I'm looking for some Quest related tutorials. Does anyone have a good recommendation for where to look? All I'm finding is Unity tutorials.

I had the first one, haven't seen the second. This is one I had: https://www.youtube.com/watch?v=hEtu-ciPc7g
I'm not sure if Drawers are going to prove a problem like they are in Unity or if Unreal has some better code to handle it. It seems in Unity, when you grab an object, your hand becomes the parent of the object and therefore it then rotates freely. It caused some ridiculous movement of the drawer when sliding it out.
naive fern
Unrealty Simon gives you a link to download his stuff aswell, I find it easier to learn that way. I am only making some very basic stuff tho
fathom temple
I'll take a look, thanks. I'm about where you are. I was further with Unity, but I wanted to switch to Unreal.
Are you using 1.39 of the Oculus plugin? I guess I should ask, are you building your own version of the Unreal Engine from Oculus source or are you using what you download from the Epic Game Launcher?
It looks like Unreal 4.22.3 still comes with Oculus 1.32
naive fern
I am using what i downloaded from Epic Game Launcher, 1.32 plugin it says
mighty carbon
has anyone tested VT in 4.23 in VR (Quest in particular) ?
fathom temple
ok, keep in mind that's an older plugin. I think it's prior to the Quest release, but I can't remember. https://developer.oculus.com/documentation/quest/latest/concepts/unreal-quick-start-guide-quest/ . I've built Unreal from source before. It's tedious, but it works.
That pages I posted implies that 1.32 is fine to work with the Quest., however.
naive fern
yeah, it worked fine, but it fucked up in one of the quest updates the last week

@wicked oak TALl these 100%, this is basically a complete waste - do I need to make my bounds greater or smaller? My instinct says smaller, as it would be better to not even generate a cluster if it won't result in any reduced triangle count, but tell me what you think please
hallow knoll
@naive fern That issue has been remedied in 4.23, but you can work around it in 4.22 as well: https://forums.unrealengine.com/development-discussion/vr-ar-development/1646304-oculus-quest-update-controllers-broken?p=1646553#post1646553

does anyone know if people expect 100% physical interactions in PC/Quest VR games or just roll with whatever game offers ?
for example, in my Go project to go from outdoors into indoors, you just "interact" with the door (point and click) and you get teleported into indoors (and other way around)
there is no way to literally have indoors modeled for the houses and simply walk into them (due to art style and performance considerations)
and it's not uncommon on Go
However, since Quest / Rift have 6DoF controllers, I feel that people expect to physically open the door and enter inside
any advice ?
pearl tangle
Do what you would do in real life. Things work much better in VR when you don't need to explain to somebody how to do something because they already know how to do it in real life
naive fern
@hallow knoll Sounds good! TY chief!
stark wyvern
I'm trying to create an experience room in which people can interact with things but in sequence. So, I was thinking of having an arrow which guide the user to the next destination but I feel that arrows will "break" the immersion because it is an architectural project. Is there any subtle way of guiding people to the next destination or is there any game/project which does this "arrow guide" well?
dim iron
@stark wyvern have the next object you want be seen glow a little, or if its an architectural program, have a light turn on that shines on the object, or maybe even floor lighting to direct to the next object.
stark wyvern
@dim iron A floor lighting sounds like an interesting idea. I'll try it out! Thanks for your input!

guys I'm fucked! I borrowed a friend's base station 2.0 s ... all was good with the index! today with the new fucking update, I tried to update firmware on base stations. it failed in the middle of the process. can't recover either. both stations were with blinking red light. then I tried to manually reset firmware.... now it doesnt even turn on the red light at all ! any help ?
dusky moon
ok so I managed to recover one of the base stations... the other one is although being detected (green light) but not functional
have to send back : /
in nutshell dont update your base stations firmware

Strange that there isn't a simple factory reset option :/
dusky moon
I bet its some HTC shit. cuz these base stations are for Vive Pro. (and It's going to be such a headache to deal with HTC's RMA)
one question! can I use Valve index with [ 1 Base Station 2.0 + 1 Base Station 1.0 ] ?!

About to finally make hte move from 4.20 to 4.22. With 4.23 coming out soonish, is there anyhting major for VR in there?
Im not seeing anyhting major in the 4.23 preview thread when searching VR
frigid kite
I get the feeling that I've not seen anything major for VR from Unreal in a while
mighty carbon
under the hood tweaks and optimizations
sly elk
4.22 had the instancing which was huge for us
is index controller finger tracking easier to implement now or is it still a from scratch solution in unreal?
tired tree
@sly elk you can use the valve plugin for it, but you will have to change up how you handle inputs a bit, for native to engine without their plugin? Yea would still be manual.

