Hey, not sure where to ask this but its a pretty general questio so: Are TextRenders really expensive? Is there a more efficient way to show text in world? I'm considering putting the text into my Textures and mapping them onto my surfaces, but that means I can't change them super easily at runtime. Thoughts?

Two things I'm wondering about. Firstly I'm finally moving on to making the foliage for my scene, that said since I'm doing a Breath of the Wild study I've noticed interesting things. One thing they do is mixing in little flowers into the grass, however it's only up close that you see them and they are only the blooms, there's no stalk. Seeing as how costly transparency is, is there another way to make a model like this? It's literally just flower blooms mixed in with the grass, swaying in the wind the same way, but no flower stalk. Given that it's only rendered at a closer look I could see Nintendo using transparency, but wanted to know of there were other opinions.
Secondly, I'm likely to need culling, I'm curious if there's a way to change how things are culled, either an actual fade out rather than the strange pixelated thing Unreal does, or have things render under the landscape and "grow" up from underground when coming into view, or the opposite when going out of view. And honestly I'd like the same for the LOD's. I'd assume this is something more for the coding side or maybe something the blueprint system could do? But this far I've only found a couple of posts of people making Unreal do this, but with no actual explanation on how. (Apologises for the text wall)

I would hazard to guess that Space Rangers (circa '03) would reduce its level of simulation of offscreen AI to something like a board game that updates every X seconds, and only simulates the local system in full fidelity, and has a way to translate the "board game" to a sensible full sim (and vice versa) when you jump across star systems. (Disclaimer: my experience as an actual game dev is nonexistent.)
As an aside... I actually played a fair bit of Space Rangers II back in its day. It stoked my nostalgia for Star Control 2 and I remember it having some pretty weird quests...

After merging in 4.23, we get this error message which I can't figure out where it comes from
"Command line error D8049: cannot execute 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Community2\VC\Tools\MSVC\14.16.27023\bin\HostX64\x64\c1xx.dll': command line is too long to fit in debug record".
Has anyone ever seen that or knows where to peek to figure that out?
vague plume
For having a bunch of out of system ai I’d probably set up something to update all the out of level ai at once every so often (as it’s not noticeable if you only update it once every 10 seconds or so) and only use basic data from them and otherwise just save them down (if day you have them as unique ships with unique interiors ect), such as just have ship name, location, destination, travel speed. So if you were to imagine a bunch of dots on a graph and every 10 seconds or so update their location until the reach their destination, then create the ship if it enters the players area execute another event somewhere else to pull up a bit more data to see what the ship should do next.
Something like renzu said. It just simplifies the offscreen stuff and doesn’t update it very often. If it’s an absurd amount of stuff you could probably even set up a nested array and then update one of the nested arrays of object every second, keeping the number of updates low to avoid spikes but consistent.

So I'm trying to make a flower bloom without it's stem and without using transparency to hide said stem, it's just something extra to scatter around the environment in the grass and such. That being said I just have the simple grass wind setup for testing, but it's not making the flower sway, it's just kind of jiggling around. Is that because of the simpleness of the node or perhaps the model itself?

I can remove just fine but when I add them back I want to add them back in the same order. Which doesn't seem to work
scarlet birch
I don't think there's a built in insert. Instead of removing, use a placeholder of somekind and set that index of the array to it. If you remove an index and want to put a new value in at the same index you'll have to setup your own insert/sort.
stiff spoke
I did what I wanted to do but I used another method but the problem is that the actor is in the animation or he to the weapon and ready to shoot the camera does not do that rotation by report to the character

I tried looping over the entire thing. Storing each element in a storage array. Deleting the axis mapping. Then recreating it exactly the same but with the change. It still won't let me FML

What are you trying to do? @thin tendon

Custom Keybinds for the players. I have the action mappings working. I'm now trying to get axis mappings working. But only setting the index I want

As you can see from the screenshot the bones are like that, in the animation and also everywhere with the models but in blender the bones are placed correctly. So thats make a huge transformation to the goblin. He now looks like an alien. Anyone know how to fix that ?
tardy grove
@scenic robin you need to lookup hhow to convert from blender to ue4
scenic robin
@tardy grove Thanks you was right. I just found what I needed.

