When I am deleting assets like blueprinjts I just made to play around with, nearly everytime, the app hangs "checking for root assets" is there a way to avoid this freeze/crash?

Particles from my particle effects appear to "jump" to their correct position when they move onscreen because the Actor that owns them is being updated offscreen
is there a way to eliminate this jumping issue?
spice urchin
@leaden perch yeah probably need to make the particles "Local"
leaden perch
Can you be more specific please? The particles are in a ParticleSystem ActorComponent
I am setting them a fixed distance from the center of the Actor and set the Actor to rotate using a RotateActorComponent
Marking the emiiter as "Use Local Space" removes the trailing effect I want to achieve

evening guys, anyone know how I can get unreal engine to run on my macbook pro? I upgraded to sierra and now it refuses to start due to me not having the latest and greatest macbook, it worked on an previous OS
leaden perch
What year is your MacBook Pro from?
If you are trying to launch 4.15, your Mac must support Metal
errant basin
late 2011, yeah 4.15, does this mean I'm stuck with 4.14? :/
leaden perch
Yes. As am I
I'm waiting for the new lineup of Macs this year. But I'm expecting to be very disappointed. So I'm a bit torn
kindred viper
Macs are for web developers! /runs away
errant basin
I cant afford a newer mac. seems like a bad business model if they're eliminating people with older macs
leaden perch
To be fair: I'm sure Mac developers are a pretty small chunk of Epic's user base.
And they want to move forward with their rendering technology. I don't understand why that means dropping OpenGL support, but whatever
errant basin
It's kind of annoying considering the feature set of 4.15 is quite good. Although, there may be a way around it, surely its just a console variable the engine checks on start up?
leaden perch
No idea. They probably check for the Metal dylib on startup
You could clone 4.15 from GitHub and check out the changes to see if you can hack around the limitation (PROCEED AT YOUR OWN RISK, of course)
errant basin
last time I tried to build from source it took hours and I had a silly error I couldn't get around -_-

Well, then you are like me: Massively SOL
errant basin
well i either suck it up or build in unity, shame really.

When the new Macs are announced, I will either buy a new one (if they are worth it [probably not]) or buy a 2015|2016 model on Craigslist

they're probably not.

mac makes ok hardware if you want a notebook
otherwise....yeesh, way to pay twice the price for an ornamental computer
if they'd ease up on greed and let people build them by hand it wouldn't be such a big deal. only computer builder i trust is ME
leaden perch
I'm not much of a hardware person, so I'm totally OK with a "works out of the box" solution that Apple provides. But with hardware improvements becoming less and less impressive thanks to physical limits of fab technology putting an end to Moore's law, the Apple tax is now pretty hefty. I agree that I wish macOS was available on non-Mac hardware
Might try for a Hackintosh if the new Mac line is not up to my expectations
But I don't really want a Linux experience....

Why does the lightsource pop-in/pop-out happens when outside of the screen? For example: There is a light source and it's rendered on screen. When the player looks away, it's not rendered obviously, but also it's light doesn't affect the scene anymore. I have to mention that I tested this only in PIE. Take a look at this GIF:

Hey guys, I'm trying to slow down an object by multiplying its velocity by a percentage every tick (0.995). Of course, at 144fps it'll slow down much faster than 60fps.
@144fps = .995^144 = ~0.48
@60fps = .995^60 = ~0.74
I was trying to use Lerp but it's not working
What should I do if I want to slow down an actor by the same amount for any framerate
brave horizon
Try a timeline/
floral heart
You can modify the multiplication factor by the delta time.
brave horizon
^ or that.
floral heart
So if it's 0.995 per second, then make it (1 - 0.005*deltatime) or somesuch.
daring elbow
ok, thank you guys. I'll try that
Sadly, it's not that simple. Ive used this math before to make things such as adding a force to an object
In this case, as I'm slowing the object related to it's speed, so that wont work
The only thing that this math will do, is multiply the object speed by the same amount independently of the fps
at the end, it'll still be the same as this:
@144fps = .995^144 = ~0.48
@60fps = .995^60 = ~0.74
floral heart
The delta time is the frame time. If you add up delta time over a second, it will total roughly 1.0 (+/- 0.00001) no matter what the framerate.
The blueprint node is 'Get World Delta Seconds'
daring elbow
I think this is exactly what you were telling me to do. But I get a completely different spin at 144hz and 60hz
this method is called every game tick
maybe there's something else interfering

vale osprey
@daring elbow you need to use physics sub-stepping and do your math on sub-steps instead of ticks
Since 4.15 it can be done in BP without custom c++
south ridge
@daring elbow velocity -= velocity*factor*delta_time is what you're looking for. You can recompute "factor" from 0.995 thing easily, but you can also just pick one yourself
x = x - xfactordelta_time is a time-independant way to express x = x*other_factor
fierce tulip
@heavy flicker ofcourse, because red channel gets stored in RGB, and green channel gets stored in the Alpha (or other way around) and blue one gets regenerated in the pixel shader.
so unless you forego DC-compression (and use regular non-normal map focussed compression) you cant really use any of the other channels.
this is as far as my understanding of DC compression goes, and might be a tad off.. but I think i got the gist of it
heavy flicker
Ahh ok thanks for the info

Is there a way you can blend a mesh with the texture on top? so for example is i have some rocks that are slightly under the ground they can take texture properties from the material on the landscape without me having to switch between which texture it is.

