To my question from Earlier, after playing around a bit i figured out the issue. Steam changed the way the Builder looks at content root in the update from yesterday on SteamCMD. the App_Build is now what MUST have the directory set for ContentRoot.

If I execute logic on event tick, will that logic definitely all get executed before the next tick?
torn herald
Yeah if it isn't somehow running as async. It can't do another tick function call until it has finished.

@plush yew I think you can develop in 4.25+ and rest assured it will work in UE5, but some things might get deprecated IDK, I wouldn't worry too much. I have 3 years of work invested in a game now in 4.25 and I feel pretty safe that it will continue to work in UE5

@queen wasp If you're not seeing any difference between sync and async, sounds like something isn't right there
queen wasp
@fervent sigil Yeah. also struggle with a lot of hiccups in playing my game here, framerates down to 11-15 fps haha, well I know I have a job optimizing ahead of me π I did have it running at around 50fps steady before but have added new things.... Got to find the bottlenecks..
But yeah, async should've in how I gather it is supposed to work, give the main thread enough room to at least run the Niagara GPU particles
The game is all blueprints sigh and I am a c++ programmer with decades of programming experience, I just fell for blueprints 3-4 years ago. Sort of hoping nativization will help, that is if I can manage to package the thing.
Sort of nuts to make a multiplayer RTS in all blueprints maybe? I keep trying, love blueprints.

hey im trying to import this png
into unreal
but when i do
it does some weird shit
..what??
it looks like its inverting it?
but also where did the outline go lol
oh i see
queen wasp
@brazen crow if you look in the editor at images with alpha, the color of the alpha pixel is shown instead of transparent, you can on the top-left choose which channels to display
So when used in-game it might be fine
brazen crow
that is in game
i think i see what u mean, its just changing the background from clear to.. black
queen wasp
using slate/umg?
brazen crow
but why
sterile tulip
Good tutorials for learning and understanding blueprint nodes?
queen wasp
Yup, If you click "view" in the top left corner and uncheck all but the alpha, it should show what is transparent, but if you get no transparency in-game I guess it depends how you're using the image
queen wasp
Maybe you forgot to check "transparency" in export of the PNG from f.ex. photoshop?
queen wasp
Yeah.. hmm.. if it is an 8 bit PNG and of some reason it doesn't import the alpha. Could try convert it to PNG24
In that editor if the alpha imports correctly you should've gotten a grid pattern where it is transparent

ok so i am trying to figure out how to make a spinning portal effect with my material and i am not sure how to go about that. I have tried using a rotator, which does work, but the problem is i have to scale the texture down because the mesh the material is on is small.
This is what ends up happening. Any ideas?

How do I disable collision on painted static meshes that I painted onto my landscape?
plush yew
Hello, i am doing a skeletal mesh switch at runtime using 'set skeletal mesh', the problem is there is a slight jitter just before the meshes swap out. It's not like the pose changes as both meshes are almost identical, just that the replacement mesh animates extremely for a frame and then snaps back to its rest pose. Can anyone think of any possible causes and ways to smooth out the transition? Am willing to go into more detail if needed.

hey guys. ive been on this problem all day. so i have a scroll box widget with child buttons inside of it. im making a game with gamepad input only. i can move my focus up and down the buttons in the scroll bar normally. but when i try to click on the buttons, they don't activate. i either have to click on them with my mouse first or move the selection all the way to the top or bottom and only then can i click the buttons with the gamepad
ive gone through my code over and over. i tried to make it based off of some tutorials i found on Ryan Laley's youtube channel. but i cant find the problem. most of the code is practically copied and pasted. i just modified it a bit to fit my menu.

I want my actor to store a render target so that each instance can write to its own individual texture. I thought this would be simple, just add a render target variable. That would just be a reference to a render target, though, not an actual render target. Any thoughts?
Because you haven't set anything to preview.

