hello guys, how are you all?
does anybody know if there's any way to extend or create project filters, ideally without extending the engine itself (maybe using python scripts)?

any way to limit the number of simultaneous shaders being compiled? maybe I'd like to watch some youtube while I wait 5 hours 😛

@lofty hollow The CMC does 8 iterations per tick
Also called substepping
So in each tick, instead of moving once, it moves 8 times 1/8
Which gives it a better chance to detect collision, specially for fast moving characters.
lofty hollow
does this have anything to do with fps?
frank escarp
@regal mulch nope
not 8
its about the max simulation time
and i think thats on seconds?
so 0.05 is 20 iterations per second
CmC will run once per tick if you are at more than 20 fps
but if you are lagging hard it maxes out at 8 iterations
lofty hollow
What im trying to do is like apply acceleration and make it consistant at all framerates... so like what do I want it to be then?
like would i want it to be 0.05 and 3 so that its equals 60 maybe?
regal mulch
These values have nothing to do with consitant acceleration
For that you should make use of the DeltaTime
regal mulch
Wasn't acceleration Velocity += Acceleration * DeltaTime?
And then Velocity * DeltaTime for the actual move?
lofty hollow
im doing * deltatime for the addedspeed
basically
maybe the problem is that friction is still applied when i land which causes me to lose more speed the lower the framerate?

Hej guys im kinda new to unreal coming from unity i have just finished my 3D studies and want to create a game, but with all the knowledge thats out there its been a jungle i want to learn not how to do one thing but learn all the tools so i can think for my self and create what i think off, not with iut trial and error but i think you get the point. So if any od you fine folks would DM me the best place to begin to get a understanding of the massive engine i would really appreciate it. 😊

No joke the doc is pretty good
Otherwise, go on youtube and ave a feild day. There's ton to break into the engine 😄

yup, docs are a good start point. if anything else, mathew waldstein has a great youtube channel, as well as some blog entries by orfeas eleftheriou
if i'm not mistaken, waldstein himself roams around here as well

Hi guys, so i have a texture wich is all black expect some parts, and, i would like only the white parts to show up in the albedo. How can i do that?
I have a constant vector 3 wich makes a color, in this case green, and i would like the white parts of the texture to be shown
fierce tulip
multiply it with the green color
ancient otter
Well yeah but when i do that all the texture goes black
because everything besides the white part is black
fierce tulip
black = 0
white = 1
anything multiplied by 1 stays the same.
ancient otter
wym?
this is the texture
Its basically all black and i only the white dots to show up
fierce tulip
shaders are often basic math
so if you have a mask, anything thats multiplied with black (0) will be black (0)
anything multiplied with white (1) will stay the same.
now that you have those white dots, and want to add it to the albedo texture, you need to subtract the white first, and add the white parts back.
though, there are also a variety of "blend" nodes, try some of them
blend lighten, blend screen, etc
same as photoshop
fierce tulip
got it working?
fierce tulip
hey if it works, it works
ancient otter
Is there a way to make the whites stronger?
fierce tulip
power node, multiply node with higher than 1 value (saturate afterwards), adding the same output twice and saturating, many ways to do it
power node is basically contrast
ancient otter
oh ok
Look at my reference
Now im adding the white dots since everythign else is almost done
fierce tulip
https://docs.unrealengine.com/en-us/Engine/Rendering/Materials/ExpressionReference
this is basically my bible
ancient otter
the only thing besides that is adding also white on some edges and stuff
fierce tulip
math is interesting
fierce tulip
there are ways, but its really bad for performance so I wouldnt do it
fierce tulip
spiral blur is the easiest option
ancient otter
How do i use it?
fierce tulip
iunno, i dont use it
ancient otter
looks like it makes the actual render blurry
dire torrent
Anyone know how to use OutputNoDepthBias with SoftOpacity for materials? My materials have black texture and don't know how to fix...
ancient otter
@fierce tulip What im actually looking for is making my normal texture more blurry so its wavy and smoother.
Not the mat to be blurry
It would be like adding ghaussian blur to the texture on photoshop

so by changing my texture group to mobileflattened, my unstreamable textures is decreasing and my streamable textures is increasing. I just have not seen this explained anywhere.

