@gleaming shore Could you use dynamic material instances? Just have a vector parameter linked to the basecolor and use the setvectorparameter node in the bp.

How can I change which character a map uses?

If they implemented it properly, a projectile with 0 radius is basically a bunch of line traces anyway.
gleaming shore
https://i.gyazo.com/229c51f6f784cd2ab9d864bda6844e44.png is this because i installed a plugin?
fair violet
@plush yew if multiplayer, trace for almost all guns for sure. Just makes it easier to implement. I like how Fortnite has projectiles for sniper bullets though as they are slow firing and take more skill
plush yew
mhm
weary basalt
I prefer Raytraced “bullets”
weary basalt
Way more responsive and feels better gameplay wise in my opinion. If its an close quarters game i cant imagine what pros Projectiles would have over traced bullets
floral heart
It's also a question of distance. For small games like counterstrike, a projectile traveling at real speed will probably hit in less than a single frame anyway. Ergo, a projectile with 0 radius is a bunch of line traces anyway.
For games with more scale, the physical presence of a weapon becomes more important. Nothing in real life is instantaneous. Though, relativistic rendering probably won't be a commonplace thing while we still have eyes.
fair violet
And network efficiency- good luck replicating hundreds of projectiles on a fast firing machine gun
Ray traced bullets are definitely a good option
floral heart
If they're dumb projectiles, client-side prediction is likely good enough, since you already know where the projectile will be going from the moment you spawn it.
Also, are you really going to have ray traced rockets or missiles?
fair violet
Rockets or missiles are great candidates for projectiles
They won’t be rapidly fired and travel slowly
So they can fit in the budget
An LMG however.. different story
weary basalt
Anything that actually fires an projectile like rockets would not be raytraced
floral heart
Tell it to MW:O. For some reason they implemented missiles that can be fired a hundred at a time, and because they can lock on they aren't dumb and seem to be predicted. The game is stuck at 24 players and can't support any more in a match.
weary basalt
Its not like it cant be done. Its just expensive
fair violet
Yeah it’s just very inefficient
Depends on the game though
If it’s a key mechanic then sure that’s fine
Feels nicer to be as lean as possible though
floral heart
The question of "do you prefer projectile based or line traced" is a strange question. It implies your game is being designed around a single function.
weary basalt
Yeah i would make that decision based on gameplay factors not personal preference
But personally i do like raytraced weapons.
floral heart
Personally I could go for sweep weapons. Flamethrowers, I needz them.

worn granite
I mean you could read the wiki - I'd lean towards just referencing stuff though.
cursive dirge
if you know c++ already, just read docs c++ intro stuff
coarse cradle

its just hard to understand sometimes
read up a tutorial on how to cel shade
but rather than just to copy the tutorial I wanna understand how it works
so I reference the docs/wiki a lot but still get stuck on somethign
*something

coarse cradle
I mean

this is gonna be just one that might sound stupid

it's poorly documented

watching a ue4 livestream while searching up the stuff seeing if I can understand it
cursive dirge
lerp = linear interpolation
it doesn't actually have anything to do with time
it's super simple
coarse cradle
on the doc it says when alpha = 0 then (A=100%, B=0) ice versa
so im assuming if lerp was 0.5 (A=50%, B=50%)?
*if Alpha was 0.5
cursive dirge
yup
cursive dirge
ummm no
you interpolate between A and B
you don't change them
if A == B, you get same value
regardless of alpha
cursive dirge
coarse cradle
think I have a basic understanding of what that is...
i mean its a shitty draawing but bear with me
lets say 10 is a and b is 20
ignore that part at the bottom lol
gleaming shore
how do i make custom events fire, i totally forgot
coarse cradle
anyways depending on the alpha value does LERP select the number on the number line between 10 and 20?
so if lerp was 0.5 it would be 15?
and if lerp was 0.25 it would probably choose 12.5?
silver crown
Yeah
cursive dirge
yes

just look at that code
if you don't know much math, code should be self explanotary

