[grand ravine]

a lot of blender models I see are just imported to very small scale, like ant level scale

not sure why, im not a blender expert

[azure shore]

yeah could just be that too but based on the grid size I don’t think it should be that small

helps to import the mannequin itself into blender to check

[cedar peak]

It's because they don't set the scale right. In Blender, in order to export to Unreal, you need to go into Scene Settings, change the measurement to Metric, and then set the scale to 0.01 so that the models are measured in centimeters. From there, set the dimensions to what you think is appropriate for the model, then it'll work. I got over this problem pretty quickly because when the models import really small, you lose rigging weights and the transforms don't work correctly. So for rigged meshes in particular, you want to set the scale correctly. But if nobody told you you had to, it likely wouldn't occur to you that you'd need to.

That said, I didn't think that was the issue because the model itself showed up fine but maybe it is a scaling thing.

[grand ravine]

it definitely has been antman'd

I had to rewatch a few times, i thought it was a spec of dirt on my monitor

[grand ravine]

This is helpful, thanks, I'll do this

before I would just import a model I knew was "normal" scaled into blender from unreal

[hidden dew]

I've learnt that UE4 has a feature where it throttles its own performance if it detects that it's on a device running on battery.
There's a Slate command to tell it to stop throttling, but for whatever reason my UE4 now starts up and thinks my plugged-in laptop is on battery every time, so it won't run to full performance until I hit that command. Every time.

Anyone know how to make it stop doing this?

[tall escarp]

It's important to establish your base unit in unreal before adjusting blender to match (are you measuring in cm, meters etc)

[cedar peak]

While that is true, Unreal Engine by default works in Centimeters which is why this particular trick works for Blender users.

[tall escarp]

I used blender to create my modular architecture lol I know how both work.

[cedar peak]

I know. My comment was in reply to what you said but was more so for the people using blender who didn't already know it.

[past drum]

please for any project let talk

[spice ruin]

Is that meant to be you looking for a job?

[quasi jackal]

How could i possibly create a drop shadow for subtitles?

Like for example..

[azure shore]

the shadow option in the text options

[tall escarp]

I really recommend building your own subtitle handling system for text formatting etc. b/c the built in system is very limited for UE4

[quasi jackal]

It don’t give me the blur I want

[tall escarp]

It's not hard you just need to get a handle on dialogue waves there's only a few variables to edit for each file

[quasi jackal]

I can do that?

[azure shore]

oh yeah sorry forgot it cant blur

[quasi jackal]

It’s all good

[tall escarp]

Pretty much any dialogue system you see on the marketplace either uses a variation of subtitles or manually displays text based on conversations from a data table

There's manual calls in blueprints for subtitles so you should be able to cobble something together

For the type of blurred shadow you're describing I think you'll have to do some work and visual trickery b/c I don't remember that being one of the rich text font options or anything

[quasi jackal]

I see

[azure shore]

man what a pain lol

always seem to run into problems with whatever I do with text

[quasi jackal]

it do be facts

I guess what it's true, the subtitle system is a nightmare

[azure shore]

oh god, can you not import morph targets on static meshes??

[azure shore]

I have just gone to all the effort to convert my character model to individual pieces so that I can have more control over customisation and stuff please dont tell me that was all for nothing

ok guess Ill ask the robot

https://tenor.com/view/yakuza-gif-18148683

[azure shore]

yeah I just dont know what Im supposed to do anymore

[hidden dew]

Anyone know why my UE editor is sometimes slow to respond? This kind of thing happens all over the editor. (Project isn't running in the .gif.)

The gif runs in slow motion for me (using Chrome), but ignoring that, it's the way the editor had fallen asleep for about a second before that Blueprint item woke up and jumped to where I was trying to drag it

[glacial pecan]

How do I "explode" or "expand" or get a proper static mesh hierarchy from a "USD Stage Actor"? (I want it to look like when you import an FBX into the level...)

[tall escarp]

It could be a lot of things. Make sure you're managing your caches properly including deleting caches when you get slowdowns.

[raven river]

[weary ledge]

Please help anyone that knows anything about the physical animation component: Link

[distant junco]

when i get near to the center of the Postprocessing volume the fog becames less dense, how can i fix it?

[tall escarp]

I don't have a specific solution lemme just say that I found the performance in physical animation in UE4 to be horrible and so was the responsiveness on transitions

[weary ledge]

Thing has been frustrating as hell to work with so far.

I love its concept, but its implementation seems to be problematic.

Its probably just me being shitty at dev again tho

can never tell

[tall escarp]

I spent a good month trying my best to duplicate what's set up in the advanced locomotion system in my game for NPCs to be more reactive to different damage types. Things "worked" technically but not nearly up to my performance standards

and it also would randomly crash my standalone game on steam and i haven't had that problem since going to a simplified ragdoll system

I just don't think it's well done in UE4, haven't played around with it in UE5 yet

[weary ledge]

Im in ue 5.4.3 source build

with what i've been doing

[keen tulip]

hi, im very new to unreal and have just been following tutorials and such to get the grasps of things. how would i go about editing the default values of this? for example on defeating an enemy.

[tall escarp]

Ah, you may get better help in the UE5-general channel for that then?

[regal mulch]

Not sure what you mean by that.

[keen tulip]

no worries the problem is fixed now :)

[urban oracle]

Hey!
I hope I'm posting in the right channel, I do not understand the issue I am having.

My ragdolls are glitched and sometimes freeze my game and I am not able to track down this issue
It appears randomly on some builds, and sometimes after launching a build that did not have the issue earlier

Unistalling the game from Steam and Installing it again solves this bug (I really don't get it)
The game is to ship for tomorrow's Steam Next Fest, if you have any idea on where I can look or what it could be, be sure to tell me 🥲

[tall escarp]

i really recommend (i keep saying this) having a robust print string system that you can turn on for finding out where the crash is likely being triggered, also look at your crash reports to see if you can tell what happened right before the crash

if the issue is specific to your project you're not going to get answers as good from people who've never played your game as you would from having an internal error printing system. it's just not the way to do things.

Forums/discord are for engine specific problems other people can reproduce easily and you need to have your issue narrowed down enough to ask correctly for that to be effective.

Good luck on the next fest though that's cool.

[urban oracle]

Thanks, i wish the game crashes, but it just freezes, so no minidumps :c

Hello everyone

Is that an advertisement?

[shrewd gulch]

I'm looking for a precompiled build of unreal 4.27.2, I was told I could find it here?

[spice ruin]

Is it not on the launcher?

[shrewd gulch]

nope, only the rounded out version numbers which is frustrating

4.27.0 but I need specifically .2

it's for payday3 modding

(yes people still play it)

[sharp hemlock]

Has anyone ever experienced, on 4.27.2, having the transform gizmos (rotate, scale, move) stop receiving hover/click inputs and consequently not working after playing around with actors on the level editor? Additionally, have this only happen to some actors and the number of actors where this happens increase over time?

[spice ruin]

If you install 4.27, it will get you 4.27.2

[frail river]

Hey all, does anyone know if this is the right way of doing something like this? Is it ok performance wise to call my custom event every tick even if the delay node says it is ignored? Or do I have to add let's say a bolean that gets set to true or false if the custom event is on cooldown? Would that be less costly in a strict best practices way?

[tough thicket]

why is imt when i make my zombies in the red circle the animations are fine, the are perfect no issues

but if i build navigation near the yellow circle

the animations are all messed up like constantly reseting so its always spazzing out

they do the AI stuff fine, its just the animations are messed up ?

[oak patio]

don't do a delay on tick

just use a timer

[frail river]

Timer?

I thought delays were timers 😄 What's a timer

[oak patio]

a timer is exactly what it says on the tin. A way to execute an event after a set time interval, that is normally looping

A delay is more "do this bit, then wait a bit before doing this bit", you wouldn't use it for this sort of thing

You want the Set Timer By Event node in particular

[frail river]

Thank you I will investigate!

[spice ruin]

[crisp moat]

is there a way to disable shader compilation completely using prebuild unreal not source ?

[oak patio]

Shaders need to compile, they can't not

[crisp moat]

i just need to delete old unused assets in one of the projects and everytime i do that shaders start compiling

[crisp moat]

logic behind compiling shaders for an asset that is getting deleted ?

[oak patio]

I'd imagine they have to decompile in case you're removing a material

Or a mesh or something

But no idea, I didn't write it :P

[crisp moat]

isn't there a commandline in place cpp would probably be void FShaderCompiler::CompileShaders() { return; } just saying

[oak patio]

But again, it's not that simple. Shaders have to compile

[jolly mason]

just found a solution to my last projects bottleneck, feels good man

yea no you guys are out of luck i need to talk about this, so my project for a while now has been a airship project, with modular parts, so every piece of flooring, every wall and every engine wing part were actors that were attached to the ships spine using attach to. this turned into a nightmare when those ships would move and each part had its transform calculated. not good for performance.

what i came up now is that each wall/ floor element, that makes up the mayority of all the parts, is one procedural mesh component
so i take a skeletal mesh, pose it into the shape of the ship , turn it into a PMC, each wall segment has its own material which means those would be its own section.theeeen i can use a sphere trace to get the face index and its corresponding material, and luck would have it the material section index is also the section index of the PMC so i can then update the section of that mesh and basically disable collision

imagine gmod blocks to be individual wall elements of a ship

not only does it change its visibility but also its collision

[tall escarp]

That's a good solution

[jolly mason]

Thank you 😄 I am so thrilled to work on it again

[tough moss]

Hello all ! I use a modding tool for longvinter based on Ue 4.26 source .. And after an update on the tool all item present in the game are white in the inventory and i cant interact with !

i would like to know if its happen to someone and if someone can help me, i can share some screen or come in call

It would be great if we could fix this before the devs, who are more focused on content for casual players.

