The problem is that each time I compile the drawer behaves in a different way !! without changing any of the initial settings !!
Has anyone experienced something like this ? Am I doing something wrong ?

does anyone know why linetrace from camera suddenly offsets after teleporting?
tired tree
offsets how?
fresh wharf
@tired tree the linetrace is always in the middle of my vision, but after i teleport straight forward on the x-axis, the linetrace is only in the middle of my vision when i look straight forward or backward, if i move at another yaw axis than 0 or 180 degrees, the linetrace offsets to either the left or right, depending on what side i'm looking towards
i hope that kind of explains it

@sturdy coral that steamVR motion smoothing, willing to bet anything that the depth buffer support they added recently but which isn't really in use yet will be used to bring it up to snuff with ASW 2.0 at some point

https://www.youtube.com/watch?v=Y5yMYK0hRgU&feature=youtu.be&t=943 anyone got an idea on how to make this "head through the wall effect" and maybe some other example of games that do this?
fresh wharf
@sonic lake i feel like your blueprint for stereoscopic pictures doesn't display them properly, do you have any additional settings turned on/off to make them display properly with your bp setup?
grand chasm
@tired tree I am trying to figure out if your plugin adds events in unreal for the tracker pogo pins or if I have to set on as a controller? I would prefer to keep my standard controllers plus use the tracker if posdible. It seems the situation has been evolving lately. Do you have any advice? Thanks!
tired tree
i don't add anything specific for them no, i leave the input binding to Epic
i removed my special tracker class when they merged everything into a tracked device base class
its been awhile since I played with them, very niche uses for something generic like my framework
so no idea on the current input setup with them
sonic lake
@fresh wharf Define "properly". Take into account that stereo images are taken with a fixed IPD. The Go has its own fixed IPD and so do your eyes. 😉 They may all be slightly different, so having a perfect match is very difficult.
sturdy coral
@tired tree they don't use it at all for overlapping with overlays?
fresh wharf
@sonic lake true, but when im using a constant of 0.5 instead of the custom node, the picture is waaay sharper, just has a really clear seam
tired tree
@sturdy coral its not currently used in ue4 unless it changes in 4.21 and I missed it
and since its new I doubt the motion smoothing is using it
sturdy coral
right I mean in steamvr though
tired tree
but yeah I would expect it to effect the stereo layers when passed in
sturdy coral
do they make use of it?
ah ok
but yeah they should definitely use that to augment ASW if possible
not sure how well it would work with temporal upsampling, since depth can be a lot lower res than final scene color