@silk lintel yeah, I fixed it by removing the 0 constant
dawn bloom
how do you set an object's direction?
like which way is forward for the object, right for the object
dawn bloom
is that what you use to set it up in the viewport?
silk lintel
@dawn bloom Technically there is no real 'forward' or 'right', but the default 'forward' axis for an actor is x and the default 'right' axis for an actor is y, both being positive.
silk lintel
@dawn bloom I think you might be able to do that in editor settings, but I'm not 100% sure. You can't rotate the viewport, no.
silk lintel
I'm not sure what you're talking about
dawn bloom
austere bay
You mean, your mesh isn't correct direction?
silk lintel
No, that's the rotation gizmo
dawn bloom
@austere bay I think thats my problem?
silk lintel
Wait, show it in transform
austere bay
Okay, well, then just rotate it. Blue is Z axis, green is Y axis, red is X axis.
But beware, in UE4 Y is forward
and Z is up
silk lintel
If your mesh isn't in the correct direction you can't rotate it and change the axis
That makes no sense
dawn bloom
hmm why not
austere bay
And if you're really bothered by it, go to Blender or Maya and change your mesh's direction π
silk lintel
Because that's editor code, not something that changes per mesh...
I'm not sure what the problem is
dawn bloom
hmm no I think I understand now
I don't need to change the vector
or like the mesh direction
silk lintel
If it's something as simple as the mesh not facing the correct direction, you'll have to fix that in blender/maya like @austere bay and reimport or fix that in import build settings
dawn bloom
thanks!
austere bay
How can I scale my canvas to screen size?
silk lintel
@austere bay Do you mean in a widget blueprint?
austere bay
Yeah. Basically a placement of my image changes based on screen (viewport) scale.
In Unity I can set the entire canvas to scale with screen size, can I do something similar here?
silk lintel
@austere bay The outer-most element of a widget blueprint will always be the full size of that widget blueprint. This is the canvas by default, but you can set it to anything. When a widget blueprint is directly added to the viewport (without its scale being altered by, for instance, making it an element of another widget blueprint) the widget blueprint will always be the same as the viewport scale. In other words, if you add an unaltered widget blueprint to the viewport without changing scaling, the canvas size be the same as viewport size. If you want an image to scale to screen size then either make it the outer most element in the widget blueprint, set it to fill horizontally and vertically, or manually change the scale (but I would never suggest that).
subtle sage
Hey uhm.. Can anyone tell me where the hell I can find a vertex position/transform node in the material editor?
or geometry node.. something
silk lintel
@subtle sage World Position
silk lintel
@subtle sage Wait, let me double check
@subtle sage I don't think there's any way to get vertex position currently, but world position would be the closest option
austere bay
Setting my widget to this seems to be working
silk lintel
you can use vertex painting
but that's in editor, not material editor
@austere bay That's the anchor, which basically controls where the center points of the widget are located. If you want an image to fully cover the screen you should set anchor to full (the square in the bottom right) and set alignment to fill (the far right) in horizontal and vertical.
austere bay
Nah, I want the image to scale properly.
silk lintel
Wait
Are you asking how to uniformly scale the image?
So that it will keep aspect ratio?
austere bay
Yes. So regardless if I'll play in 800x600 or 1920x1080 it will always stay in bottom right hand corner.
silk lintel
Ohhhh
Sorry, I misunderstood the question. There are two good options. One is to a scale box widget and set it to horizontal right and vertical fill (like you have it), then put the image inside the scale box. You can also set the horizontal alignment on the scale box to right. Another option is to use a horizontal or vertical box, but if you only have one element (the image), then a scale box would probably be your best bet.
austere bay
So what I did is okay?
silk lintel
Well, I'd recommend putting the image in a scale box so that it keeps the same size. That's what you want, right?
Then you set the anchoring the way you have it on the scale box rather than the image
austere bay
You mean this, right?
Sorry, I am unfamiliar with UE4 terminology so trying to figure out what a "scale box" is.
silk lintel
No, the way you had it. The anchors on the bottom and right are for fill. You want the scale box to fill horizontally but not vertically, and you want it to snap to the right. You should use the one right under where you marked.
silk lintel
@austere bay The scale box is a widget you can find in the palette and drag-and-drop into whatever widget blueprint you're working on

safe dock
@plush yew i currently have a mass of 50 kg and a friction of 5000
The thing is the ball is still running faster than me and it no longer bounces
plush yew
well footballs don't bounce really do they
increase friction more
Also your surface might need some friction
safe dock
Footballs bounce a bit... Don't they?
plush yew
A little yeah
But seems like your problem now is just friction. Whether the ball bounces depends on the point of contact, you want it to be just below the centre probably