[spice ruin]

We don't support modding games here.

[frail river]

Does anyone know why looking at my terrain from far away makes the fps drop to 20 😄

The only things visible in this shot is the terrain, I've deleted literally everything else

Going to ground level the fps goes to 120 😄

I can't find anything about this online

But for some reason looking at the terrain's lowest LOD is somehow more expensive to render than being up close and getting the highest LODs possible

Base pass goes crazy for some reason

[steep temple]

hey all! fairly new to UE development

was curious on if anyone has run into this issue on UE 4.26 with the web browser? I scale the actual widget but the view port doesn't seem to resize the page content

[tall escarp]

When you're at ground level how much of the terrain is occluded by view angle or elevation?

[frail river]

Most of it, but how can that be the cause, Looking from above I am looking at like 10k quads, at ground level and at lod 0 of the terrain there's easily 100k polys on screen

[tall escarp]

if most of it is occluded that's the performance diff. you'll have to analyze it but tesselated landscapes are fairly expensive in ue4

[frail river]

Also exporting its highest lod as a mesh and placing it in the world works fine from above

Yeah but it's the opposite of what I'd expect 😄 Highest lod works the sloweest 😄

Eh god knows what insane things are happening under the hood, I'll make a level LOD and replace the landscape with a mesh, of the land scape, that somehow works faster than the landscape

[brittle gulch]

Hey guys, do you know where I can find this plugin, or something similar? It's missing from Fab (like almost everything...)

[jolly mason]

okay whomst knows a thing or two about the procedural mesh component?

i have a plane that i offset along its normal, after some math i combine two sets of data into one section

the result is two walls, inner and outer

heres the issue tho. the collision is all whack

the outer side of the wall has correct collision

the inner side however, well...

my theory is that the create mesh section function cannot handle to create complex collision for these two planes

[jolly mason]

after some more testing it appears that the inner normals face the wrong direction

my first thought was to multiply the normal array by -1 to flip them but it didnt work

[tall escarp]

by "break tradition" do you mean intentionally post in the wrong channel?

[velvet oracle]

I don’t know which channel people prefer to see the kind of post I put in, I’m simply looking for help and got pointed in this direction

[tall escarp]

UE5 general and the materials channel seem appropriate for what you're asking

[velvet oracle]

uhp I see the problem now, i will correct this mistake - thanks

[jolly mason]

problem solved, heres the solution: not the normals make the collision or backface culling, its the triangle order, so reversing the triangle array of the inner plane did the trick

[cedar radish]

so im modding a game and one issue ive seen is that unreal only seems to load 1 buildata at a time. Is this just an issue with the game im playing or is this just unreal in general

[tall escarp]

Are you referring to lighting builds? You can handle multiple builds by using lighting scenarios

[jolly mason]

how to best handle many physics actors?
yellow spheres accumulating at the floor are place holders for the object that appears when you shoot off a wall element of the airship.

i have been stress testing my system and there were two things i noticed:

1. lotta actors = lotta draw calls
2. lotta physics actors = lotta ms

obviously in the end product it will never be possible to produce this many things, still id like to know some neat tricks to optimize this sort of thing

[tall escarp]

Just personal opinion after experimenting: don't have a lot of concurrent physics actors in ue4, instead manage how many you have at once to optimize the performance.

On my game I have hard limits for that and factor it into design

[jolly mason]

interesting, thats one way to do it

how to best detect them? have one big sphere around any ship and if something gets removed it checks how many are already on the floor? this might lead to some issues cause a "get all of type" seems quite costly

[tall escarp]

Yeah you'll have to program an efficient way to track them it's worth the effort if you want physics with good performance (I use it for ragdoll and some other destruction assets but the logic is the same)

[jolly mason]

i found a solution thats quite simple, inside my gamemode i added a function to which i pass a reference of the added module, if the length of the array storing the modules exceeds the threshold then the first element in the array gets deleted

[cedar radish]

The _buildata files that control the shadows, with the level streaming for the game only one a single shadow map can appear at a time

so if i have 2 lighting maps loaded at once, one wont have any shadows

[tall escarp]

Did you look into the lighting scenarios I mentioned?

[gray basin]

unless you obviously know the issue then reload with default map settings should be fine

[dense lance]

Hey , Is there any switch/Xbox developer?

[oak patio]

Almost certainly. You won't get much help however, consoles are under a strict NDA

[dense lance]

So where can I find some help I am a certified console developer but still I dont have much information about that

[oak patio]

You're limited to the dev forum for that console.

If you've shelled out the small fortune for UDN, I believe that's an option too

Console development is very much "figure it out" territory sadly.

[dense lance]

Actually, I don’t want any help that goes beyond the NDA. What I did was download the platform files and add them to the UE4 source code.

After compiling the engine:

I can successfully build for PlayStation.

However, when I try to package for Xbox or Switch, it redirects me to the Unreal Engine documentation portal instead of proceeding with the build.

[spice ruin]

Even the dev kit, how to use it and any inter-console issues are probably under nda, too.

However, I'd suggest checking your output log.

[dense lance]

Ok thank you

[sand inlet]

Does anyone know how to get the chorded action tied to an input action? This is for shortcut display.

[tall escarp]

When you're working with this rebinding and display stuff it's important to learn how to manipulate InputActionKeyMapping which is a struct.

Here's the documentation, from here you should be able to do your searches against the Action Name which needs to match whatever the Action is named in your project's Input Settings:

[sand inlet]

Great, thank you.

[patent dust]

i know this may seem really simple but its got me stressing for a few days now with a deadline coming up fast:
im working on an unreal engine 4.27 version project (ill put the version in case it helps) and i cant program a door being destroyed after collecting 5 collectables, can someone help me please?

ive tried searching up tutorials but i cant find anything to do with collectables and destroying an object

[oak patio]

You need to think less specifically in your hunt.

Destroying an actor is always going to be the same, no matter the condition before it. You can break down your logic into "if (number of collectibles collected) is equal to (number of collectibles needed), then destroy the door"

Once you break it down it's much easier to think about. Destroying an actor is simple, it's just the Destroy Actor node. So you're probably going to want an event in the door, that perhaps checks if the number of collectibles collected in is equal to the number it needs to open.

You're then going to want somewhere to track the number of collectibles picked up. This could be in many places. You might put it in your character. If this value persists across levels you might make a GameInstance class. Wherever you put it isn't of importance. What is important is that your collectible increments the value and destroys itself on pickup.

Your final step there is to signal to the door that the variable has changed, and the doors should check again if they need to open. You could simply get all actors of the door class and call the event on them if you wanted a quick and dirty method. Another option might be to have an Event Dispatcher in the place that has the number of collectibles picked up. You'd then want a function in that same class that increments the variable and calls the dispatcher. Then instead of your collectible incrementing the variable, it calls that function.

In your door's Begin Play event, they would then bind to this event dispatcher with their event that checks if the door should open.

Break down your logic into small bite-sized pieces that you can focus on separately. You're not going to find many tutorials, or people talking about how to destroy a door when collectibles are picked up. You will find people talking about destroying actors, or tracking global values, or having objects listen for changes.

When you really break it down, a collectible is the same as a pickup, is the same as a trap, is the same as a lava pit. They all do {thing} when a player walks over them. Generalizing and then adapting your results to your usecase is going to be much more useful

[patent dust]

Alright, thank you so much

[tall escarp]

Fwiw when you get stuck in really simple problems like this it's a good time to work out the logic on paper or a whiteboard. Sometimes you've been staring at a screen for too long.

[patent dust]

that makes sense yeah ive been looking at my pc trying to solve this quite a bit over the past few days its giving me a headache 😔

Anyone have an idea of how this would have been achieved? my guess is that they were loading in rooms as they entered each one but im not entirely sure https://www.youtube.com/watch?v=7J83QEww7wM&ab_channel=DeliciousWhales

[tall escarp]

it's done through sublevel loading, there's some Unreal Engine learning samples that do a good of breaking the technique down using overlaps/volumes that trigger the needed sublevels

[pulsar quail]

This is level streaming, yes? From what I can tell, the streamed levels are built in a certain spot, unless its possible to re-orient the other levels dynamically

[tall escarp]

Yes level streaming with overlap volumes check out the learning samples

[pulsar quail]

I understand the level streaming part as I've used it before, but I haven't seen the ability to reorient them dynamically. What learning samples do you suggest

[tall escarp]

Ah understood, what you're referring to is the endless rooms themselves, this old tutorial from UE should help:

https://www.youtube.com/watch?v=3om6yJiYMcg&ab_channel=UnrealEngine

I worked on a couple projects with dungeon/corridor spawning systems and some variation of this is what you end up doing, it's just a matter of checking for position and whatever gameplay triggers you have

[pulsar quail]

I found that video as well but I wasn't sure if using actors as level pieces was the best way of doing things, guess it is. Thanks!

[tall escarp]

I really recommend diagraming your system like a grid and coming up with the best method based on your needs. There's a couple different ways to do things from what I remember.

Basically it comes down to "when the player triggers the load/unload event what is the list of gameplay and asset considerations" and as always destroy your garbage.

For UE4 VR on quest 2, i'm having trouble building my project file due to what seems to be the virtual textures since it gives this error:

Package Fail: CompressedFormat == PF_Unknown || CompressedFormat == CompressedMip[0].PixelFormat
looking online, there was a solution involving editing the engine files, but it turned out to not work properly. Anyone else have this issue, and how to fix build issues?