Hi all, has anyone run into the issue of VR Preview being greyed out while running ue4 on Ubuntu 18.04 with HTC Vive? I have a VR ready laptop and the headset works with SteamVR but when I try to open a project after having SteamVR running and go to VRPreview, it's greyed out. I've scavenged through the forums without much luck, I would really appreciate some help 😃 (I can post more specs if needed)
supple drum
how do you detect that an image is not tracked any more
I cannot find any exposed callbacks or so in UE4.23 and before
honest mango
Anyone here used the Robo Recall mod kit?
pearl tangle
@honest mango I would say most people in here have at least played around with it
mighty carbon
not me 😛
honest mango
Idk not many people have seemed to. My question was just if anyone knew if anything changes if you actually own the game, I know with the mod kit you only can play the first level
pearl tangle
changes in what way? You don't get more content in the modkit if you own the game if thats what you mean
honest mango
Just if anything changes, if you can do anything different, I havent done much in the mod kit yet. Im guessing not
pearl tangle
@honest mango nope there is no difference
slender pulsar
Oculust Quest uses ES2 or ES3 ?
severe tide
It can use both
slender pulsar
Ty, And is forward or deferred rendering ?
real needle
Hello everyone ! Does anyone has already used OpenXR with Unreal Engine and can explain me how to set it up and integrate it in the unreal platform?
slender pulsar
okay ty @mighty carbon but on UE4.22 is working with Vulkan ?
mighty carbon
You need Oculus fork of 4.22.3 with 1.39 integrations @slender pulsar
slender pulsar
I just see your issue there on the github
okay
it seems like you have issues with the Vulkan
Will use the ES3.1 then
Go and Quest share same system ?
mighty carbon
I do because I don't have Quest 😭
Quest doesn't have any issues with Vulkan
as far as I know
Do you have Quest @slender pulsar ?
slender pulsar
The company have it
will try today
But from what you told me should use the custom version
tired tree
4.22 should support vulkan on quest
slender pulsar
but from what the web list many changes are only post release on their branch
mighty carbon
@tired tree not the stock UE4.. The whole support thing is in the integration, which is outdated in stock 4.22
@slender pulsar it's as custom as if you build UE4 from source..
tired tree
yeah would have to be the integration
@mighty carbon it was 1.39 that finished up support for that wasn't it?
4.23 ships with 1.37 currently
mighty carbon
yeah, 1.39 added FFR, MSAA, multiview and some other things
looks like 1.40 is coming soon too, so stock 4.23 will be so behind again :/
sturdy coral
@sly elk 4.23 may be adding rtx support for VR, possibly usable for dynamic ray traced soft shadows
Says it isn't enabled yet but mentions it a bit in release notes, and I think victorlerp mentioned in here support may come in a later preview
@mighty carbon maybe support both ways, on PC stream in the level in the right place when they get near the door, while on go load into the interior level
mighty carbon
well, I can't just stream in a level because outdoor is smaller than indoor 😃 Stylized art after all
so it's either way have to be a sub-level
I am wondering whether to fade view to black when player swings the door open using 6DoF controller and then load indoors level or keep it the same as on Go - point and click to enter
@sturdy coral ^^
sturdy coral
Point and click to enter is probably fine if it is loading them anyway
That's how rec room does it
I think
Or it is like put hand over it and click, but not grab doorknob
tired tree
in recroom the door opens slightly based on proximity and glows
it shows it being more of a portal that way
sly elk
neat. We are talking about doing our own system for low density ray traced ambient/reflection occlusion. Basically it would modulate the existing lighting and reflections on the assembled parts of the car and help with longer range occlusion that SSAO can't handle well.
carmine moon
@sonic lake I was hoping to ask you a question about the VR climbing system on your youtube channel.
slender pulsar
@mighty carbon well does mobile hdr works with this?
mighty carbon
it does, but it tanks fps
don't use mobile HDR in mobile VR
oh, and I don't know if it works with Vulkan (works with ES3.1 though)
@slender pulsar ^^
sonic lake
@carmine moon sure, feel free to DM me
mighty carbon
Even if it worked you wouldn't be able to use it @slender pulsar
slender pulsar
why ?
mighty carbon
I guess you missed my chat about performance cost
On Quest you have to hit 75 fps or else. With HDR you will never hit 60.
slender pulsar
yeah seen that one
can use ES3 rather than ES2 ?
without the tonemapper ?
I mean there is a huge problem or something ?
in performance
mighty carbon
I use ES3 on Go
slender pulsar
oh okay
mighty carbon
No HDR
slender pulsar
yeah yeah no HDR or tonemapper but ES3
mighty carbon
But I am not sure if mobile tonemapper works in VR
slender pulsar
Will try to edit the engine sources myself
mighty carbon
I have it on and off and I see no difference in performance
You could have LDR bloom, but you'd have to mess with engine/shaders
It would be nice to have Doom 3 lighting with LDR bloom. I am sure it would perform ok on Quest

Oh, if you want to see great graphics on Quest, check out Red Matter @slender pulsar

wary onyx
hey guys i am testing out the handheld ar template the two features i am interested in is the plane detection and hit testing. I wwill like to know if it is possible i can spawn 3D objects without touch input, is it possible to trigger a hit test after a plane is mapped and not via touch input?
spiral oasis
does anyone happen to know if it's possible to get overlap events out of an MRMesh component? physics collision is working, but I don't seem to be getting anything on overlap. generate overlap events is checked, collision channels should all be fine, static mesh overlap events are working between each other 🤔
@wary onyx there's no need for touch input or a hit test to spawn an object on a detected plane.
wary onyx
@spiral oasis how can i make a mesh spawn on a detected plane?
cause i want the mesh to spawn the detected plane.
cause i am making an ocean floor that covers an actual real world floor
spiral oasis
I've mostly been working with magic leap and not mobile, so i'm a little rusty on what exactly you would need to do. 😦
essentially it should give you an event with all detected planes, and you would need to loop over them and decide what to do with each one. mobile AR might have semantic tags like horizontal, floor, wall, etc, but I don't remember 100%. in the past I have used the lowest detected plane as the floor with decent results.
the planes will have location, orientation/rotation, & dimension values. for an ocean plane i'm guessing you'll ignore the dimension and just make it huge?
wary onyx
yes
precisely
@spiral oasis i am new to ar so what would be the nodes i would have to fire to get what i am looking for?
spiral oasis
i'm not sure exactly since I use magic leap primarily, which has its own plane detection implementation. arkit/arcore are both similar though.
are you going off this example? https://docs.unrealengine.com/en-US/Platforms/AR/HandheldAR/ARHowToHitTesting/index.html
spiral oasis
if I had a handheld AR project on this computer I would be more help, but it's on my old laptop :(
there should be pretty straight forward ways to get all tracked planes. there is possibly an event somewhere when a new one comes in, or you can run this to get all the plane data: https://docs.unrealengine.com/en-US/BlueprintAPI/ARAugmentedReality/Tracking/GetAllARTrackedPlanes/index.html
then you can decide which one you want to use as the floor
wary onyx
Awesome, what exactly would i plug this with?
would a screenshot help? i have the project open on my side
spiral oasis
i would run it in tick or on an event when a new plane is detected. find the lowest plane, and move the ocean plane to its location & orientation. handheld AR has a tendency to drift pretty bad and will sometimes put the floor 20 feet below you or something - so that's something that would need to be handled in a perfect world.
not having a whole lot of luck digging around the documentation, but to be fair all documentation regarding AR is pretty bad across all engines 😄
spiral oasis
so nobody knows anything about MR Mesh Component? 😦
mighty carbon
@spiral oasis it seems that no one here is really big on AR (perhaps because you have to hold a phone with tiny screen vs wear VR HMD)
not as exciting as VR imo
spiral oasis
i develop using AR headsets primarily 😄
mighty carbon
which ones?
spiral oasis
magic leap is the main one
mighty carbon
I see
that's another thing - most people can afford Go/Quest/Rift. Less can afford Vive/Index and very few can afford Magic Leap / Hololens 2 (which isn't out yet anyway).
Plus, AR is still isn't as exciting as VR 😛
spiral oasis
not the biggest fan of VR, personally. but yeah, totally on point with the pricing, it's not really consumer friendly yet
trail shale
What is this causing this flickering on the clouds,....only happens on VR, seems to have occured on the update from 4.19 to 4.22
spiral oasis
looks like a problem with HDR to me, but i couldn't tell you why
trail shale
I thought so too...although I realized just now I never updated the Ultra Dynamic Sky....I'm thinking that it was foolish to assume it would update when I converted the project
spiral oasis
4.19 to 4.22 is a pretty big jump 😄
trail shale
I think my dynamic resolution or me using this is broken...what are the correct VR settings for 4.22?
I think steam VR is causing issues actually, I can't see the distortion in the spectator screen
yeah motion smoothing
Yeah, performance is shit and I'm not sure why...the motion smoothing was an easy fix but I'm pull up my previous build for 4.19 and it runs 3x faster
mighty carbon
Has anyone tried Steam Audio on Quest?
trail shale
I'm trying to determine what's so different and why am I frame rate drops big time did they change something with particles?
spiral oasis
@mighty carbon quest is powered by android so if it runs on android, then it should be ok. i never had any luck with steam audio but haven't messed with it in at least a year.