Error: Loading non-streamed mips from an external bulk file. This is not desireable. ??? anyone else run into this error?
plush yew
Does anyone here use their blender rigs in unreal? And if you do do you use leg IK? Because I cannot for the life of me get it to work. I've been tweaking export/import settings for a week now. Someone suggested it might be the bone axis settings and moving them around definitely does affect the lower and upper leg bones but the foot is always rotated in a weird direction no matter what I do. It seems the foot is being rotated to a position equal to what it would be if I zeroed its rotation out in the skeleton
@plush yew from what ive learned you have to scale blender rigs at least for the collision meshes or they will be .01 the size. You have to scale the armature (and mesh) in Blender by 100, apply it and when you export it set the scale to 0.01
Beware though that this might mess some animations up that use bone location
you have to go to the keyframes and type the location values "*100" I think
I'll check that out, thanks! At the moment I scale the skeletal mesh by .1 on import to UE4
Yeah I think that would make the ragdolls even worse
https://i.imgur.com/lvowUJn.png Just as a reference
Hm did you check the bone rolls?
In blender?
yep
should the rolls be 0?
Usually, I know it can make difficulties with bone rolls
Those are just more reference pics
I know the IK setup is wrong in the bottom one I was just checking different settings when I took the screenshot. Okay, next thing I'm going is changing the scale and then scale and roll and I'll post those results. I've found multiple threads where this issue was happening and no one ever had an answer so hopefully this is it!
Well, scaling it doesn't seem to have helped, I'll try the roll next though
Ah, roll didn't do it either. Thanks for the advice though! Maybe tomorrow I'll upload a 30 second video of me making a rig and putting it into UE4. I'm probably just doing something wrong

pulsar fractal
Hello, I’m a bit of a noob and I’m trying to copy over a variable between characters to merge two that I like, but I’m not getting the array option that I want and that is present in the original blueprint
I just looked into child/parent blueprints. Can I simply make one character BP the child of another and use the child to play as it should inherit the parent’s whole BP? How would I do this with 2 existing BPS?
the pictures and other text can be disregarded, sorry for being a noob. That explains it much better^
dry moon
Yeah its best to have a parent and child
pulsar fractal
dry moon
so you only need to modify the parent and thus all children will benefit without needing to modify them all again.
pulsar fractal
Okay, I want to merge these two, how would I make one the parent?
dry moon
You'd need to make one of them the main, move over any code from the non-main to the new main
I don't think you can copy variables from one BP to another
you just need to readd them
pulsar fractal
Okay. But the functions will be inherited right?
pulsar fractal
Thank you so much, it turns out I could reparent one and I didn’t even have to remake the variables. But how would I call the parent?
Sorry nevermind I figured that out. However I’m just getting camera issues now where now that they’re merged, I can’t look up or down with the mouse