Im not sure how to use the reference is what I mean
weary basalt
Call DestroyActor?
gleaming shore
Just tried it, the target pin wont for destory actor wont connect to spawned sound
weary basalt
gleaming shore
weary basalt
Drag from the Sound node and search for Destroy
there will be an DestroyComponent node
But you will need to save that Sound Object as an variable and access it from the Variable. You shouldnt cross execution paths like your attempting to do.
gleaming shore
What could I use to set a variable like "is playing" from the spawn sound?
coarse cradle
Probably a pretty basic question but
How does unreal pull ambient occlusion (red channel) metallic parts (green channel) and the non metallic parts (blue channel) from just that 1 texture sample on the left picture?
floral heart
Are you expecting it could only sample one channel at a time?
coarse cradle
wdym?
floral heart
The channels are already separate. It doesn't need any extra effort to get to them.
That fourth row seems to be a strange combination of them.
coarse cradle
said it was a whole object mask
I think I understand how it works now tho
was looking at the 4 channels (RGB) and I thought it literally meant the color... but it really had no relation and was just uder defined channels
*user
floral heart
It is the color, though. A color is 3 channels, red green and blue, and the 4th channel is alpha, which is a bit of a wildcard.
For humans, anyway. Other animals can see color differently.
coarse cradle
well thats true
but I got confused thinking that the nodes were some how pulling out like red color data from the texture sample
ahhh I get it completely now
floral heart
Are you looking at the material in startercontent?
coarse cradle
yeah
the chair
trynna see if I can undertsand how the material was defined
found a good explanation online tho
kinda still stuck on why lerp is being used tho
I know its function just hard to see why its being used in that case
\
then the alpha is connected to the blue channel which is the non metallic and control of color of non metallic objects
floral heart
In short, there's a base layer and a metal layer.
Wherever there's green, the base layer lerps to the metal layer. Full green = fully metal.
In other words, the green is used as a layer mask.
coarse cradle
alright
but then again, whats happening here?
its trying to define a metallic value
im assuming any green that can be extracted from the texture sample is going to be metalic>
?
when I say green I mean any color on there that has the combination of green aswell
im assuming that depending on the intensity of the mixture of green it also adds the metallic effect to that spot on the mesh?
floral heart
'Metallic' is just an arbitrary value that is later used in lighting calculations to determine what kind of shine the surface has. High metallic means the shine will look more like raw metal, low metallic means the shine will look more like smooth plastic.
The amount of metallicity is one part of what the green is used to mask.
coarse cradle
makes a lot more sense now
so in that pic I posted depending on mixture of green in the specified area it would choose a value between 0 and 1 to make that area of the mesh metallic?
vale osprey
in general yes, you just frase it a bit weird
it doesn't "choose" anything
texture is 4 arrays of numbers, in material you define which array you want to use for something like metalic for example
coarse cradle
mhm
vale osprey
let's say you load just a black and white texture without alpha
its doesn't have color but at the same time it can be any color or metallic or roughtness
because it's nothning more than a set of numbers
in material, when you connect nodes, you are saying "I want this data to flow into this function"
so you can read numbers from green/red/blue/alpha channel and wire them to something that is going to transform them in some way or something will use it as a final result for a color/alpha/metallic and etc
vale osprey
yes, nothing stops you from swapping color channels in material
you can swap Red and Blue completely, or you swap them to an ammount of Green at the same texel
all because, textures are not "paintings" but arrays of numbers, the same with final color or material - it's just a function that takes X and transforms it into Y
vale osprey
@floral heart funnily enough I coudn't find in google a simple explanation with illustration of what texture is 😄
floral heart
I was hoping it didn't need explanation. :x
coarse cradle
oh just 1 more question if youre still here
how would I create a texture mask?
from my understanding I paint everything I want white and export it as R G or B, or a mixture with other images that I painted
vale osprey
correct
in most of the image editing packages like Photoshop, you can edit individual channels - RGBA
