i don't mind if it's convoluted so long as it's a system i could set up and reuse for multiple materials ^^

storm venture Sep 21, 2020, 10:13 PM

#

@warped tangle Yes! Nice! Your math is perfect.
And now I know how to convert a parameter to world location:

📎 unknown.png

#

using the scene component seems like such a hack, i love this solution 😛

grim ore Sep 21, 2020, 10:15 PM

#

its like saying "lets figure out where the wheels are on the car based on an offset from the center of the car instead of using the actual location of the tires"

#

a scene component exists to literally be a transform in the project

storm venture Sep 21, 2020, 10:16 PM

#

while the scene component is like "lets figure out where the wheels are by placing hub caps on them and figuring out where the hub caps are"

#

i can dig scene components usually but idk about this time

#

i admit the scene component works great

grim ore Sep 21, 2020, 10:16 PM

to each their own 🙂

storm venture Sep 21, 2020, 10:16 PM

but yeah, this particular instance needed to avoid them for a few reasons

Hello, i have a problem for coordinate my displacement map on my mesh

warped tangle Sep 21, 2020, 10:19 PM

#

For leaning purposes, yes, it works. For practical purposes, I am completely in Mathews camp. Use the things the engine provides, rather than re-inventing the wheel. But yeah, glad it's working at least

#

the material looks fine in the preview

#

but not in the object itself

#

📎 unknown.png

grim ore Sep 21, 2020, 10:22 PM

#

you can use that item as a preview mesh in the material viewport, the bottom right icon in the material viewport and if you scroll down in the details panel you can set it.

#

this would atleast let you play with it to determine why. Off the top of my head what does the mesh look like in terms of Verts and such? also does it have a good UV map and are the normals correctly facing

autumn grail Sep 21, 2020, 10:25 PM

#

yes i have reclaculated normals in blender

#

and reimported

storm venture Sep 21, 2020, 10:26 PM

#

@warped tangle i might look into switching it to the scenecomp version later but the BP the value is inside gets used in a lot of places, and im not sure if i want to add a scenecomp to the BP if its only helping in one place, idk, i just wanna keep it tidier. keep in mind, i agree with you, the scenecomp is definitely the more straightforward approach, lol

Hey all , doing some research into streaming levels vs opening and closing levels. If I were making a game somewhat like Slay the Spire, which do you all think would be better? Streaming levels would be useful since I wouldn't have to reload the player information repeatedly, but streaming levels also seems more geared towards large maps you travel through?

grim ore Sep 21, 2020, 10:49 PM

#

streaming levels can be used for anything that you want to load and unload easily

#

You could be silly and even have just your UI in a streaming level if you wanted for example

#

so a streaming level setup would be fine for your game if you want to say just load in a combat area for a player and unload it when done

another texture bombing question. i've created a texture bomb by hand for one of the material functions that i'm using in my master landscape material, however now get this errors inside my landscape material and the material itself won't render:

Does anyone know under which conditions the Epic Games Launcher is triggered to open alongside the editor? I feel like sometimes it just opens for no reason. If I quit the launcher, the editor seems to be unaffected. Not that the launcher takes up a ton of resources, but it does take up some resources, and if it didn't automatically open alongside the editor from time to time, I'd usually never have it open.

tired lynx Sep 21, 2020, 11:29 PM

#

narrowed the issue down it seems as though the texture bombing area is only affecting the displacement node tree

#

if i unplug displacement i get no errors

#

although i do need displacement so could anybody tell me why this is occuring?

@static sparrow pretty much it tries to show up if the editor is not, so if you do the launcher -> editor it will minimize the launcher then bring itself back up when you close the editor. If the editor was closed it will try and bring up the launcher. There are workaround to get around this by faking a source control with perforce, there is a guide out there but I dont know if it works anymore.

static sparrow Sep 21, 2020, 11:59 PM

It tries to show up if the editor is not what

#

not showing up itself? i.e. not working?

tired lynx Sep 22, 2020, 12:04 AM

#

oh, it seems like the problem is texture bomber outputting in rgb. is there a channel splitter node that i can use to just isolate one channel from the displacement?

grim ore Sep 22, 2020, 12:07 AM

#

if the editor is not there, so if it closed itself when you launched the editor and then close the editor it tries to launch the launcher

I have a blank VP project and I added a single object to world origin. I have added a level sequence and animaed my camera. I don't want the checker floor to render so I turn off that object in the World Outliner. When I render myimage sequence, however, the visibility flag is turned on for the floor.

Why does the render section change my visible objects flag in the world outliner? I don't mind having the floor in my project, but I don't want to render it.

How does the AI Perception's Max Age work? Can the component keep track of actors that were spotted but then left the vision cone for some time? Or do I need to implement my own perception memory somehow?

grim ore Sep 22, 2020, 12:16 AM

#

@vague scaffold the visibility in the world outliner is just for the editor is why, you would go into the details on the item to make it not render or just delete if it you do not want it

#

@ornate forge have you checked out the learn AI course on learn.unrealengine.com ?

ornate forge Sep 22, 2020, 12:16 AM

No, I haven't yet, does it cover that?

grim ore Sep 22, 2020, 12:17 AM

#

I beleive it does, off the top of my head I beleive that is how long it keeps the item as a valid target before forgetting about it yes

#

@tired lynx I beleive you want the Component Mask node

vague scaffold Sep 22, 2020, 12:18 AM

#

It's weird, the sky sphere does not have a render disable flag. It looks like Actor Hidden in Game is the RenderFlag for SkySphere, even though other objects have a separate Render flag.

grim ore Sep 22, 2020, 12:20 AM

#

the sky sphere is a blueprint , you would disable the mesh on it

#

or yes hide the actor since its a blueprint

Hey people good afternoon, one question? If I got a datatable variable with "AllPlayerWeapons" but i need to update one of the rows the has the value of level = 1, can I update the row and this will update the asset?

but there is also component mask or something like that to mask out certain channels
@plush yew component mask is it yeah, thank you. cannot use texture sample in this instance for texture bomber.

does anybody know how to enable the vr editor? i don't have it in my toolbar and the auto-entry isn't working either

grim ore Sep 22, 2020, 12:45 AM

#

@ornate ice how are you updating the data table? they are read only so if you update it directly or reimport a text file then you are fine. If you are trying to update it at runtime, then you cannot.

