you would have a texture in the metal material that controls that
#ue4-general
frank escarp
and tells the material where to add the rust first
so then you only paint 0.3 red vertex color, and thats only a bit of rust
in the crevices
frank escarp
thats the idea
sacred dune
ok i see what you mean 😃
helps a lot
thks @frank escarp ill look it right now and will test it 😃
ill let you know 😉
this is what i have before changing

Hey guys, i'm c++ on Unreal. So i'm looking for some artists.. It's just for fun or for make something together, maybe eventually ship something. I can make almost everything (for now) on UE4. Cheers! (:

guys, there is a way in UE to get some sort of cavity/height map from one classic texture set (BaseColor/Occlusion/Rough/MEtal/Normal)? i was thinking using the AO must maybe you have one much better idea 😃

annnd thats why i dont upload stuff to youtube
sacred dune
hey guys maybe its impossible but is there a way to get a sort of height/curvature/cavity node inside UE4, in order to use my maps to generate it ?
i see HeightToNormal
but not NormalToHeight
sadly for me 😃
fierce tulip
i remember a post about that, but cant remember where
floral heart
You probably don't want to do NormalToHeight. It can only approximately reconstruct the data.
fierce tulip
sacred dune
what can i use ? i have Base/AO/ROugh/metal/normal
i need that data in orde to tell the water to only go in the cavities
cool @fierce tulip ill check that

hi there, I tried finding the answer for weeks over google, but I guess I can't formulate my question properly, so I'll try here. I have learnt using UE since 2.5, and it's my favorite engine so far. I have never reached the level of expert because I never had the chance to use it professionally so far. Here is my question:
on UE3 and less, to move movable meshes, we use to set up a matinee and have the possibility to change all the parameters over time and especially have a spline in the viewport etc...
The new recommended practice is to use the timeline but, there is no spline anymore like before, the interface is less easy to use (from my point of view) and I am basically lost with this new tool. I have read the documentation but I have the feeling I have missed something.
There is no emergency here since I am not working on that at all at the moment. And I can still use the timeline without problem at all. But I have the feeling it's a lot harder to use now.

shaders compiling
help
it used to not do this but now everytime I drag a material onto a mesh it recompiles the shaders
I just want to manually compile it before I do runtime how can I disable this
thanks
delicate needle
Hello folks! I'm new to Unreal 4. I was wondering in the general workflow, is it possible to edit a mesh in place, back in its orginal software. For example, I make a house in 3D studio max, export the entire model using datasmith, etc and import into unreal editor. After the fact, I find I don't like the details on the front door mesh. Can I edit the converted unreal mesh back in max, and have it update in Unreal? Instance propagation might be the term.
mint raptor
Anyone know which factors effect skeletal mesh performance visually speaking? My skeletal mesh seems to drop nearly 10 FPS per instance for the first 3 and then slightly less for each one there after. At about 24 instances I go from 100+ FPS to 19 FPS. Reducing the bone count from 20 to 10 seemed to double the performance but why would 10 bones be too many?
grim ore
@delicate needle ue4 does support that. There is an option to basically scan for modified files and it will reimport them when it detects the changes. Monitor directories is what it’s referred to in the settings. Or auto reimport.
@plush yew when it compiles it adds it to the cache so it should only do it once. It does however do a best guess for the shader based on what it’s on when you create it and it will make different variations for skeletal and static meshes for example. It’s possible you can have it compile the correct variation by forcing the type it will be used on in the settings for that material when making it but there’s no way of not compiling shaders until runtime that I know of unless maybe it’s for another platform.
austere hinge
Hii.. I want to rotate my car steering in real time with motion controllers.. Can someone help me out
plush yew
ah thanks @grim ore
grim ore
As a shortcut you can probably make the material, drop it on the time, then work on it so it knows by default what it should be compiling for. Might skip a step that way.
plush yew

@sleek spear not all console commands work on a packaged game, as some are editor only
and if you package the game as "Release", the whole command window is out
if you have console command in your own levels and stuff, those will be called no issue on a packaged game

