hey guys

ancient otter
is there a material node that inverts something?
so if the input is 1 then its -1
exotic thicket
multiply by -1
ancient otter
makes sense
rancid lynx
also known as 1- node
ancient otter
OneMinus of 0.4 is 0.6
it says that in the wiki
im trash at math but im pretty sure the oposite of 0.4 is -0.4
rancid lynx
oh wow. 1- works in materials, but i cant find it in blueprints.
it might be a material only option
ancient otter
its for materials
fading walrus
Does anyone know anything about creating an AI in UE 4? ._.
rancid lynx
i just manually blueprint "add impulse" to my "dumb ai"
fading walrus
i use blueprint as well
rancid lynx
"look at target" and "add impulse" but thats a terrible way to do it probably.
exotic thicket
There is a decent behavior tree quick start guide in the documentation which seems to go into basic AI
rancid lynx
those tutorials AI are much much smarter than mine also.
fading walrus
well when my AI collides with other AI's or objects it breaks
ancient otter
can you help me real quick?
rancid lynx
do behavior trees all require navmesh ? i hate the idea of spamming navmesh all over the place
ancient otter
so i have this
displacement add in -10 does something and its the opposite of 10 wich is the value i have
but then if i just put the multiply to the add it does nothing
im confused
ancient otter
what do you mean
rancid lynx
make a new empty 1- node. it will have a left input
dont use the multiply
im really not sure. but that worked for me.
rancid lynx
may not work for you. probably may
your 1- looks different than mine
i didnt use a multiply node. thats why 1- does.
this 1- node inverts the fresnal direction
ancient otter
oh yeah ok
rancid lynx
thats the limits of what i know. i barely made it that far.
ancient otter
thanks
fading walrus
could someone help with my AI?
ancient otter
im pretty sure there must be some videos on youtube
fading walrus
as far as i seen, none that help with them colliding ._.
tawdry heath
hey guys how would I fix this teleporting thing
plush yew
theres a long live in unreal yt channel about ui
watch it
depends on how ure rotating ur character
halcyon flame
does anyone know much about the replay system? I want to make ghosts for a racing game and I'm wondering if they can leverage the built in replay functionality
tough marsh
@tawdry heath idk why you think its teleporting? All I see is the character rotating really fast. Try slowing down your rotation when you want to turn around
tawdry heath
ye where would I do that I'm new so I don't know where I should be looking I was just following tutorials
tough marsh
look in your character blueprint for your input keys whatever you are using to make you turn around
then show me
tough marsh
no thats stuff in the blendspace or anim bp i was just asking about the inputs you use to turn with
bitter iris
@tawdry heath if you want an easy way to show ppl your BPs use https://blueprintue.com/ (as theyre quite blurry like)
tawdry heath
well if you on pc you can click on "Open Original"
tough marsh
like w,a,s,d inputs in your character bp
tawdry heath
there's this
normal burrow
Issa use VectorLengthXY instead of VectorLengthSquared
also Issa, is your blend space the character walking forward in different directions?
normal burrow
character is facing the same direction in each yeah?
tawdry heath
normal burrow
its just foot placement differences?
tawdry heath
are you asking if the character stays in place?
yes he is facing the same direction
normal burrow
with Walk_Left is the caracter facing forward and moving left?
halcyon flame
@normal burrow sorry if I'm bothering you and you already saw this, but do you know if the replay system could be used concurrently with gameplay, ie ghosts in a racing game?
normal burrow
No idea unfortunately dingoman
halcyon flame
@normal burrow thanks, no worries
tawdry heath
@rotund scroll https://blueprintue.com/blueprint/8p_0c2re/
halcyon flame
if anyone knows of any rare resources on the replay system I'd love to see them. there's oddly not much about it.
tawdry heath
@normal burrow yes my character is facing forward and moving left and is in place
normal burrow
ArmRotation is what
tawdry heath
Does interpolation time have to do with anything?
normal burrow
as far as i can see its rotating something to face the direction your inputting. I can't tell if its in the anim graph or not
tawdry heath
I think what is happening is that it's using the "forward" animation and when I rotate direction it rotates the forward instead of using left or right...
normal burrow
I think so too, thats why i was asking about the facing direction
it could be the pawn is rotating to face the movement direction or the animation. its unclear to me
tawdry heath
here's the animation blueprint https://blueprintue.com/blueprint/g2alyuf_/

@rotund scroll well for starters, there's this in the details pane when you click class settings
rotund scroll
yeah but is it free
halcyon flame
@rotund scroll what?
halcyon flame
@rotund scroll I don't think it will corrupt things. certain functionality will be changed depending on what classes you're switching between and you'll just need to compile and work through the errors/warnings
maybe back up your project if you're really worried

