#

How performance heavy is it going to be for me to modify a greyscale mask in shader as far as the curve/level/threshold

#

I see there is a 3 point curve function

#

I made a greyscale mask which is like a infintstly variable color mask for customizing a character

Is there a way to force the order in which material slots are listed for a mesh? It seems like they are forced to be ordered alphabetically

Hey, just wondering how hard it would be to make a "berries" system for plants.
I currently have a simple bush actor that can be harvested and send items to inventory, but I would love to make this a "multi-step" process, basically allowing the user to "pick berries from bush" instead of harvesting the entire bush system. Making this in code is quite simple, but I'm more about the visual representation of the berries (make each bush display the berries it has left on the bush, and remove 1 and 1 berry from the object as they get harvested)

plush yew Sep 30, 2019, 9:02 PM

#

If it's a long process I'll skip it for now, but maybe you guys know any "simple" ways to do this

#

@plush yew you could just make the berries harvestable instead of the bushes?

crude vessel Sep 30, 2019, 9:02 PM

#

Doesn't UE4 have a socket system for attaching meshes?

plush yew Sep 30, 2019, 9:02 PM

#

@plush yew with the current code you got basically

#

Hmm that's fully possible, lemme check

#

seems like a quick win

crude vessel Sep 30, 2019, 9:03 PM

#

Have the berries be a discrete mesh that plugs into the bush socket?

#

And they would be instanced right?

leaden mauve Sep 30, 2019, 9:03 PM

#

I guess use multiple meshes for the bush @plush yew ?
a "Bush" and 50 "Berries1-50" ?

plush yew Sep 30, 2019, 9:03 PM

#

@leaden mauve Sounds like a really ineffective solution

#

sure, the easiest, but for sure ineffective

crude vessel Sep 30, 2019, 9:03 PM

#

Or have each berry be a bone and just shrink the bone?

leaden mauve Sep 30, 2019, 9:03 PM

#

A solution nonetheless 😄

crude vessel Sep 30, 2019, 9:04 PM

#

Then the bush could be rigged sekeletal mesh

#

Why not!

plush yew Sep 30, 2019, 9:04 PM

#

just use LODs on the berry mesh and you should be fine i'm guessing

crude vessel Sep 30, 2019, 9:04 PM

#

It would be like dismemberment

plush yew Sep 30, 2019, 9:04 PM

#

@crude vessel Haven't worked much with meshes/skeletons, quite new to the whole graphical concept

crude vessel Sep 30, 2019, 9:04 PM

#

Except a bush

#

I saw someone ported an old Ue function to blueprint on the forums

#

In regards to dismembering people

plush yew Sep 30, 2019, 9:05 PM

#

I'm a trading algorithm developer that wants to play with UE4 as a hobby

#

i think it might be overkill to makes sockets and bones and whatnot for this

crude vessel Sep 30, 2019, 9:05 PM

#

It would shrink a body part down to nothing

#

Hehe

#

Well it depends on how interactive it has to be

#

Or how detailed you want it to be

#

How about a particle system?

#

The berries are just particles and a int variable controls how many berries are in each bush?

plush yew Sep 30, 2019, 9:06 PM

#

then you need something else anyway if you want to harvest by aiming at them

crude vessel Sep 30, 2019, 9:06 PM

#

Well is that required?

plush yew Sep 30, 2019, 9:06 PM

#

cant do raycasts on particles i assume

crude vessel Sep 30, 2019, 9:06 PM

#

Or is it more abstracted?

plush yew Sep 30, 2019, 9:06 PM

thats kindof what he showed in his example

crude vessel Sep 30, 2019, 9:07 PM

#

Can you cull particles inside a collision volume?

plush yew Sep 30, 2019, 9:07 PM

instanced mesh is proably the way to go tbh lol

crude vessel Sep 30, 2019, 9:07 PM

#

I mean, even something as simple as this

#

would do the job

crude vessel Sep 30, 2019, 9:09 PM

#

I haven't messed with too much in depth stuff beyond some tutortials, been wasting all my time on a character asset I've been porting into ue4

#

But you can combine meshes in one blueprint object?

plush yew Sep 30, 2019, 9:10 PM

#

I guess?... lemme try

crude vessel Sep 30, 2019, 9:10 PM

#

So it seems simplest to just have a bush with berries, or have a bush that spawns berry objects in space

#

Unless you have we to have it sway in the wind together

#

Or react to player touching it

#

Is this something like the forest?

#

Or berry picking simulator 2000?

#

Because in the Forest it just seemed like they had a bush mesh with berries, and one without, and it swapped between the two?

#

Or maybe the berries were a sub mesh

haha sorry confused you with Buster

#

No idea whether this is a good solution, but I added the berry mesh to the bush object as a separate "component"

#

nice does it pick them one by one if you have multiple on the same bush?

#

📎 unknown.png

#

@plush yew Can just make a quick array loop function for that

#

if the bush was slightly more dense you could even place them random so every bush looks more unique

#

Yeah this is just a placeholder

#

but placing them randomly might be a bad idea, unless I make it only place it on the outside

#

otherwise you won't be able to see how many there are

#

yeah on a few spheres or something

#

so some are slightly more inside then others

can you ping the server from remote?

storm venture Oct 1, 2019, 1:10 AM

we can with other applications

#

not with unreal though

plush yew Oct 1, 2019, 1:11 AM

#

try setting the ip you can reach the server with in the settings as unicast endpoint (port 0)

#

if that doesnt work just look at the network interfaces of the server and find out which one is used for remote access

#

then try the ip set to that

#

if that doesnt work talk to IT lol

in fact talking to IT is probably recommendable anyway

you'll need some sort of VPN like solution

#

wont work because your computer does not (likely) have an internet IP, your router does NAT

storm venture Oct 1, 2019, 1:14 AM

#

we're trying to avoid VPNs, i imagine there should be a way to port forward and host a listening server for the multi-user tool

plush yew Oct 1, 2019, 1:15 AM

#

you could find out what ports to forward but if you get something liek a VPN you can work from anywhere where the VPN works

#

i'm not sure whats a good tool for home use without a server

storm venture Oct 1, 2019, 1:16 AM

#

i mean, i might sound dumb by saying this, but i can host servers for videogames (like mordhau, minecraft, etc) and the process should be the same

#

port forward the required ports, host the server, send required IP:PORT to friend?

plush yew Oct 1, 2019, 1:17 AM

#

it uses multicast so seems unlikely its even gonna work with portforwarding

warped tangle Oct 1, 2019, 1:17 AM

I'm pretty sure you need to VPN/be on the same network for multi-user sessions. Epic just did a livestream about this I think last week. I haven't had a chance to fully watch it yet but I'm pretty sure that was a part of it

plush yew Oct 1, 2019, 10:15 AM

that can become an incredibly complex question depending on what you mean

oh... ok...