Guys, I have a UMG (smartphone app kinda thing) attached to my VR Hands. that user can interact and use the apps inside it all in UMG. but found out it's so performance heavy. I see this "Slate UI / Slate 3D" in my GPU profiler sometimes hit 5ms ! any tips how to optimize it maybe ?!
real needle
@dusky moon What are you displaying on it?
You can turn down the update rate on the widget component, but animations won't look great if you do
Have you tested in packaged buildm
Because slate can be the editor itself
tired tree
@dusky moon in editor or outside of it? because the entire editor is slate
pearl tangle
if you are using the default data binding type stuff then it will be updating everything on tick which is what kills things. Use events to push variables instead
dusky moon
@real needle yeah I actually set the update rate to 0.08 and it helped a lot.
my UMG is full of layers and contents. most of them are collapsed and become visible on-demand. but still is heavy.
and yeah I was mainly talking about Slate 3D and it shows in package build too.
@pearl tangle Ah that I didn't try. good tip
frigid kite
Speaking of UMG, am I correct when I say that the stereo widget on the vive is still rendered on top of everything?
tired tree
currently yes, but they did add depth buffer support recently
frigid kite
Hmm, so how does one even make use of it?
The regular widget component is incredibly blurry
sturdy coral
@frigid kite have you tried forward rendering without TAA?
frigid kite
The project is cross platform to standalone, I gotta keep it in deferred
sturdy coral
@frigid kite standalone?
sturdy coral
ah
frigid kite
and actually, the fps was quite a bit worse in forward
So it's easier to stick to deferred
sturdy coral
you can lower the jitter size for temporal while the UI is up or while it is taking up X amount of screen space and get less texture blur but more aliasing elsewhere
and lower the history contribution
frigid kite
alright, that's a good idea
and hopefully the newly added depth buffer support for the stereo widget will come into play soon
sturdy coral
is it translucent or solid?
frigid kite
solid
sturdy coral
you can also render a translucent quad over it and set responsive AA in the translucent material
that will do the same as lowering history contributions, but just over the UI
but at low resolutions you will see more of the subpixel camera jitter TAA uses in it
frigid kite
alright, good idea - I didn't know about the responsive aa flag
Another question, for a different project: I have a setup where the player's hands are sweeping towards the motion controllers, so they collide with the world
This works fine generally, but when climbing using the vr expansion plugin, the sweeping seems to be ignored and I can just shove my free hand through the wall by moving myself around with the climbing hand
the sweeping is done as a component in the Character, through GetWorld()->SweepSingleByChannel() in the component's tick
so the component does a sweep towards the motion controller's location using a SweepSingleByChannel() check, not by moving an actual collider around, since only the root component of an actor can do sweeping checks
Actually, I just checked and the sweep is also not triggering when walking using the regular motion input, only when moving the controllers around while standing still
Could it be a ticking order issue? Or is it something else entirely?
real needle
I'll try turning the sweeping hands into separate actors tonight, maybe that'll work
dusty iron
My UI is flickering in VR.. Any SOLUTION.?
tired tree
@frigid kite @real needle you have two accounts with the same name...... Anyway, the climbing is moving the actual character in the movement component, it sounds like your sweeping is tick ordering prior to the movement components actions so they aren't picking up the new offset.
set them to either tick in a later grouping than "Pre_Physics" or set a tick prereq to the character movement component so that they sweep off of the final movement
the motion controllers already tick prereq the movement component so if you tick prereq them they will naturally order correctly (should have been post the controllers in the first place)
if you don't need frame perfect physics collisions of the hands with simulating objects then having them tick During_Physics is likely best
real needle
I've tried moving them to post physics, to no avail
I believe I'm already prereqing the controllers in the sweeping components as well, though it might be a scene component attached to the controllers instead, I'll check it out this evening
tired tree
there isn't a reason it wouldn't work then
unless you are pulling the wrong original location
you have to remember that moving the character also moves the hands
so unless you are going off of your original loc and sweeping and then setting pos it won't have the intended effect
you should be able to set absolute position on them though
mighty carbon
real needle
So it should definitely also work as components then, @tired tree ?
tired tree
set loc and rot on your hand meshes to Absolute
that way they don't follow their parent when it moves
you'll need to set initial position once though
at the start / spawn
real needle
Ah interesting, that's a flag I wasn't aware of
I've just sent a client a VR build, tomorrow his company is gonna be at a fair showing off their products with a Vive, and with the VR expansion plugin 😉

you can try turning off ASW while recording, as I believe it uses your card's encoder hardware

Hi, how I can check FPS in the VR template?
Coz if I try console command with "stat FPS" I cannot see FPS in the headset.
I have 4.20.3 engine version.
frigid kite
Dima, it's best to use the tools from steam / oculus to check HMD performance
they give you an in-hmd overlay
frigid kite
steam vr compositor > settings > developer > check "show gpu performance graph"
you will also have an fps counter in the settings menu, in the bottom left
which will tell you when reprojection kicks in
Ugh, I'm struggling with the simplest thing, I can't get overlap events to fire when my pawn enters a triggerbox
both are set to generate overlap events, the trigger is WorldStatic and ignores everything except Pawn which it overlaps, and the pawn is set to Pawn and ignores everything except WorldStatic, which it blocks
and yet no overlaps are being fired
the pawn is collision enabled, the trigger is query only
runic cedar
@frigid kite Oh thanks i find it and add in the headset, but i cannot see fps i see MS and Hz
runic cedar
If you need collision you maybe need to add static mesh and add colision
in the pawn
frigid kite
yeah the pawn has a capsule collider as root
runic cedar
i added
for overlapping. I remember once doing the following.
Yes 11 ms of less but i think that is fps like in show fps, but it's okay
I did not even know what it was like to check in the steamVR
dusky moon
On your trigger volume, OnEventBeginOverlap you cast to your pawn if it's valid and it should trigger if the collision setup is fine
frigid kite
The problem is that ActorBeginOverlap is not even called
It does work with another pawn though, but I can't see why
runic cedar
Yes i tried also and get the same not overlapping :/
frigid kite
Hmm
The pawn that's not overlapping is the vr exp plugin pawn, but in principle it's also just a regular capsule collider moving around

Hello there !
I'm wondering here about "3D Stereo Spread" value.