Has anyone had an instant random shutdown of their PC when using Unreal? I was sorting my animation graphs and my PC just instantly lost went off

OK, so I have loaded into Unreal after the crash and it has deleted my Animation BP
I have spent so long doing it

Did you save periodically?

I've been trying to add a second layer of foliage to my landscape grass output, and it crashes every time i select the grass type to assign to the second layer. does anyone know if there is a work around or if im doing something wrong?
faint juniper
I clicked save manually like every few minutes and had auto save on
dim plover
Hmm, maybe autosave saved a backup. Also, I've heard people crash from/get screwed by autosave.
I personally have it turned off.

How much does line tracing affect the engine? I was planning on trying to use Tick to draw a line every tick but Im unsure if thats a foolish idea.
faint juniper
I NEED a way to recover that.....if not I may aswell pack in the whole Game Dev thing, cause that is ridiculous.....I was testing a State Machine, possibly had conflicting Logic, and its crashed my system and deleted all my hours of work.....why continue if its just going to do that at random in the future?
Any ideas?
Is there a recover back up, or view backed up versions?
grim ore
check your saved and autosaves folder
and check to see if the file is actually in the folder or not in your file system
@plush yew Line Traces are a normal part of any game engine and are very light weight to do the actual trace. It's not uncommon to do multiple if not hundreds of them a frame if needed based on your settings.
drawing a trace from the player to see what is in front of them every frame is nothing out of the ordinary for example, let alone even one at each appendage for something like climbing
plush yew
So it shouldnt cause any issues if I do? (plan to use around 8 to determine whats around the player)
faint juniper
@grim ore The Animation BP .uasset appears to be in the Folder when using Windows Explorer to navigate to my Game folders....however it does not show in Unreal
plush yew
Working on a wind protection and temperature system
faint juniper
@grim ore also it has unlinked from anything tied to it in Unreal (character animations not working, Tposes etc etc)
grim ore
@faint juniper then when you open the project check the output log, it might be showing up as corrupted. If that is the case your Saved/Autosaves might have another working copy.
@plush yew there is no way of knowing if it will be an issue with your setup, you have to try it and profile. Line traces by design are not heavy and using multiples of them every frame is not uncommon
faint juniper
@grim ore How do I recover a previous autosave?
grim ore
Your Saved/Autosaves might have another working copy.
plush yew
Alright then Ill attempt it :)
faint juniper
@grim ore , Thank you,it looks like there is....im hoping nothing else has went missing too. Although, the "saved" version I found is far older than what it should be- I have lost a few hours of work now. I have autosave to like every 10 minutes and I click compile and save pretty much every change I make.....so constantly. How do I prevent losing work like that in future? Any ideas?
grim ore
Use source control to commit after major changes, find out the problem that cause the issue in the first place and fix it, use something like dropbox to be really annoying and have it auto save for you with rollbacks, stop working every so often and make a full copy of the project somewhere else in the event this happen, don't worry about it and hope it never happens again.
faint juniper
@grim ore I honestly have no idea, the only thing I can think of is that the logic in my Anim state machine , I edited the State machine flow, went to test it, and as soon is i tried to enter in to the animation my PC cut out
Thanks for your help and suggestions !
sage tree
Where is a good place to learn where I should be putting my gameplay logic? Best practices are what I am looking for, working on a coop game, I know I can put things in the character controller, and I know a lot do that, but not sure its the best place.
grim ore
theres isnt much chance that UE4 crashing will kill your PC itself. IF you PC lost complete power thats a hardware issue there.
just bad timing
@sage tree there is no best practices for your game beyond what you decide is best for your game.
next badger
@grim ore i had an issue once when ue4 killed my gpu driver, so my screen went black...
grim ore
if it's networked there are things that just don't work locally VS server, you can check the networking compendium for that info. If you want to take advantage of systems that are in the engine then you should of course do that.
@next badger but did your PC shut down?
grim ore
I could possibly see UE4 pulling more power than your PSU can supply at peak load but again that's a hardware thing 😦
next badger
in cases when it can't provide enough power