I wonder if they will really fix https://issues.unrealengine.com/issue/UE-75902 in 4.23.1 or will move it to 4.24
trail shale
so how does screenpercentage vs pixel density work in 4.22...i think they ar the recent for my performance tanking when i updated from 4.19
sturdy canyon
Now a 1.0 is what 1.4 used to be

wait so what should I put it on then if I want 1.0? .75?

The new system varies less by platform
But the old system was crazy
trail shale
what about Get GMDstate...that seems broken too
that and my particles (which I didn't change or even open) seem to be more expensive...what should I investigate as the cause?
could ray tracing have been turned on without me knowing?

small question. Is it possible to see what happens on an android device in the editor? or is it cut off and basically android studio is the best I could do?
tired tree
@trail shale always keep SP at 100 now
and adjust pixel density
read the blog post I linked you last night
regardless, this would have been the same in 4.19
mighty carbon
@fickle sky why?
if it's for Oculus, then read this https://developer.oculus.com/blog/developer-perspective-ue4-logging-and-console-commands-for-mobile-vr/ @fickle sky

SP at 100 now @tired tree ???
@tired tree I never messed with it from 4.19 to 4.22 so that's why i was looking for other causes
tired tree
SP 100 is 100% resolution, no scaling with it
you adjust the pixel density now, as it is a static scaler for all of the HMDs and is a lot better

warm lion
So I've created a reach and pull movement system similar to lone echo. When you reach out and grab you grab the world and pull the camera through. This works really well but I notice that there is some small shaking (from my hand actually shaking) that causes a small vibration in the camera as it is pulled through the space. I know altering the natural camera can be dangerous in VR so I'm wondering if anyone has any experience with smoothing a camera in VR and what you experienced. I'm wondering if adding just a small , very small amount of jitter reduction would be beneficial or if it gets weird in VR with motion sickness etc..
sturdy coral
@warm lion gorn has movement like that, you may want to test that and see if it has the same kind of jitter or if they are doing some smoothing
also be very careful of tick order and tick dependencies as that may be your true source of jitter
depending on how severe it is
does echo arena have the same jitter for you?
trail shale
4.19 - 22.9 m/s particle, runs fine....
WHY 4.22, WHY -
55.4 m/s
i'm "pretty sure" it's the VR but I'm not sure
WHY
dynamic resolution not supported? I've read only the consoles have it in, could that be my probleM?
mighty carbon
Turn on particles cutouts in the render settings of the prpject
trail shale
I haven't messed with those particles in a year though, but standby
it wasn't on but i don't think that was it
no particles there
the plot thickens
I think I know what that is
I have a VR function that toggles binoculars ....it also drops pixel density to compensate for the 2Dcapture component used to create the effect of binoculars
going to disable and see if that changes
would the profile say the actual name of the resource? it wouldn't would it ?
trail shale
Also this -
could some change in the VR stuff have caused this change in the render?

Does anyone have experience with the scaling of the VR world being off in an Unreal project? I am using Oculus devices and made a child pawn from the MotionControllerPawn so in the begin play it is calling Set Tracking Origin to Floor Level. My scale for the world is 100 but my actors that are 180 units (1.8 Meters) are showing up as super small. Are there any other settings that I could mess with to fix this?

Are you sure your models were imported correctly? Drag a standard Unreal cube in the scene, it's default size equals to 1m x 1m. Does it also appear too small?

you have to provide a candidate object, so you can do that by scanning it in the app or from another app, then you set the session type to object scanning
wide tundra
Is there any point in me scanning the object which then exports the .arobject ??
I assume Candidate Object Data -> Array are the points within the object I scanned.
mighty carbon
anyone with Quest, care to support my user voice entry https://oculus.uservoice.com/forums/918559-oculus-go/suggestions/38373601-please-add-microphone-input-support-in-ue4-bluepr ? por favor ?
wide tundra
@pearl tangle I see that you mentioned that I can can scan it within my app, but I would prefer to provide the data object rather than scanning it first.
fleet plume
with the support of vulkan on quest/go, does that mean geometry shaders would also work now?
mighty carbon
while support is there, it's not 100% usable
so I'd wait for them to fix it before asking for geometry shaders 😛
fleet plume
just wondering if (limited) tessellation might be feasible now
mighty carbon
try it? 😃
fleet plume
😄
pearl tangle
@wide tundra Yep thats just gotta be referenced properly. From memory there is no way in the blueprint to define it in editor, so it can only be loaded up at runtime so just need to grab it from the file storage. As long as it's the correct format and you created it with the iOS app specifically designed for it, it's not just a 3D model you upload

