Callin me Mr. Obvious yet youre the one with the crap advice
static viper
you hate this yes. But it doesnt change a bit.
are you not making backups
and we already figured out your engine is fine.
so rolling a backup would be great
tardy sapphire
It gets back to normal when I disable the plugins
And re-enabled them, buggy again
Interesting indeed
tardy sapphire
ฤฑ DฤฐD
static viper
and send it through vs
tardy sapphire
I did*
tardy sapphire
I deleted and re-copied them to the plugins folder
Will see now
Still buggy
-_-
dim arch
think it works if you can find the offending plug
dim arch
then you need to make it compatible with the engine
possible the plugin broke, try deleting everything except \content \plugins \source and the .uproject file in the project
(make a backup)

@polar hawk Hey, i still dont know what a pooling system is : ) google made no sense to me
dim arch
like aggregating ticks to reduce frame times?

To my question earlier. I was able to hide the plane in game. But I can't seem to make the collision detection only ignore the player. The only option it gives me is to ignore all pawns. Any thoughts?
proven hearth
Anyone know how to add an extra column to the World Outliner? Can't seem to find an option to add one, only to change the second column.

I just added a !
By the way
is there a channel to like collaborations and stuff?
calm widget
maybe #looking-for-talent
wraith acorn
Yeah I looked there but, I want a collab and not something that is really benefical in money
calm widget
Yeah, kinda figured. But i think that's the closest one, or you could just ask here i guess. Not sure tho, depends on what you want i guess
Does anyone know what a pooling system is? The suspense is killing me!
@wraith acorn What exactly are you looking to collab, if i may ask?
glacial pecan
I auto generated lods for all static meshes in my project, now how do I nuke them? ๐
calm widget
What?
wary wave
I believe the documentation is correct and you need to be launching standalone game
you won't be able to
you will need to launch standalone game for that

if i use unreal engine to combine multiple actors into one static mesh, it doesnt optimise identical uses of a texture. to summarise, if i merge actor A, B, and C, and each uses material 1, 2 and 3, then it will make 9 draw calls, and won't optimise it to 3 draw calls. is there any way to get unreal engine to be smarter about this when merging actors to an SM?
whats worse there is if i have one actor that uses one material and i merge 10 of them together into one SM, i get an SM t hat takes 10 draw calls to draw. surely theres a way to do better?
wary wave
@west bane - yeah, you'll probably have to. IIRC the command switches are only processed on application startup - so if the editor/engine is already running that's that (but starting a new process/instance from the editor will work)
odd steeple
Hello, I have a mesh and a point light in an actor blueprint. Is there a setting I can change so the mesh is invisible to the light in the blueprint? I'm putting the light inside the mesh and I want to make the light act as if the mesh isn't there at all. Never mind I found it, unchecked the cast shadow box in the mesh details window.
azure shore
ok why when I just duplicated a wall the lighting literally unbuilt in front of my face?
wary wave
because you invalidated the lightmaps
azure shore
but surely other areas that have already been built would be unaffected?
wary wave
the new object might affect the lightmaps on other objects, so the engine cannot assume they should be left as is
azure shore
ugh ok then
lighting has gotta be one of the most annoying things about mapmaking
why wont pressing p show the navigation area in my map?
azure shore
ok it turns out you need an actual pawn with pawn sensing in the map, I only had enemy spawners
but is there a way to manually create areas to walk in, a lot of the paths seem to thin
too
wary wave
you shouldn't need a pawn to generate navigation data
azure shore
yeah I didnt think so, but I dragged one in and that showed all the green for some reason
the navigation was already there I just couldnt visualise it with p
radiant haven
compact oyster
Topic?
wary wave
obviously, an AIController is not a pawn
also there's a player controller reference in there too
this makes no sense
compact oyster
Does anyone know if having nodes in the "preview" section of a Function Material Node Input affects the performances for the material or is it cut off when the shader is compiled if it's unused?
wary wave
it's cut off
compact oyster
Nice! Thanks
wary wave
you're targeting a player controller
also 'GetController(self)->GetAIController->' makes no sense
either you're already inside an AI Controller or a Pawn
presumably a pawn
polar viper
I don't think unreal likes my low poly models (just for testing before i officially start)

I'm currently working on a VR project, and I need to create some "sliders" for the player to interact with. I believe I can make them grabbable with the pick up actor that's built into the VR Unreal Template, but from there, I could use some assistance on getting the slider to "lock" to the axis that it's supposed to slide on, as well as getting the engine to detect when it's moved all the way over. Any ideas?
wary wave
you can literally lock components to axes in their settings
blissful willow
In blueprint settings?
blissful willow
@wary wave I found options to lock to X, Y, and Z position, but I believe those are world position
The sliders don't move along the world axes, they move at about a 45 degree angle, so they need freedom on the X and Y still
And even with the constraints on, I can still freely move it with my motion controllers...they just "snap" back to their start position once I let go
wary wave
you'll have to do it manually with math, then
blissful willow
I'm not quite sure I understand how you mean by that
wary wave
I mean you're going to have to define an arbitrary axis yourself and clamp the objects coordinates to said axis
there's no magic bullet or node
it's math time
blissful willow
I didn't figure there was, I'm still just a bit new to BPs and coding in general. I've seen clamp before...but in order to clamp the values, I need to somehow tell UE4 the object's local axes, right?
Or is it a bit more complex than that?
Maybe getactorlocalvector?
I guess the specific ones say "get actor (up, right, and forward) vector"
wary wave
I suspect you may be out of your depth, but;
https://answers.unity.com/questions/1229112/clamp-a-vector3-position-to-an-arbitrary-line-segm.html
blissful willow
Oh, I very much am out of my depth. I just don't have a choice at the moment. ๐
I appreciate the help very much so though
placid arrow
im trying to put a widget into an actor, basically a umg slider within a 3d object. functionally it works, but its all washed out like its opaque. nothing i can see anywhere is defining it as opaque
can anyone please tell me what makes the diamond dark like that?
last time i had this problem, i had to project it to screen space rather than world space to fix it, in this case i cant do that

(is it normal behavior that blackbody node outputs a different color than the color of the light when you input the same temperature? I thought those were based on the same calculation EDIT: Nevermind, it was an user problem)

