Any ideas as to why my click events aren't working on my Player Controller anymore?

[worthy steppe]

Guys how do you reference from a widget inside the level blueprint...

[nova heath]

Widget?

[worthy steppe]

https://i.gyazo.com/a9ea260bbde7269e85c8bbcc94c8d4c0.png

[nova heath]

Like UMG?

[worthy steppe]

i need the slider from my options widget

UMG indeed

[nova heath]

Wouldn't it be easier to dispatch an event on the slider and recieve it on the level BP?

[fair leaf]

Hola. Is there any way to select a DataTable for multple selected CSV on import? I don't want to click the DataTable for every file

[worthy steppe]

@nova heath Could you explain what i need to dispatch and how i get that info

[nova heath]

Yeah hold a sec and I'll give screen shots

First add a custom event in your Level BP

[worthy steppe]

cool

[nova heath]

Something like this: https://blueprintue.com/blueprint/8a_74xfg/

You can make it pass a float

Actually you might need to do this in a Game Instance

I'm not sure if you can access the level BP outside the Level BP

I had this same issue prior and it's why I setup a Game Instance

[worthy steppe]

Im getting confused XD , Man trying to setup a volume slider is hard XD

I can't seem to find proper information on the internet on it

It seems like a really simple thing but not in unreal XD

[quasi lake]

I worked on a level sequencer for 1 hour

And unreal crashed

Nothing left

[vale halo]

😦

[quasi lake]

Damn holy junk

[nova heath]

I got it working

[wary wave]

oh man, if sequencer worked as intended, it would be awesome

[nova heath]

@worthy steppe It's not too bad, you have to use Event Dispatchers though

[worthy steppe]

https://answers.unrealengine.com/storage/temp/40275-level+blueprint.png

this is the design i wanted

but it just wont work as my referencing is based in the options widget

[quasi lake]

Well, I'm making some cutscenes which translates into gameplay seamlessly on finish with camera blending.

[nova heath]

MainHUD is just the name of my HUD class, inside your HUD class you need to add an Event Dispatcher

Then you add a parameter to it, a float for volume should work:

Then in your Sliders OnValueChanged event you call it like this:

@worthy steppe Not too bad right?

As you can see it works:

Ignore the blank buttons on my UI, I disabled their code to make the slider work 😛

As an added bonus you aren't listening on Tick which is a nice performance bonus 😛

[worthy steppe]

@nova heath let me try and piece this together in my game one sec,

don't run off

[river mirage]

Hey guys, why Unreal didn't uses Group hierarchy from the 3D modelling softwares, like Unity and Toolbag 3 for example? is there any plugins for that?

[nova heath]

I'll be here

[surreal viper]

is there any way to stop this magnificent engine from starting a new instance of visual studio if I double click on a c++ function node?

[wary wave]

unfortunately no, that feature seems to be broken

[nova heath]

Any idea why my Player Controller isn't recieving mouse click events?

I have Enable Click Events and Enable Mouse Over Events enabled.

The tick event is firing but the Mouse Events are not.

[tight isle]

Can you send a s of the bp for the player controller node

Screenshot

[nova heath]

Yeah

If I replace InputAction SetDestination (set to Right Mouse in project settings) with the F key event for example it works.

I've tried literally every combination of buttons in Click Event Keys, none have worked.

[tight isle]

Don’t you need to connect the key on inputaction setdestinstion to an input?

[quasi lake]

Anyone knows how to close this weird cross strings?

It's in every window

[wary wave]

I already told you it's the editor grid

[quasi lake]

So how to close it

[wary wave]

show -> untick grid in whatever window

[nova heath]

@tight isle I don't believe so.

You set the Key inside Project settings.

If I do:

Followed By:

\

Then it works

I.e. Presssing the F key causes the characters to move to the mouse position

[quasi lake]

It doesnt appear before

[ripe geyser]

Guys, I'm using 4.18 and I have a weird bug: the user interface is all scaled up (while up to 4.17 it was normal). I know that they added an option to support DPI scaling, but it doesn't make any difference if I use it or not

[quasi lake]

How to close all of them?

Seems every window I open it will show

[ripe geyser]

The interface looks like this:

[quasi lake]

@wary wave

[ripe geyser]

While it should be like this:

Did this happen to anyone else?

[tight isle]

@nova heath I’d try to remove that key binding and add a key event to the BP just to see what happens.

When you debug it do you see the click event making it through your BP?

[wary wave]

you untick it in whatever window you don't want to see it in

[gloomy apex]

I converted a BSP into a static mesh, and now whatever I put its collision settings to it alsways ignores the player pawn

[nova heath]

@tight isle When I remove the InputActions and debug even if I attach Right Mouse Button just to a print string nothing happens. i.e.:

Removing the binding in project setting doesn't seem to have any effect.

[tight isle]

That’s strange. I’m afraid I don’t know enough to be helpful here. Hopefully someone else can.

[nova heath]

This used to work, I assume a setting changed or something and broke it

@worthy steppe Any progress?

[nova heath]

Every other type of event works even Mouse Move.

[oblique fern]

Why. TF is it I close a UE project and it doesnt really close?? EVen after 30 minutes

cant open the window, cant close it but it sure pops up on the task bar

[keen birch]

Probably crashing on being closed then

[tender dome]

hi guys, i want the camera setup as shown. but when i am near any object or wall, the camera goes through it and i can see things that are inside. how can i stop it from doing that?

[restive eagle]

attach the camera to a spring arm, that should be already added by default inside the 3rd person template

[tender dome]

its already done. but still i happens

[restive eagle]

does it clip like theres no wall or it barely clips

[tender dome]

like there is no wall

[restive eagle]

then try oppening that mesh and set collision presets to block all

also when your spring arm is selected make sure there is a thick on "do collision test"

[tender dome]

where can i find that option of collision?

[restive eagle]

http://prntscr.com/hz3yt1

[tender dome]

lemme see!

[restive eagle]

and make sure that your mesh has some collisions added already
http://prntscr.com/hz3zou

[tender dome]

im using defult mesh so there is no option for that!!

[restive eagle]

then inside your map click on it and look under details panel

which collision is set

it can be default and it would still work, try changing to block all to see if anything changes, if not then do the thing with spring arm i wrote before

if it still doesnt work open your character bp, click on spring arm and send an image of all your screen

[tender dome]

it keeps opening this tab

[restive eagle]

when you do what?

this is not needed

[restive eagle]

and show which wall inside your game is not blocking

just the in game image is enough

[restive eagle]

oh a bsp

havent done anything with them so give me a sec to test

[tender dome]

even with cube static mesh from modes panel

[restive eagle]

hmm by default this box is blocking my camera

[tender dome]

maybe its the placement of camera!!