1024x768

ok
cloud cobalt
Though to be fair, very few people will have that
1280x720 is our minimum here
We found that 1280x1024 was common too
sleek spear
i cant understand casting
cobalt turtle
@cloud cobalt my current resolution is 1633768... I would recommend 1024768 as a default resolution
1633x768
cloud cobalt
1280x720 would work too in your case
sleek spear
ok so i have a level "level0", that includes a streaming level. the streaming level has a blueprint actor. i want to cast from level0 to the blueprint actor. what do i use as an object for the casting? please someone, help
cobalt turtle
for sure, but 1280x1024 is a tiny bit too much 😃
cloud cobalt
Yeah, I was giving that one because it's 5:4 and too many games assume the aspect ratio is wide now
cobalt turtle
You are absolutely right.
@sleek spear I can explain you with my own words what is casting, but I don't understand your problem at all. Maybe understanding casting would help you?
cloud cobalt
Casting only means "I have an object X of class B that inherits from class A, I want to cast it to A or B"
sleek spear
let me rephrase it a bit
i have a level "level0" map, in it i have another level for streaming. the streaming level contains a blueprint actor. the blueprint actor contains a custom event in its blueprints. i want to call that event from level0. so i guess i do that with casting? but i cant figure out what to use as casting object
cobalt turtle
hmmm... I'm not sure you need casting for that
sleek spear
alright then, what would i need?
i used consol commands to call these events but they dont work when i build for shipping
cobalt turtle
let's call your actor "myActor":
In level0, I would make a variable "myActor_current" and when streaming the sublevel, I would assign "myActor_current". Then when you want to call that function from your "myActor", you first check is "myActor_current" is valid (with "isValid") and if it is, you can call your function from it.
I'm far from being an expert, so my answer will not worth much... But at least, if it's working, you can use it temporarely
sleek spear
i am not sure i want to add variables
when i do that same thing, casting to the third person character blueprint, it works, i use get player character as an object
cobalt turtle
You always have a controller, and a character... So the editor has a lot of functions bundled to get those controllers and characters easily.
Since you create a custom object, how could the engine be aware about it? You need to declare your variable somewhere! Why don't you want to add variables?
sleek spear
i dont understand how what you described would fire the event on myActor
its confusing
cobalt turtle
- In level0, make a "escMenu" variable named "escMenu_current"
- When streaming your sublevel, set "escMenu_current" to the escMenu actor contained in your sublevel
- In level0 bp, first make a branch with "isValid" from "escMenu_current"
- From the "true" output, execute the function from "escMenu_current"
the more I explain, the more my solution sounds dirty :/
sleek spear
@cobalt turtle how do i set "escMenu_current" to the escMenu actor contained in sublevel?
cobalt turtle
@sleek spear well, I won't be able to help you on this part. My knowledge isn't good enough on streaming. But your casting problem is gone now. You are half the way! Maybe another person could help you from now?
as you said, the only problem now is to set the variable from the sublevel to the main level, or from the main level, you get a variable, or directly your actor from the sublevel
well, I don't like leaving you half way... give me a bit of time 😃 I'll check again how streaming works
oh, I found something interesting
rather than putting the variable "escMenu_current" in your level, how about putting it in your controller? So you can access it anywhere 😃

how do I make an ui with text being buttons?
basically text, press last line, more text or change text I guess, I don't know
the way firewatch does it
grim ore
you can make a button with anything on it as a child, let's say text? then you can just make the button's graphics with a 0 alpha so it's transparent. now you have a button that is just text you can click on.
if you mean like text chat and clicking on it goes to the next line you can always capture the click event on the widget itself, maybe the text widget, and then tell it to load the next part.
plush yew
I actually mean the text fading
and changing to something else, or loading in something else, don't exactly know how I'd make that the way I want it to be
@grim ore
grim ore
well the top white stuff could be just text
the red stuff could be buttons that are hidden with text on them. fading can be accomplished with animations in the UMG system.
alternately the red stuff could just be text as well and you override the on hover and on click events
plush yew
never used the umg system before
so I'd love to hear about how I would actually go about it
I know it's widgets
grim ore
Might need to check out the basics on the UMG system then in the docs https://docs.unrealengine.com/latest/INT/Engine/UMG/UserGuide/
plush yew
yeah, I know about how to make it display and such
but how do I actually make the transitions
and do I just store all of it in variables or just as text
grim ore
There are a ton of ways of doing it. you could just have 10 different white text parts all in the correct spots with only 1 shown at a time. you can have 10 animations that hide the old text and show the new text
and your red text would just play the animation that is correct
you could make an array of text that holds all the text and then when you click it grabs the next text
plush yew
could you make an example project for me?
or are there any online?
so I can look into how exactly it works and see it first hand
I learn better like that
just one transition I guess
grim ore
I can't right now nope, at work.