#

and since it is read only assets only get the data when they need it so it would be valid at that time with the new data

Does anyone know if there is a library of quixel megascans based trees? I've tried creating my own with a TreeIt -> blender -> ue4 flow which works well except TreeIt doesn't seem to have the kind of support needed for quixel style leaf atlases (it looks like manually adjusting the tree atlas textures into something TreeIt likes is a loot of work and I'd probably do a bad job.) I know SpeedTree has a good workflow for it but if I am going to spend money I'd almost rather just buy some premade trees outright if the price comes out similar to a few months of speedtree.

okay well i got the vr editor started but now i have a black square covering my screens with barely visible lines of my scene available at the sides if i turn my head

@ornate ice correct, data tables are default values basically.

gleaming creek Sep 22, 2020, 12:59 AM

#

@azure vault I don't think Megascans do full trees (correct me if I'm wrong)

#

I haven't seen any, and I'd imagine it would be very hard to make a photogrammetry scan of something so big

tired lynx Sep 22, 2020, 1:00 AM

#

full trees is something they've said they are working on

azure vault Sep 22, 2020, 1:00 AM

#

They don't, they offer piecemeal. I generated a tree in TreeIt and then cut the trunk/used a quixel trunk in blender. That all works, but getting the leaves to work correctly with their leave atlas assets is hard

tired lynx Sep 22, 2020, 1:01 AM

#

i'm not sure how they'd do it but probably a combination of photogrammetry and manual assembly

grim ore Sep 22, 2020, 1:12 AM

#

a blueprint is a simple way, parent them all to the scene root (the root of the blueprint, a scene component) and you now have a central pivot to rotate and move them around

#

otherwse combine them and animate them all in your DCC program to do that

#

or uh... You could use sequencer I guess to do it, that would work as well

you might need to clear out the current components before you add new ones

#

it runs every time you change a variable as well, might want it to only run when you tell it instead of on construct

#

If you look at the BP Sky Sphere it has a checkbox called "refresh material" that it uses to run the refresh instead of every construct

right, then increase your lighting

Hi all, not sure where to put this question to be honest. I am trying to help a user with performance issues, they're running a DebugGame build and I want to show CPU profiling information. Typing "stat GPU" in the console shows GPU timings, which is great, but "stat CPULoad" does nothing. Has this command been deprecated, and if so what is the new one? The UE4 documentation I found online doesn't mention this function being removed

Hello everyone!!! I asked yesterday about multi-GPU for Raytracing but i didn't get any replies. Anyway, today i have a new problem, i open a project that i work on and whenever i hover my mouse cursor above a menu or an item, the description box becomes huge and it's like a display issue.

cold vortex Sep 22, 2020, 11:53 AM

#

So, I have a blueprint class that inherits from my C++ class. My C++ class inherits from ACharacter.

If I set "simulate physics" to true on my character's capsule component, I am no longer able to move/control my character.

#

Which is a problem, because I want to ensure this character is capable of swinging around and stuff, Attack on Titan style, but I want the player to be able to control the movement. Anyone know how I can deal with this?

exotic thicket Sep 22, 2020, 12:04 PM

#

@cold vortex you would need to change how your movement logic works. Actors which simulate physics are probably incompatible with the standard character movement component, so you'd need to build something of your own. Alternatively you can fake the physics which may be easier as you'd have more control over how it works

rough knoll Sep 22, 2020, 12:18 PM

how do i check if a static mesh is equal to something (or even has a value)

#

i have slots for scopes in my gun and i want to check if the slot has a static mesh assigned to it

#

if so do something if not do something else

exotic thicket Sep 22, 2020, 12:20 PM

#

It kinda depends on how your slots are implemented

#

If it's just a variable to which you assign something, you can probably use "Is Valid"

rough knoll Sep 22, 2020, 12:21 PM

#

well its a static mesh component

#

inside of the gun blueprint

#

based on whether the scope is equipped or not it either has a static mesh assigned or doesn't

exotic thicket Sep 22, 2020, 12:22 PM

#

Ah, in that case you can probably do Get Mesh and check that using Is Valid

#

if there's no mesh assigned it should be null which should fail the Is Valid check

Hello. I've seen conflicting advice over the years about Macros vs Functions. These days, the only time I use a macro is when I need multiple Exec outputs. I've learned to shun them in every other circumstance. In particular, I've picked up on the sentiment that macro libraries are to be avoided.

Recently I saw some advice that says one should consider a macro if the functionality will never need to be called from an outside class. And a function if it will.

I'd just like to hear what this channel has the say on the subject. Any thoughts?

What does "LIGHINING NEEDS TO BE REBUILT MEAN"? Is there a rebuild lighting button like Apply?

tired lynx Sep 22, 2020, 3:56 PM

#

@vague scaffold yes, it's just the 'build' button at the top of your screen

#

it's for calculating indirect lighting and means that you have static meshes that have been moved or added that have not had their lighting calculated yet

#

best thing is to just build after each large section of your scene is done and go grab a coffee whilst you wait

Thank you @grim ore

that is a content pack, there are googles on information on how to do that. The 2nd one is a level template, same thing.

tried to find info about it, with no luck.

Also there is an official course coming out in the near future that covers both.

You're referring to the learn.unrealengine.com?
If so, what section should I keep my eyes on? You know any release date?

in your engine folder is Templates for... templates, and FeaturePacks for.... content and feature packs

I have been there.
I searched for the string "TimeOfDay" hoping to find an INI file I could learn from. It wasn't that simple.