[restive eagle]

well if you tested properly then it shouldnt be a problem

if you are getting some kind of block looking in a lot of different directions then probably

ideally you would want to set your spring arm like this
http://prntscr.com/hz47nq

that it would go dirrectly to the character

[tender dome]

this is whats happening

[restive eagle]

your camera location should be on 0 0 0, and by setting socket offset for your spring arm you can move it arround

honestly hard to tell whats wrong, if no one else can gie another advice i would recommend oppening a clean 3rd person template and test it there

if it works correctly there try to look what kind of changes you made to cause that kind of problem

[tender dome]

first lemme check using socket offset

[restive eagle]

socket offset helps with narrow spaces, encountered that while going through a door

but no matter what, objects were still blocking my view, in your case they dont so its another issue

[tender dome]

even with cam on 0,0,0 and using socket offset it still happens

[restive eagle]

ye so open a clean template and test it there

you made smth that is causing that, for anyone else its hard to backtrack unless they encoutered the same issue

[tender dome]

okk ill do that

is it importent for mesh to be on 0,0,0?

[restive eagle]

um Z shouldnt matter much, depending on your mesh. but if you move from the x,y then maybe you would get some clunky movements. mine is on 0 0 -100

[tender dome]

im thinking of keeping spring arm and cam at origin and moving mesh

didnt worked! X(

ill use clean temp now!

yup! still happening 😦

[restive eagle]

hmm very strange

just made a clean template of my own, no some sort of problem so cant help you sorry

[tender dome]

now thinking of decreasing arm length

didnt worked either

[nova heath]

I've solved my issue but I don't understand why it happens

Other actions were happening on Left\Right Mouse Button Events

Removing those actions caused the movement to function again.

[tender dome]

btw i wanted camera like this!!

any idea how can i get this kind of angle?

[flat pilot]

I'd like to target a 2d render of a 3d actor ingame ( kind of hard to explain so here is a screen ), I just need a function name and I'll start digging on it, can someone help me with that ?

[livid haven]

That's not really going to boil down to a single function in any way.

You're going to want to do some fancy depth/stencil work with materials.

I don't off the top of my head have a resource to give you. Tom Looman has something where he touches on depth/stencil writing/reading to make a see-outlines-through-walls effect.

So you can try finding something about "outlines" or "x-ray vision" or "see through walls" in conjunction with "Tom Looman"

[flat pilot]

I'd think that it's something people need a lot, was looking for an obvious function

[livid haven]

?

No, this is a pretty particular visual effect.

[flat pilot]

at first I thought it was the "render 2d canvas" thing

ok ok thanks

[livid haven]

This is inherently a shaders/materials kind of feature.

You're asking the GPU to track what pixels a particular object or set of objects were drawn to.

Then using that to mask the drawing/rendering of other operations.

It's not really a generic thing - it's a particular usage of low-level mechanisms for stenciling/masking.

[flat pilot]

the yellow border around the actor could be something to work with ?
since drawing it for the engine is basically having access to what I want ?

[livid haven]

Not exactly

But they do use some similar low-level operations, depth/stencil reading/writing.

Again, that Tom Looman example will give you some leads - you're not going to be able to copy-paste what he has and just tweak it, it's not what you want, but it touches on the things you'll need to understand and use.

[river mirage]

Hey guys, what i could do to fix this light leak? my lightmap is at 2048 res

[south ridge]

Are you building in production quality

Are your walls two-sided

[rocky portal]

is there some way to populate a list of ContextActions based on which components are present
catch is there is a set ordering of actions
right now I use a ContextMenuComponent which holds an Enum Context Actor Type and I use this to generate the ContextAction list out of a DataTable
but I end up with ridiculous ContextActorType's like: World_PickupEquipSearch
Inventory_EquipSearchDrop

seems silly to make an Enum and literally list what context actions there are inside it

I could use generic names like World_Backpack (Backpack being an equippable container)

World_Consumable

[keen birch]

Could just use arrays for that, right?

[rocky portal]

Could also come up with Suffixes like: W_EQ_Container,

I_Consumable

[river mirage]

@south ridge yeah, its production, its not two sided because my walls has thickness

[south ridge]

Are walls just touching or fully intersecting? How think is the wall?

Can you try, as a test, making the walls intersect and increasing thickness of the wall near the leak to at least 2x the texel size on that wall

In other words, for the test, try to cover up at least 1-2 texels on the wall where leak happens with the thickness of your wall (or some placeholder object)

[plush yew]

Which chat channel is best for discussion Unreal file referencing? E.g.: files losing references to each other?

[obtuse ocean]

blueprint is what?

[tender dome]

@restive eagle i found the solution. i added a new spring, rotated it to camera location and it worked but a new problem arose. now i cant rotate my cam when i am not moving!!

[nova heath]

I have no idea what you're talking about lol

[tender dome]

i fixed my "camera clipping through objects" probllem

[nova heath]

Was I a part of this conversation? I think you may have me confused with someone else

[south ridge]

@plush yew this chat 😛

[plush yew]

Excellent - quick question hopefully. I renamed a folder within the Unreal editor. Now I've got assets complaining that they're missing references to this folder.

Weird things is - some assets handled me renaming the folder fine. Others did not. I have no idea why.

I'd like to manually repair the missing references - is there a way to do this?

E.g.: a particle system outside the folder was referencing a static mesh within the folder. I know where it needs to point after the rename, but I can't find an option to repair it manually.

(I'm hoping I don't have to open each problematic asset, find the variable/setting causing the problem, and set the value from there.)

[rocky portal]

how does the spawn collision handling work

if you set it to adjust location

[keen birch]

@plush yew First off, right click your content folder and click "fix up redirectors"

And hope that fixes it

If, like I'm assuming, that doesn't fix it, I'm afraid your refs are actually completely dead, so yeah, you'll have to manually redo them

[south ridge]

@plush yew Roll back to an earlier version using your version control, MOVE assets to new folder (don't rename folder), then do "fix up redirectors" and move the assets into current version

[plush yew]

Yeah, I did the Fix Up Redirectors and that didn't do it because there were no redirectors to fix.

Gah. Reverting back and doing it again. Seems like a bit of an oversight to have a error message saying "Reference not found" without a path to resolve the problem easily.

I'll file something to Unreal. Obviously my workflow was broken, but this feels like something that should be recoverable.

Thanks for the tips though!

[south ridge]

What version?

[plush yew]

4.17.2

[south ridge]

Yeah, that's a bug. There were known issues with renaming stuff in pre-4.16

Generally you shouldn't rename folders

Only move files

[plush yew]

👍

Good to know. Thanks!