[graceful shale]

Question: So I'm using UE4 and when I edit my resolution from small to large my portals stay low res, could I dynamically change the resolution with the players?

[gray glen]

You can resize your render target’s texture.
There might be a blueprint exposed function for doing so, but if not you can always just destroy the current one and spawn a new RT with new dimensions.

[graceful shale]

Also, I'm having the problem of needing to restart the editor every 30 minutes or so, if I don't the UI breaks. Is there anyway to fix that?

I'm morphing a large procedurarl mesh, 50k tris using complex collision.
Unsurprisingly, if I try to update its shape every tick with UpdateMeshSection(), I get a big performance drop. In the editor it will go from 120fps to 45fps once I tell it to start updating every tick.

What I'm surprised about though, is that when I do everything I can find to disable its collider with the intent of just updating the geometry only, I see no performance change at all. I would have thought that not-updating the collider anymore would have created a noticeable boost.

Same story with a 576k tri mesh. Goes from 120fps to 10fps, with or without the collider enabled (as far as I believe, anyway)

[ancient gale]

UE4 (4.27.2)

I try to make the sounds of footsteps, but for some reason I can’t hear them.....

[hidden dew]

ty for the response
What should I use instead? Runtime Mesh Component? Or is there something built into UE that's better than PMC at least?

[shrewd obsidian]

Not sure if this is the right spot to ask about legacy versions, but does anyone here have experience with 4.23? (I'm experimenting with it due to its HTML support).

My current project is mainly widget-based, but 4.23's scroll box seems to have a partly broken scrollbar. That is, you often need to click it a second time in order to go from the "hovered" state to the "dragged" state. Importing a working scroll box from a 4.27 project doesn't work, but opening the 4.23 project in 4.27 automatically fixes it.

Is there any workaround in 4.23 itself?

[gloomy iris]

is this using notify in the walk/run animation?

[bronze peak]

you want to use line trace and get physical material, so you can have different footsteps based on that. switch on enum

Hi everyone, hopefully this is the right place to ask a noob question. I am very new to the UE4 modding scene. I wanted to make a very simple mod where some numerical values in one of the game's .uasset file is changed.

What I did:

1. Use fModel to inspect the pak files of the game and export copies of all of the files
2. Use UAssetGUI to make changes to the target file
3. Create a folder with the same subfolder hierarchy as the actual game, then put the modded file in the folder such that the relative file path of the both the original and modded files are the same
4. Make sure the folder's name ends with the suffix _P
5. Using UnrealPak, pack the folder and create a .pak file
6. For verification purposes, I also unpacked the created .pak file and used a hex editor to make sure the modded file actually contained my changes
7. For verification purposes, I opened the .pak file in fModel and confirmed that fModel recognizes the changes I made
8. I put the .pak file in a mods/ folder that I created, and I put that whole folder into the /Steam/steamapps/common/{gameName}/BBQ/Content/Paks/ folder

The problem is, the changes I made are not reflected in the game. It's like my mods are not applied at all. I also have other mods that I downloaded from other people and also put them into the mods/ folder. Those seem to be working fine in game. Can someone kindly point me in the right direction? Did I miss a crucial step? Thanks in advance.

[oak patio]

We don't provide support for underground modding here. You're best off in an unreal modding discord 🙂

[fluid harness]

Can you give me some examples of that kind of server?

[spice ruin]

Part of not supporting underground modding is not really doing that.

You're effectively doing things that basically everyone here doesn't want you to do. If they did want you to do it, they would provide you with official modding tools or have some information on their website or something. Try google?

[karmic seal]

Hey guys! I recently converted my map to world partitioning. I built HLODs however they didnt get built for foliage despite enabling the hlod option in the individual foliage options. Any tips on how to get it to work? Otherwise is there a way to make foliage bot be affected by world partitioning?
Thanks!

[raven nest]

erm, is it possible to make Cascade sprites simply hold their spawned orientation? I don't want them to always face the camera.. seems like it's not an option? there must be a workflow..

[placid cedar]

If you recently re-installed windows 10 or 11 and are running into packaging errors related to the AutomationTool.exe, and its "access being denied", you must:

1. Enable Ransomware Protection Controlled Folder Access [Open Windows Security]
2. Allow an app through. (AutomationTool.exe)[Located here: C:\Program Files\Epic Games\UE_4.27\Engine\Binaries\DotNET]
3. Restart the Unreal Editor and try repackaging.

The reason for this is Windows has pushed updates that further protect system folders.

[tall escarp]

Are your particle's emitters set to use "Camera facing" as their normals mode? IF so you can try changing that to cylinder or sphere?

[raven nest]

this?

[tall escarp]

That or something similar IDK the composition of your particle system. Anything that's facing the camera, look for those type of settings in each module within the emitter and change from Camera-based to something else

If nothing is set to "facing camera" then it shouldn't be doing it

[raven nest]

hmm, yeah seems like something is screwy

it's been upgraded from previous engines so maybe I should try it from scratch 🤔

[tall escarp]

you can also disable each module to see which specific one is facing camera

[raven nest]

having two emitters active causes them to interact in weird ways

[raven nest]

same thing with a band new system.. I dunno if I'm missing something, my system is screwed up, or I am losing it 🤪

couldn't get the mesh emitter to do it right either

if I check Use Local Space I can see it at a flat angle but it's on the wrong axis 😠

[wraith frost]

Does anyone have any tutorials on how to create a party system like this where you can host a party and have people find parties ?

[wraith frost]

I ain't never got ghosted this hard

[tough thicket]

i would assume Steam servers would have some support

https://partner.steamgames.com/doc/features/multiplayer

if not maybe try hamachi or something because

someone has to host it and a vpn isnt free so

[tiny zodiac]

Is it really this painful to set up Chaos destruction in UE4.27?

https://www.youtube.com/watch?v=gbgBcvHVyq8

is it the same in UE5?

So basically you need to install a new engine version just for the Chaos ? what a PITA 🍑🔥

Isn't there a simpler lighter way to do this? I really dont want to install a new engine version just to have Chaos destruction in one project

I only need my building cube to break into different parts, maybe i can even do it in blueprints

oh there's fracture

Apex Destruction

thats all i need

simple effective, and no bloat 🫄

https://www.youtube.com/watch?v=4MaIhIBZq_A

this is awesome. UE4 💪 simple and effective

[worldly trout]

It's unusable, honestly, unless you only want the destruction to be purely cosmetic

[tiny zodiac]

hmm, what would chaos bring more to the table ? the debris have collision ?

for now yeah, i only need it to be mostly cosmetic because its for buildings destroying in an rts

but now that you say that, could be nice if the building debris hit the soldiers below

though i dont know if its necessary that much detail and accuracy, and im aware these things come with its performance cost

I can also damage nearby buildings and soldiers of the crumbling building by just getting the actors in the area

perfection is the enemy of rts games

from what i tested its amazing so far

so unless there's some performance benefit in Chaos, or something that is 10x better, i think i will roll with this one

[worldly trout]

The main benefit is hierarchical destruction that can efficiently be woken up and interacted with at any time, even cached simulations can be interacted with. That's the promise anyway, in UE4 however there was basically no collision option that reliably worked with the player capsule without major problems

in recent versions of UE5 it is in a decently usable state

I don't think it's any coincidence that in Epics main tech demo for chaos destruction in UE4, the player couldn't actually move the character through the debris field

[tiny zodiac]

🫡 got it

[tall escarp]

One of the weirder things I ran into (my game features Chaos as a game factor so I wanted to have high destructibility environments) was that if a character overlapped a destructible mesh at a certain stage it would launch the character in whatever direction they were moving at a ridiculously high rate. It also caused big problems for NPC spawn waves, etc. Generally a nightmare to work with imo

[wispy bloom]

did you manage to fix this ?

[strong lake]

Im trying to read default variables for assed created in editor. But I often get zeros instead

Some of them are valid, but most are not ;d

im dum

i convert fractions to int

[winged notch]

yeah chaos sucks I moved back to blast

[modest whale]

Does anyone know why the cable command is taking forever?

(and also the rendering part, but that seems to be something else I might be able to optimize differently or smth)

[dusty marlin]

Could u show GPU profile ?

[digital ginkgo]

Do I need Visual Studio Installed for me to build my UE 4.27.2 game which uses only blueprints?

[dusty marlin]

If I recall correctly, u need it anyway

Ok mmm just out of optimisation and could help u with frame rate, do u need volumetric fog ? And plus are u using a cable component ?

[digital ginkgo]

Thanks!

[steady dagger]

Hi all, I have a problem. playing animation of changing the scale of the object is tied to fps, for example, if 60 fps then the animation of reducing the scale is played normally. But if the fps is 5, the animation plays very slowly. what is it connected with? how to solve such problems?

[modest whale]

you have to multiply the speed of the anim by the global tick thingy (deltaTime)

idk how to do that rn but I'll load up ue4 and mess around till I can find a solution

usually the play anim shouldn't be fazed by fps, unless if maybe the play anim function is being called every tick?

prolly just make it play the anim once until it's finished

[steady dagger]

I created my own interpolation after update

[modest whale]

ok

[hasty mortar]

Sorry for the random tag, but I found you talking about mods for steam here. You say it's a pain. But is it also a pain if it's just modifying and adding json files? I've set it up so they're not packaged but are present in the game files, I'm just not sure what we need to provide so that users can make and share mods modifying those files on Steam.