Hey guys, Unreal was crashing a lot, I read one of the ways to fix it, It'is update drivers and update the unreal. I downloaded the 4.24 and when I'm copying my project to the new one i got this ->

thin tendon
Does anybody know of any games that let you choose toon shading as an option that can be toggled? I just added this as a feature to my game. I can't find any other games that have done it. I was hoping to research and see what hurdles this feature might throw my way.
thin tendon
So a lot of games use a toon stylised cell shader. To maker it look more like a cartoon.
brave widget
You mean cell shading?
thin tendon
thats the one
rotund scroll
usually it's part of the art direction
so they don't change it because it doesn't fit
if you had said outlines it'd be a different question I think
thin tendon
Yeah. I added it as something that can be toggled. To let player's decide how they want it to look
So you can have either a more realistic look or a cartoon look
But I can't find any other games that did it this way. So I can research potential hurdles
rotund scroll
the main hurdle is that you have to make stuff look good twice
and yeah generally art direction is pretty unique and not something that is subject to choice in games
not counting the fact that you'd have to do everything twice
thin tendon
okay. So each time I make something new. I just have to make sure it looks good both ways.
rotund scroll
pretty much
you might also realize that you game eventually will suffer from a split identity, but that depends on other factors too
if you're looking to build atmosphere art direction is just one part of that
thin tendon
Well the idea behind the game is I'm trying to give as much control as possible to the player's. They can also pick the colour scheme for the GUI themselves.
brave widget
Its an interesting idea, but like Cranz said, I think it'd suffer an identity crisis. There is a reason McDonalds doesn't let the franchise choose their colors ๐
thin tendon
Yeah it makes perfect sense. Your right I may have to find a way to encourage it.
The idea behind it is people usually respond well the more they can control and customise stuff
rotund scroll
it has to be something worthwhile
if it's trivial nobody cares
if it hurts the game people will complain
if they have too many options people will complain
better to make a good linear and unique experience than to try to cater to everyone
thin tendon
I see what you are saying. Maybe I should focus more on the other stuff.
normal burrow
what are McDonalds colors?

rancid lynx
how do i control how sharp the blur between 2 different layers while painting terrains?
this 1meter fade between layers is a little excessive X_x
abstract relic
Adjust the weight value of the brush
rancid lynx
thats 1 option, what about inside material editor options ?
something about clamp ?
ill double check brush options.
brush options are not nearly sharp enough
normal burrow
May need to up resolution rob
abstract relic
Not even brush falloff?
rancid lynx
i solved it with clamps last year, and it looked really nice and sharp
falloff zero isnt even close
latent moth
a quick question: a standard practice to attach a gun is to set up a socket in the hand_r and then IK your hand_l (and thumb or other fingers).
However: what do you do when you need to manage multiple weapons? do you create a socket attached to hand_r for every single weapon? Would it make sense to have the weapon with the same character bones and attach them with something like
abstract relic
Well next question would be if you are using weight blending or alpha blending
latent moth
well for 1 gun it is
sure, that's what i mean with "attach a socket in the hand_r": create a socket under the skeleton bone, sorry if a little criptic
but I mean: what if you have 50 weapons
how to you adjust hand_r position, how do you attach the gun
cloud cobalt
Each weapon should have its sockets
latent moth
so 50 sockets?
cloud cobalt
The sockets should be on the gun
normal burrow
Or just enter a transform on the blueprint somewhere. Just was saying parenting to a fk bone is not something games fo
latent moth
I did mean a socket attached to hand_r, sorry if criptic
my question is on how do you handle multiple weapons: multiple sockets?
rancid lynx
the fade is much sharper between sand and grass, layer 1, the fade is pretty terrible between grass and dirt. last year i found a solution between layers using some clamp. but i cant remember how or what youtube video.
normal burrow
hand_r would be forward kinematic and jittery attachment point with interpolation. There be multiple ways
latent moth
this video of fortnite animators seem to refer to the practice https://www.youtube.com/watch?v=Oe7fYS9qxmk
normal burrow
Socket works as suggested by stranger
latent moth
so you reverse, attach a mesh to a gun and use a gun socket instead?
normal burrow
Really both would work, reverse socket sounds nicer though
cloud cobalt
You asked about standard. Standard is that the gun is attached to the player, but the hands use IK to match the socket on the gun.
So each gun just has 2-3 sockets for hands, finger etc and the hands mesh matches that
latent moth
ok, so x 50 if you have 50 weapons
i'm trying to understand if there's a way to use only 1 socket for hand_r position and adjust it somehow with variables, just like we do with hand_l
normal burrow
What type of blending rob?
rancid lynx
well sorry. i really barely understand.
ill search youtube some more. its out there.
rancid lynx
make a manual offset for each weapon actor ?
latent moth
so you attach hand_r to the gun, correct? right now i'm attaching the GUN to the hand_r child
rancid lynx
thats how i do my tools
cloud cobalt
No, I did not say that @latent moth . ATtach the gun to the hand, without using any socket, and then use IK in the anim blueprint for the hands to reach for the gun's sockets.
rancid lynx
i dont efven use sockets, i just use "attach to component nodes" or attach to actor. but im probably doing it wrong.