[south ridge]

Post-4.16 I had no issues ever with just moving files (but plenty with renaming folders)

In my case, folder renames would usually fail though

Moving folder "Foo" to "Bar" would end up making an empty folder called "FooBar" and files staying in the original "Foo" or other stupid stuff like that

[umbral trout]

Anyone else experience system slowdown while using UE4, has been happening since the other day with new Nvidia drivers that have meltdown patch. I'm on 4.17

[silver crown]

"Nvidia drivers that have meltdown patch"

Only CPU part is patched not GPU

Shouldn't have an impact

[gleaming shore]

Hey guys, was wondering if someone could point me in the right direction. Basically I want to create a super simple game (cube goes forward if it hits anything you die) however I just have no idea where to learn what I need

for example first thing i'd need to do is make this cube go forward on its own, but google hasnt brought anything up that helps

[silver crown]

Maybe https://docs.unrealengine.com/latest/INT/Videos/

The endless runner one

[gleaming shore]

Ah thank you, that actually helps a lot

[south ridge]

@silver crown actually the GPU drivers would be highly affected until they are properly updated (if at all)

Any sorta talking to external hardware that has to talk a lot with OS's kernel would be affected

But hopefully GPU drivers will be updated so they will be exempt from the meltdown/etc patches...

[midnight yoke]

Guys, is the UE4 blue shield logo still used officially for something?

[weary basalt]

How do you mean?

Any Epic/UE branding logos that Epic make would always be official.

[safe rose]

So

the Blue Logo IS still allowed to be used

For now anyway

I just talked to legal yesterday about it

You STILL need to submit a Trademark License Agreement Form @midnight yoke

But no

All logos are now the black and white flat one

[south ridge]

Off-topic, but I still have no idea why would you want to use extra UE4 trademarks when you're not forced to

[safe rose]

That's their new "official" one

[midnight yoke]

I think it is still used in the splash animated intro?

[safe rose]

@south ridge What are the cons in your eyes?

[midnight yoke]

^

[weary basalt]

@south ridge Id imagine some devs would like to respresent

[safe rose]

I see many pros

[weary basalt]

UE and Epic are amazing brands

[safe rose]

Yup

And they are really nice about marketing

IF your product deserves

it

[midnight yoke]

Recognizability is great

[safe rose]

Basically, if it can wow people and showcase the engine good

It's a nice kickback for everyone imho

[south ridge]

@safe rose No major cons. Only a single minor con

I think it should be irrelevant to the game what engine it's made on, so the only minor con I see is that some people don't like it

Thing is

[safe rose]

?

no way

lol

I can't agree with that at all sorry

I don't have much of a comeback though

[fierce tulip]

can also be done because of fanboyism. i'd be fairly proud to show that I used ue4 for my game. (but thats just me being a fanboy)

[south ridge]

For a big project, you're already paying Epic a ton of money compared to other engines. I think that's totally fair, but also it's a good thing that those logos are not mandatory

[safe rose]

But I think the others are going to be able to handle it just fine 😉

[weary basalt]

Engine is irrelevant if you look at it like that. But still the minority of people that would hate the engine, only an fraction of that would not play the game because of it.

[south ridge]

I don't think presence or absence of the logo would be a decisive factor in any way ultimately

[safe rose]

No, but it helps with promotion

[south ridge]

It wouldn't affect sales unless your game looks like UE4 shovelware

[safe rose]

marketing

[south ridge]

Dunno

Does it?

It never helped us so far 😄

[safe rose]

You think you can get on a MadeWithUnity website, with UE4 game?

Or viceversa

Some of these sites are pretty popular

Great exposure

[south ridge]

But let me say something

In my mind I have a big UE4 project right now. For a smaller UE4 project I totally agree

[weary basalt]

I would just put it down to personal dev preference really. Like you said its not mandatory so you do have an choice.

[safe rose]

Smaller?

Big?

[south ridge]

Putting UE4 logo on a smaller project to aid in promotion on the basis that it's a good example of how UE4 can be used is a fair idea

[safe rose]

I don't get how size would matter

[south ridge]

Big - lets say with a budget of over $150k

[safe rose]

Is that what you mean by "big" ?

Just how much you have money to spend?

[south ridge]

Because at that point you should have a marketing guy or even a team to help market your game

Not just post it on UE4 websites and put an UE4 logo on it

[safe rose]

I don't disagree, but that has nothing to do with placement or usage of their logo

[south ridge]

That is marketing, but that doesn't really do anything after a certain threshold

[safe rose]

If anything, wouldn't it just be icing on the cake to use it?

I don't know...mine's pretty big righ tnow

[south ridge]

Hey, if you can work the logo tastefully into your promo materials, it's totally fair

We can't find a place to put the logo tastefully so we decided we just won't

[safe rose]

Just make a UE4 Train?

😉

[south ridge]

Outside of credits roll/documentation stuff

[safe rose]

Black and White custom

[south ridge]

@safe rose a better idea would be putting it on an advertisement then

[safe rose]

If I could, I would make a B&W zombie

[south ridge]

Since we have advert spots in our game due to nature of the metro

[safe rose]

Ah

[south ridge]

Not real advert spots haha

[safe rose]

That makes sense though

[south ridge]

We're not gonna be putting real ads in there, but we'll comission our designer to advertise some random bullshit there in a serious manner

Fake products etc

[safe rose]

I don't know. I like seeing it in game

[south ridge]

I prefer the B/W logo stylistically

I think blue logo - and this is not related to our discussion - is ugly

But that's a taste thing, ignore that

[rocky portal]

That laptop needs IT support

[south ridge]

Point is, I'm a big fan of not having branding on everything

I asked for no branding on my laptop 😄

So it doesn't have the stupid-ass ugly logo on the front face. Just a clean slick panel

[weary basalt]

Each to their own

[south ridge]

Yeah!

[coarse cradle]

anyone know why this is happening?

the preview material is correct but for some reason the mesh is differnt

*different

[fierce tulip]

you dont have a proper uv-map on the mesh

[coarse cradle]

its just a flat surface

[fierce tulip]

doesnt matter, you need to unwrap your uv's for shaders to work on em

[coarse cradle]

hmm alright

back to blender

[fierce tulip]

good luck!

[frosty copper]

@coarse cradle The first few minutes of this aught to suffice, although the full video will be of benifit; https://www.youtube.com/watch?v=KXYqr4w6li4

[coarse cradle]

well It was the unwrapping thing

it was just a plane so all I did was go back to the model and hit "unwrap"

[fierce tulip]

yea, that would work haha

[coarse cradle]

then I just drag and dropped the diffuse and normal onto the imported mesh

[fierce tulip]

now you can add to your resume "experienced in unwrapping" XD

[coarse cradle]

works for me

[frosty copper]

Does help to understand wha-.... 😂

Luos... why you do dis

[fierce tulip]

:p

hey its a start, a plane today, a box tomorrow, a high end super model in a year

[frosty copper]

.... XD it still helps to grasp and understand what's going on. XD

else the next question will end up being "I unwrapped this cube, but all the faces are the same... why?"