Which reddit comment?
sharp summit
😛 Didn't know there were so many people so defensive about Unreal's multithreading performance.
I mean, I'm just repeating the shit I've gleaned from you guys!
cloud cobalt
I'm guessing the guy asks as a developer so most of the MT complaints are kinda not relevant, but still
sharp summit
Yeah, fair enough 😃
cloud cobalt
inb4 the "but you can run async tasks !!!1" folks
sharp summit
Oh well. I'll take the lumps if it means I learn something from it.
And yeah, I kinda did forget about multi-threading for build and lighting stuff.
Cheers @cloud cobalt
south ridge
Isn't UE4 basically suited to two cores
"you can run async tasks" doesn't mean you are running them
cloud cobalt
Yes @twilit gale that's basisally it, though animation, audio, also AI do use other threads
south ridge
Our game is specifically better with more cores since the main gameplay logic is running outside of UE4 and distributes itself on as many cores as you want
cloud cobalt
If you want to actually use 4 cores or more, UE4 isn't capable of it out of the box
south ridge
Plus I wanna make physics multi-core by some engine changes
(multi-world, parallel-calculated, since we have a lot of objects sparely spread out across the big world, they can just run in separate PhysX worlds)
cursive dirge
just... look at this
that's the levels tick function
it seems to explain most of the ue4's game loop
cursive dirge
well tick() kinda belongs on the game thread
south ridge
It's the lack of multithreading high-level ticking interface of some sort that's the issue
cursive dirge
but issue is that those other game systems run on it too
south ridge
You can't easily define certain things to tick automagically on another thread
cloud cobalt
It doesn't, @cursive dirge .
At some point you just need more than one CPU core for game logic
south ridge
Two actors not sharing a data dependency can tick at the same time on two different threads
cloud cobalt
The details of the implementation can vary, it can be a new TickAsync() method that isn't thread safe
The point is, nothing in the game framework does multithreading
south ridge
The engine data could be made completely safe to use in async tick
Only actors depending on other actor data is a real big issue
The main game thread can be simply halted (or something something else that doesn't modify game data like particle systems) so all async ticks read game data with no locking required

i think static means moving with a mesh.. you should be able to vary the 'glow' factor and it be stationary i would believe, but never tested
static means mobility not 'gamma'

plush yew
@daring saffron use pastebin to give us a bit more code
and paste errors as skulltip says
cursive dirge
@daring saffron paste output log when you build that
oh snap
yet another one who crossposts..
apparently he solved this in #cpp already
I always wonder people who do this, like, do they think their issue is so important that they need have different people solving their issues simultaneously on separate channels?
instead one could just ask people to take a look at their issue on the channel where they originally posted and discussion would stay in same place
main cobalt
Sometimes I do, my reason is that I generally keep the lounge or general channel open most of the time, I doubt many people check every new message in every channel, it's just faster to get help posting in multiple places. If I do end up solving it in a different channel tho i'll reply to my message in the other channel or just delete it
I don't think it's too unreasonable especially for an urgent issue or something you've got no idea where to even start with
cursive dirge
yeah but the point is, splitting the discussion will not solve the issue faster
usually the issue solves faster when everyone who try to help are talking in the same space
like @daring saffron here pretty much ignored us on this channel even people tried to help him here as he was busy talking in #cpp / got it solved there
that's just rude IMO, ask for help, bother lots of people and then not to even respond back
sorry if I sound harsh but I see people doing this all the time here and that just wastes resources from everyone and makes people not want to help the guy next time he has issues
worn granite
Clearly communicating that you're asking in multiple channels and directing the main conversation to one channel fixes this issue IMO
If you aren't acknowledging people while you're asking lots of people for help that's pretty rude
main cobalt
True true, ignoring people trying to help is a dick move, at least let ppl know you've found the solution / help elsewhere

No outstanding IO, no nodes in the queue, yet we still have 'PackagesWithNodes' in the graph.
dawn linden
@tender violet Sounds rather like an engine bug to me, maybe try posting as such on AH.
@oblique sorrel Basically you just can't really do that.
oblique sorrel
Oh.
dawn linden
Anyway you can't really change your characters collision shape to solve it.
You could add a separate collider to the weapon, but you'd have to seriously modify the character movement component to prevent rotation based on custom collision tests. Huge job.
oblique sorrel
Well, guess I'm just gonna add waist-high fences to every wall, so that player can't get close enough for the gun to clip.
dawn linden
Better solution, if you really need it, would be to detect and then have the character actually pull back the weapon when there's a wall in front.
But also not trivial, so yeah level design hacks are the easy option.
oblique sorrel
I needed to decrease the capsule size for a damage-related purpose. Player was getting damaged by environmental hazards when standing far away from them.
If I could make OnDamageTaken run from a custom collider, instead of the basic capsule, I could have a large collision capsule and a small damage-collision capsule
But you're probably right, pulling back the gun does seem like a better solution.
dawn linden
I haven't used the damage system. But can't you just shrink all your damage volumes a little instead?
oblique sorrel
That's the thing, OnDamageTaken runs from actor, not component.

eager sparrow
hehehe nuuu, or i could try ubisoft i've not known many equine games made by nintendo lol
foggy patrol
One of the reasons why I personally would avoid Nintendo for such things is because of how Nintendo handles copyright.
echo hill
oh really? how so?
fierce tulip
their lawyers, and they are legally bound to handle it like that.
regardless on how any nintendo employee or ceo thinks of a fan-game
echo hill
oh sure - for clones of their IP that makes sense, sorry i thought we meant games in general 😛
foggy patrol
Well not just a fan-game.
It's also the promoting of their OWN games on YouTube that they shut down etc.