Is there a way of re-aranging bindings/action mappings, it would be easier if I could drag them to arrange them by alphabetic order or controller type, i.e. Xbox controller, Mouse, VR. At the moment they are just ordered as I input them and seem to not be moveable.

so niagara is a "new" particle system? if im looking into using particles in my project, i should use niagara instead of cascade?
lament saddle
Niagara's a big leap over Cascade, but I've also found it to be unstable in both the editor and packaging (though YMMV). So it depends how much you value stability.
Epic is starting to test Niagara in Fortnite so hopefully it'll become more stable soon... https://www.unrealengine.com/en-US/tech-blog/how-epic-is-integrating-niagara-into-fortnite
regal mulch
Theoretically you can use either, cause they sort of must keep Cascade in the loop for projects that are using it already.
However there are probably a lot of advantages of using Niagara, as it should offer more features.
And it's not so stable yet, as Renzu notes.
I haven't touched it myself though, so just repeating what I read in the past.
I would probably go with Niagara though, cause it's theoretically better to take the new feature that is supposed to replace the old one.
grave nebula
Niagara has significant pipeline commitment, as compared to cascade, where you are free to jump in and create an effect.
regal mulch
Would probably help to explain significant pipeline commitment
As in, what does that entail?
exotic thicket
Oh that's what niagara is :P
I will have to give that a spin because my entire project is experimental and probably never finished anyway and it seems interesting lol
regal mulch
Might be good to move this to #niagara . I just noticed we are in #ue4-general :D
lament saddle
Again YMMV, but if your goal is to "learn Unreal" then go with Niagara. If your plan is to continually migrate your project to the current version of Unreal then it might be okay to roll the dice on Niagara if you're not shipping any time soon.
If you're planning on shipping on UE4.24 or earlier then stick with Cascade... unless you're okay with Niagara bugs
Cascade is fine for simple emitters but Niagara lets you do interesting things with arbitrary data
fierce tulip
though there is something to be said about using cascade and the massive amount of tutorials it has, to learn and understand other aspects of making vfx. while different, a lot of it is knowledge that can be shared between the two.
lament saddle
Yeah Cascade is easier to learn for sure b/c of documentation. It would've taken me ages to figure out Niagara if I didn't already know Cascade...

I'm looking for a way to expose to BP a cpp parent's OnComponentBeginOverlap event (not delegate) so it can be used internally instead of externally. how would I go about this?

You can use BlueprintImplementableEvent for functions that BPs can override, but have no C++ implementation.
And BlueprintNativeEvent for functions that BPs can override AND have a C++ implementation.

How to change text in widgets?
vale spade

vale spade
yeah, wait short ill boot the editor up ๐
vale spade
ooh, so via that
in your widget blueprint, add a custom event, name it 'set display box text' or whatever, and under the event inputs add a 'Text' variable
Drag in a reference to your text box, then pull off that pin and use the Set Text node, make sure it's the set (text) node not set tooltip text :)
Then from whichever other actor, either use get all widgets of class, and obviously use your widget type, get the first item from that array, or store a reference to it in the actor, then call your custom event (set display box text) on that, and plug in the text from the actor's own text variable ๐

why not fix on next hotfix for 4.24.2
brave gate
there was changed in the header, and they usually don't put that to "hotfixes"
@vale spade @drowsy turtle avoid calling UI from gameplay classes, especially doing iteration like "get all widgets of class", gameplay actors shouldn't know about existence of things like HUD as given UI can changed/destroyed/hidden, etc.
- create delegate (event dispatcher in BP) in the class where value is changed
- in the widget get reference to this gameplay class (i.e. player controller) once and cache it, bind to the event dispatcher from your gameplay class
uncut vigil
@frail sail it will be fixed on the hotfix, but there's also a bug that crashes the engine which will be fixed in 4.25