Compiling source ๐
serene birch
at that point I'd be sad if we don't get to preview 10 for the record!
vale silo
it looks like there is 1 unresolved bug in the issue tracker for 4.23.. So we might just get 4.23p9 before the release ๐
earnest lily
For a completely procedurally generated game is unreal engine something practical to work with or would i be better off working with direct3d directly?
wary wave
depends on what you mean by "completely"
but there are plenty of games using procedural generation that use UE4
earnest lily
Rimworld style situation where the world is pre-generated and you can have multiple saves on a world
/ Dwarf Fortress
actually yeah dwarf fortress is a better example
wary wave
sure you can use UE4, why wouldn't you be able to, and why would working with D3D directly give any advantages?
serene birch
you can have a completely dynamic works in UE4
the dwarf fortress scale is more what will cause you difficulties than the dynamicity
earnest lily
i more ask since ive got a bit of c++ / direct 2d experience and other low level stuff but not worked with an engine before, ive had a poke around in and noticed the majority of the interface seems to be around building 3d enviorments directly which is why i ask about procedural stuff
wary wave
I wouldn't expect much of an interface if you're generating stuff procedurally, no? Anything there would be bespoke for your project
games like Deep Rock Galactic are heavily proceduralised
earnest lily
well yeah thats what I mean, it's hard to get a hold of whether what I can do "under the hood" is limited by using the engine without asking someone
grim ore
uhm... 4.23 did come out why has no one said anything lol
serene birch
the way I see it, the engine is perfectly capable of having fully runtime generated levels, provided you can live without :
- precomputed long distance terrain lods
- precomputed shadowmaps
and stuff like that
grim ore
it's like not even on the official website lol
earnest lily
As you'd expect for rando on discord this is still in the pipe dream phase but I've been very interested in making a voxelized mix of a rogue like and minecraft

that's so weird, did epic forget they released .23 https://docs.unrealengine.com/en-US/Support/Builds/ReleaseNotes/4_23/index.html lol
real hound
Having an Access None error when trying to get player controller and set show cursor in my game instance. Any ideas?
fleet rain
its weird mathewW its like something got messed up here
i just did the update from preview 8 to preview 8. I'm not sure if this was supposed to say preview 9 or if this was supposed to be the released version.
serene birch
the launcher wants to update to the release version here
doing the update right now, let's see what I have in the end
fleet rain
hmm. well i just ran the update and mine still says preview 8. relaunched and still says p8
glacial pecan
@grim ore I hope they didn't release it, because you can't build WMR projects with preview 8
vale silo
@real hound perhaps your player controller hasn't been spawn yet, when you are trying to access it ?
real hound
I acutally figured it out. Doing a Is Valid with a print string showed me the server was trying to access it aswell and that was throwing the error.
Its funny that gameinstance doesnt seem to have switch has authority
grim ore
@glacial pecan I dunno it looks released to me lol
dawn vessel
Damn. They must've released it O.o
fleet rain
well the version i have here is: 4.23.0-8386587
real hound
I do have a peculiar problem however. I am using Find Path to Location Synchronously, however it will not work unless I already have an instance of the player character spawned on the map. I spawn the characters on begin play through the player controller, and they will work fine so long as there was already a chracter placed on the map.
grim ore
welp I guess release notes gives me something to do for the next 3 hours at work ๐
oof... this... was not expected tho "Chaos functionality in Unreal Engine 4.23 must be enabled and compiled using a source build. See this guide for instructions on enabling Chaos."
I know it was like that during the previews but to have it be source only for a big feature like that is gonna be alot of people asking how to compile source lol
vestal drum
anybody know why the update is so huge ? 11+GB updating from Preview 8, my guess is it downloads android & ios crap even though i specified before in options that i don't need it
grim ore
it looks like you might be right on that one, I even had linux support auto added lol
might be best to just delete the preview and reinstall the final without options
vestal drum
yeah thought so, thanks for confirming
grim ore
I was wondering the same thing on my update but I have bandwith to spare so didn't care to confirm heh
vestal drum
yeah don't want to download 6+gb for something i will remove afterwards because of SSD space
someone messed up @ Epic on this one
grim ore
yep yep, thankfully removing works
fleet rain
i'm kinda surprised it'd get posted right after the holiday weekend
vestal drum
just wanted to confirm if you do a new install without any of the target platforms in options it's only 5.47 GB
fleet rain
good to know thanks
vestal drum
also got a substance plugin warning, i guess the launcher tries to install that plugin by default when you have it installed for an older version
dim plover
I've heard problems with people installing a new versions without deleting the previous previous versions.
So, in your case, it may be better to delete the preview anyway.
fleet rain
yeah i'm removing my preview 8 build cause updating seemed to be buggy
vestal drum
the problem is the latest update not respecting your install configuration from before and tries to download extra target platforms you did not have before
not a big deal for most but instead of a 1.5GB update you get 11+GB lol
grim ore
yep it's officially official https://www.unrealengine.com/en-US/blog/unreal-engine-4-23-released
vestal drum
that's a long read
grim ore
it's only like 1/5th of the actual release notes heh
vestal drum
yeah i just saw the scroll bar get tiny, it's mostly pictures
for full release notes
fleet rain
there's a lot going on in 4.23. i understand their urge to get it out, many of the updated systems aren't complete or perfect but they are good steps in the right direction. it has to be good enough or else they'll sit on 4.23 forever trying to get in every feature they wanted
cloud cobalt
Any idea why this does that ?
Basically, looks like you can't build arrays of event delegates.
vast fossil
hey guys quick question. Im trying to learn the multiplayer phase, I test my project with server side and client side windows and when I set the client to 30 fps, the server window also reduces to 30 fps. Doesnt the server have his own fps or tickrate ? What am I missing here ? The thing is I want to test how it will experience if a client has low fps. Who can put me in the right direction ? thanks
@cloud cobalt your custom event 0 needs to be plugged into the print string
grim ore
it sounds like you are testing with a listen server?
cloud cobalt
@vast fossil Nah it' sjust Blueprint doesn't support this
vast fossil
ah oke
cloud cobalt
Using a structure around the delegate type fixed it
vast fossil
@grim ore basically with PIE
grim ore
so you see 2 players then, that would be a listen server and with PIE that makes sense you are limiting the frame rate for the editor
you need to decide if you are using a listen server or dedicated server setup at this point and go from there
vast fossil
hmm, any good tutorials about this subject ?
grim ore
have you read the unnoficial ue4 networking compendium?
vast fossil
thank you
grim ore
the basic difference between a listen and dedicated is the listen is a server AND client
vast fossil
I probably need them seperate which seems more logical for my project
with the servers fixed tickrate
grim ore
when you think of a traditional networked game a dedicated server is more than likely what you are thinking of so yes you might want to look into that and start coding/testing with that (you can still do this thru the editor for testing). It's not the same result as a listen server
dim plover
I think the majority of non-AAA games have strayed away from dedicated servers.
vagrant yew
So, 4.23 was released. Who is doing Balls of Steel challenge? (Upgrading your only copy of the project to new version without backup)
Not me, that's for sure.
vast fossil
when I check "run dedicated server" that will be enough for testing right ?
grim ore
for testing yep, it should spawn a new dedicated server in the background in addition to your clients
vast fossil
alright thanks
vagrant yew
damn, u good
vast fossil
does 4.23 have a fixed timestep for the physics ?
calm sphinx
If you need deterministic results, there are immediate mode for Physx afaik.
I thought you were talking about physx
Chaos is possible, yes.
vast fossil
oke