[fierce tulip]

https://www.youtube.com/watch?v=sR0xV0TDvS8 while I made one mistake in the video, it does explain rather decent what uv's are and how they work.

[queen arch]

can someone help me with some vector math?

I want to find a position in front of my character and to the right, but without changing the X and the Z

I have the forward vector, but I don't know what to do with it

Fuck my life, it's working... it's working and i don't know how! It shouldnt work! The rotate to face location nodes aren't even connected!

What is happening?

Is my copy of the engine possesed?

[coarse cradle]

https://wiki.unrealengine.com/Cel_Shading_Post_Process

says in this tut that I gotta set the roughness to 1

im assuming thats something I had to set back in blender when working with the nodes ?

or is there anotehr roughness setting I have to work with in ue4?

[grim sinew]

It's in the Unreal material

[gleaming shore]

Hey guys, i made a very simple runner game however I've no idea how to make a simple points system (for example, for every 1 milisecond you're alive you get 1 point), could someone point me in the right direction?

[weary basalt]

Create an looping timer.

Simple

If your still alive when the timer ticks over then add 1 point. If not then kill the timer and stop counting points.

[gleaming shore]

Do you implement that with a hud widget?

[weary basalt]

The Timer probably shouldnt be inside the HUD, an more appropriate place would be PlayerState or GameMode (depending on SP or MP)

But you would use an Widget or the HUD to show the value of your Points yes.

UI Elements should always grab or be fed information, they shouldnt be responsible for generating it. They are only there to display information, nothing more.

[gleaming shore]

That's useful information, thank you

[coarse cradle]

dumb questions but

I dont really understand this

I made the material and Im not sure what this next step means lol

[gleaming shore]

How can I make my integer "tick up" then display on the hud, im having serious trouble with it.

https://i.gyazo.com/09c154ca12f91db804c18ac37a8fe106.png so far this is all i have

[worn granite]

set it equal to itself + Delta Seconds. if you really wanna, you can multiply Delta Seconds by another number (say, 2) to control how far "distance" increases over the course of a second.

[gleaming shore]

How do I display that information onto my hud or widget? Thanks for the reply btw

Ok i got it to display however the way im getting the info is wrong, im not sure how to make it "go up"

[weary basalt]

Simple addition.... Just as PlaceholderName explained.

You would benefit from watching some Basic youtube tutorials on Blueprint.

[gleaming shore]

I followed a tutorial however they did not show how to do the scoring. Ive googled around and most scoring tutorials are shooter based

[weary basalt]

Your not going to find an tutorial that fits your exact use case, you need to watch tutorials and absorb the information in order to think critically about your problem in order to arrive at an solution with the information you collected earlier.

What parts of that tutorial is similar to your issue and how did they solve it?

How can you adjust their solution to fit your own problem?

These are some simple questions that will help you engage with your problem solving abilities.

[plush yew]

hi

[south ridge]

hi

[plush yew]

i use paint

🤐

[coarse cradle]

is there a way to make my normal map stand out a bit more? I have a roughness of 1 set so i can use cel-shading and it makes the bumps in the floor non-noticeable

[south ridge]

You can boost your normal map

tangent_normal = normalize(lerp(vec3(0,0,1), original_tangent_normal, normal_intensity))

normal_intensity of 0.0 will remove normal map, 1.0 will change nothing. Values over 1.0 will cause normal map to become more intense

[coarse cradle]

I see whats happening

so youre essentially just multiplying the blue value by whatever you set it as?

because RGB is a vector?

[south ridge]

No, not exactly

I'm interpolating between no normals (a vector of X = 0, Y = 0, Z = 1.00) and whatever normals are there by default

If I go beyond 0 .. 1 input range, it will start extrapolating normals

And if I go below zero, it will invert the normals

In other words, I can scale the "intensity" of normal map - set scale between no normals (vector of 0,0,1) and full normals, but it can also go beyond 1.0

[coarse cradle]

hmm

I think I got what you mean

[south ridge]

This basically squishes normals to make them less or more pronounced

If you squish your normal vector, the normals will become more intense

Hold on

I'll illustrate

[coarse cradle]

alright

[south ridge]

So to scale normals we "squish" normals (or extend them upwards), then normalize to ensure they have unit length

Don't forget to normalize. If you forget to normalize, it will look correct at first, but cause unpredictable issues later

[coarse cradle]

ohhhhhh

makes a lot more sense now

[south ridge]

lerp is simply a compact way of squishing them in a way that produces easily understandable "intensity" input

Instead of doing a lerp you can do what I've drawn on the picture above

squished.y = normal.y
squished.z = normal.z*scale
final_normal = normalize(squished)```

In fact...

Take this: tangent_normal = normalize(lerp(vec3(0,0,1), original_tangent_normal, normal_intensity))

And write it out in full:

tangent_normal.x = 0 * (1 - normal_intensity) + original_tangent_normal.x * normal_intensity
tangent_normal.y = 0 * (1 - normal_intensity) + original_tangent_normal.y * normal_intensity
tangent_normal.z = 1 * (1 - normal_intensity) + original_tangent_normal.z * normal_intensity
tangent_normal = normalize(tangent_normal)

While it doesn't look quite the same, if you look at it, it is proportionally doing the same thing

But instead of simply squishing Z it squishes X and Y while growing or shrinking Z

The net effect is same. Both approaches utilize same number of GPU instructions (lerp is free), in fact lerp one might be a tiny bit faster maybe

[coarse cradle]

either ways it accomplishes the same task

[south ridge]

Use the lerp approach, but consider squishing one too for learning purposes

[coarse cradle]

when else could the squishing approach be used rather than lerp?

[south ridge]

I need to boot up mathematica, but I believe the lerp method produces (I think!) linear scaling of normals, while the squishing method is a little non-linear

But whatever. They both give same final result 😛

We use lerp in our materials to adjust normal map intensity for some materials

[coarse cradle]

I understand now

jeez thanks for this long explanation

never would have guessed how to without it

[south ridge]

You would've invented squishing method eventually after thinking about it

[coarse cradle]

woudlve taken me a damn long while lmao

*would've

[south ridge]

It is a natural choice once you think about what tangent space normal is

[coarse cradle]

thats true

tbh Im still pretty new to this stuff so I'm still trynna learn all these terms lol

[south ridge]

Next time ask this sorta stuff in #graphics 😛

[coarse cradle]

true, ill be careful

careful-er.. this is the second time lol

[south ridge]

And you can poke me for graphics questions too

I love technical artistry stuff 😄

[coarse cradle]

thatd be a great help, that's definitely my weakest area, especially with lighting related topics

thanks again

[south ridge]

Man

I should post that as a blog post

But people who follow our game get angry if I post anything that's not about our game

Btw

I just checked with Mathematica just to be sure

The squishing and the lerping methods are FULLY equivalent 😄

With one exception - the lerping method properly inverts normal

The X axis is the input factor to squishing/lerping, the Y axis is relative visual intensity of normal map (as measured by how darker/brighter the relevant pixel will be, compared to original value)

[gleaming shore]

Does unreal not let you use mp3's as sound? My blueprint wont show my mp3 sound file

[vale osprey]

@south ridge interesting, are you lerping with a 0,0,1 vector?