Hey all, getting a strange issue with VR players spectating after travel.
In the main menu, the player can look off in a random direction just before travel (up for example), and then during travel they could end up looking forward, which then post travel, ends up with their camera/pawn tilted the same as pre-travel (absolute) so when they look forward with their HMD, their camera's forward direction it up in the air like it was pre-travel.
This is for players joining a game WaitingToStart
They are supposed to be spawning with a spectator pawn (setup like a standard VR pawn). The host is fine, they have the proper pawn, but the clients either are using the pawn, or more likely are not using the pawn and are in a really weird spectating position...

Is there a simple way to detect if a HMD is on someones head? as in pause a game when you take the HMD off and restart when you put it back on?
frigid kite
There's a HMDWornState node
however, at least with the vive, it only sets itself to not worn if the hmd has been still for some time
sly elk
similarly we have a toggle in wrench between vr and screen mode. At some point this stopped working well and like 50% of the time whne I launch the game it doesn't find the headset
gleaming river
@frigid kite is that very similar to the GetIsHMDWorn in the VRExpansion functions?
frigid kite
I wasn't aware of that one, I don't know if that one works more reliably
gleaming river
I shall have a play and report back if one works better than the other 😄
they both return the same options so i presume they are very similar if not the same
frigid kite
ishmdworn returns a bool, no?
tired tree
@gleaming river my function is a holdover from before the official one actually worked
the official one was broken / missing for a long time
I actually need to deprecate mine now that things have changed
regardless, on vive it behaves like that because it doesn't have an actual sensor like rift and WMR
so it has to assume on no motion for a period oftime
frigid kite
So what does the little sensor on the vive do?
tired tree
its a proximity sensor
but its returned with motion influence unless you poll it like a button
which ue4 doesn't do
frigid kite
So if unreal polled it differently, it should have the same functionality as the rift
tired tree
not really true "doesn't have one" I should say, as it "behaves differently"
VREvent_TrackedDeviceUserInteractionEnded - The user hasn't triggered the proximity sensor in long enough that the system believes the HMD is no longer being worn. The timeout here is currently 10 seconds, but this could change.
they are working off of that event

I need to put up a pull request, but the WMR steamvr driver recently broke support

sturdy coral
@frigid kite @dusky moon I'm using knuckles with WMR now btw, it works pretty well
to align the tracking systems you only have to adjust position and yaw
sturdy coral
nah I haven't touched that
they recently put out an update that improved clarity through steamvr a ton
they were sampling the render buffer an extra time before or something and adding blur
I would like to see how perf differs between native and steamvr, I'm not sure their native stuff even has ASW though, I think it is tied to their steamvr driver
@tired tree ^
gloomy holly
i assume that baked and static lights are no problem though
tired tree
@sturdy coral how would it be tied to steamVR? SteamVR specifically disables interleaving since WMR uses its own
sturdy coral
@tired tree I think steamvr's compositor disables interleaving but WMR's steamvr driver implements ASW
wicked oak
@mighty carbon okay what the fuck kind of magic is that
the only way i see it working is through pre-rendered 3d backgrounds/billboards/etc
cryengine is MAD overkill on everything, its renderer is extremelly high cost
mighty carbon
that's why I put "o.O" after my post @wicked oak 😃
sly elk
@gloomy holly My game has a dynamic lighting and shadows and runs without issue. It just depends on your content and how you set things up.
gloomy holly
thanks Alec, i'm hitting a brick here while trying to create a rather big scene (due to client requirements)
sly elk
If its a big world shadows are going to be expensive since you will need more than 1 cascade
gloomy holly
i'm pending HLODs though, so maybe that could fixm y issues
what do you mean by cascade? (sorry for being ignorant on that regard)
sly elk
You could just do 1 cascade and fade out character shadows after like 20 feet
Look up how cascading shadow maps work
Unreal has a bunch of other shadow solutions for characters. I think capsule shadows work in VR
gloomy holly
thanks a lot
that keyword will help me quite a lot
from the top of your head, how would you optimize a big map?