What are you working on john? Oh I've started working with chaos
polar hawk
@calm widget aye then don't worry about it
placid leaf
does Chaos, when enabled, replace PhysX (for e.g. character movement, extent traces, etc.)?
grim ore
it should not, it should just be for destruction
vast fossil
how do I add a "playerstart" in my world outliner ? I cant find a blueprint called that name

radiant fable
does 4.23 still have to be launched with a dx12 flag to get rtx enabled?
serene birch
4.22 had and I haven't seen any mention that it would change
at best I think you can hope to have raytracing work with Vulkan ๐ RTX is a DX12 feature
grim ore
it does not
you can go into project settings -> Platforms -> Windows -> default RHI -> direct X 12 and restart
no need for flags for a few versions now
radiant fable
oh nice, thanks, looking into now
grim ore
yep once it's restarted you can hover over the project name in the top right and see which RHI it is using
radiant fable
useful, now i can go back to launching my projects from the epic launcher

Only if you need the space, uninstall the oldest version.

How practical is it to ignore the editor and just use unreal engine as an API in visual studio?

Hey guys, quick question. i have a C++ pointer of a class i made.. but when i assign it in BP and press compile it resets(aka doesnt take the value). what coulld be the reason
it goes to none
dim plover
Don't Hot Reload.
rose glen
i deleted all files, and regenerated the code
i was on ue4.22 , and upgraded to 4.23
removed the generated code and regenerated
still
mossy nymph
assign it in BP on instance or defaults?
next badger
HOLY F*...i've started to install ue 4.23 4 hours ago...and it was still installing...just stuck on 55% and was writing whopping 400mb/s whole time
mossy nymph
there is a little bit of a difference between the two
exotic lion
The 2?
rose glen
i created a custom c++ player controller > created a blue print from it > assign the value (fails)
exotic lion
You mean the launcher and the SC?
mossy nymph
i mean assigning a pointer on an instance of the actor on the level
or assigning a pointer on a class CDO
scarlet birch
Sometimes it hangs up when it has to compile shaders or something. It can take a while depending on your system.
mossy nymph
first works, second doesn't without the Instanced specifier
rose glen
@mossy nymph , im not sure im following here
mossy nymph
you can't instance objects in class defaults
unless
object's class has EditInlineNew specifier
and the UPROPERTY holding the object has Instanced specifier
earnest lily
@serene birch more asking if it Imposes any limitations
scarlet birch
@next badger That does seem excessive though. It only took a few minutes to download and install for me.
next badger
hope it was not writing those GBs for real tho...
rose glen
@mossy nymph so i should instance it on BeginPlay ?
mossy nymph
that would work, but it would not be editable from BP editor
next badger
that's 6Tb of data
mossy nymph
you can alternatively add those 2 specifiers and instance it on the CDO
rain dome
so, do projects created on older version of ue4 work on the latest version?

And you should avoid using Hot Reload. Unfortunately, it is mega shit.

Ambershee, you see this?
Bugfix: Fixed an issue occurring with the FindTeleportSpot function when finding locations for spawning an Actor (before BeginPlay). It now applies the proposed Z adjustment to all XY position permutations, instead of only applying it to the last of the XY-only permutations after all of the XY-only options failed. When an adjustment axis is nearly zero, more permutations are tried rather than duplicating the four axial permutations. The behavior of the FindTeleportSpot function for Actors that have begun play has not been changed