So if you think the course will be out soon, I could better wait for it instead of collecting small bits here and there

grim ore Sep 22, 2020, 5:11 PM

#

@solid glade I beleive in the first half of october for the course. The time of day is a level template, its found in the "UE_4.25\Engine\Content\Maps\Templates" folder based on your engine version. googling UE4 Level Template returned 2 videos, both by me so I know they exist, that cover new level templates and project templates. With that said Project templates changed slighty 2 versions ago but are very similar.

#

new levels are literally just the map and build data put into your folder

#

new project templates and content and feature packs are basically projects compressed into a .pak format and put in the correct folder for the engine to find

solid glade Sep 22, 2020, 5:14 PM

#

@grim ore

So in those cases where for example TimeOfDay isnt listed, thats becaus ethe .pak file isn't in that particular template folder?

grim ore Sep 22, 2020, 5:15 PM

#

look in the folder I just mentioned "UE_4.25\Engine\Content\Maps\Templates"

#

time of day is a new level template so it's in there

solid glade Sep 22, 2020, 5:15 PM

#

I am in this folder now

#

whats the name of TimeOfDay folder? Am I blind or am I missing something?

solid glade Sep 22, 2020, 5:17 PM

Sorry, my fault. I read your path as another path

#

yes, there it is

#

these .umap files re levels, right?

#

probably pointing to engine-assets, eg the floor etc?

grim ore Sep 22, 2020, 5:18 PM

#

they are levels yep. You can create a new level in a project and build the lighting and navigation. then copy those 2 files into this directory and restart the engine and it should show up. since its now in the engine folder all of the content needs to point to engine content

solid glade Sep 22, 2020, 5:18 PM

#

🤩

#

whats this then?
Dont I need to play around with those too?

📎 unknown.png

#

or will any .umap be found and provided as New level option?

grim ore Sep 22, 2020, 5:19 PM

#

yes that is the 2nd thing you need to do

#

it also copies those .ini entries into the project folder so if you remove a template after making a new project it might be a ghost template

solid glade Sep 22, 2020, 5:21 PM

#

and what would it mean then, the ghost template?

grim ore Sep 22, 2020, 5:21 PM

#

your project would think it has a template to load but it would never load

solid glade Sep 22, 2020, 5:21 PM

#

will it matter that the project was made with a template that I removed?

#

ah
So the templates get loaded every time or?

#

isnt it just the first time when you create a project?

grim ore Sep 22, 2020, 5:22 PM

#

it will not, the template is just copied into your project for you to use.

solid glade Sep 22, 2020, 5:22 PM

#

yes.
got you
And it also copies the ini entries, correct?

grim ore Sep 22, 2020, 5:22 PM

#

in newer versions of the engine yes it copies those .ini entries into your local saved config file

solid glade Sep 22, 2020, 5:23 PM

#

and what did you say would happen if I removed the template after the project (and the ini entiries) was created? Are there any consequences?

#

I am jus trying to think ahead

grim ore Sep 22, 2020, 5:24 PM

#

once the project is created, if you use the template and save that map you are fine. you copied in the template from the engine and saved it locally. If you delete the templates from the engine but leave the .ini entries the new level window will basically show blank entries (nothing will happen when you try and use them)

solid glade Sep 22, 2020, 5:25 PM

#

ah, now I think I understand

of course, they are linked together.
If I erase one, I must erase the second (or, adjust the ini, so that there is no reference to the template)

did I understand you correct?

#

So the project itself holds information of what templates to expect, right?

grim ore Sep 22, 2020, 5:27 PM

#

in newer versions of the engine yes, there are new saved/config files

#

📎 unknown.png

#

before it would just be in the engine but in i think .23 and later there is a saved/config/PLATFORM folder created with .ini files

#

so even if you remove a template from the engine AND remove it from the engine folder .ini files if you created a project with new templates at some point that project knows about those templates still and has to be updated

solid glade Sep 22, 2020, 5:31 PM

#

And if I would send this project to someone who obviously doesnt have my custom setup, it would be confusing ...

#

... if that person would try to create a new level based on my custom template, that doesnt exist in their computer.

grim ore Sep 22, 2020, 5:33 PM

#

yeah their project would think there was a tempate that doesnt exist so it would just show up as blank

#

but nothing stopping you from fixing the .ini file before sending it

solid glade Sep 22, 2020, 5:34 PM

#

yes, I need to know this, so that I can know what to fix before sending 😄

#

**A question
**
Why are there only a few occurrences of "TemplateMapInfos" when there are so many templates?

📎 unknown.png

#

Are they nested or something, reusing "parent settings" or so?

grim ore Sep 22, 2020, 5:38 PM

#

well those templates are for the new project window basicaly, and the .ini files are all default so sometimes it has info they dont use

#

sometimes the use the same folder for the new project template and the feature pack and depending on if its a template or a feature pack it would use some of the .ini files

#

so like the project template might ignore the config.ini and use the template defs but the feature pack would use the config.ini and ignore the template defs. etc.

@sterile tulip yes, all of them when developing

Does anyone know how much RAM the new consoles will have? PS5 and XboxX

grim ore Sep 22, 2020, 5:54 PM

#

and your skill and the BP limits are what would limit your game scope. Bueprints can handle most things but if you needed say 200000000 units in an RTS then you might need some custom C++ to handle that

#

the consoles all have different sizes and speeds and types of ram

#

16gb, 10gb, etc. some of it high speed, some of it lower speed.

scarlet birch Sep 22, 2020, 6:27 PM

Thanks again. After seeing him use it there I'm rethinking using different instances. That combined with some distance blending in the material will probably look pretty good. I tried using dithering but it seemed too heavy.

#

I'm trying to get as much optimization as I can so I can have some room for some other heavier eye candy.