I actually had a question, not sure where to post it. How do I adjust the camera? The standard camera in a new project is verryy.. erhm. How to call it. It has this weird blur on items whenever you move the camera? It feels a bit jaggy.
eager sparrow
it's more to ping ideas etc XD I work in sales so I know how to pitch etc its making sure it makes sense XD
echo hill
@foggy patrol sounds like you mean Motion Blur
foggy patrol
It honestly might be motion blur. Does the new project automatically have it?
eager sparrow
officially dislike UE The text is too hard too read 😛
echo hill
i think if you set the project up as "max settings", then yes
cloud cobalt
Look for motion blur
echo hill
yarp, or if you don't have a postprocess volume in your level, check the project settings - search for Motion Blur and uncheck
foggy patrol
thumbs up Thanks, you are a hero. I figured that the motion blur in a hack&slash rpg is going to be sickening.
eager sparrow
hehehe, eh I'm just happy not to have a backwards typing pc 😛
cloud cobalt
Some level of motion blur can be welcome, but the default settings are hardcore
eager sparrow
I keep thinking it would make a good drinking game lol
I should not be in here on a major sugar crash XD
foggy patrol
OH yeh I imagine that a very soft motion blur will be soothing to the eyes, but the default is.. indeed.. egh. Uncomfortable to say it kindly 😄
cloud cobalt
Basically the project defaults enable all effects and stuff
echo hill
yeah, unless you choose the "scalable 2d/3d" option when you create the project
in which case it goes the other way entirely 😛
foggy patrol
Interesting o:
cloud cobalt
Yeah, though I work for PC so I don't use that 😃
foggy patrol
Yeh my project will also be for PC
cloud cobalt
Basically the "scalable" thing really means "mobile"
Where the rendering pipeline is much less modern
foggy patrol
Mmmhm
echo hill
true true 😃
cloud cobalt
If you're on PC you should probably keep the current setting, design your game the way you want players to see it
Then once the game works you can focus on scalability
eager sparrow
yeah, I just haven't got time for game design right now sadly too busy with new work 😦
eager sparrow
oh?
foggy patrol
That's actually great to know, thank you!
echo hill
yeah, so my PC is really high-spec and my game runs buttery smooth on it - but on my laptop, not so much
but if i dial down the scalability setting to low or medium, its all good 😃

personally i'd recommend anything not a laptop 😛 but depends on your circumstances
eager sparrow
I have the desktop too but thats dead atm untill i can figure out why the hell it blinks lol
I've fixed my laptop 😛 though hehe
cloud cobalt
If you're serious about creating games, a powerful desktop is really a must. You're always going to need more processing power than the people playing your game, and when the time comes to record gameplay videos for example, no amount of performance is going to be too much
foggy patrol
WELL 😂 Basically, I'm going to need a laptop and a desktop. The only place in this house that I can place a desktop is in my work office. I of course can't stay in the work office the entire day, I don't have any privacy AND my mother is not a fan of me being away from the living room a lot. So for that I'd need a laptop.
Aye

A good desktop is cheaper than a good laptop though.

but also the work office etc. thing, so it's still tricky haha
unless you can have like a really powerful PC in the office and remote desktop in with a laptop, but thats getting technical and probably won't work v. well
foggy patrol
Noop. I also need to be able to have it downstairs.
Anyhow I'm looking for a desktop around 1k euro, that should be strong enough for a few years. I can always upgrade it to something higher, but it's a good start I guess.
cloud cobalt
It's quite a good time for that, now that hardware performance has drastically slowed down compared to the previous years
Desktops used to be obsolete in three years
echo hill
yeah, i mean i bought a new PC a year and a half ago, must have been about £800 (not sure what that is in euro, probably not much different :P)
and it'll still run anything i throw at it
foggy patrol
Yeh I heard about that as well! Then again, we've hit the point where we can render photo-realism. So I'm not sure how much higher we can go?
cloud cobalt
I built a machine 3 years ago or someting and the CPU is still very much relevant, with equivalent models costing about the same
The only thing I really need to upgrade are the screens
foggy patrol
This is basically what I have atm. It's in Dutch, but I'd guess that you can figure out what what is.
echo hill
nice... tbh screens these days are not as expensive as they used to be
hmm, okay - not awful but only 4GB ram so might struggle a bit there
i don't know anything about AMD graphics cards so don't know if that one is good or bad 😛
foggy patrol
It's really weak 😂
echo hill
fair play - i only know nvidia 😛 haha

Okay I think that I know how to do it. Get a desk in my room, buy a desktop myself from around 1000 euro. Then get a work laptop for just my art for the work office and so I can walk around in the house. Nods.

Error [SM5] Material.usf(1285,17): error X3000: syntax error: unexpected token '('
Error [SM5] Material.usf(1291,3-6): error X3000: unrecognized identifier 'vec3'
Error [SM5] Material.usf(1291,8-9): error X3000: unrecognized identifier 'rc'
I've tried creating a bunch of inputs for ro, rd, sc, sr, but have not found the right way to get this running. It's a bit of a long-shot, but anyone have a moment to see what this idiot cannot?
tidal elbow
Here's a snapshot of my setup so far.
cursive dirge
@tidal elbow #graphics covers materials
it's literally first thing listed on the channel topic
@tidal elbow all in all, ditch the function, change vec3 to float3
float ndbuffer = dbuffer / sr;
float3 rc = (ro - sc)/sr;
// find intersection with sphere
float b = dot(rd,rc);
float c = dot(rc,rc) - 1.0f;
float h = b*b - c;
// not intersecting
if( h<0.0f ) return 0.0f;
h = sqrt( h );
float t1 = -b - h;
float t2 = -b + h;
// not visible (behind camera or behind ndbuffer)
if( t2<0.0f || t1>ndbuffer ) return 0.0f;
// clip integration segment from camera to ndbuffer
t1 = max( t1, 0.0f );
t2 = min( t2, ndbuffer );
// analytical integration of an inverse squared density
float i1 = -(c*t1 + b*t1*t1 + t1*t1*t1/3.0f);
float i2 = -(c*t2 + b*t2*t2 + t2*t2*t2/3.0f);
return (i2-i1)*(3.0f/4.0f);```like, put that in the custom node
you also left first node blank and you miss dbuffer input
tawdry quail
@tidal elbow thanks for the quote man, that was the case.

