why is it considered mobile if it is targeting its own hardware tho...
sorry if thats a dumb q
granite jacinth
They really all suffer from the same thing vs PCVR
Quest/Focus just have a little bit more power
But it's not that much tbh
golden snow
Its specs are on par/slight above say, the Go.
But, then back on tracking -- it can track like a Rift/Vive(ish)
granite jacinth
Oculus has a 3-prong strategy
Low End Standalone, High End Standalone, High End Tether
Go, Quest, Rift
Well, I suppose "High End" Tether is debatable
golden snow
Vive Eye?

Ooooh

Obviously we have even more "high end" high end HMDs

Quest is new mobile standard
mobile with solidly good 6DoF tracking
that should be minimum requirement for mobile VR
sturdy canyon
I think it will be going forward
I'm excited about the possibility of a Sony VitaVR
Even though absolutely nothing has been said about it
I think it's a cool possibility and maybe a good idea
limber tusk
how about, in terms of as a learning platform for VR development. do we think quest will be more accessible because of price and built in tracking, bringing in new devs? or do the limitations make it more challenging as weell
golden snow
I'm still using my Go for out-door field VR stuff with a tool I'm developing, but I'm on Quest here out.
Unless quest works at night in the middle of a field with nothing to track besides the ground.

ember forum
developing for quest you have to learn about mobile lighting and rendering
golden snow
Quest is, almost unanimously from devs I chat with, the go-to entry way for VR now.
ember forum
thats an art in itself
limber tusk
what do you mean reinaldo? how to optimize those for mobile?
ember forum
but once you do learn that, life will become easier, because you'll have passed the hardest part, and be able to scale up
you have to worry about things you wouldnt have to on rift for example, lighting has to be mostly static, materials need to be cheap to render, low poly... kinda stuff you dont need to worry about AS MUCH on pc vr
so not only is it challenging if you are learning to develop games, and learning the programming part, you will also have to master the art part fairly early on if you plan on getting something running at 60/72fps on the quest
im still kinda hoping vulkan is fully supported sooner rather than later so we can push the graphics a bit further and let the cpu breathe a bit more... because with es3.1 you are really limited
but then again, robo recall looks great lol... but thats a whole team working on a title, for us single indie devs.. its tough learning to optimize and dev at the same time... its doable, certainly, but more difficult than most other platforms
ember forum
sure thing!, i do think quest is the way to go with VR, wireless, so if a person has the patience and willpower to learn how to develop on it, go for it
golden snow
That all being said -- there was a blog on the Robo Recall Optimization π https://www.unrealengine.com/en-US/developer-interviews/learn-how-drifter-entertainment-leveraged-elegant-optimizations-to-bring-robo-recall-to-the-oculus-quest

do you guys think it will be possible to do some amount of mocap with quest?
tawdry dragon
3 points of tracking aint much with mocap
you basically only have your head and 2 hands
no elbows, torso, knees etc.

supposedly Quest is sold out everywhere (except probably Oculus themselves)