#

is there another way?

plush yew Oct 1, 2019, 10:17 AM

#

anything that involves modifying geometry requires you to use procedural mesh, static meshes by design can't be modified, brushes by design are built at authoring stage because they are slow and are usually only used for whiteboxing

#

another way and the simplest way is to fake it

#

you have to fake a lot in game dev

Hi, is it possible to import a spline to unreal engine 4.21?

Spline Importer Plugin by Daniel Vuljanic in Code Plugins - UE4 Ma...

Import external spline/curve data and use them as USplineCompoents.

#

though looking at the legacy comments, hmmz

magic ermine Oct 1, 2019, 12:02 PM

#

@fierce tulip thank you so much, I saw this, this is not working for me, I don't use 3dsmax. I use blender or c4d for this. anyway thats plugin in not for sale

fierce tulip Oct 1, 2019, 12:05 PM

#

hmm, cant find any info on blender support.
what is your purpose of wanting to import a spline? they should be somewhat easy to make in ue4 itself.

plush yew Oct 1, 2019, 12:08 PM

#

dae or collada is just a bad format in general

#

if anything can replace fbx it would be gltf, but it needs industry support

magic ermine Oct 1, 2019, 12:08 PM

#

@fierce tulip I want to import splines and use it as a road or railway, I have osm files and all this data is sitting there, I want to export from a blender as fbx or obj

#

@plush yew I can export gltf

plush yew Oct 1, 2019, 12:12 PM

#

I'm not sure if the new enterprise stuff has something to import splines, but afaik you need to reconstruct splines inside unreal, or convert the spline thing to a mesh and export normally

#

it depends on which 3d program you are using though

tall pendant Oct 1, 2019, 12:12 PM

#

on the new format race gltf vs usd ... usd might win

serene birch Oct 1, 2019, 12:12 PM

#

usd?

#

ah, I see

#

what is UE4 support for USD so far?

plush yew Oct 1, 2019, 12:13 PM

#

usd support will probably come to ue4, but probably won't be gamedev oriented

magic ermine Oct 1, 2019, 12:14 PM

#

@plush yew does it mean that I can convert the spline to a regular mesh, and later in a engine convert it again to a spline?

plush yew Oct 1, 2019, 12:15 PM

#

no just use it as a mesh, and if you need to modify it you modify it from source and reimport, obviously not ideal

#

better way would be to recreate it inside the engine

#

that depends on the content etc, a lot of things to consider

#

just mentioning it as a general thing

serene birch Oct 1, 2019, 12:16 PM

#

USDZ has Apple, Pixar, and Adobe behind it, but glTF has Microsoft, Google, and Facebook
damn 😄

plush yew Oct 1, 2019, 12:18 PM

#

meanwhile fbx still has autodesk behind it 😄

magic ermine Oct 1, 2019, 12:18 PM

#

yes, but I need to create a road in the engine, I have a lot of kilometers of roads or railway, I want to adapt to the terrain later

plush yew Oct 1, 2019, 12:18 PM

#

that isn't a good workflow in general, if you want it as a level you are almost always better off working in the engine

#

first you can always enter the game and look around

magic ermine Oct 1, 2019, 12:19 PM

#

@plush yew I have GIS data in osm file

plush yew Oct 1, 2019, 12:19 PM

#

anyway that is how I would do it, your project might be different, but I believe this is the preferred workflow

#

if you have such a data ready best way to do it would be handling it via blueprints or c++

magic ermine Oct 1, 2019, 12:21 PM

#

yes, but for small projects, if you have a road 1000 km you will do it for a long time, I want to save some time

plush yew Oct 1, 2019, 12:21 PM

#

doing it from another app and importing doesnt make sense

#

there was a openstreet plugin made by someone that did a similar thing

#

https://github.com/ue4plugins/StreetMap

#

this is all c++ though

magic ermine Oct 1, 2019, 12:22 PM

#

ooo @plush yew thank you, I check this

crude vessel Oct 1, 2019, 12:32 PM

#

I'd like some advice from someone more informed on this. Right now my character has 4 materials, everything for the body, the mouth/tongue, the teeth,and I want to use that procedural eyeball material. Mouth/tongue and teeth texture are going to be used across multiple characters. While the body texture might be modified for each character. I could combine the teeth and mouth but I wanted to use a simple solid fill material instead of fully textured.

#

So TLDR: is it performant to share a common material across many characters even if it's a separate material, as opposed to wasting texture space by packing the same data into a single texture?

serene birch Oct 1, 2019, 12:33 PM

#

it's more the extra draw calls that will impact performance

crude vessel Oct 1, 2019, 12:34 PM

#

Yeah but if the materials are the same, won't that be the same across all models?

#

Like if 5 characters have identical materials for their mouth mesh, like instanced?

