does anyone else experience random crashes while editing blueprints or anything else?

viscid glen Sep 29, 2019, 11:05 PM

#

Trying to show one of theses sprites. Any idea how to do this?

#

@viscid glen you usually get 3 from clamp node. Random integer node returns some number between 0 and some high max value, which is more often than not equal or larger than 3. When clamp gets n >= 3 it outputs 3. If you want numbers that are more or less evenly spread between 0, 1, and 2 use mod 3 node

#

Other than that you should place select node on the other side of set Sprite node. It's output should be connected to set Sprite input.

short drift Sep 29, 2019, 11:27 PM

#

Hi guys i am pretty new to unreal, any idea how i can get this node?

viscid glen Sep 29, 2019, 11:31 PM

#

@burnt sparrow Like this?

📎 unknown.png

burnt sparrow Sep 29, 2019, 11:35 PM

#

Delete clamp, comparison and bool to int conversion nodes. Inserted of them use modulo node on output from random node. Should be visible when you search for '%' or 'mod' after pulling from random.

#

And you only need one set sprite node.

viscid glen Sep 29, 2019, 11:37 PM

#

what should i set the bottom of the modulo node to be?

burnt sparrow Sep 29, 2019, 11:38 PM

#

3

#

It returns reminder of division by the bottom number

#

Reminder of division by 3 is always 0, 1 or 2

viscid glen Sep 29, 2019, 11:40 PM

#

Ahh It works I think but all mob have the same text is there a way of giving each individual one a different text?

burnt sparrow Sep 29, 2019, 11:41 PM

#

You mean the same sprite? Are you sure you've connected the exec pin on set sprite?

short drift Sep 29, 2019, 11:42 PM

#

Hi i know the node is a material output but i don't know how to open all the attribute

viscid glen Sep 29, 2019, 11:44 PM

#

It gives the same sprite for all of the mobs

📎 unknown.png

burnt sparrow Sep 29, 2019, 11:49 PM

#

That's strange, looks fine to me. Add print string node before setting the sprite and see what random node returns.

viscid glen Sep 29, 2019, 11:51 PM

Ive set it to be changed every 1 second

@burnt sparrow Thanks I didnt set a max for the random 😛 my bad thanks for your help

burnt sparrow Sep 29, 2019, 11:54 PM

#

Oh yeah, I forgot about the input on that node

#

Somehow I assumed it's some static value and didn't even notice it was on the screen

#

Now you don't even need modulo node, just set max to 3

plush yew Sep 30, 2019, 12:02 AM

#

There is many layers to use. I suppose we must take the "m_vertex_paint" (the first in the list i my screenshot, to the right) but I'm a bit lost when I'm use it...

I manage to switch between the layers here (see the buttons where I click) :

@short drift you just need to enable or disable options to get it to look like that. There is no reason to have all of them enabled if you don't need them. Do you need a specific input ?

grim ore Sep 30, 2019, 12:24 AM

sin is already part of the engine, tiling is based on the UV's so you can use a texture coord node for that

@stiff spoke there are Damage events built into actors in the engine, you can use those. You can implement a custom event to call. If you are not even at that point and need to test based on collision then you can use overlap or hit events. your question is too vague to give an answer.

stiff spoke Sep 30, 2019, 1:52 AM

Do you know that for example in a game at the end of a timer or time at the player who has the highest score wins and A widget is displayed as you win and in the rest you lose

The engine is networked out of the box so it depends on what a "simple-ish" game consists of

sudden agate Sep 30, 2019, 7:02 AM

You can't

#

Use a timer instead

astral marsh Sep 30, 2019, 7:19 AM

#

which timer

wary wave Sep 30, 2019, 7:25 AM

#

Timer

#

it is literally called Timer

plush yew Sep 30, 2019, 7:34 AM

Hey, I got a game where the player is a cube and you can move it in the x axis, Now, In my computer, The player is moving perfectly fine, But when i tested it on a different computer, The player was very slow. I don't know if it helps but the different computer that i tested it on is pretty weak

wary wave Sep 30, 2019, 7:35 AM

#

you are probably not using DeltaTime in your movement calculations, which means they are entirely subject to frame rate

plush yew Sep 30, 2019, 7:37 AM

#

Oh ok, Is there a thing called FixedDeltaTime? I've been using unity for like a year and a half now, so i'm just guessing

#

Cuz Unity has a thing called DeltaTime and FixedDeltaTime

sudden agate Sep 30, 2019, 7:38 AM

#

There is Delta Time in Event Tick

#

and also a Get World Delta Seconds as a static function

plush yew Sep 30, 2019, 7:38 AM

#

This is how i move the player

📎 unknown.png

sudden agate Sep 30, 2019, 7:39 AM

#

AddImpulse is a Physics function, you should move the Pawn with a Movement Component

mossy nymph Sep 30, 2019, 7:39 AM

#

most people do AddMovementInput

#

which adjusts for the DeltaTime on its own

plush yew Sep 30, 2019, 7:39 AM

#

So do i just change "add impulse"?

#

This is from a tutorial btw

#

Just saying

sudden agate Sep 30, 2019, 7:40 AM

#

this tutorial sucks

plush yew Sep 30, 2019, 7:40 AM

#

Yup

#

So like this?

📎 unknown.png

#

Nvm, The player is now not moving

sudden agate Sep 30, 2019, 7:41 AM

#

World Direction would be X only

#

Speed*Axisvalue would be your Scale Value

#

i.e. World Direction would be a vector 1,0,0

#

AxisValue goes negative if you push it into the opposite direction when set up correctly in the input settings

#

so you would go to -1,0,0 when you push it into the opposite direction

astral marsh Sep 30, 2019, 7:42 AM

#

i see no timer node

#

except the set ones

wary wave Sep 30, 2019, 7:42 AM

#

whatever tutorial you're following seems pretty poor, because not accounting for delta time is madness

sudden agate Sep 30, 2019, 7:42 AM

Set Timer

plush yew Sep 30, 2019, 7:42 AM

@plush yew I would recommend creating a project with the third person template and looking through how that works

sudden agate Sep 30, 2019, 7:45 AM

as @sudden agate asked, does it have a movement component

#

How do i check if it has a movement component?

#

sorry for stupid question

warped tangle Sep 30, 2019, 7:48 AM

#

I believe it's called a floating pawn movement component

#

It would be on the left, where it says like default scene root, etc

sudden agate Sep 30, 2019, 7:48 AM

#

Wait so if not get all actors with tag, How do you do it?

sudden agate Sep 30, 2019, 7:54 AM

#

@plush yew Use the function "MoveUpdatedComponent" from the movement component

plush yew Sep 30, 2019, 7:54 AM

#

Ok, One second

sudden agate Sep 30, 2019, 7:54 AM

#

you register the actors manually

wary wave Sep 30, 2019, 7:55 AM

#

depends what you're trying to do, but if it's a collision, you test the class of the actor you hit

warped tangle Sep 30, 2019, 7:55 AM

#

^

wary wave Sep 30, 2019, 7:55 AM

#

and yes, you would usually have a manager class that keeps track of your blocks

#

GetAllActorsByTag in gameplay code is a sin

#

it's one of the most expensive single nodes you can use

sudden agate Sep 30, 2019, 7:55 AM

#

use it on beginplay if you really need to

#

but nowhere else

honest vale Sep 30, 2019, 7:56 AM

#

does it iterate through all actors?

wary wave Sep 30, 2019, 7:56 AM

#

yeah, it will iterate through every actor and do string comparisons on the tags

warped tangle Sep 30, 2019, 7:56 AM

#

Yeah it's worse than getallactorsofclass

honest vale Sep 30, 2019, 7:56 AM

#

you'd imagine the engine kept references to the actors in bins based on tags

#

and then juts returns the bin contents

sudden agate Sep 30, 2019, 7:56 AM

#

epic doesnt think that far

honest vale Sep 30, 2019, 7:56 AM

#

but I guess not 😄

warped tangle Sep 30, 2019, 7:57 AM

#

No, you just keep your references or test on hits or some other method lol

wary wave Sep 30, 2019, 7:57 AM

#

I don't believe it does, largely because I don't think the tag system is ever really meant to be used like that