Okay so I have an input called "Interaction" bound to R
I have a blueprint that starts with overlap, how would I make it so that "If overlapping > if pressing R > do thing"
brave widget
I don't know if this is the best way, but you can set a separate bool on each (on overlap and press R) and then compare them both for true
serene quiver
Like the blueprint has a hitbox so I want it to be like "If the player is inside the hitbox and holding R do thing"

ye what chipmunk said. then
have your interaction on off set a bool to true false
check said bool in the overlap

there is axis lookup

you could take a second look if you want chipmunk
but i didn't see anything for the actions our game uses beyond events
you'd make a bool and set it with R on off yeah krabs
then check said bool in overlaps
brave widget
What about "Gate" ?
I haven't used it but looks like it could work
Overlap will "open" the gate and pressing R can "enter" it?
I assume thats how it works
serene quiver
I have this but it's not working so I'm doing something wrong

Woah, thanks!
timid jacinth
how do i actually get the node @brave widget
serene quiver
Would've never figured that out on my own haha
timid jacinth
nvm got it
brave widget
that works, I had to check cause I was having a brain fart moment ๐
normal burrow
that basically treats R press as fire all overlap events, but when held on a new overlap, also do that
you set Current Overlap to nothing at the end there as to allow the thing to gc
(don't want to hold a reference, a local variable would be better really but event graph as it is)
serene quiver
Where do I get the blue set nodes? If I search set I get a lot of results
normal burrow
you have to make a new variable of type Actor
normal burrow
then you set it like i do
serene quiver
Like this?
normal burrow
Down hard to know what is going on there.
is there a line trace involved?
and krabs, no
variable type should be actor
timid jacinth
Its just an aimoffset
serene quiver
Ah, gotcha
normal burrow
i've not used aimoffset really down, would probably look at what you are feeding it though
brave widget
Krabs, on your Event BeginActorOverlap, right click on "Other Actor" and select promote to variable, then you can pull it out of "My Blueprint" to set it and it will be the correct type
normal burrow
Yeah chipmunk has better advice there, thats much easier
yeah Down i mean
look at the actual values pumped to the node
set the preview actor to your character while playing
add a watch in the anim graph

zero for interp speed means instant right?

The problem is only on the client
normal burrow
the local client character or remote?
timid jacinth
The second player
Not the host
The host is fine
Everyone connected to the host is glitchy
normal burrow
its likely that its interpolating the angles
but
RInterpTo
you should try removing this completely.
InterpSpeed 0 means instant i think
normal burrow
do you ever use roll in that networked angle?
timid jacinth
not at all

believe its the same issue
normal burrow
the aimoffset is likely fine
timid jacinth
one mistake could have lead to this
normal burrow
its the network interpolation
i say that with like 70 percent confidence because i'm not real knowledgable about networking in ue4
timid jacinth
me neither haha
normal burrow
the key is that if it happens on the second client to the host
that makes me think its relying on some angle that isn't being properly interpolated

Does anyone know how to make an AI fly with blueprints. I've got an AI following the player and it keeps getting stuck on blocks around the map
exotic cave
I have tried two different .OBJ exporters with painted vertex colors for a grass mesh now, and UE is stripping the vertex colors every time ๐ข
rotund scroll
@exotic cave yeah I doubt you can import vertex colors, use the in editor vertex coloring instead perhaps?
normal burrow
yeah calicoastreplay, obj works
exotic cave
@rotund scroll : Can UE do that? I was not under the impression I could vertex paint in UE and then save the mesh
normal burrow
you have to tell it not to strip the colors though
rotund scroll
sure, shift +2 in editor, or pick the vertex paint mode
exotic cave
@normal burrow : How?
@rotund scroll : But that works per-actor and if it's resaved as a mesh, the vertex colors are not
This is for a grass mesh for landscape material grass. UE can't use an actor, it has to go right to the mesh.
How can I tell the importer not to strip the colors? ๐ฆ
normal burrow
it looks like it was broken in a few versions cali
what version are you using now?
exotic cave
I'm on 4.23
normal burrow
and how are you expecting to see the vertex color?
are you reading them in a material?
exotic cave
It's for the grass wind.
Top two vertices are painted red, bottom are black, there's a multiply in the material for the vertex offset
The vertex colors could be getting attached to a material, I'm not sure ๐ฆ
It's just a simple quad. I was under the impression this is a pretty standard way to do this, but creating and importing the grass mesh properly has been a nightmare.
normal burrow
a second uv channel may be easier than vertex color if its not working
@exotic cave
brave gate
@rotund scroll yes
- player camera manager is the best place for scripting camera i.e. managing camera modifiers, registering custom actors/stuff that can influence camera behaviour, blending between gameplay and cinematic camera
- if you're using several player controllers, switching/blending camera could be handled in camera manager
normal burrow
don't ignore and then you have to reimport after
Replace is the right answer i think