HI COMUNITY- busco programador en blueprints for a fiu minits to talk
rose glen
@mossy nymph @dim plover , thanks for the input, i will go dig into the crash now โค
wary wave
@dim plover - I've not looked at any of the release notes actually, but that's a curious one
sounds like an actor is more likely to not be instantly deleted any more but at the same time, it's a minor fix, not an improvement
spawning is now just that little bit slower again, lol
acoustic pollen
๐ฎ
wary wave
for actors with lots of components it's not so much an improvement as exacerbating the problem
mossy nymph
like you leave actor spawning to chance the default algorithm will find a position @wary wave
wary wave
it can still fail to find a position - if what's above is to be believed, it will now however correctly try eight locations instead of five
the problem with actor spawning is it actually ALWAYS spawns the object - if it fails to find a location it then deletes it
it's kinda stupid
dim plover
Spawning at a relatively unknown position is always chance based, isn't it?
It's more or less just trying to find a good spot.
mossy nymph
its also not good enough for production
wary wave
depends on your game, your object, and your implementation, but generally speaking you should only be trying to spawn stuff where you know it can be spawned
mossy nymph
i'll know i can spawn an actor at location before i call the function
wary wave
pooling actors isn't a bad idea when you know that spawning them is expensive
serene birch
I guess the spawning code needs the object to exist to test collision with the world
so that's why it then deletes it when it can't find a location ๐ฎ
wary wave
@serene birch - yes; there's no inbuilt behaviour to precache the actor's bounds
mossy nymph
CDO always exists tho
wary wave
but implementing such a thing is frustratingly trivial
serene birch
note that the patch note mentions the new algorithm is only used in level start or so
wary wave
CDO is worthless because bounds are not yet valid
dim plover
I think it means for the TeleportTo specific to spawning.
wary wave
no, it's talking about Actor lifecycle, it's for any spawning behaviour
an actor is spawned, teleported to a location, then the collision is tested
if collision tests fails, it tries several other locations (depending on spawn function params), and if all those fail, it deletes the actor
serene birch
yeah I caught that error
wary wave
if you precached bounds at editor-time for actors that you know will have defined bounds though, you can avoid ALL of that nonsense and just skip straight to collision testing without having to spawn or delete, or any of that madness
serene birch
by "precached bounds", you mean like having a "spawning actor room" with enough room for anything to use for the initial spawn before you yourself manually place the actor at the right location?
wary wave
nah, calculate and save the bounds whilst you're still in the editor
literally save it into a vector
do nothing at run time except use said bounds for collision tests when spawning
if you know the actor bounds aren't going to change, you can avoid a hefty amount of spawning cost
because you're not teleporting umpteen different components around for no damned reason
serene birch
I see
wary wave
when your actors have 20+ or even 30+ components, you save a lot on performance, hehe
another option is to determine their bounds in advance when spawning stuff as part of your pooling system, if you are using one
serene birch
how do you pass that info btw?
wary wave
edit the base actor class and rewrite the spawning functions
wary wave
if you have an actor pool, you can cache the bounds once the actor has been spawned during initialisation - then use that bounds value to do your collision testing prior to teleporting the actor
that approach would not require modifying engine code
scarlet birch
That's pretty close to the approach I use now most of the time.
At least with anything that has to spawn frequently
wary wave
aye, makes perfect sense

What bp node do I use to know when a certain level/session is loaded/joined? I am working on a multiplayer and right now I have the character getting spawned by the player controller, it works, however doesn't distinguish between my menu map and a joined session.
mossy nymph
@real hound use a different GameMode class
real hound
Mm, I dont know if that will sort it. I already have default pawn set to none.
ITs more of a question of how can I more appropriatly spawn the character from the player controller.
midnight bolt
is there no plugin for bulk rotation of models on scene, like add +90 on Z? someone linked to bluetility recenetly, but i was hoping for a simpler tool
mossy nymph
main menu one doesn't spawn the characters, the game level one does
real hound
I am trying to do a drop in drop out thing like Rust, so having a default spawn isnt ideal
mossy nymph
and the best place is override of HandleStartingNewPlayer in GameMode
real hound
Hmm ok. I'll look into that override.
mossy nymph
its BP exposed, if that matters
if you don't call Parent, it will not use the default logic to spawn a Pawn
real hound
Yeah I have done overriding in the camera manager before.
If I dont call the parent? I dont follow that though
real hound
Ah
mossy nymph
calling a parent node (by right click - add call to parent) calls the default implementation, to which you can then add in BP

Is there a way to use multiple NavMesh to control NPC with different setup (some with an "Agent Max Height" set to, let it be said : 1 meter, to allow NPC to jump over barriers... and some others with an "Agent Max Height" set to 0 to have a NavMesh which delimit the barriers and therefore, in order that the "non-jumper NPC" know that they have to get around the barrier...) ???
Because if the "Agent Max Height" is set to 1 meter or a certain high, the non-jumpers NPC believe that they can jump (just like the jumpers NPC) but they can NOT ! So they get stucked behind the barrier... ๐
mossy nymph
NavModifierVolumes combined with NavAreaClasses and NavFilters
NavModifierVolumes have a NavAreaClass
NavFilterClasses determine which NavAreaClasses are passable, which aren't
and then you set NavFilterClass to your PathfollowingComponnet/AiController/MoveTo

hi. i try to post in LOKING-FOR-A TALENT channel but i cant.
mossy nymph
check pinned posts, it will tell you how to do it
mossy nymph
go on #looking-for-talent and click the pin icon top right
pastel veldt
thanks
mossy nymph
you can also use NavigationLinks for the jump over the barrier, and cut out the NavMesh in the middle
they also work with NavAreas/Filters

@mossy nymph It seems to fit perfectly with what I'm trying to do ! Thank you ! ๐ I'm gonna work on all this !

guys is there a way to make the texture randomized instead of being repetitive like on this wall?
plush yew
@summer turret I'm a noob who don't know much on texture but I saw this tutorial once and I think is what you want to do : https://www.youtube.com/watch?v=De8DUod26Mg

thanks man ill take a look at it
lilac sparrow
hello everyone , im new in game developing so i followed a tutorial on youtube ( climbing tutorial VR ) and i follow in every step carefully + i did it twice and when i finish and i start playing i can grab cubes but when i try to climb everything turns black then UE crash ... any solution or can someone tell me what happened
grim ore
when it crashes you should see a crash reported with an error?
lilac sparrow
yes after a while
grim ore
if you have the debugging symbols installed it can help point out the error, besides that I don't think we could even guess
lilac sparrow
i dont think its installed i will install it , thanks by the way
grim ore
if you get an error we can check it out. If it takes a while before it crashes it sounds like maybe a loop that gets out of control and sucks up memory