[south ridge]

@vale osprey Yes

And the result is mathematically identical as woflram shows (except for the sign reversal)

lerping properly inverts normals with negative "intensity"

[vale osprey]

and squishing is lowering Z of normal?

[south ridge]

Squishing is just scaling Z of the normal and letting normalization fix X/Y afterwards

This is squishing

[vale osprey]

good to know that lerping is as valid as scaling Z

even has extra feature 😄

[south ridge]

Yeah, it's very useful to invert normals sometimes

Inversion just changes the apparent shape of surface like this

You can invert normals by multiplying the X and Y components by -1 obviously

[vale osprey]

yes

[vale osprey]

It’s just nice that with lerp you can expose just one parameter and then both flatten and invert normal map

@south ridge unrelated question but maybe you have insight:
I'm trying to figure out why engineers started to skin fuselage of early ariplanes . There where couple of early airplanes that used open frames, like Wright's flyer, Demoiselle but after them pretty much all fuselage frames where completely or partially wrapped.

some sources say that it's to lower drag but from math point of view I don't see how that is possible

individual struts, wires and frames can have a higher drag coefficient because of their shape, but their area is much smaller than a fabric square attached to the side of frame

environmental factor makes sense for area around pilot seat and maybe some cargo section (which was rare)

maybe it has to do with fabric cover creating lower skin drag when airflow is parallel

hmm, that would make sense actually

[south ridge]

That is part of the physics reason

Struts, despite having lower frontal area, have higher drag coefficient

Drag force is Fd = <blah> * Cd * A

When going from struts to smooth skin, you increase A by not all that much (remember, plane has an engine and the cabin, frontal area is gonna be mostly the same-ish)

But you drop Cd by so much

In simple words, turbulence = drag

Smooth skin planes create little to no wake turbulence by their fuselage (most of wake is created by wing tips, followed by wings and tail etc)

Struts and random antennas and other junk always create turbulence behind them

Turbulence means inevitable loss of energy, means drag

[vale osprey]

that makes sense

not sure about increase in A

let me illustrate

[floral heart]

At higher speeds, would the increase in Cd be worse than an increase in A?

[vale osprey]

http://imgproc.airliners.net/photos/airliners/5/5/7/1524755.jpg?v=v40

@floral heart the same factor, the are both linear

airdrag force equation is
D = 0.5 * ro * V^2 * A * Cd

only velocity is quadratic

to be precise, Cd depends on speed too

but normally calculated/approximated for a specific flight conditions

and here is Bleriot:
https://bleriotxi.com//wp-content/uploads/1721412_orig.jpg

[south ridge]

@floral heart At higher speeds (transonic and supersonic, mach 0.5+) you HAVE to have a very specific smooth skin setup

It's completely utterly different when you get there and the only solution is literally magic

https://en.wikipedia.org/wiki/Area_rule for M0.5+

https://en.wikipedia.org/wiki/Anti-shock_body these are mostly magic, though there are reasonable explanations of why this works and why area rule is a thing

The basic principle is that if aircraft follows area rule, the airflow behind the plane ends up less turbulent and once again - less turbulence = less drag = less energy loss

[vale osprey]

I sort of get it why airplanes like Antoinette:
http://imgproc.airliners.net/photos/airliners/0/5/0/2027050.jpg?v=v40

had fully covered fuselage, I guess it lowers skin drag

but Bleriote was build around the same time and windtunnels where already a thing

yet half of it's body is left as open frames

and I can't think that engineer of Bleriot didn't know what he was doing as airplane has a number of clever ideas, like horizontal surface of the tail is placed such that it doesn't get into the wake of the wing

@floral heart I thought you mean high speeds for early airplanes 😄

[south ridge]

No skin = cheaper 😛

[vale osprey]

as Blackfox said, around 0.75 mach speed, things start to change pretty fast

[south ridge]

Later planes started to rely on aircraft skin to transfer some of the mechanical loads onto the frame itself and so on, so skin became an essential part of them

[vale osprey]

yes, that part I have sort of covered, just wasn't sure how to "penalize" player by not installing skin

like when you don't have access to load bearing skin yet

[floral heart]

I was indeed thinking of early planes breaking highway speeds. Got lost reading those links, though.

[south ridge]

Penalize them by increasing Cd as their speed grows

[vale osprey]

but now I get it, basically drag coefficient for a frame, doesn't depend much on angle of airflow, like it will be at 0.8-1.0 at any angle, while skinned fuselage will have something around 0.05 as skin drag when air moves in parallel

[south ridge]

With a quadratic (probably) proportion

[floral heart]

Any chance the extra turbulence could damage something?

[south ridge]

Yes

That's called flutter 😛

[vale osprey]

yeah, it creates drag and drag is rather strong force

[south ridge]

Flutter can be induced by turbulence/wake

[vale osprey]

"Penalize them by increasing Cd as their speed grows" I like this idea 😄

[south ridge]

Turbulence has a natural frequency (it's an oscillating process). When this flow interacts with aircraft tail, it may induce heavy oscillations if tails natural frequencies are too close

So this oscillating force (up-down-up-down) hits tail. If any of frequencies in the turbulent spectrum (it's not a single freq) match up with natural frequency of the tail (its bendyness), the tail EXPLODES

That's my favorite thing about flutter. When flutter happens, the relevant aircraft part just EXPLODES

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

[floral heart]

Sounds like it should be your least favorite thing!

[vale osprey]

@floral heart you have three basic forces in flight, weight, lift and drag. (thrust not relevant specifically in this case) Weight doesn't depend on speed but inertia can be a thing. The other too strongly depend on speed. When pilot of early airplane does a sharp maneuver, increase of angle of attack on the wing, creates more lift and more drag while mass of the airplane wants to move by inertia in old direction. Snapping wings was rather easy in those conditions.

• lift and drag act in different directions

so any bear loading joint, like struts that hold wings, will be under stress at two different vectors, with different vibration and etc

@south ridge that looks brutal 😄

[south ridge]

Most of those examples are self-induced flutter (turbulence from the wing causes wing to flutter), but some of the tail ones are related to wake turbulence from main win g and fuselage, at least partially

[vale osprey]

Antoinette took drag seriously for his new airplane:
http://longstreet.typepad.com/.a/6a00d83542d51e69e201901d599c09970b-500wi

but added weight was the issue

ok, this gets me somewhere

thank you guys for brainstorm!