In a VR character, do you NEED to have a VR origin to set the camera up?
limber tusk
@tawdry dragon will it be possible to add like additional trackers to quest potentially?
@mighty carbon google express has some where i live
wow nvm it is sold out π¦
mighty carbon
lol, some one these articles praising Index...
pearl tangle
@mighty carbon why wouldn't they be? Seems like a very impressive headset
mighty carbon
because A. it's expensive B. there are no exclusive content (matching quality of the HMD) what would make people think of shelling out $1000
and I mean Polygon's review in particular
pearl tangle
A. Cost doesn't always matter. People don't buy a Ferrari because it's cheap
B. It makes any content you already have better and there will be lots more content that does match it because of it's controllers which are a mile better than the original vive or vive pro, both of which were expensive and have both sold quite a few headsets
toxic oracle
For me personally I don't think I can go back to a wired HMD after using the quest
I don't really care about graphics though
pearl tangle
yeah i think the quest will be great for a lot of use cases. Not something that's going to be used in enterprise side of things though unfortunately except for the most basic of stuff
being able to read text easily in VR is a big deal for lots of things and being able to wear it comfortably for hours at a time as well. I struggle with the quest for more than 10 minutes, need to keep shifting it around
ember forum
yeah comfort on the quest is trivial
sturdy canyon
The index is the first headset since Vive that I will purchase for myself
Quest I didn't have to purchase or I would have
Quest and Index are the first headsets that improved on anything I care about
Rift S I might buy if I'm going to be traveling and need a dev headset that's easy
Luckily I only need to buy the index headset, not the full package
ember forum
there you go... the oculus index
pearl tangle
i would buy 1 if i could. And I already have 2 samsung odysseys sitting around doing nothing, a rift which I have given to a friend for a few months after taking it out of the box once when i first got it, and a vive with a TP cast that I haven't bothered to plug in in over a year after moving house twice
ember forum
my process with the rift is like this... omg im gonna play skyrim.. lets organize the space, untangle the cables, alright steam vr wont run it, lets restart steam now that ive pluggin in the cables again... alright lets goo... okay, wow im so tired (15 minutes later)
pearl tangle
yeah rift S is definitely the right move for facebooks goals of mass. Cameras and lighthouses are a bitch, but lighthouse and knuckles are by a mile the best input and tracking system
quest just makes it so much better to just pick up and play something for half an hour, which you hardly ever do with complicated desktop 1s because of the fucking around
mighty carbon
@pearl tangle Rift has sweet exclusives + everything else.. Vive/Index has only everything else (which isn't really great compare to Rift exclusives)
ember forum
it is https://www.mamutvr.com/products/mamut-touch-grip .. iu thought it wasw a joke but its not
and its sold out
mighty carbon
heh, sold out too :/
pearl tangle
@mighty carbon why do exclusives matter when you can play those "exclusives" on the index anyway?
tired tree
@mighty carbon headset to headset index looks to be far better than oculus current generation, for its features. Oculus is just betting on cost to quality ratios. Exclusives are just exclusives, they shouldn't reduce or increase praise on the hardware itself......
you don't have to blindly follow a single company you know, the entire ecosystem provides utility....
mighty carbon
I know hardware is great.. I was saying about they way they write about it.. Polygon in particular
tired tree
it looks amazing
why would they not praise it highlyu
as much as I wanted quest for the convenience, I am salivating over Index.
pearl tangle
its a massive step up over oculus hardware, nobody can deny that
it would be great if it was cheaper, but thats the unfortunate price you pay to try and get the best quality of stuff
sturdy coral
Price is definitely an issue, especially if you aren't upgrading from Vive so have to buy the basestations
I'm almost most excited about the audio.. VR needs better bass
odd garnet
mighty carbon
I wonder if Oculus will release something like Deluxe Audio strap for Quest
pearl tangle
@sturdy coral I think knuckles are the biggest deal to me with it. Vive wands are shit compared to touch controllers. I wish they had put eye tracking in there though as well, need to start seeing that in a wider range of headsets
sturdy coral
Oh yeah, those for sure wasn't thinking of the controllers
odd garnet
the controllers are π£
mighty carbon
ember forum
@mighty carbon i dont know if you seen rush on the go/quest but they have this aggressive lod system that i wish i knew how they made it... you see the mountains that are actual 3d meshes popping in as the player goes forward https://youtu.be/4MyWPMnQnS4?t=194
mighty carbon
it's not the same as PVS culling
sturdy canyon
I asked Valve why they didn't do eye tracking
They said no eye tracking tech is good enough yet
Vive pro eye has 1Β° noise error which is pretty big, but it also has latency and systematic error and needs recalibration regularly
But yeah I'm really excited for when it's good enough
pearl tangle
depends what you are trying to do with the eye tracking i guess @sturdy canyon . For foveated rendering and dynamic focus it works fairly well
convergence stuff as well thats doing shifting lenses it also works fairly well with
sturdy canyon
You have one already?
When I tried it at CES it was not useful for anything except maybe social presence
pearl tangle
I have a fove lying around somewhere, but have also played around with some different stuff from Tobii and sensics before
there are some guys out here as well that have been doing the moving lense stuff as well from a few different eye tracking setups and it works quite well
sturdy canyon
I haven't tried all the things, but I was unimpressed by the tobii/vive stuff
Combining it with moving lenses to get variable focus might be cool, but a 1Β° error means you better not have small objects behind foreground stuff
Also if you do anything active in the headset and it shifts on your head, you have to recalibrate
pearl tangle
yeah definitely not perfect yet but thats something that a software fix can probably solve rather than hardware
pearl tangle
wow that was weird. Just turned on my quest and the right eye didn't come on right, was just blue... Let the screen switch off and back on and it sorted itself thankfully
mighty carbon
Hopefully new Quests will have all the small issues ironed out in the future production batches
that's one of the reasons I am not buying one just yet π