So does anyone have experience setting up a door that can be interacted with in VR, I'm trying to use a physics constraint and use the below pickup drop code so that the player can open the door.
wide tundra
@pearl tangle Is there some sort of sample, resources or blog post on how to create a Object Recognition app in UE4. I looked around but I couldn't find anything specifically aimed for UE4 only Xcode
@pulsar dome Can you not just call a Raycast from the specific hand to the doors collider and when hit do something.
dim iron
Morning all, I've just installed 4.23 source from Oculus github, on the Quest and the Rift, grasp no longer works and the hands are 90 degrees out. anyone else tried 4.23 built from source and had same issue?
this is a fresh VR template too
pearl tangle
@wide tundra not that I can remember. Pretty sure that you could just toggle the AR mode from "scanning" to "looking for" from what i remember
pearl tangle
ok yep had a little bit of a play. @wide tundra so you create your ARsession and set it to ObjectScanning
wide tundra
Yeah, I did that and added a candidate object which I created as a Data Asset
wide tundra
In Unreal
Idk how to get the points from the .arobject I looked at loading it at runtime but not sure what to load it in and how to actually open it, as .arobject file itself can't be opened in win, I tried to open it in a mac but doesn't return anything.
I guess in Xcode when loading it it can read the actual file.
pearl tangle
it should pretty much be a point cloud sort of thing
wide tundra
So would the data be loaded into the Candidate Object Data I assume.
This maybe since its also for AR ??
pearl tangle
nah thats a different 1 for recording out
inside unreal if you want to record it you draw a bounding box around the object you are looking at and then convert it to a candidate object
wide tundra
I assume the data can be saved for later use??
wide tundra
Does GetARCandidateObject start the drawing of the bounding box??
Obviously once the AR Session is started and the right session type is selected
Not 100% Sure about the first set
Would the first Set get overwritten by the 2nd, or do only the CandidateObjectData gets overwritten
pearl tangle
that bit you have there is to actually set the candidate object
wide tundra
I assume you are talking about the first Set
wide tundra
Hmm
pearl tangle
you start the session into scanning mode and then change session when you are wanting to track
mighty carbon
Ue4 still comes with severely dated ARCore SDK 😒
wide tundra
can't even use arcore on my phone
When I build the sample and tried to run it, it said I need to download Google Play Service for AR but on the play store it says my phone is not supporting this version so I can't use the app anymore.
pearl tangle
@wide tundra you can just grab an older version to run with
wide tundra
Its fine as I am not that bothered with it, after looking online I found it doesn't have object scanning incorporated at all.

do you guys know if anyone has released some info on how they do it?
I guess they are using some kind of calibration stage to align the different tracking spaces
mighty carbon
Isn't it just an MP in the same physical space ?
I don't see why would you need anything special for that - there are no obstacles in the middle
tawdry dragon
You need to make the quests sync to same positions
Their tracking origins are not the same unless you can turn them on exactly the same place
tired tree
@tawdry dragon it wasn't a problem for @hallow knoll to handle pretty easily
tawdry dragon
Hmm, Maybe he can share how he did it? 😃
mighty carbon
@tawdry dragon why though? It's the same as playing online being on the different ends of the world or in the same hall - as long as you don't need for players to be in sync in VR as in real-life (and in-sync with physical obstacles in real life). It doesn't look like those players are in sync (although I didn't watch the entire video 😛 )
tired tree
@mighty carbon he WANTS them in sync in the same room
hallow knoll
@mighty carbon Are you ready for the secret?
@tawdry dragon The easy way is simply to stand in the same spot, look in the same direction, and do a center reset :)
We're usually able to high five irl and VR (we use that as a calibration test)
I have another method where we put controllers in the same spot as well
tawdry dragon
But what are you doing as calibration? Resetting World Origin or?
hallow knoll
@tawdry dragon If all pawns are spawned in the same game world location and rotation, simply resetting your playspace (guardian) center in the same real world location/orientation will sync
tired tree
Controllers in the same spot makes more sense to me personally, but it would take more effort
tawdry dragon
Hmm, I dont seem to understand that.. So your shared space is reliant on people standing the same place and resetting the guardian inside the oculus menu
and then you just go about your business inside UE4 as you would any other VR multi player
tawdry dragon
Yeah as MordenTral is saying, my guess would be having the controllers do it would be nice
I think rebasing the world origin would be the easiest way of doing that, but it seems very bugged when doing it while networking inside UE4
tired tree
@tawdry dragon with a common known orientation is isn't hard to rotate the yaw of the pawn and reposition to sync
compare the position and leveled yaw of the controller to the known expected position
or even use the server as the common if it is unknown and calibrate to the servers placement
tawdry dragon
hmm, not sure I quite I understand that. Say you have 3 players, where #1 is the server. His Quests tracking origin(or server world origin) is in the center of the room. The two others tracking origins are offset physically by a couple of meters, so their world origins have different distances from the servers world origin. Now when the server spawns a enemy at a location, that location needs to replicated and changed for each players relative distance from the servers physical origin right? Or am I completly overthinking this
tired tree
@tawdry dragon before gameplay
have the server set its controller or stand at a specific spot
record that as the "server native" location
everyone else can do the same, and you rotate the pawn to line it up with the servers
tawdry dragon
but is rotation the only thing you need to do? Doesn't the world origin and everything need to be completly the same if you are spawning projectiles etc.?
https://www.youtube.com/watch?v=G0WHhNQpf9I is basically what you need to do as far as I can see. But his code and example project doesn't work past 4.20
It got merged into the main ue4 branch, but running his example doesn't yield a result that works
tired tree
@tawdry dragon projectiles are on the server?
you are just aligning the player to the relative loc in the world that they should be from the server
you don't need to do any rebasing
you are adjusting their "real world" position to sync tracked spaces
tawdry dragon
hmm.. I still cant wrap my head around it.
So your flow would be:
- Place the player controller at the same physical location before the game starts
- Record the orientation for the server
- Have each player do the same and rotate their pawn to match the same "ingame" orientation
- Start the game
tawdry dragon
but its only the pawn you're manipulating?
tired tree
you ARE talking about people in the same room right?
tawdry dragon
yep
tired tree
yeah only the pawn
the tracked space is relative to the pawn actors zero point
not the world
tawdry dragon
Not sure I understand. In my head you need all the different players ingame origin(0,0,0) and orientation to match same physical spot in the real world if you want the shared space to sync up
or atleast have code that compensates it
so spawning an actor on [50,50,50] on the server is the same physical location on all the different players quests, even if their initial tracking location is not the same
tired tree
that is the compensation
you are placing the controllers in the same spot in the real world
and then aligning them in the game world
tawdry dragon
Yeah, but wouldnt you need to write that compensation into the very core of actors replication?
tired tree
no
you just move the actor
are you expecting to use locomotion with this?
because yeah, then it gets more complicated
tawdry dragon
I'm just thinking about copying the arena shooter I linked earlier
with projectiles spawning and using physics around the world etc.
tired tree
yeah thats just syncing them into the same space
the game doesn't have to care about their location
you are just making sure that they are oriented correctly and any offsets are corrected for
you aren't moving their game world around, you are moving their Real-Virtual tracked space alignment
tawdry dragon
When you say corrected for, what do you mean by that? Is that when you are replicating the location of the actor from server to client or just offsetting the pawn on the client initially
tired tree
just the offset of the pawn
tawdry dragon
only on the client right?
tired tree
would have to be done on the server if it is server auth movement on the pawn
think about it like this, X is server controller and Y is player controller, if placed in the same real world position they are X Y then you just need to re-position the client by the difference to make it XY
you are lining up the tracked spaces
its easier with steam VR because you can clone layouts to lighthouses
tawdry dragon
Still having the trouble wrapping my head around why that would work, but I guess I just need to try it out in a prototype 😛
So flow is:
- Server starts up, move to physical calibration spot and stores that
- Clients connect, go to the space and sends the offset orientation and location to the server, which then moves that players pawn based on the values
- When all players have done that, game is synced and ready to go
tired tree
should be good yeah
you just need some common location that is known to all in order to adjust
i would assume that this could be done with boundry detection of obstacles from the oculus side of things eventually
but they haven't released anything regarding it yet
north verge
Hello people, I have a quick question, why does my vive wands trigger axis always returns 0 or 1? Isn't it supposed to be also in between?
pearl tangle
@north verge make sure it's the trigger and not the grip 1 that you have on there, and that it is configured as an axis and float on the other end
north verge
Here is how it looks in the inputs tab
And Im printing it out here to test and its always 1 or 0
north verge
Figured it out, apparently there are two trigger inputs in the axis section, one called trigger and the other trigger axis.
rich canopy
@tawdry dragon there are ppl looking into using azure anchors for the shared space syncing but thats gonna be more complicated than any manual syncing. Manual syncing works but its gonna be tough to get oculus to approve that unless its just your own project.
tawdry dragon
One would think its crazy to think they didn't include any shared space in their SDK
The other headsets should be able to detect the other controllers and communicate with the other quests in order to triangulate a common tracking space
clear abyss
Hey, if i use the VR example and i drop the VRMotionPawn, it doesn't work and it will "spawn" the default spectator pawn on the last pos of the Editor Camera. What do i have to do? Adding Player start and setting up custom GameMode and selecting the pawn as default didn't worked either and the example maps doesn't have anything like that a yet they work
Could somebody hint out whats the issue or the general principle of which character controller should be used and when?
mighty carbon
@tawdry dragon probably because it wasn't trivial? Carmack said at some point they will add that functionality, but at this time it's at the bottom of priority list
hoary reef
This seems like the wrong place to ask but I'll give it a shot. In the VRExpansionPlugin there is talk about attaching to sockets, but the way the gun in the example level doesn't appear to match the documentation at all and I can't figure out how it's working. I deleted the entire event graph and it still snaps fine, but the sword which also has a grip doesn't want to snap. Whats the difference between the two?
tired tree
@hoary reef what sword? the ones in the side room?
or the one up top
the one up top has the socket snap range set to 0 so that it won't snap
hoary reef
The one up top for slicing. Also your the guy. Neat
tired tree
yeah it has the socket turned off
as for the gun in the level, it has the VRGripP1 and VRGripS1 sockets
it does follow the documentation
hoary reef
I'll take your word for it and assume I am too new to follow it then. I nuked the entire event graph in the in the example for the gun and the slicing sword. They both still operate in a way that one snaps and the other does not. What section do I need to check for to determine how to modify this snapping behavior?
Trying hard, just very new and taking in a lot. Making my first not simple toy game.