Why when i jumping on normal box its okey, but when i jump on box "under character" happends this:
https://gyazo.com/72fd80015227068b9b8cbba9af8f623d
I dont know what is going on with this collision on tile map...
wide lark
Guys, I did it. I got a directional dash to work from any direction, and I made it so it dashes in the air almost the same distance as when on the ground instead of a super dash :D
It even has a cool down :3
You have to make sure Can Dash is set to checked as the default setting
wide lark
I don't understand ticks or why they are good or bad
Can you tell me the impact they have?
grim ore
Ticks generally run every frame. If you don’t use them sanely you could cripple your games performance
frank escarp
a lot of stuff also doesnt need to run every frame
grim ore
Your basically saying “hey do all this stuff every time the screen updates”
frank escarp
you can do itin a timer, like once a second
the thing is that if you have tick enabled on too many actors, the engine will slow down just from having to call Tick() on so many things every frame
tawdry quail
if I have a texture I am not mipmapping, is is still important to have it as power of 2?
nvm I answered myself with google
safe rose
@frank escarp yah but how much performance is being saved actually when disabling tick on actors, when those actos have nothing on Event Tick?
frank escarp
more than you would expect
safe rose
The engine still needs to poll all actors to see if Tick is enabled or disabled
frank escarp
no it doesnt
safe rose
Why not?
frank escarp
if the actor has CanEverTick to false
it never even gets registered as a ticker
and costs LITERALLY zero
the other bool (the one that can be toggled) still has overhead
safe rose
Yeah that's what I am talking about
frank escarp
it just has something like "AACtor::PreTick(){ if(bTickEnabled){tick()}}"
safe rose
Not the one you said first
frank escarp
epic devs have talked about it themselves
for vr
becouse vr its 90 fps
so tickers get called tick 90 times a second
safe rose
Right. If there is absolutely no need for something to tick. I get it.
frank escarp
in the bullet system i did in DWVR (for optimization), the bullets dont tick
but the bullets are stored in the bulletmanager
wich actually does tick all of them
safe rose
But when there is and someone is just enabling/disabling tick, that's what I was getting at
If there is nothing on Event Tick
frank escarp
i dont know if it gets disabled in blueprints if you dont have the event tick
i would assume it doesnt, or that it just depends on base class
safe rose
Yeah, guess would be a nice case study. I tried looking the other night for information
Couldn't really find anything. Haven't checked source either.
wide lark
What?
safe rose
The logic behind it can be simple
wide lark
No
safe rose
Lerps?
wide lark
Nope lol
I just started unreal engine this week
I have Jumping, double jump, dash....
safe rose
Just Google it really
I mean this is sort of basic stuff that has been done countless times
wide lark
I tried that.. every one I was pulling up was a double tap dash
I don't want a double tap
safe rose
Then you will have to fix it the way you want
wide lark
Ive been trying that for like 3 days now
This is the only way that works cleanly. Every other way has a weird delay in it
Or the keys won't detect properly
safe rose
Just do it the way you need to do it to work :)
Then later when you are more experienced, refactor it
And worry about optimizations
wide lark
But I don't understand how ticking on the dash is bad
As long as I don't use tons of ticks everywhere, it doesn't seem like it will be a problem
safe rose
Well. The dash itself is event based
The animation root motion
(usually)
You just need to get it from start point to end point

My brain is having trouble following probably because I haven't really done anything with animation yet

Play around, get used to the engine. No matter what you do in the beginning it won't be something you will want to use once you've polished them skills
Do some tutorials, make something you can play around with
grim ore
do enemies, if you want UI just slap something on the screen for now as it won't be what you use in the end anyways
frosty bloom
@glass imp come on dude, you've already been warned twice by Luos, just move it into the correct channel.

alright so as Unity dude learning Unreal
when making a new project
the choice of C++ or blueprint only effects what form the template content is in right?

any idea what will happen to paragon assets?
just sitting on some hard drives at epic? or could it be possible they make it open source