they can work ok outside, but the thing they like is some features around. So some nice right angle corners definitely help for image tracking stuff
golden snow
Yea, they can work outside, if it's not too bright and not in the middle of an open flat field of grass with nothing around to track π

anyone familiar with this collision method from this youtube tutorial? https://www.youtube.com/watch?v=XeRv8sb1sdM it's done in blueprint, but I'm trying to recreate it in C++. As far as I can tell, I've recreated the calculations he does in blueprint, but for some reason my capsule is still offset from my HMD and VRRoot. The hierarchy is slightly different there is a scenecomponent as root, then the VRRoot and Capsule are attached to the root separately. I've got this C++ Code:
FVector DevicePosition;
GEngine->XRSystem->GetCurrentPose(IXRTrackingSystem::HMDDeviceId, DeviceRotation, DevicePosition);
DevicePosition.Z = 0;
FVector NewCameraOffset = DevicePosition - LastCameraPosition;
GetCapsuleComponent()->AddWorldOffset(NewCameraOffset);
LastCameraPosition = DevicePosition;
GetCapsuleComponent()->SetWorldRotation(FRotator(0.f, 0.f, 0.f));
DevicePosition.Z = GetCapsuleComponent()->GetScaledCapsuleHalfHeight();
CharacterRoot->SetWorldLocation(GetCapsuleComponent()->GetComponentLocation() - DevicePosition);```
Which seems to match the calculations in the video
These are screenshots of the two calculations I'm recreating.
but I'm ending up in game with the capsule off-set like this. In the video example, the capsule is right on top of the HMD.
tired tree
@jaunty shell yeah I think the physics settings just need some tweaks is all, its not the most stable with defaults.
but in general, everything works fine

or turn on WalkingOverride

Anyone using the Vive Focus+ and having trouble with the floor calibration? I set the eye height to 180 ( as in the documentation ), but when in my app I can touch the ceiling... Anyone had this experience or know how to fix it? I can't find anything on re-calibration ( should do it automatically )
quaint frost
Hi, just a quick question. If I was to use dual Graphics cards.. Could I use one for the HMD while the other rendered the view onto another screen? or does the single card render both HMD & Screen view?
ATM I only have one card but if I could improve the performance of rendering to both HMD and external screen with two cards that would be cool.
tired tree
@quaint frost the preview? or a second player at the PC? because the preview isn't "rendered", its blted from the VR buffer
quaint frost
ah... so if I was to use a screen to demonstrate the view of the user in VR.. it still uses the same graphics card... sorry about this, still trying to understand if rendering to both HMD screens together with an external screen will impact the VR performance.. I was hoping the second graphics card could deal with the external screen.. freeing up the first card for the two HMD screens... or something like that..
tired tree
it doesn't render the preview
its a section of what is rendered for the headset just displayed
unless you specifically show a custom capture
quaint frost
so it doesn't impact performance?
quaint frost

uploading a recording

@mighty carbon I've been developing for Go since the headset came out, you can drag-and-drop files to the headset. I transfer video and screenshots with Explorer all the time.
Of course, you need adb set up to have the headset detected first.

I still use adb pull, since I am using cmd for deployment to the device anyway
it wasn't working not too long ago, not just for me, as you can gather from the thread I posted

Yeah i mean, it still says 0:00 and i cant play it from the quest in explorer, only moving onto the pc works
Why do you use adb to deploy @mighty carbon , why not just from editor?
mighty carbon
because you won't find some bugs running from the Editor
I had an instance where running from Editor worked fine, but running from installed apk crashed the game
reported to Epic and they finally fixed that

Nice! No wonder that select available frequencies bp doesnt work on the quest
granite jacinth