Hi, im new kinda new to UE4, i was wondering if there was anyone i could talk to and ask a few dumb questions about things i cant figure out on my own
cursive dirge
if you've tried to solve the things on your own first, you can ask here pretty much anything
but regular searches will usually give you answers too
as basic things get asked a lot in answerhub etc
tidal elbow
@cursive dirge Thanks Dude! That was the general direction I was going, but reformatting to float3 wasn't an obvious thing for me. The rough outline is working, now I just need to figure out how to control all the inputs! Thanks!
shadow edge
Can somone clarify how useing 3rd party content works, i have a few files full of stuff and every time i move them to my content folder they dont show up
tidal elbow
@tawdry quail Glad I could help... and that it wasn't anything too broken;)
cursive dirge
@shadow edge use import
or if you have them in some other ue4 project, use editors migrate tool
technically, just dropping content in content folder should trigger editors import though
like, it should ask if you want to import them
if they are supported type that is
shadow edge
when i do that i get hella errors
heavy flicker
Anyone have any idea why my fps still stays at 30 when i hide everything in my level?
median pumice
Can anyone tell me how to switch the actor who triggers the level streaming volumes? Normally the camera triggers the volumes, but i need my character model to do it
plush yew
@heavy flicker your hardware is low specs?
heavy flicker
Nope, all cinematic
plush yew
joke. but maybe you are doing too much in the Tick event
hiding actors mainly lessens the stress on the GPU
btw, whats your FPS before you hide the actors?
you might have a fps cap as well, though that is at 60fps by default (I think)
heavy flicker
if i hide everything so its pitch black it only goes back to like 90
plush yew
then you have no cap
so whats your fps when you dont hide anything?
you could use the profiler tools
heavy flicker
between 20-50, im gonna try and watch a epic video about that but unless there some commands that can enable a view
Ive read the docs and they dont really have a friendly version or unless im stupid and missing something
plush yew
did you check the tick events?
heavy flicker
no dont think I have
plush yew
the fastest way to see if you are doing too much on the tick events is to increase the tick interval
and look how the performance changes
heavy flicker
Ok cool il give the docs another read and check it out
tidal elbow
Anyone know how I might use a physical sphere in the editor to drive a postProcess blendable material? Basically I would like the sphere's location and radius/scale to feed into a custom node that is doing local color changes.