[wild crag]

It's really not that bad, and most will never need to upload a custom engine build either, and just a uproject

the engine really honestly lends itself to this kinda stuff, given asset registry and all

[wild crag]

outside something short of making your own ui application in one form or another, you would probably just link them something like https://guifier.com/ to edit jsons, if they aren't tech savvy

[hasty mortar]

Oh but that's not what I meant. I was wondering whether we need to provide anything specific to make it work with the steam workshop? The file is quite easy to read and edit. They're different "Sandbox Profiles" and can also be created in-game with a clear UI. The idea is just that players could share these profiles using the steam workshop

[wild crag]

check out this https://partner.steamgames.com/doc/features/workshop

it's not that bad, specially if you're just doing some json stuff

[hasty mortar]

Okay great thanks for the link, I'll check it out 🙂

[azure shore]

since instances can’t move or be attached to anything, how would you make something like a rope for example? and I mean an actual proper physics rope, not cable component, the only way I can see is to spawn an individual actor for each chunk of the rope which seems wrong but would it be an issue if it’s just a simple actor used for that? I always seem to think actors in general should be avoided when possible idk

[tall escarp]

"actors should be avoided"
huh?

[wild crag]

most would use a spline actor for this

[subtle escarp]

Does anybody know if I can browse what's in Jedi Fallen Order .pak files with any standard archive software like PKZip, 7-Zip or another?

[oak patio]

You won't get help with reverse engineering in this server, it's against the #rules
You're better off in a modding discord 🙂

[subtle escarp]

I thought that's what the purpose would be used for, modding. I have no intentions of reverse engineering anything.

[oak patio]

to mod without official explicit support, you need to reverse engineer files. Those same techniques can be used outside of modding for asset ripping, which is why discussion of it is banned here.

Underground modding is not a topic supported here as mentioned. Asset ripping, reverse engineering and unofficial modding all fall under the same banner.

Plus, even ignoring all of that, such techniques are not things that the average developer will encounter, so you're better off anyway in a place dedicated to modding :P

[wild crag]

There is a discord for that specific game as well

[onyx viper]

hey guys how do i make drop down variable like this ?

[tall escarp]

Look up "combo box'

[spice ruin]

That's also probably a uenum.

If you just want a selectable value in the details panel.

[onyx viper]

no i meant, i want it to be a customizable variable from details panel

to be more specific i want to select either one of these options

destructible or ragdoll from details panel

[tall escarp]

All variables are customizable. As mentioned if you want a list variable use an enum that has ragdoll and destructible mesh as the two enum entries

[azure shore]

yes “I always seem to think”, I feel very reluctant to make more in some cases like this because I keep thinking they have some kinda overhead, but I guess if it’s literally just the necessary components it won’t do any harm

[wild crag]

It really depends on the situation but there is already an actor/component type for the behaviour you described, the afforementioned spline stuff

[pulsar swallow]

search for any germans i want to make a game and i cant pay u but the game will be great

[tall escarp]

lol

[pulsar swallow]

what

[azure shore]

splines for use with physics? again this was just one example, mainly wondering if just using more actors was ok

[wraith frost]

can someone tell me how to open a .ue4stats file ?

[oak patio]

no worries!

[spice ruin]

You don't know about game dev, but do you know about discord etiquette and reading rules?

[woeful linden]

Can you tell me how to call it? I just don't understand how to do it.

[tall escarp]

I usually do "make struct" after "break struct"

You're asking how to call it but your screenshot shows you doing a set which is not the same

[lusty star]

hi guys, does someone knows if is there a way to know if someone is talking (im using VOIP integrated is kinda meh)

[hollow dove]

Is anyone using a Version below UE4.26 and if yes, why?

[late violet]

i'm using 4.22, it doesn't randomly crash on my machine (ryzen 5 3500x and amd rx 6600)

[tall escarp]

I'm only using 4.25 bc the engineer I hired to build the back end made a mistake that would require a big rewrite to use the latest ue4 version. It's not by choice since some of the bugs are bad.

[frail river]

Hey all, does anyone know if there's a program that can apply a texture with an alpha to a high poly mesh, and bake that to a low poly mesh? I have an HD mesh with a lot of planes with an alpha texture applied to them, and I want to bake all that to a LD mesh. Blender can't do it, Substance Designer/Painter can't do it, and I even tried xNormal out of desperation 😄

[plush thicket]

does anyone know what im doing wrong? when i bake it it looks like the one on the right which is very wrong

when I want it to look like the one on the left

[icy bluff]

Does anyone know if its possible to mod the assetregistry of a packaged game? There is this dead game that I‘m running a private server for but we can’t add new content due to the Game ignoring the assets cause its not listed in the assetregistry.bin

Is there a way to inject something into it?

[oak patio]

Underground modding isn't something that's supported in this server

[wild crag]

Asset registry lets you scan new stuff in, though for iostore, it's current implementation with default packaging methods is frankly broken

though, you don't need to scan things into the reg for the game to recognize the assets, your issues likely are elsewhere, probably improper patch packing

[icy bluff]

game doesnt use iostore.
also i can load the assets they just arent recognized
they'll appear in the loaded in ue4ss
game just wont use them

[jolly burrow]

So my understanding is that you cannot use current versions of plugins if you are trying to export to html5 in UE4.23. Does anyone know if there's a way to access an older version of a plugin? (I'm specifically looking to use paperzd in ue4)

[tall escarp]

When I've needed older versions I check the official website to see if there's a way to get specific versions. If not I email and ask the dev if they can send it over. Usually if you can prove purchase they will if they have it still.

[jolly burrow]

Awesome! I will try it out thank you!

[tall escarp]

NP it's one of the main reasons I want to move to ue5 for future projects. Getting old versions of plugins is a headache.

[jolly burrow]

True! Im just using it for html5 packaging

[wild crag]

Your issue is not related to the registry

bad packaging/sig files I'd imagine

[sterile star]

Update:
I had to install an older version of mono:

cd ~/Downloads
wget https://archive.archlinux.org/packages/m/mono/mono-5.18.1.0-1-x86_64.pkg.tar.xz
sudo pacman -U mono-5.18.1.0-1-x86_64.pkg.tar.xz

And then I had to copy the bin and lib folders to their relevant locations in UE:

rm -rf Engine/Binaries/ThirdParty/Mono/Linux/lib/mono
rm -rf Engine/Binaries/ThirdParty/Mono/Linux/bin

mkdir -p Engine/Binaries/ThirdParty/Mono/Linux/lib/mono
mkdir -p Engine/Binaries/ThirdParty/Mono/Linux/bin

cp /usr/bin/{mono,mcs,xbuild,ilasm,al,al2,csc} Engine/Binaries/ThirdParty/Mono/Linux/bin/ 2>/dev/null

Afterwards I had to download this file from their official repo and place it instead of Engine/Build/Commit.gitdeps.xml. Setup now passes (make sure relevant scripts are executable). I am now having trouble with the GenerateProjectFiles.sh. It is printing a lot of

This is slow and dependency checking will not work for it.

but for many different files (my terminal is completely flooded with the number of warnings). The script passes, but running make eventually leads to the same warnings and an error:

Does anyone recognize this crash error regarding Virtual Textures?
We're trying to figure out the cause of this crash in our most recent packaged builds, using UE 4.27.2.

I only recognize that it's an error with the tile padding, but I have no more context as to what the actual error is implying the issue to actually be.

Our landscape RVT textures use the settings seen in the attached image.

Does anybody know of a backport of the ue5 web browser widget/ browser functionality backported to unreal 4 versions?
I am trying to have a desktop app, that can also be ran in browser, that can be ran as an editor utility widget, but ue4 4.27 and below cannot load said pages while ue5 can. I am hoping someone else was bothered by this and backported haha

When you add these to your environment variables

export UE_USE_SYSTEM_MONO=1

You can run make in the Engine directory, and it will build. It failed to build two files, which I will get to later. Upon running the UE4Editor I get:

I'm having some issues building my project, I get this error. As far as I can tell the plugin should be installed correctly, the one I'm using is: https://github.com/HoussineMehnik/UE4-PaperFlipbookWidgetPlugin

[spice ruin]

Any build errors? Are you starting from your IDE or the launcher?

[pallid knoll]

no errors when building, that error shows when opening the exe from the build

[spice ruin]

And how did you build?

[pallid knoll]

with the shipping configuration but it also happens using development config

And tihs happens when you run the packaged game?

yeah, it shows that error and then closes

[acoustic quarry]

Hi there!

I have the exact same problem as here: https://forums.unrealengine.com/t/hierchical-instanced-static-meshes-not-occluding-properly-what-am-i-doing-wrong/123226/4

Group(s) of instances in the HISM disappears while I can see them. And invert, stay visible when I can't see them. Randomly... Probably due to grouping/cluster tree settings.

If I disable the cull distance the problem persists. I haven't found a situation where this problem goes away.
I'm going to have to code my own HISM... 😭

Ideas welcome!

(UE4.27 to UE5.5 + occurs in several scenarios, even with classic foliage, at different scales, and with occlusion disable at project scale)

[acoustic quarry]

With the CVar foliage.DisableCull set to 1, and a forced MarkRenderStateDirty() on the component : no occlusion problem! But I can't do this every tick...

[tall escarp]

So my workaround for this issue was to not use hism for foliage. I instead use blueprints to allow variety in foliage that needed it (wind effect etc) and just created low poly meshes for every other foliage and painted them

[acoustic quarry]

So you use classical static mesh components?

Tomorrow I'll probably try to modify an ISM in order to add LOD support, and avoid HISM cluster tree and occlusion settings...
But if it's not efficient, I'll go with static meshes 😩

[tall escarp]

I had to. You might find better success but it was just too much for me to figure out and I needed to move on.