#

Maybe I misunderstand draw calls then, I thought the same material got drawn at one pass

#

Also would a more complex material be preferable to two simple materials?

serene birch Oct 1, 2019, 12:35 PM

#

the combo of "model/material params (aka textures) makes a draw call more or less (well shadows had extra copies of the draw)

#

UE4 might auto batch together in a single draw call all the tongues of your NPCs if they are all the exact same model and material, only changing on position (starting from 4.22)

crude vessel Oct 1, 2019, 12:36 PM

#

Maybe I just need to do a demo map

#

With a ton of NPC and see the performance difference between packed textures or discrete materials

#

For LOD I pretty much drop the extra materials

#

Since you won't really see inside their mouth after a certain distance

serene birch Oct 1, 2019, 12:37 PM

#

measuring is always a good way to go at performance!

plush yew Oct 1, 2019, 12:37 PM

#

skeletal meshes never get batched, more materials are more draw calls

crude vessel Oct 1, 2019, 12:37 PM

#

Yeah, but I'm still learning and I figure thia might be a straight forward question

#

Damnit oka

#

Good to know

plush yew Oct 1, 2019, 12:38 PM

#

even if every character will have them, it is better to include them inside the normal character texture

crude vessel Oct 1, 2019, 12:38 PM

#

Okay so then I might just need to go back to my idea of a super complex masking system :)

plush yew Oct 1, 2019, 12:38 PM

#

you can compromise and reduce their size on the texture though

crude vessel Oct 1, 2019, 12:38 PM

#

The issue isn't just that it's the workflow

#

But I might bake them out and just manually composite them into UV quadrants

#

My main character texture is probably going to be very busy with a series of variable masks

#

I want to make a customizable material to generate characters that look unqiue

#

But if each skeletal mesh has a large shared texture set, the draw calls will be larger but texture memory will be lower

#

I guess the other option is to render out each texture to a cached yexture

fierce tulip Oct 1, 2019, 12:41 PM

#

in that case you should (if you havent already) do extensive research on good approaches, see how others did it trough documentation, tutorials, and potentially look at how people did it in their char customizer projects they released on the mp.

crude vessel Oct 1, 2019, 12:41 PM

#

Thant would simplify the material but baloon the texture memory

#

Right now what I'm doing is very specific

#

So it's probably more complex than what I've seen in other games

plush yew Oct 1, 2019, 12:42 PM

#

skeletal mesh performance is problematic in unreal

#

they have a combine mesh system, but it can bloat the memory since it creates a new texture for every mesh

crude vessel Oct 1, 2019, 12:43 PM

#

Is skeletal mesh including a non deformed mesh attached to a character bone via blueprint?

plush yew Oct 1, 2019, 12:43 PM

#

best bet is to limit yourself to few parts and limit the number of characters on screen

#

that is what fortnite does

#

also aggressive lods

crude vessel Oct 1, 2019, 12:43 PM

#

Aggressive LOD I can get on board with

plush yew Oct 1, 2019, 12:44 PM

#

my unreal-fu isn't that up to date, but that should still go through the dynamic path, not sure if the new renderer improvements can batch dynamic path or not

crude vessel Oct 1, 2019, 12:44 PM

#

But the issue is I'm probably going to have some kind of modular clothing/body part setup, but I know that's gonna be a mess

#

But one of my project goals is literally spinning unique NPCs

plush yew Oct 1, 2019, 12:45 PM

#

you are not going to be able to get good performance with a modular skeletal mesh setup without getting your hands dirty on the engine side

fierce tulip Oct 1, 2019, 12:45 PM

#

you might want to consider having things like tongues, eyes, certain accessories to be separate entities which you can LOD out depending on distance and such.

plush yew Oct 1, 2019, 12:45 PM

#

(unless skeletal mesh numbers are few that is)

crude vessel Oct 1, 2019, 12:45 PM

#

I'm trying to avoid army of clones look

plush yew Oct 1, 2019, 12:45 PM

#

how many skeletal meshes would be on screen at one time?

crude vessel Oct 1, 2019, 12:46 PM

#

I guess face concealing helmets and uniforms eh?

plush yew Oct 1, 2019, 12:46 PM

#

you might end up running into cpu bottleneck as well with character movement component etc

crude vessel Oct 1, 2019, 12:46 PM

#

I'm determine, I'm not going for fighting an army

plush yew Oct 1, 2019, 12:46 PM

#

this is a multifaceted issue

#

animation can get expensive etc

crude vessel Oct 1, 2019, 12:46 PM

#

Well agreasive LOD but I'm hoping to simplify the movement issue of background Npc

plush yew Oct 1, 2019, 12:46 PM

#

anything about skeletal mesh is expensive 😄

#

or rather 'character' as a package is expensive

crude vessel Oct 1, 2019, 12:47 PM

#

What's the best way to test certain optimizations, I noticed with LOD I can limit bone influences per vertex, or even remove.bones

#

I'm wondering the best way to test performance gains of this

plush yew Oct 1, 2019, 12:48 PM

#

last year there was a fortnite gdc talk about this, how they cut up characters into different chunks, their cost, animations etc, you could watch that to get an idea

crude vessel Oct 1, 2019, 12:48 PM

#

Good idea, thanks

#

Yeah I was modding Overgrowth and the character script/physics really killed the performance

#

You could have maybe 6 characters active before it got unplayable

#

Disabled (no script) you could have 70 on screen easy

#

So I kind of get that all the nice little things can add up real fast

#

So maybe I'll prototype with my multiple materials and bake down the materials when finished

plush yew Oct 1, 2019, 12:52 PM

#

flexibility is more important than performance when you are prototyping

crude vessel Oct 1, 2019, 12:52 PM

#

I'm still curious about simple materials (say a solid color and roughness value) vs a material with textures or masks

plush yew Oct 1, 2019, 12:52 PM

#

multiple materials make much more sense for that

#

in a real scene they shouldn't matter

#

unless you are going ham with textures and masks, they shouldn't matter that much

crude vessel Oct 1, 2019, 12:53 PM

#

Well in past modding

#

I realized once you start iterating vartions it can explode

plush yew Oct 1, 2019, 12:53 PM

#

it would matter if you do material layering though

#

but that isn't just simple texture masking

meager copper Oct 1, 2019, 12:54 PM

#

hey. I would like to animate the background (an animated texture maybe) to create an effect like shown here (http://alkemann.com/webroot/retro/starfield/ click mouse at different areas or click and drag). Is this possible in UE4?