MoveUpdatedComponent is giving me an error, I need to connect something to the target, But when i try to connect the paddle, It gives me an error.....

warped tangle Sep 30, 2019, 8:14 AM

#

I have no idea what you're talking about lol

plush yew Sep 30, 2019, 8:14 AM

#

Oh I guess you didn't see my problem

#

So what happened is when I test it on my computer everything works fine but when I go to a slower computer the pawn moves very very very slow

warped tangle Sep 30, 2019, 8:15 AM

#

sounds like a framerate issue

plush yew Sep 30, 2019, 8:15 AM

#

Yeah

warped tangle Sep 30, 2019, 8:16 AM

#

if you haven't already, go to editor preferences -> search show framerate -> check the box for "show frame rate and memory"

plush yew Sep 30, 2019, 8:16 AM

#

Ambershee said that i need to use deltatime

warped tangle Sep 30, 2019, 8:16 AM

#

it will show your framerate in the top right of the editor

#

Using deltatime will generally speaking make things framerate independent

plush yew Sep 30, 2019, 8:17 AM

#

I get 120 fps

#

Is there any way to fix my problem?

warped tangle Sep 30, 2019, 8:18 AM

#

what's wrong with 120 fps?

plush yew Sep 30, 2019, 8:18 AM

#

No, Again, When i go to a slower computer with the built game, The pawn barely moves

warped tangle Sep 30, 2019, 8:18 AM

#

....don't play it on a computer that slow? Performance profile it? I dunno what state your game is in

#

I'm assuming there's nothing to it as you're working on pawn movement right now

serene birch Sep 30, 2019, 8:19 AM

#

it looks like you move the actors by a fixed amount per frame

#

it is weird though

plush yew Sep 30, 2019, 8:20 AM

#

So I can't fix it, that's what you're saying?

#

I already had the pawn movement

serene birch Sep 30, 2019, 8:20 AM

#

no it should basically work

warped tangle Sep 30, 2019, 8:20 AM

#

"fix it" is a super subjective thing, sure you can fix it

#

but if that's your target hardware or something, you need to get to the root of why you're getting that kind of performance

regal mulch Sep 30, 2019, 8:21 AM

#

MovementInput should handle DeltaSeconds already.

#

At least for Characters.

warped tangle Sep 30, 2019, 8:21 AM

#

yeah not sure for pawn

plush yew Sep 30, 2019, 8:21 AM

#

Oh

regal mulch Sep 30, 2019, 8:21 AM

#

If you would apply this on Tick by hand, then you'd need to use DeltaSeconds.

warped tangle Sep 30, 2019, 8:21 AM

#

I would imagine it handles it for pawn as well

plush yew Sep 30, 2019, 8:21 AM

#

Ok so I will go test it again

regal mulch Sep 30, 2019, 8:21 AM

#

Is that pawn using a MovementComponent?

warped tangle Sep 30, 2019, 8:21 AM

#

floating pawn movement

plush yew Sep 30, 2019, 8:21 AM

#

Yes, floatingpawnmovement

serene birch Sep 30, 2019, 8:22 AM

#

ah the BP above isn't your code!

plush yew Sep 30, 2019, 8:22 AM

This is what i got

serene birch Sep 30, 2019, 8:22 AM

#

the most recent screenshot 😮

regal mulch Sep 30, 2019, 8:23 AM

#

FloatPawnMovement does utilize the DeltaSeconds internally

#

So yes, it's not needed to use them (or actually not even suggested) when using AddMovementInput

plush yew Sep 30, 2019, 8:23 AM

#

Alright, Thank you all!

#

Well now that i turned off simulate physics, The player can just get out of the map, because he doesn't have collision with the bounds, How can i fix that?

leaden mauve Sep 30, 2019, 8:39 AM

#

add blocking volumes, if you need one big box they can move in, you can use Hollow-setting on the volume

plush yew Sep 30, 2019, 8:42 AM

#

I added the block volume, But my pawn still can move through it....

sudden agate Sep 30, 2019, 8:52 AM

#

make sure the collision presets match

#

if your pawn is in the pawn channel, the blocking volume needs to block pawn

#

etc

A working 4.22 template of mine now crashes on start at 4.23

From what I gathered it's two edgraph pins that are corrupted. 😦

But the thing is, I don't know which pins they are.. I got no AI system either and my game does not even need to build lightmaps or something.

I tried it in a new Map too (and my map was almost empty too)

Owh, can you please elobarate on what a recursion is? I am a blueprinter only so ^^'

oh nwm, checking the net for it

so could this mean a pin A is requesting data from pin B that asked about pin A before?

ripe saffron Sep 30, 2019, 9:15 AM

@plush yew 120fps with slow movement sounds like you have fixed frame rate checked

Yeah, I fixed that, All i have to fix is the pawn being able to get out of the map

@lucid jetty - a more complete call stack may yield more info

sudden agate Sep 30, 2019, 9:18 AM

#

@lucid jetty recursion means a function calls itself

wary wave Sep 30, 2019, 9:18 AM

#

but a recursive error is a good bet, code going around in circles

lucid jetty Sep 30, 2019, 9:19 AM

#

Thank you for the responses everyone, the rest of the callstack is the same.

#

It's literally spamming what I showed up ^^

#

But how can this never happened before at other versions? I mean, if I was a C++ I could say "I coded bad".

#

But I am using blueprints only T-T

wary wave Sep 30, 2019, 9:20 AM

#

well, look to the beginning of the call stack, it may not all be the same

#

you may be able to see the root function

lucid jetty Sep 30, 2019, 9:20 AM

#

I see. Can you please elobarate on how to check the call stack? I apologise if I am persistent, I just don't know how these stuff work. ^_^'''

#

Maybe I am understanding "check call stack" wrong so ^^'

plush yew Sep 30, 2019, 9:24 AM

#

Blocking volume can block an actor without simulation of physics?

wary wave Sep 30, 2019, 9:25 AM

#

it's the list of functions the application went through to get to the current point; the top of the stack is the newest, the bottom the oldest - so the root cause of the problem is likely to be towards the bottom of that list if it is repeated several times

lucid jetty Sep 30, 2019, 9:25 AM

#

Got it! But um, where do I check it? o:

wary wave Sep 30, 2019, 9:26 AM

#

you said it was "spamming" what you highlighted

#

it probably isn't

#

if it's a recursive problem, it has gone through the same functions multiple times

#

but the bottom of that stack should show the entry point

lucid jetty Sep 30, 2019, 9:27 AM

#

I see, I will do a deeper check, thanks for your time ^^

I need help peeps, I was trying to build the Spatial OS fork for UE4 and even though it says that I need to be sure to have 60GB of space, which I did, before installing the dependencies and prerequisites it still ran out of space

#

and now even after emptying like half of my SSD it's still running out of space and I'm getting this

📎 devenv_2019-09-30_12-48-02.png

#

the source folder has 60GB right now and I assume the leftover built files from the previous failed build are hanging around and killing my space

#

does anyone know which folders I could delete to restart the build from scratch?

#

(without deleting the dependencies or the source because my net is really bad and it would take me a day to download it again)

wary wave Sep 30, 2019, 12:01 PM

#

shouldn't really be any leftover files

#

you just plain need more disk space, 60GB is not a lot when working with a UE4 source build

tawdry python Sep 30, 2019, 12:01 PM

#

after downloading the dependencies the folder was at about 15GB

wary wave Sep 30, 2019, 12:02 PM

#

the project I'm working on here I have a 1TB drive, and I've had to clear that out from time to time

#

granted the assets take up a lot of that

tulip knot Sep 30, 2019, 12:02 PM

#

@tawdry python don't use spaces in paths if you are using spatialos

tawdry python Sep 30, 2019, 12:03 PM

#

I have a 1.5TB drive aside but I want the build to be on my SSD and I sadly only have a 250GB SSD (and I only gave windows 170GB, the rest being for my linux dual boot)

#

@tulip knot thanks for the tip I'll fix that

#

wait will it fail if I change the folder's name now?

