Edit: apparently this subreddit doesn't like URL links as can only really post 2 links. So I had to rewrite the post a bit

So I made bullet tracers from a long cylinder with a glowing material. The design is simple as just attach the tracer shooting component on the muzzle of the gun and shoot forward. I made a Niagara effects and an actor projectile version. I have some questions and need help with answers for both but if you can only answer one then that is fine too.

Questions about Niarage vs moving actor methods:

1. Is the Niagara effects tracer method more efficient as running on the GPU than using a normal moving actor tracer which I assume is running on the CPU? I say less efficient as if multiple bullets flying on screen, the moving actor tracer version may face bottleneck right?
2. For the Niagara effects tracer, I know they don't really interact with the world as it is mainly superficial, thus why I have a line trace for damage. But I need the Niagara tracer to disappear when hit something so I add and use a 'collision' module in the Niagara system graph node but it says it's using a CPU ray trace? Does it make this method overall still more efficient than the actor tracer method or no difference?
3. For the moving actor tracer, is it better or more efficient to use a blueprint to make it move or the ProjectileMovement component?

Questions about tracer flickering at high speeds

• Here is a google drive vid link of normal tracers when their speed is small with the value set to 5,000 (each unit is apparently 1 cm to 5000cm/s is 50m/s). As you can see the tracer look normal as the tip of the tracer up close NEVER goes past the center of the screen and just shrinks.

• Here is a vid link of normal tracers when their speed is small with the value set to 50,000 or 500m/s. And the tracers has this ghosting flickering effect as you can see the tip of this tracer DOES goes past the center of the screen and then everything shrinks in the distance.
  • imgur link (interesting only imgur upload can see it and not google drive upload. also sorry it's a bit blurry from the imgur compression but at least you can see the flickering effect)
    • https://imgur.com/a/kitUBK8
  • google drive link cna't show, (but in it you can't actually see the effect which is weird, I wonder if google drive compress the 60 fps vid and thus can't see the effect. Like I can see how compressing removes it but doesn't solve the main issue why it appears in the first place
• My question is why this happen and how to fix it, or is this an innate issue with unreal and the only solution to make it slower?

I'm fairly new to UE5 and I wanted to make a multiplayer game. Currently, it's configured to use the EOS Integration Kit plugin, but I have previously had it set up with the normal EOS Subsystem as well. In either case, whenever my CreateSession is called, I get 'CreateSession - Cannot map local player to unique net ID'. I've tried searching online for hours but it seems like an issue that not many people encounter. My create session blueprint is really simple and should work (attached) and below is also my EOS Integration Kit config from defaultengine. Am I missing a step here? I'm not sure what to do.

I have a widget that supports both mouse and keyboard. However whenever I click on the screen the focus on the button is lost and I cannot use the keyboard to navigate anymore.

Any idea how to fix this issue?

I noticed when trying to find freelancers to hire for my project is a bit difficult. A lot of the systems, if not all of them i can make on my own but am forced to divide my work between others since i work during the day and get home super late into the night.

But since ive been getting more tired recently, i wanted to essentially hand off an inventory system to a freelancer. A, I kid you not, Inventory system akin to Pokemon Red on the Gameboy. (Its charming)

A lot of the rates for just this is around 3000-6000$. Am i crazy or is this normal. Ive never had to hire a freelancer before and anyone can price their work at whatever they want but thats a lot for someone like me 😭

Is this actually normal for freelancers?

Tldr; Pokemon Red Inventory system costing almost 6000$. Is this real chat?

Edit: I know how to make the functions myself, its just that i dont have a lot of time if that confused anyone. Its also bare bones inventory exactly like Pokemon Red, not any newer iterations of this system in newer titles, that would make it more complicated. I also have all of the visual assets like ui and such. Only code is needed really.

What is the most up-to-date way to make such a material? I have seen a lot of 'hacks' and stuff that didn't really work for me and even bought a plugin that didn't work. Any help would be greatly apperciated.

Hi everyone,

How do you work as a team to code while tracking progress in real time?

I come from Roblox Studio, and I find their team collaboration system excellent—you can see live updates of what’s being done. Is there a similar feature on Unreal Engine?

Thanks for your answers!

The default UI is 1px by 1px on my machine. If I increase the scale using either the shortcut ctrl+shift+w, or in the editor settings... I now can't do things like creating c++ classes, or deriving blueprints from c++ classes. Or any of the popups like this. Can someone please help me figure out a solution so I do not have to guess about what my mouse is clicking on anymore? I can read and do anything else if I increase the UI size. However, doing anything like I mentioned is impossible, and it will not let me resize the box. So what can I do? I'd like to be able to set a default UI size that is readable and leave it there.