#

i dont meant to ask for the details of implementation, just if possible and where to look to get started

plush yew Oct 1, 2019, 12:55 PM

#

possible, in variety of ways, but depends on your knowledge

#

you could do it in a shader, or via blueprints etc

meager copper Oct 1, 2019, 12:55 PM

#

can u draw pixels to a texture using blueprints code maybe?

plush yew Oct 1, 2019, 12:56 PM

#

depends on how you want it, what you are good at etc

meager copper Oct 1, 2019, 12:56 PM

#

this is made with a loop and drawing lines in x,y space

crude vessel Oct 1, 2019, 12:56 PM

#

Well here is the deal, with material layer a simple RGBA is not enough. Unless I'm doing like stacked masks in UV space, and I could split the value range to get more masks

plush yew Oct 1, 2019, 12:56 PM

#

if you want it as a texture only you are probably better off doing it on a shader

#

you can do dynamic textures in blueprints, but they would be very expensive for a background

meager copper Oct 1, 2019, 12:57 PM

#

what are the alternatives to as textures? i mean i dont see this done with 3d objects in the background

plush yew Oct 1, 2019, 12:58 PM

#

you could do this in a shader if you know how to program shaders, then replicate it via material editor or just use custom node for it

meager copper Oct 1, 2019, 12:58 PM

#

i can have it on a plan, far underneath the player pawn and it moves with the player, so the placement is taken care of there. and to get the speed, maybe have a couple of animated gifs that it switches between?

plush yew Oct 1, 2019, 12:59 PM

#

typically, doing dynamic things with textures in unreal is a bit problematic and not intended for general use

meager copper Oct 1, 2019, 12:59 PM

#

i dont know how to program shaders. but the whole point of this project is to learn new things, so if you have a link to a good resource, maybe a youtube series, for that, I would be much obliged 🙂

#

(ofc I could just search for it, but I have found a lot of bad results going blind search for unreal tuts)

plush yew Oct 1, 2019, 1:00 PM

#

probably won't be able to find unreal tutorial for this since it is very specific 😄

#

you could use flipbooks (gifs) or simply a video file if you don't want it to be dynamic

meager copper Oct 1, 2019, 1:01 PM

#

so basically how do you write a shader to do procedural 2d animations?

plush yew Oct 1, 2019, 1:01 PM

#

if you want to learn shaders you can take a look at this, but it would be overkill to learn how to program shaders just for this, anyway here's an example https://www.shadertoy.com/view/WsfGDM

Shadertoy

#

hackiest way would be to do this in 3d somewhere else in the level and use render to texture to get a dynamic texture off of that, it would be needlessly expensive, but would be the simplest approach that is still dynamic

#

https://www.shadertoy.com/view/3dSXWt this is a bit close to your example

Shadertoy

meager copper Oct 1, 2019, 1:04 PM

#

and this code is pluggable into an UE4 material?

plush yew Oct 1, 2019, 1:05 PM

#

nope, its not even a language that is supported by unreal, but you could convert it to hlsl

#

why do you want it as a texture?

meager copper Oct 1, 2019, 1:06 PM

#

not that i want it as a texture, it just seemed like the likely approach

#

since it is 2d background

#

basically i am recreating this http://alkemann.com/webroot/retro/asteroids/ in UE4 because i enjoy learning new things more than creative about what to make 😉

plush yew Oct 1, 2019, 1:08 PM

#

oh, you could just do it in 3d though?

#

you could probably do it in cascade or niagara as a particle effect

#

i was gonna say maybe try particles

meager copper Oct 1, 2019, 1:08 PM

#

hmm.. yea i probably havent been considering particle system good enough

inland kettle Oct 1, 2019, 1:08 PM

#

Hello everybody, my goal is to move stars in the background. Like a spaceship starting and braking. So i start a simple timeline (Float / 0 to 1) and control a scalar-parameter that controls the speed of a pannernode (Starmaterial on a plane). Forward this works fine. When I play the timline "Reverse", the speed is getting less again, which is ok, but my stars are moving in the opposite direction. My goal is a clean acceleration and braking. Can anyone help out?

fierce tulip Oct 1, 2019, 1:09 PM

#

^ hehe related to alkemans

plush yew Oct 1, 2019, 1:09 PM

#

cascade is pretty good, with niagara you can use visual programming to add your own stuff, it is crazy flexible

meager copper Oct 1, 2019, 1:09 PM

#

haha convergent ideas 🙂

plush yew Oct 1, 2019, 1:09 PM

#

should be pretty cheap and straight forward with particles

fierce tulip Oct 1, 2019, 1:10 PM

#

Tower, odds are that the value that is moving the panner turns negative, you might need to find a way to remap values.

inland kettle Oct 1, 2019, 1:10 PM

#

i have checkt this. it is positive all the time

plush yew Oct 1, 2019, 1:11 PM

#

ok, make it turn negative :-p

fierce tulip Oct 1, 2019, 1:11 PM

#

I dont know in what situation you want the stars moving towards screen @meager copper but a simple gpu particle setup should work, perhaps have some shader math influencing verts so particles always move away from center of screen.

meager copper Oct 1, 2019, 1:11 PM

#

@plush yew so I should look at particles and Cascade and Niagara are key words for tools?

fierce tulip Oct 1, 2019, 1:11 PM

#

niagara is not superduper ready for production, cascade can do this

plush yew Oct 1, 2019, 1:11 PM

#

cascade is the proven one, it is production ready, lots of resources, I would recommend that

fierce tulip Oct 1, 2019, 1:12 PM

#

@inland kettle care to show the material for the pan stuff?

plush yew Oct 1, 2019, 1:12 PM

#

if you think cascade is a bit too limited for something, then you might want to look at niagara, but I would still recommend sticking with cascade

meager copper Oct 1, 2019, 1:12 PM

#

basically the particles (remote suns) should always move from a point on the screen, FAR away, towards the screen, but always to the sides, spread randomly around, never hit the play area

plush yew Oct 1, 2019, 1:13 PM

#

yeah but its jsut an effect right?

inland kettle Oct 1, 2019, 1:13 PM

#

Not at all. One moment

#

Panner

📎 Panner.png

fierce tulip Oct 1, 2019, 1:14 PM

#

@meager copper there are ways to make sure stars do not move into the screen by some math into the vert offset in the shader

#

what is the panner set to, and from what value does the speed go trough the timeline?