Is there a way to keep cloning objects in a level without making a separate entry for each one in the world outliner?
weary sun
Does anyone have idea why would mesh stay invisible in both level-places actors and newly spawned actors unless i open it in mesh editor? Feels like it doesn get loaded until I forcibly open it myself
Yeah nevermind, exporting fbx and reimporting fixed that
edit: in fact no, it was fault of soft referencing mesh. had to refactor my stuff to use regular references and now it works
too bad but i can live with that
crisp fable
any lone developers or small teams here use any project management software and can recommend anything?
beyond task lists i'd really like something where i can reference various assets and give them notes like "hey these sound files might be good for X"
south ridge
Google Docs 😄
dim plover
I don't think the problem is with soft referencing but rather how you load them. Although, this wouldn't fix your invisible in level issue, without some weird set up, I think.
weary sun
how should i load them if so? my stuff is like i have item with soft referenced mesh variable so i could get class defaults and use this mesh for UI
dry moon
@crisp fable I'd recommend Trello, you can create cards for different ideas by having different sections
and you can attach images to them as well
dim plover
It sounds like you're not actually calling load.
dry moon
and other types of attachments as well
crisp fable
hmm
weary sun
@dim plover i'm not, my bad. however i cant find that load function, care to point me?
dim plover
Typically I call TSoftObjectPtr.Get(), and if that's nullptr, then I call load (async).
It's a little hard to follow, but it's in https://api.unrealengine.com/INT/API/Runtime/Engine/Engine/FStreamableManager/index.html.
Which you can get from UAssetManager::GetStreamableManager(). I think it's called.
weary sun
so i guess i would need to expose that to BP myself?
dim plover
I think I saw a BP one, but I'm not sure if it's this. I think it's called Request Content?
dim plover
The BP node does probably exist, afterall, soft references can be made in BPs.
Anyway, if you do set up your stuff with soft paths, you'll need to set up your project so that it actually does cook the content when you package.
weary sun
I see LoadAsset in some screenshot at ueanswers however can't find that node
ah got it
its async so i cant put it in construction script
seems like sync version is c++ only
dim plover
Async is probably what you want.
weary sun
In my case i really want to use construction script (so when I put my item into level it would load mesh by soft reference and set it to staticmesh component)
unless i can avoid this limitation by exposing some stuff from c++ i dont see how would i do this
dim plover
You could wrap ConstructorHelpers with #if UE_EDITOR in the classe's constructor.
So that, in editor, it loads the mesh and assign it to the staticmeshcomp.
weary sun
Will look into that thank you!

Hello guys I have a problem with my project
I made blueprint for when I move into one collusion and press "E" to open one widget
but it doesn't opebn it and it has an error
and one more question where to pin my message log to see the whole error not to move the cursor?
it is here:
grim ore
click on the Add Child node in the error and fix the problem in your code, it's tell you what you are doing wrong.
plush yew
okay
I fixed but now it doesn't show me errors
omg
the problem was that I made my bp in wrong widget
after I moved it into the correct it doesn't work and doesn't send me errors
hmm
what to do?
trhis is the campfire
this is the bp of it in the event graph
I will send you my bp taht is in thirpersoncharacter bp into blueprints.com
grim ore
whenever you have a problem using "it doesnt work" is not a way to fix it. You need to describe the desired effect and then say what is actually happening. It doesnt work could mean your campfire objects are falling thru the world or your player is farting rainbows too soon.
plush yew
this is
okay
but it must work like this:
when I start te game I am on level
and there is a camfire
when I move to it I enter a box collusion
and when I am into this collusion and press "E" it must show me this:
this for now
I sent you upper the bp in thirdperson character to see
I have two variables boolean the both are false one is called already use, the other is "Is at Campfire "
grim ore
the first issue you are going to have is you are not checking to see if your player is walking into the campfire at any point
plush yew
I found where is my issue
I made the bp opportu?
I exhange this to thsi
and I have errors
ivory gate
@plush yew no way u watches enough tutorials yet
plush yew
ivory gate
Watch @grim ore tutorials he has a lot that r rlly good
Read the error
It said read NONE
That means it’s trying to use something that’s not there
spare steeple
@plush yew you need to cast OtherActor on the overlap event node to the character, not player character 0
probably where the errors are coming from
plush yew
a okay
spare steeple
but that change alone wont fix whatever your issue is
plush yew
I will try
hmm
it writes me only not visible
but this is the bp where I wrote not visible
I want when I go into the box collusion and press E to show me the UI Widget, to disable the movement, when I press again E to hide it and to can walk
spare steeple
you need to show more blueprints
spare steeple
that bp doesnt create the widget
plush yew
yes
spare steeple
does the widget already exist and has been added to the viewport?
spare steeple
you need to reverse the outputs of this branch
if already open is false, it goes on to set it to false
so it will never be true
and vice versa
plush yew
okay so if it is true to set visibility to hidden?
and the other is if it is false to set visibility to visible?
spare steeple
try making the false output go to the top and the true output go to the bottom
because right now that will never change the value of already open
spare steeple
yes
spare steeple
try it
spare steeple
what are the errors
spare steeple
that means the widget doesnt exist
plush yew
I need to make it with create widget?
spare steeple
like that
plush yew
yes I know it
I made varable and get it to don't make with create but it doesn't work without create widget omg
spare steeple
yeah
you need to create an instance of the widget for anything to show up
the best way to do it would be creating and removing it instead of setting the visibility
but for simplicity right now
and to keep your code as it is
create the widget on begin play on the character
plush yew
I don't want to add it from begn play because there are other things on begin play
yes I forgot it
but what to do for the true part?
plush yew
okay
spare steeple
so the actual variable has a value
do that where it should become visible
and when it should hide
do that
spare steeple
np
plush yew
but
When I want to remove from parent I want to save the changes in it because after I make this the next thing that I will make is to put woods and when you have 1 wood to build the campfire you will need to have 3 and when you iwll put one it needs to save tthis but with remove from parent it doesn't save maybe?
@spare steeple
spare steeple
does the widget change based on any of that though
if the widget doesnt change then its fine as it is
plush yew
what?
spare steeple
does anything on the CampFireBuild widget change when you activate it
removing the widget doesnt have any effect on anything else
plush yew
I didn't understand it again
😦
so when there is a tree and it must three let you remember that you put this tree when you get out of the fireplace - do you understand? I do not know for now how it is done, but let me do that all that now has a hell problem and then I will deal with him-ok?
@spare steeple
yes I fixed it thank you