I reserved blueprints with static mesh components for anything I needed to modify at runtime as I said for things like dynamic weather

Hi everyone! Can someone help me to troubleshoot this issue I am having with attaching using the sequencer?

[main shadow]

what version of ue4 are you guys using? Anyone using a custom fork of some kind? Im looking to dip my toes into ue4, i dont specifically need any features from ue5 but is there any forks or plugins that are recommended for a more expanded feature set?

[pallid knoll]

Wasn't sure whether to put this in UE5 or UE4:

I'm having issues converting my project from UE4.27.2 to UE5.1.1

I've tried right clicking and choosing 'switch unreal engine version' and choosing 5.1.1, but it then won't open at all (when double clicking the uproject file is says "failed to launch editor", when opening it through the editor it just closes and doesn't do anything)

I did have a plugin, paperflipbookwidget which I tried disabling and deleting the files, but that didn't fix the issue

The reason I'm swapping is to make an online leaderboard, as I've found a tutorial for UE5 but can't find one for UE4, so help with either converting my 4.27.2 project to 5.1.1 or helping find a tutorial for a leaderboard for UE4 would be great

[main shadow]

wouldnt following the ue5 tutorial work the same way in ue4?

unless you interact with like niagara systems or some new features in ue5 it should work the same way

[pallid knoll]

it relies on a plugin that I don't think is available for UE4

https://www.youtube.com/watch?v=RQPI6cNNEaY

[main shadow]

is this plugin responsible for like the ui elements and menu interactions or like some c++ to blueprints code translator like these EOS plugins usally are

reason im asking because if it mostly handles ui elements then you dont need the plugin work in ue4, just open a ue5 project with the plugin installed and re-create it in ue4 if its in blueprints

[pallid knoll]

It's responsible for calling http requests, I've tried searching if that's possible in UE4 but most search results are just talking about UE5

[acoustic quarry]

I finally used an ISM coupled with Nanite and found myself with the same performance as the HISM, without the occlusion problem.

[tall escarp]

You're using nanite in UE4?

[acoustic quarry]

UE5 🙂

[tall escarp]

Why are you posting in UE4 general?

[acoustic quarry]

Because I can't find the ue5 channel 😂
And, I had this problem since UE4, and I finally migrated a few months ago. So it's not specific to the engine

[pallid knoll]

tick this, the ue5 channel will be above this one

[woeful linden]

I have such a problem, I have the interface menus appear on the level, I wanted that it would be the same on the settings, but I do not know how to implement it, while it was saved settings parameters

Trying this again, anyone recognize this UE4.27.2 packaging error? I can't find anything anywhere regarding this and as a level artist have no idea what it implies or where to even start

We use RVT for our landscape and blending objects with the landscape, no other virtual texture streaming being used otherwise

This error has only showed up recently after never being present for the almost 5 years the project has been worked on

[wild crag]

"UE4.27.2 packaging error?"
yet the log says
"UnrealEngine_4.26_Source"

[wild crag]

.

[manic pier]

Yes, after upgrading from .26 we never renamed the folder the UE source is repo'd into to avoid conflicts.

[kindred creek]

[wild crag]

Probably are just gonna have to check git diffs until you find the problematic issue starting

[distant junco]

Yo guys, did someone figured out how to setup android studio for 4.27.2? Cuz literally the official docs and a lot of tutorials didn't work for me, i always miss some files that i can't get (android.jar it's one of those)

I can't convert my project to UE5 cuz first i would lose a lot of performance, and a lot of stuff doesn't work properly after conversion

[molten lava]

i tried to setup my project for visual code, changed the option in editor preferences, tried to create a c++ class, which failed because i hadn't installed dotnet sdk 4.6, then i installed it and tried to relaunch my project and now i get this error (module name is project name):

googled this and the common solution is to recompile source, but how do i do this?

uuh ok, i might be horribly wrong, but i just opened project file in notepad and changed this:

to this:

apologies for image spam tho

[manic pier]

Yeah this is my thought as well, engine source isn't edited in this case, so I don't think there's a point checking the engine source in this case. For the actual project files we use Perforce, but I'm not sure what even to start looking at.
The only thing that has changed is that we use a larger map in comparison to before this error started appearing, previous build the error disappeared seemingly on its own as well, before returning again in the next build, and we don't know the reason for this.

It also only started showing up since a few weeks ago

after almost a whole year of having the project upgraded from 4.26 to 4.27.2

[tall escarp]

Did you open your project in visual studio --> select your project's parent folder --> right click --> build?

[molten lava]

nah i didn't
i found only cpp and header file in /Source, no .sln or anything like that
removing modules part from project file seemed to work soo.. ill try it if it breaks for real

[tall escarp]

The solution file is generated by right clicking the project file --> generate visual studio project files. Once you do that open the sln file to do the above steps.

I'm a little confused on how you're working

[spice ruin]

Rider doesn't need sln files.

Or you can open the folder as a project in visual studio code, etc.

Good morning. Does anyone understand why an FTest would be failing despite hitting the success condition?
It's just a bool branching to finish test with successful and finish test with failed.
looking at the log, it's hitting the failed condition.

does bulk edit works in eu4?

Hi, I am making a multiplayer game, and I was wondering if I could send over a packaged build of my game to my other pc using the unreal engine device manager/ project launcher?

If no better solution is available, you could consider using LocalSend to transfer your packaged build.

[magic wyvern]

Is it possible for a attached actor to somehow contribute to the root component for collision checking? Aka, I have a certain item actor that can be picked up that attaches to my player actor, is it possible for it to contribute to the player's collision blocking movement, does anyone know :)?

[tall escarp]

Just treat it like an armor system and run a function when picked up that attaches the items and updates its collision

[magic wyvern]

I don't know what you mean, but I've since found another solution. Thanks!

[deft coyote]

Making Armor collision is a headache if you are making it really realistic

[cerulean pine]

Heres my idea "Scratchbones": Imagine poker, only:

1. Instead of cards you have Scratchbones: little trapezoidal cube thingies made of ivory that are taller on one side, on which is a number 1-12.

2. Hand supremacy isn't pattern/match based, its pure addition.

3. Each hand is 3 Scratchbones, and they're handpicked instead of randomly drawn. Theres 3 rounds including a draw, betting stage and showdown, and the expended Scratchbones don't return to your options for further hands until all 3 rounds are complete.

4. With each hand of 3 a fourth Scratchbone is picked and put in a dice rolling cup. After each betting stage completes (assuming at least 2 people haven't folded) right before showdown, the cup is shaken and the dice dropped over the pot. The closest one to each player is subtracted from the value of their hand before the winner is decided.

5. The fact its a video game allows some fun bullshittery to the mechanics. When you play there are fidgets you can activate from a wheel, like scratching your head, tapping the table, shuffling in your seat, yawning, stretching, whistling or eating the food served at the table. At the beginning of each game of 3 rounds (the expending if all 12 Scratchbones), a player is assigned a random [Tell], which is a fidget that will increase their [Luck] score by performing it. Higher [Luck] tilts the chance of getting a lower penalty bone to roll towards you. It would be best if the rolls toward each player were scripted instead of physics, so it would be obvious who got what.

---- I want the game to allow extensive customization of not only fur/feather color hair/beard style and clothing/armor, but also allow vastly differing anatomy. Hence I imagine the pieces would move through the air on their own, and the hands of the various character skeletons would attach to them and use IK to make it look like its the character driving the movement.

Could someone point me to tutorials on how to set up each of the required systems?

Or what to look up specifically?

Also advice on the blueprint architecture would be nice

How concerns should be seperated and kept modular

[deft coyote]

You are thinking of making a game of it?

[cerulean pine]

Yes unless I get overwhelmed. Im open to collaboration and a smaller profit cut in comparison to others as long as I keep the rights to the IP (my fantasy world).

hands-on help of the technical variety would more than likely keep me from getting overwhelmed

It would certainly lead to an eventual release

look at this cute round birb and know we will be rolling in money coins

Youtube videos of cute animals rarely get dislikes

if so ur a monster

its also got sloth people, highland cow (those things with the hair in their eyes the internet incorrectly call yaks) people, kitty cat people, elephant people, mastodon people and mammoth people

people will love it

even if the gameplay is meh

[azure shore]

was this instanced mesh scaling problem never fixed? Ive found people talking about it 8 years ago and replies saying unreal team just isnt gonna fix it
first image is regular placed meshes, second images is instances placed on a grid

Im on 4.26

just slightly infuriating

[deft coyote]

Maybe something to be done with material?

[azure shore]

wdym? this was in detail lighting viewmode just to see it easily, theres no reason the material would offset the meshes

[deft coyote]

Mb I was confused

[spice ruin]

What even is that question?

[sonic drift]

im new to unreal engine

ive seen many youtbers complaing abt how ue 5 reduces fps

so im planning to make games using ue 4

can ue 4 give decent graphics

[oak patio]

This is false. Youtubers like to create controversy for views.

Anything new in UE5 that can eat performance can be disabled and you can optimise your games. The engine doesn't do the optimisation for you though, you need to put in active effort of finding the right combination of settings as well as optimising your assets and gameplay

[sonic drift]

hmm i see thank you for you advice man!

i tried using ue 5

i made a basic fps game

[sonic drift]

is it diffuclt to optimize games?

[oak patio]

Absolutely. It can take a lot of effort, profiling, iterating, testing on different hardware.