so you can place one mask into R another on G and etc. Or you have a texture for material without transparency, then you can use A channel for mask
coarse cradle
I see
but you could also just apply a texture over the uv
why did unreal do this method instead of just applying a texture over the unwrap
is it so they can also customize the metallic and non metallic properties through the use of RGB?
floral heart
Sort of. It goes back to the layers I tried badly to explain.
floral heart
In Unreal's PBR workflow, the appearance of something is typically defined by its albedo(base color), metallicity, specularity, and roughness. A texture is usually only enough to define the basecolor. However, if you use it as a mask, then you have three or four masks that can define different sets of albedo/metallic/specular/roughness, layers. Which works if you don't mind that each layer is a flat color.
smoky pilot
What is the difference between roughness and specular? Aren't they both the same thing?
Roughness is the new specular, isn't it?
fair violet
Roughness is how shiny or rough a material is, specular in UE4 (in my own words) is almost like a scale for how bright the ambient reflections and overall sheen of a mesh is displayed- more apparent at higher Roughness values. Usually 0.5 which is the default is fine but in many cases, you want to play with it to provide a more natural response in a lighting scenario (often you get assets that have an ugly almost coating of white sheen that doesn’t look realistic in comparison to the same asset using a lower specular value) Basically it isn’t PBR accurate and it is sometimes useful to tweak artistically
vale osprey
One of the differences is that roughness effect diffuse color too, along side the specular
I’m not even sure if there is split between diffuse and specular anymore
Less rough objects will reflect light in a tighter cone and fully rough will reflect in 180 degrees making it look fully diffuse
fair violet
There’s a test I did recently- default spec on the left, 0 spec on the right
It definitely changes the perceived lighting response drastically
high oriole
Can anyone tell me why when I'm exporting from maya, my mesh imported to unreal shows up way off center?
It's way over there by the yellow highlight
fair violet
Did you export your mesh at the origin in Maya?
high oriole
it has to be centered in maya?
fair violet
Yep that’s where the pivot in UE4 will be
high oriole
I guess that explains it. I thought that.
I'm trying to model some realistic grass lol
fair violet
Gotta get those curves in!
vale osprey
@fair violet you mean spec as specular input? it has some meaning for sss materials, outside of those I don't what exactly it does
fair violet
Yep specular input
That’s what it does as shown in the screenshot- the scale of that “sheen”
Roughness is 1 in both cases
high oriole
the curves will be done via box lattice later on
I haven't set any of the specular up yet. I'm do all the texturing in unreal engine or substance I'm new to texturing
floral heart
I think specular input just scales up and down. Ordinarily you don't mess with it, but it can be used to mute/occlude specular reflections, as you might see on some more organic surfaces.
high oriole
Right now my main focus is just getting it to look right for the most part, I have a pic of some previous made grass in unreal already but there's no normal maps or anything special
high oriole
roughness 0.8 specular 0.2
is the setting
right now it's not setup I just have a lambert on it
I had issues with the scale and size of it so that's what i'm tackling to get the size perfect
fair violet
If you really want to make the grass yourself, might be good to reference some scans to get the right proportions / shapes
fair violet
Nice!!
high oriole
the ones on the far right are handdrawn via tablet but they dont look right in unreal
they get all pixelated
and too skinny
fair violet
You are using this texture on the actual assets or just as a ref sheet?
high oriole
Well, I'm gonna crop the blades out to make a single texture full of the grass blade patterns just to have differentiation between blades but yea
then I apply it to the blades and basically warp it like grass blade then bake the texture to images
throw them on billboards and in to unreal
I thought about just grabbing some grass off the grow and throwing it in my scanner and see how that works out lol
fair violet
Yeah doing that and modeling some highpoly broad normals to bake down into an atlas would work fine
Then you could assemble patches or instead bake highpoly patches down to a billboard atlas
high oriole
thats the plan
once I'm done if I get some really good results I'll put em in the unreal marketplace
high oriole
I'm close, on the right track at least. It looks right I just need to sort the scale in maya abit