#

I don't see why Spatial OS would say you only need 60GB for the whole process

#

when Visual Studio alone has eaten 20 GB

#

with all the SDKs and packages and whatnot

dim merlin Sep 30, 2019, 12:13 PM

#

is it cheaper to make a material instance when multiple (same) static meshes are in scene?

#

or is just a material used as instance in engine?

fierce tulip Sep 30, 2019, 12:14 PM

#

if they are the same, you can just apply the same material to them

dim merlin Sep 30, 2019, 12:15 PM

is it safe to delete User/AppData/Local/UnrealEngine?

fierce tulip Sep 30, 2019, 12:22 PM

#

id delete the files in that folder, not the unrealengine folder itself

#

keep in mind it will mean that all the shaders need recompiling

#

And if I am correctly it will also delete some usersettings

tawdry python Sep 30, 2019, 12:23 PM

#

yeah it's fine I have some leftover 4.21 and 4.20 shaders even though I don't use them anymore

fierce tulip Sep 30, 2019, 12:23 PM

tawdry python Sep 30, 2019, 12:23 PM

fierce tulip Sep 30, 2019, 12:23 PM

#

in that case, just remove those 🙂

tawdry python Sep 30, 2019, 12:24 PM

it seems like 4.22/Saved/Swarm is what's using the most

fierce tulip Sep 30, 2019, 12:25 PM

it depends a bit on what you do most in your project, but removing them is fine.

How do I do finer transform on UE4?

#

The buttons/numbers in the top left allow you change snapping distances. You can even turn off snapping.

tame delta Sep 30, 2019, 12:30 PM

#

Actually same question for any numerical input in the entire UI, often time I just want to drag the value a bit higher, but then factor it's increasing at is like 2 or 3 orders of magnitude higher than what I would expect

#

It's set to the minimum (1) and not snapping

#

Snapping is off in that video, you can see my cursor is just moving a few pixels

#

Someone on AH mentions that this number affects the finess, but it doesn't in my experience. https://i.imgur.com/2iSYc3S.png

Imgur

fierce tulip Sep 30, 2019, 12:34 PM

#

those numbers only work if grid snapping is enabled, else it should be rather smooth movage

tame delta Sep 30, 2019, 12:34 PM

#

Well as you can see it's way too sensitive

#

And this is all "to scale", I'm using this in a VR setting, so it's all reasonably sized

fierce tulip Sep 30, 2019, 12:35 PM

#

the way that moves does make it feel like snap is enabled somehow

sudden agate Sep 30, 2019, 12:36 PM

#

@tame delta You can change the snapping distances in the Editor Preferences

tame delta Sep 30, 2019, 12:36 PM

#

I guarantee you it's not, the snapping is literally just my mouse moving from pixel to pixel

#

And not that it would help, but my mouse is on very low DPI (for those instances exactly)

#

If you load up Unreal right now, can you place an object at mm precision?

fierce tulip Sep 30, 2019, 12:37 PM

#

i dont use non-snap for precision :p

tame delta Sep 30, 2019, 12:37 PM

#

This seems to move it a couple cms at a time, which is probably fine most of the time, but when you want to place something precisely I don't see a viable option

sudden agate Sep 30, 2019, 12:37 PM

#

change the snapping distances

#

to 0.01 i you want to have it mm perfect

fierce tulip Sep 30, 2019, 12:37 PM

#

if change the numbers in the transform tab

tame delta Sep 30, 2019, 12:37 PM

#

Well yeah, I suppose that's valid for level design, but this is all from CAD, they don't bother about staying on a global grid

fierce tulip Sep 30, 2019, 12:37 PM

#

but yea, rail's sugg is also good

tame delta Sep 30, 2019, 12:38 PM

@sudden agate Snapping distance even with snapping off?

with snapping on of course

what is the issue actually? lol

#

can i store data in a mesh?

tame delta Sep 30, 2019, 12:39 PM

#

@sudden agate The issue is that I need to move something precisely

#

Without entering numbers by hand about 20 times

tawdry python Sep 30, 2019, 12:39 PM

#

@tame delta maybe it has something to do with mouse sensitivity ?

sudden agate Sep 30, 2019, 12:39 PM

#

precisely
snapping turned off

tame delta Sep 30, 2019, 12:39 PM

Finely

#

Is a better word I suppose

sudden agate Sep 30, 2019, 12:40 PM

#

if i want to move something precisely, i turn on snapping

tame delta Sep 30, 2019, 12:40 PM

#

Right

#

I don't know if you don't understand my problem or don't want to understand it

#

I want to move something more "slowly"

#

Snapping is useless to me since that object can't be positioned on a nice round grid

#

Because it's CAD models, not level design stuff

plush yew Sep 30, 2019, 12:41 PM

#

snapping is very useful for CAD tbh lol

tame delta Sep 30, 2019, 12:42 PM

#

Alright, then perhaps I'll take that up to the dozens of engineers feeding me Steps, I'm sure they'll understand that the software I told them was the best for the job "couldn't reliably move things precisely enough"

#

Sorry if I'm being snarky but I'm looking for a solution is all, not trying to justifying endlessly why I want to do it.

plush yew Sep 30, 2019, 12:43 PM

#

im not saying you cannot not use snapping if you like it 🙂

#

you know about vertex snapping right?

#

might be useful for you

tame delta Sep 30, 2019, 12:44 PM

#

I tried using surface snapping but it wouldn't work

#

It snapped it to something way further, again looking like there's a big mismatch between what Unreal feels is a reasonably standard length and what I tend to work with

plush yew Sep 30, 2019, 12:45 PM

#

you can snap actual vertices together as well (hold V)

tame delta Sep 30, 2019, 12:45 PM

#

I don't need extreme precision, but I'd just want to do something like "Shift+Drag" in 3D modelling software to move something 10 times slower

#

or something like that

#

Or even just a global setting for "transform speed"

sudden agate Sep 30, 2019, 12:46 PM

#

well, your mouse determines the "transform speed"

#

alex

tame delta Sep 30, 2019, 12:46 PM

It doesn't

digital anchor Sep 30, 2019, 12:47 PM

the mesh is clearly moving faster than the mouse in that video

tame delta Sep 30, 2019, 12:47 PM

#

Not when I can't move my cursor to subpixel precision

#

Thanks Takain

#

It's moving way faster

plush yew Sep 30, 2019, 12:47 PM

you just cant disable snapping or something?

digital anchor Sep 30, 2019, 12:47 PM

the mesh isnt moving faster. your pivot is just very far away

plush yew Sep 30, 2019, 12:48 PM

#

in fact the mesh is moving slower... lol

tame delta Sep 30, 2019, 12:48 PM

#

Hmm depends

#

I can't really move any mesh precisely

plush yew Sep 30, 2019, 12:48 PM

either way its normal, i didnt see the video until now

#

move your camera close to the pivot point

tame delta Sep 30, 2019, 12:48 PM

#

The pivot is moving weirdly, but that's because I repositioned it

if the pivot point is inconveniant you can move it around with middle mouse button and ctrl iirc

plush yew Sep 30, 2019, 12:50 PM

#

but erm, vertex snapping looks very useful for you as i thought when i read CAD

tame delta Sep 30, 2019, 12:50 PM

#

This is as close as I can get to the mesh without clipping near

fierce tulip Sep 30, 2019, 12:50 PM

#

another tip could be to shift-click on an additional mesh, as the pivot of that last mesh will be used.
That at least could potentially help with dragging stuff with a pivot on a more helpful location.