@safe dock for physics to work effectively, both objects that collide have to be simulating. If one is and one isnt, the one that's not will bounce off the one that is

I'm making a game with conveyor belts and lots of items. I have a system where every static mesh / item is grouped in its corresponding HISM and just dynamically works to be added / removed / used etc. I'm wondering what the most performant way to make them move on a conveyor would be. Some options would be:
- Keep system as is and let the conveyor tell the HISM transforms to move (I've done this in a test but ran into performance problems at CPU level at like 600+ items)
- Move items that are being handled by conveyor belts into their separate HISM local to the conveyor belt, then update their transform less frequently depending on distance to the player. This means I would probably have a max length for a conveyor belt (currently unlimited), so that I can piece it up. But it sounds like a pain to get working without visual glitches when an item moves from one conveyor belt end to the start of another (which would visually look like the same belt)
- ?

also you can just build lighting by pressing the "build" button, or you can scroll the options on "build" and pick "lighting", but in my experience, casting shadows really fucks up the way the objects look

select the light source in your level

it will give that error when you are building lighting as well, perhaps you are building and it's not done?

look for the "cast shadows" box there in your light source on your level in the "details" tab when you select it and make sure that "cast shadows" box is unchecked

Is there any alternative to structs? Preferably a BP solution but honestly I'll migrate to cpp if there's a better option.
I mostly use structs for data like game items, player/npc stats etc
I fear if I keep going this way the whole project will go to hell at some point.
Also - if there's an option for data management like that but with inheritance or composition I'd love to know

