any good tutorials for unreal ui designs ?
snow crown
nah, I've optimized quite a few unreal engine games so far
90% of the time poor performance is blueprint code
plush yew
How much would it cost for you to come in and fix our game?
snow crown
looking at your gamethread stats will tell you which blueprints and probably which function is taking the most time
lol, I'm currently working two projects right now
so, sorry, not looking for more
snow crown
on occasion, when I'm around
snow crown
the profiler show a lot of false leads
west quarry
how can I change gravitation pool in unreal ?
snow crown
you have to know how to read it
because, yeah, task graph threads are taking 5-10 seconds of not doing anything
but it's a task graph
that's super normal for a task graph
snow crown
Game thread is where your Ticks() and other game code live
Render Thread will tell you if you are doing something remarkably wrong
another tip for analyzing where performance is going wrong is to do 'stat unit' in the console
that will give you a general direction
grim ore
@plush yew so simply checking to see if you aren't jumping and to jump? Is this if the spacebar is down or all the time?
snow crown
if game is high, you might want to do 'stat uobjects'
if render is high, 'stat textures' or others might be your ticket
it might not be stat textures, one sec lemme look up the render thread stat command
stat rhi
that was the command
plush yew
Iron will ask questions when he needs to, but hes currently stopped by the timer
aaaah well
okay
snow crown
play around with them
there are many more
they will help you identify where the problem lies
without jumping into the profiler
usually the profiler is the last tool i use to find slow code
grim ore
@plush yew well spacebar is a one and done so when you land release is called and the while loop stops because you told it to.
You would need something that checks or calls it continuously like a tick or a axis event instead of an action event.
There should also be an on landed event that might be useful as an alternative
light thunder
Why am I getting three options spawned in this combo box when my print strings (on the event that literally adds the item into the combo box, is only showing two things added...why the duplicate option?

Any way to apply a post-process globally, not using a post-process volume? I have a huge landscape and want the volume to cover all of it. seems kind of counter-intuitive to use a volume with a size of 50,000x50,000,x5000
gusty bobcat
when i use my brush and hold down and move it it goes super fast and its hard to control.. how do i stop this or lower the sensitivity?
supple totem
@vast moon check infinite in the volume details
vast moon
@supple totem Thanks!

does anyone know why my levelscript begin play is never getting hit?
light thunder
@ivory linden Go to the level load node and is there a IsLoad or IsLoadSuccessful Boolean?
ivory linden
Wrong George
crisp fable
heh
ill check
there isnt blake
im not sure what you mean by level load node though
its not hitting that first breakpoint even
west quarry
do I understand it correctly there is now why to actually simulate gravity on a sphere without lots of hacking into physx engine ?
light thunder
@crisp fable I mean that Begin Play won't fire if you don't load the level, so find out why you aren't loading the level

elfin gull
man i get so excited and happy to work on my project but im completely discouraged by just not knowing how to make what i want to make
it's like wanting to draw a three and knowing in my head exactly what a three looks like and how to move my arm to make it happen
but i don't know how to hold a pencil
and i can't work out if it's not knowing how to hold a pencil or not knowing how to use my muscles
because i just dont understand how much i dont know
it's the worst
pulsar token
Best advice, start small and keep building on it. It is okay to not know what to do or how things work.

I'm struggling to record my matinee cutscene. Clicking record pulls out an unrecognised tab error, clicking movie pulls out the movie render... but it doesn't seem to record... anything
I just get this screen