plush yew Oct 1, 2019, 1:15 PM

#

maybe jsut keep it flat, nice and simple, spawn in the middle, move them faster and faster to the side

meager copper Oct 1, 2019, 1:16 PM

plush yew Oct 1, 2019, 1:16 PM

#

i mean scale them

fierce tulip Oct 1, 2019, 1:16 PM

#

well, his is texture based

meager copper Oct 1, 2019, 1:18 PM

#

which I also assumed mine had to, but i think particles may be better option for me

severe ibex Oct 1, 2019, 1:18 PM

This is quite general, not sure where to put it but the company I work for is looking for some Unreal support from able professionals. I keep seeing Fabrice Bourelly pop up but the one time I met him he was not so impressive and he cancelled his talk because it was "getting late". Is there some Epic Games email or person I could contact?

fierce tulip Oct 1, 2019, 1:18 PM

#

either (and some others) all have their pros and cons

plush yew Oct 1, 2019, 1:19 PM

#

you could always use a video loop, but personally i would go for particles

@fierce tulipthanks. I'll look it up. I've heard of the partnership program so I'll look again.

plush yew Oct 1, 2019, 1:21 PM

#

you could probably do the star effect with texture by panning a starfield texture on a cone mesh and layering them

#

you could also use some simple vertex coloring or uv mapping to change the cone top vertex location so that the thing would look dynamic

#

it would take a lot longer than simple particle system though 😄

So basically offsetting the texturecoord by hand

fierce tulip Oct 1, 2019, 1:34 PM

you dont need to use a timeline that goes back that way

just add to it until a certain value.

just a compare and a set i would say

can i put anything on that first black screen when you open the game?

#

like loading screen

inland kettle Oct 1, 2019, 1:49 PM

#

Unfortunately that was not the solution. But thank you very much for the effort.

#

I wonder how others do that. - A star background controlled by a timeline to simulate speed acceleration & braking process

fierce tulip Oct 1, 2019, 1:55 PM

#

dont run the values trough a timeline moving backward.
it should only ADD to it unless you go backwards.

inland kettle Oct 1, 2019, 1:57 PM

#

The Problem is, i need a curve.

#

And i want to switch the curve at runtime

fierce tulip Oct 1, 2019, 1:59 PM

#

you can ramp the value

inland kettle Oct 1, 2019, 1:59 PM

#

On top of that the Background should run at all time. exept 0

fierce tulip Oct 1, 2019, 2:00 PM

#

could always add a time node with a low value that constantly adds to it.

inland kettle Oct 1, 2019, 2:01 PM

#

yea but withot a curve it is not smooth enough

#

hm...

#

It would be a great pity if I could not use the curve system.

fierce tulip Oct 1, 2019, 2:03 PM

#

there should be some bp nodes that are related to curves and what not

plush yew Oct 1, 2019, 2:03 PM

#

why do you need the curve?

inland kettle Oct 1, 2019, 2:05 PM

#

@fierce tulip yeah. let's see what I can get out it

#

Its a effective fast system. I want to sitch fast betwen these curves

plush yew Oct 1, 2019, 2:06 PM

#

i think you just need an exponential decrease / increase when stopping or starting movement

inland kettle Oct 1, 2019, 2:07 PM

#

it should be like a acceleration curve from a car for example

plush yew Oct 1, 2019, 2:07 PM

#

so basically you double the speed or divide by 2 until you are at your desired speed or 0

#

curve seems way overkill for this imho

inland kettle Oct 1, 2019, 2:09 PM

linear is no problem, just add the speed instead of multiplying

Hey everyone. Currently I am looking into options on how to realize a runtime procedural landscape generation and which option might be the best to go with...

Actually it would be great if I could use UE4's landscape class for it, but as far as I see (in code) most of the implementation is editor only. Is there a way to manipulate landscapes at runtime? It would be great if I could give a landscape a heightmap at runtime and it does the work for me.

The other options that I see are to use Procedural Mesh Component or Runtime Mesh Component. How do they compare in terms for functionality, performance, LOD etc. to landscapes?

Are there any other plugins that have proven to do the job?

plush yew Oct 1, 2019, 2:12 PM

#

you can do everything without curves unless you want some fancy curve shape basically

#

(and even then you could argue about it lol)

inland kettle Oct 1, 2019, 2:12 PM

#

Ok 😄

#

No Curves for Tower

#

🙂

plush yew Oct 1, 2019, 2:13 PM

#

the only difference is your ship acceleration curve is now defined in the code and not in your curve, but you can turn it into a parameter or whatever

#

this could be benifitial i you plan on upgrading shipsd to make em faster and whatnot

#

jesus i cant spell

#

(i'd have to say though linear seems unrealistic if its in space)

inland kettle Oct 1, 2019, 2:16 PM

#

Oh. Missunderstanding. This was the answer for the "change acceleration speed " thing.

#

I was looking towards the curves because its no linear thing.

Hummmmm

plush yew Oct 1, 2019, 2:34 PM

#

@inland kettle well you can do both linear and exponential without curves

#

@inland kettle if you multiply the speed by 2, the speed would look like this for example: 1 2 4 8 16 32 64 128 .....

#

so the speed increases more and more

#

you can do the opposite when you get close to your target speed

add points to your points variable when you want it added. When should it be added? Is it when something is shot? How is the person being shot? Do they know who shot them? If they know who shot them then tell that person who shot them to add points

that mushroom look just fine, why do you need to fiddle with the scales? 🙂

#

@plush yew Would prefer to use trees for that rather than mushrooms 😄

#

trees? so last year..

#

don't have an editor in front of me, but it should be in build settings, as a setting called scale, however I would recommend fixing it at export rather than after import

#

not sure which program you use, but they could probably save export settings so you don't have to adjust for every individual mesh that way

📎 unknown.png

plush yew Oct 1, 2019, 6:56 PM

#

could be a bounding box issue, especially with gpu particles you need to set it right

#

haven't used cascade in a while so might be misremembering, but iirc you would let the particles run and capture a good bounding box when you get good amount of spread

#

KK solved my problem

meager copper Oct 1, 2019, 6:57 PM

#

yes i have reset the bounds

#

i was able to get close to what i wanted visually with particles @plush yew , but to get it to work in the game world has proven very difficult.

starting to think maybe particles isnt the way to go

#

📎 unknown.png

meager copper Oct 1, 2019, 7:00 PM

#

i am operating with really big sizes. maybe that works badly with the particles.. i guess I could just scale down everything?