@plush yew @grim ore
What would you use for Item / Stat / misc data instead of structs? I've been looking at class and object but it's not obvious how they can be configured like in a data table
sweet flume
@alpine laurel youtube animated materials with flipbooks
there is a video showing how to do it that litterally makes a spinning portal
Its pretty basic make a texture with your sprite animations in a sheet, use it as a source texture, in the material, feed it into a flipbook node, and out to your material... adjust as needed
sweet flume
the video explains the gotchas a lot better then what i did, but unreal engine handles the pipe line for animated materials pretty well imho
pulsar flume
If you don't mind sharing, how do you handle different item types that have different properties?
Do you cram them all in the same struct like me? π
alpine laurel
Its pretty basic make a texture with your sprite animations in a sheet, use it as a source texture, in the material, feed it into a flipbook node, and out to your material... adjust as needed
@sweet flume and its one image, not multiple
sweet flume
@pulsar flume you could make a base item class, inherit from it for each class, and hold the classes ID in an Enum for drop tables.
@alpine laurel you have to use a sprite sheet for an animated material in unreal engine.
grim ore
@pulsar flume there isnt much you can substitute a struct for if you need it π¦ data table for data that you dont need to change and imported from an external file and beyond that probably C++ backing classes for data so you dont have this issue
alpine laurel
i just need to spin the texture. is there another way?
sweet flume
@ripe meteor it moves your items from data based items to more object based which many would argue bad (even myself in some cases) but it would by pass the struct
@alpine laurel no.. you need to make a sprite sheet with each frame of the texture
there are other ways but they are very resource intensive and arent the "right" way to do it
pulsar flume
Yeah, but it still doesn't solve the main issue which is the lack of inheritance. Shame
sweet flume
@grim ore ever think about doing a video on "BindJumpApex" event? Some of us would reallllyyyy love to see it π
@pulsar flume why not just make a base item class and create a blueprint for each item?
then you could easy just use a select statement for drop tables and stuff
Ok so in item design for games there are two main ideals, one is what is called the "spec oracle idea" which basically says all items should only be data that is fed into an item class that constructs the item, and adding new items is done by adding new data the item class understands
pulsar flume
That's the way I'm leaning towards
sweet flume
then there is the "items are living idea" which basically says each item should be its own class and should be instanced in the world or inventory or whatever when its "spawned or exists"
Each method has its up and downs
sweet flume
for instance in the spec oracle design your item class has to know what the data values are given to it, this creates less flexbility if you want to make unique items it causes your base class to have logic for only a few items in your game
but it makes adding items extremely easy
with the second one items are living, so each of them can run their own code, which makes making turely unique and customizable weapons easy at the expensive of requiring more resources for your overall item system
THe more actiony you want your combat system to be the more you will want to lean on the ideal of living items.
pulsar flume
The main issue I see with the 2nd method is that items have to be "spawned" to access their data
grim ore
@sweet flume it looks like it's a normal event in the character you can bind to, what is the issue with using it?
sweet flume
@grim ore I dont know just cant seem to get it to work, or maybe i expect it to work differently, i am trying to use it for animations to get the peak jump to change animation to falling, but it seems to just never fire off
pulsar flume
THe more actiony you want your combat system to be the more you will want to lean on the ideal of living items.
@sweet flume in this game specifically I'm going for a simple click to attack. Most gameplay revolves around building and crafting a ton of different items
Which is why I'd rather avoid creating a bp for every item
sweet flume
@pulsar flume if there is a lot of item construction it gets hard with spec orcle system.
pulsar flume
They're all very similar
sweet flume
Also you dont have to instance the class to check its values unless you expect them to be different from the class defaults you set
and if they are different then defaults should already be instanced
pulsar flume
I'll have to look into it. I just feel like hundreds of lines in a json -> data table is easier to handle than hundreds of bp files
grim ore
@sweet flume I dont think its really going to give what you want, it basically triggers the event when the "Falling" movement mode triggers but you can already check for that in an anim bp if using one. If not, this screenshot is the basics of it (this is in the third person BP). The key is you have to activate the notify apex boolean whenever you want it to be usable and whenever it fires it disables itself until you enable it again. Since I only want it to fire when jumping I enable it when I jump (if I did not, and it was always on, it would trigger when walking off a ledge since that triggers "falling)
sweet flume
ahhhhhhhh
yeah i already got a working solution
just thought the apex thing was the "right way"
I just was not understanding the way it worked
grim ore
I could see it being useful if you wanted to do something like check the distance to the ground when you hit the apex and then XXXX
sweet flume
yeah i see
I am just checking velocity z value right now to know if the player is going up or falling down
grim ore
or even maybe allow some custom code to fire off like "I hit the apex, now we want to enable gliding mode"
yep that makes sense for what you need
sweet flume
@pulsar flume there are lots of good white papers written up about coding and managing game item systems. Lots of really good coders from tons of great games have really put a lot of brain power into this stuff
grim ore
lots of the code is weird since its like super custom case lol
sweet flume
yeah gliding mode is a great idea case for that
pulsar flume
I'll have to read up then. Thanks!!

Have a problem with a material setup, following this video https://www.youtube.com/watch?v=yCRzOdo4b68 about 3:50 into it
where he copy some nodes from the gold material and use in the landscape material setup, he get variation in the grass, I gets only silver
hushed cedar
@ancient fiber can you send a screenshot of your setup

can someone please tell me what is that "3" node?