elfin gull
it would just be super helpful to have someone who knows what they're doing to talk to and be like 'oh you dont know how to hold a pencil' so i can fix what i'm failing to identify as a problem
solar quarry
@grand knot The soldiers move. They stay in one spot but they move. Since I'm doing a matinee cutscene, I can make them move from one end to the other using matinee movement
now, can someone tell me how to record the cutscene?
Everything is set up, I just need to playblast it.
sudden creek
@grand knot And why would it cost anything?
solar quarry
How do I make the game run the cutscene as soon as the level starts?
grand knot
time is money
carmine wind
guys does someone know how can i get a switch param from a material in bp so by pressing a button i can change it to true or false
sudden creek
@grand knot Then make a time machine, Doc
abstract relic
@carmine wind Make a material collection. Then simply ref the mat in your bp. From there, you can use Set Scalar Parameter Value node for example
grand knot
@solar quarry reference the camera in the level blueprint drag off it and select play cine
@sudden creek ... good one'
carmine wind
but i want it to change it to true or false
abstract relic
Then use a Boolean
silver crown
You want to change the static switch?
carmine wind
yup
abstract relic
Lerp will be your best bet
silver crown
Or the if node
solar quarry
WHAT IS THIS?
it's 6am
why won't it just record the cutscene
why is it that when I click create movie, it just shows this
I've been at this all night
solar quarry
right, so I did a bit of tinkering and now I know that when I try to record the cutscene, it focuses the view under the map... eh?
wet berry
Anyone know if there's a way to reduce the hitching when a level is unloaded?
solar quarry
anyone know how to get the record function to record from the camera I want?
Ok now I know why it keeps being weird. It's recording from my skylight instance
my skylight is set as the capture focus... eh?
ok maybe not
the scene is just capturing near there
It keeps defaulting to the same location, how am I supposed to record this cutscene?
I am livid
I fixed the problem
and it was stupidly easy

It's an old question, but I still don't get it. I can do both, BPs and C++. And I'm quite comfortable with both, but I totally don't understand why the general consensus is that "it's better to do 90% of the code in c++". And I don't understand why. What am I missing? To me it seems quite the opposite. Like the only things where I see a reason to use C++ is for organization purposes and stuff that just can't be done in BPs. Everything is so much faster and easier with blueprints, and time is a huge factor, right? I mean there was an argument that BPs are slower, but now you can convert them to c++ and the difference is negligible. So... Why?
I just wanna use BPs without feeling stupid or guilty...
weary basalt
Then use BP. Dont listen to people that say those types of things. Make the decision for yourself based on your needs and your capabilities.
hard minnow
Yeah sure, but I was thinking like maybe I'm missing some crucial point
weary basalt
There are many reasons why you might use C++ over BP, but BP has its pros as well.
Some people feel more comfortable and confident in C++, others in BP.
BP obviously doesnt have the same reach and capabilities as C++ and thats one of its cons, but its certainly faster to iterate on.
Choose the right tool for the job.
If your designing/writing a complex time sensitive multiplayer experience then C++ is going to be the better option.
If your doing simple gameplay elements, then BP maybe a faster more time effective solution to use.
hard minnow
Yeah, that's why I'm still using C++. It's just that I feel comfortable keeping the most of my logic in BPs.
So there is nothing wrong with that? And it's a VIABLE thing in the industry?
weary basalt
Sure.
weary basalt
Typically though when you go to profile and optimise your game, you have more flexibility with your optimisation strategies in C++. If you have heavy logic in BP, your better off moving it over to C++ to get those benefits.
A healthy mix of both C++ and BP is not uncommon.
There are games completely written in BP. There are games completely written in C++.
Weigh up the pros and cons of both in the context of what your writing and your other requirements and make the choice thats obvious to you.
hard minnow
Thank you for such a detailed answer. You made me feel so much better :' )
grand knot
I have friends that have worked in C++ there entire lives and they always tell me running blueprints is practically the same thing and to just stick to what works
frank matrix
Hey guys, I wanted to ask why most UE4 games won't register my slavic layout of number keys above qwertz. Most games in UE4 don't support it. In fact noone except Deep Rock Galactic which added support just now few months back. This started happening with games running on UE4
frank escarp
the healthy way is to mix C++ and blueprints. Epic themselves do that
you use C++ for all the "core" architecture and basic logic
and Blueprints for things like enemy specific logic, or some basic event driven stuff
Robo recall is 90% blueprints and runs in VR
Fortnite itself also has blueprints for days