[south ridge]

Anytime

Poke me if you need more aerodynamics talk

I started an aerospace company! Har har.

(it's currently so small it doesn't count though)

[vale osprey]

Thank you!

I'm in the process of making prototype for building early aviation - WW1 kind of airplanes from modules

should unload itself

[south ridge]

There are two types of levels

If you manually loaded level in, chances are, you'll have to manually unload it

That's for "blueprint" streaming levels

For "distance based" streaming, it's only based on distance to player and is fully automatic

And the distance is only measured in XY axis I believe

If your new level is located far away from the main menu level

That's assuming world composition is on

[brittle gulch]

Hi guys, I've heard somewhere that C# will be implemented in UE4 in the future, Have I dreamed?

[south ridge]

@brittle gulch pretty sure C# as a scripting extension was available for a while now?

[keen birch]

There's some community-sourced stuff happening which is adding in support for C#, F# and some other stuff iirc

[cloud cobalt]

It's not coming officially, just through community mods

[keen birch]

https://mono-ue.github.io/

https://github.com/xiongfang/UnrealCS

[south ridge]

Oh dear

Chinese programming

[keen birch]

Yeah the last one's dead I think

[south ridge]

Suddenly flashbacks to when we were fiddling with a DVB radio, turning it into a digital transmitter

[keen birch]

Think you need tjhe first one

[south ridge]

We had troubles with the drivers, so we asked manufacturer for support

They just sent us the driver source code and that's it

No more docs, no info nothing

The driver was mostly concentrated in a single 200 kb CPP file

[keen birch]

😛

Don't particularly feel like building from source though 😦

[south ridge]

Ha

I've never not built from source

[cloud cobalt]

I've built from source for some time, never again

[south ridge]

Why not? It's great

[cloud cobalt]

We don't ever want to have changes to the engine, so building from source is just a time-consuming hassle

Especially while generating releases of the game - the engine just loves rebuilding half of itself for zero reason at all

We have to do it on Linux, since Epic doesn't provide binaries, it's a fucking pain

[south ridge]

Heh I see

It's not for no reason btw

[brittle gulch]

Oh okay, so it won't be inside of the engine itself. And is it viable? To program in C# in UE4?

[south ridge]

You build debuggame or something for editor, but release is shipping

@brittle gulch just use C++. UE4's C++ is much nicer than your average C++

[keen birch]

That C# branch seems pretty solid

Can't really tell you more though

I disagree @south ridge That's a personal thing

While I know how C++ works, I absolutely hate programming in it

I prefer C# by a really wide margin

There's a reason I'm building everything in BP at this point in time

[cloud cobalt]

Personally, I'd rather depend on the least possible amount of plugins that you can

Reasons for that include the ability to upgrade and target new platforms

[wary wave]

In UE4 I don't see any advantage over C++

your gameplay code is so heavily abstracted it looks borderline identical anyway

[keen birch]

I dislike pointers pretty badly

[wary wave]

I don't think the gain in adopting a third party C# plugin is worth the problems it could introduce

you don't really use pointers in UE4 C++ though

[south ridge]

You use ~smart~ pointers

They are clever you see!

[wary wave]

gameplay code is all memory managed using smart pointers.... like C#

[south ridge]

And much more like references instead of being actual pointers

[keen birch]

Well, then either I'm an idiot or I still have to use pointer syntax

[wary wave]

you just declare vars with a pointer, that's about as far as it goes

[cloud cobalt]

The problem with a C# plugin is that maybe two years from now, you're going to want to port your successful game to the PS4, and shit - the plugin doesn't work there ! Can't port the game without rewriting it entirely from scratch.

Or you want to upgrade to UE 4.27 that has the new Vulkan 2 API but the C# maintainer has been run over by a bus and the plugin isn't maintained.

Or you want to use some new engine functionality that the plugin doesn't expose well.

Etc

[keen birch]

YEah, that's a really valid concern

But that's with some in-engine stuff as well

[wary wave]

yup

[keen birch]

E.g. SOBOL is never getting documented

Because the guy that wrote it left

¯_(ツ)_/¯

[wary wave]

SOBOL I've got working, but it seems the distribution function is actually pretty shit so don't worry about it

[keen birch]

Yeah I got it working

[wary wave]

as far as pseudorandom goes, it's pretty damned predictable

[keen birch]

It's pretty underwhelming

😛

[brittle gulch]

I was asking because I can't really code (I've justused a tiny bit of javascript for webdev but that's all). I do everything in Blueprints, and sometimes I see their limitation so I want to learn code. And I've heard a lot about the difficulty of C++ over C# so I was wondering if it was better to go with C#. But since the engine has been built for the use of C++, I guess I don't really have the choice. Plus I have being dependant of plugins

[wary wave]

like I said, the difference between C# and C++ would be negligable

[keen birch]

It's basically: (0.25, -0.25) (-0.25, 0.25) (-0.25, -0.25)

Etc

[wary wave]

UE4 gameplay code is heavily abstracted and macro heavy, it'd look more or less the same

[keen birch]

Yay for pseudo-randomisation

[wary wave]

I'll write my own psuedo-randomisation

with blackjack

and hookers

[keen birch]

Share pls

❤

Working on a cluster-based foliage generator

Wouldn't mind decent pseudo-randomization

[wary wave]

we implemented poisson disk distribution here

worth looking into for cluster foliage

small addition, but our foliage tools are already 500% more awesome than the defaults

[cloud cobalt]

@brittle gulch Blueprints go a long way, still. If you're not a code person, find one - C++ is definitely not beginner-friendly

[brittle gulch]

@cloud cobalt Yeah blueprints are great! I would continue make games in BP, but complement it with C++ would allow me to access to more functionality I guess. For instance, I always wanted to have access to my collision shapes informations and that's not really possible in BP because they are not exposed. I guess in C++ I'd have access to them right?

we don't know because we don't know anything about your landscape - but that link will help ^

[keen birch]

You literally just got the link explaining that

[wary wave]

"Landscape is 1 vertex per meter. This is 100 UE4 units per landscape vertex. So a landscape size of 4033 vertices is 4033 meters, or 4.033 km. Pretty basic."

it's right there in the thread

(at default scale)

[keen birch]

@wary wave Can you say anything about your foliage tools? Kinda curious. Custom engine version I suppose?