#

Its how I sometimes rotate things more accurately when I have multiple things selected

plush yew Sep 30, 2019, 12:50 PM

#

lol thats a nice quick hack 🙂 i like it

#

if you plan on doing this stuff a lot its probably best to find a good way to position it correctly though

#

just eyeballing it is not going to make the engineers happy most likely

tame delta Sep 30, 2019, 12:51 PM

#

Well it's just for VR visualisation

digital anchor Sep 30, 2019, 12:52 PM

ah i see now, yeah moving with the pivot far away will cause that

tame delta Sep 30, 2019, 12:52 PM

#

I only need to import a couple of meshes because I had to rework there normals

#

Yeah I don't know why redefining a temporary pivot screws up transform

plush yew Sep 30, 2019, 12:52 PM

#

it doesnt

tame delta Sep 30, 2019, 12:52 PM

#

I guess it's still using the distance/screenspace depth of the original pivot

plush yew Sep 30, 2019, 12:53 PM

#

nope

#

do the same in blender

#

same will happen

fierce tulip Sep 30, 2019, 12:53 PM

#

another weirded idea is to put it all into a blueprint and set its location correctly

plush yew Sep 30, 2019, 12:53 PM

#

or use vertex snapping to snap the parts together, but i guess thats too simple :-p

fierce tulip Sep 30, 2019, 12:53 PM

not sure if there are any ramifications of doing that

tame delta Sep 30, 2019, 12:54 PM

sudden agate Sep 30, 2019, 12:55 PM

you can move them precisely there

hi, I'm having trouble getting an RTSP stream to play in UE, I hope this is the right channel to ask?
I followed the tutorial here: https://docs.unrealengine.com/en-US/Engine/MediaFramework/HowTo/StreamMediaSource/index.html and it works just fine with the sample video, but I'm trying to stream from a locally running RTSP server. I verified in VLC that the server is working fine, but in UE it only displays a black texture
The stream is h.264 encoded
anyone have an idea?

@tame delta whats looks screwy about that?

#

i assume that shadow is baked lighting and thats the only thing i see thats looking off

tame delta Sep 30, 2019, 1:03 PM

#

@plush yew The fact that the mesh moves much faster than the cursor

#

but I suppose it's just that UE refuses to place the gizmo on the mesh right in front

#

and instead put it behind it on another mesh

sudden agate Sep 30, 2019, 1:04 PM

well, your mesh is shit

your mesh is way off the center

your pivot is not at the center of the mesh

tame delta Sep 30, 2019, 1:05 PM

#

But then it's Datasmith's fault

plush yew Sep 30, 2019, 1:05 PM

#

no this is how 3d software works

sudden agate Sep 30, 2019, 1:05 PM

#

zoom into the pivot, and move it the way you want

plush yew Sep 30, 2019, 1:05 PM

#

its nothing weird

tame delta Sep 30, 2019, 1:05 PM

#

The only reason I have to place this by hand is because this specific mesh I had to reexport and edit

#

the rest is positioned nicely

plush yew Sep 30, 2019, 1:05 PM

#

yeah zoom in to it, or move it closer to where your cam is

#

its as simple as that

tame delta Sep 30, 2019, 1:05 PM

#

How do I move the pivot?

#

except by doing Shift+MMB

plush yew Sep 30, 2019, 1:06 PM

#

and i told you you can use vertex snapping to position is correctly

#

assuming there are vertices you can use but it looks like there are

#

you want to re-assign the key combination?

tame delta Sep 30, 2019, 1:06 PM

#

It casts it through the mesh

plush yew Sep 30, 2019, 1:07 PM

#

i mean it almost sounds like you want your own dev team to make your own engine that does everything for you

#

well yes your pivot point doesnt care about your mesh

tame delta Sep 30, 2019, 1:07 PM

#

I don't know what you're heating up about, I said I'm happy with the orthogonal view

plush yew Sep 30, 2019, 1:07 PM

#

its just hte point you use to move it and rotate it

tame delta Sep 30, 2019, 1:07 PM

#

Please remain courteous.

fierce tulip Sep 30, 2019, 1:07 PM

#

k, no need for being harsh. being frustrated is enough frustration as it is :p

plush yew Sep 30, 2019, 1:08 PM

#

what exactly was harsh?

fierce tulip Sep 30, 2019, 1:08 PM

#

maybe not the right word, but you know what I mean.

#

having said that, it was what? 20 meshes?

plush yew Sep 30, 2019, 1:08 PM

#

with vertex snapping it takes a matter of minutes

tame delta Sep 30, 2019, 1:09 PM

#

I don't know how many I have to reposition

#

There are over 200k meshes

plush yew Sep 30, 2019, 1:09 PM

#

(if you can actually move around the viewport)

tame delta Sep 30, 2019, 1:09 PM

#

most of them are fine

plush yew Sep 30, 2019, 1:09 PM

#

hm, why do you have to reposition them?

tame delta Sep 30, 2019, 1:09 PM

#

But I said my problem is fixed, you brought it up again and decided to rail on me, I'm good now thanks, take your anger out on someone else.

plush yew Sep 30, 2019, 1:09 PM

#

i think i know whats going on 🙂

tame delta Sep 30, 2019, 1:09 PM

Because the mesh came out bad and I had to modify it in Blender

#

(that wont ever happen again btw you are now blocked)

#

my apologies

#

can i store data in an asset (mesh) ?

fierce tulip Sep 30, 2019, 1:13 PM

#

depends on the data

tame delta Sep 30, 2019, 1:13 PM

#

@plush yew I suppose a decent way to do it would be to extend the class with what you need (perhaps a data dictionary), but that would only inherit from a Mesh

#

(don't mind me just having a laugh)

#

That's what Datasmith does

plush yew Sep 30, 2019, 1:14 PM

#

its several datatypes, so basically a struct or multiple variables

#

its data that kindof belongs to the mesh which makes it feel correct to store it there, but i'm biased as i did this before in unity

#

maybe there is another way in UE4 that is conveniant

tame delta Sep 30, 2019, 1:15 PM

#

Separate global dictionary for sure

fierce tulip Sep 30, 2019, 1:15 PM

#

I dont have much experience with it, besides using uv channels to store vertex location data thats read by a material function to change their locations

#

not sure if that would be more #graphics or code related.

plush yew Sep 30, 2019, 1:16 PM

#

well as of now im just trying to store the data

#

i figured this part was for this channel and the next for blueprint or cpp

tame delta Sep 30, 2019, 1:16 PM

#

Tell him to store a dictionary on a separate actor acting like a service

#

Oh unless he means "default" data that's editable in UE, then definitely would need to extend the class 🤔

fierce tulip Sep 30, 2019, 1:17 PM

#

Cafe had a suggestion in his last two comments, not sure if that helps.

plush yew Sep 30, 2019, 1:18 PM

#

probably not

fierce tulip Sep 30, 2019, 1:19 PM

#

https://docs.unrealengine.com/en-US/Gameplay/DataDriven/index.html would that help?

Data Driven Gameplay Elements

Driving gameplay elements using externally stored data.

#

else, no clue and wait for someone who knows 🙂

plush yew Sep 30, 2019, 1:21 PM

#

yeah im googling as well 🙂

#

ideally i wanna store it without an external file or anything, but if thats not possible i can do it this way, it would just be less logical

#

its not a whole lot of data anyway, mostly categories and then some data for each category

tame delta Sep 30, 2019, 1:22 PM

#

Welp, i'm just suggesting the way Unreal devs do it to keep metadata for meshes inside of UE while also keeping the ability to us it as a static mesh. But I suppose he didn't specify if he wants to store data in Editor or at runtime, the latter is easier and doesn't require an external file at all

rotund scroll Sep 30, 2019, 1:27 PM

#

what was the original question?

tame delta Sep 30, 2019, 1:29 PM

#

He wants to store data in Meshes

rotund scroll Sep 30, 2019, 1:29 PM

#

what type of data?

safe forge Sep 30, 2019, 1:29 PM

#

you can use attributes in houdini to do it 😉

#

and bridge with houdini to unreal engine plugin thingy 😉

tame delta Sep 30, 2019, 1:30 PM

#

Does Houdini make custom Mesh classes?

rotund scroll Sep 30, 2019, 1:30 PM

#

I mean you would need a custom class anyway unless you wanna change the mesh actor in the engine

safe forge Sep 30, 2019, 1:31 PM

#

i dont know sorry, but they use attributes, which are like custom variables, that can be attached to meshes

#

they can then be used to drive effects in niagra for example

tame delta Sep 30, 2019, 1:31 PM

#

@rotund scroll Yeah i reckon too, unless he just wants to store mesh-specific info at runtime, I'd just use a global dictionary stored somewhere for that

safe forge Sep 30, 2019, 1:31 PM

#

yea

#

you could use a map in bp?

