source way but its like nothing changed the way i see it
it had a quake style gameplay somehow
maby just maby they should give UT4 fully to the community UT and let them devolop it the way they want more freestyle
technically seen at this moment UT3 seems to be the max
the maps making more slick and smoother isnt that bad though but i feel missing alot
smoky stream
if you made pull requests to the codebase im sure the one dev they left working on it would be happy to accept it
plush yew
and where is the codebase?
plush yew
okay yes i think i have account allready
however its not really my intention to interfere with UT4 making but
manic pawn
don't bother, ut4 is dead anyway
smoky stream
theres no one to interfere with anyway lol
you'd be like the one person working on it
plush yew
i noticed alot of UT and UT99 peeps wanted more UT99 look in everything also in weapons ,maps everything
oh haha lol
smoky stream
yeah just put in a pull request and as long as it compiles it would probably be accepted
plush yew
lol nevermind
i guess it has to end somewhere after 20yrs
its not that i find it funny but just the way u say it
smoky stream
it seems nothing except CoD battlefield and fifa lasts forever
plush yew
but what if i got a bright idea all suddenly?
plush yew
C++ that are big pills of books ill be 99yrs when i could use it lol
ok yes
maby its best i just wait
nothing is lost the old UTversions still rock
i was just thinking this way like, they import the UT99goty to the UT4 engine with all weapons,gametypes,maps etc only use the new engine and ued to make all better looking, just simple said
i think they made it to difficult for themselfs
they were thinking like we must create new gametypes, weapons,maps,bots etc
while they just could import like bot archon and ares and give them better visual textures etc
tranquil sphinx
sorry to interrupt, has anyone here ever come across any display port/monitor issues with unreal?
plush yew
no but ask away
tranquil sphinx
i've had a problem for the past week where loading unreal causes a monitor to lose signal and return but each time i move the cursor over unreal, the monitor loses signal again and returns
it only happens with unreal
i've just run a time spy extreme test to see if it would be a psu or gpu issue and it passed fine
changed cables, same problem, cleared drivers and reinstalled
same again
I'm kind of lost at this point
plush yew
give me few minuts to think and look
tranquil sphinx
nothing appears in event viewer and windows doesn't appear to have any logs, monitor is fine with everything else
plush yew
did u use a hdmi switch?
plush yew
oh god, UT4 talk for real? 😮
Epic hasn't touched UT4 since 2016
And we don't know if they will finish its development
They already killed Paragon
it could also be a setting in windows
have u set it to use multu display?
multi display
tranquil sphinx
it is using multi display
plush yew
have faith Hermit am sure Epic/Midway will find a way
i doubt Epic is going to work on UE5 anytime soon.
it is okay
have u also installed latest netframework and all that is needed for ut4?
Personally, i would much prefer the hardware to improve just so those consoles and PC can run UE4 better
tranquil sphinx
as far as i know, it was working fine until a week or so ago, it's been very intermittent since it started
plush yew
What netframework?
well have u tried reinstall of the UED4?
UT4 works fine right now, or... oky
Are you talking about reinstalling the Unreal Tournament 4 - Editor?
yeah
I have it installed. But I don't use it.
btw do the display port use converters or anything that could cause problems? Cobby?
like a hdmi to vha or to dvi
or hdmi to dvi converter
or is all straight connected
tranquil sphinx
it's direct cable from card to monitor
i'm just trying to find which dotnet i have installed
plush yew
okay and are u using double gcards? like crossfire maby?
tranquil sphinx
single card
plush yew
okay
tranquil sphinx
it's very odd
plush yew
yes it is
tranquil sphinx
if it wasn't just unreal i would suspect cable but i've tried 3 cables which would make me think it was gpu or psu but i can run games like 2016 Doom at full settings with around 200fps in places
plush yew
what kind of cables?
tranquil sphinx
which arguably be more intensive than just the content browser
the cables are 1.2
displayport
tranquil sphinx
i believe 1.4 is the latest standard yeah but 1.2 is the minimum for 2560x1440
which i've had running for several months without issue
until now
plush yew
well its wurth to try the 1.4 sinds its a signal problem,
and the fittings are hdmi or?
i can be shorter in answer, i would just make sure all is the newest like cable,fitting and maby use a 2-fitted switch just to try
tranquil sphinx
the monitor does have hdmi but i think hdmi 2.0 is the minimum for 2560x1440 which i'm not sure the monitor supports
yeah
i have another cable on the way from amazon
just to be absolutely certain
plush yew
aha okay, for now i think that is the problem somehow
tranquil sphinx
i've been monitoring the computer this evening checking things like temps, power usage etc to see if there was anything that could give me a hint
i even considered updating the firmware for that monitor
plush yew
and u cant run ued4 on lower resolutions?
tranquil sphinx
same issue regardless of resolution
plush yew
ok
tranquil sphinx
the strange thing is, the other monitor which it has no issues with, is a 4k panel
plush yew
is the other panel a FHD or HD ready?
tranquil sphinx
one panel is UHD and the other is QHD
tranquil sphinx
possibly
i'll post an update in here tomorrow and let you know if the cable changes anything, for now i'll reinstall unreal and the launcher and see if it helps
plush yew
but i would for sure do the fitting and cables
coral escarp
I am new at unreal, can give me general advice?

not even joking
you learn the best by doing

@coral escarp
coral escarp
I have experience in unreal but little, equally thank you
grim sinew
...think that's a little too far back
plush yew
well i can only say what i think, but u can also try UT2004Demo
though the full version needs a key to activate
but instead of the steam version i would rather buy a retail version which i find better
What's wrong with UE4? lolll
btw the UT3 needs a key too so
There is no point in trying the old Editors when you got access to UE4
smoky stream
if you want to dev these days it seems its either UE4 or unity
or go mad and use SDL2
plush yew
I think UT3 Ed doesn't even have a Content Browser
Was such a pain in the ass
jeff holt of BN clan knows alot of UED in general
hes good mappers also
from the UK
my guess is he still plays around with UEDITORS
i never used ued if i did it allways crashed so
The thing is before Unreal Ed had Unreal Script and now it's C++ & Blueprint.
And you have all those new tools now. It's a completely different engine experience.
So you should stick with UE4
ANd there are tons of info and tutorials on UE4 now
10 years ago, there was nothing for UE3
well C++ is a special thing on its own, and blueprint sounds like a addon for ued i have no clue what it is but its sounds difficult
Blueprint is integral to UE4
It complements the C++ workflow
aha ok for UT3 stuff into UT4 ed
yes i think i understand what u meen
A lot of people in this channel have extensive experience with UE4 that has been available for several years already now
i only know u need a bad ass pc or server to use UED3 and 4
cursive dirge
not sure if serious
plush yew
lol
smoky stream
yeah i can run it on my potato mac just fine really
cursive dirge
there's zero reason to use UDK today for any new project
plush yew
I disagree
cursive dirge
Epic doesn't even distribute UDK anymore
you'd need to find it from some shady online sources
plush yew
You can still download UDK 2015
cursive dirge
and no support, barely people who can help you with that