So after packaging my VR game for testing I found that the fps in the HMD is horrible, but I'm getting 60 fps in the VR preview window, how do I reprioritize?
spiral oasis
tired tree
@hoary reef the interface dictates the slots, not the event graph
the event GetClosestSocketInRange is queried, if you don't override it and implement custom logic then it uses the default of choosing by name prefix and range
hoary reef
@tired tree I'm an absolute idiot. I thought I checked all the settings but I see it now. Thanks
hoary reef
For gameplay tags if I want to disable dropping in one hand after forcing something in on beginplay event what set of gameplay tags do I need to put in. If I place something with this in world it works after I grip it.
I think I'm missing something here when spawning programmatically. I think it overrides the default for drop and removes the bindings for it entirely as I understand it.

Apparently, I do. It seems Unreal doesn't download the Android NDK and SDK like Unity does. I'm not sure if that's good or bad -- not tying the engine to a given Android release. Probably better.

Running on pc @pulsar dome?
pulsar dome
Yes @severe tide, running on PC
@severe tide why does that matter? Do you have an idea?
severe tide
Well if you developed on pc and packaged for quest for example, it would be different 😊 only that
But no then I’m not sure. What FPS are you getting in your HMD? Even 60 isn’t really enough for VR
pulsar dome
Yeah, so I'm developing on windows and packaging for windows, testing only, and the issue is that I'm watching the preview on my monitor and watching my hmd like by sliding it halfway up my head, and the hmd screen is a whole lot laggier than the preview, so I'm just wondering if that's due to ue4 prioritizing the framerate of the preview over the hmd?
severe tide
I wouldn’t think so, the preview shouldn’t be a bottleneck
Try running some stat commands to see where the resources are going
pulsar dome
I need to do a lot of optimization ofc but I just find it curious that the preview screen seems to be a lot less laggy
severe tide
But again, if you’re running at 60 FPS then that might appear laggy in the HMD but not on the monitor. Unless you think the HMD FPS is even lower
pulsar dome
I believe it is lower, I'm aiming for around 40-60 fps per eye in HMD
Do you know if there is any way to disable the preview, possibly in blueprint?

Hey everyone, anybody knows how to get the AI Perception (sight) from an AI Controller to see your HMD?