our Mathew
is he has a tutorial how to make inventory action bar? @regal mulch
regal mulch
No idea.
light thunder
Trying to think about this logically - if you had a fuel gauge with multiple lights (25, 50 percent,) and so on, what is the simplest/best way to handle toggling the materials to make the lights flash based on fuel level?
a series of booleans could work but that seems...crude...
i'm wondering if there is some float function I haven't thought of
light thunder
it's like waterfall/cascade, so from 100, down, they will flash then go unlit
so as you lose your fuel, the lights go down as well
my old setup works but i'm trying to learn a better way
regal mulch
Can't fully picture it, but what keeps you from handling it as a steppt progressbar?
light thunder
I'm assuming there's a function aware of
the asset itself, I don't necessarily have time now to make a new one/widget that looks in the style I'd need
regal mulch
A Material with a Gradient to mask out the lights that should be off
And maybe a second one for the ones that should be on
And one for the ones that should blink
light thunder
ah, so I could use a material function instead of manually setting the material itself from a outside BP
regal mulch
Well, you def need to tell the material the percentage
Given it goes from 0 to 1
Your gradient space also goes from 0 to 1
So if your fuel is 50%, you set a scalar value to 0.5
light thunder
to help you picture it - this is an old asset but i don't have time to refactor or make new ones much
regal mulch
And that can be used to do your gradients
light thunder
regal mulch
Well technically that could be one Material
But I'm also not a graphics person, so maybe just ask in #graphics about it
I would probably work with gradients and blend between the states
And drive the gradient by a 0 to 1 percentage value
For the different colors you can always make material instances
light thunder
Yeah, i should have done that when I originally started this, but that was a long time ago
plush yew
what is this cool? @light thunder
light thunder
for a virtual pump panel for firefighters to break so they don't break a real one and burn down your house and kill everyone and waste all the water in the real and kill the whales
@regal mulch There's no switch on float or int even?
that's kinda what I was looking for I guess
regal mulch
In a material?
light thunder
just in blueprint in general
light thunder
ah so it does
regal mulch
That would mean you check on floats being equal which you never want to do
light thunder
I visualized it more as a hey, when the float is between 1.0 - .75, do this thing, when it's .74 to .50, do this thing, and so on
regal mulch
That's an inrange check
light thunder
but I'm still doing multiple in range checks I guess
pulsar fractal
Hello, I have reparented 2 actors successfully so that one inherits the other’s functions. However, I’d appreciate some advice on how to parent the animations from one character to the other, so that when I go to my blueprint of animations, I’d have every animation from BOTH characters listed there.
So far I tried to parent one animation blueprint to the other, having the base parent be AnimInstant, no luck
I apologize for the phone picture, but discord won’t open on my PC
I basically want to merge the animations so that when I look at either of the Asset Browsers for either the parent or child character, both sets of animations show up
pulsar fractal
I should add that both characters have their own blend space and were independently made to be completely functional with their animations. I’m just trying to do some parenting/merging that will keep the blendspaces functional for their animations and all that