That's not to say it's not doable, it's just something you should be aware of 🙂

[sonic drift]

alright man again thank you for the advice 👍 😃

[tall escarp]

Many of the features Epic is pushing with UE5 reduce FPS and make older machines obsolete. If you disable a large number of those features there isn't a huge difference between UE4/5 imo but the changes they made are enough that you should make a new project in UE5. Enhanced inputs and the improvements to sound for example (Sound Cues kinda suck)

There's also a fidelity issue, if you chase the UE5 realism look you drastically increase dev time and assets like animation and voice acting need to match that fidelity, which is why so many UE5 games feel "off" or don't come out at all

[sonic drift]

Hmmm I see, I'm just a beginner do u recommend using unreal 4 or 5

[tall escarp]

"you should make a new project in UE5"

[tough ridge]

That's not entirely true

Things like the physics system has changed from PhsyX to Chaos and that's not easily changeable

[oak patio]

True, but physx being removed is never the focus of those videos :P

[tough ridge]

Chaos performs significantly worse which is the point

Anyone know why my custom depth looks like this?

When I move the camera it randomly gets blocky

For reference, this is on unreal 4.15 😄 ((Modding an old game)) So maybe this is just a bug in this old unreal that got fixed later?

So this translates to, is there anything I can do to get it to work 😄

We don't really support modding.

[haughty slate]

Just trying to understand the garbage collector. I am prototyping something involving render targets and for now I am creating a new render target each frame (this will not be my intent with the finished product, just for now I am experimenting) and I noticed that when I check the name of the created render target (canvas), it's number increments each frame (rendertarget, rendertarget1, rendertarget2 etc).

I read up that the garbage collector should destroy these so long as there are no stored references to it when the next tick begins. I was storing a reference to he render target so at the end of my code I set it to null. I also set the material to something completely different as this will also ensure that the garbage collector does it's thing.

Problem is (at least I think it's a problem), the render target's number continues to increment each tick - which leads me to believe that the garbage collector is not destroying the previous version of the render target.

Am I correct in assuming this is the case because the number keeps incrementing? Any general advice regarding good practice in ensuring the garbage collector can do it's job?

[spice ruin]

The GC runs once every minute or so normally.

So for up to a minute your render targets will sit there, taking memory.

You can force it to run if you want by sending the obj gc console command or setting the GC.somethingsoemthingEveryFrame console var.

Or I'm sure there's a c++ method somewhere too.

[haughty slate]

Ah that's good to know that it's every minute or so. If garbage collector is running, am I correct in thinking that after a minute has passed it should start incrementing the number from 1 again?

So for example, if the current increment is 100 then and then the garbage collector kicks in, shouldn't I start seeing RenderTarget1, Rendertarget 2 again?

[spice ruin]

Possibly?

I think so.

[haughty slate]

I would have thought so but that doesn't seem to be the case, so maybe I haven't completely expunged al lreferences

The obj gc console command I can't seem to find, when I type it in it wants to prefill Object Classes

[spice ruin]

Maybe it wasn't in in the version you're using.

[haughty slate]

I'm on the latest version of UE4 but not to worry, I shall do some google-fu relating to the console command

Interestingly enough, the numbers continue to increment but I noticed that after 1 minute and 11 seconds the memory use - having climbed up to a whopping 11gb - resets to about 300mb! So garbage collector must be working, it just doesn't reset the increment count!

[bleak glen]

im using 4.27.2 and i cant design vehicles with 3 wheels it just drop to ground vehicle physics doesnt work
but in ue5 i can create vehicles with 3 wheels

is this limitation in physx?

[haughty slate]

You can absolutely make a 3 wheeled vehicle work if you're setting it up manually. I don't have any experience with Unreal's vehicle tools (I don't even remember what they're called) so it's possible that is a limitation with the UE4 version but I couldn't honestly say.

Hello, I need help, not sure if this is the right channel. UE keeps deleting all compiled shaders forcing me to recompile. This is getting extremely annoying and it’s impeding my work tremendously. I’ve set delete unused shaders to false in baseengine.ini but this doesn’t seem to work. UE just deletes my shaders after some time and that’s it. I've just compiled shaders and made a build a week ago and now I launched my project and it's compiling them all over again which will take hours. I have a lot of free disk space so that's not the reason. It didn't happen before and now it seems to be happening more? Like 3 times in the past month it's just crazy...

There’s no direct compile recompile option for an entire folder in Unreal 4.27, however, what you can do is right click the folder in Unreals content browser and click Asset Actions > Reload, that will refresh all the assets, but not recompile the blueprints themselves

You can also compile all by going to Window > Developer Tools > Blueprint Compile Manager, and in that window clicking “Compile all”

[sick escarp]

Nice, are you aware if it just compiles things that are not compiled or if it will recompile? I don't dare doing it for fun atm if it's every single thing 😄

hey all, my brain's short circuiting. can someone give me some keywords to google? i'm trying to give my first person character some animations. i don't want them all to just be a 1 off, where it plays the animation and then refers back to its default state. sort of like skyrim, i want to be able to change between a state of holding something, sprinting, idling, walking, etc. which all require an animation to keep looping until something else changes. is it behavior trees that i should be using? or something else?

[oak patio]

the animation blueprint

[tall escarp]

In your animation blueprint there's an option to toggle if an animation sequence is looping or not. The thing that changes varies from booleans to any enums you'll have to write that logic or just use a template to start.

Hello. I'm using unreal engine 4.27.2 and I'm trying to import an alembic from blender. ChatGPT says it should have a "export as curves" option but I don't see it. I've tried various settings and unreal throws an error and doesn't import and says to see output log but there's no error messages it just fails

it said if it doesn't appear as an option it's because I'm not actually trying to export curves but I am actually doing that so I don't know. my guess is that chatgpt is just wrong here anyway. But at any rate it still fails to import the alembic even though I can import it back into blender fine

[placid dirge]

Like this?

Widget Switcher

Border above that

verticle box above that

border above that

@rustic panther is this the necessary info?

[rustic panther]

ya, lemme see...

oh is it fixed in the last one?

[placid dirge]

ok cool

no its not fixed thats without the padding i added

[rustic panther]

oh well then you probably should add the padding somewhere else

or some other way

[placid dirge]

you can see the "next" button is way in the bottom corner out of view, it should be in the greay box's corner

thats the goal at least

[rustic panther]

oh ok

[placid dirge]

if i add padding to either of the WBP's there it moves the other element so i cant align it

[rustic panther]

it's kind of hard to understand the problem just with all this

[placid dirge]

yeah sorry im not sure exactly what info to provide because im not sure what is wrong. the other elements are working fine...

[rustic panther]

you should probably be nesting the text box element and the next button element onto the "Name" element

[placid dirge]

that doesn't seem to work, the name element is it's own thing. The border Im nesting under is the right size and in the right place, it's just that for some reason the things nested under it aren't complying to that area correctly.

the elements in the widget switcher are aligning to the bordes top left corner as it was an entirely new canvas, i think

i think the problem stems from me following a ue5 tutorial when im using ue4, im assuming some behaviors arent the same. everything else has worked though, this is the only discrepancy.

[rustic panther]

possibly, you can add widgets to other widgets with something called a "Named Slot" btw maybe try that out

that might be a UE5 thing though I don't remember

[solid holly]

should I name these as T_Example or Image
or do I leave em like that
(asking in case I work on a larger scale project)

[tough thicket]

im colliding with something in my cooked game after uploading to steam

its fucking my camera and i cant move and neither can my zombies

never had this issue before

my car can move cause its set to flying but the camera still gets pushed forward to the start of the springarm

[tough thicket]

oh i figured it out

was my fucking outline mesh attached to my skybox

[placid dirge]

anyone have experience with Ultra Dynamic Sky and can tell me why my height fog density isn't changing with this function?

[rustic panther]

if you search "Set Fog Density" in the UDS blueprint you'll find out that it's being set on tick, so if you try to change it the change will be overwritten

you have to change the variable that sets it to whatever it is

if you change the density with whatever variable you're changing it with that's the name of the variable you want to set

so you might try changing "Base Fog Density" instead

or "Scale Fog Density"

not sure if the UE4 version of UDS has these variables though

but you should be able to figure out which one to use

[placid dirge]

thanks qwigs, thats very helpful

doesnt seem like the ue4 version has those, I may try decoupling the set fog density from tick but i think that will cause other issues...

[keen thunder]

Is there a feature that allow me to "skip/fast forward" physics simulation?

[frigid gate]

Hi I have a series of line traces that simulate a bullet trajectory and I have a niagara system that spawns a particle with the same variables such as velocity, drag, mass, etc. But for some reason the particle only seems to line up at the beginning and end points, being slightly off on the arc. Any insight on why this is and how I can fix it would be great. I can share a video if needed

I would assume it'll break the time of day features

Hey @rugged siren big apologies for the ping, could I ask you a question in DM's? It's not something that could be talked about here but I couldn't send you a friend request.

[rugged siren]

Sorry I don't answer 1:1 here, I just join in discussions from time to time. What kind of question is it? I can redirect you to the relevant business email address.

[mental goblet]

Understood, It's related to development stuff, just not something I'd like to ask in the server, would definitely appreciate if you could redirect me

[rugged siren]

you can email [e-mail] for business related questions, but if you just want development help you're better off asking in public here or finding someone to consult for a fee

Can I get some help with stencil depth? This is my blueprint (the end of it anyway, I don't wanna post the whole giant thing), it works for the most part, applying the PP effect only to static meshes with the custom stencil value of 1, the problem is that the effect's outline is visible through any other SM (tables, floors, walls, mountains), unless that SM has CustomDepth Pass enabled.

[steep marsh]

for the ue4 version there is a Fog Density Clear and Fog Density Cloudy from what i remember

hey can somebody help me with something?