tame delta Sep 30, 2019, 1:32 PM

#

Yeah, could never tell the difference between a map and dictionnary myself

rotund scroll Sep 30, 2019, 1:33 PM

#

I'm still not certain what type of data he's looking to store

plush yew Sep 30, 2019, 1:33 PM

#

@rotund scroll several datatypes, strings, ints, maybe even material list

rotund scroll Sep 30, 2019, 1:33 PM

#

but... why?

plush yew Sep 30, 2019, 1:34 PM

#

because the data belongs to the mesh

#

it seems logical

rotund scroll Sep 30, 2019, 1:34 PM

#

material lists are already available in the current mesh actor

plush yew Sep 30, 2019, 1:34 PM

#

like i explained i did this before in unity, where you can jsut make a struct any way you want

#

for UE4 there might be different ways

rotund scroll Sep 30, 2019, 1:34 PM

#

not sure why you'd need custom strings or ints in it

plush yew Sep 30, 2019, 1:34 PM

#

material lists that i define manually

safe forge Sep 30, 2019, 1:34 PM

#

@tame delta I believe its the same thing just different names, its even called a dictionary in brackets

rotund scroll Sep 30, 2019, 1:35 PM

#

ordinarily if you wanted to create something like that, just create a blueprint actor and add a staticmesh component

#

then you can go as crazy as you want

plush yew Sep 30, 2019, 1:35 PM

#

that would be extremely inconvenient

safe forge Sep 30, 2019, 1:35 PM

#

I think hes looking at it like programming, and it makes sense from that angle 😉

rotund scroll Sep 30, 2019, 1:35 PM

#

but from a system architecture point of view it doesn't really make sense

safe forge Sep 30, 2019, 1:35 PM

#

yea i suppose doing it by type would be easier

rotund scroll Sep 30, 2019, 1:36 PM

#

why is it inconvenient to do it in a blueprint actor?

#

you can create a cpp class that does the same as well if you prefer

tame delta Sep 30, 2019, 1:36 PM

#

Can someone ask him if he wants to be able to edit that data like "defaults"? As in just change some int/string/enum in the editor?

plush yew Sep 30, 2019, 1:36 PM

#

i'd be a ton of manual labour

rotund scroll Sep 30, 2019, 1:36 PM

#

in what way

plush yew Sep 30, 2019, 1:36 PM

#

og you mean making an entirely new actor?

rotund scroll Sep 30, 2019, 1:36 PM

#

yeah a new actor

plush yew Sep 30, 2019, 1:37 PM

#

thats WAY overkill lol

safe forge Sep 30, 2019, 1:37 PM

#

@plush yew unless its due to the way your info is stored in some kind of database, it would probs be better to just create a clean data architecture

rotund scroll Sep 30, 2019, 1:37 PM

#

it's the same thing as creating a struct

#

certainly not overkill

plush yew Sep 30, 2019, 1:37 PM

#

if there is no way to store data on a mesh (or mesh actor) then i can just use a database, file, whatever

rotund scroll Sep 30, 2019, 1:37 PM

#

if you were to change the standard mesh actor that would be overkill

plush yew Sep 30, 2019, 1:37 PM

#

i dont NEED this, im just asking if UE4 has something like this

rotund scroll Sep 30, 2019, 1:38 PM

#

UE4's mesh actor has those attributes inside of it that I can see

#

if you want to create a custom struct, you can

#

if you want to create a custom class, you can

plush yew Sep 30, 2019, 1:38 PM

#

you misunderstand

#

you focus on "material list"

#

the type of material list i'm talking about is jsut that, not the list of assigned materials to a mesh

#

an actual dumb list of materials

#

and meaningless strings and ints

#

(that i pick myself and make no sense for the engine)

rotund scroll Sep 30, 2019, 1:39 PM

#

then a custom blueprint with a static mesh component is what you're looking at

#

you can import the data from a data base too

#

then it's mostly automated anyway

tame delta Sep 30, 2019, 1:39 PM

#

Someone ask him what the end purpose is, I feel like this might be a bit XY problematic

#

Like what kind of data, and why does it have to be mesh specific

plush yew Sep 30, 2019, 1:40 PM

#

yeah storing them all in one file or database might be the most conveniant way after all

#

with unity you can literally make any struct you want right in the editor and even enter values

rotund scroll Sep 30, 2019, 1:40 PM

#

... you can do that in unreal too

#

use the unreal struct

plush yew Sep 30, 2019, 1:40 PM

#

i meant you can do this on any mesh

rotund scroll Sep 30, 2019, 1:40 PM

#

you can then create a data table based on that

plush yew Sep 30, 2019, 1:41 PM

#

well that sounds like somethin that i could use

rotund scroll Sep 30, 2019, 1:41 PM

#

you can literally create a child class off the mesh actor class and add a struct to that and it does exactly what you want

plush yew Sep 30, 2019, 1:41 PM

#

got any links or anything to read up on it?

tame delta Sep 30, 2019, 1:41 PM

#

@rotund scroll Sorry to single you out, can you ask him what type of Data and why it has to be mesh specific?

plush yew Sep 30, 2019, 1:41 PM

#

but i'd need to use that actor for all my meshes

#

not sure if thats gonna come back and bite me yet lol

gleaming creek Sep 30, 2019, 3:11 PM

#

I suspect the answer to this question might be "are you insane for trying to do that?", but does anyone know if you can make the UE4 editor not freeze up for ages if you have an actor with an array variable with tons of entries?

#

📎 unknown.png

#

This makes the editor freeze for ages each time I select this actor or recompile its blueprint. I assume it's the editor making and/or deleting all the little entry box UIs for the values

#

It doesn't freeze if I don't make the variable instance editable

#

But if the variable isn't instance editable, then its values don't get saved with the level

serene birch Sep 30, 2019, 3:13 PM

#

I'm not sure a 2000 element array is "user friendly" to be editable in the editor

#

so maybe you should just make it that way

#

hmm, that would be an issue I suppose

gleaming creek Sep 30, 2019, 3:14 PM

#

I don't actually want it to be editable, but a run-in-editor blueprint doesn't seem to be able to change anything other than editable variables

#

At least, not permanently - anything else gets reset when the construction script is next run

#

I'd settle for any other place I can store information from a call-in-editor function

I'm really quite confused by what the above is trying to achieve?

grim ore Sep 30, 2019, 3:33 PM

his variable is called =1 heh

wary wave Sep 30, 2019, 3:33 PM

#

aye, kinda peculiar

grim ore Sep 30, 2019, 3:34 PM

#

the chicken spawns an egg and adds it to his list then sets it to =1

#

then the egg is trying to find the player and destroy the egg that is =1

wary wave Sep 30, 2019, 3:34 PM

#

no, it spawns 5 eggs at the same position, assigns the second egg to a variable, then in every egg it waits for three seconds before trying to destroy the variable egg, if the player is a chicken

grim ore Sep 30, 2019, 3:34 PM

When in doubt, put print / debug statements in all the branches to see which are being executed (or just use the debugger)

might make more sense to work out what this code is actually supposed to do, rather than try to fix it?

For my issue, I seem to be able to spawn actors freely, maybe I can just spawn 2000 actors instead of using 2000 array elements, will that slow down the editor less? 🙂

actually I assumed no, is None an option lol?

ornate hamlet Sep 30, 2019, 4:01 PM

You can set none, but it still seems to use a gamemode anyways

grim ore Sep 30, 2019, 4:01 PM

to the editor!

#

I would assume it has to be there, it's pretty important to exists for the flow of default objects

ornate hamlet Sep 30, 2019, 4:02 PM

#

I am making an MP game. So I guess I need to make a new gamemode for the main menu that clients have

grim ore Sep 30, 2019, 4:02 PM

actually you can't set it to none, if you mean the override then None mean no override

ornate hamlet Sep 30, 2019, 4:02 PM

#

Ohh, yeah I meant the override

#

I thought it would just overwrite whatever is there with null

grim ore Sep 30, 2019, 4:02 PM

#

and yes having a separate game mode for main menu/widget levels is good

#

it's the easiest way to not have a player spawn lol

ornate hamlet Sep 30, 2019, 4:03 PM

#

Yeah because all my Server logic is triggering in the main menu since its using the Server Gamemode. And clients have authority on the main menu since they are the server I guess

serene birch Sep 30, 2019, 4:06 PM

#

there isn't much value in tweaking ALL the code that uses the gamemode to check if there is even a gamemode set

#

when you can more easily just set a gamemode that doesn't do anything

Hello folks. Is there any way to have a deep Call Stack check for Unreal 4?