That would just be a vector/constant 3 node, 3 values or a color without Alpha

Hi anybody good with Collision?
Ive set my actors static meshes to Block all, as well a my player meshes to block all, but still they dont block
hushed cedar
@ancient fiber ok try this, set the bool to true but delete the \content\ from the path
hushed cedar
fixed?
hushed cedar
cool, happy to helpπ
crisp thicket
both actors collision is set to "block all"
for tghe corresponding static meshes and skeletal mesh
but still my player mesh goes through each wall
alpine laurel
so in my fps i have set up my rifle to attach to the right hand via a socket on begin play in my character. the arms are "static" and are just in one position, but will move for animations like reloading.
How would i go about making it so the arms would change if i were to say equip a pistol?
hushed cedar
@crisp thicket when playing in the editor open the console with ` key and type show Collision and check the collision for both the wall and player
crisp thicket
you can see the collision in the video I took
i think I have to enable simple or complex collision for the walls
stay tuned
hushed cedar
the video is low quality, is the capsule collision with the player?
crisp thicket
yes but Im using the static meshes collision
hushed cedar
@alpine laurel if i understood correctly, you have to set up an state machine for that
crisp thicket
the capsule Component doesnt move
hybrid light
why am I getting this error every time
grand walrus
hey, everyone.
sorry for the minute long video, but this is bugging me and I just can't find the cause after toying around with it.
I have a melee combat system set up that is a component, the AI and player both use the same exact combat input system.
The player can hit the AI seemingly 100% of the time and get a hit, meaning that contact was made, an animation fires, and HP is lost to the AI.
The AI can hit the player fairly regularly and get a hit, but even as the exec fires through my code, the animation doesn't always play on the player, even if HP is lost (contact was made).
Here is a video demonstrating what happens, and here is a big picture with a step by step of what happens in the combat system (the part that is having trouble).
https://streamable.com/ac1lvw
crisp thicket
when I type "show collision" in the console, my walls actor has no collision
grand walrus
The trace gets performed on an event tick basis, btw.
It's gated by a branch that is triggered by an anim notify state.
crisp thicket
how do I check if im using rigid body physics
hushed cedar
if you didn't set it up then you're not
crisp thicket
what is it
hushed cedar
try moving the capsule with the player
alpine laurel
@alpine laurel if i understood correctly, you have to set up an state machine for that
@hushed cedar yeah i just figured that out. would it be more effective if i attached the pistol to seperate arms and switched or just keep using a socket to spawn the weapons?
hushed cedar
socket is fine
crisp thicket
still doesnt work
alpine laurel
ok. im jsut worried that while the socket works fine for my rifle, what if when i switch and the hands go into the position for pistol, but the pistol ends up out of alignment. i would have to move the socket, but that would effect the rifle. what would i do in that situation
hushed cedar
@alpine laurel there is a tutorial series about making fps games in ue4 on Youtube
grand walrus
can't you make 2 sockets?
hushed cedar
alpine laurel
yeah i have watched that tutorial. its the one i used, but it only covers rifles and he doesnt move the sockets or anything for it
hushed cedar
this is what i watched
grand walrus
idk what you're trying to do, but if you can use sockets for rifle
why not just have more sockets for pistol
or
do a bit of math to move the socket manually on a switch based on what weapon you're holding
so if the alignment is messed up while using pistol
just offset in bp only while pistol is equipped
if that makes sense
hushed cedar
@grand walrus what are the errors about simulating physics? is it irrelevant to the player?
alpine laurel
im not that good yet. so im not really sure how i would do that
grand walrus
uhm, you know, i don't know, let me take a look
it should be irrelevant, because whatever it is it is applying to both my player and the AI
hushed cedar
and also is the AI also using the masculine option you changed at the beginning ?
grand walrus
I think it has to do with where I messed with some CCD setting
it's not, but that is also irrelevant, there are no overlay checks
i could be in any overlay, default overlay, which is what the AI is in
i am making a detailed reddit post about it with a huge picture list of all the inner workings of the code, will link it when done if you need more info
hushed cedar
maybe try to understand why the AI works and see what's different between them
grand walrus
they both use the same animBP and BP, as well as combat BP
hushed cedar
maybe the player controller is preventing something to trigger but the AI isn't
grand walrus
it's weird, too, because sometimes the hit reaction works on the player
lemme check
nope, player controller only does widget / input stuff
and in my case, actually doesn't even handle combat input
only handles ui inputs for the ALS system i use
hushed cedar
your only hope is to fix the errors that you know what they are and see what remains
@alpine laurel i just remembered, you can check out Advanced Locomotion System V4 to learn how it handles guns and it's animations
alpine laurel
thanks
hushed cedar

yep you created a C++ version of the project then. So either remove the lines from the cpp file or if you wanted BP project start over

grim ore
don't have to hack anything, just set the default maps and mode -> game mode -> default HUD to the blank HUD class
thick knoll
my selected gamemode stuff is greyed out, not seen that before