I want to make ark thumbnails with blender, but im having trouble extracting the uasset files i need for it

Good luck!

[oak patio]

I am curious though why that's needed, ark ships with a devkit

[long tusk]

devkit is over 700 gigabytes

or does it come with the game?

by default, that is

[oak patio]

No it's not
https://devkit.studiowildcard.com/getting-started/installing-the-devkit

[long tusk]

how long ago was this website updated?

[long tusk]

because epic games launcher is telling me otherwise

[oak patio]

Which ark version are you trying to mod

The older mod kit should be much smaller

The devkit has everything it seems, so yeah that website is probably outdated

[long tusk]

i wanna do ASE.

[oak patio]

the modkit might do it from what limited information I can find.
If it doesn't though, just use the devkit. I know it's nearly 700GB, but the official tools are there for a reason

[long tusk]

i see. and does the mod kit require the base game too?

[oak patio]

Doesn't seem like it

[long tusk]

im gonna uninstall ark and download the modkit then to test it out

you probably want to constrain the rotation amount of your camera so it cant look inside the mesh. Most games you can only see the tips of your feet or just your legs. Looks like you are looking down really far

[haughty slate]

Running into a frankly bizarre problem. I have a very simply project where I test prototypes - no marketplace extensions or assets are in use, just a blank project with no starter content and my own blueprints.

At construction script, I am getting component bounds of root (which in this case is a simple cube) and storing box extent to vector variable of default 0,0,0 rotation; this is used for a few things including box trace half size and also determining boundaries of the cube's face for determining where abouts an impact point from a colliding actor hits relative to the edge of the face. While using component bounds won't work for cuboids as it will still define the bounds as a square, the detection methods I have built will work for cuboids - component bounds is just a quick way for me to get to test this prototype.

I didn't realise that while the game is running, if you manipulate the actor's transform in the editor it will "refresh" the construction script, which overrides the initial box extent variable. If rotating the object, the new box extent does not give dimensions that conform to the new rotation because of how component bounds are determined.

Ok fine, so I move these nodes off the construction script and onto EventBeginPlay in the event graph. Using debugger, I confirmed - as expected - that EventBeginPlay will not "refresh" each time a transform is applied to the actor. However, if I rotate the actor to a 45 degree angle on any single axis, somehow the box extent variable is getting set to it's default value of 0,0,0 even though there is nowhere else in my code that this variable is being set.

So.... wtf? To make matters even more confusing, if I set the variable to public then it stops being reset to default value. Shrodinger's vector then, if you look at it it behaves as intended. If you don't, shenanigans happen.

Does naybody have any idea what is causing this? How coudl anybody work reliably with this engine if it exhibits behaviour like this? It would fundamentally break the game if the engine just forgets what a 3D vector should be.

Slight correction: 45 degree angles aren't the culprit, it's actually if I manipulate the rotation of the object in the editor window in any way other than using the rotation widget. Rotation widget does not reset the variable, but typing in andpressing return or dragging teh cursor over X/Y or Z does reset the value.

Same happens if I plug in a set actor rotation node, make the variable public and manipulate the same way in the editor window: Variable gets reset to 0,0,0.

[spice ruin]

The construction script executes any time you do anything.

[placid dirge]

Ok figured it out, Incase anyone else has this issue. I just put the collision onto the enemies instead of the player and that seems to work fine, I just have to destroy it when they die so it doesn't interfere with the ragdolls.

[modest whale]

Up until semi-recently ago, my ue4 project has started crashing after the project is done loading, and happens when the log window pops up, usually freezing and then crashes. Then it give me the WorldContext error, and I can't open it for awhile. Anybody know how to fix it???
Also, this time i tried to edit the binary data (whoops big mistake) after actually restoring it back, it says to check if it's the right type. Also, it gave me a breakpoint in the set code in engine code.

here's the trecent crash log (idc anymore i've)

I hope no other money beggars give me a half-assed response from chat-gpt and then ask a large amount of money from my parents or friends or some bs.

I might lose years of work but whatever

[modest whale]

Ok I fixed it

sort of

I reverted a function library back to remove that worldcontext error

but a random plugin kept trying to retrieve incorrect data

so I disabled it

now to add the functions back in

is there any reason that scaling up a model would make its collisons inconsistent? Im using a mesh trigger different audio is regions around my level but I have the mesh scaled up 500% and it isn't working consistently.

Im using "complex collsions as simple" if that matters

since GitHub doesn't allow you to push files over 100MB (even if you use GitLFS, it has certain restrictions)

I need one specifically to work with UE

[oak patio]

Azure

But literally any source control can work with ue, it's just a bunch of files

[toxic berry]

the problem is the 100MB limit

[regal mulch]

Azure + P4 I guess. Don't know the free instance limits. I started my whole journey with P4 hosted on a 5€/month droplet. There are less important things to cheap out on tbh.

[toxic berry]

Thing is, I'm gonna be the only one using this

I'm deciding to make a repo so that I'll be able to easily test stuff out with 2 computers, without having to constantly copy over the whole project

I won't be needing testing on 2 different PCs that frequently, but still annoying to copy over the whole project 😅

You should be using it to not lose your whole project one day. Not because you need it on 2 PCs

Hello. Does anyone know a way to change the global font at runtime? I have 2 different game styles in my game that use all the same UI. When swapping between the two game styles I'd want the font to change as well. Is this possible?

[haughty slate]

Anybody have any idea why UE4 is clearing my entire array when I remove an index? Array of 3 vectors (0-2 indexes): If I remove index 2, I get to keep 0 and 1 , which is of course what you'd expect. But if I remove index 1 it takes 2 with it, and if I remove 0 then it clears the entire array.

Apparently this is standard when working in C++, but I'm using blueprints where (again, apparently) arrays are actually linked lists, so you should be able to remove an earlier index and everything else gets bumped up. I know that's the case because I have done it countless times before.

From what I've said above, it should be obvious that the array is not getting cleared anywhere else. If I delete the remove index node, the array maintains all items and number of indexes.

Is the engine crapping out on me here?

[spice ruin]

Show code

[haughty slate]

And just like that, I finish writing this question, go back to UE4 and simulate (without changing a single god damn thing) and now it's behaving correctly. I swear this isn't the first time the solution to an odd quirk was to come on here and bitch about it. Wtf is going on? Is this engine just horrifically unstable? I am doing experiments on event graph that is full of code put to one side here and there, could this cause problems if the bp editor is trying to render too many nodes or something?

[spice ruin]

The engine (with tarrays) isn't unstable.

Using it impropertly can lead to instability. Such things include: not using the correct api, activating hot reload or live coding, if using a c++ project, not launching it from your ide. And so on.

[haughty slate]

This is as vanilla-arse a project can be, no custom api calls or anything. I'm using blueprints: I'll write some code, compile it and then simulate in the main editor window to test. Does this constitute as hot reloading or any other malpractice?

Like I said, this particular event graph is a mess with lots of disconnected nodes as I try things out - but there's not currently a whole lot going on with what is connected. As I experiment, everything is happening on event tick - so there aren't any overlap events or anything else triggering and overwriting any variables. It was reporting incorrect values, I opened discord, asked the question and without changing a single thing, it's working again.

[spice ruin]

No. They're basically c++ things.

Just so you know, if you do "array -> remove index 0" on tick, it will remove every value over 3 ticks

[haughty slate]

Of course, this array is built earlier in the code (on the same tick) - so every tick it is rebuilt and then index removed later down the line

It's doing it again, this time as soon as it's been set

omfg it is user error after all. It always is! I had a similarly named array that was being set earlier on but not in fact this one. SO of course I was checking after some frames had past and the array has been obliterated. I hate my brain.

heya, trying to make that heli into a mod for deadside, everything is working appart from 1 thing. the heli flies up and down no problem. but when i try to roll or pitch it, it sets the rotation back straight up. as result, it fly really really slowly, and is stuttering hard because of the tick resetting it does. at first i thought it had to do something with server RPC, but after trying it doesnt react at all on RPC. in deadside the player isnt possessing the vehicles but instead attachcing the actor in the vehicle and sens the input from the character to the vehicle. any advice to make it roll and pitch without resetting the rotation? and to check wether it was the character or not. i made it that i remote controlled the helicopter without attaching/entering the heli. and it does the same thing. so it must be something in the heli bp but i have no idea

[oak patio]

Because that code won't make much sense. What you're intending to do is check if the object is of the correct class, you would do that by either checking == on the object's class, or by casting the object.

What you're doing there is checking if an instance of an object is equal to an empty object, which it won't be.

Can someone explain the sorcery going on in this old flash game and if it's possible to do in Unreal?
The dev somehow created a transparent cutout at runtime using the font's internal outline. I'm 100% the effect is done at runtime, the original font is untouched in the game files as you can see on the left.

[delicate dirge]

The Flash game is just using the font as a mask at runtime, not a special font.
In Unreal you can do the same with:
Material alpha inversion (text alpha → transparent cutout).
Stencil buffer (draw background only through glyphs).
SDF fonts for more flexible runtime effects.

So yes, it’s fully possible in Unreal. ✅

Hello guys a tiny Question it is been a while I am developing a Game which is Like Assassinscreed but in a Ghost in the Shell Themed World
I´ve Also added a sand box mode which players can Edit the Environment Real time and Add quests and Enemies as well
but here is the Problem i am having.
for saving the Worlds that players make and Loading them there is no Sufficient way to save each actor and its properties.
I have to Save eg. the Transforms and Actor Location for each type of object Pool and then Sort them Manually in Loading Graph so they can load correctly and have no collision issues so Parkour can Detect them Realtime without Problems, does anyone have this Idea on how can i save/Load Static/Skeletal/BP_Actors as a whole in Realtime?
C++ or BP I can do both thanks.