I want to see where a function is supposedly repeat calling itself and it's preventing me from opening my project in 4.23, while it was fine in 4.22.

A few friends from here tried to help yet I am unable to pin point why it is failing and which function is repeating itself.

Any help is appreciated. ^^'

@rotund scroll thanks thats definitely very useful, i gotta think things over but i'll most likely use that (was afk in the meantime)

95% BP and some c++ here and there

Performance wise, is there any difference between box or capsule or sphere collisions

#

And how much of a hit would it be to build a compound collider to match the mesh better? Like a big capsule and a little capsule nested together for one body part?

wary wave Sep 30, 2019, 4:54 PM

#

A) Yes. Sphere is cheapest, then box, then capsule. Whether it's enough to matter is another question.
B) Totally depends on what you're actually doing.

crude vessel Sep 30, 2019, 4:58 PM

Good to know that, thank you Ambershee!

Well my characters leg for example, a box or capsule wouldn't follow the mesh very close, but I can use two capsules and fit the shaper closer, so I'm wondering how much of a hit is that, vs one, vs a mesh based solution.

grim ore Sep 30, 2019, 5:00 PM

@lucid jetty no idea if we can help but the issue is when it's getting the light and shadow maps, do you have a lot of levels? you could try deleting the builddata files from each level and the intermediate/build folders and rebuild.

it might be, its trying to load up the light maps for the level. Are you using static lighting?

its loading up the light map textures into the world settings and recursing on loading it up for some reason

#

and it "seems" like it's trying to load from disk so it's an existing file that is the issue

lucid jetty Sep 30, 2019, 5:03 PM

#

I am glad you are with me on this one. I am not a C++ master but I always wondered "why is it doing ANYTHING with light and shadow stuff?"

#

I dont have a single point light in the scene

grim ore Sep 30, 2019, 5:04 PM

#

have you ever hit build?

lucid jetty Sep 30, 2019, 5:04 PM

#

I never did, because it never asked as I never used any point light

#

I will try and see what the heck will change -_O

grim ore Sep 30, 2019, 5:04 PM

#

any light, doesnt have to be point lights, can be built

lucid jetty Sep 30, 2019, 5:04 PM

#

yeah, I got zero

grim ore Sep 30, 2019, 5:04 PM

#

https://i.imgur.com/20xDtJR.png

#

if you find your maps see if you have builtdata, if so you can delete it

#

the engine will recreate it. it's my only thought on this one

lucid jetty Sep 30, 2019, 5:05 PM

#

I will see what I can do, thank you for giving me some ideas Mr Mathew!

grim ore Sep 30, 2019, 5:06 PM

#

yeah beyond that I dunno lol, its basically trying to load up the light map data into the editor and failing for some reason

#

its possible its an actual bug with no light map data being present and using 2D so don't discount that lol

lucid jetty Sep 30, 2019, 5:07 PM

#

Exactly. Well this weird issue started up after I transferred to 4.23 . And we all know how many "beta stuff" they added in

hoary mason Sep 30, 2019, 5:08 PM

#

I would say, you shouldn't change your engine version if you are building a project with it.

lucid jetty Sep 30, 2019, 5:09 PM

#

Uh, Mr Josai, I am creating a template for everyone to use so, I am afraid it's not really a solution for me. T-T

plush yew Sep 30, 2019, 5:15 PM

#

@lucid jetty and make a backup just in case you did not yet lol

#

(jsut making sure :-p)

lucid jetty Sep 30, 2019, 5:16 PM

#

Cheers for the tip. Unfortunately in a brand new level with lighting included, I am still getting the same crash log. Sometimes it be like that folks.

hoary mason Sep 30, 2019, 5:19 PM

#

and you deleted the builddata?

lucid jetty Sep 30, 2019, 5:19 PM

#

yap

#

the thing is, my template is around 600MB zipped. Even if I make a crash report, the chance of getting a "did you try this in a brand new project?" question is pretty high

#

so I am in sad seas, sailing in sorrowful clouds, hoping for a shore

plush yew Sep 30, 2019, 5:27 PM

#

removing or rebuilding lightmaps did nothing at all?

lucid jetty Sep 30, 2019, 5:28 PM

#

nope. there are no lightmaps to built. I even tried it on a basic level of unreal's.

#

my previous level even had less, one post process volume

plush yew Sep 30, 2019, 5:30 PM

#

the only thing i could suggest is rebuilding with visual studio like someone said earlier

#

that fixed one of my projects that broke somehow moving engines, but i had another problem

lucid jetty Sep 30, 2019, 5:31 PM

#

I did rebuild but it only builted C++ files, which were successful. And unfortunately I don't know how I can check "deep blueprint errors" with it. 😦

#

Here is an interesting thing.

#

If I open the Template with a "untitled" map, aka no map assigned to spawn when project opens, it's all fine.

#

I can roam around the blueprints, none of them has any compile error etc.

#

Then I open the level that contains the "Get all Actors of Class" node which contains the big guy that spawns stuff one after another, and bam, I get crash.

plush yew Sep 30, 2019, 5:34 PM

#

does that contain the c++ from the other folks?

#

i mean nodes they made in c++

uneven fractal Sep 30, 2019, 5:34 PM

#

is world serialization possible with just blueprint?

plush yew Sep 30, 2019, 5:35 PM

#

@lucid jetty did you try adding that BP to a new map to see if it crashes there as well?

lucid jetty Sep 30, 2019, 5:36 PM

#

Ofc. I tried uncountable stuff mate.

plush yew Sep 30, 2019, 5:36 PM

#

i know the feeling lol

lucid jetty Sep 30, 2019, 5:36 PM

#

I feel like playing Darkest Dungeon with Unreal 4.

#

"Oh your journey seems to be fine OH MY CRITICAL DAMAGE MAAAATE"

plush yew Sep 30, 2019, 5:36 PM

#

but sounds like you got it fairly pinned down already

#

if that BP works in en empty map that means its likely not an actor that gets read that causes it, but rather the BP or something in it

#

do you not get any blueprint error?

visual pawn Sep 30, 2019, 5:38 PM

Hello 👋
Im new here, just joined. Im in a real dilemna about which game engine to choose and well ive came down to conclusion that i want to try Unreal to make my very first game 😅

How hard is it to learn how to use the engine to the point of making a game? I dont want to make a Triple A title right of the bat, but ive been thinking about a game inspired by "Sid Meier's Pirates".

lucid jetty Sep 30, 2019, 5:38 PM

#

Nope. Not even on packaging. This is like strange as heck.

plush yew Sep 30, 2019, 5:38 PM

#

so you can click it and pinpoint the exact node

#

i mean while running the project

lucid jetty Sep 30, 2019, 5:38 PM

#

Hm.

plush yew Sep 30, 2019, 5:38 PM

#

if you run it in editor you can leave the BP open even

lucid jetty Sep 30, 2019, 5:39 PM

#

Thats an interesting idea that can make one go "what the heck mate?"

leaden mauve Sep 30, 2019, 5:40 PM

#

How hard depends how deep you go @visual pawn - I'm new to this myself, and i'm going full monty into a RTS. So far i've been confused, frustrated, had revelations, but in the end it's a learning experience and stuff sticks! Besides that, i'm lurking in here a lot, cause even though something might not be relevant to me, people are great at explaining things to one another, so again - some things stick 🙂

plush yew Sep 30, 2019, 5:40 PM

#

from what you tested it seems the BP is causing it so its likely you should get a useful error

lucid jetty Sep 30, 2019, 5:40 PM

#

you are correct, in the end we press on. The whole reason we fall is, so that we can rise.