if i understood correctly, you need retargeting

Would it be possible to realize a game like far cry with UE? 🤔 I mean in terms of graphics and gameplay complexity
pallid compass
your not entitled to have your question answered
fierce tulip
@gritty coyote eventually, if you have years of practice under your fingers
pallid compass
and a big team
azure shore
yeah pretty sure ue4 can handle that
fierce tulip
@azure shore also, marto's question is very "generic" while yours is very specific
azure shore
I see
well ok then, basically how other than radial force can I just push physics objects
gritty coyote
@fierce tulip I mean why are most of games made with UE more like fornite or astronner and games made with CE r more realistic?
fierce tulip
iunno, not a bp/coder person. you might be better off trying #blueprint
azure shore
oh...
fierce tulip
@gritty coyote thats a misconception.
azure shore
there are loads of realistic ue4 games
in fact you have to go out of your way to make it look cartoony
gritty coyote
sry i don't really understand what you r saying 🤔
grim ore
the default FPS template uses physics to push objects using impulses
gritty coyote
yeah looking at that its true that it looks really realistic

hey everyone, did anyone try to develop using ARKit?
fierce tulip
@gritty coyote if you are just starting out, really. try making a break-out game, or pong, a pinball machine, flappy bird
else you'll hit so many walls that gamedev wont feel like fun
grim ore
Far cry uses a modified Cryengine so maybe do it in Cryengine or Lumberyard?
gritty coyote
@fierce tulip yeah for sure, may you give me an exemple of game that i can try making myself for the beginning (i mean an exemple that can actually be played like a game on steam or just on ytb)
@grim ore ok but in which case would it be better to use UE? 🤔
@pallid compass how is pinball to hard to do? 🤔
pallid compass
Physics, balls, paddle system , reaction, multi scoring formula, multipiler
etc
break it down
gritty coyote
true^^
but i actually don't really understand how difficult it is because when i'm watching some videos on ytb it don't seems to hard to do all this level art, physics management, sound etc....

hello everyone , I have a finished small game i made in August 2018 and i just deleted it from Google Play Store because literally no downloads(To be expected xD)it is mostly UMG but i was hesitant to publish it because blueprints are mostly uncommented . Should it publish it on the forums?

gritty coyote
and regarding the assets which r for exemple in the cry marketplace, can't i just take one of them and place them in the environment editor in CE and it's fine? what else have i to do on a TREE? 😅
leaden garnet
No, it's not allowed to rip off an asset from CE store to UE
leaden garnet
Check the terms

But here's the thing
If your entire game is marketplace art, players will notice.
It'll be a massive point in the negative column, and unless you're making up for that (and even if you are), you'll be panned