Is 4.23 a big upgrade?
storm burrow
the changelogs read amazing
๐
so much good stuff
best update in a long time from my POV
placid yarrow
If I have a project in 4.22, what is the best way to test it in 4.23 in such a way that I can take it back to 4.22 if necessary?
dim plover
Back up the 4.22 project. Upgrade to 4.23.
rustic panther
the best way is to create a source control submission for latest 4.22,up to 4.23, see if it works
placid yarrow
Thanks. I've never rolled back to a different engine version before. So I'm clear: I use Source Tree for source control. The current version of my project is committed on SourceTree. If I open the project locally in 4.23 and upgrade it to 4.23, if I run into a problem, is it the case that all I have to do is checkout the last commit that I made on 4.22? It won't try to open that commit in 4.23? Or do I then need to delete the whole project locally, pull it, and open that?
I'm a little nervous, because I have a lot of time in this project.
grim ore
if it's in source tree right now and it works then as long as you don't commit anything to your branch you can 100% go back to that version
placid yarrow
Awesome. Thanks!
thin tendon
Is there a way for me to get the height of the ground at a certain point. For example if I want to spawn a character at ground level
grim ore
when you open the project in the newer version it will suggest you open a copy as well so just do that and let it copy to a new folder and test in that. If all seems good you can open the original again and convert in place
placid yarrow
@grim ore , I'll do that as an extra precaution. Thank you!
grim ore
at the worst if you convert, and commit you can always go back to the previous commits on a new pull and be fine then just recommit again past the "broken" upgrade lol
or yeah roll back to a previous commit in the stream
@thin tendon the easiest way is to do a line trace from above the terrain down and then you have a hit point for the ground level
thin tendon
So like a ray cast?
grim ore
yes
thin tendon
Thanks mate
ancient otter
How can i make it so if a constant = 1 then something happens, but, if a constant = 0 then something else happens in a material?
ancient otter
basically i want to make it so you can select 1 or 0
and if its 1 then it uses a texture
if its 0 it uses another texture
grim ore
does it have to be 0 or 1? what about true or false. if 0 or 1 you can use a lerp. if true or false you can use a switch
ancient otter
I am basically doing a script
with python
and i dont know how to change blend mode
so i will do kind of like a weird solution to that
i guess
grim ore
well if you are trying to do this in a material you can use a lerp, put a scalar constant in as the alpha and you put textures in the 0 and 1 inputs and then done
but if you are trying to do something else then you can set up the texture as a parameter and change it in script possible? I don't know what python has access to
ancient otter
i want to do it with a constant
I will do this
if texture_has_alpha_channel() == True:
So if this value is equal to true then blend mode will be translucent, that was my initial idea
but i dont know how to change blend in the script so my solution is that if a constant is 1 then the opacity will be 100
if it is 0 then opacity will use a opacity map
makes sense?
grim ore
it does, don't see why my suggestion doesnt work
unless I am missing something, are you creating materials?
ancient otter
instances
grim ore
and then setting parameter values on them?
ancient otter
Whatever, i guess i will use 2 master materials
1 for translucent another one for normal
polar hawk
yeah blend modes are one of those properties that define a lot of stuff behind the scenes
harder to just flip in a graph
ancient otter
also i need help with his
For some reason if i make my material translucent and two sided
the material gets like a whole or something
wich follows the camera
only happens if it is two sided
why?
polar hawk
thats a good question

I don't understand the principle of the NavModifierVolume. There is very few documentation about it and the very few videos that I've watched didn't help me to understand...
I've just put a NavModifierVolume on my level, I had a BP with NavigationSystem.NavArea in Parent Class and set this BP in the "Area Class" parameter of the NavModifierVolume's settings...
My NavMesh is still green. I feel like it does nothing...
What's is supposed to do ??? ๐ค
midnight bolt
hello, my UE 4.21 crashes when I want to go into one folder in my content where ihave sound cues only
it used to work fine
scarlet birch
@plush yew You have to select what it does in the details panel
plush yew
@scarlet birch Ideally, I would like to change the Agent Max Height of my NavMesh, here :
to set up to 0 for some NPC. Tt is currently to 144 so that some of my NPC can jump over barriers. But some others NPC don't need to jump. The problem is they sharing the NavMesh and so the "Agent Max Height". As a result, they "believe" that they can jump but they stay stucked behind barriers...
scarlet birch
Change your approach. Use AI to address different behaviors.
plush yew
I don't have the good approach ? Arf... So I'm totally lost...
scarlet birch
Instead of trying to have different Nav data, check if it should jump and then tell it not to jump
plush yew
@scarlet birch You're sure ? Cause if I say to my NPC to not jump with the Agent Max Height set like it is currently (and I think I don't have the choice : The NavMesh must indicate that the NPC can jump and where he can jump !), he's still going to be stuck...
scarlet birch
I'm not sure. I have no idea what you're doing. But if you have two AI and they should have different heights at which they can jump it seems to me that should be addressed with the AI or with an EQS and not with the navmesh.
plush yew
( Sorry, I just realized I didn't sent the good picture, above :
I simply would that some of my NPCs can follow my main character and avoid obstacles by jumping on it and some others by getting around it. I've already the following function. NPC can follow my main character. I have in the RecastNavMesh setting this "Agent Max Height" (on the picture) set on 144. So the "jumper NPC" can jump over small obstacles but "non-jumper NPC" (I have 2 types of NPC) cannot and must not. Problem is they share the same NavMesh (and so the same "Agent Max Height". And then like I said, they "believe" that they can jump but like they don't, this "non-jumper NPCs" just stay stucked behind obstacles... EDIT : Maybe I'm confusing "Max Height" and "Max STEP Height" but anyway...
( Sorry it was hard to explain... I hope I'm clear ! ๐ )
scarlet birch
I understand. It may be that you can place a nav obstacle of some type to tell them to move around it. That is not the approach I would use though. I'm sorry, I'm trying to help but I only use the built in Nav and AI a little bit and write my own for most things. My approach would be with the NPC its self to tell it to behave differently when it encounters the situation.
plush yew
Youre approach is better maybe... I don't know at all...
I think I'm gonna post a topic on a UE forum to see how others dev how to go about it...
or I'm gonna come back here later