I wonder if there will be 3-DOF-only products
Or if it would even be allowed
edgy pelican
@mighty carbon Ohhhh. That might explain why I haven't seen the issue. I haven't updated the engine for my project since 4.18. I didn't wanna fix my project with every update, so I forced myself to lock in the engine version to 4.18. Perhaps I chose wisely.
With my luck, I'm most likely handicapping myself from being able to port to Quest easily.
mighty carbon
@edgy pelican that has nothing to do with engine.. It's the update for Oculus Go (Oculus Software/firmware/drivers) that broke video shots (or file system).
and no, you did not chose wisely when it comes to upgrading engine. With UE4 you should really be on current release to take advantage of performance optimizations, SDK updates and bug fixes
when it comes to VR projects at least
edgy pelican
That's weird. The firmware's updated on my Go, and based on what I've researched of game dev projects, there's a time you should really lock down your project's version.
But, I get what ya mean about updating for VR. It's a different monster than a PC or console.
tawdry dragon
Basically you could just try test builds of your projects with each new engine update
thats what I do with our VR projects
edgy pelican
@mighty carbon You've certainly brought up some good questions to answer regarding my project. I'll certainly look into how the updates will affect the overall performance for Go. And if that fails, I'll go with @tawdry dragon 's suggestion and move on up.
tawdry dragon
if you want to go with the Quest or go
you should really be using Oculus branch of UE
Atleast that's what everyone keeps telling me
edgy pelican
I didn't go with the "compile yourself" version. I went with the very basic stock instructions that came with Oculus and went from there. I didn't wanna muck it up.
mighty carbon
the latest Oculus branch π
tawdry dragon
Its not that hard Tomio π
and you cant really fuck it up that much... As soon as the engine is build you're good to go
edgy pelican
When it comes to grades and school projects, I prefer to be sure.
tawdry dragon
understandable, but you should really try it out π It's a bit scary the first time but after thats its a easy peasy
I have zero or next to no c++ experience and I did my first custom builds of the engine a few weeks in
to fix the SteamVR mirror
edgy pelican
There're people that are out there in the front, experimenting with unstable things to make them stable. I'm not that person.
tawdry dragon
Theres a difference in using unstable builds and building stable releases π
edgy pelican
There's a stable release, and there's a release with full documentation, support, and community documentation.
tawdry dragon
Im literally building the Oculus branch on my 30 minute old formated PC as we speak π
edgy pelican
I move at that crawl where I have full support.
I'd love to jump out in front and mess around with no help, but I can't afford that atm.
tawdry dragon
You have the people in this channel in case it goes sideways
pretty helpful community here π
edgy pelican
Totally. This is actually the most I've said on this channel in 3 years.
Could be 2. I lost count.
tawdry dragon
Anyways, its ofcouse completly up to you. But I urge you to try it out when you have an hour to spare π
edgy pelican
I will, when my plan breaks. And if it does, then I'll be right up there with the rest of you folks.
tawdry dragon
Are Oculus actually doing changes to the UE4 source or are they "just" updating their plugins in the branch?

@sturdy coral you mean for Intel Dedicated GPUs next year?
I just hope that they can unify it in someway
Perhaps under OpenXR
I rather not have to integrate everyone's "VRWorks" SDK to get the benefits

Gen11 is for their OnCPU IceLake stuff though

@granite jacinth the VRS on directx 12 is even hax-ier than the Nvidia extension
the nvidia extension is strictly only screenspace tiles
but the VRS on dx12 has per-drawcall and per-triangle VRS settings
thats what they use in civ
they have the drawcalls for the cities on the high res setting, and the drawcall for the sea on low

just double click onthe Custom Event name and rename it to Pickup
oh it's using an interface with a pickup method

just implement the pickup actor interface into your new blueprint

@hallow knoll any plans for any new training VR streams soon ? π
hallow knoll
@sturdy coral I've been thinking about doing what you suggested with some of the training tutorials that's being produced. A few weeks after it goes live, I'd like to do a live Q&A for those who's had a chance to go through the tutorial
@mighty carbon Since there's been a lot of good resources for Quest, I'm thinking of doing an Index stream on how to set up the controllers and how to use Steams controller bindings
mighty carbon
oh.. when did Epic have stream for Quest ?
hallow knoll
We haven't done a stream on Quest, but an Oculus rep did a deep dive in one of our UFE videos. That + current docs covers much more than I'd be able to do on a stream
mighty carbon
oh, I see
hallow knoll
There's a lot of good information in that talk
@mighty carbon As much as I love VR, there are more "regular" developers out there. Trying to find a good balance and the right guests so that it caters to everyone.
I'd recommend filling out the survey after you've watched the stream, there's a part of the form where you can request content π
ember forum
will the index livestream feature champagne
hallow knoll
Ah, haha
It's steep for sure, hopefully it'll go down at some point
$500 for the HMD is not bad though
(if you have a Vive)