Overheating can cause it too. Bad cooling can become apparent when you're hitting the chips hard compiling stuff.

there is an animation starter pack that you can download that does

If you're getting an Error 500 message, right click on the launcher icon in the taskbar's notification area and click Unreal Engine, it should take you to the Unreal Engine section of the launcher. At least that's what worked for me. The library subsection seems to be intact so you can access your projects.

Hi everyone,
I wanted to migrate the vehicle advanced blueprint to a blank project to practice, but after making a gamemode blueprint, setting the vehicle blueprint as the default pawn and adding the input axis this is what i get:
https://imgur.com/wpY9ug8
Noone of the cars move and I don't know what to do. Seems like a vehicle is being generated wherever my camera is right before clicking "Play"
grim ore
you can always add the vehicle template feature pack instead of migrating, that would bring over the car itself
and if your game mode is set to spawn in a vehicle it would do that
and you said it is set to spawn in a vehicle soo.....
hasty osprey
say i want to flipbook this texture so it gets a spinning animation how would i do that?
viral sluice
What I don't understand is why doesn't the vehicle move. It stays in the air, it doesn't move forward and wheels won't rotate
next badger
@hasty osprey why not to use rotator?
dawn gull
@next badger So, how do I fix it? Because it would take a long time to transfer it over to regular again I think
next badger
no clue, it's a custom build
dawn gull
rip it was the latest i could find
next badger
you may ask #legacy-physics #engine-source #cpp
next badger
if you're not using custom code - just copy, then right click .uproject and change version
dawn gull
ok
next badger
@hasty osprey btw, your texture using not whole space, it's wise to use all of the UV space to not waste texture resolution
dawn gull
What would happen if I didnt copy it?
next badger
@dawn gull you may break it...just in case
dawn gull
Ok

thanks i can try that too

If I copy it but dont paste it yet will that also work?

plush yew
do you think it would be easier to model the windows and create the glass material for it or create the whole glass material window in substance designer
next badger
@plush yew it depends on functionality
- will it be transparent
- will it be breakable
- how large will be glass to frame ratio
If it will be transparent it's better to make glass as separate mesh, apply a simple material to it with translucency
translucent materials are expensive, and do not write to depth buffer
*with exception of custom depth

@faint juniper using t.maxfps XXX sets the max fps in the editor, you do this thru the console (`) key