exotic cave
Thanks for the help though, I appreciate it
normal burrow
rotund scroll
@brave gate so it's more about camera data than camera logic? I'm trying to figure out where the best place for placing camera logic is. e.g. focus/view rotate to
brave gate
camera manager then as this the class actually calculating camera transform
exotic cave
Where are you seeing that setting?
brave gate
usually you could override UpdateViewTargetInternal() to implement your own camera rotation
brave widget
@normal burrow @cosmic panther Are both of you on the West Coast in the US by chance?
rotund scroll
@brave gate so help me understand how the camera manager relates to the camera that is in the player character for instance
normal burrow
north coast
brave gate
camera component in the player character (or anywhere else) it's just like definition only: component moving the actor + parameters
rotund scroll
close enough
brave widget
Ok, I'm having net troubles to, wasn't sure if you were near me and maybe our issues were related
cosmic panther
@brave widget East
brave gate
active camera is managed by player camera manager
brave widget
Must be net issues nationwide ๐ค
normal burrow
trick with discord issues is to assume everyone else has them
its usually the case
brave gate
setting active camera through player controller is just for convenience and player character is a typical place to put camera component
rotund scroll
@brave gate so in terms of transform I use the transform component in the player camera manager to set rotation, location etc.?
cosmic panther
Yea there is
brave gate
but player character doesn't update camera ๐
rotund scroll

second question, setting a timer for a function that has a signature other than void?

exotic cave
mhmmm

sure
brave gate
yes, technically active camera object is used to get data and fill "view target" with that data, but you could do whatever you want with "active camera" - i.e. just read the current player camera as start or end of blend
and script your own "blend from player view to the place I force player to see"
exotic cave
rotund scroll
@brave gate yeah there doesn't seem to be a built in way of doing this? at least not in BP

@exotic cave its not got any vertex colorsIt's probably exporting it into the material then, I appreciate you taking a look
normal burrow
the one quad there at the bottom
exotic cave
Blender is such a s***show
normal burrow
well vertex color would be a a 4 part vertex
1/1/1/1
instead of 1/1/1
for what it is worth
obj is a shit show
exotic cave
There's a .mtl file it exports as well, I am quite sure it's getting dumped into that instead
exotic cave
I honestly wonder if I could literally just add it to the file myself for now
normal burrow
its not out of realm of possibility that blender things it belongs there though and that it'd be right still
brave gate
@rotund scroll there's only SetViewTargetWithBlend() exposed to the player controller or putting custom logic in BlueprintUpdateCamera in blueprinted PlayerCameraManager - second can be used to animate camera programatically as it overrides default camera update
normal burrow
you could probably lol
exotic cave
OH NOTEPAD, MY ONLY FRIEND
rotund scroll
@brave gate set view target with blend changes camera though, not view
exotic cave
Don't there need to be four?
normal burrow
that is how you would introduce two colors
then you just /1 or /2
to the verts on the face (f)
exotic cave
One per vertex?
normal burrow
v for example declares a vertex position
vt is a uv
vn is a normal
so when you see f
this means face
brave gate
@rotund scroll Camera Modifiers are actually exposed to blueprints too, so you can use it for custom scripts, i.e. this you'd use to blend from player camera to using any custom transfrom (start of cinematic or focus point)
normal burrow
its saying first position, first uv, first normal 1/1/1
exotic cave
This is great information, you are fantastic
rotund scroll
@brave gate ah hold on, with BlueprintUpdateCamera, does that tick automatically? can I get it to do my dirty business of interpolation?
brave gate
yes ๐
rotund scroll
shoot that's great stuff
brave gate
it does take this calculation on camera update
rotund scroll
right but I'd have to use something like RInterp yes?
brave gate
exactly ๐
rotund scroll
cool that does save me doing the same setup
I see that it requires a target, though if there is no target, what does it default to?
brave gate
major limitation of unreal is that we can have only one active camera - no support to just pass to 2 transforms and ask engine to work on both of them, but override camera update and camera modifiers allows for a lot
probably the view of player controller - as this always exists
rotund scroll
I have no issue with just one camera
brave gate
not 100% sure, always using camera in pawn in my games by default ๐
exotic cave
@normal burrow : Still didn't work but I think I've figured out why
I actually think .obj itself literally has no vertex color support
rotund scroll
but anyway some great knowledge and advice all around, appreciate it! I might ping you if I get stuck, if that's ok?
exotic cave
Only the .mtl file actually supports them
rotund scroll
@brave gate
normal burrow
it does cali but my recollection of vp being vertex parameter and its use may be wrong
exotic cave
vp seems to be "parameter space vertices"
normal burrow
oh so, those v lines, you put four floats after the position to define the color
v 1220.094482 -572.500000 177.713943 0.984314 0.764706 1.000000

vp was wrong yeah
brave gate
@rotund scroll if you really stuck or willing to save money for a good whiskey ๐ ๐ ๐