#

Yeah, I see a lot of potential to do some cool things with it. Sjoerd de Jong has probably saved me more time than anyone else. Anytime I see him in something it gets added to the top of the watch list.

Beat Saber has added a new Automatic Player Height setting to help you have the correct block height for each player, without having to go into the Player Settings each time. I go over the new setting and how it works with Floor Height Adjust.

I'm playing the PSVR version of ...

So can you use both vertex color and pivot painting separately on the same mesh? I thought pivot painting used vertex colors but I see now that might be wrong.

warped tangle Sep 22, 2020, 6:41 PM

#

afaik you shouldn't really need to adjust the world to meters scale. Player height is something completely separate @harsh tiger

harsh tiger Sep 22, 2020, 6:44 PM

#

my issue is say for example i can look at a table and everything is fine. but a child puts on the VR headset, they would be underneath the table. how would you recommend i fix this issue so the child would have the same experience as an adult?

supple wyvern Sep 22, 2020, 6:45 PM

#

You cant really do that especially not with multiplayer. Maybe with single player you could get player height and have one bp for the world and call the height from the character and set the scale based on that

warped tangle Sep 22, 2020, 6:45 PM

#

interesting problem. I have found in VR development that changing the persons PoV to something that doesnt match real world can induce sickness etc.

This includes height. So if a child is used to having an eye line below a table, and all of the sudden they are 6 ft tall, that may be disorienting.

harsh tiger Sep 22, 2020, 6:46 PM

#

hmmmm

#

the child becoming 6 foot tall all of a sudden does make sense to be disorienting

#

i think my understanding of World to meters is wrong. i was thinking if a child is playing then lower that number. an if its a tall player then increase it

warped tangle Sep 22, 2020, 6:48 PM

#

no, in fact as you change that number you are going to start seeing some odd results when you walk around a play space

harsh tiger Sep 22, 2020, 6:48 PM

#

glad i asked the question before the implementation then 😂

supple wyvern Sep 22, 2020, 6:48 PM

#

I was thinking instead of adjusting the character you simply adjust the entire scale of the world

#

Get the height of the cam from the floor

harsh tiger Sep 22, 2020, 6:49 PM

#

Get the height of the cam from the floor
@supple wyvern is this a built in function in ue4?

supple wyvern Sep 22, 2020, 6:49 PM

#

Yeah

#

Im pretty sure theres a node that gets the player height

#

Of cam from floor

#

And then you call that in a bp for you world and adjust the scale accordingly

warped tangle Sep 22, 2020, 6:51 PM

#

Having gone down this road, just be prepared. It's not as simple as it seems (to adjust the scale of all objects in the world). This will create issues with intended world bounds, gameplay elements not being where they are supposed to be, etc

supple wyvern Sep 22, 2020, 6:51 PM

#

On event begin play —> call player height from child actor MC pawn or character —> set world scale, and the scale should be the float of the height or something like that, and you appropriately scale it in blender or maya or whatever

#

Thats why you have every world prop that doesnt move in one bp

warped tangle Sep 22, 2020, 6:52 PM

#

I don't know that what you are suggesting is realistic in a dynamic sense

supple wyvern Sep 22, 2020, 6:53 PM

#

It would be tedious to copy that to every bp yes

harsh tiger Sep 22, 2020, 6:53 PM

#

most of the world is dynamic with spawnable actors that can be picked up etc. i get the concept, but even tedious is a bit of a stretch. sounds close to unmanageable 😄

supple wyvern Sep 22, 2020, 6:53 PM

#

Good point

#

Ok i gtg so ill come talk ltr if you still need help

warped tangle Sep 22, 2020, 6:54 PM

#

It's doable, but agreed, unmanageable for a pretty extreme edge case (a child playing your VR game)

harsh tiger Sep 22, 2020, 6:55 PM

#

i'll see what other methods i can find and push comes to shove i can revisit this method at a later date. thank you both for the help!

@rich furnace in that instance in the top you can see in the debug filter you have nothing selected, so you will not see the debug in that graph since you have nothing to debug. You should choose the instance you want to debug from that drop down

also are you running the project or just hitting simulate?

rich furnace Sep 22, 2020, 7:39 PM

@grim ore I've set it to the preview window...now I can't change it after

grim ore Sep 22, 2020, 7:40 PM

you should be able to change it on the fly, if you dont see it in the list then that blueprint is not active

rich furnace Sep 22, 2020, 7:40 PM

#

it shows simulating when the game is running

#

ohhhh

grim ore Sep 22, 2020, 7:44 PM

#

I dont know what to say, what does it show for your current debugging object when its running? I cant see it

#

also your first screenshot was a parent and the 2nd a child so ...

rich furnace Sep 22, 2020, 7:48 PM

omg now its working

#

somehow I got the dropdown back and selected teh anim blueprint

#

thanks Mathew! love your youtube vids btw

grim ore Sep 22, 2020, 7:49 PM

#

well the drop down is hiding in that little arrow in the top right next to skeleton

#

your screen isnt wide enough to show it is why

rich furnace Sep 22, 2020, 7:49 PM

#

omg you are right its under the >>

faint roost Sep 22, 2020, 7:49 PM

#

Does anyone have an idea of why a point light doesn't save the intensity level I'm specifying every time I change it, save, and reload the level? It goes right back to what it was before even after saving the level

#

(also a big fan of your videos Mathew! I swear you're the only person I've seen on YT who explains things in a way that helps me actually get my head around it. Thanks for those, seriously 😄 )

rich furnace Sep 22, 2020, 7:50 PM

#

god finally now I can see whats going on .... I have been printing out values to the screen and taking screenshot lmao to see what the values are before it disappears

grim ore Sep 22, 2020, 7:53 PM

#

@faint roost is it setting to default or a different number? perhaps you are going over the limits. Id you change it a small amount, like add 0.05 or 0.5, does it do the same thing?

faint roost Sep 22, 2020, 7:53 PM

#

It was at six originally, I change it to 0.05, save, reload the level and it's back to six 🤔

#

Other changes in the level (adding random cubes, etc) seem to persist on reloading it

#

There's nothing in the level blueprint that would be setting the value

rich furnace Sep 22, 2020, 7:55 PM

#

Just want to confirm...if I modify the bones in the animation, I need to record a new animation right? There is no way to save the modifications directly?