So how could an empty array run on a For Loop?
whole quarry
ForLoop doesnt use an array though?
light thunder
Because I'm printing the first index and breaking on the print string and it is negative 1,so its empty
static viper
an empty array run for loop will execute complete right away
light thunder
Um, that seems odd
static viper
how
if tthere is no legos in the box then you cannot analyse lego
so box is completed empty
no legos found
light thunder
For each element of the array, but it is running on an element that doesn't exist
light thunder
It is,that is the problem
light thunder
static viper
you are adding something before hand
light thunder
static viper
like... under that large white text box
what is under white box
is that a struct array?
static viper
you know that a struct array cannot be invalid?
you can add empty
so regardless of what you add
it has an index after that
so that addunique node is the issue
and its prolly all empties
zeros, empty strings, 0 length contents
light thunder
So other than a book branch to check if the array is empty or a negative index, I'd there a better way to ensure the loop behaves as expected?
static viper
create a serialize bool
so that you can only add if the function returns a Serialize true
with a branch
serialize as default true
done
slap it right on the function
as input
light thunder
I'll have to look up serialize, never worked with it before...thank you for pointing me in the right direction
static viper
i just called the bool thaat way
XD
you can also call it
kekse, owlsbool, mynewbool1, Awesome, aaaaa1, aaaaa2
XD
light thunder
So on that add unique node, make a branch if the index not equal to negative 1, then execute loop?
static viper
no
light thunder
I'm on mobile or I'd show
static viper
you created a custom function there, on that you slap a new bool.
if that bool is true you it will do an addunique
if false it just loops
so a branch before the addunique
false loops
true goes to unique which leads into loop
10 seconds work!
light thunder
What drives that bool?
static viper
you are working with array structs here... you are supposed to understand what i am saying...
light thunder
When is it pos or neg?
light thunder
I mean that custom function ,that's a branch...what determines the boolean value driving the branch
grand knot
okay finished with @chrome summit you're welcome

why are u feeling so generous today
light thunder
@static viper Not trying to be dense here and I appreciate your help (I was on the move and on mobile phone, maybe I missed something) but you are talking about adding a bool and branch before the add unique struct to that array event - but what is that bool determined by, that's what I missed, when does it get set to true, false...do I just set it to true on the first loop through? I know how to fix it but I want to understand why this is happening (my knowledge is good for a nonprofessional but still fragmented)
static viper
it does set whereever the function is applied
why would you even have these 2 things in one line
addunique and then a loop for the same array
there lies the main issue
they should not touch if the loop gets errors

weird bug is weird, using uv1 for some shadermath, but the moment the mesh is in cascade it reverts that math to uv0
thats a new one
only this one mesh too
oh god, and the horrible max bug where --because two max apps opened at the same time-- it reverts all fricking settings.
novel spire
I drag a static mesh directly from content folder to the scene, and it becomes a StaticMeshActor. I drag an Empty Actor from "Modes" into the scene, then add a static mesh component to it, and it is still an Actor. What's the difference between these two ways of doing things? And what's the difference between StaticMeshComponent and StaticMeshComponent (Inherited)?
sudden agate
A StaticMeshActor is just a shortcut.
no performance difference or something like that
novel spire
Okay, is there any difference between a component and a component (inherited)?
sudden agate
no
it just means the component is part of the BaseActor
For example you have AActor -> AStaticMeshActor
AStaticMeshActor already has a UStaticMeshComponent. If you drag and drop a Static Mesh into the Scene, you create an Instance of AStaticMeshActor which inherits the component
novel spire
I see that makes sense. Thanks!

Is it normal for Unity users to talk crap about Unreals blueprint system?
Just wondering
plush yew
It probably is tbh
I got done visiting the main Unity server
And man oh man you guys really dont wanna be there
xd
But I mean
If you're incompatible with pure coding,
What other decision is there
I get that Unreal is slightly baby-ish in the aspect that its as simple as connecting two nodes together (thats probably just me, I view it as simple)
south ridge
Unity users talking crap about Unreal blueprint system is 67% normal
plush yew
But... Its a good alt for devs
Alright. Just double checking myself
I presume its that way vice versa, in the sense that Unreal devs talk crap about Unity
Im new to this kind of world so, s'cuse my questions

I dont think its common for UE users to crap on Unity.

It has its own set of cons sure, but its not like we sit here arguing over how shit it is.