Doubt very hard anyone outside of Epic will see anything from Paragon. They might recycle as much of it as possible into future games etc.
queen arch
anyone knows of a reason why a simple "move to" fails?
it goes to the target, the problem is not that it can't find its target
it just goes there, waits a few seconds and then fails
last night it was working perfectly, I don't know what happened
plush yew
@dawn linden so do you recomend starting new projects as C++ or Blueprint projects then? or does it not really matter
Epic dumping Paragon seems kinda werid
like they had a whole thing at Sony's E3 about it
few years back
like it makes sense to not contintinute active development of a project that isn't doing to hot regardless of how cynical that kind of position is but
@paper kernel long time no see
IF epic were to make Paragon an open source community project which given they're previous releasing of the canceled Infinity Blade stuff, isn't totally out of the relam of possiblity
what do people actually expect to happen
like it'll end up like the new UT
at best
playable but basically abandoned
livid haven
The problem with releasing anything like that is - once you've done it, there's no taking it back. You have forever ruined your ability to ever release a product with that IP without competition from anyone.
plush yew
I mean isn't everything in UT basically still owned by Epic?
like even with all the "community particpation" stuff Epic basically owns all of that stuff right
livid haven
Which is entirely different than "open sourcing" Paragon.
frank escarp
@livid haven they did release infinity blade assets
plush yew
I'm expecting them to make it a "Epic Community Project"
frank escarp
i expect more like infinity blade assets
a simple "here, have some UE4 demo assets"
livid haven
I know about Infinity Blade, but that was also a mobile game and releasing assets from ages ago.
plush yew
we'll let the community "run" the project but with stipulation that we own all of the IP
and they didn't "open source" the IB stuff
frank escarp
doubt it
plush yew
they liscensed it
plush yew
that any UE4 dev can use them for free
livid haven
Yep, that stuff.
Difference with IB is that IB wasn't a modern, ongoing recent project - Paragon was.

hey guys, can someone help me here with unreal engine?
plush yew
yeah they made like three of those games
they were pretty dope
the art assets were from a canceled IB duengon crawler
not the main games that got put out
livid haven
Yes, but regardless, the point is that IB's art assets being released wasn't all that much of an opportunity loss, compared to what happens if they let anyone use the characters from Paragon however they want.
If Epic wants to turn around and revamp Paragon some day or use the characters for something else, they're screwed for having let everyone just go ahead and use the characters for free however they want.
plush yew
compared to what happens if they let anyone use the characters from Paragon however they want.
I don't think that's what anyone is expecting them to do

ehm.. anyone? can someone help me here please
livid haven
@next dome Don't ask to ask, just ask.
plush yew
@next dome well what are you asking about?
frosty bloom
Jumping in with a quick comment. You are talking about a next gen AAA quality game. There is NO way they would give it out in any form or way, to anyone outside of epic.
There is no gain in it, rather the opposite.
livid haven
Ask your question, don't ask if you can ask a question - that's the point of the community.
next dome
so in Urneal Engine VXGI when ever i turn on vxgi im getting this crash error
idk how to fix it
plush yew
if they were to release anything from it at this point, I'd be as an "Epic Communty Project" like the new UT
so something that is nominally "community managed" but is owned entirely by Epic
and is basically more or less stagnant
livid haven
Sure, that's somewhat more feasible, I'd think. Not sure it's likely though.
plush yew
@livid haven wait you work at epic right?