#

also I notice a discrepancy between the socket location. for my example the ball shows attached to the hand but when I run it shows up clipping in front of the camera.

faint roost Sep 22, 2020, 7:58 PM

#

@grim ore no change when incrementing smaller amounts, either

grim ore Sep 22, 2020, 7:58 PM

#

@faint roost is it just that one light or all?

#

@rich furnace you can edit the animation directly yes, you move it to the play you want. hit add key to add a curve modifier to that spot in the animation and for the changed bones, then apply and it will save the new modifier track.

#

might be smarter to copy the animation first and edit the copy

faint roost Sep 22, 2020, 8:00 PM

#

Other lights seem to save correctly. I guess I'll need to remake this one. Unfortunately it's the "sun" of the level, so I was hoping to avoid that, but it looks like something definitely bugged out with it, so that's what I'll do. Thank you for the help!

grim ore Sep 22, 2020, 8:01 PM

#

is it linked to anything at all if its the sun of the level?

faint roost Sep 22, 2020, 8:02 PM

#

Not that I can tell. There's nothing in the level blueprint, and it's not parented to anything in the level hierarchy.

rich furnace Sep 22, 2020, 8:02 PM

#

any idea why the ball is in a different location between animation preview and the gameplay?

grim ore Sep 22, 2020, 8:03 PM

#

@faint roost super duper weird 😦

faint roost Sep 22, 2020, 8:03 PM

#

It's okay, I can just go ahead and re-create it, was just wondering if anyone else had seen this kinda strangeness before =)

grim ore Sep 22, 2020, 8:04 PM

#

If it was part of say the sky sphere or the new time of day BP I could see it being weird but those are directional lights normally

#

@rich furnace nope going to have to debug or see whats going on. I assume in the preview its attached to the socket and you are doing the same in the game? perhaps its a collision issue in the game and its being pushed away

rich furnace Sep 22, 2020, 8:05 PM

#

appreciate the help Matthew!

narrow mauve Sep 22, 2020, 8:10 PM

#

Is there no way to change the channel of the skylight or have certain meshes unaffected by it? It's ruining lighting on some meshes for me but I need it for my open world

"doesnt work" is a broad description

So, all my guns inherit from the gun parent. I made a new gun and a new projectile type for it.

grim ore Sep 22, 2020, 8:32 PM

did you try to rebuild from the source? did you look at the logs to tell you why it did not build?

#

there is no guide for updating, you fix the issues and you compile it

golden condor Sep 22, 2020, 8:33 PM

Thing is, from the gun parent I set it up so it only used one projectile type

grim ore Sep 22, 2020, 8:34 PM

Yea i saw a youtube video once. guy was using 3d character but it made it 2d pixelated at runtime

grim ore Sep 22, 2020, 8:48 PM

#

@crimson vapor if this is a source plugin you need to install visual studio and compile the plugin. The issue is you need to read the log for the project to find out why its not compiling

#

you cant get around this part

#

@golden condor so the variable in the children only show the one projectile? did you make more and are they children of that one projectile or different? if different you probably are using the first projectiles class so of course it wont accept other ones. You can use something more generic like Actor if you want

@grim ore i dont want the player to use things though walls be facing the wrong way and activating them.

grim ore Sep 22, 2020, 9:45 PM

#

@stiff sail then add conditions to the volume, such as if they are looking at the item (using the rotation and an dot product) or using a line trace to see if the player is looking at it with nothing in the way, etc.

#

otherwise add a collider to the front of the player that you use to determine if something is in front of it instead of a collider in the world. or uh put the collider in the world in the right spot so they have to be near it and not on the other side of a wall. etc..

yep find a lawyer who specializes in that subject and pay them to find out for you, thats about the only way you will get a real legal answer

other people might even have experience but that doesn't mean it will be the same with your ip

sorry for being off topic everyone

If the company goes bankrupt, who gets the IP?

frigid needle Sep 22, 2020, 9:55 PM

#

Depends on each individual situation

exotic plover Sep 22, 2020, 9:55 PM

#

Individuals who once worked there?

#

or does it fall into some kind of lost space, where the ip is unclaimed?

frigid needle Sep 22, 2020, 9:55 PM

#

That is something you'll want to check with a lawyer about, as they'll be able to go through the legaleeze that speaks to that sort of thing

It, again, depends on each individual situation

#

and how their IP rights were setup, what agreements they entered, etc

Everything has a location in the layout. There's something like an overlay? can't recall the name that lets things stack.

quick question

does rtxgi completely remove the need for light building?

rtxgi is run time I beleive so it doesnt replace the build if you are trying to use built lighting

there is a gpu lightmass replacement coming soon that does use the GPU and is much faster than CPU so it would help with that

Is it feasible to make a naval warfare sim like world of warships on unreal engine? I know games like WoWs and Warthunder have their own dedicated game engine and I’m wondering if that idea is even possible.

tired lynx Sep 22, 2020, 10:17 PM

#

there is a gpu lightmass replacement coming soon that does use the GPU and is much faster than CPU so it would help with that
@grim ore ah that'll do it. looking forward to that

#

does unreal engine have a notes feature built in?

#

just like

#

a place to jot down key figures and stuff inside a project

#

this project's starting to get a little 'math'y and i need a way to keep track

@gaunt pivot It should be feasible, yeah. Make a list of what it is you need in order to replicate the idea, and then start doing research on how to do that in Unreal

Creating a boat in Unreal

I am running into issues
All my weapons inherit from the same weapon parent
Problem is, I made a new weapon that I want to act like an RPG from Team Fortress 2 so when the player is in blast radius the player is launched up.
I thought changing the projectile and adding the code there would work but I can't change the projectile on my weapon
Because my weapons again, all inherit from the same parent.
And the parent takes one type of projectile.

hey so, is there no way to blend between materials procedurally using the noise node?