@real needle 2d UE gets directly written to the viewport in 2d as a rect, scaled and positioned according to GetOrthoProjection
I think only the Oculus plugin implements GetOrthoProjection correctly
it is better to use in-world UI via UWidgetComponent
or use stereo layers, which lets the compositor construct a plane in 3d for your UI and can have more clarity
but doesn't integrate with scene depth on steamvr right now (I think it does with the oculus plugin)
sturdy coral
@real needle I believe the 2d ortho mode means it will get reprojected by the compositor and move the wrong way in a subtle way, there are ways to do head-locked ui with those stereo layers that will be correct with the compositor

as long as meshes had the same material in Doom 3, they were batched
I was under impression UE4 does the same thing
tired tree
ue4 solution to it is baked mesh merging
and instanced meshes
for the bandwidth reduction
frigid kite
Unity's batching system is also not perfect
I believe lightmapping breaks it, because it then uses different textures (if the objcets are on different atlases at least)
And for dynamic batching, only very low vertex count meshes are supported
Still, it's very nice if it works, I was so surprised when I learned that Unreal didn't automatically batch static objects using the same mesh and material
And that "instanced materials" are really just a poorly chosen name
Did you see the new FPS demo, and the new GPU particle system video Unity released yesterday?
They're finally catching up, the new stuff looks good
But Unreal's framework and interface just make it so much nicer to work with still

Can it integrate easily with Unreal?
Same price, damn
I know it's not the same thing, but it would be cool to do, specially with controls like move
mighty carbon
@tacit shore how is it the same price ? 399 Rift and 499 Vive (and it doesn't come with headphones)

Both of them are 7k BRL here.

get Oculus Go maybe ?
tacit shore
I have a VR-like thing here, it's a Shinecon V4
those that require a good phone to use
That's why I wanted to use UE4 with Adreno 505(my phone's GPU)
mighty carbon
Go doesn't need any phone and is like the top mobile VR right now
tacit shore
Same price as PSVR here
mighty carbon
or you could make a cool prototype using UE4, register for Oculus Start program, show it to Oculus and they maybe would send you free Go/Rift
tacit shore
Nice idea
Would love to get a Rift
Even though I would like to use my Shinecon with my phone, if UE4 were compatible with its GPU
This one
It's kinda cool
I hoped the engine would work, but I read somewhere it wasn't compatible with Adreno 505
tacit shore
looked up the Oculus Start, you have to have published a VR project before getting on the program
cosmic shoal
Funny we just got a mail from oculus that our Rift is on the way (grade B refurbished, what ever that means)
a hoodie, a glass of wiskey and other random stuff
We do have a vr app published on the iphone app store tho.
So we will now have a Vive, 2 WMR headsets and an a Rift.
wicked oak
@cosmic shoal my case is a lot more hilarious
they had a mistake, so when they sent me Touch devkits, they sent me 2 packs
at the time, they were sending 2 oculus +2 sets of touch to people
but due to the mistake, they sent me 4 oculus + touch
cosmic shoal
heh
wicked oak
and now on the oculus start
they did the same
so now i have 3 oculus go, and 6 oculus + touch
and 2 hoodies

just to complete the collection
are they collecting dust or did you get rid of them?

Why both hands look like right hand 🙈, anyone experienced such thing
frigid kite
I'm looking at my hands right now, and now that you mention it, it does look like I have two right hands
I might need to see a doctor about this
fossil sky
Ok come back to me please, I need my left hand
mighty carbon
Maybe you need to multiply scale of left hand mesh on one of the axes by -1 ?
tired tree
waaaay better to have two seperate models
sonic lake
@fossil sky This is what the VR template does anyway. There is only a right hand and the left hand is just a mirrored version of it. When BP_MotionController is spawned, the left instance is mirrored.
tired tree
that -1 axis change screws over bounds calculations on skeletal meshes really badly
it might not matter at first, but have seen a lot of people run into wanting to use the hand mesh for something and the messed up bounds and calculations breaking things
fossil sky
I tried to scale the Z axis to -1 but it did not work
I have a show room, and it does not make sense that the customer will see two right hands hehe, they will run away
and I am using this to trigger a widget, but it is disabling the grab function, When I remove it the grab function works fine
sonic lake
@fossil sky Can you show the hand mesh? Maybe the Z axis is not the right one to mirror.
fossil sky
That's It
mighty carbon
sonic lake
@fossil sky What I meant is that your hand mesh may require mirroring around a different axis than Z, depending on its orientation. Did you try with X and Y as well?
fossil sky
I tried them all, Nothing has happened
tired tree
then it sounds like either that node isn't running or you are looking at the wrong mesh
because something would have happened
fossil sky
I tried to give it a positive value like 2, and this amplified the size of the hand
but I couldn't reverse the direction of the hand