plush yew Sep 30, 2019, 5:41 PM

#

have you been only testing with actual builds or something?

visual pawn Sep 30, 2019, 5:41 PM

#

@leaden mauve that is actually a nice response. Back on a Dev discord server ive gotten responses like "Dont be too optimistic", or "longer than you think" mostly responses that turned me down tbh.

plush yew Sep 30, 2019, 5:42 PM

#

@visual pawn try to chop it up into manageable small pieces that you can learn and make step by step

visual pawn Sep 30, 2019, 5:42 PM

#

I imagine that RTS games are hard-er to make, more coding i think? But yeah coding 😅 gonna have a lot of frustration with that

plush yew Sep 30, 2019, 5:42 PM

#

you'll get used to blueprints pretty quick

leaden mauve Sep 30, 2019, 5:43 PM

#

It IS hard, @visual pawn - But with your scope already being "Not trying to make a AAA-game" you're already realistic. From that point, you can only do well.
I was told to maybe start with 2D platformers or some Tower Defense-things, but since they dont interest me, i went head over heels into the RTS. It's .... elaborate, but interesting, which keeps me motivated 😄

#

I made a rock in Blender and a friend of mine said "Well, it could also be a potato" - that's kinda where i'm at 😂

visual pawn Sep 30, 2019, 5:44 PM

#

Right now, my goal would be honestly to just get fundamentals, so basically just movement on a plain.

I think that im going into a rather good project to learn from. "Sid Meier's Pirates" is a game that the main game is from a more top down view, but you have on land battles like Civ and Age of Wonders. You have a simple fencing mechanic etc. 🤔

#

oh yeah, ill need to learn how to 3D

#

im but a concept artist atm

plush yew Sep 30, 2019, 5:45 PM

#

@leaden mauve you could use cubes and code the game logic with that, then add meshes and animate them and whatnot, if you're more of a coder

leaden mauve Sep 30, 2019, 5:46 PM

#

UE4 has a builtin top-down template. I suggest (if you're super new), try finding some tutorials that are making KINDA what you want in functionality - that's what i do, only to understand how and why things are connected

#

Thanks @plush yew - i'm using pyramidshape and tube as "proxies" 😄

visual pawn Sep 30, 2019, 5:46 PM

#

^ that is what i plan to do. Use cubes to get the movement, simple mechanics and then place on that models and animations, i mean...that sound like a more logical way to approach it 🤔

plush yew Sep 30, 2019, 5:46 PM

#

tube lol

visual pawn Sep 30, 2019, 5:47 PM

#

@leaden mauve i will definitely be looking into tutorials ^^

#

alright, i think i have every thing i would want to know ^^ thanks !

im on a modding project for skyrim, and they will be doing ships. Also we have a awesome guy that is a Modeller and i can learn from him

but yeah, i will have to do all the ships xD

coral folio Sep 30, 2019, 5:52 PM

#

Guys we seriously gotta up our game in terms of third party usability , theres so much good stuff being made from in unity compared to unreal

#

I wonder why ? C++ ?

#

Physics simulation stuff and procedural geometry especially

#

Currently very far away from unreal

fierce tulip Sep 30, 2019, 5:53 PM

#

lol

coral folio Sep 30, 2019, 5:54 PM

Aside from the chaos thing, but even that is nowhere close to be a physics simulator for all sorts

woeful canyon Sep 30, 2019, 5:54 PM

#

Has anyone used volumetric video using the Kinect?

fierce tulip Sep 30, 2019, 5:54 PM

#

recently physics had a massive overhaul, (beta?) and you could do proc. geo for years

plush yew Sep 30, 2019, 5:54 PM

#

@visual pawn i was beta testing for a pirate mmo a long time ago, and i recall from then the modders would buy blueprints for the bigger ships, maybe you can still get them (dunno pricing but it was reasonable iirc)

coral folio Sep 30, 2019, 5:55 PM

#

Hey Luo :) yes u can do, but I wonder why is nobody developing tools as such?

#

I do look at a lot of FX and stuff but I always end up following tutorials and get stuck in complications

#

I wonder why nobody is developing these sort of tools that helps artists

#

As a non coder I do love blueprint but it is limiting at times

dry moon Sep 30, 2019, 5:57 PM

50/50 quite some functionality is already available and in other cases very niche.
so unless its profitable or someone already made something for their own project odds are small they will be available.

Unity lends itself incredibly well for extentions through plugins and stuff

gilded igloo Sep 30, 2019, 5:59 PM

hey guys, is there a way that i can see a procedural mesh from both sides?

coral folio Sep 30, 2019, 5:59 PM

#

Whereas unreal thus far seems more liked in with it own toold

plush yew Sep 30, 2019, 5:59 PM

#

its very flexible but less performant imho

#

but the guys at unity are lying about enlighten no longer being a product, saying they will remove it (with vague promises about replacing it)

#

that kindof made me come back to UE lol

grim ore Sep 30, 2019, 6:25 PM

#

@gilded igloo chances are you want to make the material it is using 2 sided or you will have to duplicate the geometry in the opposite order so it faces the other way (not recommended)

dry moon Sep 30, 2019, 6:26 PM

#

How do I stop this STRETCHING SHIT AHHH

warped tangle Sep 30, 2019, 6:30 PM

#

are you moving the bones around or something? pretty sure that's expected behavior

dry moon Sep 30, 2019, 6:31 PM

#

Stretching is normal?

#

Nah i just simply made the bodies using the Body creation

#

moving around the constraints and collision still stretches it

warped tangle Sep 30, 2019, 6:32 PM

#

I'm not a wizard on this, but I'm pretty sure the stretching has to do with the way it was skinned, how the geometry was weighted to a particular bone right? I don't think changing the constraints/collisions is going to affect how it stretches

dry moon Sep 30, 2019, 6:35 PM

warped tangle Sep 30, 2019, 6:36 PM

#

Again I dunno, but instead of moving a bone around have you tried rotating?

dry moon Sep 30, 2019, 6:36 PM

#

I wasn't really moving a bone, but rotating works fine. Just the physics asset stretches

#

I'll repaint the skin

#

see if that helps, thanks

brave salmon Sep 30, 2019, 7:01 PM

#

how come widget's prepass eats 50% of my game thread time? from 60 to 30 FPS...

#

I admit there are 2k widgets, but they are hidden... Unless i make them collapsed fps is down

grim ore Sep 30, 2019, 7:05 PM

#

hidden still has to do the layout pass for them

#

the parent still has to determine where they go even if they are not visible

brave salmon Sep 30, 2019, 7:06 PM

#

is there a way to fix/walkaround it?

grim ore Sep 30, 2019, 7:06 PM

#

you collapse them

brave salmon Sep 30, 2019, 7:06 PM

#

I have to show them

grim ore Sep 30, 2019, 7:07 PM

#

if they are hidden they are not visible right?

brave salmon Sep 30, 2019, 7:07 PM

#

that's the point of widgets you know 🙂

#

I can't always hide them

grim ore Sep 30, 2019, 7:07 PM

#

hidden means do not draw them but do the layout pass on them, collapsed means do not draw them and do not do the layout pass on them (they take up 0 on screen)

brave salmon Sep 30, 2019, 7:08 PM

#

so is there a way?

grim ore Sep 30, 2019, 7:08 PM

#

is there a way to do what?

brave salmon Sep 30, 2019, 7:08 PM

#

to fix the FPS loss

#

when I have to show those widgets

#

I got the idea with collapsing

grim ore Sep 30, 2019, 7:09 PM

#

You can try using a retainer box if the items will not be updating

#

or just don't show 2000 widgets, condense them into less widgets perhaps

#

This might not be an implementation you can "fix"

warped tangle Sep 30, 2019, 7:09 PM

#

2000 widgets? I want to see your game.

brave salmon Sep 30, 2019, 7:11 PM

#

retainer box seems promising

#

I remember working with it as for a material wrapper, but I also remember it can change render tick

#

thanks bro! @grim ore

#

@warped tangle easy. just make a huge online shop without filtering 🙂

warped tangle Sep 30, 2019, 7:13 PM

#

I got an idea for a game. It's like speed, if your FPS goes under 60 you blow up. The goal is, how fast can you render 2000 widgets without dropping below 60. Gotta be strategic about how many you call at a time.

grim ore Sep 30, 2019, 7:14 PM

#

even with a shop you can use the list box to only show X widgets at a time it shouldnt need to keep 2000 rendered

warped tangle Sep 30, 2019, 7:14 PM

#

scaled by your system hardware of course

grim ore Sep 30, 2019, 7:15 PM

#

shop has a page, page shows 10 items, next page show the next 10 items. limited amount of widgets needed in total. win

high inlet Sep 30, 2019, 7:38 PM

#

Ah. Tks

warped tangle Sep 30, 2019, 7:39 PM

#

The issue with large levels is the further you get away from origin (0,0,0), the more inaccuracies you are going to have, and you are going to start getting inconsistencies/unexpected behavior.