#

i've been scouring the internet for an example of it being done this way, but every example i've seen simply uses a static noise texture.

Yo, I was wondering if anyone had a DCS and a Rpg inventory integrated already. I know how to do it myself, But Im at my third try now. (Each time was a fatal bug. )

What would cause a map to fail, especially if there is no version editing found in perforce
my main demo map keeps crashing upon load (took a while to figure out that was the problem) but I can't for the life of me think of anything that changed it
I simply "opened it yesterday" and saved project settings for it to be the demo map
i didn't even touch the level

What node would I use to combine a RGB from a Texture Sampler with the RAW Comparison value from a ChromaKey? I need to integrate the alpha.

light thunder Sep 23, 2020, 12:20 AM

I'm dead in the water until I can figure out why this map is crashing unreal:
1 - no revision history in perforce
2 - no autosaves I can find (opened the map yesterday and was looking through some blueprints)

Maybe look at why its crashing instead?

You could run a Resave Packages commandlet that will tell you if your Map is corrupt.

#

Have you tried reverting to previous revision?

light thunder Sep 23, 2020, 12:23 AM

#

last time the map was editor according to windows was months ago

#

I'm trying to think of the things I did in blueprint, if that messed it up, it should crash and give me a crash report

weary basalt Sep 23, 2020, 12:23 AM

#

It may not be an issue with the Map, but potentially an issue with an Asset that is being used inside the Map.

#

Did you change any assets that the Map uses recently?

light thunder Sep 23, 2020, 12:24 AM

#

Yes but why would it crash upon load, I could see upon starting the actual game

#

but there's very little pre-run execution going on

#

you didn't see anything in that log did you?

#

nothing that's a red flag to me

#

I could revert all my changes from perforce, I'd lose a few hours but my fear is somehow something else got changed and I'll lose the work and not fix it

#

I'm opening up the blueprints I was working yesterday but if they compile fine, what areas should I look for that would crash something before runtime?

#

AH

#

i remember now, thanks for walking me through it

#

I'm not sure why it actually is being a problem, I can't find any changes

#

Is there a way to open a map without any references to certain blueprint somehow? like a safe mode? @weary basalt

weary basalt Sep 23, 2020, 12:42 AM

#

Running a Resave Packages commandlet will compile/save all of your assets to ensure they are valid.

light thunder Sep 23, 2020, 12:42 AM

Unless I'm using perforce wrong (I'm using "Get Revision" when the editor is closed and going back like two revisions)

Scrollboxes, great for lists of items but not great for when you want to use Item Icons in rows and collumns. So, in this instance use GridPanel. However is there some easy method to get them to add child in order from left to right, top to bottom? I feel like the manual process I am setting up is just wrong.

Does anyone know why visual studio 2019 would be constantly stuck at 100% disk use when automatically opening a UE project but not at any other time? Normally when I use it it's ok but when I created a new project and VS opened automatically from that it loaded the project but was pretty much constantly stuck at 100% disk for seemingly no reason until I killed it after a few minutes (since my laptop was pretty cheap since I didnt have much money at the time and is already 2 years old and has a mechanical hard drive so I didnt want to waste any more of the drives longevity than I really need to), despite not having much ram to work with the memory wasn't full at least not according to task manager (it was at 83% though :/) so I dont think it was trying to use swap/page file? If it was I imagine the editor would be effected too but it wasn't using much if any % of the disk at all, only VS was

light thunder Sep 23, 2020, 1:54 AM

@manic pawn it's blueprint project

oof

tight birch Sep 23, 2020, 1:55 AM

So I'm thinking to avoid this issue in the future maybe I could use VScode instead of visual studio

But idk how to do that

grim ore Sep 23, 2020, 1:55 AM

@tight birch this is a C++ project and your talking about with the solution open? it could be intellisense building its database

tight birch Sep 23, 2020, 1:56 AM

#

@grim ore Ye it was a c++ project, I'm pretty new to UE dev, is that normal for a UE4 C++ project

grim ore Sep 23, 2020, 1:56 AM

#

@marsh swallow welp you pretty much have to specify the row and column which is basically a grid or an array you can loop thru. what is your manual process you are doing?

#

look on the bottom left of VS and see if it shows a moving icon and intellisense building

since its only 2 columns, i am just flip flopping and then adding 1 to the row on the flop, so the next flip is the next line down.

#

i mean with 2 rows not so bad but you would think this is kinda basic use enough to have a function/something built in that automatically does this. lol

grim ore Sep 23, 2020, 1:59 AM

#

@marsh swallow sounds like a simple loop, nothing wrong with that

it was just one of those "feelings" of doing something wrong. lol

grim ore Sep 23, 2020, 1:59 AM

#

well you would make the function basically since it has no idea of knowing what you want to do with it, its just a container you set up

marsh swallow Sep 23, 2020, 2:00 AM

#

sure but many games commonly use the whole collumn/row thing these days. i guess im just being picky. 😄

#

thanks Mathew! I shall continue on

grim ore Sep 23, 2020, 2:00 AM

but no it sounds like you are doing fine and a flip flop seems like a novel way of doing a simple 2 item loop

light thunder Sep 23, 2020, 2:01 AM

this IS the correct way to roll back changes right?