@idle osprey You should install the version that ships with the engine. It's under Engine/Extras/Android if I'm not mistaken

@hallow knoll Hmm, but it doesn't also install ant, does it?
hallow knoll
It will install everything required to Launch on device, and install your development builds
spiral oasis
@little scaffold admittedly i don't have experience with the rift s, but it looks like it targets 80fps and if it's anything like vive, it will throttle to half of that if it can't reach 80fps.
little scaffold
@spiral oasis I've been working on Vive before but never saw that... So it means it can't reach 80 fps or should I consider it as half of the fps?
spiral oasis
vive will typically not let you get 60fps for example, it will be either 90 or 45. you could try loading a really simple level and see if it hits 80

@stark wyvern nav mesh bounds uses the bounds of the object to create the shape, the bounds of the cylinder is a box.
You’ll need to setup collision on your building and this will automatically redraw the nav mesh based on where the walls intersect the nav mesh bounds volume

I thin kwe are going to go with the steamvr beta and then fallback to vive bindings for people who don't use it

@sly elk its not Beta for SteamVR, its a beta implementation in engine
SteamVR itself is fully on the new methodology, they support legacy apps with a translation layer
ue4 currently is default on that legacy translation layer

from the users perspective the only real difference is the names of inputs when they go to rebind them in steamVR
limpid lava
@spiral oasis can elaborate on that response?
spiral oasis
which?
limpid lava
"looks like that function always returns 0" assuming that was an answer to my question
spiral oasis
ah i see, yeah that was for you. i assume that function is hooked up to a UMG element?
limpid lava
Yes, I have that in MotionControllerPawn hooked up to a widget controlling the progress bar
spiral oasis
the return value is hardcoded to 0. it would need to return 0-1 percent... so like: timeHeld / maxTime
limpid lava
Still wrapping my head around blueprints, so if there's a more efficient way of going about it, I'd be interested in trying that instead
spiral oasis
that's the way i would do it
not sure what that anim is doing though
but i'd probably get rid of the branch and return timeHeld / maxTime
limpid lava
Just have the animation of the bar filling up, I was trying to get the bar to fill up, and tried that method
spiral oasis
ah yeah probably get rid of that and just return the percent
limpid lava
But the problem with that is it would probably not fill up as the user held the button down
spiral oasis
probably get rid of the part in red, and add the green
excuse my mspaint skills 😄
maybe clamp that value to 0-1 also
limpid lava
I'm not sure about the max time, but I have the float variable, Hold Time, from the pawn plugged into the return value with a clamp. Hopefully that's what you meant.
spiral oasis
that won't work
you need to divide by the target max hold time (3 in your case), or use map range clamped
map range clamped might make more sense since that's exactly what you're doing
so plug that hold time var into map range clamped, with input range as 0-3, and output as 0-1
limpid lava
Hmm still seems to be instant restart as soon as I press the grip, even with the Map Range Clamp, is it possible something in my Pawn's blueprints are wrong?

hey everyone! o/ does anyone know if Epic has any plans on catching up with the implementation of the current release of ARCore? The new (preview) UE4 release will only feature arcore v1.7, current being 1.10
mighty carbon
probably not @wild stratus
wait for OC6 announcements, maybe Oculus will have some AR shades to show with functionality better or comparable to ARCore
wild stratus
Well I don't have an oculus.
But yeah, I might just switch to Unity as it currently supports the actual ARCore release
Thank you for clarifying
mighty carbon
btw, I am just speculating
wild stratus
I understand that's the only thing we can do as neither the official communication nor the official roadmaps are much clear in this regard xD
trim spire
I will look into that section @mighty carbon ! The solution I found was to call the java method "StartActivity" from C++. I'll try it next week.
Thanks for your answer ;-)

Anyone have any smart suggestions on testing online multplayer VR? My current solution is to run on two seperate machines
Second player does not require VR, keyboard and mouse is fine.
doing "VR Preview (Play)" nearly works second player can do kb/mouse, but VR seems non-functional for the first

Hey guys, i packaged my games to oculus quest and the texture resolutions is pretty low.
Do you think, that making textures lowres manualy would help anything? I have 1024 mostly, if i cranked down to 512 it should help right?
Or in better case, is there a brutteforce solution so i could get the best and worry about fps later?

What's the best way of achieving hand collision in VR? I've been experimenting with controllers attached with physics constraints and also physics handles but none seem to be good enough. Has anyone found a better and more practical way?
hoary reef
How does a game like beat saber handle calculating angles before a collision happens. Crazy idea I am currently floating is an invisible collision box attached to forward vector and then mathing out stuff.
Invisible forward vector collision 'cone'-> if collision linetrace to determine no blocking objects-> check if saber collision -> follow through distance and math out the entire angle.
Is there a better way to go about this?
hoary reef
Waaaaait. I'm being stupid. I know the position of the boxes and I know the position of the saber. I can just line trace directly at it and skip this cone nonsense.

Hey, i'm trying to achieve some sorting with the new composer and it seems i can't select the target camera which is on Pawn, but i can choose a Camera Actor which i would add directly to the scene.
Any clue how can i set the camera?
I've tried to get anything from the CompositingElement via blueprints, but i could get as far as the passes, but no reference to any camera variable or anything. Only the Find Target Camera which doesn't help.
Upon starting it creates it's own camera on 0,0,0 and the controls from the VR headset goes there. Am i really unlucky because the feature is in beta, or do i use it not correctly? 😶

Hi all, currently profiling a VR project and noticing we're getting (predictable) spikes in frame time due to Oculus stat "FinishRendering"
Any way I can get more information about why those frames are taking a much longer time than others? Thanks
@neon egret I know you work with Oculus, don't suppose you've got any profiling tips for breaking down why the above spikes are happening?
neon egret
Nope, only did gameplay code and session stuff.
manic ledge
Thanks for the swift reply - no problem! Don't suppose you know anyone who might be able to assist with this?

Also nope, not really up to date with the VR scene anymore.

No worries 🙂
Additional info for anyone else reading this - I've been able to consistently repro this issue. I understand "when" it's happening, just not the "why"
If anyone can point me to a way to trigger a profile GPU on the specific "Hitch" frames, that would be fantastic

what about differentiation between Go/Quest and Rift @ember forum ?
ember forum
thats a different function
its in the oculus library
@mighty carbon
anyways its valve that stepped on the ball, not epic... since its their plugin (the steamvr input plugin)
i guess it doesnt matter, because you have to deactive the oculus plugin in order to get it to work anyways
and then it just emulates your hmd as steamvr
whatever, its free and it has finger animations, so 👍
mighty carbon
oh, so you can't have both plugins enabled if you release on Steam ?