@normal burrow : That doesn't work either, I really think it has to go in the .mtl, maybe I need to import both at the same time

Hi all, Vehicle Multiplayer Replication - after testing for a very long time now, with numerous vehicle/physic types from Sedan/Advanced/Blueman - The client always seems very jerky on Lan/Internet/Steam.
Does anybody have any pointers or suggestions please
calm widget
I've done that multiple times.
normal burrow
how
calm widget
Blender exports vertex colors just fine, i've since replaced them with textures, used them for blocking stuff out. But there should be no problem with it?
normal burrow
fbx?
calm widget
Yes
normal burrow
hmm
exotic cave
Yeah, I'm working on trying to get it in FBX instead, can't be done in OBJ is what we found
Because OBJ puts its vertex colors into a separate .MTL file UE can't read
calm widget
Yes obj doesn't export vertex colors, but i don't see why you'd have issues with fbx?
exotic cave
Give me a moment, it may be a question of settings. FBX def has a different default scale than OBJ
calm widget
Scale in blender for UE4 export should be set to centimeters with a 0.01 scale
exotic cave
I appreciate that
normal burrow
You can also just set the scene metric to centimeters
and avoid the 0.01
i think that is a semi new thing though
exotic cave
FINALLY
Okay, thank you both so much. I had to import as an FBX, then set that setting to Replace, then reimport the mesh
calm widget
Proably, i've got mine set to meters sorry, scale 0.01. Centimeters would do fine
calm widget
Not sure about newer version of blender, but as far as i know its fbx support has always been quite bad, something about licensing i guess. But it does the job with a bit of tweaking
normal burrow
yeah, its honestly confusing how blender gets away with fbx
if you plan on using it in a game, you need to use the autodesk sdk afaik

tawdry heath
how the hell does a timer work
brave gate
@rotund scroll so it does work, your calculations set camera to the floor ๐
rotund scroll
@brave gate yeah because I can't set the camera target
the function uses that as a parameter, but I have no way of passing it
nor does it seem like it's running every frame
exotic cave
@normal burrow , @calm widget : You gorgeous creatures, you've saved my world today
brave gate
@tawdry heath https://docs.unrealengine.com/en-US/Gameplay/HowTo/UseTimers/Blueprints/index.html