📎 unknown.png

#

everything was working then but she dead now

grim ore Sep 23, 2020, 2:01 AM

I assume the scrollbox didnt work out well since you wanted more than 1 item in the row?

marsh swallow Sep 23, 2020, 2:01 AM

#

yeah pretty much

grim ore Sep 23, 2020, 2:02 AM

#

yeah doing it your way might work well, or a uniform grid panel, assuming you dont want the items linked when you scroll

#

putting the entire grid panel in a scroll box should work and do what you want in the end if needed

marsh swallow Sep 23, 2020, 2:03 AM

#

also... wait you have Perforce AND dropbox? You know you can use perforce to sync those multiple computers the same way and more efficiently. Also you would revert the submission however, you might just wanna pull the single map file. More likely than not however, chances are you deleted a dependency file somewhere that map used. We have had it happen from time to time. but we catch them pretty quickly so we only ever loose 1 revision

light thunder Sep 23, 2020, 2:04 AM

#

The dropbox is before I moved to perforce, but I guess I can stop using it for that

manic pawn Sep 23, 2020, 2:04 AM

#

no, the correct way to roll back is to right click the changelist above and select "undo changes"

light thunder Sep 23, 2020, 2:04 AM

#

the map file has NO changes

#

hasn't changed since like, february according to last revision

manic pawn Sep 23, 2020, 2:05 AM

#

at least if you want to actually submit that rollback

I want to make it work lol

I thought get revisions would do that

marsh swallow Sep 23, 2020, 2:05 AM

sure the map hasnt, but did you delete something that map depended on and force fix redirectors?

light thunder Sep 23, 2020, 2:06 AM

it will undo, then you submit it

that cascades or is recursive right? if I undo change 5 (and am currently on 10) will that undo all of 5,6,7,8,9,10, or do I need to manually do it?

im having trouble with getting my progress bar to react to some AI damage the Number string beside it reacts just fine for health but the progress bar health does not react

this layout is what i have for stamina as well stamina is working health is not for whatever reason only the number string is

📎 unknown.png

#

i feel like its a bug since when i take damage a diffrent way without the AI it reacts

grim ore Sep 23, 2020, 4:57 AM

what is the value for health? what is the number

cedar jetty Sep 23, 2020, 5:00 AM

#

@grim ore 100.0

grim ore Sep 23, 2020, 5:01 AM

#

the value in a progress bar is between 0 and 1, so if you are telling it to use 100 it will not work

cedar jetty Sep 23, 2020, 5:01 AM

#

gotcha

#

@grim ore worked only thing is is i want it to be 100 health because i wanna take varients of damage not just from 0.1 to 1.0

grim ore Sep 23, 2020, 5:07 AM

#

then keep it at 100 health, you just need a value from 0 to 1 (0% to 100%) to put into the progress bar. Your current health divided by your max health gives you this value.

cedar jetty Sep 23, 2020, 5:11 AM

@grim ore thank you man now i just have one more thing im stuck on

#

im trying to replicate bullet damage to the AI and i know there are multiple ways of doing it whats the recommended way?

grim ore Sep 23, 2020, 5:13 AM

replicate is a specific thing dealing with multiplayer, do you mean that or something else?

cedar jetty Sep 23, 2020, 5:15 AM

#

not replicate but like trying to make damage happen eventually though ill want to make it multiplayer based

grim ore Sep 23, 2020, 5:15 AM

#

if you actually plan on making it networked you have to design it from the start. for now what are you trying to do?

cedar jetty Sep 23, 2020, 5:16 AM

#

what do u mean design it from the start how far to the start are we talking?

silk lintel Sep 23, 2020, 5:16 AM

#

So I'm trying to create a paper-like material and I'm not quite sure how to deal with lighting. I want to be able to see the soft glow of a light through the paper, but I don't want emissive because that would be a constant light regardless of lighting on the other side, and I don't want translucency because I don't want the other side to be visible necessarily, just the light. Definitely not masked. 1) is there any way to do this, and 2) is there any way to do this and also be able to use pbr controls (metallic, roughness, specular)?

grim ore Sep 23, 2020, 5:16 AM

#

are you just trying to damage something you hit? that depends on what you are hitting them with and how. it also depends on what you plan on hitting eventually and how and etc.

#

designing a single player game and systems then changing it to multiplayer is a nightmare. if you plan on doing multiplayer you do it from the start, you start the project and everything is done with multiplayer in mind.

#

dealing damage in single player and dealing damage in multiplayer are completely different especially once you consider if its a listen or dedicated server. then you add in stuff like UI and animation updating just from that one piece of damage.

#

@silk lintel you can look at something like the 2 sided foliage shading setup, its similar to that

cedar jetty Sep 23, 2020, 5:18 AM

#

this system that i got i believe already has that in mind considering i got this system from the marketplace it even has a tutorial on how to run a deticated server on it

grim ore Sep 23, 2020, 5:19 AM

then if you are using a system already how is it set up to deal damage

@grim ore thats the function lemme find what calls it

well that looks like a damage calculation function

what causes these shadow issues

could be how far away you are for the shadow maps, that looks like dynamic lighting?

@grim ore

📎 unknown.png

grim ore Sep 23, 2020, 5:24 AM

#

yep you just call the apply damage event to the character this is on and it should handle it. so how you apply the apply damage depends on how your weapon is designed. physical object, line trace, etc.

#

but you should basically just call the apply damage node with your value on the target and this would receive it and handle it

cedar jetty Sep 23, 2020, 5:32 AM

#

@grim ore how can i have it tell if its being hit with my projectile?

grim ore Sep 23, 2020, 5:33 AM

#

your projectile should have a collision event on it and when it hits something it can apply damage to it

cedar jetty Sep 23, 2020, 5:33 AM

#

ok

grim ore Sep 23, 2020, 5:34 AM

#

you could do it the other way as well and if something collides with the ai it checks for what it is and then applies damage but thats odd, doing it the projectile way it would know if it should damage something and how much and would be easier

cedar jetty Sep 23, 2020, 5:35 AM

#

like add on to this i assume

📎 unknown.png

grim ore Sep 23, 2020, 5:41 AM

because i put a print string onto the projectile when it hits something

#

and no print string

grim ore Sep 23, 2020, 5:43 AM

#

well for that your running single player, I have no idea if it will even call server code in single

cedar jetty Sep 23, 2020, 5:44 AM

oh so i have to setup server first?

grim ore Sep 23, 2020, 5:44 AM

put the print string on the event any damage before the server call

im assuming i did this wrong?