I painted alot of foliage and it got laggy, and then I removed the foliage but its still laggy where I had the foliage before? Why is that?
grim ore
@quiet finch the game mode and the controller have events that fire off when a player is trying to spawn or being possessed by a controller
otherwise the begin play for the player can be used
grim juniper
@vapid bronze What MathewW said. Also, the reason the door shadow looks more accurate before building is because it's using dynamic shadows as a preview compared to the baked lightmap textures from afterwards

then use the game mode

i have a problem with a media texture material
vapid bronze
autumn grail
the texture is correct but the material is white
vapid bronze
The light went AROUND the open door after building without the wall/substraction doorhole
grim ore
@vapid bronze click on the mesh you want to adjust the lightmap on and search for lightmap, there is a checbox to override the default lightmap resolution and set it to something higher that is power of 2. so if its like 32 by default try 64 or 128
autumn grail
i imported a mp4 video , and created a media from it , and created a media texture from it , and created a material from it
only the material is full white
grim ore
are you playing back the item on the material? playing the media
its going to be white as you have no media playing, when you play it the texture should update

It work
i just checked the auto clear checkbox

it explains how to play it anywhere, the bottom part tells you what to do

you need to open the media source so it will auto play, or you need to open it and tell it to play

rare sorrel
Hi all,
I'm still trying to learn UE4 and I have question related to my first project. I've been trying to fix my landscape material for 2 weeks. I have 15 blended material functions and all my textures are set to Shared:Wrap. I'm using feature switch as well. In stats texture samplers count is shown as 2/16. Landscape material works as intended in SM5 preview.
First problem I've faced is when I try to paint 3 different layers in the same landscape component. In ES3.1 preview those components have three or more layers turns to grey and stay like that even after compling shaders. I had read that it's fix to maximum of 3 in the forums. But in my case I can paint each component with more than 2 different layers. I want to apply grass, sand and water materials in the same tile. After I decided to go along with this problem because I couldn't find the solution. I thought that I already can apply each material without using 3 of them in the same tile and use some foilage to compensate the missing grass material in coastal areas in the world later on.
But here is the second problem comes. I created new dummy level and new dummy landscape material but now with 4 layers in order not to touch anything already in the project. It didn't work at all. Now even with only grass material applied to whole landscape, everything is shown as grey in ES3.1 preview. Then I opened my old level to see if it's still working. The whole level is now grey in android preview even though I didn't changed anything including landscape material and its material functions.
Any idea how can I solve these two issues? thank you all in advance for your time and sorry for this long post.

thorn dew
@rare sorrel Even on PC it does not perform well when the landscape has more than 5 different textures. You look at a texture performance and it starts getting pretty red. For maximum performance on android I'd say stick to 3 at most or better 1. To get more variation add in different geometry with a different texture on that geometry above the landscape. Some rocks and such can also change things up. Got to get creative when doing landscape design and keep it performant.
plush yew
i was just wondering if any of you have made 2d games using unreal
(stupid question , but just curious)

@rare sorrel @lucid grove This video might help both of you. https://youtu.be/gMKjIZMPJ0Q
@plush yew I played with 2D elements in Unreal. It works pretty well. Didn't have a ton of sprites though so don't know how it would work with complex things.
plush yew
a lot of people seem to be against the idea of using unreal for 2d (obviosly 2d isnt the focus of unreal) but its good to know that 2d elements are nice in unreal
thorn dew
Unity people want to think their program is better, so they say it's better for mobile and 2d. It does have some 2d tools that unreal does not. Nothing I think is super needed. For mobile I saw a comparison between two people that knew their engine really well. Unreal was slightly faster. Not much though. They are both great for mobile.