livid haven
Nothing I'd get slammed due to NDA breach for.
@next dome I said you should just ask. If no one is answering, that implies no one knows the answer.
I don't know why you're direct a crash in some rendering code.
But you're also not using an officially supported version of the engine, so... there be dragons.
plush yew
i mean i don't know
livid haven
He's using the VXGI branch from Nvidia, so it'll be difficult to find support outside of Nvidia
plush yew
@next dome the VXGI stuff isn't supported by epic themselves and not many community people use it so I don't know how much help you're actually gonna be able to get
next dome
i mean since its unreal engine discord, i thought someone would know how to solve that
plush yew
i mean i'm a noob
floral heart
Several people here have tried out that VXGI branch successfully. Could be something they've encountered.
plush yew
coming from unity so I don't know shit tbh
worn granite
Yeah I mean its worth asking IMO
next dome
i wanna use VXGI only because when you apply emissive to the mesh, the light from the emissive lights up the map/object too around it, without building lighting, but in official unreal engine you have to build lighting and wait till it builds, i dont want to build lighting, thats why i want vxgi
livid haven
Aye. Can try, but don't assume no one is answering because they're ignoring you - you'll be lucky to find someone who is a) using that branch and b) has any idea how to debug that.
next dome
or is there a way in official unreal engine, to emissive effect the world/objects around it without building lights?
livid haven
That's a really dramatic choice to make just to avoid building lighting.
livid haven
I also don't quite understand what you mean.
livid haven
next dome
and effects the map too
wide lark
I wish there was more free stuff
next dome
yeah that video you sent, the emissive is not really effecting the world, its just bloom effecting the actualy cube and sphere with emissive
floral heart
Neon light on the ground is a light source.
Seems like a silly thing to say, but that's distinct from an emissive material that doesn't serve as a light source.
cursive dirge
well, light building takes forever
you need to make separate UVs for some assets (if not all, I have no idea how good the automatically generated ones are nowadays)
also anything more dynamic and you can't use static lights anymore
like, take fortnite for example
there's no baked lighting
floral heart
How expensive are light functions?
In comparison to shadowed dynamic lights, cached shadowed moveable lights, unshadowed moveable lights, stationary lights... all the lights. On second thought, that would be quite the project.

@sacred dune point is, you shouldn't have lerp on metallic at all
it doesn't give you pbr correct values
you'd either have metal or not
sacred dune
i can just input the fist one in the metallic (the B channel) and thats it for all
?
cursive dirge
you'd need to figure out what part of the final result is metal and what is not
sacred dune
ok maybe you can help me for this. I have One set for the clean metal, the 2 with dirt and used same texture set, the 3 mega rust and 4 water (puddles)
i hva ti tell the material that when i paint water there is no MEtal right ?
cursive dirge
well, you can just bias the lerp result and clamp it, or if you want simpler version just put if -node there
and if the value is below the threshold you want, you put 1 and otherwise 0
sacred dune
bias the lerp result of each ?
cursive dirge
only the thing that goes to metallic
unless you want it otherwise
but try first with if
it's way simpler to get right
might not be as efficient
but that's not important now
sacred dune
so you recommand to put value for metallic in lerps (for the vertex paint) and see what happen ?
like the rust dont have it, as the water
i put constants to lerps
cursive dirge
you want the final value for metallic to be either 1 or 0 usually
sacred dune
yepp
cursive dirge
not something between
sacred dune
ok
floral heart
smoothstep?
cursive dirge
does ue4 already have smoothstep exposed?
or do you still need to use it via custom node?
floral heart
Not sure. I was trying to remember another node, cheapcontrast.
sacred dune
i cant read the link beaucase i cant read this kind of math 😃 sry guys hehe
cursive dirge
anyways, that'll make the transition bit faster but I doubt that will solve the issue
floral heart
Could use an if node if you want to 'solve' it.
cursive dirge
yeah, that's what I've been trying to say here 😄
also, you don't do "metallic boost"
sacred dune
yeah i just erase it
😦
im learning but im going to quiclky without understanding
damn
floral heart
proper docs for this sort of thing are a bit sparse, I think?
sacred dune
the node BreakOutFloat3 is cool but in can use one inverted )
yeah the blends are very blurry.
they show only the base color and not rough , and not with packed maps
and they show only with 2 blends
there is doc but not one real example
i just want to do this kind
but the shared material ha expired and only this image exist
i get shitty results with mine
and after research i have to get a very high floor for that quality of vertex paint
i tried using LerpHeigh to fill the water first and then the rest, without succes.
the only difference is that i put the water on the alpha channel and he out it on the red
put if so on dont see where is has the wood
so lost 😦
3 days searching solutions for this
he said he use vertex paint but i see in his shader some Material layers, so i dont get it... can i paint with that to ?
grave nebula
@sacred dune It is totally fine to have metallic values in between 0 and 1. To get rid of the white outline, you would need to tighten metal map so that transition is biased more in favor of non-metallic surface.
sacred dune
@grave nebula how to do so when i have packed maps and non packed for the blend ?
and thks
grave nebula
you can do it In the material itself
grave nebula
multiplying metal input by itself is usually enough
sacred dune
the top left is the water, the orange is the packed rust maps
sry to ask but i undesrtand why i have to do what you say but i dont see where to do it, on what
sacred dune
ok
grave nebula
ensure that it is in 0 -1 range before doing so though
sacred dune
the 2 fisrt maps are a mix of plastic and metal
the rust is oxyded and water doent need metal
when i paint rust (blue channel)
if i use the same packd maps for the rust and water i get this
not bad
but not sure if its the right thing to do
fierce tulip
afaik its a limitation in the metal pbr workflow in ue4, the only thing I can think of is increasing the contrast between the metal and non metal blending
random idea, try plugging a "round" between whatever goes into the metal and the metal input
sacred dune
ok
fierce tulip
if that doesnt work, try a truncate.
thats all i can think of. though it might result in a too sharp a metal/non metal
sacred dune
with round
pretty nice the transition
sort of a noise 😃
i try truncate
truncate
fierce tulip
ouch hehe
sacred dune
but i think that with what you told me i get somting i like
fierce tulip
are your metal/roughness textures set to RGB instead of SRGB btw?
sacred dune
yep
fierce tulip
hm
fierce tulip
yea i just noticed it
sacred dune
but now all my mat is guided by the AO/Rough/Metal of the two maps, so i dont have the control on the water rough
fierce tulip
not longer than a few days
sacred dune
i think i got it
but
i use the same value for all 4 channels so my roughnees is lost for the water and rust
i dont know i to have the same ramification than the pakaed map when i dont have it for water
can i put 2 constants and tell to a node that one is G and the other B, in order to plug it to the lerp ?
this its what i mean
they changed the doc some hours ago i went all day long and its was not updated
harsh tiger
im making a game similar to the trails S.P.H.E.R.E gamemode and i've made a few maps and i was wondering how I would create a editor to allow players to create their own maps and then save them to play again. i've done some research but finding it really hard to find information on this type of thing.
any help is appreciated