Is there an option to disable the "Double click on a BP nodes opens visual studio"? Or better, change it to ctrl+double click or something?
Oh, and while we are on the topic of changes to editor settings: Is it possible to set steamVR plugin as disabled for new projects as default?
leaden garnet
Why not create a default project, clone that project and use it as a template of sorts?
That way you don't have to worry about enabling and disabling plugins
Also within the project folder there's Config files, maybe clone those as well and close the new project, then paste em in there
hybrid scroll
That only works for new projects. Not for old ones, or those that someone sends me / that I didn't make.
Yeah, I can edit config, I can open the project and disable the plugin 😃
its not a huge problem. Just something I never remember to do until steam VR starts, my music stops, my mic switches to vive, etc.
leaden garnet
I don't own Steam VR anymore, I'm also not sure if you should ask this question here or in #virtual-reality

Well, its a general question about disabling plugins by default. The fact that its steamVr and not any other, doesnt rly matter.
But they might have some tips there.

Hey guys. Do you have any advice for someone switching to unreal engine from unity? I got really good at unity but now want to use unreal engine. I'm new and just wondering how long u guys think it will take for me to get good with unreal engine.
regal mulch
Can barely answer that, depends on your ability to learn.
Timeframe can be a months to years.
Also depends on what you are actually doing in the engine.
If you are good with Unity, then you most likely have a base understanding of what a framework is and how to utilize documentation of a software.
So grab UE4s documentation and start learning its framework.
Also, don't try to force Unity onto UE4. That happens easily and will make it harder for you to learn UE4.
If there is a system in Unity that exists in UE4 but works differently, learn the way UE4 does it instead of wishing for it to work like Unity.

Could somebody give me a hand with an overlap question? I feel like this should be fairly simple but I can't seem to make this thing trigger
Essentially I'm trying to make a simple fishing script for my game, when I have the fishing rod equipped it has a collision box - if the box is colliding with the water box then bool canFish is cast
but they dont seem to be detecting each other
So box is the part of the blueprint, wateroverlap references the other blueprint
They should be overlapping here but they dont appear to be triggering anything
@plush yew wondering if you could help me since you seem to be pretty knowledgable 😃 I'm a unity convert trying to make sense of blueprints still haha
Sorry, you had just helped the guy previous to me so I figured you were here - wasn't random. I have watched all of the intro to blueprints videos from UE and followed them accordingly, thus why I'm asking
thanks though
I try to use event but it says the direction isn't right

Anyone know if the merge actor function has an order for component merging?
E.g alphabetical or otherwise. I was hoping so but it doesn't seem to pay attention to the first added component in a BP
@stone fjord So you're trying to trigger overlap of a static mesh component or actor? Overlap events typically work if set up correctly
And by typically I mean always ; p unless there's a bug
@plush yew The Epic series/UE4 channel is probably just right
Eh nvm, can just use pivot at zero & put the BP actor at world origin prior to merging
gritty coyote
Hii guys, wich coding language should I learn if I'm working on unreal engine?( I've already learned some PJS )
timid flame
@gritty coyote C++, javascript if you want to use Unreal.js, Blueprints (which can also be nativized if perf is a concern) / any hybrid of those
gritty coyote
So that means learning c++ is a good option?
timid flame
Although JS is only a plugin / bp dependent I believe, so it's probably just ok for augmenting your pipeline
You don't need to learn C++ necessarily since BP can do most things, but knowing it is useful for if you need custom code/classes etc
I just use Blueprints at the moment, although I'm starting to dabble with C++ in VS some
gritty coyote
Okay that means I can start working on UE without trouble and if I have time I can continue my c++ course
timid flame
For sure. A lot of the terminology/syntax has crossover so both will compliment eachother
gritty coyote
Okay thx🙂 👍
plush yew
So I have a question aswell
So how much C++ do I need to know
Since blueprints cover most
timid flame
@plush yew It's kind of a question with a few answers. I would say since BP covers most things you could probably create everything you need with it, but that depends on the scope of what you're making
plush yew
Can I send a link to the idea that I have
I don't think it's alot especially with what games newer are doing
the idea that I have comes from a game in like 2010
timid flame
There's also times where you might think you need to create something in C++ since you don't know the relevant BP/kismet functions, but they still exist. Other times you know for sure that the only way around a problem is having custom code
You can PM me, up to you
plush yew
Ok thx
timid flame
If you're new to gaming/programming, be prepared to learn a lot is the jist of it
stone fjord
@timid flame theyre both actors from different blueprints. So I equip the fishing rod, then I'm using the box collider from that blueprint, and its only supposed to work when overlapping the box trigger
both are set to generate event on collision
its super strange, I've done a lot of colliders/on overlaps before and never had a problem, im sure its just something im not noticing 😦
timid flame
I haven't used them a ton either but usually things go ok. Are the collision channels at overlapall/blockall dynamic or?