Upgraded from preview 8 to 4.23 final and I deleted Binaries and Intermediate, regenerated, rebuild C++ and when I launch it does another rebuild and yet it fails with Try rebuilding from source.
toxic prairie
Thought your post was from today I was excited to update too
mint sequoia
Haha wtf, they still haven't disabled VR plugins by default
๐คฆ
Are they just ignoring everyone now
dark depot
its like tick on by default its staying on so ease of access stays
mint sequoia
But this isn't ease of access, its the opposite
Just because I have a VR headset connected doesn't mean I'm making a VR game every time I make a new project
dark depot
its so vr mode is easy
mint sequoia
Its catering to the minority, the minority who aren't inconvenienced when not catered to, when the majority is inconvenienced, so no
dark depot
yeah you also dont need tick on by deault it still is so its plug and play im not saying its what should be done
mint sequoia
No, they are completely different
dark depot
because the same mentality went behind the decision
mint sequoia
I don't think so
If they did this on purpose its just plain wrong
When you're making a game lots of stuff does tick, that's not related at all and just derails the problem
dark depot
you are missing the point.. i understand that but that isnt why its on by default they default it so people new to the engine dont try to use it and go why isnt this working. VR enabled by default is the same reason someone new can just start up the engine and have VR work
mint sequoia
Haha if you have a problem with tick being on by default then bring that up on your own
mint sequoia
Yes I just think its completely irrelevant
dark depot
im telling you the reasoning behind the default
dark depot
agreeded
mint sequoia
New devs have no business using VR before they've even learned how the engine works
And it doesn't warrant inconveniencing literally everyone else
Epic have been told all this, and many other reasons, and they just ignore it
So basically they have no good reason + are just gonna do it anyway
mint sequoia
I made a spring controller that has limits for specific axis and directions, made to solve the issue of helmet's clipping through the head because you can't clamp -Z to 0. It's here as a plugin if anyone wants it: https://github.com/Vaei/SpringBone/

normal burrow
mint sequoia
Be warned, in UE4.23 you can no longer have an array of a struct containing a TMap, it crashes the editor
mint sequoia
In UE4.23 particles are also completely broken (due to Initial Size node breaking)
Feels like I'm on Release Preview 1 ๐
wary wave
oh wow
and that went through what, 8 previews?
Epic really needs some kind of proper QA process on builds
I feel like they literally do the minimum testing on only the changes that go in, when they go in
regal path
Does web remote control is working in shipping build ?
wary wave
it was only a few versions ago they shipped a new version of the engine where you couldn't rotate a character FFS
mint sequoia
@wary wave There are still game breaking (for some) bugs with character mesh rotation, I reported it but the guy who responded couldn't understand the issue no matter how I explained it
So its still there
wary wave
delightful
serene birch
well they DID test the particles then since they had some changes in Niagara in the first place ๐
not sure how they could test those and fail to see a bug that just breaks all
honest vale
writing tests in general feels pretty cumbersome
wary wave
doesn't need to be a written unit test
literally just having some levels with specific content in it, and having someone open them and look at them is enough to catch these cases
"all particles are broken because scaling is fucked" isn't hard to catch
serene birch
was it broken in the previews too?
wary wave
I'd assume not, but I never touch the previews, so couldn't comment
I stay permanently one engine revision behind at best
warped tangle
is the mesh rotation bug you guys are talking about the one where things in BP editor randomly won't rotate until you restart the editor?
wary wave
when I spotted it, it was similar to that yes - the character mesh in the default projects could not be rotated in any way without first saving it and then restarting the editor
warped tangle
I have that happen all the damn time
random meshes, at seemingly random times. It's generally when I'm rotating a child component, it will just...not rotate no matter what I do. Editor restart is the only solution I've found
mint sequoia

Hey guys, should i use different struct for different type of attacks such as attack, attack that requires height, projectile-type attack?
thin tendon
Is it possible to search for files outside of your game during run time using blueprint? I basically had an idea. I want to search the players music folder for WAV audio files at runtime and add them to a playlist for the game to use
sudden agate
that sounds fishy.
Just give the enduser a single folder which you search at runtime
/Game/Music
for example
thin tendon
So you reckon just add a music folder to game directory. If I did that I reckon I would need to create an import window. So players don't have to search to find game directory. Thats why I was thinking of having it search music folder. Less set up for the player.
I want it to be so simple a child could do it
sudden agate
wtf are you talking about. your game already knows where it lies. no need to search for it
regal mulch
Iirc there is still a bug with TMaps not loading properly from config/text.
Means you copy a tmap with multiple entries (String, Struct for example).
And if you past it it overrides all entries with the first one
had to remove our config TMap cause of that
thin tendon
No not searching my game. An import window for them to find thier own music from the game and have the game move it over for them
regal mulch
My Plugin was loading Sound Files from Hard Drive
But it's not available anymore. So yes you can, but C++
Or Plugins
thin tendon
Ok thanks mate. that makes sense. I have noticed structures are a bit buggy in general
regal mulch
You will also have to get the wav file or ogg file into the USoundWave or whatever it is format
Cause UE4 can't work with the raw files like that
thin tendon
ohh ok so I need to find a way to convert it
cloud cobalt
Generally speaking this isn't easy to do
thin tendon
Its starting to sound difficult. Just seemed like a cool idea
cloud cobalt
Not to mention few people today will have music locally, so it's going to be random sound clips from the programs
thin tendon
Thats a really good point
cloud cobalt
You can filter by folders and length, and then read that etc
But yeah, unless it's really important for like, a creepy factor of playing their own music to them, it's a lot of work for not much
thin tendon
Yeah I think reading from file will be the easy part I already do that for the save system. The conversion stuff sounds like the tricky part
Nah I just wanted to give players the option to replace ambient sounds with music if they wanted
cloud cobalt
Give them a music volume setting, and let them play their own music ๐
serene birch
in the end, yeah
thin tendon
Yeah I already seperated the music volume
serene birch
there is little reason to code a "music player" in your game unless it serves some gameplay reason
just let the users use their favorite music player
cloud cobalt
(Which is going to be Spotify anyway)
thin tendon
I think steam has in built thing to do this anyway if I remember correct. Through the overlay
serene birch
I just use youtube tabs open in Chrome or Firefox ๐
Steam has a builting music player
thin tendon
ohh there you go not worth doing then. Seeing as game is steam exclusive
serene birch
I think most consoles also have that too? and a requirement for your game to mute the music when the user is playing is own from the system
thin tendon
Thanks for the chat guys. You guys just saved me from wasting a ton of time
serene birch
ah you do have the API to control the Steam music player ๐ https://partner.steamgames.com/doc/api/ISteamMusic

first person and third person are just templates, you can add those content packs to any project. UE4 didn't "switch" anything on your project
here's one solution to a similar problem
quick google search brought up a bunch of posts, I'd suggest looking around at those

Well if you're compiling shaders I'm not surprised your CPU is at 100%. Mine hits 100% every time I compile a large amount of shaders

all the code is dead
mossy thorn
No way to reduce the tread using event if take 1h to compile shader?