I am a software developer who is new to game development and Unreal Engine. I created a 5.4 project where i dabbled around a bit in creating a basic open world. Next, I wanted to add a Paragon character (in my case Sevarog, but I think the problem exists for all of them). I added the skeletal mesh to my scene without issues, but when trying to open the provided Level with the animations setup, but could a compile error when trying to run it stating:

Could not find a function named "ResetOrientationAndPosition" in "SevarogPlayerCharacter"

In the Event Graph it shows that there is a Blueprint node for a function call for it, but it states the function doesn't exist. For some reason I'm not allowed to add screenshots to my post, so I hope you know what I mean. My assumption is that this function used to exist in prior versions of UE, and the character's event graph's haven't been updated in the marketplace. I assume since i'm not doing any VR stuff, I can maybe ignore and remove this, but I would rather understand how to fix it.

Is there a function which replaced "ResetOrientationAndPosition" that I can call instead? If so, how do I connect it to fix the graph? Or are the Paragon character's animations and event graph's just broken in newer UE5 versions?

*Update...Fab deleted the asset in question 1h after the complaint. Top !

*Update2...Actually he deleted it

I am looking to buy a new laptop, and need to know what will be the requirements for unreal engine to make 2d games. I will be primarily working with paper2d and paperzd, trying to make indi games. The furthest I will go is maybe 2.5D styles, maybe something that has post processing like lightings and stuff rather than purely 2D. I wont be using stuff like ray tracing or anything most high end games use.

Please let me know whats the minimum CPU and GPU requirements that will be the best for this use case. I also would be glad to know if there is anything I have missed and should consider in this decision.

Note: I need laptop specs, not pc. Thank you.

In my sales listing there is a row that looks like this:

Does it mean that I sell anything or not? Or maybe it means that someone bought it and refunded?
I did not give it for free.

Hey folks,
I'm playing around with the MediaRenderQueue and want to use unreal.MoviePipelineLibrary.load_manifest_file_from_string in Python to load in a manifest from a shared network location.

Is this actually doable? I always get errors that the path can't be resolved by SearchForPackageOnDisk. Do those paths have to always be relative to the game folder?

Hey, need some fresh info and opinions about using this graphic card with current ue5. Most articles i found are talking about 5.1 and mamy problemem that were exisiting right then. Would like to know if the problems are still there or maybe with new ue versions its a lot better?

There are only a few console commands that work in this game. One of them is t.maxfps 100. This command actually works. Other commands either say command not recognized when they are literally showing up in the autocomplete/suggestions. Other commands are literally giving no output.

This issue is at least a few months old for me. Is there something I might have done to make these commands disabled? I think my INI files are not being loaded anymore, either.

Can someone please show/tell me(ideally though video or pictures) a clear way on how to make a basic mouse sensitivity slider on a widget. I have the widget setup and a menu system already have the slider ready to go just need the logic.

For the love of god please don't show me through event begin play, I need to know how to do this specifically in a separate menu/ui widget. Nothing on youtube works for this. I will throw you $30 for the trouble via paypal. Going to bed now probably won't see this till around 1pm est.

We made a turret and put all the code to make it shoot when the character is in the area, however on our own we're supposed to make the turret actually rotate it's head towards the player when the player is in range, and then shoot when the firing line we made for the turret's barrel overlaps the character.

I can't figure out how to make the turret rotate towards the player. Because we're supposed to have an understanding of the fundamentals of it, which I am evidently lacking, we're explicitly told not to use Pawn Sensing, Rinterp, FindLookAtRotation, automatic 0% if we do.

All I know is it involves using the dot product...... and I have no idea other than that.

I've been using Unreal Engine for 3D purposes for years, but I've barely touched Paper2D and I've never used it for any projects officially and everybody seems to say such negative things about it and downplay its potential.

Can anyone please fill me in on why everyone seems to think Paper2D is at the bottom of the food chain for making 2D projects? Is it missing crucial features or functionality in any way?

Hello all! Septimus here, I am showing off more of my game today!

To recap, I'm making a game about being trapped in a cave and wanting to get out. Charred is a 2.5D Metroidvania game, originally being made in Unity, but now being down in the Unreal Engine 5. Here is a link to the current Dev-Log I posted on my YouTube channel:

https://youtu.be/DyYgPs0fzdY

I'm not an experienced programmer, focusing more on art, but I have begun learning online on how to work blueprints, and so, I've completed several features of the game, including:

- The beginning of an interaction system, where the player can hover over an asset and interact with it, resulting in different effects and events.

- The player can now transition between rooms easily. This a big thing for Metroidvanias (and games in general...), and will aid me in level design moving forward.

- The Universal and Modular health system is now FINALLY working. After some reworking, it is now working fine, and can be attached to an object and actor.

And that's all for now! The art side of things has been slow, but I hope I can start letting my programmer friends aid me more with this project, and I can begin making more art for the game. If you're interested in the project, and want to help support it, check out our Discord Server! Thank you and happy holidays!!

Have you tried it out, or is it just me?

I have tried with some different glasses, all visible in Lumen and in 5.3 Path tracing, but totally invisible in 5.5 PT.

Do you know any workaround?

Thank you so much!