#

Think of ways to fake it, because making a 100km long level is going to bring in a lot of issues. Put in some turns, travel up and down a smaller level etc

high inlet Sep 30, 2019, 7:40 PM

#

@warped tangle but not exists a technique called world composition in ue4?

warped tangle Sep 30, 2019, 7:41 PM

#

yes, which has it's own bucket of fun 🙂

high inlet Sep 30, 2019, 7:45 PM

But if I make a game like endless runners ... I will ... have the same problem?

snow thorn Sep 30, 2019, 7:46 PM

#

any idea why console command PlayersOnly would freeze my player? i cannot move, look around, nothing. pretty much everything this command should not do. my input is bound via input events. as far as i understand the PlayersOnly command affects Event Tick only so ... i'm confused. googling did not show up anything helpful

hoary mason Sep 30, 2019, 7:50 PM

#

endless runners don't walk endless. They walk on a position and let the objectives come to them.

warped tangle Sep 30, 2019, 7:52 PM

#

not 100% accurate, it depends on the intended gameplay

sly coyote Sep 30, 2019, 7:52 PM

#

When using level streaming wouldnt that just start over fresh at the streamed levels new position tho?

hoary mason Sep 30, 2019, 7:52 PM

#

yeah depends on the game but usually the endless runner anybody knows works like that

sly coyote Sep 30, 2019, 7:53 PM

#

Rather wouldnt level streaming fix that issue with getting to far from 0 0 0

crude vessel Sep 30, 2019, 7:53 PM

#

From what I read with level streaming, you have to enable repositioning the origin

warped tangle Sep 30, 2019, 7:54 PM

#

There is something called....world re-origin or something I dunno, never used it, but that should handle that. Though I've read some issues with that as well

crude vessel Sep 30, 2019, 7:54 PM

#

And it seemed to be a periodic thing based on distance, yehw world te origin

#

But my ynderstand is using that with multiplayer can be an issue, if that's a concern.

hoary mason Sep 30, 2019, 7:55 PM

#

And with a lot of objects it have some performance issues if I remember correctly

high inlet Sep 30, 2019, 7:55 PM

Each track mus to be a maximun of 70km ..not in straight forward. But with curves.

crude vessel Sep 30, 2019, 7:57 PM

Oh can soneone point me to some definitive answer on the world's most pressing mystery? Do modern video cards /UE4 actually require square textures (10241024) or could you use 20481024 without issue?

high inlet Sep 30, 2019, 7:57 PM

#

70km its equivalent a more or less 3 hours of riding a bicycle. lol

crude vessel Sep 30, 2019, 7:58 PM

#

Not everything has to be 1:1 scale in many games they fudge the distance scale

#

In the same idea, day and night cycles are never really 1:1

Yeah. I know. But I was pedalling in real life to control the pawn. And must to reflect the real scale.

at 4:20 they talk a bit about it

crude vessel Sep 30, 2019, 8:00 PM

Yeah that's what I was referring to

I will watch it later

#

Good summary of some of the tricks

#

Not the only way to tackle it but a good idea of the challenges, and really depending on your scale and resolution, 100km might be no easier than 100,000,000km

and here's a visual demonstration what the problem looks like 😉

According to the internets if it is not power of 2 you wont get mip maps. as for it needing to be squared I believe it can be rectangle as long as the sides are power of 2. the easiest way to check is to use a rectangle power of 2 texture and see if it can mip map correctly. I also believe this is all Engine requirements due to it being more efficient on the GPU @crude vessel

crude vessel Sep 30, 2019, 8:02 PM

#

Humm, that's what I was worried about. I understand the power of 2, I'd never do arbitrary resolution, but some textures could benefit from being rectangular

hey. i am making a space game. and I wanted to have some stars in the background.. the zoom/warp effect. I have coded it before in javascript (pixel drawing). Is it possible to do something like that (i dont know some sort of changing background material)?

crude vessel Sep 30, 2019, 8:02 PM

#

UV layout and textel density, but I guess I'll stick with square..

grim ore Sep 30, 2019, 8:03 PM

#

@crude vessel oh yeah it's fine with in being rectangle plus in later versions you have options to "power of two" a texture and it will resize it by padding and make it power of 2.

crude vessel Sep 30, 2019, 8:04 PM

#

Yeha I always do power of two

#

I just kind of hate to use four times the texture memory when two times will do :)

grim ore Sep 30, 2019, 8:04 PM

#

I just tested in .23 with 2 textures, non pot and pot both rectangle (1024x512 or 511) and the editor in UE4 definitely does not like the npo2 but is fine with the rectable po2

crude vessel Sep 30, 2019, 8:04 PM

#

4096x4096 seems so decadent, but certainly I could find 2048x4096 alright for some things

#

I'm just worried there is a performance cost of non square

#

Like am I shooting myself in the foot

grim ore Sep 30, 2019, 8:05 PM

#

nah non square is fine as long as its Po2 so it's optimized

crude vessel Sep 30, 2019, 8:05 PM

#

Certainly the coordinate Math is simpler with squares

fierce tulip Sep 30, 2019, 8:06 PM

#

its the same if you consider sizes percentages instead of pixels

crude vessel Sep 30, 2019, 8:06 PM

#

I was wondering if packing 4 maps into. Larger texture was better than a smallerulti channel map

#

I know you can do UV offsets in the shader

grim ore Sep 30, 2019, 8:07 PM

#

toss a few textures of odd ratios and sizes into UE4 and check them out in the editor. you can see the memory footprint and sized and such

crude vessel Sep 30, 2019, 8:07 PM

#

Like I read alpha channel is kind of expensive

grave nebula Sep 30, 2019, 8:07 PM

#

@crude vessel Rectangular textures are only concern on mobiles.

crude vessel Sep 30, 2019, 8:07 PM

#

Ah

grim ore Sep 30, 2019, 8:07 PM

#

^^

crude vessel Sep 30, 2019, 8:07 PM

#

So that's not a concern for me (heh)

grim ore Sep 30, 2019, 8:07 PM

#

and only for texture uses, UMG does not care for the most part of size or rectangularness

#

and yes alpha tends to use more memory so avoid it if you can, and texture packing and using UV's tends to be better "in some cases"

#

its all about platform and use

crude vessel Sep 30, 2019, 8:09 PM

#

Well I had done some modding for a custom engine

#

And they had a hard cap on 4 color tint maps

#

But I'm never satisfied and learned I could hack the shader to divide the mapping into quadrants

grim ore Sep 30, 2019, 8:10 PM

#

yep yep

crude vessel Sep 30, 2019, 8:10 PM

#

So I just loaded 4 textures into a single 4096 texture

grim ore Sep 30, 2019, 8:10 PM

#

packing multiple 1024x1024 into 4096x4096 is doable just got to make sure your target platform this is more efficient for

crude vessel Sep 30, 2019, 8:10 PM

#

And omitting the alpha map, I think it might have been more efficient

#

My question is, is there a proper file format for single channel textures?

grim ore Sep 30, 2019, 8:11 PM

#

the easiest thing to do is just make every texture 8k and tell people you are targetting high end PC only and they can buy a new PC if it's slow 😛

crude vessel Sep 30, 2019, 8:11 PM

#

Like if I just need a greyscale mask, I know I can pack it into RGB

#

Haha