@foggy cipher dude all you have to do is redo the code that's there
Just drag off the not-red version of the references, call the function that needs to be called, and relink stuff
It's honestly not that bad

@mossy thorn Not that I know of, and that's not to say that you can't....I just don't know of a way
@foggy cipher your code is broke, you have to rebuild it....
Just start going down the chain and check all your code, looks like you're going to have broken references everywhere

Anyone had an issue with 423 where you play in PiE and, after some unknown time or event, it starts doing this weird rendering effect that looks like some massive headache-inducing blur thingy is being applied to everything when you rotate the camera?
warped tangle
@waxen lintel .....like motion blur?
waxen lintel
Yeah, it kinda looks a bit like that
warped tangle
I haven't upgraded to 4.23 yet, so I'm not sure if there's been a change, but have you checked the motion blur settings? You may have had it switched off in Project Settings in whatever engine version you were using before
and it may be on by default now, no clue
or check your PP volume(s)
waxen lintel
Yeah, of course, it's all off, and what's more this effect doesn't present itself until after several seconds(or minutes) of play
and then, once it has appeared, it's there from the start when i do PiE again
warped tangle
odd
waxen lintel
I've tried it in a new map with no custom assets as well
warped tangle
framerate stable?
waxen lintel
Ugh yeah, regretting it already... and an editor restart only fixes it for a few minutes

you check the motion blue settings on the camera itself?

i usually don't upgrade till the 4.xx.2 or .3 update either, but I have a RT project and want to get on the latest code as soon as its out
so i think i'll suffer with any upgrade headaches that might happen
mint sequoia
@fleet rain That's pretty risky in this release, so far I've found any BP with a TArray containing a struct containing a TMap will crash, and particle initial size is broken ๐
fleet rain
@mint sequoia thanks for the heads up. that's good to know, i'm generating a build today and taking a look at things. i did notice that with preview 8 some things were broken, but i didn't have time to track it down. so anything blatant like that could be a showstopper
mint sequoia
@fleet rain I have my impact sounds from hitting with a sword in such a TArray/Struct/TMap and they work, but if I open the character's blueprint where they're set its an immediate crash, if I refactor to empty the array it opens, if I then add something to the empty array its a crash
Just so odd how that didn't get caught
dim merlin
Hi, 'NegateFloat' node removed in 4.23, why?
fleet rain
that's really helpful thank you. i'm sure i'd be banging my head against that for hours ๐
I've had a consistent DX12/RT related crash that happens after so much time playing, I'm hoping that 4.23.0 fixes it. I've had it since I launched my game. But it was looking like with the preview builds that issue was becoming diminished, although I wasn't sure.
I'd deal with a lot if i could get that problem solved. Including doing BP scripts in a completely different way if I have to

hi, wich is the best method to connect cloud database service to android

@dim merlin There is a workaround listed
Workaround (partial)
Just create an empty level and set it as a startup map! It starts to load very fast as it should! Though then loading the original map will still be a problem, but I think it's better anyway.

Hi there. Quick Q: If I have a static mesh, with simple box collision, but then add that to a Pawn, does that collision apply or do I need to add collision as a component (and set as the root)?
real hound
How does a UE4 Server store player controllers, or joined player information? I am trying to do something like rust where you can rejoin and repossess your same pawn.
inner cloak
@silent frost Have you tried ?
silent frost
I've currently got it set to collision on the static mesh, but I'm getting strange collision issues (one where my pawn is rising up and over other actors, and a box trigger collision is blocking the player). Trying to figure out where my collision needs to be set, as I'm a bit lost as to why it doesn't work. My previous player character (not a pawn) worked, but the new player pawn doesn't.
Seems there's some differences between pawn and characters when it comes to using Static Meshes and Skeletal Meshes. Gonna have a further look into it but wondered generally what's the best way to add collision.

Hey, Im looking to decide between unreal and unity for a project. I was wondering how possible it is to create something with world bending effects in unreal. something like inception or this following image. is it possible? feasable? hard or easy?
what if i wanted to have the ocean meet the land at a strange angle for example
cloud cobalt
Does it need to be dynamic ?
low valve
dynamic as in be able to move and bend and change, water should have waves etc. but there is no characters running around purely landscape
rotund scroll
going to be equally hard
and it is going to be hard
if it's static it will be slightly easier, but still hard
fleet rain
its a good idea, very doable in unreal. and yeah created as staticmeshes would probably be easier than trying to dynamically move around landscape/foliage and other unreal systems
and yeah you'd have to be a really good cg artist

guys, i updated after my game randomly crashed 4.22.3 and stopped opening my project. Now i'm on 4.23 and trying to launch on my android but is giving me stupid errors, one for an apple related plugin (that i'm not using and i'm launching on ANDROID) and one now on oculus related stuff... how do i disable all this things, in project settings only android is selected
the apple plugin one i resolved by coping a folder from 4.22.3 into 4.23
cloud cobalt
@low valve basically, heavily dynamic scenes are a problem in any engine
You don't see many games doing it for that reason
If you do it statically, without movement - with some sort of weird local gravity then UE4 would do it fine
If it needs to move, well, it's probably equally hard in both engines

Hi, is there a way to tell a Nav Modifier Volume to assign its effect (in my case : simply block the area for a non-jumper NPC, so I selectionned "NavArea_Null" - the default parameter - in the Area Class setting just like there :

Hi

Quick cuestion
plush yew
Is there a way, so, to tell a Nav Modifier Volume to assign its effect JUST TO ONE TYPE OF NPC ?
dim merlin
@mint raptor thats not the problem

I have a text box,, and i have an event on text changed wich has text as output,,,,
What node do i need to get the text box itself refference from its text property ??
Is not a get parent
dim merlin
just moved my project over to 4.23. Im experiencing a huge loading time (like 10 seconds) when i press play in the editor. Anyone has a idea?
plush yew
In other terms : to tell a Nav Modifier Volume to to this effect on the Nav Mesh (see the crates on the screenshot below : they are not in green thanks to the Nav Modifier Volume) JUST TO ONE SPECIFIC CLASS OF CHARACTER ? :

@low valve regarding your issue, have you thought about turning the landscape and the camera view so that water plane is straight in scene

How do you add a full screen widget as a child to an onscreen box and not have it scre up its relative locations?
scarlet birch
Overlay?
Make them both children of an overlay rather than parenting one to the other?
@plush yew I really think you're causing yourself a lot of headaches by taking that approach and that the reason you are not getting an answer despite asking over and over again is that, as far as I am aware, Navmesh is not designed with the idea of having multiple navmeshes covering the same area. It would be much simpler to use EQS or another method to determine the state of the world around the NPC and then some sort of AI logic to determine what action to take.
low valve
@inner cloak yes, i wonder if unreal has the equivilent of this amazing plugin? https://assetstore.unity.com/packages/vfx/shaders/curved-world-26165
scarlet birch
@low valve You can do that with materials and a parameter collection.