[wary wave]

they're built as a plugin rather than custom engine, but I can't say much about it

hi all

[tropic pilot]

does anyone know of any tutorials (pref youtube) that covers how to make a character jelly like but still moveable like (Gang Beast or Stick Fight: The Game)? ----> like this https://www.youtube.com/watch?v=wsSgZn5yhKA

[wary wave]

I don't think you're going to find tutorials for that

[tropic pilot]

that sucks :/ realy want to learn this! want to mess arround with the idea and pref make a simple game out of it to just fiddle with

[wary wave]

'change the colour of 3d objects' - err, what do you mean?

then you want to look at the materials

[honest vale]

@light lintel have you read the documentation at all?

like, any tutorials?

meshes don't have colours

[cloud cobalt]

@light lintel Meshes have materials, which control the color.

You need to create a dynamic material that has a color parameter

Set that material to the mesh that needs to change color

And change the color parameter with Blueprint

Take a look here for what materials are : https://docs.unrealengine.com/latest/INT/Engine/Rendering/Materials/IntroductionToMaterials/index.html

For parameters, look here : https://docs.unrealengine.com/latest/INT/Engine/Rendering/Materials/MaterialInstances/index.html

not to be rude, but you should probably run through some tutorials before asking really basic questions like these in Discord, since this kind of thing is well documented

hi guys question.. i already move this 2 (yellow circle) in different folder.. and i try to delete the old one.. is there any effect of my project if i delete the old one ?

[flat pilot]

dumb question here, hud works but I can't draw on it, what's wrong ?

[keen birch]

They kinda botched the volume on that stream, didn't they

[iron belfry]

@flat pilot the origin is what? the same as the target of the line? both start and end are set to the mouse. also, the execute line from the origin is not plugged to anything

@grim cargo well, when you right click the folder in the content browser, there is a thing called fix up redirectors

@grim cargo kinda mystical, i dont know exactly how it works, but it removes the ghosts in the physical folders when moving or deleting files the content browser

[flat pilot]

I'm just starting out with bp's, am I missing something ? why would I plug the execute line on anything ?

[iron belfry]

@flat pilot if the function is not plugged it wont execute. why dont you try instead to use a function that doesnt have an execute line

[iron belfry]

@flat pilot https://answers.unrealengine.com/questions/541325/how-to-draw-a-line-in-the-hud.html

Try to hook it up to Tick as I think what it is doing it only draw it for one frame so you might not notice it..

[iron belfry]

@flat pilot well, i dont know how to use the HUD either

[frosty bloom]

I strongly suggest you read some beginner tutorials & Docs

[vale osprey]

@tropic pilot GangOfBeast have characters with physics locomotion, that's not something you can teach in a tutorial. Google for physics based locomotion, there are plenty of different articles with different ideas.

maybe there is a plugin for Unity that implements some of that, would explain recent surge of those kind of games

[tropic pilot]

actualy i found a tutorial of this BY Epic Games on youtube 😛 so there is tutorials on it

[iron belfry]

to stream or not to stream? that is the question?

@flat pilot https://www.youtube.com/watch?v=l0U8ydqMm30

@flat pilot i see the draw line should be called within the hud blueprint

hud blueprint doesn't accept mouse imput
If I understand it well, you can't draw things on the hud after it's been loaded

[south ridge]

But if you really think that, you're kinda stupid

It's not about "like"

[plush yew]

but i just dont like it

[south ridge]

Nobody "likes" source control

[plush yew]

exactly my point

[south ridge]

People don't use it because they like it dude

[plush yew]

no one likes it

Also power outage corruptions are something that Microsoft VSS was prone to back in 90's and early 2000's. Ever since then you don't really care about that

[plush yew]

You can't say though that source control is fun to work with

[cloud cobalt]

Anyway, every time someone loses work, that's always the one answer. GET SOURCE CONTROL YESTERDAY.

[plush yew]

My favorite source control is probably perforce

but i still feel like it has some problems

[south ridge]

https://www.arqbackup.com/ <-- also get this or a similar app. Heck, you can do similar stuff for free if you don't wanna pay

[cloud cobalt]

Perforce is free for small teams, keep a local Perforce server and voila

It's still better than nothing

[south ridge]

Also copying files to a second HDD in your computer DOES NOT COUNT AS PROPER BACKUP

[plush yew]

bitch yes it does

[south ridge]

No it doesn't

A proper backup must be to a different computer off-site

You do both local and remote backups. Local for speed, remote because that's the one that actually matters

[cloud cobalt]

We're not even talking about backups here. Source control is incredibly more than just a backup for every hour of work you've ever done in your life

Which is, kind of cool

you know.

[south ridge]

Well, he should start with backups at least since he hates source control so much

Your local backup is there simply to recover files faster if local backup didn't get messed up by whatever event that happened

[floral heart]

He should just stream everything he does on youtube so he can refer to it later.

[mint raptor]

So from max to unreal the blueprint asset made has the components all in the wrong place even though the groupings are correct

what can I do to fix this?

[cloud cobalt]

@plush yew Look, we're not going to force you. But source control for software is like floor plans for buildings. You could technically build a skyscraper without one, but you really don't want any living thing inside it 😃

[plush yew]

i think its great for teams

but not for individuals

[vale osprey]

huh

[surreal viper]

if you like loosing all your work then your approach is perfect

[frank escarp]

well, i even use source control in personal prototypes

[surreal viper]

life without source control is like playing dark souls with perma death

[south ridge]

I mean

[plush yew]

Yo someone link me

to a perforce host

[south ridge]

After you lose a considerable proportion of your work and give up on your project, you'll learn why you need those things

[plush yew]

i doont feel like paying for it

i mean

setting it up

i can pay for it

[vale osprey]

yeah I go commit while I eat 😄

[cloud cobalt]

Just have it on your own computer @plush yew . It won't be a backup, but when you accidentally change something, you'll have the full history for it in excruciating detail.

Free Perforce server, done

And copy the repo to an external drive once a week

[south ridge]

https://www.visualsvn.com/server/ If you want to use SVN, this one's pretty good

Also btw

A single copy of data isn't a proper backup either, it has to be based on days, weeks etc

Because your corrupted data may accidently propagate into backups

[merry gazelle]

Guys I have an animation question, I've asked in the correct topic but I would really appreciate what I assume would be a quick awnser. Basically I have a cine camera in level sequencer and want to capture all anims, light fx, etc as previewed in game/simulation. Currently I can only figure out how to add/configure individual assets one by one

[vale osprey]

but re-doing months of work makes you code so much cleaner!

[south ridge]

Few days ago I lost a 10 GB texture source file haha

It was same-day work though, so I re-did it quick

Since it was same-day work, it didn't end up in source control or backups yet

(the reason was a bug in how photoshop saves files, the way it saves them is incorrect)

Photoshop writes new file, waits for write operation to complete, then deletes old one, renames the new file

Which is incorrect because write operation completes sooner than data reaches disk

I had a driver failure in the short 2 minute window while data was still dumping to disk 😄

[surreal viper]

any idea how could I pass a value to an animation blueprint before any update?
it's in a spawner, but there is just no way I could find to pass the value from spawner to spawned actor before the animation BP gets his first update

even if I pass the parameter to the actor with the spawn node using the metadata specifier expose on spawn it's too late

only way I can see now is to create a child BP which has that value setup properly but that is way too stupid 😦

[south ridge]

I think you can do a delayed spawn?