ok dumb questuon regarding sequencer.. I set up a few clips to play under one Master Sequence, no problem. how do I get it to preview in the viewport? I had it all working the other day when I originally created the sequences and now I can't remember how I did it
patent wren
nope .. that doesnt do it..
shadow edge
then you dont have anything changed
patent wren
i see the timeline in the viewport displaying the name, seq 1, 2, 3 etc as it goes through them .. but the 'video' just doesnt show in the viewport.. i can click placed cameras one by one and view each sequence playing separately
shadow edge
send a screenshot of your sequencer
patent wren
ok one sec
in the viewport i have Cinematic Viewport and Cinematic Preview Enabled
shadow edge
ohh your using it for that
rotund summit
If it doesn't have a NavMesh
patent wren
tearsofdeath - any idea?
dim hemlock
@halcyon marsh there is no 'normal' with ai, it has to be coded for the situation, so by the sound of it you arent instigating its behaviour properly. Or like Snake says, it is not in a navigable area
glossy zenith
i think to get it to show in the viewport, you need to click the camera icon on the right of the left hand column of tracks
@patent wren
patent wren
rbnzdave.. ah that was it! thx
glossy zenith
np. so amazed something i said was useful 😃
i found the sequencer to be a pain in the ass first time i played with it. going to relearn the section of the course again after finishing it.
patent wren
yeah its actually really cool... i took notes on it as I watched the videos ,, but im finding a i missed writing down a few things
glossy zenith
yeah i'm currently trying to adopt the habit of watching the video first, then re-watching while doing. Main issues so far are quick changes they make while i'm looking at my editor. Missing default meshes, missded execution pins, dragging out nodes before setting a type on something expecting a class, so the context is messed up...
classic last night (using bp) was i added in a set node for a var after an add static mesh, but there were 2 add mesh n odes in a row, the first was the one i wanted, the second was an irrelevent one i picked. then got all confused when the vector dist between the 2 was 0, which was of course because the second mesh was stretched between the base and second elements.
patent wren
Honestly it's a just a lot to try and remember ... i use some many different programs and features in each and sometimes its months til I use it again
i make takes notes and screen caps of everything
glossy zenith
yeah i've stopped trying to learn all the softwares and am now just going with unreal. if i need to make assets it'd be either modo or blender, but yeah, leaving unity, godot and gm to rot in their respective corners.
safe rose
@ashen brook You are lucky. At least you got your project to update. I haven't been able to get one of my projects to update to 4.15 from 4.14
Strange message, I even made sure my files/folders were all writeable
UnrealBuildTool Exception: ERROR: Unable to create directory 'C:\Program Files\Epic Games\UE_4.15\Engine\Intermediate\Build\BuildRules\UE4Rules.dll' for intermediate assemblies (Exception: Access to the path 'C:\Program Files\Epic Games\UE_4.15\Engine\Intermediate\Build\BuildRules' is denied.)
gentle ivy
Did you delete your engine intermediates?
gentle ivy
Do that and regen project files
safe rose
You mean the engine build and not the project build?
gentle ivy
well both actually
usually when I see something like this I assume that the intermediates cached something bad
pun intended btw
safe rose
I looked online, definitely seems to be a trend of unhappy devs trying to update anything to 4.15 though
Causes are all over the place though
gentle ivy
4.14 wasn't any nicer either 😦
safe rose
Well, I was going to reinstall 4.15 if it happened on a blank project
gentle ivy
but the improvements can't be argued with.
safe rose
It was interesting to see it going to a new directory
usually it would go under the x86 folder
safe rose
nah
gentle ivy
win32 editor builds 😄
do you have a binary distribution or the source distribution of the engine?
safe rose
both, but this one is launcher build
(school project)
hmm, wonder if this is a VS problem
But yeah, deleting Intermediate in build/project did nothing, going to try blank project real quick
gentle ivy
yeah blank project should work or even a template of anything
if those don't compile then you know something is messed up with your environment/hard drives/etc
safe rose
originally thought it was a perforce issue
gentle ivy
yeah I see that a lot with perforce locking files
but you said you set them to not readonly
safe rose
ya, but I ended up checking everything out
gentle ivy
and the fact you just deleted that entire folder...
cant be readonly unless you got latest again
safe rose
yeah and I am on my admin account on my pc
so, there's only so many things it could be
gentle ivy
you don't check in that folder at all right?
safe rose
man
gentle ivy
you usually shouldn't have an intermediates folder in source control. So it shouldn't even be touched in perforce.
safe rose
the blank project updated like nothing
gentle ivy
have you tried compiling in a vm?
make sure its not the project
kind of a pain to do if you aren't setup for it.
safe rose
Right, not really set up for that. I do need to start figuring that stuff out though. I am a bit behind when it comes to automation stuff
gentle ivy
I'd check and see that if it's easy some how. Just a different environment might tell you a lot.
gentle ivy
Docker?
ashen brook
@safe rose check that your project files aren't set to read-only
safe rose
I know I need to for swarm
ashen brook
first go-to when access denied errors come up
gentle ivy
did you actually go to the file system?
ashen brook
perforce?
safe rose
yeah
ashen brook
allwrite flag on the workspace!
do the occasional reconcile offline work to make sure nothing got missed
safe rose
ah true
gentle ivy
that's the only way to check in source isn't it? reconciling...
ashen brook
nope
gentle ivy
oh does VS have a plugin?
ashen brook
yep!
gentle ivy
hard pass
ashen brook
p4vs
gentle ivy
runs from it.
ashen brook
you can also do it manually if you prefer
check out source folder before work, do work, revert unchanged files, submit
gentle ivy
I might check it out.
ashen brook
or if you collaborate, only check out the files you work with obviously 😉
safe rose
hmm
gentle ivy
Ah with source its easy to merge so I do work, check out > submit/resolve/etc.
and to check out I also reconcile offline work on the source folder.
gentle ivy
ahh yeah that is 100% needed with the UE4 editor.
I always hook up perforce to the editor but never to VS
I feel it gives a nice balance but I will poke the VS plugin and see what its about
overall the perforce locks on source should be ignored though so it might just be annoying.
(unless you don't wanna merge)
dawn linden
I very quickly dumped Perforce VS extension. Buggy as hell, kept locking up VS.

ooph that's not good.

Hi I've dragged content (a sprite) onto the viewport. How do I duplicate an instance of the sprite in the viewport without having to drag another one into it?
Without having to drag one onto it from the content browser
latent shadow
so, with the patching system in unreal, you have to add an extra pak file for each change etc. this can really fill the harddisk space very fast, isn't there a way to just change the existing files or something smilar or merge the extra patch pak file with the original one?
dawn linden
Anyone know how I can generate a smoothly varying 1D noise signal? Basically I just want to perturb some value a little from it's default over time, but the perturbation should change gradually.
dawn linden
Thanks, was just reading a bit about simplex noise.
Is that classed as coherent? It kinda looks like it would probably do what I want.
cloud cobalt
Not sure, but if it works, it works
dawn linden
Yeah I think it will. Pity UE4 only has this built into the material system and not blueprints.
Found a plugin for it, but just gonna go with the sine wave idea for now. Just testing at this point anyway.

Ive noticed that my directional light causes a lot of huge shadow depth posibly giving me low fps. Is there a way to clear them? or how exactly do i optimize
cyan iron
Do you guys know if it is possible to scale a landscape so that the foliage is moving with the surface? 🤔

I doubt that will work @cyan iron . It is better to be pleased with the landscape (including its scale) first before putting any object (including folliage).
cyan iron
Yeah. I guess so. Gotta replant quite alot of trees 😄 Thanks for the respond though.

unborn matrix
How could I have a blueprint cast to all types of blueprints?
For example: if I have a bad guy shoot out a bunch of goo, it should slow down all enemies within the goo.
The way I'm doing it now seems.... incorrect even if it works.
what I'm doing is having a bunch of IF statements checking what type of character my player is using, then casting to them.