Hey guys! What do you think is a reasonable polygon count for a vr gun the player should hold so not just a "lying on the floowr" asset?
cloud cobalt
Depends on the weapon and style and platform, but anything less than 10k tris is reasonable
regal mulch
Well this is fairly simple: Optimize it until you can't optimize it anymore. Then you have your triscount
If it still causes performance issues you gotta rethink the mesh
light lark
What do you mean by optimizing? so first modeling high poly and then subtraction polygons here and there or what?
light lark
Yeah
regal mulch
Lowpoly with maps. Traditionally you model the highpoly and then retopo it into a low poly. Then you bake the details. But I'm pretty sure with things like substance painter etc.,modeling the low poly and then adding details through substance is "easier" (?)
And your low poly triscount is important.
It's hard to say the weapon had to be xk tris
Depends on if you can remove tris without destroying the mesh
Or the rest of your game
light lark
Ah. Yeah! Sure. But why does it even has to be triangles? And is it enough if I simply triangulate everything at the end?
regal mulch
UE4 triangulates anyway
regal mulch
Kinda yeah. But triangles and polygons aren't the same or?
light lark
I mean. Triangular polygons are polygons too arent they?
regal mulch
In mean technically polygons is everything >2 corners iirc
So if you have an n-th corner polygon (not that this should be done) the tris counter wouldn't only double
light lark
yea. But its pretty important I think. I got a poly limit of 10k [The lower the better] but if its double the polygons if its un ue4 through exporting every square polygon into 2 triangles then
regal mulch
Well you have to count in triangles
light lark
damn 
cloud cobalt
You model in quads because it's better, but engines render in triangles
regal mulch
If you define your polys to have 4 corners (quads) then tris would be double yeah
light lark
yeah. cuz you cant half a triangle
yeah
you usually model in polys with 4 corners @regal mulch
abstract relic
Quads are just two tris with an invisible edge regardless

Yeah just wanted to establish that polygons can be more than quads or tris

I'm looking into creating a very simple Multiplayer prototype (2d, and simply moving one player on one client, and seeing it move on the other) just so I can see myself do it.
So my question is, can I utilize the UE4 as the server, or should I be writing my own server to parse and pass information between clients?
As a side thought, is there any way to error-check server side built in?
I assume not, but I thought I'd ask.
cloud cobalt
UE4 multiplayer works by server & clients being the same game
Except for actual dedicated servers, it's the same thing
With a different role
alpine leaf
That sounds like peer to peer though,
As you add more and more players it would vastly slow down the passing of information
Or am I not understanding?
cloud cobalt
No, it's not peer to peer.
It's server + 0 to N clients
It's just that by default, any UE4 game can act as client or listen server
listen server = actual player hat also hosts the game
There is also support for dedicated server, but dedicated server is really just a regular game without rendering.
alpine leaf
Mmm.
One player hosts and all other connects to them.
cloud cobalt
If you're planning on competitive stuff, or many players, dedicated is the way - still UE4, still your game code
alpine leaf
Tbh my project is rather small, I expect 4 players max, and not at all competitive.
I just thought it would be fun to try and write a dedicated server for myself.
Although a limiting factor is that I don't understand cpp side of UE4 very much.
I'll probably use the built-in server/client for my little thing. Specially since it'll be my first delve into Multiplayer with ue4
Thenaybe I'll transfer it to dedicated to learn that =)
Thanks stranger
cloud cobalt
Probably don't want dedicated for that
You'll need to have one such server online for every 4 players
Which is a lot of maintainance etc
Listen server is much simpler
alpine leaf
Yeah just a new instance of the overall server for every player that wants to create a room.
Simple concept, probably not as simple in practice,
It would just be for learning =) nothing crazy yet,
Thanks for all the help though, you've been immensely helpful
cloud cobalt
Let me be helpful again and advise you not to go with dedicated unless either competitive game or > 6-8 players
Just way more stuff to manage for no benefit