If you can get more investment money take it. Especially if they are looking to completely dominate the space. Gotta get to the point where nobody else can even enter that market. All that money helps.
Plus it gives you runway to operate at a loss if needed to undercut and put competitors out of business.

Damn, guys
wicked oak
@granite jacinth from the 80.lv leaked roadmap
they have 2 planned upgrades to the rendering
the first is to handle gpu drawing better, that is a straight perf upgrade (and allows funky shit like automated instancing)
the second is render graph
render graph would re-structure the rendering of unreal into a series of passes
each pass with input and output targets
the idea is that the graph system makes sure to connect stuff together in an effective way
to use memory really well
for example, no more "gbuffer 1/2/3/4" bullshit
the system deals with that
the programmer just asks for "scene color" texture in their pass
it also allows async compute passes
but, the main thing
it would allow plugin rendering upgrades
imagine VXGI being a plugin, not an engine upgrade
and it simplifies rendering code MASSIVELY
sturdy coral
@mighty carbon not if they raise money in a normal investment round, issuing equity normally dilutes existing investors
but sometimes it can be done as a different class of shares that don't have any voting rights
sage gulch
or something silly like holding shares in a fund, splitting them, and selling a portion
wicked oak
uhm there is very active development about the render graph in github

subtle raft
I'll ask this here too Dumb question, how should I make Stereo Layer UMG templates? Templates I can use to customize text and colors in world without having to make a unique BP for each type of interactable
glossy agate
@subtle raft you can just use ‘set text’ node tied to any text variable.
subtle raft
in the Widget BP right? How would I do that through the Stereo BP though
glossy agate
You have to create a reference for the widget in the the bp so you can pass in the request
subtle raft
@glossy agate Like this?
glossy agate
Yeah that should get you in the right direction. Should be able to call events on the widget through that
subtle raft
I would want to set the class widget right? but I don't think that's possible
glossy agate
Should already be set if you added which one you wanted to that widget component
subtle raft
I'm wanting to be able to use this one BP and swap out the widget class it uses
per world instance
or just set the UMG text per-instance
I was able to set the text, but I think the UMG happens last so it always set it back to whatever the text is set in the UMG Widget
like if I bound an event to the BPs construction script and sent that over to the Widget Blueprint it would change the text but immediately change it back
maybe Im just trying to do something dumb
should I just make different BPs for each UI object
glossy agate
You can just make a bunch of children off the master and just spawn the one you want when it’s needed.