So Unity is heading for the scalable task -> worker implementation. How does UE4 scale when it comes to multi-threading? Is this something that can be answered for someone who uses BP only?
grim ore
certain things are multi threaded, they try and put certain parts of the engine on it's own if it can like animation or ui or game thread etc. (the docs have more info on what is what). As for BP it's not multithreaded unless the node is designed to work like that in the background (most are not going to be, they might be latent like AI moving frame by frame at the best) but there are plugins that can try and help with that adding in threading support. Anyone with skill can expose threading to BP if needed for specific tasks
frank escarp
@dim oriole it scales like absolute ass
faint juniper
@grim ore Thanks again!
frank escarp
if you take unreal 23 and check the Insights profiler, which shows a very nice Thread view, you will see it inmediately
next badger
afaik only way to launch a new thread in BP is to add delay 0
frank escarp
unreal engine has 2 mayor threads
a game thread (runs all blueprints/gamecode), and a render thread (runs rendering)
thats it
next badger
mayo-thread
frank escarp
the rest is just "helper stuff", but they just help in some small parts, like physics or animation
next badger
also audio runs in a separate thread afaik
plush yew
yes it will be transparent but i want it to have that bump offset so it has a fake look on the outside
frank escarp
@next badger yes but thats a very small cpu cost generally
you can get bottlenecked on game thread in unreal extremelly fast in consoles
because all the AActor based code + BPs is singlethread
in the PS4 if you add like 10 ShooterGame bots, you start losing the 60 fps
plush yew
i mean ive already started doing it in substance anyways without making a model so it doesnt really matter now
frank escarp
multithreading game code is also not possible to do. Anything that touches uobjects/actors is unsafe
dim oriole
And what about the future? Is this something that Epic will look into, or not a priority?
What if I have multiple particle effects/alembic animations playing. Can UE4 distribute across 8c/16t CPU, or I will be bottlenecked?
frank escarp
particle effects are singlethreaded (yuck!!!) and alembic too
fierce tulip
same for niagara?
frank escarp
animations are parallelized (the normal skeletal animations)
i dont know @fierce tulip
i know that cascade particle FX are singlelthread
all the effects of a frame will "calculate" at the start
fierce tulip
you'd think with the amount of core/thread increases these last few years there'd be more than 2 threads.
aside some small things
frank escarp
parallelizing is hard
the entire AActor model just does not work with MT
nor it will ever work
thats why unity is going with the ECS stuff. In the ECS model, making things parallel is not just doable, its trivial
so trivial it can be almost automatic
fierce tulip
well, never expected they'd be adding virtual texturing, who knows what we'll see in a few years.
different beast, sure
frank escarp
yeah who knows
but for example, take the rendering
unreal engine rendering is single thread + helpers for some parts
the issue is the huge bottleneck on the single-thread
AAA console engines, like Destiny engine and Uncharted 4 engine, work on a "task based" model
where they create tons of tasks in the code, and their dependencies, and then a central system spreads the tasks over all the cores
next badger
5 is a good number
frank escarp
for example, on rendering. There are several tasks that have to be done
You have to check what objects are in view.
You have to grab the meshes/materials for those, and prepare their rendering.
you also do view check for lights,
you calculate terrain LODs
you calculate particles
etc
in task based model, each of those things are a task, and will get executed in multiple cores
current unreal executes all of those in-order in a single thread, and for some parts (preparing mesh rendering) it uses multiple cores for a bit and then goes back to single-thread
dim oriole
Sounds like something Epic should be concerned about going into the future?
PS5 8c/16t? One year until both Xbox and PS launches.
frank escarp
they have already improved it a LOT for 4.22
on the rendering side
the game side is still 100% single-thread
personally i think unreal work on a few critical tasks to be more thread-safe. For example spawning objects from multiple threads, or moving objects from multiple threads
even if it works like async-traces, which just do a parallel-for at the end of the frame, would still be a huge win
cloud cobalt
UE4's gamble is that they can offer MT performance through implementing the biggest systems that might need it
And that developers who need actual threaded game logic will know how to do it themselves
frank escarp
yup
there are already ways of doing parallel-ticks
if unreal creates some sort of "thread safe command buffer" or similar, then a lot of people will just use parallel-ticks, even if its a super-advanced feature
hell, another possibility is to create more tick groups
frank escarp
for example, a PreParallel tick group
on that tick group, everything in the scene is read-only
cloud cobalt
We already have that with anim graph BP
frank escarp
so you use that tick group, and CAN do sweeps, rays/etc, but its all read only
you cant do actor set transform or similar
need to use the command buffer to enqueue it to execute after the tick group
something like that would inmediately parallelize easily 80% of the Character Movement logic
next badger
same as before?
magic epoch
It is missing alot of blueprints

Hello I am trying to import a modelled rigged character to unreal from blender and if i import the mesh without the rig the shading works fine but if i import it with the skeleton the shading breaks, anyone know how i can resolve this issue?
plush yew
well the shading works if i import it to marmoset with the rig but ue4 not having it
grim ore
if they are from the UE4 store then you should be able to remap them to the UE4 skeleton if ytou need it for some reason, but why not use the supplied skeleton?