Anyone help me write this math into BP/code? I have a 2x = 4y, but when X comes in, it will not always be doubled (this is a water principle rule, as flow rate doubles in a system, pressure loss quadruples....I will know the flow rate, the change in the flow rate, and the initial (or static) pressure
don't know if I should lerp between x and 2x
regal mulch
@plush yew https://www.youtube.com/watch?v=wyC5vl64V9k
light thunder
real world example - you have a static pressure of 60 PSI at your hydrant - you are flowing 250 GPM....and your intake drops to 52....you can use this principle to estimate remaining flow - if you were to double the flow rate to 500, you would take your pressure drop of 8 (60 - 52) and quadruple it = 32, so your remaining pressure is 28
regal mulch
There, part 1 of an hour long video for drag and drop
Part 2 and 3 are also on youtube
If you follow that it will most likely give you the stuff you want
Or at least enough knowledge to then do what you originally wanted
regal mulch
@light thunder And now for non firefighters?
int PSI = 60;
int Flow = 250;
int Drop = 52;
int DeltaDrop = PSI - Drop; // 60 - 52 = 8
So far I got that
Now you say if 2 * Flow = 500 then you need to do 4 * DeltaDrop = 32
And then RemainingPressure = PSI - 32
@light thunder ?
light thunder
yes, but in terms of the flow rate changing, it's not going to double like that
I just need to get the curve/relationship from that doubling equation
regal mulch
Well what's the relation of 2 and 4?
Double -> Quadruple
What else can happen?
What's the math behind it?
light thunder
this is one of those things that once I see it, it should be a profound "duh" moment
example, the flow rate is 250 and the intial psi is 60......what is the delta drop when the flow rate is 350
do I just lerp between the 2x and get a scale and multiply that by the 4x?
something along those lines
plush yew
but there is difference between mathew and this live training because in the livetraining they create a bp class drag and drop operation-hmmm
regal mulch
@light thunder Well there needs to be something that goes from 2 to 4
Some math or a curve or so
That's something you must know
light thunder
it's a principle of fluid dynamics
regal mulch
I'm a Math and IT student
I have no idea about fluid dynamics ;)
Or rather bachelor by now actually
.>
light thunder
It's just math that's wet
regal mulch
Well if you write down all your stuff in some pseudo code
You need to replace the 2 and 4 by some variable
// Example, PSI = 60, Flow = 250, NewPSI = 52
int GetRemainingPressure(int PSI, int Flow, int NewPSI)
{
// 60 - 52 = 8
int DeltaPSI = PSI - NewPSI;
// What's next?
}
those are universal constants, the variable is the flow rate
light thunder
it's a ratio or proportion
regal mulch
Well you said "If you were to double the flow rate"
light thunder
The water velocity into a region with atmospheric pressure goes as the square root of the pressure difference by Bernoulli's law. So if you quadruple the pressure difference, you get twice the speed.
That's what that's based on
We got this, it's not like it's replication in UE or anything difficult
regal mulch
Maybe I don't understand what you want then?
Your original question was how to math out the double to quadruple ratio
Now you saw you have that stuff already
azure shore
@plush yew Im using texture object, not sample