How do I get ahold of UE4 4.16 preview? I have access to the github source code but cant find any branch that is called 4.16 or is it the master branch I should check out?
cloud cobalt
Probably the master rbanch at this point, yes
Names branches occur once releases are in progress
There is no 4.16 preview yet, so what you really want is the current WIP of the engine, some of which will become 4.16
shy zodiac
Ok. Thanks @cloud cobalt. Only used the launcher before but wanted to test some things.
cloud cobalt
Yeah I do hope you're not actively using it for development 😃
There is also the "promoted" branch which is supposed to be used internally at Epic
Less hardcore than master
shy zodiac
No no. For my "real" work I use 4.15 but needed a break from everyday work and wanted to play around a little.
cursive dirge
it's master only atm
cloud cobalt
I have tried working with previews once, will never do it again
We have a good process for updating the game now
(work on master, prepare migration on a branch, merge when version is released and no blocking bugs)
worn merlin
Does anyone know if there's a padding thing in a UMG Widget
Ive got a white square on the top right
UMG size is 1920 x 1080 too
In game it's shifted over to the left?
kindred viper
where is your anchor set to?
kindred viper
it looks approximately half the width across to the left.
it may be the DPI scaling or the viewport size not actually being 1080 but the fact it looks half the width across makes me think its just an anchor issue. Have you tried other anchors? Like top right or center?
oh sorry u said you did
kindred viper
could be. it should be 1.0 at 1080p usually
if you check the DPI curve to make sure though, as it could be that too
kindred viper
yeah it looks default
worn merlin
wonder why its showing DPI Scale 2.0 when it says there Resolution: 1080 Scale 1:0
kindred viper
that means if you put your UMG setting to 1080, it should say DPI Scale 1.0
worn merlin
Still shifted over to the left 😦

I think its just PIE that it's fucked up
yes it is

honestly with my recent experiences, I think a lot of stuff is messed up with DPI scaling

Hi everyone, simple first question :
I have a 4 floor buidling, I can teleport my player into each floor through a teleporter. Should I create a new level (map) for each floor, or should I create these floors in the same map? knowing that each floor has stuff in it, like furnitures, but nothing in movement, everything is static

I've been using VSTS, it's cheap and has no cap on storage for private repos, but all depends if you want to use Git. Until LFS 2.0 is supported by more things, file locking from perforce seems rather attractive.

@brittle gulch How big are the "floors"?
Im assuming your concerned about performance?
brittle gulch
yes I'm talking about perf. The floors are about 600m², they are splitted in a few appartment but only one per floor is really detailled with furniture and stuff. The other one are empty

If your worried about performance then Stream them in as sublevels when you need them.

So I'm trying to make a spline road tool, but for some reason raycasts ignore it even though I have set the collision in the blueprint to "Collision Enabled (Query and Physics)" Am I missing something?
As an example I've used a basic cube as the mesh. It shows up when viewing player collision but not visibility collision.
I've been trying to figure out why. Anybody have any clues?
It says here raycasts should work with it.

Hey everyone! How's 4.15 working for you who have updated? I read about some problems with materials and tone mapper
cloud cobalt
It's working fine, and it changed some stuff for materials and tone mapper
And Blueprints
There was basically a lot of hate because Epic didn't keep rendering the same
fierce tulip
it could use some finetuning, and perhaps some additional material options, but its fine imho.
plush yew
thanx guys
Our game is about 2 months from release, so I'm most worried about stuff that would need a lot of adjusting
like going through all teh materials or something
spare topaz
so, how does replication work? I'm trying to replicate a simple character components rotation. Only thing is that no matter how I try to replicate its rotation only listen server client's rotation is visible to anyone
fierce tulip
you can reset the tonemapper to the old one, but you might need to tweak some bloom etc as well.
cloud cobalt
Also the old one is going away
@plush yew Simply put, don't update if you're close to release
plush yew
good advice
but I'm on the edge
if I update now, we still got time
if I don't, I certainly won't update before release
and if a problem arises, Epic won't provide much support for an outdated version
cloud cobalt
They won't provide much support for any version to be honest
New versions have bugs too, and 4.15 isn't fully stabilized yet
If you haven't any known bug in 4.14 i'd stay there

halcyon marsh
hello everyone i need infromation about collision if anyone can help me please
the OnComponentHit Event works only if the component is hitting by something or also when it's hit something
plush yew
both
shell jetty
17 would be pure awesome
plush yew
ant the other object does?
halcyon marsh
collision mesh
it's work fine with overlap event but not with hit event
it is attach to my player i do animation attack to test the collision to a wall
plush yew
I think you shouldnt use both overlap and hit events
plush yew
but what is this sword hitting?
halcyon marsh
a box
plush yew
does that box have block set to sword collision?
plush yew
double check
halcyon marsh
yes ^^
halcyon marsh
not all
because it will block the player x)
oh wait
i will see if it's collide with the player
plush yew
😃
halcyon marsh
it works with the player
halcyon marsh
the box is blocking all
plush yew
perhaps wrong object type
or bad collision
are you hiting the mesh
or a box collision?
halcyon marsh
and also the sword is blocking all (EXCEPT sword and pawn)
mesh
a Cube from the Modes "Base"
but overlap with a sword is good
because hit will generate permanently the event
i just wanted to know why this not work ^^
vale osprey
well, collision enabled is set to Query Only...
halcyon marsh
what does mean ?
vale osprey
Queries are traces, not collisions, change it to query and collision
vale osprey
on your screenshot it is set to Query Only
halcyon marsh
i changed by the time
vale osprey
there are several things which need to happen to start receiving collision events:
- Collision mesh on both bodies that collide
- Collision Enabled: Query and Physics on both bodies
- Both bodies need to block the each other's channels -> sword should block box channel and box should block sword channel. "BlockAllDynamic" doesn't always work especially when you have custom channels
- Generate Collision Events should be On on receiving body
- Receving of event needs some very simple debugging like print string
halcyon marsh
yes by like i said the overlap works find ^^
i have a question @vale osprey
i want to spawn particle at impact location
i use this
but i dont know if it is the right way
vale osprey
Overlap is not a collision its irrelevant if it works or not
ther eis no Impact Point in overlap event, that values is zero
vale osprey
at which location?
vale osprey
you need Collision event for this
halcyon marsh
overlap doesnt work ?
vale osprey
overlap just says if two volumes intersect, it doesn't say where they intersect
halcyon marsh
oh man ...
i stay all night learning on this
for nothing
What is the goal of the Sweap Result ?
vale osprey
you can do a Sweep Test when you move an object, to check if something will be in its way
halcyon marsh
now the hit event doesnt work
and it is the only one
that can give me the hit location
vale osprey
have you changed settings on the box?
halcyon marsh
it's working fine with the character
when he run
i did both @vale osprey
the sword is a child actor of my character BP
i attach it to a socket
vale osprey
no idea how it is suppose to work in such configuration