Anyway to get comboboxes working on 3d Widgets? Editor is fine but standalone they are not working. Tried disabling fast path, but still not working.
mighty carbon
sturdy coral
@daring pasture how did you disable widget fast path, paste code
works for me and fixes the combobox problem
I set it in code with PC->ConsoleCommand(TEXT("Slate.EnableFastWidgetPath 0"));, I can't remember but setting it in ini might not be enough
I think it might enable itself again when not GIsEditor
if you don't do it on the command some time after startup, I think I do it on first tick
yeah I mention there ^ it sets itself again if you don't do it after startup
daring pasture
Thanks, I'll try running it in command and see if that works. Was just doing it in ini so that is probably the issue.
daring pasture
Setting it to run on first tick fixed it, thank you!
subtle raft
anyone have any idea why glancing angles with a Widget Interaction isn't activating a widget component's OnClicked?
sturdy coral
@subtle raft are you using cylinder geometry on the component?
subtle raft
no
subtle raft
it's a stereo widget
plane
it works at like 30 degree angles
but any more than that it doesn't click
but it still hovers
sturdy coral
you are using ue4 or a plugin?
subtle raft
ue4
sturdy coral
what is a stereo widget?
sturdy coral
hmm, can't think of anything that would be causing it
sturdy coral
add a breakpoint and then compare all the calls for click at the two different angles
subtle raft
the thing is the character won't be able to hit the button at these angles anyways, I just wanted ot figure it out if I ever did need to know
I've already spent like 4 hours trying to fix it :\
sturdy coral
I would add a breakpoint to UWidgetInteractionComponent::PressPointerKey and see what happens in there
write down the call chain that happens afterwards in notepad and compare between the two angles
subtle raft
how do I do that
sturdy coral
in visual studio you just click in the left margin of the line where you want the breakpoint
sturdy coral
you won't be able to see the internals of what it is doing wrong in BP
KeyNone would be wrong though
turn on debug draw too on the interaction component if you haven't tried that, that may help diagnose a bit
@subtle raft I'm not sure what the "parabola" distortion mentioned here is, and why they only apply it to Y and not X:
void UWidgetComponent::GetLocalHitLocation(FVector WorldHitLocation, FVector2D& OutLocalWidgetHitLocation) const
{
ensureMsgf(GeometryMode == EWidgetGeometryMode::Plane, TEXT("Method does not support non-planar widgets."));
// Find the hit location on the component
FVector ComponentHitLocation = GetComponentTransform().InverseTransformPosition(WorldHitLocation);
// Convert the 3D position of component space, into the 2D equivalent
OutLocalWidgetHitLocation = FVector2D(-ComponentHitLocation.Y, -ComponentHitLocation.Z);
// Offset the position by the pivot to get the position in widget space.
OutLocalWidgetHitLocation.X += CurrentDrawSize.X * Pivot.X;
OutLocalWidgetHitLocation.Y += CurrentDrawSize.Y * Pivot.Y;
// Apply the parabola distortion
FVector2D NormalizedLocation = OutLocalWidgetHitLocation / CurrentDrawSize;
OutLocalWidgetHitLocation.Y = CurrentDrawSize.Y * NormalizedLocation.Y;
}```hmm Im trying to add a box collision to just get it working, but Im doing somethign wrong
where do I even put this code