Does anyone know how to get something with velocity to stop right when it overlaps an object? I got something with velocity and even though I say on overlap set velocity to zero it still penetrates a bit between ticks before stopping.
What I'm actually trying to do is get something with velocity to smoothly avoid a circle. If anyone knows how to do that it would be best.
I had an idea. Maybe radial force?
I'm setting the velocity of the sphere every tick so the radial force doesn't seem to be working.

Hello guys, I imported one shop model that was made by 3d artist and when I import it and try to enter inside of it through the empty space for the door I can't enter-how I can fix this problem? I tried to play with the collusion settings, I added box collusion, used simple collusion as complex, used complex as simple and it stil doesn't work, my 3d artist sent me this: https://www.youtube.com/watch?v=3QwbhZ9dlL4
When I import the mesh I disabled the option "auto generate collusion" but unfortunatelly again doesn't work
will be happy if you can help me fixing it

I could be that it's compiling shaders. Can take a while.

I have noticed that others have faced this problem but there is no clear solution. I was wondering if anyone here can shed some light
@worldly rose thank you. it doesnt move forward at all even after an hour or more.
I have a RTX 2070 Super with latest drivers.
it is not using GPU at all at this stage anyway.

I usually start the editor from a terminal, then I can see the log output directly and that gives more information on what it's doing and what it may have stopped on.

Are normal maps just adding brightness and darkness to the texture?
To create fake shadows?
plush yew
can someone help me ?

@sterile tulip Normal maps don't change the texture. You can imagine it as if they change the angle of the light that gets reflected from the surface. The angle between the view direction and the surface normal, as well as the angle between the light direction and the surface normal are two factors that change the final color of an object. The normal map changes the surface normal.

I just wonder if it is Unreal or the computer that is struggling with 8k Landscape?
with 8K have have all kinds of graphics problem, with 4k these problems more or less dissapear
shell hamlet
it might be
I have a i7 coffee lake, 16 GB ram, Graphics card is a Nvidia GFX 2070 with 8Gb Ram
that area there is not updating
is there a way of force it to update?
@sterile tulip so no, this can't be the pc, I am down to 2k

How do you add these small line details to make it look more realistic/mountainy?
shell hamlet
that is the greyscale
sterile tulip
Do you mean heightmap?
shell hamlet
yes
shell hamlet
there are many methods to make height maps
terrain.party is a source for maps
these can be imported in Unreal
sterile tulip
Do you add the heightmap on your brush or directly when creating the landscape?
shell hamlet
no
sterile tulip
Because when I do heightmap the resolution is low
I have 8k landscape
So I would need a 8k heightmap
shell hamlet
I am not sure if you need a 8k heightmap
yes you are right, you need a 8K heightmap

So I am very new to ue and I have a question about arrays. I am spawning a bunch of the same actors and I want to be able to manipulate the UI on the actors individually and change variables on each separately. Right now I am using get all actors of class just to make the UI work but I really want to get basically an ItemID from an array so I can manipulate just that individual actor I am clicking on. Sorry if this isn't correct terminology!

@subtle timber all Unreal textures can be used since they are PBR
all major graphics packages can use PBR textures
subtle timber
@shell hamlet I want to define my Material in a other graphic package so when I import it into Unreal I don't have to build my Materials again because they are already defined and asigned trough USD

Is tessellation very expensive or could it be used in games?