@ember notch it may be the language barrier, but your questions barely look like questions, and are lacking in information to the point where nobody would be able to help you.

Honestly I don't know why they default to generate for SK normals. I get that animation can mess up the normals, but most of the time I think people would rather import them.

was working on a massive lotus, but had to halt it :/
next badger
Yeah, luos, have you used animation and then baked the uvs with the script?
or used the guide from Wiki?
fierce tulip
yea, used that guide until it became second nature
well, mainly I use baking to texture. did use the bake to seperate uv's a few times though
waiting for the question :p
next badger
watching the video =)))
fierce tulip
guess I did not show it in that vid, but I did bake it all down to vert anim hehe
next badger
yeah, seems like you're using morph...
the issue i have a predeformed mesh that i need to grow -_-
the wiki guide only relates on UV
fierce tulip
morph just made it easier hehe.
do you have a vid/gif of the growing?

no, the transition does not matters that much...the issue is that mesh already shaped -_-

Anyone have a sec to save me from an oft encountered headache? I have a third person template and I'm about to retarget the mannequin to my own skeletal mesh avatar. Thing is, I know once you do this it totally replaces the mannequin so all the animations work on my own custom avatar. This is great, but i'd like to somehow keep the mannequin and its animations intact. What do I need to duplicate to make this happen?
Is it enough to duplicate the mannequin skeleton and retarget to that? Will ask in animation also.
warped tangle
retarget the anim sequence/blendspaces? This will duplicate them (also if you retarget a blendspace, it will retarget the necessary anim sequnces for you automatically)
@gilded plinth
warped tangle
What I'm saying is don't retarget the skeleton, retarget the animations
yeah, if you retarget the blendspace, it will automatically duplicate and retarget the necessary assets
gilded plinth
Ok that makes sense, then I could just pop my new skeletal mesh into the third person bp along with the new blendspace and sequences where they need to go?
warped tangle
yep. You can also retarget an animBP and it should automatically duplicate and retarget everything it needs
gilded plinth
Basically I'd then duplicate the anim bp for my mesh so I can swap back and forth?
Should I just do the anim BP?
gilded plinth
Cool ya if that works i'd be all set. Might be a mess of duplicated files but oh well : ) There aren't actually that many anims that come with the mannequin third person anyhow
looks like 4-5 and then the blendspace, sequence etc
warped tangle
yeah, and if it doesn't automatically take you to the location where they duplicate to, it goes into the root folder
just FYI
gilded plinth
Cool. Retargeting is one of those things where there are 20 ways to get it wrong and 1 to get it right and it always takes a few tries : P

gilded plinth
@warped tangle when posing for re-targeting do you have any opinion whether it's better to pose the custom skeleton or the mannequin?
warped tangle
eh it's going to be personal preference
I tend to do A-pose to T-pose as A-pose can be harder to match elbows
gilded plinth
@warped tangle ya, my character is A-Pose so makes sense to keep it but the mannequin has those bent elbows and slightly bent fingers
seeing if i can put my avatar as close as possible without modifying the mannequin pose
warped tangle
modifying poses for retarget pose doesn't affect the base pose
nothing you do is permanent
gilded plinth
yup totally but i assume the closer the poses for the retarget the better the animation is gonna look
correct me if i'm wrong : )
warped tangle
yep