Date: Tue May 26 15:32:32 2015 -0400
UMG - Adding a parabolic distortion option for widget components.
[CL 2565502 by Nick Darnell in Main branch]```in the WidgetInteractionComponent Class?
does that mean it creates a sphere for the collision?
sturdy coral
ah the parabola distortion seems to be something you apply to the material itself.. then the hit trace ends up reading a value that comes from the material instance... somewhat convoluted
subtle raft
whats a parabola in this instance mean
sturdy coral
seems to be some sort of distortion effect in the shader, probably parallax
seems similar to the cylinder stuff
it actually doesn't read the value from the parameter to use, it reads it to see if it has changed against a uproperty version and needs to set it
it is strange though, in his commit WidgetComponent has a ParabolaDistortion UPROPERTY in the header, but in 4.20 it is gone.
sturdy coral
@eternal nexus ^ seems like the change might not have been fully backed out for UWidgetComponent::ParabolaDistortion?
subtle raft
sturdy coral
I don't know if that is an actual bug though or that normalized thing ends up being right, but looks like some remenants of ParabolaDistortion are there but not everything
subtle raft
so here's what I'm working with
in this Im basically constantly clicking
and when it clicks it should be moving back and coming forward everytime
and as you can see the onhover always works
sturdy coral
is this in vr or with the mouse?
subtle raft
and actually this is an issue because even head on the button sometiems doesnt work
this is FOR VR, but atm I'm jsut using my mouse
I have the stereo layer disabled
sturdy coral
k, I've just noticed it being off one time with the mouse when attaching an interactor to the camera, it was skewed from the crosshair somehow
so you see this regardless of the stereo layer thing you are using
even if you turn off the stereo layer in VR and show the widgetcomponent instead?
subtle raft
I havent tested it with the stereo layer enabled, but the stereolayer has no collision
right now it's bascially just set to display the widget as a widgetcomponent and not projected into the rendertarget
just for testing and so I dont have to use my HMD constantly
but when it's run for real the widget is hidden with a material and sent to the stereolayer but still interactable
but stereolayers only show in the HMD so I set that up
but I'll gut the thing up and just have the elements I need in it
if I just make a version with just the widget component in it it still doesn't click right
sturdy coral
it looks like that parabola stuff is wrong scales both X and Y by currentdrawsize, then divides by it for both components, (removed parabola math not present in 4.20), then multiplies by it again but only for Y instead of for X and Y
subtle raft
should I copy/paste the 4.19 code in
but that would prolly break other stuff
as a cylinder
this is what you were talking about before with the cylinder right
sturdy coral
hmm 4.19 wouldn't be enough, that commit came may 2015
I'm not sure when it was backed out
sturdy coral
I'm trying to remember the exact cylinder problem
subtle raft
Im gonna try this in 4.19
sturdy coral
cylinder is separate from this parabola stuff
looks like what I have in my code for where cylinder goes wrong is this:
// NOTE: with cylinder widgets, hit.Distance is wrong. UWidgetComponent adjusts Hit.ImpactPoint
// after first tracing against the plane but fails to update Hit.Distance, so we recompute from
// TraceStart and ImpactPoint.
[...]
FVector NewWorldScale = MC_##HAND##_Laser->GetComponentScale(); \
NewWorldScale.X = FMath::Max(FVector::Dist(Hit.TraceStart, Hit.ImpactPoint), .0001f); \
so I think it still goes to the right place for interacting with the widget, but it returns the wrong distance, which I was using to render a laser pointer
wicked oak
at the end i wont be able to push the DWVR 120 fps update
fukc
damn QA reviews and patching system
gotta have to wait till im setup properly in amsterdam and can bring the devkit there
subtle raft
I think I figured it out
I failed to make notice of the "Press Pointer Key" implementation
and the onclick I did make was set to the widgetcomponent and not for the widgetBP
@sturdy coral thanks for the help though
https://www.brightdevelopers.com/creating-interactive-huds-virtual-reality-unreal-engine-4/ I was following this guide and even had the browser scrolled to the "Press Pointer Key" part this whole time but never read it
sturdy coral
@subtle raft why was it angle dependent?
subtle raft
I have no idea
about that still
but it was just because I was implementing the interaction wrong
you're not meant to click on widgetcomponents to fire an event
and thats why the hover worked but not the click
the hover was firing in the widgetBP and my onclicked was firing and implemented in the widgetcomponent
what a relief though
sturdy coral
@subtle raft not sure what you mean "you're not meant to click on widgetcomponents"?
sturdy coral
oh
subtle raft
it apparently just doesn't work right
at least not with the Widget Interaction component
which is kinda funny since by name you'd think that would work 🤷

@sturdy coral just finished the skeletal replication btw, had it on the back burner
around 64 bytes avg a send

@sturdy coral per hand
I likely will end up self compressing it anyway, due to the decompression function not being available on other platforms for cross platform
sturdy coral
@tired tree was that with position too or just the hand animation itself?
tired tree
included mesh deformation
so if they unchecked that option and I am self compressing I could just drop all locations out
the compressed buffer comes with some artifacts too, so i am still on the local end getting the full list and using it locally

sturdy coral
not sure, there was an alternative to tcp that did
if it is message based instead of stream based you can get away with a lot more
tired tree
yeah i remember reading about the concept before
sturdy coral
they still target some platforms like web and stuff I guess where it just would never be able to peek ahead because it goes over TCP
unless you send over multiple sockets
tired tree
well the sending cost isn't all "that" high for steams skeletal transforms when you rate limit it and lerp between updates
10 htz is likely fine
sturdy coral
yeah you could also make exceptions for the rate limit for fast changes
tired tree
i have gesture detection
could merge that in
on a new gesture send an instant update
ect
sturdy coral
@tired tree since they derive the pose from curl floats, a few cap sense bools, and some trigger/joystick/touchpad axises, it feels like they should just decimate those and reconstruct pose from them
since it is an opaque compression/decompression thing, they could still do the generic thing for leap motion or whatever
I guess every client would ahve to know about every driver for other drivers to be on a fair playing field
tired tree
yeah
which is the issue i am having with rifts and not running the steamvr runtime

What's the best way to reduce drawcalls for mobile VR? Let's say I have multiple materials on one static mesh. Is there an "easy" way to merge them?
Bake Materials and Merge Actor supposedly are able to do this, but both give horrendous output (especially when materials are different types, i.e. one opaque, one translucent)
Otherwise, is the best (and maybe only) solution to just export all materials and create an Atlas and reimport?