Well from what i tested, the steamvr plugin replaces the oculus plugin so you have no need for it... i might have been able to remap the oculus buttons to make the inputs work, didnt try tho... so not 100% sure

Any one uses full body IK for their avatar? Was wondering where I can find some tips to make some thing like what Pavlov has.
shadow radish
basically when I show videos of my game, sometimes I get market feedback that they are sick of wave shooters
I'm trying to build a game that can satisfy the arcade market but also have depth singleplayer
so I am wondering what your thoughts are on the market, whether people are truly sick of wave based games or if that's just a vocal minority?
when I look at story based games like karnage chronicles and primordian which seemed very polished and don't do as good in sales as blade & sorcery and GORN--it leads me to think it's just a vocal minority?
@rich canopy I'd also be very curious on your question--I haven't tried doing an avatar yet but want to eventually
tired tree
@ember forum no, the input plugin only functions if you are using SteamVR to begin with, which means that you are not on the native Oculus layer if it is functioning. I did notice the statement saying to deactivate the oculus plugin if using the input plugin, but as far as I am concerned that is something that they need to fix, it doesn't conflict in base engine and it shouldn't with that either.
north verge
I would agree with you there, there are tons of well made single player VR games but most of the time they do worse then poorly put together wave shooters. Its probably best to pick the path which is less riskier in my opinion.

@shadow radish that is a million dollar question right there

Other than some great marketing on both their parts. They each have unique gimmicks that appeals to those that enjoy it (I don't have either game, so I guess I'm not appealed 😉 )

@granite jacinth I enjoyed both - looking forwards to B&S single player adventure mode

Yeah, that game did some great marketing
And delivered absolutely nothing
Well, I can't say nothing. But...from all the reviews I read when it launched
"Not much"
And it's kinda incredible how much players don't mind it
dense lance
Well, mostly I played taking turns with a friend, on ever-increasing difficulties - I sure do agree it could do with more going on.
But hey, solo dev making it, we prob spend more on beer (well, fancy cider) the first evening we were playing than the cost of the game, I'd consider it worth it even if there were no more updates
(though, will still grumble if the promised single-player adventure does not happen - most of the required elements are there, perhaps most of the work needing doing is a bunch of interesting levels. Perhaps he has grander plans though)
mighty carbon
I personally dislike MP games, but working on single player game (for Go) I can tell you it's not the easy route for a solo dev
throw in 6DoF controllers and expected true physical interactions and you just increased dev difficulty 10 fold
(especially if not using VRE or something similar)
tired tree
@mighty carbon actually all of that is fairly easy in singleplayer
physics interactions kind of just run themselves, which is why you see a lot of devs going pure physics
its when it is multiplayer that it gets harder

the issue you can see is my weapon scope sight, which at the moment is just on a flat cyclinder attached to the weapon, is really delayed with the vive pro. also the weapon stutters a lot (cant tell in the video) in the HMD it is really jittery and meltey.
tracking solution is 100%. have turned off all other programs. GTX 1080, i7-6800K. have tested the vive pro with other games.
will post this to the forums and reddit too but if anything stands out to anyone would be appreciated!

if you go into steam vr overlay, does your controller track smoothly or jerky like in ue4
like, do VR preview, press the menu button or whatever on the controller, does the mesh shown there track smoothly?
sharp shell
are you explicitly moving the weapon around using get tracked device position and orientation?
or are you using the motion controller component
@real needle
also, not that it should cause that level of weird movement, but are you monitoring your framerate to make sure it's stable?

not sure what you mean about it should cause that level of weird movement. movement is fine with rift s, but borked with vive. uses the same code
kinda fucky hey. this was half from the vr example, and half done by someone else (the top bit)

hoary reef
I’m a bit embarrassed on this but what point is the dividing line on when you want to drag in something like the vrexpansionplugin? I’ve been working with the example but it’s got so much stuff I don’t need that is just confusing me because I’m too new to know enough to know how this whole thing is stitched together.
The main reason I was looking at it was because the of full room replication but is that enough to justify using it?
tired tree
@hoary reef as the creator of that, when you run into a wall and don't have the c++ ability to reference the core code and do it yourself. That example isn't made for a game base, its made as a bunch of reference examples of interactions. Also the plugin itself is on the advanced end of things and unless you need something exclusive to it I don't suggest using it.
That being said, roomscale replication may actually be a breaking point to use it if you need it more than just for the controllers / hmd (body). And even if you do need just the controllers / HMD, those are useable stand alone and without all of the rest of the framework.

celest thorn
I'm pretty sure I'll feel dumb once I solve this, but I've hit a bit of a brick wall today. I'm IKing/rotating my head, wrists and such using the HMD and motion controllers, but skeletons in UE generally face forward in the Y direction while level elements, like my VR camera / MotionControllerComponents face forward in the X direction. Because of this, even though everything looks good when I'm facing forward, if hop into game mode and nod my head for example (which is a rotation in my VR camera's Y axis,) my skeleton mesh tilts it's head from side to side (which is a rotation in the X axis but from the skeleton's perspective it is it is the Y axis.) Same thing happens with the hands, essentially everything rotates on the wrong axis. I've used some other people's work as reference and I'm not sure what I'm missing, as they seem not run into this problem despite taking all the same variables into account.
sharp shell
however you are feeding the motion controller/hmd location to the anim bp, just swap the X and Y on the vector

hi folks, just getting started with VR in UE4
the documentation says to install SteamVR's beta branch, but since switching to the beta, I can't get it to recognize my Vive
is that documentation still valid?
I also noticed that there's a big notice in the SteamVR UE4 documentation saying that there's stuff in this valve doc that can't be ignored, only to find a document from, I guess, 2015, that dealt with early devkit Vive-specific instructions on using base station sync cables and such
none of it actually seems to apply. gonna just try the stable build of SteamVR for now
hm, the stable branch reports the same "headset not found" error... the only thing that's changed since yesterday is that windows 10 rebooted overnight for an update
I really hope that didn't just break something
ok, unplugged the link box, replugged, restarted steam, seems fine. I'll just use the stable branch for now, and if I run into issues, see if that process enables the beta branch later on

@mighty carbon any reason to build with arm64? I'm doin' a quest build

I don't think there is a reason really @silk lodge
first off, you can't - Audio SDK is still 32bit I believe (the one that comes with UE4 integration)
there are no benchmarks showing performance gains for 64bit over 32bit ARM (at least I couldn't find any), so I don't really see how 64bit is more beneficial than 32bit

For the record, my problem above was cause by me combining the rotators in the wrong order. I was first inputting my HMD rotation, then offsetting it by the axis correction. They had to be swapped. I didn't know there was an ordering difference

I don't know if it's entirely viable to have a clip-less IK solution.