tough jungle
grim ore
well the direct link is https://www.epicgames.com/fortnite/en-US/news/mobile-announce which might be easier
grim ore
chances are no as a character has things like the character component as part of its base class that you would inherit. You can try changing the parent class to character in your blueprint and see if that works for you.
plush yew
I mean I merged actors with developer tools -> merge actors
grim ore
well then no for sure as that is just static mesh actors I would assume
plush yew
and now I have a group of actors in one but I think it is static only
yeah dang
is there no way to make it a skeletal mesh or something idk
grim ore
you could always turn that into a blueprint then repararent it?
definitely not unless you export it out and bring it back in
plush yew
will I still be able to use and change materials if I export it?
grim ore
but even then if you expect it to work like a character and a skeletal mesh you would still be missing the actual skeletal part
if you export it out as a fbx then yeah you can do whatever you want in your program and bring it back in
grim ore
it should export out with the same material slots
plush yew
not the bones?
grim ore
the mesh is the thingy you see, the skeletal part is the skeleton and weighting part of it
plush yew
ah
grim ore
right now its just a static mesh as it has no skeleton or weighting or rigging
plush yew
I'm confused at how the layout works
not how the 3d models and bones work
still getting used to unreal
with my first project I had a mesh as the skeletal mesh idk
grim ore
yeah the static mesh actor is just going to be for looks mainly. Technically you can animate it by hand but you wouldn't really get much out of it in terms of animations and such. IF you just wanted it use it as a basic mesh in a character you can export it out, then reimport it back in and tell UE4 its a skeletal mesh and it will bring it in with no real bone setup
but that would let you slot it into a character
plush yew
I made a character blueprint
and I cant set the mesh as the merged actor is what I mean
I guess I am stupid
and should have known that wouldn't have worked
idk what to do lol
grim ore
well I just tested and what I suggest does work.
you can export out the merged mesh, save it somewhere, then import it back in and tick skeletal mesh to change it over
this would atleast let you drop it into your mesh slot on a character
plush yew
where do I export it
grim ore
right click it in the menu, asset actions, export
alternately you can just cheat and make a static mesh as part of your character and use that and just keep the skeletal mesh empty
the Skeletal mesh doesnt really "do" much but show up and animate, the rest of the character is what handles moving and collision
grim ore
well yeah you will get errors since it's not a real skeletal mesh and you never really messed with it but it would work as a basic.
honestly I would just add a static mesh to the character and plop it in there and see how that goes
unless you plan on animating this in blender and adding a skeleton
plush yew
wait suprisingly I can still use materials
sweet
it works I guess
which method is better
the cheating part or fbx export
grim ore
do you plan on needing the skeletal part of this mesh? if not just keep it as static
plush yew
I don't need skeletal part of mesh I just need it to be a character pawn
pretty much
be able to be used in a character pawn*
sorry for asking you even more questions but uhh
in the character blueprint pawn thing editor thing
is the capsule component the hitbox or is that just useless
idk
grim ore
It's the hitbox and it's also where the movement is applied against basically
the character class has a ton of stuff that drives how it works, the character movement component is what controls how the movement works and the capsule is basically it's hitbox and also collision for moving
plush yew
the bevels look bad now
new:
old:
anyway uhh
it is the hitbox
got it
lemme make it bigger
when I made my capsule bigger my mesh got bigger
@grim ore
grim ore
the mesh is a child of the parent, if the parent gets bigger the children will as well relative to them.
leaden wave
How do I make a blueprint character class that has an actor component that inherits 1 function and all it's required variables from a pre-existing .cpp file?
grim ore
scale down the mesh to fit in the hitbox