True. Gotta keep that in my mind

I would only make fun of choosing unity over unreal for some types of large projects
plush yew
Besides, Unreal isnt all about BP's anyway
They do have behavior trees and material nodes and all
Like Unity has it's own uhm.. I think it was the animation blueprint
weary basalt
They are subsets of "blueprint"
weary basalt
"Blueprint" is a wrapper on C++ functionality.
plush yew
I generally call it "super duper simplified C++"
Unless.. if that was what you just said
weary basalt
Its just exposing common features to the Editor in a more designer friendly way.
Its not simplified C++, it is C++

The AttachToActor node in BP literally is a single line wrapper for the C++ implementation.

novel spire
I have an object that simulates physics. When it's dropped onto a table, the physics and collision work well. However, when I drop another similar but smaller object onto the table, the object goes half way into the table mesh, and keeps shaking.
If I set the table to simulate physics, the small object's physics and collision will work. But now my character can kick the table around.
I wonder what's the cause for the shaking, and if there's a better fix for the problem?
wet berry
How small are you talking here?
novel spire
It's a model of a USB drive
wet berry
What's the phsyics asset look like for the usb drive?
if you scale the USB drive to the other object, does it behave as you'd expect?
novel spire
Hmm I haven't tried scaling it. I'll try that later.
But what is a physics asset? I know it's a static mesh that uses "complex and simple" collision.
wet berry
A physics asset is how you tell a skeletal mesh to deform when it simulates physics. I'd take a look at the collision of the object that isn't working correctly
You aren't using a skeletal mesh so the physics asst doesn't matter/exist
I'm guessing you need to regenerate collision on the USB static mesh
Physics can get weird at certain scales, but something the size of a USB should be fine...I'd still try scaling it up and see how it behaves
novel spire
I see, thanks for the advice! I'll launch the editor later and try regenerating and scaling.
wet berry
And generally you want to avoid complex collision (as an optimization), but for physics it's doubly importatn so make sure all of your meshes you expect to interact with the physics system have well-build simple collision primitives
you can generate pretty solid ones for convex shapes automatically in editor. You can also hand place them (either in editor or in your modelling software using UCX tags)
novel spire
Okay let me see!
plush yew
hey, I have question about physics and Paper2D
I have character with CapsuleCollision component as root component of the BP
And I have wnother CapsuleCollision component in it
Both capsules have same settings for pysics and collision
but only one capsule counted as character "volume". Second one works only for movable actors, like this green platform on the left.
regal mulch
The CMC will only use the Root one
Actually, is that little guy using the CMC?
(CharacterMovementComponent)
plush yew
yes
it has CMC
So, what if I have non-static collision component, like when character crawls collision component should become smaller
yeah, I know That I can change height/radius of this capsule
but what if collision volume is complex?
for example: character has big gun that will add extra collision volume in the front
regal mulch
That's not important for the CMC
The CMC only reacts to the root one for calculations.
At least afaik
If you don't want the other capsule to push the platform, you need to change the response channels to overlap instead of block
plush yew
so, I want to have complex collision volume, that can be composed from several components
peak vigil
I can't open a uasset file I placed in my content folder, here's the file in question
wary wave
IIRC, characters can only have one collision primitive
this would mean having a second collision primitive for overlaps etc just won't do anything
cloud cobalt
This is an interesting topic - I was surprised to find out that MoveComponent() does not check attached components for collision, relying on auto weld instead
cloud cobalt
I actually needed that so I've written an overriden version that does
Which is no simple feat
wary wave
I looked into it at the time and decided it was a lot of hassle
so for my purposes I just separated my second collision primitive into another actor and had done with it
not ideal for every use case
cloud cobalt
I implemented a simplified version of MoveComponentImpl for my root component class that does something okay-ish for attached components, it's 100 lines of primitivecomp copypasta
I played quite a lot with attachments before and auto-weld is not what I want for anything dynamic
wary wave
I was only using it to diddle first person weapon arms to avoid obstacles (so putting the collision primitive on the weapon wasn't a problem)
cloud cobalt
Yup