You can create actor, but only spawn it in world after you've set all parameters

[vale osprey]

as long as you get reference to your skeletal mesh you can set value

[south ridge]

So you set your parameters in actor which get picked up by animation BP etc

Or directly set animation BP before it starts executing

[surreal viper]

delayed spawn sounds awesome, I'll take a look

[south ridge]

But point is, you can spawn things with a delay and I'm pretty sure that is exposed to BP

[vale osprey]

OnBeginPlay of actor with that skeletal mesh should work fine

[surreal viper]

nope

onbeginplay is way too late

[south ridge]

It's same as normal spawn, but you have to call a function to finalize spawn after you set all parameters

[surreal viper]

even preinitcomponent is too late

if the spawn isn't delayed, I just tried those

[vale osprey]

well, to be honest, what AnimBP can do that it needs value before OnBeginPlay?

[surreal viper]

I have a glitch in the first frame otherwise

I set the spawn animation this way

[south ridge]

I know the kinda issue you're having

I solved it by doing a child BP kinda thing 😄

There is a weird one frame delay in animbp in my experience

I don't know why or how to fix it, but it seemed to me that animBP's always worked with one frame delay

[vale osprey]

yeah, it's updated after physics or something, one frame constant lag

[surreal viper]

can't really find this delayed spawn tho

[south ridge]

It's annoying since I have suspension I'm trying to animate

But it's between two actors

[surreal viper]

not in bp at least

[south ridge]

It seems to work OK for suspension in actor A attached to actor A, but not for suspension in actor A attached to actor B (e.g. animating in a way that puts it into a 'slot' in actor B)

It's not a big deal for our game, other than a minor visual weirdness

Where when suspension springs around heavily, you can see the 'plug' part drifting a little out of the 'socket' part

[vale osprey]

yeah had the same issue with tank

I don't remember if I've fixed that

using local space helped to not have 2 frames lag thoe 😄

[south ridge]

I also am thinking about adding a little bit of extrapolation

@vale osprey yeah, I can't do that, I have to attach a suspension element to another actor

Since bogey & train are two different actors in our game

For modularity purposes (and because it's the only natural solution :D)

[vale osprey]

I have it attached to another component

from what I understand, the issue there is what should be updated when?

physics is one frame in front, if I understand correctly

[surreal viper]

@south ridge any idea how should I search for this delayed spawn? I failed to find any info on it

hmm I have a crazy idea
I could just push the parameter to a stack before spawn, and read that in the anim BP

yeah that's what I'll do

it's an FName, I might as well just store it in a static variable in c++ or something

[vale osprey]

@south ridge found the fix: one thing is this:

and on top of that this:

wheel physics position is updated forcefully from within sub-step, so it's always correct on Post-Physics

but might not work in your case as it's in different actor

you could call update of suspnesion from Post-Physics of parent actor, but that woudn't be too modular

[south ridge]

It's not a big issue

[vale osprey]

I was just curious myself 😄

[south ridge]

99.99% of the time the suspension is relatively at rest

You have to really fuck up the train to see those suspensions moving

And I'm gonna add a linear limit to the distance joints anyway, because you shouldn't be able to pull off the bogeys too much from the train

[vale osprey]

doesn't it lag when it just moves fast?

[south ridge]

Yep

I mean

It's actor-relative animation

So actors velocity doesn't matter

Only relative velocity between two actors

[vale osprey]

Hmm, we might be talking about different things then

I mean generic transform lag on skeletal mesh. Like if you have a vehicle chassis static mesh component and skeletal mesh wheels

The faster the vehicle moves the larger becomes gap where wheels are and where they should be

If I understand update logic correctly, it happens because skeletal mesh is updated pre-physics and static post-physics

But that doesn’t make too much sense as post-physics is kind of pre-physics for next frame

perhaps it's not the skeletal mesh itself but a root bone issue, not sure

[south ridge]

It might be the same sorta issue

I just have a different setup so I see it from different kinda point of view

[gleaming shore]

Is it possible to import a new character model but use the same rigging/movement as the default one?

[south ridge]

Yes

[cursive dirge]

that's pretty much point of retargeting

[tropic pilot]

why do this happen

[south ridge]

@tropic pilot happens due to invalid/mismatched rotations of the bones between that skeleton and reference skeleton (or animations)

Rotations/translations

E,g, rest pose bone transforms are not the same as for which the animations were designed

E.g. animations were done for a T-pose, but your characters skeleton rests in a different pose. Retargeting can fix this (requires adjusting transforms to match up the two poses)

anyone know any good perforce hosting

that doesnt cost $50 a month

lmao

[south ridge]

Yes

Localhost 😛

[plush yew]

Nah

thats not safe

what if my hdd fails

then its pointless

i need something external

[south ridge]

I mean, you probably should be using backups for that

Source control isn't backups

But at least you're moving in sorta right direction

[tropic pilot]

@south ridge doesn't look wrong to me!

[plush yew]

bro i know what it is

lol

i even have stuff on github

i just dont like using it

because its a bitch

to use

[south ridge]

No, you don't like using it because you don't understand why it exists

I mean

It's a preference thing, nobody likes doing some things, but those things are there because everyone hates losing data more

[floral heart]

And then there's people like me, who use git and rebase everything.

[south ridge]

@tropic pilot can you compare it against the skeleton for which animations were made

Have you retargetted those animations onto this skeleton etc?

[tropic pilot]

i just imported the character and it came with skeleton, physics assets and all

what im trying to achive is to make the arm's (left and right) just flop arround as you run arround with the character

and when i simulate inside the Physics assets the arms are perfect.. but when i test play the arm is fucked up :S

[coarse cradle]

cel shading is not easy lol

[errant lintel]

how can I use the WINDOWED command from : https://docs.unrealengine.com/latest/INT/Programming/Basics/CommandLineArguments/

I tried "-game -log WINDOWED" at the end of my command

but my game start in fullscreen mode sadly

I also tried -WINDOWED

[silver crown]

That's a batch I use to launch my build in windowed mode @errant lintel

[errant lintel]

ok thanks 😄

I set a resolution to have a border and it's works perfectly:
-ResX=1280 -ResY=960 -WINDOWED
thanks again @silver crown

[unique ocean]

Been working on UE4 for about a year but still a newbie

how do I import a package to a specific folder?

Trying to keep things clean