is there a way to allow for the light to pass through a static mesh ?
I have a ceiling, I want the natural light to pass through it, while the mesh retains its visibility
shell hamlet
@subtle timber the unreal native material, only unreal can use, all the rest is just textures for the PBR workflow
subtle timber
@subtle timber the unreal native material, only unreal can use, all the rest is just textures for the PBR workflow
@shell hamlet Yes I know but maybe there is a Unreal USD Material which can be defind in USD and than be read out on import by unreal to genarate a Material with all proper inputs defined in USD
shell hamlet
doubt that very much
there might be a live plugin for USD that can read the material in Unreal
subtle timber
unreal can read the USD Material but this has only a really rough set of inputs. and Unreal can not interprte all of them. The only one which are reliable are the Albedo and the Normal map.
shell hamlet
have you read this: https://docs.unrealengine.com/en-US/Engine/Content/USDinUE4/index.html
@tight prawn wouldn't you need a translucent material for that ?
subtle timber
have you read this: https://docs.unrealengine.com/en-US/Engine/Content/USDinUE4/index.html
@shell hamlet many times now yes

thanks for yout help one last Question which kind of an input does the Roughness take? ist it a 3float or a 1float?
can not find the answer to this question in the docs

Hello

How would you guys go about making an NPC pick a target? Should this be done in the character blueprint or in a behaviour tree Service?
Doing a MultiSphereTrace in a BT service seems like it would allow reusing the service for multiple types of NPCs (without having them all inherit from a master NPC blueprint), but I've seen people online advice against using traces where components with begin/end overlap events would suffice.

Thanks! AI Perception is probably the way to go. I'll look into it.

Other than that, it seems to be working well enough

hello guys, probably pretty simple, I just can't figure it out. How can I make a light rotate colours constantly? Change colours, like disco lights or smth.
uneven raven
@wind gate my noob solution in the past has been to just stack a bunch of lights in the same place and have them turn on/off in a sequence lol. I'm 100% sure there is a better way though
late verge
hey everyone! with a cine camera, how can i go about changing the shape of a bokeh to a more anamorphic style?
grim ore
@wind gate you would expose the color parameter in the material and then a blueprint can change it, alternately you can put a texture with colors in it and change the uv coords to swap between fixed colors. alternately you could look at using something like th UV coords themselves and drive the color from that. a sin or time or both node can be used in a material to make it stand alone and change without using an external BP. tons of ways
uh...
why not test that?
like your question is literally something you can determine by testing
and the answer to both is maybe depending on your code
strong schooner
Are alembic costly to run in a scene?
grim ore
@wind gate I just realized you asked about lights directly and not a material lol, same concept tho. A blueprint can talk to the light and change it color randomly or in a fixed set of colors thru like a timeline
wind gate
thanks @grim ore , thing is that if I got with material it doesnt really emit anu lightning. I know, I can set "use emissive for static" but what I am looking for is more like a directional light change the color of the light it projects. In the past I did a function for flickering the light, I was trying to do the same for the change color but i cant figure it out
Nice synchronization @grim ore haha let me check what you wrote
Hmm. what you say makes sense. I will try it out. Been a while since I messed with timeline. I am thinking of using a sine for like the RGB table or smth. Will go with trial and error I guess. Thank you for the suggestion!
grim ore
it just depends on what you want in terms of colors and timing.
like does it pick from a color table every X seconds, or is it just rotating along a spectrum, or etc.
like this randomly picks a color every second
but you could make it transition smoothly between colors with a timeline and lerp. If you needed a fixed set of colors you could just program them in a vector track and change the color like that
wind gate
that's a great idea! thanks!

Is there no event dispatcher for when the Max Age expires for perception? Should I be checking for updates in the tick event or something? I've set the Max Age for my AIController's Sight to 5 and was expecting OnPerceptionUpdated to be called again 5 seconds after moving out of the Lose Sight Radius, but it never happens.

Ok no problem, you're just treating me like a scammer, so I wanted to make it clear I am not. I will not ask you further.
Didn't mean to scare the guy, just mentioned that I wanted a photo ID to join my project

@obsidian wasp I'm counting the age and handling its expiration in my own function that gets called every 0.5 second instead of relying on Max Age, as I never figured out how to make Max Age work the way I want

how can I edit inherited content?

Okay I know this is a dumb question, but I keep having issues opening levels. I've tried opening different viewports but that doesn't help, any suggestions?
grim ore
@golden niche you cant, its part of the parent so you would have to edit the parent. and i guess it depends on what you mean edit. You can change properties
grim ore
is that attaching the inherited component?