It's been a few years since I worked on UE4 so I may be missing something obvious but if I want to import a 3D model and then control that 3D model with some other program that's linked with Unreal, do I still need to import the model via FBX?
fallow cliff
@eternal osprey you'll have to save the model each time you change it in the other program. UE4 has an option to detect those changes and auto-reimport the file for you, but in general, yes, you have to reimport the model
we're currently working on integrating certain modelling programs more tightly, so that updates to a model in the program will be reflected in UE4 in real-time
but that's still some ways out
fierce tulip
i think he means make it animate alongside mocap, or hand gestures, tracking, etc
fallow cliff
ah, maybe i misunderstood then
fierce tulip
maybe i did :p
eternal osprey
actually to be specific, I want to import a URDF file which is a format used by robotic simulators and then control that imported robot with a linked library
so the issue is I'm not sure if I should be importing as fbx
I will be making a program that will parse the URDF file but then I'm not sure if I should be converting to an fbx since it can't simply be a static mesh, I will need to be able to control the joints and stuff via the linked library
I think for importing a 3D model into unreal, fbx is the only option isn't it?
vale osprey
@eternal osprey correct. You could make a custom importer that will create both static meshes and wire some logic described in URDF, but this is not a one day task
The easier option is to import your robot either as a skeletal mesh with all parts in one rig or as separate meshes for separate parts
cloud cobalt
@fallow cliff Is Blender one of those ? 😃
vale osprey
Then build a set of components or actors that can communicate with external device and update position of static meshes or bones in skeletal mesh

@cloud cobalt not at this time, no, but i'm sure someone in the community will add support for Blender at some point. first we gotta get the basics in place on the Editor side

so I want to select 100 static meshes, set the accuracy and max hull verts and let it generate collision for those 100 static meshes

hi, if I have a .pak file can I convert it to .exe? how? specifically I am talking about BarcelonaPavilion-WindowsNoEditor.pak
also I am looking for some executables with realistic rendering
can you please share link with me that are made with ue4?
fallow cliff
a pak file is really just a zipped version of a game's /Content directory
and possibly also Config and a few other things
you'll need the game's executable and binary files to use it
if the pak was created with just plain Unreal Editor, you could possibly just drop it into a project directory
i think the -pak command line parameter specifies which pak file to use. i don't recall the syntax and any other parameters that may be required off the top of my head

@whole quarry Setting the cube to Complex as Simple didn't fix it
I don't know if setting the collision on the mesh that I'm using even changes anything since I have to use a Set Collision Enabled node in the spline blueprint

Why is my texture resolution so low when I start the game compared to when I am in the editor...where do I change this setting?

anybody can help me with the model viewer in unreal engine :C
it is to showcase some 3D scenes (no playerbp's involved just many cameras and a 3Dscene with baked textures)

Does anyone know if it's possible to change the default black void of empty space to a different color? Maybe via the SkyLight or a PostProcessVolume setting that I don't know about yet?

@unreal sonnet Add an Skybox??

Anyone know why on iOS, i can play my develop game, but shipping one is not working?

@weary basalt Yeah I was secretly hoping that there was an easier way without having to go through a tutorial or two of learning how to make skyboxes.

There is an basic one that comes with the engine mate.

unreal sonnet
@weary basalt I tried using some of the engine ones (Daylight, DaylightAmbientCubeMap, and DefaultCubemap) but they all tint everything either blue or orange. Was hoping to find a basic white light one. Maybe I should keep looking through them all.

Search for the SkySphere blueprint actor.
Either that or just simply add an Atmosphereic Fog actor to your level.

Just regular BP code

Can you help me with BP instead BT
BT is complex I find it to be not a user friendly.

Its a much better system to use than regular BP code for AI. It can be a little confusing at first.
I would help you but im in bed at the moment on my phone lol
Maybe tomorrow if your still around
wild cloud
Can you send me pic of your sample BP? If you have some screen shots?
weary basalt
Plenty of others here that maybe able to help you

They are not responding for my help.

I could send you the project later if you like

Ok thanks. @weary basalt 🤗

No worries. Im off to sleep now. Cya later

Protip for everyone: use "show collision" in the console when you're pulling your hair out over a bug. It saved me a huge headache just now.