Hello, How can I create (or enable the red line laser pointer, if it is already built in ), So I can use it instead of the hand itself to trigger/overlap trigger boxes.... etc ?
frigid kite
It's all just regular blueprint work, really
Attach a collider to the motion controller, execute a line trace every tick, place the collider at the trace's hit point
Check if the collider is overlapping anything or listen to its overlap event, and handle your game logic there
The laser is just a cilinder that's stretched to the length of the line trace
frigid kite
You don't actually need the collider component, you could also just do overlap tests directly

@solar loom if (FApp::UseVRFocus() && !FApp::HasVRFocus())
{
return; // do not proceed if the app uses VR focus but doesn't have it
}
// Poll game device states and send new events
XInput->SendControllerEvents();
in PollGameDeviceState in the Application sub class

@tired tree Super! Thanks! I'll check it out.

pretty sure only WMR and Rift uses that setting though
solar loom
So that would mean other HMD's would send controller events?

i didn't look too deeply into it, but SteamVR isn't setting that var

@tired tree You are a strong developer)

@tired tree and for anyone who wants to know, as far as I can see in the plugins only Oculus is using the FApp::SetUseVRFocus(true) . Unfortunately I don't see a way to override that.

in 4.21 WMR native does as well

Ah ok, thanks for the heads up. I'm still working with 4.20

btw, I am wondering if there is still a spinning ring present when loading UE4 app on Go. It was there in 4.16 and it was essential for Gear VR app submission process as UE4 couldn't fulfill 4 sec time frame on initial run.

I'll load one of my prototypes up real quick
oops, guess I left it running for a few days
BTW, there's this new stat UNIT measurements

But it doesn't always happen in 4.21

Super useful, need to check if that's in non-mobile vr as well
@mighty carbon No ring, took around 5 Mississippis
(but this is a dev build, so ship build could...should be faster)

hmm.. I guess Go isn't Gear VR.. I don't remember how long it took for my project to load, but on Gear VR it took 10 sec for the engine itself to load.

@jaunty shell Glad you found the solution! :D

To those of you who use the VRExpansionPlugin:
The VRExpansionPlugin wiki says of its VRCharracterActor pawn: "By default it blocks sticking the players heads through solid geometry". Would someone point to where in the source code this functionality is achieved?

That will be ok if they still support using the cameras at the same time too
though I wish the cameras would be 100% wireless
if not it is just WMR pretty much, with four cameras instead of two so larger volume to track hand in but you'll still get dropouts

does the oculus driver screw up the screenshot framebuffer size for anyone?

Hello, I used this BP to draw a laser beam coming out of the right hand, And It is working fine, Thing is that I want this laser to overlap the collision boxes and when it is overlapping enable trigger input:(
I have been stuck for a while, and I am totally newbie so please, simplify the answer 🙈
PS: The project is a show room and I am able to overlap the collision boxes and open/close the drawers with the hand itself, But I want the overlap t happen through the laser

@sturdy coral Which version did you spring for? I'd love to hear your opinion once you get it (hopefully this year)

@fossil sky You don't have anything coming out of Break Hit Result to tell you what you hit with your trace.

@deft moat I think I'm going 5k+, have 8K X as part of my order too but they haven't mentioned the 8K X in months
tired tree
why exactly
mighty carbon
I expressed my dissatisfaction with their decision to release free assets (the ones that a lot of people already paid for before Epic decided to do free assets releases on monthly basis). Hoped they wouldn't do that again. They said Epic rules. I said money talks. Then said I might have to start making my own models to avoid "asset flip" remarks down the road.
Got booted off their Discord.
and I was quite polite.
granite jacinth
@mighty carbon what's their discord?
mighty carbon
@granite jacinth I don't know - I forgot how I got there :/
it's one of those cases when you can shit on your customer and get away with murder 😛
I should go into business of making Marketplace assets 😛
sturdy coral
them going free doesn't take anything away from you
marketplace assets have no resale value
sturdy coral
that still won't take anything away from you