Hey all, Im super new to Unreal Engine and I've already hit a weird snag. I'm trying to control two players with one keyboard, and they aren't moving right at all lol
Is this the right place to ask for help? I can't seem to find another channel specifically for help.
Welp, I'm on a time crunch so I'll just ask away and mods can delete things if they must: Every time I move a player left or right (using new L/R Axis inputs), instead of going straight left or straight right, they move in a circular pattern.
Here's a quick clip of the problem.
What's weird is that when I use the default third person character (with the normal axis inputs), it moves perfectly fine. It's my axis inputs...or...something about this player that makes it weird.
Thanks in advance for the help!! Idk what I'm doing and google has failed me on this one thus far
sacred sun
@mild charm #blueprint is the channel to ask in. you're probably going to need to share pics of the input settings and blueprints. you could make a post on answer hub and link it, just so that your post isn't taking up a massive chuck of screenspace with pic and videos and responses ect.
mild charm
@sacred sun Unfortunately, I made this post super hastily and didn't spot the #blueprint channel in time lol. I've decided I'm gonna go through the basics of Blueprints just to get started, rather than mulling over this very strangely specific issue that I frankenstein'd from various "how to control two players at once" tutorials lol. Thanks for the help though! I'll be sure to post it there if I'm still majorly confused (which I probs will be)
sacred sun
@mild charm now that I think about it. you probably just have orient rotation to movement checked and then are using the characters right vector to turn, rather than the camera's right vector.

Every time I open the event graph to this BP it sticks me way far away from the nodes and its hard to scroll around and look for them cause its so far, how do I fix that?
sacred sun
make a random node where ever the bp opens to and move all the nodes to it. kinda wish the center of blueprint graphs were more clear, maybe there's some option in the editor settings I should look for someday. could also use the find/search. there's also bookmark system in blueprints too.

How does one program two working swords which utilize both hands. For example, as of now I have one sword working in one hand with animations, collisions, damage dealing, and is a child class from one master sword class.

Hiya! So I am going to be getting a pc to for developing and learning to develop games in the near future, (hopefully before February) and going through highschool I always wanted to make video games up til junior year where life hit me (won't go into detail) and then I contemplated what I wanted to do in my life ... What a waste of time that was ... Lol ... But anyway one of the things that helped me realize I still wanted to develop games was Dreams on ps4. I wasn't going to full on develop a game on there but more so use it to determine if I wanted too. And thus is how I got here, I made my decision. But that's not why I'm posting at the moment. I actually wanted to know about how logic/blueprint works in unreal 4. Because when I decided to look at some videos to learn a bit ahead of time (for which I never stuck around for, can't seem to find a good channel for that sort of thing) and I noticed that unreal 4 and dreams of this thing that looks similar, which I am going to assume is what the logic system is in unreal 4. So I wanted to know on a scale from 1-10 how similar these two systems are. 1 being not similar at all and 10 being a very similar or even the same maybe better then the other. I'm going to post 2 images for reference, thanks in advance for what you can tell me. Now I'm going to try to go to bed, it's about 2 30 am where I am. Lol
Oh and disclaimer, neither of these images are mine, just pulled them off of Google images

@hallow oracle It looks like the picture of the game you posted is similar in concept to a node-based logic system. However. UE4, while it also uses nodes for scripting (coding/scripting) in the Blueprint system, UE4 at it's core is a code based game engine like any other. So I wouldn't think of it as "logic system" as much as a visual programming system, which is what it is. Each node is a visual representation of C++ code. One of the things I often see with people new to development, is people tackling UE4 like it's a game, and trying to "solve" or "win" the game (we've gotten used to having hints guide us to objectives, etc, in games). This is not the case. Just know that up front, and enjoy your journey.
@plush yew Just off the top of my head, either predict projectile path or suggest projectile velocity has a "favor high arc" bool that will attempt to "lob" it high up and hit the target. This may be what you want to use.
plush yew
thanks @warped tangle I'm watching a MathewW video on predict projectile path rn!
plush yew
Yeah I was getting ready to write out the formulas myself but that seemed way too involved for somthing that seems pretty common
warped tangle
I would almost be willing to bet suggest projectile velocity is what you want. Give it the point you want to hit, favor high arc, and use the velocity to get your rotation
plush yew
Hmmm I might use that but I think I want a consistent projectile velocity so I'm looking for the arc right now