While trying to minimize my package for the game jam, I unchecked the plugin browser. Is there any way to re-enable it? Because one of the plugins I disabled apparently was necessary x_x

@jfaw skyboxes aren't really all that high tech, they're just spheres with inverted faces. If you're feeling really lazy and you just want a white skybox. go to Basic>Sphere drag that into scene
then create a new material
give it those settings - two sided
and base color of 1
scale up sphere to 9000, 9000, 9000
done

Protip: go to Edit > Editor Preferences > General > Keyboard Shortcuts > Blueprint Editor. Also the Graph Editor section. I wish I had reviewed or assigned these things earlier!
Binding a button to "collapse to function" as well as for "go to definition" is beyond useful!

so, how does unreals enum bitmask stuff work? from the name one would think the enum would give 1,2,4,8 instead of 0,1,2,3
spare topaz
wouldn't combining 2nd and 3rd value end up same as 4th value with how unreals bp enum bitmask stuff gives the values?
I'd rather not start writing c++ just because blueprints lack bitwise shifting operators
so I'm trying to figure out if I understand everything wrong or is Unreals bitmask enums just fucked up when looping through

first error there is "ERROR: No 32-bit compiler toolchain found in"

anyone know if there's a way to pass parameters into a child actor to be used in the construction script?
at runtime that would be like Expose on Spawn
basically I'm trying to add static components, which only seems to work during construction, but I need to adjust the parameters of the blueprint instance before the construction script runs
oh, cool
works via construct object I think

Would anyone know how to have the groups of the world outliner being folded by default ?
When I edit a scene, I have to scroll trough dozens of opened folders and objects before finding what i'm searching for ( and yes I'm aware of the search textbox )
ashen brook
fyi, construct object doesn't work with actor classes
sigh
I wish there was a way to preinitialize child actor instances
lime cobalt
@ashen brook Yes you gotta use spawn actor
and It's not possible to create actors using construction script which is Imo, sad
floral heart
Then the editor would have to keep track of actors spawned and remove them on update.
lime cobalt
TArray<AActor*> LeActors; // le keep track
hashtag technology, computer entertainment etc
floral heart
It does allow you to draw debug shapes. Which is hilarious because it doesn't keep track of them. Duration 0 == debug lines forever.
Actually, I don't think it uses the duration either.
So no matter the duration, debug lines until you restart.
lime cobalt
Too bad because construction script could be a powerful thing
hopes the capabilities of construction script would be extended
ashen brook
you can flush debug lines
which I pretty much default to doing in anything I use them in
unreal sonnet
@halcyon marsh I had that error as well with my game jam submission yesterday. Turns out it was because I deleted the Binaries folder on accident and/or because I disabled too many plugins. To get the Binaries folder back you need to build the project in VisualStudio or whatever, and to get the plugins re-enabled you need to go into the plugins folder of your project and re-enable all the things that are listed in there.
halcyon marsh
@unreal sonnet the problem was solved thank you anyway I just had to install c++ in visual studio

[Copy] Volumetric Fog using a volume texture mapped to the camera frustum
* Volumetric fog can be enabled on an Exponential Height Fog component with additional controls
* Lights have a VolumetricScatteringIntensity
* New cvars r.VolumetricFog, r.VolumetricFog.GridPixelSize, r.VolumetricFog.GridSizeZ, r.VolumetricFog.DepthDistributionScale
* Lighting features supported:
* Directional light with CSM and a light function
* Point / spot lights without shadows / light functions / IES profiles
* Skylight with occlusion from distance fields
* Analytical height fog covers the view range past where the volumetric fog ends
* Temporal reprojection is used on the volumetric fog scattering and extinction to achieve stability
* Translucency integrates properly into volumetric fog
* Height fog StartDistance is not supported by volumetric fog and should be set to 0.

Hey everyone. Does anyone know if its possible to make external content libraries for UE4? We are slowly accumulating lots of custom made materials that we use across different projects, and its very hard to keep them updated. is it possible to make a "library" project that my other projects can refer to
cursive dirge
That sounds risky
@Zpanzer all your projects would need to use the same engine version...
I just keep separate asset projects for sound and other assets, and just migrate from them on demand
glacial belfry
Well, its a pretty standard way of doing stuff in the rest of the DCC atmosphere 😛 Its just not a very good pipeline to have to manual copy stuff between lots of projects
fierce tulip
easiest i found so far is actually store those inside the engine content folder instead of project content folder.
that way you only need to copy/paste once

Currently number one on the list of my most hated bugs.. I have a character BP, with a skeletal mesh. And a child of that character BP, that uses the same mesh and doesnt change it in any way... And each time I open the editor, the mesh of the child gets cleared to nothing. I set it back, save, restart, same thing.
Anyone else had that problem?
or similar
this is not about settings per instance (another huge pain). its about default properites of a class

hey what do you suggest to use to store different languages in game? data tables? or something in C++?
livid haven
store different languages
?
We talking localization/internationalization? You should definitely be using FText and the sort for that
heady root
I want create system to change language in game and Im not sure what is the best way to store data
livid haven
You shouldn't - it's already been done. 😃
Probably horribly out of date documentation, but the concepts are still relevant
heady root
localization dashboard you ment?
livid haven
The localization dashboard is just a graphical interface to handling the localization data pipeline.
You should be using FText, be it in blueprints, in code, or using, I think, the new text table feature (not too familiar with that).
heady root
ok i didnt know something like this exist..thanks 😛

I don't know that you can do that out of the box. I never added such functionality, but I wouldn't be surprised if it was added later.

Hey 😃 Any reaon imported FBX Meshes with good UV-Mapping on channels 0 and 1 still get interpreted as overlapping lightmap UVs? They look fine in the UV View of the asset editor. Both channels...
fierce tulip
means that they arent as good as you think they are.
they cannot overlap, need to be inside 0-1 space, and cannot be mirrored
(only for ulightmap uv)
plush yew
The source of the UVs are CAD datasets which have then be packed to 0-1 using 3ds max. They are nearly stretch free, meaningful seams etc. They may not be optimal regarding distribution and use of UF space but they are 100% definitely not overlapping and have pretty large distance to eachother so no bleeding happens.

If you mean rendering to the GBuffer from two cameras - nooop

there needs to be a proper way though, render to texture crap and that stuff is crap, outdated, and inefficient