Hey was curious if someone could help me out with something
I'm working on a HUB like online game where players can meet and chat and do other fun activities. One feature im having an issue with is clothing products. So when a player uses in game money to buy cloths from another player who has a job at say a clothing store how can i go about making it where the Shirt, Pants etc... will connect to his Rig and move just like the base model would have done.

Not sure which sub chat I should put this in, but does anyone know what "Composition PreLighting" relates to when trying to profile using stat GPU?

Found out what my performance hit was... I forgot to delete a Scene Capture Cube that was updating every frame on a high resolution
rose sequoia
Anyone know what could be causing this to happen? With the close-up being as the material is intended to look, but the zoomed out version is all noisy and dissolved https://cdn.discordapp.com/attachments/314073823559548930/402167448318771211/unknown.png
Don't have any LODs setup, tried changing mip-map settings, as well as creating a plain blank new white material and placing it on an oval. Zooming out resulted in basically the same thing https://cdn.discordapp.com/attachments/314073823559548930/402183855722725377/unknown.png (The lighting was built in previous tests so I don't think it's a problem with that)

Hey guys
I'm having a problem retargeting
The preview window meshes look different
but on the scene
they're the same size
(the scene models don't have custom scaling)
honest rune
whats with the platform on the feet of the mesh with the weird thinsg around the head?
that is weird though
I'd assume the true scale of the imported mesh is actually that much bigger by the looks of it
thorn cradle
The platform on the feet is just a quad to show the position of the root bone
And, honestly when I imported both models
I had to use custom import scaling for one
so, maybe that's the problem ?
honest rune
most likely
I wouldnt do that if the models shar the same skeleton either
I don't know how it would be have in animations by scaling that way. normally you want your scale (and normals etc) recalculated in the dcc software before exporting
heady bridge
Hi, when I start my game in Standalone, it opens on the wrong monitor, not the one set as my main, is there any settings in the engine to fix it?
honest rune
either clear your systems saved window positions or while standalone is open, drag the window to the other screen and then close it. system should remember thats where you positioned it last
heady bridge
Dragging it over to the other monitor and closing it there didn't work, I tried with the X and the command quit
honest rune
is it opening on the same screen that the editor is open on? (or that the editor opened on when you first launched the editor)
heady bridge
The editor opens on my right monitor and same with NEw Editor PIE, the only window that automatically goes to the left is the standalone. Even when I play any fullscreen game it opens up on my right, it's just that for some reason

i have a question.. is there a node that triggerbox will gone when i step another triggerbox ?

You can do a lot of stuff with Temporal Dither, barely anything I use nowadays has "real" transparency.

all that happens is it opens up a window alongside the project window except I can't open the window and it shows it as a black bar

have you checked the logs?
cursive dirge
sure there are
lime cobalt
UE4 is building shaders the first time it's installed
azure shore
I double click an asset and nothing opens
It was working fine before!!!
I've been using it a while!
lime cobalt
ok it's all types of assets
whole sonnet
@azure shore Did you try to verify UE4 to make sure its not having any issues missing files or anything?
cursive dirge
bit late but this is also one reason why people use version control, to be able to roll back if things go wrong
azure shore
idk it was working fine earlier today
I was planning on doing that but I've hardly even made much yet
lime cobalt
@azure shore did you update unreal or made construction script blueprints ?
azure shore
no...
lime cobalt
are you on 4.18 ?
lime cobalt
with the source built version of UE4, it'd be possible to see what's hapenning ....
pausing the editor and see what's in the call stack...
@azure shore also, can you re-describe your problem entirely ? once you openned your UE4 project, you cannot open any assets ?
azure shore
I'll send a screenshot in a sec
lime cobalt
^ that's nice to know, the logs
azure shore
where are they then?
cursive dirge
users / <username> /appdata/local/unrealengine/saved/logs I think
azure shore
ok...
cursive dirge
could be more somewhere else, can't remember
plush yew
I can see the assets at windows explorer , but at unreal engine there is no assets.
azure shore
I get this
and if I click it nothing happens
it's not just a 5 hour loading time is it?
honest rune
for an anim frame, no
azure shore
same thing happens with any asset
lime cobalt
@azure shore it's an anim file ? does it happens with every type of file you try to open ?
azure shore
yeah
honest rune
sounds like your pc is struggling
azure shore
maybe
lime cobalt
i'd check the appdata logs indeed
azure shore
but it was fine this morning
lime cobalt
@azure shore how much is your project folder ? 10gb ? 20gb ?
personally, I'd do a backup copy of it
azure shore
the project file is 1kb
lime cobalt
no, the project folder 😄
honest rune
lol
lime cobalt
with all the maps, textures etc
azure shore
it doesnt say... its a folder...
honest rune
rightclikc on folder, select properties
azure shore
I can run the project as normal
I tried other projects including the default project and still the same thing

you did try closing and re-opening project yeah?
plush yew
I can see the assets at windows explorer , but at unreal engine there is no assets.
lime cobalt
@azure shore did you check these logs tho ?
azure shore
I can't find them!
honest rune
any luck if reloading the project?
lime cobalt
@azure shore can you locate your "users" folder ?
@azure shore Indeed, reloading the project needs to be tried too
@azure shore because AppData is a hidden folder, so once you're in C:/Users/ (yourName)
check the folder window, you'll see a text bar containing a text line with C:/Users/ (yourName) written on it
add " /AppData/ " to this bar
honest rune
or %AppData% right into explorer
lime cobalt
oh yes, I didn't know this ^, much easier
honest rune
ancient chinese secret :p
lime cobalt
for me, the folder is in AppData/Local/UnrealEngine/4.16
@azure shore can you see how to find these logs ?
using @honest rune awesome method
safe rose
Hmmmmmmmm... so someone messed up a setting somewhere in a project I'm working on, instead of rolling back, I'd like to try to figure out wtf could they have done...https://i.gyazo.com/2362be27e77d8c7a97581f7093008df4.gif
That's on a blank new map
azure shore
and yes like I said I've restarted the project like 50 times, restarted computer, and reinstalled the whole ue
lime cobalt
@safe rose wrong friction/physics settings ?
@azure shore if you search into /Unreal Engine/4.18/ can you see any logs ?
lime cobalt
also, I think you can find additional infos in the Project folder
@safe rose okies then