📎 unknown.png

grim ore Sep 23, 2020, 5:45 AM

#

yes, you should be calling apply damage on the actor you hit

#

apply damage will call the "event any damage" on the character and then it would do its custom code

#

you might want to see if there is an example with this pack or docs, I would think it would be covered in there

cedar jetty Sep 23, 2020, 5:47 AM

#

should i be using any of these events?

also ill check rn

grim ore Sep 23, 2020, 5:47 AM

your calling Svr Damage on the ai

call Apply Damage instead

@cedar jetty then you need to start debugging to find out if its hitting the ai, and if the event is being called.

@silk lintel i dont think it works like that, I beleive it "fakes" it in the material

did you try changing your subsurface color to something other than white?

I am creating a fully 2d multiplayer card game in ue4. Quite a few people have told me that by using ue4 I cut out a large portion of systems that can run game from the get go. Considering game is going to be very labor unintensive is their anyway that I can cut out some of the editors more demanding capabilities on release (does that even help) or would I need to port to a lighter engine like game maker studio

does unreal engine have an abstraction layer for arbitrary tcp socket connections or do i have to write target specific networking code for each target I want to support in unreal engine?

Hi all, I have a weird problem that I can't explain. I have a function for cycling through your inventory which is bound in the editor to Mouse Wheel Up and Down, but it doesn't work at all. Scrolling the mouse wheel does nothing. Here is how the input is handled in the editor and code:

#

https://gyazo.com/8d1c4f3a3180ac6d1c0dd5a563fe4648

Gyazo

#

The log never happens

#

Every other key binding works fine, and switch item up works fine if I rebind it to a different key in the editor

#

My mouse wheel isn't broken, it works fine

#

Any ideas on what's happened? It used to work fine, and sometime over the last month or so it just stopped and I don't know why

Hi everyone - does anyone have an example of uploading a file via blueprints to an external server? I"m using node as my API and I can deploy formidable or mutler for file uploads, and I can execute JSON requests fine throughout my UE4 project, but the issue is that these "file handler" modules for node require multipart forms, and I'm not sure how I would do that with VaRest or any existing Blueprint tools. Does anyone have any example of file upload to external server via Blueprints? If I could see one example of a file upload in any way from UE4 I could figure out the rest.

Thank you much in advance for any help.

analog prism Sep 23, 2020, 10:38 AM

#

Just a follow up to my question above, I've determined that the problem is caused by assigning 3 bindings to mouse wheel up. I also have two other functions, one for zooming in when using a spyglass, and another to zoom the camera in when using an orbiting camera. For some reason, removing the binding to the spyglass zoom in fixed switching items and zooming the orbiting camera in

#

I looked at the spyglass zoom in function, I don't see anything special about it, is there some kind of limit to how many functions can be bound to a key in UE4?

#

Actually no, it's not the number of bindings. It's just binding that one function to zoom in the spyglass. WTF? Why would binding one function in particular to a key then stop all other functions bound to that key from registering?

@analog prism maybe your other binding is consuming the input event? you could try using an unbound key to check if this is the problem. I don't know how to disable consuming events in c++ but there has to be a way

Is there ANYWAY to open up a map in a safe-mode?

analog prism Sep 23, 2020, 1:30 PM

#

@last willow You might find it quite challenging jumping straight into a game engine, as UE4's implementation of C++ has a lot of abstraction layers built on top of it which obscure a lot of the underlying complexity. If you're an absolute novice to programming, I would recommend looking up some beginners courses and creating some small applications so you get a grip of the basics before you start looking at UE4

#

But if you want, you can look at some introductory videos and get started with blueprints

#

Or, and I realise this is an Unreal Engine Discord, but Unity is quite user friendly and intuitive for beginners. The idea of writing scripts and attaching them to objects to make them do stuff is a bit easier to understand than creating a new Character class and overriding functions in C++

HLSL are the shaders, the code that tells the graphics card what to do. Materials tell the shaders what to do. Sort of.

Hey, I want to create a terrain based on a noise function. Now I need to extract height and color information from the generated noise. Is it somehow possible to access the applied noise texture on a static mesh (plane). I thought about retrieving sample points from the texture to extract the needed information. Ideally something which streams those texture pieces from gpu to cpu or so.

just the map (though it obviously crashes when you have the map set as default, I had to change the ini file to even get it to load)

#

I could have sworn it loaded fine the other day but it is also possible it didn't survive the 4.23 to 4.24 update

#

it's a large map with about 24 sublevels, I'm opening up all of those and finding none of the shaders were compiled for them

normally that wouldn't matter I'd just have to compile like 10k shaders but it would crash

thats what I am curious about, can you migrate out the map from in the editor? if not can you just move just the map to a new project and see what happens

migrating out the map might be an issue, I assume it would try and load it then crash again on the same part (but this might give another chance to catch it in VS) but if not if you just move the .umap over to a new project and try and open it I wonder if will open in a broken state

What do you mean?
@thick herald i mean that when i add an asset into the scene it always imports as static and throws the 'lighting needs to rebuilt message'. i have to manually set each asset to moveable

@grim ore It took a few different tries, normally I was getting overrun errors from some UnrealNames.cpp file, but in this case, It was the StasticMesh.cpp file (most recently) and it even fires on some of the sublevels -

        int32 UniqueIndex = 1;
        while (UniqueMaterialSlotName.Contains(FName(*UniqueName)))```

Is there a Blueprint node (for materials) that can invert values from zero to non-zero? e.g. I want to use a mask that is active whenever my value is non-zero so I'd use an invert function for that (if it even exists)