brave gate
@rotund scroll so grab camera component yourself from the player character - I didn't use blueprint update for years
in code actually I get camera from pawn manually
rotund scroll
right but if I then have to manipulate that inside the camera manager it's something of a faff right
brave gate
maybe your interpolation make update "so slow", idk, it' called every frame, otherwise would be useless
rotund scroll
pulling it all the way through the controller just to let the camera manager use it
brave gate
it's assigned through player controller because of multiplayer-ready architecture
so the server could set it clients
rotund scroll
ok I got it working, but again I cannot pass the target so it is useless to me
because it will only ever look at my player character
brave gate
confusing, but actual update happens in PlayerCameraManager class
rotund scroll
which I suppose is my camera target
but then I need to use my player character as a dynamic object that can move the camera around but still maintain that the camera is looking at the right actor
brave gate
to be honest, I don't know what/where you can pass ๐
yes, so you need to get your player character and "actor to focus on" in your camera manager blueprint and operate on it anyway you want
update is performed every frame
rotund scroll
but I can't even if I do that since I have no way of passing the parameters to the UpdateCamera function
brave gate
yes, but you have entire blueprint to use, and cache actors as class variables ๐
and you could still call GetPlayerPawn() in this function, although obviously you don't have do it every frame
rotund scroll
seems like a hacky solution
rotund scroll
then why isn't it possible to pass the parameter to the UpdateCamera?
brave gate
it has view target saved with the reference to the "actor with camera" + parameters
I don't know, man
maybe they assume you can do whatever you want in this function
rotund scroll
and the camera default location isn't the same as the camera the player character has
so idk
seems really wonky
reading this, it seems like UpdateCamera is only used if you want some non standard camera use that pertains to the player. e.g. if you want to create your own version of a springarm. it doesn't seem to be made to handle advanced functionality or camera focus: https://forums.unrealengine.com/development-discussion/blueprint-visual-scripting/1497649-how-do-i-set-up-the-player-camera-manager
... which again is weird, because it seems like the class has little to no purpose then
brave gate
@rotund scroll works for me in the last few games ๐
although.... in one of "focus to actor" implementation of first person camera I set desired target rotation as controller rotation inside of player controller (SetControlRotation method) every frame - as there camera follows controller rotation
and I use override in camera manager to update interpolation, which axis to update, speed and apply additional modifiers (like something else change FOV or speed of camera rotation)
have no idea even if you have first person or third person camera - I don't remember implementation details for third person
--
in another project I use camera manager and camera modifiers to blend from player camera to sequencer camera - with option to update blend along with the player movement, and there's no code in player controller/pawn for that
although I understand this entire setup is confusing as camera can be controlled in many ways, i.e. automatically follow player controller or be attached to the spring component and then player partially control its rotation which is not strictly tied to the pawn rotation
in my first UE4 game I did most of camera calculation in this blueprint update, but maybe it was for adding procedural noise/head bob
so yeah, perhaps camera manager is not that important your implementation too ๐
but you started from asking about advantages of using camera manager, so I maybe got lured there ๐
rotund scroll
right but we can agree then that updatecamera is not what I'm looking for?
brave gate
have no idea what your's design is ๐
rotund scroll
focus on another actor, other than the player character
otherwise do whatever the camera does normally
brave gate
if you'd blend controller rotation in your player controller, than update in camera's manager has little or nothing to do
brave gate
if you'd use camera modifier, than basically you add modifier to camera manager, and camera modifier class does to job for you
rotund scroll
I find I get motion blur from the set control rotation
perhaps the trick is a camera modifier then?
brave gate
the math would the same in both, I guess
didn't had "issues" with motion blur in my cases, maybe turned off or interpolation basically smoothed out and I forgot ๐
it's nighttime for me here, so I can just drop a bit of simple code
CurrentBlendTime = FMath::Max(CurrentBlendTime + GetWorld()->GetDeltaSeconds(), FocusBlendTime);
const float TimePercent = CurrentBlendTime / FocusBlendTime;
float BlendAlpha = 0.f;
switch (BlendFunc)
{
case VTBlend_Linear:
BlendAlpha = FMath::Lerp(0.0f, 1.0f, TimePercent);
break;
case VTBlend_Cubic:
BlendAlpha = FMath::CubicInterp(0.0f, 0.0f, 1.0f, 0.0f, TimePercent);
break;
case VTBlend_EaseIn:
BlendAlpha = FMath::Lerp(0.0f, 1.0f, FMath::Pow(TimePercent, BlendExp));
break;
case VTBlend_EaseOut:
BlendAlpha = FMath::Lerp(0.0f, 1.0f, FMath::Pow(TimePercent, 1.0f / BlendExp));
break;
case VTBlend_EaseInOut:
BlendAlpha = FMath::InterpEaseInOut(0.0f, 1.0f, TimePercent, BlendExp);
break;
}
SetControlRotation(UKismetMathLibrary::RLerp(CameraRotation, DesiredRotation, BlendAlpha, true));
that simple copy-paste from camera code to update rotation
rotund scroll
seems like BlueprintModifyCamera in camera modifier has something interesting, as its target is "Camera focus other actor"
brave gate
if (PawnCamera.IsValid())
{
PawnCamera.Get()->SetRelativeRotation(FRotator(GetOwningPlayerController()->GetControlRotation().Pitch, 0.0f, 0.0f));
OutVT.POV.Location = FMath::VInterpTo(OutVT.POV.Location, PawnCamera.Get()->GetComponentLocation(), LocationDeltaTime, LocationInterpSpeed);
OutVT.POV.Rotation = FMath::RInterpTo(OutVT.POV.Rotation, PawnCamera.Get()->GetComponentRotation(), RotationDeltaTime, RotationInterpSpeed);
}
and just calling interpolation, parameters tweaked and works fine for me...
rotund scroll
I mean I've done the logic before with setcontrolrotation
I just want to try other stuff to ensure that it's the only option at this point
hence why I'm trying the camera modifier as well
which tbh doesn't seem promising
because again there is no functionality to set targets as parameters
brave gate
it's just another mechanism to call camera... ekhem... modification
rotund scroll
well yeah, but there's no exposition to modify the camera