I just looked at teh diff in project settings
lime cobalt

Someone dun fucked up
lime cobalt
@safe rose what commit system do you use tho ? Github ? SVN ?

very odd, I got send 4.18.2 ueassets, but they dont appear in the content browser at all
frosty bloom
@fierce tulip Did you migrate or import them into the content browser? Sometimes when assets is copied from folder directly to content folder it requires a restart of the project for them to show up. (I have had cases were I had to delete said assets and re import them too)
plush yew
Does anybody know how to cach images locally in Blueprints. We use Download Image to get the images, but there is no caching option. Any ideas?

define 'cache locally'?

@frosty bloom thats not it, I know how to do that and been doing it for many years.
they just dont appear.

@fierce tulip Sure it's 4.18 and not custom source build?

though i highly doubt it
oh god rofl, for some reason it starts ue4 with last used filters
never did that before on new projects

well, if a question is just a very simple google search away and you are asking a very basic question.. you can kinda expect that.
I'd suggest to google "ue4 blueprint scale actor over period"

@light thunder Are the buildings in BP's?

does anyone know any tutorial for importing static mesh as skeletal mesh?
fierce tulip
fierce tulip
"At the moment, we have a ticket in for this with UE-13425, which is currently backlogged. There is a limitation with using instanced static meshes for culling since these get reduced to a single draw call when rendering an object X amount of times. Normally that that X values would be the number of draw calls you would get. Because of this these objects can not be independently culled.
Using the Hierarchical Instanced Static Mesh will be the best route."
light thunder
Lol how long is the backlog? 2 years?
fierce tulip
sometimes things just dont get fixed
light thunder
So wait... I can't cull any static mesh I drop into the level using a volume?
fierce tulip
@light thunder they are instanced static meshes
light thunder
@stray verge Because it hangs and goes unresponsive
@fierce tulip I'm confused....do you mean instance in that they are more than one of a copy of a stiatic mesh?
so, if I only had one smokestack, it would work
but if I have two, it won't
light thunder
My UE experience is growing but much of my knowledge is fragemented....I know some intermediate things but some of the basics fell through the cracks - how did that BECOME an instance (I am modifying a demo map so I didn't build much of it)
fierce tulip
dunno ¯_(ツ)_/¯
light thunder
so if I highlight them all and "replace" with a static mesh?
How do I fix it, is what I am asking?
fierce tulip
you do know that the cull distance volume doesnt work in editor right?
(unless you press G) but that depends on ue4 version afaik
fierce tulip
probably
light thunder
that one screenshot was during play
fierce tulip
k
if you set cull distance to 9999
only meshes that are about 9999 in size will be culled
light thunder
I thought it was 99999 and BELOW in size?
fierce tulip
closest to
light thunder
Oh.
Strange.
It is as though the knowledge I lack could somehow fill up an object of written language
it's still laughing at me @fierce tulip
how can I get the bounds radius of that smokestack...i want to cull by the exact amount and see what happens
fierce tulip
whats the longest size of that mesh
X Y or Z
add a number close to that in the cull distance volume
light thunder
i would think z
light thunder
fierce tulip
then fill in size 12500 or so, and set cull distance to 500
light thunder
what is that giant line
btw, i'm on a streamed level, however, the cull volume is in the persistant level (and so are the smokestacks)
baffling
plush yew
Anyone know where the manual explains the difference between a memory reference and an asset reference?
Asset reference I assume is just a direct reference between two assets, e.g.: a static mesh referencing a material
What's a memory reference?
livid haven
Memory reference would be any reference that isn't in an asset but instead is merely in memory right now.
Some object that is not an asset.
For example, while you're Playing in Editor, that's a duplicated copy of the level/world all the objects in it.
Those temporary duplicates for Play In Editor are not assets.

Ah, I see - thanks for the explanation!

memory can also mean its still in undo/redo list