@cedar snow why wait for a .1

hey people
how can I identify whats the poorest in my PC for my Unreal Editor? What should I replace first? Is there some sort of performance checker?
grim ore
replace it all then you have no problem ๐
but the real answer depends on what you are doing and what you have
I guess a real basic easy way is to load up your project, type stat unit in the console, and see which one is taking up more time the cpu or gpu lol
left mulch
@grim ore im using it as alternative renderer, so its always in a state of sequencer, cant like, run a game and hit stat unit to see performance wise coz i have no actual game
grim ore
you can run stat unit in the editor
left mulch
recently UE started to crash my GPU drivers left and right, despite my GPU not showing any signs of death or misbehaviour. Runs perfectly in all other games and doesnt give me a single reason for a worry.
I just typed it in console and it returned me nothing. Doing something wrong?
grim ore
thats the wrong console, hit your ~ key in the viewport
left mulch
uh, same?
grim ore
weird then
left mulch
brings up this little window in the middle but they are same windows
so it just typed over here
grim ore
yep both should have worked, I just tested. It should give you a stat display in the top right of the viewport
left mulch
oh
yes
it does
it just disappears when im out of the viewport
frame, game, draw, gpu and rhit
what do they mean, if u dont mind?
grim ore
how long it takes for each part, so the higher the number the longer it takes.
so game is primarily CPU, GPU is primarily GPU, etc
left mulch
Yea I see, but what part "Draw" is?
left mulch
google gives me registered health information techinichian
oh thanks
Thanks, amazing link, sorry for me stupido
ripe saffron
Just wanna say thanks to at @MathewW for all your tuts. Would have been in trouble many times without them.
grim ore

left mulch
Aight it says whats the meaning of digits in here, and I read it as Im getting bottlenecked by rendering thread coz my draw is 3.5 and game is 7.5. But, uh, sorry again my stupidity, what is the difference between game and draw? I just genuinely dont get the specific words I suggest?
I guess im lacking rendering power like GPU CPU? but what is game thread then?
cloud cobalt
game = game thread
left mulch
uh
grim ore
game thread would be stuff other than drawing basically. If you have any stuff going on like moving objects, cpu particles, etc.
grim ore
so event tick being used alot might increase the game thread as an example
plush yew
Hiii does anyone happen to know how I can import a tiltbrush model into unreal?
cloud cobalt
Skel would be anim thread
left mulch
dont have that thread in stat unit duh
grim ore
if you want to see the exact issue there are a ton more stat XXX commands to drill down to the actual issue
left mulch
okay, i suggest same link can give me more info
plush yew
@scarlet birch Ok but some other guys say that is possible so I don't even know what the hell anymore... ๐
(Moreover, I did never use EQS... ๐)
scarlet birch
Did they share how ?
I mean anything is possible if you want to tear into the engine source
plush yew
No, they didn't know... ๐
scarlet birch
๐ฉ
plush yew
@scarlet birch For example, a guy on a french discord (sorry but I'm french ^^) has just tell me :
I translate ๐ :
( in resume )
It seems to me you can create many Navmesh bound volume with different properties
You could create 2 types of agent and attribute to each of this types one navmesh and exclude the other
grim ore
the agents cant be auto assigned is the biggest issue, they are automatic based on your settings for the capsule and nav mesh settings
plush yew
Then you could have a mesh for the creature which jump, another for those which don't jump
scarlet birch
Why would you want to create two separate navmeshes though for something a few traces or an eqs could solve?
plush yew
@grim ore Oh sir ! I saw the video of you about the Nav Modifier, one of the few about this on the net. Thank you so much for all this videos ! This one was very clear like always but it didn't say if it's possible to assign Nav Modifier to one specific class character (and exclure anothers)
But now you say, if I understand well, that my way to do could do some issues... ๐ฆ
@scarlet birch Simply because I'm a newbie and I don't at all how EQS works ๐
Using two separate navmeshes or NavModifiers to block some areas for just one kind of character would be so easy and convenient... But as I don't know if it's possible... ๐
grim ore
how are you moving the ai?
plush yew
with a pawnsensing and a AI move to
( in resume )
and a jumping function for some of my NPC
( so that's why I set the Max Step Height (a RecastNavMesh parameter) to.. mh... around 200 I think... If not, this NPCs could not jump )
( but then, the "non-jumper" NPCs share this "Max Step Height" value and then, believing that they can jump... don't ! And then get stuck behind barrier... ๐ฆ )
scarlet birch
Why are you using pawn sensing instead of AI perception?
plush yew
( that's my problem... Either I reduce Max Step Height and so my jumper NPCs cannot jump but it suits well for my non-jumper NPCs (they can get around the barriers) ... Either I raise Max Step Height and so it's the opposite : my jumper NPCs can jump but my non-jumper NPCs get stuck... )
@scarlet birch Because I know only this method, simply, again... ๐
( the pawn sensing )
scarlet birch
I'd suggest working through some tutorials on AI, EQS, AI perception, AI controllers, Behavior Trees, Tasks etc... for a day or two and then coming back to this.
grim ore
the weird part is using filters should work for this but I can't seem to get them to work right lol
vast fjord
how can I solve this? i'm deleting unused levels to make space
grim ore
oohh.... its because the default cost for an obstacle is 1 million lol
vast fjord
I'm trying to run the editor with that command but it's not working