gdc uploaded a talk on ai projectiles to yt a couple days ago which could be helpful. seemed ridiculously complicated to me though i just skimmed it.
plush yew
oh wait, projectile velocity has an input for launch speed, does that mean that I can keep projectile speed consistent?
Yeah it's pretty involved. Because after I get the arcs down I'm going to have to make sure it works for targets at different z values, and then I'm going to try to get prediction down on top of that
warped tangle
What it's going to give you is the velocity needed at the given launch speed, start, and end points
that velocity can give you the rotation you need to feed to the archers
Really you aren't going to be USING the "toss velocity" output, but using that to derive the rotation you need
plush yew
I see, it isn't immediately clear to me where I'll be applying that rotation though. do I take that rotation and apply it to the projectile?
warped tangle
Well if you want your archers to rotate up, so it looks natural (rather than arrows firing up when they're aiming straight), you could do a dot product to figure out the angle
maybe rotation from x vector? I'd have to try it
spitballing here
honest vale
why not use toss velocity?
warped tangle
Again, if you use toss velocity, the arrows may fire up at ridiculous angles while the archers are aiming straight
my assumption is you're wanting to have them aim up and fire, more naturally
or you could use toss velocity directly on the arrow projectile
plush yew
yeah that's what I'm aiming for right now
warped tangle
I think that will give you the output you need regardless
may have to run it twice, once for the archer body rotation, then once at the end of the body movement to get the new velocit
velocity*
Just depends how realistic you want it to look (if they're at distance and you won't even see them really, then you can fake it quite a bit)
plush yew
Yeah I'll be considering a lot of that when LOD comes into the picture
hmn, the arrows are just dropping to the ground now. I can probabyl figure this out on my own though. I thought I'd just take the toss velocity and plug it straight into the projectile velocity then activate the projectile but that didn't seem to be it

honest vale
you might want to lower lightmap resolutions if that's the case 😛
plush yew
How can I decrease the quality? >_<

Make sure you're not doing anything dumb, like statically-lit trees or vegetation
plush yew
Toss velocity is returning 0,0,0 even though the predicted paths are accurate
I had it set to 'trace full path' so nevermind that didn't do what I thought it did and was causing problems as a result
warped tangle
so it's working?

I have a problem on my game that happens several times the problem is that sometimes when I turn off my computer certain Blueprint this even removes levels why and is there a way to recover them and in addition when from my computer I go into the file where are these blueprint or these level that disappear I see them but in the ue4 nothing

Do you guys think Unreal is good for a 2D or 2.5D game?
stiff spoke
No solution for my problem?
plush yew
to cover edges of some platforms, exactly like in the picture
Anybody knows where I can find this ?
warped tangle
@stiff spoke Your problem sounds like an issue with your computer
dark depot
that or not saving
warped tangle
^
stiff spoke
OK so?
wary wave
it's not an Unreal issue, it literally sounds like you're not saving files?
why they would not be saved, I couldn't say
stiff spoke
If I'm doing save all

Basically it's a problem on your end with your computer

Anyone know why I crash the editor if I don't disable my onboard graphics card? I have an intel 630 and 2070 maxQ in my laptop and I crash regularly if I have both active even though it's set to only use the Nvidia card. Disabling it prevents the crashes, but things seem to run a bit chunky. Not sure what the other card is doing in the background
royal osprey
could anyone help me with character selection screen and so that when i pick that character it still saves all progress?
its a 2D character selection
copper flicker
so save the game upon picking the character..
@royal osprey I think you can call a save game anytime you need.. why not from you character sel
royal osprey
how would i go about doing this ive got an idea in my head but not to sure
cause what i wanna do is select that character than they go back the start the level
sinful osprey
@royal osprey Check this out for some help on save games. It's fairly old, but I think it's still accurate for the most part. Keep in mind that GameInstance is persistent through levels so it's a good place to store data you want to move from a menu to a level for save/load. https://answers.unrealengine.com/questions/84785/tappy-chicken-score-system-for-multiple-maps.html?childToView=85031#answer-85031