Does anyone know why I get a selection outline in one eye only with an Oculus Rift S? Turning selection outlines off in the settings doesn't change anything in VR. It's really hard to look at

I also tried setting the alpha of the selection color to 0 but that doesn't do anything.
The only way I could work like this is with one eye closed while manipulating actors
blissful reef
Is this a bug or is it supposed to only show in one eye?
blissful reef
Also, is there a trick to getting auto-entry to work? Having that box checked doesn't do anything. I have to press the VR Mode button everytime. It exits VR when the headset is removed but doesn't enter.
blissful reef
Here is the selection outline problem. Such a bummer.
You can see it better in this one
blissful reef
Someone on the forum said that perhaps its a bug because it looks like it's a feature that isn't stereoscopic like raytracing. If that's the case though, then why can't I turn it off in the editor settings? I can't seem to find a VRed. console variable to get rid of the outline.
sturdy coral
@blissful reef try turning off instanced stereo, or turning it on if it is off
blissful reef
Oh man, you're my hero!
It worked.
Now if I can only get auto-entry working then it will be flawless. Thanks a million for the help!
blissful reef
Hmm I think that degraded my performance quite a bit.
sturdy coral
@blissful reef yes you should make the right choice for your game for what you ship with (instanced stereo adds slightly more geometry cost but lowers draw call cost and potentially lower memory bandwidth usage on small objects) and not base what you chose on working around the outline issue in the vr editor
but it at least should let you use the vr editor when you want (after huge shader recompile..)
if you can reproduce it in a simple project I would file a bug report and try and get it fixed
blissful reef
@sturdy coral That sounds like good advice. I did file a bug report so you're right, at least I can use the editor until it gets fixed.

sly elk
we are implementing full physics interaction between parts in wrench, including held parts. Is there an expected way for this to work?
idle osprey
I'm just starting to learn how to use the Quest with Unreal.
sly elk
right now the hands decouple from the motion controller positions, which doesn't feel great
I assume its better to have the held object decoupled from the hands and always track the hands correctly?
but i have also seen games on youtube (boneworks) where they clearly break tracking from the motion controllers to the hands.. Are there rules to follow if you do this?
sonic lake
@sly elk my two cents. Decoupling hands from the motion controllers has serious safety implications. You lose visual feedback of where your hands are IRL. You may more easily smash them into a wall or desk or computer screen. I would not recommend going down that path.
Using Physics Handles to grab parts may be the way to approach it. It allows the held parts to interact among them and with the environment and, at the same time, preserves the position of the virtual hands respect to the controllers.
sturdy coral
@sly elk in the new lab physics update when the hand breaks away they render the motion controller separately at its real position
I think lone echo felt the best for me, but I haven't tried some of the newer pure physics stuff like blade and sorcery
if I remember right lone echo does something like show your hand as a skeleton that renders from behind objects when it breaks away
echo arena is free to check out but has less interactions to look at than lone echo
I liked the skeleton on break-away over the controller on break-away; I'm not completely sure if that was lone echo or something else
bronze raven
How can I get all the locations of the tracked planes?

@sly elk ghosting the hand when far enough pretty much the best like @sturdy coral said. Also you may want to test any initial things on oculus for now, as 4.23 brings a fix for steamVR that will bring the latencies about on par with each other. Prior to that the steamVR controllers have a much higher latency on the game thread so its not really a good indication of the real delay.
Also the real world position still triggers any guardian boundries and since its very easy to lose placement of your real world position in VR I wouldn't consider "hitting a screen easier" as a large enough difference to concern yourself around

how do i make things grabbable in vr?
sonic lake
@barren cairn the easiest way is to make a copy of the BP_pickupcube bleuprint from the standard VR template, edit it to replace the cube with your own mesh and, presto, you have an object you can grab
barren cairn
if i wanted to add some stuff i would just add things right into that bp right?
sonic lake
Define "some stuff"
sonic lake
Your grabbable object can be made of different parts and you can "assemble" them within the same BP. In this case the handle + the laser beam
So yes

You are welcome

@barren cairn facebutton is a generic name. Each facebutton is mapped to a physical button on each different controller. On the Oculus Controllers, they are mapped to A B and X Y.

Hi guys One question related to Oculus Go.
Performance wise how good is physics simulation .
I have small 40 meshes which are doing physic simulation but whenever i use them , FPS drops to 4 5 .
and how would you create an effect of a mixture of sand salt and iron fragments.
Which can move inside a beaker when beaker is tilted.
It dont need to look very realistic.
Help please.
mighty carbon
sounds like you shouldn't be simulating 40 meshes on Go @chilly pasture
chilly pasture
yes you are right ?
Any idea to mimic the effect, other than physics simulation

nope, no idea
in fact, you don't want to simulate anything on Go
do it in 3D app, bake it into cache and export into Alembic

lol @sharp shell . To clarify I am trying to find a way for the mannequin to change into a crouching animation when crouching to a certain height on the HMD

ahhh so you're trying to do full body IK
there's a lot of tutorials about how to achieve it, from my experience it's fairly difficult to implement properly

I tried looking them up, and either they already have the blueprints setup and are showing how they edit or it involves a plugin that costs money......so far

one way I've thought about, but not implemented, was doing some kind of foot to floor IK solver, and to crouch you would reduce the collision capsule half height based on the HMDs height
What I would do to start is to start making your anim bp and add some effectors in the world that will act as your HMD, and controllers, so you can play with them without VR testing until you have something that works
start looking in to things like FABRIK and CCDIK (animation blueprint stuff)

I walk you through how you to use the animBP for arms and torso. You could add more modify bone-nodes and use a vector or a scene component to drive the effector transform of the feet https://youtu.be/ehK6j6Es-ck

omg forgot about that stream

It won't look amazing, but it works 🙂
tender raptor
This is awesome! Thank you both for the help!
sharp shell
victor, I know you handle torso and arms, do you have a preferred method for crouching a full body mesh?

I've only done experiments and generally prefer to design without legs, but I'm planning a follow up to the livestream 🙂

Is there a cleaner way of handling widget transitions than just juggling the widget component down as a parameter everywhere?