plush yew Oct 1, 2019, 7:02 PM

#

it really depends on what you want, how much control you want etc

#

if cascade doesn't have enough control, you could go for a niagara script, but that might be a bit rough around the edges

#

or you could make your own simple particle system with blueprints/c++ actors to have total control over it

#

I'd say tweaking particles would be the most optimal though, cascade is pretty powerful, plus with some material logic it could be pretty expressive

#

at least, for unreal that is

meager copper Oct 1, 2019, 7:08 PM

#

not sure if cascade isnt giving me enought control. i think what I want is pretty simple. i was able to do it with just canvas in a browser after all 😉

#

there is performance issue with the cpu particles and Lous says there is a bug that affects me with the GPU ones

plush yew Oct 1, 2019, 7:10 PM

#

well canvas is pretty generic, unreal has a pretty tight pipeline for the gpu

#

depending on what you want, niagara probably might be able to give you pretty good amount of control

meager copper Oct 1, 2019, 7:11 PM

#

what do you mean depending? you know what I want by now 😉

plush yew Oct 1, 2019, 7:12 PM

#

there are also other techniques that are more material and mesh based, but again hard to recommend since they can vary heavily on execution

#

well text chat isn't that good at conveying what you want, sometimes even when you are standing side by side it is difficult to articulate 😄

meager copper Oct 1, 2019, 7:13 PM

#

did you look at the link I shared?

plush yew Oct 1, 2019, 7:13 PM

#

but this was more of a niagara thing

#

it is pretty unreal focused thing

#

so getting that amount of control might not be easy if you aren't used to doing things unreal way

#

if you want total control, you could take a look at instanced static mesh component, and animate things via code

#

with instance static mesh component, you just set a mesh, and provide a transform to the component, it renders it efficiently with a single draw call

#

you can than update it every frame etc

#

I am basically trying to make an event where "if you click outside the inventory window, the window closes"

#

📎 unknown.png

#

And yes, I know you can do "onFocusLost" close inventory, but that means that it will also close if I alt-tab, and I don't want that

grim ore Oct 2, 2019, 1:02 AM

#

put another panel/widget in the background and detect a click on it as a handler

#

you can even do that if you are using a canvas panel as the main widget on the viewport and adding other stuff to it, just have it handle clicking on "itself"

plush yew Oct 2, 2019, 1:21 AM

#

nice i see you figured out how to unwrap your mushroom and import it 🙂

#

a blender tip, if you select the top faces and press space then type shade smooth, then those sharp edges where the light reflects will be gone

#

@plush yew

#

@grim ore Found another solution with a bit different approach, but thanks!

#

@plush yew Will try that straight away!

grim ore Oct 2, 2019, 1:26 AM

#

What did you go with @plush yew ?

plush yew Oct 2, 2019, 1:27 AM

#

Decided to instead pause the entire game and make clicks outside the box just bring back focus to it, this way only way of toggling the inventory is with the hotkey (tab)

#

📎 unknown.png

#

@plush yew Cant's seem to make it work, is that in the shading tab?

#

it only starts the video player for me

#

@plush yew in blender ?

#

got it to work, rightclicked then shade smooth

#

yeah space should just give a search box

#

at least with 2.79, i assume this is the same in 2.8 but not sure

#

anyway glad you found it

#

a lot changed in the newest blender

#

i'm used to 2.79 im sticking with it for now

#

also, any idea how to change the size of this thing? I mean, if I import the mushroom directly from blender it's the size of a 100 year old tree

#

lol

#

I mean

#

I know how to change it

#

if you export as fbx there is a scalar iirc, but you can also setup blender so blender units are unreal units

#

but how to have a reference

#

ohhh that's cool

#

okay, last question:

#

📎 unknown.png

#

After scaling it down, how do I bring it back to the bottom centered position? 😂

#

N should open a panel, if its the same as 2.79 lol

#

you should see transform in that panel and a X Y Z median, jsut set that to 0

#

median in edit mode, location in object mode

#

set object mode to 0 if it is not yet

#

after that you can set the medians in edit mode if needed, just select all

#

📎 unknown.png

#

Think the problem is that my midpoint isn't on bottom

sly coyote Oct 2, 2019, 1:37 AM

#

@opal totem you can only temp change the pivot however there is one of the greatest tool I purchased on the marketplace called pivot tool that allows you to change the pivot and bake it permanently into the object without having to go to an external program like blender to do it...I'm not one to advertise anything but felt that it deserved to be mentioned as nothing is more annoying than having to stop your work flow to do something (which unreal engine should ALREADY have built in support for) externally

plush yew Oct 2, 2019, 1:38 AM

#

@plush yew in edit mode, select the middle bottom vertex, snap 3d cursor to that, then go to object mode, then set origin to 3d cursor

#

@plush yew after that just set location to 0 0 0 in object mode

#

then it should be placed perfectly on the ground in the middle

@rotund harness GameInstance

sudden agate Oct 2, 2019, 7:09 AM

@rotund harness you simply need a reference of your actor and make sure your variable type is the same as your actual actor class. this way you can access public methods and fields

rotund harness Oct 2, 2019, 7:11 AM

#

@sudden agate I tried that, but when I created the reference to the actor, I cant set the target to anything, it says ,"editing this value in a class default object is not allowed"

sudden agate Oct 2, 2019, 7:12 AM

#

wtf are you doing. you need to set the reference at runtime

#

you cant set it in the editor

Hey guys, I have an issue that when I import png with transparent background or parts into the engine it doesn't detect alpha channel and it comepletely distorts the imagine, any tips? Thanks in advance

fierce tulip Oct 2, 2019, 8:24 AM

#

try .tga

#

photoshop png + alpha channel doesnt like ue4 and vice versa

ashen cape Oct 2, 2019, 8:24 AM

#

export it as tga?

fierce tulip Oct 2, 2019, 8:24 AM

#

so on import it replaces the alpha to padding

trim trail Oct 2, 2019, 8:26 AM

#

hm.. i think i had some recent issues with png, i think photoshop with default 'save as' doesnt save/add alpha channel, but if you go for 'export file as' (or something like that), you get option to add alpha channel, maybe that could help you?