How to set velocity for 2d actor? I wanna implement walljump, but cant "kick" character from the wall. "Add impulse" seems work, but when I press move key towards wall it barely jump from wal and mostly jumps straight up.
So I tried to set velocity to 0 before adding impulse - same effect
I wanna to prevent jumping up with only one wall, so character won't able to reach same wall on same/greater height
wary wave
I would expect impulse to work as intended, so I suspect there may be a problem with your actual implementation
(you may want to take this to #blueprint)
peak vigil
I can't load some uasset files into my project, any suggestion?
sudden agate
uassets are not meant to be imported
peak vigil
I've put'em into my content folder, but they didnt show up
sudden agate
You can try copy the Uassets in the Content folder, but only works with the same Unreal Version
cloud cobalt
Or an older one
sudden agate
it will also destroy any dependencies
peak vigil
how do I know what Unreal version should I use?
peak vigil
from Street Fighter 5

Lol, can't help then

OMG
cloud cobalt
Don't steal assets from other games
They're not going to be using a public UE build either anyway, and they won't include editor data
If they're any big they probably protected the assets in some way to prevent exactly that
peak vigil
Which means they're cooked right?
cloud cobalt
They are cooked since it's a game
languid shard
which means unless they release a modkit you wont be able to do much with it
cloud cobalt
More to the point, do not use assets from another game
peak vigil
Why is it?
cloud cobalt
You won't be allow to legally release your work if you use content you don't own

Even if it looks like shit or is just flat planes of solid color - it's miles better than anything taken from another game
And it's something you'll have every right to
My 2 cents ๐
peak vigil
I see now, but I also can't open some mod files created by the fans of the game, are those files cooked as well?
regal mulch
Most likely?
cloud cobalt
Everything from the game is cooked, by design
Literally only way you can release your game
peak vigil
Even the mods for the game?
cloud cobalt
Uncooked assets can't be played without the editor
Mods are cooked too
Anything that plays without the full UE4 editor is cooked
Just as an example, shaders (materials) have to be specifically compiled for specific versions of DirectX, OpenGL or Vulkan
Compiling A) takes like half an hour and B) requires the editor