ember dove
I've never even heard of that 
next badger
@humble shuttle no...but i assume it somehow related to game mode... have you debugged it? does the branch that runs animation event triggered?
humble shuttle
yea, i've debugged it, the play animation BP node I'm using is running
I've also tried setting the animation mode on the skeletal mesh to "use animation asset" and i point to the same animation, but that doesn't work either :/
grim ore
@tender ginkgo the Projectile itself handles itself when it is spawned in. If you open the BP for it you can see it is using a projectile movement component and adjust the speed in there

granite sky
are there any caveats with TSet remove that I should know about?
because remove returns true, but the object is never removed
granite sky
the set length is 1 before the remove, and is 1 after the remove - looking at the TSet source, I can only assume that the actual remove command is failing, because the counter for number of removed objects is incremented following that, and if that counter is > 0, it returns true

Hello Guys, I want to know is it possible to add installed UE4 in my previous windows to Epic Games launcher without re download them again ? They're installed in my other drive.
devout gulch
@surreal viper Niagara in 4.19 is very useable
It's complicated as fuck
and I have no idea what I was doing
I had*
but it didn't crashed
and have everything you need to create FX
that being said I expect something else a bit
I mean from graph based FX editor I expect that actuall emitters will be placed on Graph like nodes
where you can directly code some logic
to emitters
I mean to which emitters are used
tall pendant
you dont place emitter as nodes? huh thats a bit odd
devout gulch
like if this emitter spawned 10%5 particle trigger this emitter else this emitter
no you place them in side panel
otherwise everything else is node based
tall pendant
aye. i have to give it a shot when 4.19 goes final
devout gulch
but I doubg average VFX artist make any use of it, it's heavy math stuff
I can't even speculate much I really need some 101 expalantion of how it works
tall pendant
I'm interested in whats their plans for a transition phase cascade -> niagara
devout gulch
I assume it can be far easier controller just from blueprints, that'w why you don't really use emitters as nodes
tall pendant
since i doubt everyone will/can just switch
devout gulch
you probabaly won't be able to click on cascade particle and convert it
they will rather focus on recreating all the default functionality of cascade
right now it's pretty bare baone
bone*
devout gulch
my speculation (;
the might pull it off
but no sooner than all the cascade modules have equvalent in Niagara
equivalent*
tall pendant
yeah. i guess we have to wait a few months and see how it develops
devout gulch
anyway, I really excitied for the GDC presentation

i can create such tool b blueprints ?
languid shard
yep

so you create the tools you need directly inside ? thats why i don t find many tools ?
can a bluprint bend a mesh ?
languid shard
well you can't bend a mesh with blueprints
you could do it with a material offsetting vertices or pixels
sacred dune
amazing
languid shard
you can also use spline meshes
sacred dune
so no tools to duplicate many times rapidly , except making one in Blue
whats thats ?
languid shard
meshes following a spline
to make roads, railworks, cables
you can make an array tool quite fast with blueprints
sacred dune
so cool!!!