fierce tulip Oct 2, 2019, 8:26 AM

#

nope, sadly it doesnt

trim trail Oct 2, 2019, 8:27 AM

#

oh well, i guess i was remembering wrongly if it doesnt add alpha channel

ashen cape Oct 2, 2019, 8:28 AM

tga didn't help

#

it just distorts imagine even more

trim trail Oct 2, 2019, 8:28 AM

and bummer with compiling shaders, im thinking how to optimize smoothness when managing assets in ue4, best to do is to have fast cpu and both ue4 project and ddc folders on ssd, anything else?

what screenshots

#

any idea how to change format of the asset to DXT5, that could help

fierce tulip Oct 2, 2019, 8:30 AM

that only works if there is an alpha channel

but photoshops png puts the alpha info in rgb

ashen cape Oct 2, 2019, 8:32 AM

not true, I used photoshop with my previous assets which are also png but for some reason they have different format

DXT5 which shows alpha channel and DXT1

its been a known issue since even udk, apparently it is in the way many tools store their png info, there have been odd examples where it works, in some cases by using the photoshop plugin superpng, but take it from someone who has been around for quite a while, save as tga. png and alpha mess up in ue4

#

occasionally you can have success by saving as "save for web and devices"

ashen cape Oct 2, 2019, 8:40 AM

#

@fierce tulip Yes you are right, I have tried to do it as "save for web" and it worked, still there is little distortion but atleast with alpha channel 😄

fierce tulip Oct 2, 2019, 8:44 AM

#

when I moved to ue4 I tried a long time to keep sticking to png, but the random it working, generally doesnt work gets so much in the way of workflow and being in the zone that I just made two small scripts, save as 32bit tga when it has alpha, save as png in other cases.

Not entirely deprecated. It has its usage. But you don't want to actively draw your UI with it.

You can store your Widget (UMG classes) in it if you want.

@regal mulch yeah that seems the most straightforward way of having a thumbnail right?

The thumbnails of the assets that you see are a lot more complex than that

those thumbnails are editor only

regal mulch Oct 2, 2019, 1:15 PM

they do not exist in packaged builds

I mean, do people pay for such apps often? Has anyone worked on similar projects before?

depends on what you mean by "3D Product Demonstration"

put yourself into the shoes of someone wanted to buy a product, are you going to pull out your smartphone, then download an app, to look at it in 3D?

grim ore Oct 2, 2019, 2:50 PM

@tawdry sierra you will not be able to change the character's inherited components without rewriting your character code in C++ with a custom character. The class they are pointing to in that post is custom code and even then it's not what you wanted since you want to change the inherited class (character)

#

are you using a custom C++ character? if so you could try the same basic code by creating your camera boom (spring arm) then calling AttachToComponent from the MESH onto the spring arm after you have created it and added it to your capsule

crude vessel Oct 2, 2019, 3:04 PM

#

So what's the real perspective on draw calls?

#

Like wouldn't many objects in a level have many draw calls?

wary wave Oct 2, 2019, 3:05 PM

#

potentially, yes

#

most objects will have multiple draw calls

#

the more complex an object (components, materials, etc), the more draw calls..

crude vessel Oct 2, 2019, 3:06 PM

#

Well I mean. My character models may have multiple due to the nature of me wanting to make them modular

next badger Oct 2, 2019, 3:06 PM

#

recent ue4 versions have automatic instancing

crude vessel Oct 2, 2019, 3:06 PM

But I'm wondering could I just compensate by simplifying other aspects of the game?

next badger Oct 2, 2019, 3:07 PM

#

modular characters...you actually can optimize those as well

crude vessel Oct 2, 2019, 3:07 PM

#

Well I saw the mesh combine

#

But okay so hear me out

tawdry sierra Oct 2, 2019, 3:07 PM

#

@grim ore i am trying to edit the c++ code but i cant find the structure that the component order its in.

crude vessel Oct 2, 2019, 3:08 PM

#

Like one of the ideas I'm going to prototype is a character color mask based on a continual hand painted gradient

#

So I want to be able to generate a character with a color vartation based on manipulating that gradient cutoff and levels

#

Which I realize might be a bit heavy , but I'm thinking it's preferable to caching a lot of custom textures, but I guess I'll need to test that out

#

But my goal is to make many unique characters by combining a series of masks in the shader,

#

Other games I saw do something similar but they would bake down the texture

#

I'm just wondering if I had characters who had more complex materials, is that inherently going to kill the performance if I don't go crazy with other details in the level on general

#

Like from a memory standpoint I think a character with a set of shared texture maps that can change in appearance would be better than having to bake out many many megabytes of redundant texture maps

next badger Oct 2, 2019, 3:18 PM

#

Just test it. Look at overall cost, shader complexity etc. Then decide if it's worth it or not.

crude vessel Oct 2, 2019, 3:21 PM

#

Yeah, that's what I'm going to have to do 🤔

#

I'm just. Bit new to ue4 in specific, I'm coming more from the art end of stuff

#

So if course I want to make a very robust character customization process to save labor :)

@grim ore i dont inderstand. Its not an engine content, its from an asset

wary wave Oct 2, 2019, 3:30 PM

#

he doesn't need to edit Character - he can create a new Character and reorder the components in his own constructor

grim ore Oct 2, 2019, 3:30 PM

#

its not re ordering, he wants to take the mesh that comes with character and attach it to a camera boom

#

well spring arm technically

wary wave Oct 2, 2019, 3:31 PM

#

yes? that would be reordering, changing the hierarchy, parenting, whatever you want to call it?