Regarding casting every time for something in a function vs setting one reference at begin play, what are the pros and cons?
For example an owned character reference in the AI Controller
Sure you can get controlled pawn and cast to the character class every single time you want to use it (as shootergame does), but is there a reason youโd do this when itโs much slower to write and more inconvenient to read through than a nice single blue reference node?
Is it a rule of thumb or good practice to set a reference when you see yourself casting for the same thing say 10+ times in different parts of a class?
paper kernel
obviously using reference is more efficient(in very small scale), but it really comes down to how persistent the referred object is
sudden agate
I use Components. Pawns are just a Container of Components. Nothing more.
steady owl
@paper kernel in very small scale as in only make a few references per object?
And the pawn is pretty much always there
So it would make sense for the controller to have a ref
Just wondering why ShooterGame rarely does make references but does a lot of repeated casting
paper kernel
no idea, memory saving maybe?
steady owl
Ok thanks! I wonder if a standard character ref would eat up memory or if itโs just an extreme optimization
Iโll have to learn to profile that
Would a cast actually be slower than just plugging in a ref?
paper kernel
by a few cpu instructions I would assume
digital anchor
it wouldnt save memory, theres no performance improvements, nothing will be faster or slower, do what makes your code looks cleaner
steady owl
Ok thank you!
digital anchor
i personally will always cast, i can see the source of the reference
and i have no risk of references changing
steady owl
Well in this case the source is always get owned pawn
paper kernel
and I would assume mass editing class names is easier when it's casted
steady owl
So itโs the same exact cast x 100
digital anchor
yeah, if it looks better go for it
steady owl
I had read to avoid cross references (like the controller having a pawn reference and the pawn having a controller reference) but Iโm trying to avoid that
Is it the worst thing in the world if it is there on a class or two?
For example the character has to send a UI notification to the controller
But the controller has a character reference for something else
Or maybe I should just always cast for one of the references
dim plover
Just curious, how do you guys back up your projects? I've just been copying pasting the project directory to either some cloud storage or other storage devices.
digital anchor
with a #source-control software
dim plover
Sometimes I delete the Binaries and Intermediates to save space. I don't really use a typical source control service because the projects are just so large.
I didn't investigate, but can you source control the ussaset stuff?
digital anchor
well, being large is one of the reasons to use it
as they will only upload what changed
a few can, SVN, Plastic, Perforce, works with binary files
Perforce being the standard choice, Plastic have some nice features but is paid, and SVN is the easiest of them all
dim plover
Alright, thank you. I will check out Perforce.
steady owl
Does a reference have a different size in memory depending on how big the class is? For example a standard character reference vs a specific character child class with lots of added functionality
steady owl
Ohhh wow
Thank you
And here was me constantly making references to the base character class thinking I was more efficient...
manic pawn
but if you're working in blueprints, referencing specific child classes will require loading them and all parents when opening the blueprint
steady owl
@manic pawn is this purely slower only for working in the editor?
Or does it also impact runtime performance
manic pawn
this is mainly about editor performance
for example, if you're referencing your custom player controller bp, which references your custom hud bp, which references a ton of widgets, which reference textures, ..., all that garbage is loaded when opening this one bp
steady owl
Ok got it
So in my case unless I really need to access something specific
I should stick to the character class
And not the specific child
manic pawn
yes, there is no point casting to the child if you're not going to access anything specific on it
steady owl
Well in say 50 uses there might be 5-10 cases where Iโd need something specific
But in those cases I can just cast
dim plover
I heard a while back that casting in BPs also causes those references to be loaded.
dim plover
Well, for BPs interfaces.
steady owl
I just mainly care about runtime
dim plover
In the case I heard about, it was impacting their runtime performance greatly.
Let me find the thread.
steady owl
Thank you!
manic pawn
if you'll need the specific reference anyway, just cast as few times as possible at runtime instead
manic pawn
yeah, this is the same thing
at runtime the issue is usually less relevant since you'll need that content anyway
wary wave
well, this is the thing - he didn't need that content
because his player was referencing things like particular bosses, they were always being loaded in every level
manic pawn
oh well that's pretty stupid
wary wave
it's a pretty common mistake also
sudden agate
This is why Components are a good way to encapsulate things
steady owl
As in don't get a reference the character has to an enemy from a class outside the character
light thunder
It just means have DIRECT blueprint communication whenever possible
sudden agate
Ideally, you wouldn't store any reference to other objects at all.
I try to avoid them as much as possible. I only use Base Classes (AActor) and Interfaces alot.
@light thunder no, it means the opposite.
dim plover
Do you use UInterfaces in cpp or in BP? Because I've been pretty hesitant to use UInterfaces in cpp.
steady owl
Well if casting does the same load in memory thing then I'd be inclined to use references where I need to
sudden agate
I prototype in BP and then transfer it to Cpp
dim plover
I don't think using references would help you in this case. I think it would cause the same issue as casting.
The UInterfaces in cpp are pretty weird.
steady owl
I just need to call things from the AI controller to the OwnedCharacter and I'm not sure of a better way to do it
I also need to store enemy Character references
BestEnemy and LastSeenEnemy
unreal spoke
Is there an equivalent to "OnExit" or something like that for a blueprint on an actor? Basically I want something to happen when the game is quitting.
sudden agate
EndPlay
steady owl
So would it be potentially bad for the AI to use his OwnedCharacter reference to get it's EquippedWeapon reference in order to check if it should reload?
I can of course do it the opposite way and have the weapon check every time it is fired if the owning controller is AI and if it is reload if under a certain number
dim plover
I think it's okay in your case, since all those objects would be loaded anyway.
steady owl
Ohh I see so it's only bad if it's not something that is in the scene or will always be loaded?
EquippedWeapon will always be there
dim plover
From what I understand, as long as you don't cast to 100 different types, some of which aren't ever loaded during normal gameplay, you're fine.
Or objects that reference a lot of objects who also don't usually exist.
steady owl
Ok cool- my weapon would only reference the owner which always exists
normal jolt
Heya fellas. Anyone know what can I do if UE4 doesn't want to use my dedicated videocard? It uses it... but very occasionally. I even forced it to use through Nvidia panel, but to no avail
unreal spoke
@sudden agate Thanks
sudden agate
@steady owl there are people out there who keep references to all weapons possible in the game in the character that uses them.
Or they keep references to all objects the player can interact with. (which is caused by casting to every specific type).
The point is to not do exactly this. Abstract it away with either components, interfaces or a common base class.
steady owl
Well in my case I have one EquippedWeapon ref that is from the base weapon class that all weapons are derived from
Would it be a big deal to have that stored as a reference?
sudden agate
perfectly fine
steady owl
ShooterGame does something very similar
Ok great
thank you
I'll do my best to not go crazy like those examples you mentioned
I won't hold references to loads of unused classes and will try to keep them to the highest level possible