[tough thicket]

i use 2 save games and have no issues

i load save game Main which hosts all characters on it then each of them their own saves

its hard to read what you write

but it sounds like the problem i had when generating my endless city streets, where you would never load up the same street again because you had to save the formation of the streets

What I am trying to say is that I can’t save around 500 different actors and load them efficiently, but this is a must for sandbox mode so that players can load their levels.
The saving system is not efficient because Unreal’s saving method can only save variables such as transforms, etc., but not the full object hierarchy.

[tough thicket]

yeah sounds like the same issue

i actually didnt get that far though i stopped when i couldnt save my XYZ grid

[oak patio]

Yeah there's not much way around a c++ save system for things like this

[inland epoch]

Thanks guys i will share the codes if i reach an answer.

[oak patio]

Tom Looman has a great starting point for a save system, it should be fairly easy to adapt to your needs

[inland epoch]

I will check it out thanks a lot

[loud berry]

anyone here? just have a general question about event overlap begin/end?

[radiant cipher]

Can I manually install and use OpenLand in 5.6?
Even just a few components like rvt setups?

Hi, I am new to unreal engine 4.27, so I have to work with modifying the landscape mountains(https://fab.com/s/8ec2cfab70af), as part of ML project data collection. I am also adding airsim to it, with this guide(https://microsoft.github.io/AirSim/unreal_custenv/), so what I am facing , if I create a new project in unreal editor with no starter content and then I go to epic games launcher>unreal engine>library>fab Library and add it to the project, I am seeing two .uproject and two .sln files, how to over come it. I am attaching the photo of my project folder

Hello, is it better to use blender version 3.6.5 when exporting to unreal 4.27
or it does not matter much?

[sick junco]

you don't have to use any specific version of blender to export files for unreal engine 4.27, or any version in particular.

[sick junco]

here i have an older version of blender where i have exported this generic box and put it into unreal engine 4.7

here i have a model from a newer version of blender

[real pine]

When saving a project, will there be significant differences for 4.27 and 5.6+ when they are doing the packaging?

[gray basin]

Any good microsoft access alternatives ?

I want to switch to something better

[paper island]

May not be the right channel for help, but kinda battling with this one. I changed some things within a level ive been working on, and now i have a pretty bad issue where i cant preview/play the level without a crash or delete any asset. The error is: Assertion failed: ReaderPos + Num <= ReaderSize [File:D:\Build++UE4\Sync\Engine\Source\Runtime\Core\Public\Serialization/BufferReader.h] [Line: 53]

According to google it has something to do with some dependencies? Or some confusion in unreals memory of a certain asset or corrupt asset or something?

[neon bough]

try duplicating the level, if you are lucky it will ignore any bad items and you'll be able to use it

[gray basin]

@oak patio ?

I am planning to include online leaderboards for my game and not just cataloging my game assets

[ocean moss]

Why is the gpu lightmap doing this? I cant explain whats happening other than there are trees and you can see some of their shadows but for some reason it only goes so far. not only that but objects that are lit also have the same issue. Its like the lightmap issue applies to the realtime lighting as well. Oh yeah. lightmass importance volumes dont work, Disabling and re-enabling Dx12 doesnt work, and not even Uv settings (landscape uvs) seems to be a fix.

Is there some way I can set the Montage Section start times by typing in a frame number rather than having to scrub?

Additionally, is there some way to make the animation scrub button not overlap the Montage Section scrub button? I'm having a problem where I want to grab the red animation button and scrub across the montage, but whenever the red button overlaps or is near a blue Montage Section button, it is invariably the Montage Section that will get scrubbed. This is very annoying and I would like to avoid it.

Does anyone have any advice or experiencing modding games in Unreal 3.
Would unreal 3 be similar to Unreal 4 modding?
I am trying to mod a game called subsistence.
I am trying to just add a simple recipe for crafting in game.

I did not see any tab for UE3 to post this in.

[oak patio]

UE3 isn't really discussed here because it's a much much smaller niche. Unfortunately modding games that don't have a modkit is also not something we discuss here.

[inland epoch]

Hey guys, this is a game I’ve been developing for a few months. It’s supposed to be like Assassin’s Creed, but set in a cyberpunk-themed city.
Do you think the climbing and parkour system has enough momentum, or should I change it?

[prime flare]

The movements are way too rigid, as you say it's a momentum issue - there's too much stop/start

Unrelated, I'm working on a racing game and noticed that the controls feel "heavier" when the framerate drops, like the radius to turn corners sharply decreases... Is this normal, and is there any way to make it constant without locking the frame limit?

[neon bough]

do you account for delta time when applying steering from input?!

[prime flare]

Do I need to use more than the input axis value? This is what I have...

I have the input going into the function in the second image, then through the Lerp... The != check is just to prevent movement when there's no velocity

EDIT: Promoted Event Tick's float and multiplied that by the steering values and it seems to have worked, thank you!

[latent stream]

I'm trying to get it to so part of the screen does not render to save performance. I want to permantly put a UMG Widget in the that area that does not render. Think the original doom or other similar old PC games that had a part of the screen that was purely UI. I have been struggling to do this and want to know if this is even a good idea or if it is feasiable without highly intricate work.

[drifting kettle]

hi! is there a place i can ask for help when it comes to ue3?

ik ue4 is the one that ppl are using rn but i rlly need help for ue3 😭 asking bc it doesnt seen right to ask ue4 general abt it

[tough thicket]

its fine but some kinks between animatinos

[tough thicket]

you could use a render target capture material

im not sure

Hi,
Can someone help me with this?

My physics asset is not correctly setup, I am getting wiggling arms

[inland epoch]

yes i had the same Idea i fixed them last week.
the faster the player is the better it looks

[plush yew]

hey, Is there a programmer who could help with programming the game? If necessary, could we agree on a possible payment?
(If anyone is interested, please send me a private message.)

I apologize profusely,

Hello, I've been seeing a bunch of discussions about companies and individuals still using Unreal Engine 4.27 to meet performance targets. As a person interested in learning Unreal Engine more, should I stay at UE5 or give 4.27 a try?

[oak patio]

UE5 for sure

Read the top pin 🙂

[sterile oyster]

Oh I didnt realize about the pin, thanks for pointing that out 👍

[oak patio]

No problem!

[reef lava]

Got a bit of a strange question here regarding materials in UE4. I've been in the process of converting a Synty Polygon pack to ue4 from ue5 for one of my older projects, and I've come across some expected issues with things missing from ue4 of course that are now present in ue5. For most I have been able to work around effectively so far, but I am unsure about this part where a switch node is used for the overlay texture in ue5. Where ue4 does not have a switch node. Does anyone have any ideas of what could be done here to substitute for this? I am not super well versed in materials, but I know enough to get around most things, but this one's got me. Thanks in advance all.

[narrow osprey]

Well done, man!
Loved your work, this is really good…

If you wish perfect your work just make the transitions smoother

[gray basin]

Has anyone made their own attempts of building their own DRM ?

[oak patio]

It would be quite pointless. If a company dedicates millions of dollars to making something as ironclad and intrusive as denuvo and that still gets cracked, the average dev has no hope

[restive ingot]

Where can i get help with packaging

I keep getting this error which is stopping me from packaging my game

[spice ruin]

I would try verifying your engine.

[restive ingot]

This did not fix the issue

[spice ruin]

Try asking in #packaging

Though I would try packaging a fresh project to see if it's something relating to you or it's a general issue with the version of the engine you're on. Or perhaps your setup somehow.

[restive ingot]

Alr, thank you

[analog ridge]

someone help

[gray basin]

I don't care too much if the DRM gets cracked

It is so I can store achievements and update the game when it changes.

[oak patio]

That's not what DRM does, DRM basically is about making sure your game and it's assets don't get cracked

[white tulip]

Hello everyone !!! I’m currently playing SCUM and I’d really appreciate some help with tweaking my engine.ini settings.

I’m trying to optimize visuals and visibility — things like better clarity, smoother edges, and less visual noise.
Does anyone here have an updated list of working commands or personal tweaks that actually make a difference in 2025?

Thanks in advance for your help 🙏

[restive ingot]

Yeah turns out a function which i copied and pasted from one of my other projects somehow duplicated the 'world context object' input and was causing problems, its now fixed and the project packages normally, thanks for the help :)

[autumn basin]

is there anything i can do about the bugs in ue 4.11.2? the epic install is all sorts of messed up and i cant seem to be able to compile the engine from the source code (having issues generating project files)

[gray basin]

Then what it is called ?

[oak patio]

I don't think it has a dedicated name for what you're talking about.

For storing achievements remotely, that would be the purpose of the sdk for whichever platform you wish to launch on. For doing it locally, that would be the purpose of a save system

For updating the game when changes are made, that is handled by the platform you are launching on, however sometimes games use their own patching systems to skirt the review process for updates (I do not reccomend this path if you're relatively new to development, or don't have a decent funding net and legal budget)

[gray basin]

Can you answer this

I pinged you back then you didn't responded

you've said ms accesss wasn't a good database software so maybe you know something better.

[spice ruin]

Literally anything? 😛

[grand prairie]

guys why do I get this issue

[gray basin]

I want to switch to a new database software, ms access is behind the others.

[gray basin]

Please check my replies

[oak patio]

i do not know of anything better

[gray basin]

Thanks for responding to a nearly two month old question. 😆