#

you can do that in your own subclass

grim ore Oct 2, 2019, 3:33 PM

#

yep your right, the issues I was having was stupid hot compile and the private class lol I really don't C++ enough to answer these

#

i mean it's super weird lol

#

GetMesh()->SetupAttachment(CameraBoom, USpringArmComponent::SocketName); will get the mesh on the character and attach it to the CameraBoom that was created earlier in the custom character

#

you end up with this https://i.imgur.com/hcsWvdt.png @tawdry sierra which is still odd since I didn't move the camera itself but lol the mesh is now under the spring arm

#

I am curious why the mesh would be on the spring arm tho

so where do i put in the code?

you create a new character subclass

grim ore Oct 2, 2019, 3:36 PM

#

oof. I think you have less C++ experience than me and that's not a good thing in UE4 heh

wary wave Oct 2, 2019, 3:37 PM

#

but if you're totally green to this, it may not be the best idea to start tinkering with this kind of thing

grim ore Oct 2, 2019, 3:37 PM

#

what is the reason you want it like this? having the mesh on the spring arm on the capsule is just going to pull the mesh outside of the capsule and collision will be wonky

tawdry sierra Oct 2, 2019, 3:37 PM

#

i know C, we started learning c++ this year(2nd year of CSE)

#

i need to make it sway

#

the mesh is a weapon

next badger Oct 2, 2019, 3:38 PM

#

ue4 c++ != c++

grim ore Oct 2, 2019, 3:38 PM

#

for the example above I just make a new C++ Character then added that line of code at the end of the constructor

#

well a cool side effect of doing it this way is you can enable camera lag on the spring arm and it looks weird heh

#

feels like moving on ice

tawdry sierra Oct 2, 2019, 3:41 PM

#

can you think of a better way to implement weapon sway?

#

i looked it up on youtube but it didnt work right

grim ore Oct 2, 2019, 3:42 PM

#

I would assume it would be an animation but I am not an artist so nope I can't think of a better way lol

#

ahd weapon sway != what I think it is lol, so yeah weapon sway is lag when turning?

so another option btw would have been to just not use the mesh that came with the character, just keep it empty and hidden, then add in your spring arm and weapon mesh as children so you don't have to worry about all this weird c++ stuff

#

yep https://youtu.be/71StGGtAyMw

i tried adding the spring arm as a parent of the camera

#

but...

#

it does this

#

ive set the length of the spring arm to 0 aswell

#

how to i fix this?

grim ore Oct 2, 2019, 3:51 PM

#

it's not going to be perfect and I cant see a problem there

tawdry sierra Oct 2, 2019, 3:53 PM

#

it should look like this when i look down

📎 Capture12321321.PNG

#

it behaves differently

grim ore Oct 2, 2019, 3:54 PM

#

i would assume the arms and gun are not moving together in this case? since you have 2 meshes and only one is on a spring arm?

#

if you noticed in the other example videos they didnt show anything more than 1 mesh being swayed

Anyone has a good tutorial Youtube channel for Unreal? 🤔

uncut osprey Oct 2, 2019, 3:59 PM

#

I'm just going through the in-editor guides first

#

I find a lot of tute videos are "How to make this exact thing" but don't describe the fundamentals much

#

but i cant parent the spring arm? How do i do that

grim ore Oct 2, 2019, 4:05 PM

#

you can see exactly what I did using a clean FPS BP template. you are using the FPS C++ template?

#

if so just ignore the mesh that comes with it and make the same hierarchy from the camera down

#

you can actually see that is exactly what it does in that screenshot lol

i have a question. The Monthly Free stuff, is only for that month and you can use it throughout that month or is it permanent? 🤔

snow thorn Oct 2, 2019, 4:13 PM

#

@visual pawn it's permanent for you if you get it this month

grim ore Oct 2, 2019, 4:13 PM

#

anything you add to your account, free or paid, is yours for life or until it gets removed for some other reason.

visual pawn Oct 2, 2019, 4:13 PM

#

oh alright 😄 cool

#

gonna keep a close eye on them then

#

alright, downloading Unreal....here we go 😂
A lot of sweat and tears incoming !

serene birch Oct 2, 2019, 4:21 PM

#

some of the monthly free stuff is permanently free, you can get it later

visual pawn Oct 2, 2019, 4:22 PM

#

yup i saw that, was mostly curious about the Monthly Free 😅

@gleaming narwhal could you guys please answer these questions during tomorrow's stream https://forums.unrealengine.com/unreal-engine/events/1670169-unreal-engine-livestream-tech-art-with-chris-murphy-october-3-live-from-hq?p=1670201#post1670201 ?

Epic Evangelist Chris Murphy returns to share his latest adventures with shaders, procedural landscapes, and fully scaleable buildings. Follow

#

Last time I posted questions in the forum and they were totally ignored :/

gleaming narwhal Oct 2, 2019, 4:26 PM

#

@vale silo Ignored and not asked are two different things! I always let the guests know about the questions on the forum announcement, and if they can/want to answer them they get asked

#

I don't think Chris can talk about the future, but procedural landscapes based on a height map is what he'll be demonstrating

grim ore Oct 2, 2019, 4:32 PM

holy crap whats coming in .26? isnt that like a year away at this point?

wary wave Oct 2, 2019, 4:33 PM

#

define "procedural"?

grim ore Oct 2, 2019, 4:33 PM

#

I think you give them too much credit about that far in the future heh

why does downloading kite demo for 4.23 take 24GB when I already have the 4.21 version in vault cache? Why not only send the delta (the engine already has a block delta encoding like rsync as part of the patching system)?

wary wave Oct 2, 2019, 4:36 PM

#

it's not really a delta because the assets aren't strictly the same

slow hearth Oct 2, 2019, 4:36 PM

#

large binary chunks of them are, which would compress fine

#

I'll look at what size rsync takes to sync between a 4.21 and 4.23 download of it, I would guess a few hundred megabytes or something

So I have an Actor with a skeletal Mesh and a character with the same skeletal Mesh. But somehow, both objects have a different hitbox. Also, when I'm behind the character and shoot between its legs, it says I hit it. When I'm in front of the character and shoot between his legs into the exact same position, it says no hit. I know its hard to solve something without screenshots, but has anybody experienced something similar. Thanks :).

wary wave Oct 2, 2019, 4:37 PM

#

but you can get around it anyway by putting the assets into a 4.21 project and migrating what you want across

#

also the 4.23 version needs to be able to just shift the assets into the directory you want

slow hearth Oct 2, 2019, 4:37 PM

#

yeah, but can just never be sure they havne't made fixes with the 4.23 release because they don't seem to do changelogs

wary wave Oct 2, 2019, 4:38 PM

#

true enough - but I wouldn't expect they've been touched much after they were released

#

just had whatever additional version data diddled automatically

slow hearth Oct 2, 2019, 4:38 PM

I've seen shootergame occasionally modify the uassets for various purposes