Hii.. How to update a CSV file continuously during runtime
cloud cobalt
Gonna need more detail on what you're doing
Updating files continuously is not common
sudden agate
DataTables cannot be changed, if that's what you want to do
steady owl
Is it possible to turn off UE4 creating those backup .uasset files in the saved folder?
austere hinge
@cloud cobalt currently Iam working on a car parking project.. Where the user will update the parking slots outside unreal and it should get the data from outside and make a data table and should park on the user specified places
Iam using a editor script function read from csv file I guess, it is working when I play in editor.. But it's not working when I build into exe file
sudden agate
@steady owl auto save in the Project Settings or Editor Preferences
steady owl
I have that turned off
But the backup files are still being populated
I'll look again, maybe missed something!

How is this documentation for 4.22? https://docs.unrealengine.com/en-us/Engine/Rendering/Materials/HowTo/RadialMotionBlur
grim ore
because you are from the future and found something you should not have.... I would run.
cloud cobalt
Though it seems convoluted
cloud cobalt
Okay, so the radial motion blur is a material set to a dummy actor on top of the real one to process the stuff behind it
static viper
What???
lament star
probably not soon since they wanted to integrate the DXR framework
static viper
Dafaq did you just say xd
cloud cobalt
TL;DR of the linked doc page
static viper
A dummy on an actor for just motion blur xd
cloud cobalt
I hope it can be fast enough for gameplay
It's been a desired feature for a long time
fair violet
Yeah had so much trouble with motion blur on spinning things before
Especially with light bleeding through
cloud cobalt
Since it's a material, chances are it's also mutable into a direct pass
I kind of hate the dummy approach
wary wave
I was under the impression a form of radial blur has been in for a while
grim ore
ooh... oooh... they are doing it... all the copyright notices are getting updated in the source... the big changes we were waiting for are finally done! whoooo 2019!

Hey, I am trying to put VR teleportation in a level and it will not work properly and I have no idea why it won't work. Would any of you know what the problem would be?
wary wave
we're not psychic; we have no idea what you're doing
define "put VR teleportation in a level"
grim ore
set actor location on the player? profit?
stark lava
I am trying to put teleportation inside a VR tour my tech class is doing and I tried to do the add new feature or content pack which allows me to add in the VR blueprints and everything but it messes up and doesn't show hand gripping nor teleportation
wary wave
what do you mean "add new feature or content pack"?
stark lava
While in unreal editor there is a add new button near import and save all button in the content browser
wary wave
gotcha, never even knew that was there xD
I would not use this feature, seems like a bad idea in any case because it won't set the config etc up properly
create a new VR project from the launcher, then migrate your content into that VR project
stark lava
Yeah, I tried that but went a long list of failed to migrate message log
wary wave
then you might want to look at why it failed to migrate
grim ore
when you add the VR feature pack, did you swap over the game mode and load up the sample map?
wary wave
@grim ore - chances are all the config settings, renderer settings, the works, will be all wrong if you add the VR stuff that way
stark lava
I have no idea. I'll look into it
wary wave
you may find the 'failed to migrate' warnings are largely meaningless if you actually test it

Yeah

i agree, its ridiculous
the legistlation itself is written so badly its painful to read

no one should support this
it can only be fixed with large developers working against it aswell

I agree, but in the event it sticks, a plan has to be made moving forward to comply
it is ridiculous though, completely