brave gate
you have GetViewTarget() in camera modifier
rotund scroll
aside from the override function
brave gate
there rest is up to
rotund scroll
which again, cannot be called in BP
so
it looks like there's no reason these classes exist in BP
brave gate
there's really not much more in code ๐
BlueprintModifyCamera() allows you progress update
math is yours
rotund scroll
the math isn't the issue
the issue is that I can't tell the camera to use another actor for instance
brave gate
there's ProcessViewRotation() and UpdateAlpha(), yeah, that looks useful ๐
rotund scroll
I can't in the camera manager and I can't in the camera modifiers
yeah I don't have those
brave gate
I don't understand it, how you want to "tell camera to use another actor"? you get 2 transforms and blend them...
plush yew
Hi Folks - I am working on various materials for my arch viz project -- I have noticed that some of my materials import into UE4 just fine, others dont -- is there a chart that shows the proper suffixes to put on the different textures, so that UE4 knows what they are?
rotund scroll
@brave gate I might as well not use the camera manager or modifier classes then
I can blend those same transforms outside of that
that's kind of my point
there is no affordance in using the camera manager
unless you really want manual control over everything your camera does to your player character
anything else is off limits
I mean christ even the camera location and rotation of the manager are set to 0
brave gate
you can also do it level blueprint, sure ;)
all entire game in player controller :P
it also about separating code between classes that actually uses them
yes, in Unreal you either let camera manager just follow your camera component by setting engine flag or fully scripting
rotund scroll
yeah but since set control rotation is part of player controller and not player camera manager
brave gate
as "focus to actor" is fully custom script
rotund scroll
what's the point of pushing all those values to the camera manager only to have the manager use the player controller's set control rotation?
and the fact that the camera manager's camera is just some random camera instead of being the same as the camera in the player character is just additional weirdness
like why
brave gate
well, if you don't need rotating player capsule or updating position for traces coming from the controller point of view, you can skip controller rotation
but not every game uses this!
you could have third person game or RTS with totally different setup ๐
rotund scroll
of course, but why is it then tauted as best practice?
brave gate
also in another FPP game I don't override controller rotation, I just use camera modifiers
you asked, if there are any advantages of using camera manager
I replied ๐
rotund scroll
right but the answer was misleading because in reality the answer is, "for the most part, not really"
brave gate
probably too focused on replying "use camera manager, it's good" ๐
no, the proper answer is "it depends", as always in programming and gamedev ๐
maybe I forgot about pointing that this time too ๐
rotund scroll
well of course it depends, but the way it was tauted was as best practice thing to use for all camera related needs
when in reality it provides no support for camera
brave gate
and yeah, I keep forgetting that some obvious stuff isn't actually exposed to blueprints, like 1 or 2 methods ๐
rotund scroll
it really seems like those classes were not meant to be extended in BP
brave gate
what I mean all camera updates are actually performed by camera manager or modifiers, forgot how important is controller rotation often ๐
rotund scroll
so I'm wondering why that is even possible at this point
brave gate
but you truly doesn't need much more there.... more important here while you're working on camera is that you can read engine classes and better understand underlying mechanisms
rotund scroll
I do feel I need more functionality to justify the class in BP tbh
brave gate
hehe, no wonder
rotund scroll
as well as the decisions to keep the manager camera different than the player character camera for instance
brave gate
camera managment itself in UE4 is rough ๐
rotund scroll
I want it to make sense, but it doesn't
brave gate
well, it because you can have many camera targets in the game
rotund scroll
that doesn't really matter does it?
brave gate
pawn, vehicle with pawn, cinematic camera, focus camera, eagle camera, switching to security camera
it does
rotund scroll
you could solve that all with set view target with blend, a function that you can even only call outside the player camera manager
brave gate
it would incredibly stupid to put camera managment into pawn while you're using camera from different target
but that because of multiplayer architecture ๐
you change camera though the server which doesn't has renderer
and than change it's pushed to clients - which can update its cameras now
rotund scroll
even with all those cameras, you could easily have that as a function of the controller
brave gate
also pawn can be despawned anytime, so you can't have camera code there
but you can switch controller too
rotund scroll
I mean that's basically the way that it is now, because the set view target with blend function isn't callable inside the player manager
if you switch controller you switch camera manager anyway
since they are coupled
so idk what the point of that is
brave gate
but you can have a different player controller for Simulate in editor ๐
and you can use spectator player controller to call regular camera manager ๐
rotund scroll
that doesn't invalidate anything I said
brave gate
or use camera manager in Simulate without custom player controller
no
but if you write an engine code, makes no sense to put camera update in the player controller
rotund scroll
ok but can you at least concede there is no need for it in BP then?
brave gate
it wouldn't support all use casses
no
because theses classes are useful
I shipped game with blueprint camera manager and it was fine for me
rotund scroll
well you can still use it, you just can't extend it
brave gate
like with everything in Blueprints really ๐
rotund scroll
idk it seems very much a very niche class
mossy nymph
why wouldn't you be able to extend the PlayerCameraManager in BP?
rotund scroll
I'm trying to understand why you would
it offers no extra functionality at BP level
mossy nymph
PC can pick the PlayerCameraManagerClass
rotund scroll
so I guess... some camera modifiers?
mossy nymph
has some BlueprintEvents
rotund scroll
only for when it becomes view target
mossy nymph
so you can write custom logic in it
rotund scroll
I wish it had more tbh
worn granite
brave gate
that's the Unreal way, no "blueprint camera manager limitation"