Hey guys, hello everyone, I need your advice, I still struggle with snapping in UE 4 4.23
- I do everything like in manual doc and tutorials, I set pivot point to vertex I want and setting - set pivot offset, it remembers it, but If I move my asset it just reset it after any movement, I have to select this object once again and miracly its pivot point back again were I saved it earlier.
- In Maya I am setting pivot point on center - freeze transform, but when I import object in UE 4, the pivot point is just miles away, strange but I have no this problem importing in Unity, something to check in Import setting? I tried to look on option during mesh import, nothing specific.
3.When I am changing position of my pivot point in UE 4 with V + MMB, it highlights vertices for a sec and would to any vertices on any other asset object except on original, it take me time and struggle to set pivot point right and as closer as I can to vertex I want to snap by ALT + MMB.
It is so time consuming, I need help on this, I just waste a lot of time fighting with these pivots, more then on level building itself. Plz help

@stone finch send me your maya file

warped tangle
Whats the issue pierr
night basalt
thx 🙂
stone finch
update with issue 2, file contains world space info, and UE 4 use not Object Transform Attributes, but World Space params, any way to
@copper flicker give me a sec
copper flicker
just work cleanly.... set things at 0 0 0 in maya
I think it may be the FBX exporter that ignores your maya offset
meanwhile.. I have a surreal bug.
probably my logic tho... so I dunno how to explain it O o
my AIs move from Move State to Move State...... on Move To Location or Actor Fail or Move Finish.
thing is.... sometimes they move to another move state... while not finishing or failing
😄
stone finch
@copper flicker The thing is after using Freeze transformation, all bake softwares read mesh position as 0 0 0, Unity also reads pivot and object position from mesh param that were freeze transformed. And UE 4 using world space params, there must be a way in import options maybe where you can choose between world space and object space info
copper flicker
is your pivot at 0 0 0 in Maya?..
I freeze transforms all the time, no problemo
set your Maya pivot to 0 0 0
I have a script for that..
before exporting, I set all my piv to 0
hasty osprey
quick question why isn't the mat offsetting?
warped tangle
did you set a time and speed?
hasty osprey
yeah, the preview node on multiply is moving
the panner is just using it's default values, and the panning works when i preview the multiply
hasty osprey
oh ok, so i need to multiply it before multiplying it with the vertex normal then
plush yew
anywhere after ur texture

thanks👌

so, how would I go about adding a keyboard shortcut for the material instance "show or hide all material parameters" button? its not exposed in preferences, and not sure what to add to the ini to get it going.

Hey Guys , I am using a Data Table to hold some assets for number of characters , So when I spawn the character from the list is it going to load all the characters assets .
How can i keep the reference of any asset and just the load the asset when needed .
stone finch
@copper flicker I made test 1 and test 3 examples, in Test 3 object is moved in scene, but its tranformations as an pivot are freeze transformed in Test 1 I just reset transformation on object, the thing is it does matter if i modify Pivot point in Maya itself, UE4 will just reset it to World Space values that were in scene with FBX
Test1
Test 1 in engine
Test 3, look at object params and world space values
Test 3 in Engine
Pivot point that was centered in Maya and freeze transformed was reset in UE 4
But the worst part for me if you want to move - snap this pivot point before Pivot -> Set as Pivot offset in UE 4, ill show it up, it will snap to any verticies except on its original needed object

@rustic magnet - for a skateboard type vehicle + terrain, the sphere is a pretty nice approximation
it is not the way most people would do a wheeled vehicle, however

Hey all,
Can someone please help with the FaceARSample setup, in relation to importing a .mobileprovision file?

Guys, really what I am doing wrong with snapping, it just dont want to snap to its own mesh verticies