oh its 500$... i thought it was like 900$ something ... that must be another one.. too many hmds out there now
which i guess is a good thing for vr devs
oh i see the kit is 999
https://wiki.unrealengine.com/Command-Line_Arguments_on_Mobile in order to profile live using unreal profiler i need to add that commandline.txt to the root folder of my project... and i pass that file via adb is that correct?

@zealous cobalt my guess here is that your ray gun is attached to your pawn in some way and not actually what youβre controlling, in your player pawn get a reference to your ray gun and then put the fire events in your pawn

So when I grab my raygun, it gets attached to the motion controller. How do I make the motion controller make the ray gun fire?

toxic oracle
@zealous cobalt how much have you done in unreal before?
zealous cobalt
Pretty much nothing
toxic oracle
While VR is an awesome and fun area Iβd really recommend starting in 2D, learning the basics of that then moving to 3D and after you have a bit of experience there then going into VR
zealous cobalt
Yeah, well I have the quest and I am probably going to return that but I want to make a little something first
And isn't UE4's Paper2d thing pretty crappy?
toxic oracle
Not really and for an absolute beginner itβs a great place to not have to worry about assets or lighting and just being able to focus on the programming
With doing VR development as your learning point youβre slowing down the speed at which you can learn and fail at, especially on the quest where deploying to it takes a few minutes
Youβll save yourself a lot of hassle and questions if you explore 2D and flat 3D first to learn the basics then come back to VR
zealous cobalt
Yeah, I noticed that for sure. But like I said I am not going to have vr soon so I want to have a little fun/anger now. Well another noob question how do I make the it check that a ray gun is attatched so the hand does not shoot lazers?
toxic oracle
When you pick up your laser gun save that as a variable then when you take the player input on the pawn, check if the laser gun variable is valid and if it is call a function on it to fire
zealous cobalt
Ok thanks
When I grab my gun, I have a Boolean get set to true. How can I make another blueprint access that boolean?
zealous cobalt
@toxic oracle Sorry to bug you, I know I am out of my league here, but if you help me with this I will stop working on VR stuff. After the ray gun gets picked up, I have a boolean get set to true. After that I have no idea what to do
That is in the BP_RayGun
toxic oracle
To get the Boolean variable you can do some like get player pawn then cast to your pawn and then you can get the variable from there @zealous cobalt
Did you watch that live training I linked on blueprint communication? It should be covered on that
zealous cobalt
I got it. Thanks for the help

Migrated BP_CommentaryBox into my VR project. it doesn't trigger with my VR pawn. help?
im talking about this
it has proximity range and pops up when pawn overlaps. not triggering with my VRPawn
(I migrated it from the Architecture Vis example project by epic)
woeful sundial
@dim imp check the part where the overlap event fires. does it cast to a ArchVis Character? if so, change the casting to pawn or more specific to your vr pawn. (i'm not familiar with the Architecture Vis example project).
dim imp
@woeful sundial
this is the place. but there's no reference for any character at all, so I think it should work
my vr character is a pawn
woeful sundial
i see... so then i would put a print string after those events to see if they execute. maybe that bool "preview mode" is set to true.
next would be to check the collision settings for the trigger and the vr pawn. make sure they are not set to "ignore" each other.
and also check in the vr pawn "generate overlap events" in the collision settings.

Hello. How can I get Bloom and color grading to work inside PP without enabling mobile HDR? I'm developing for Quest. The Documentation recommends to disable mobile HDR for better performance though. I would appreciate some advice. Thanks!
woeful sundial
@real needle think about it for a second, if there was a cheaper method for bloom, wouldn't everyone use this on all kinds of hardware for better performance?
if it is important to you, enable it. then you have to cut somewhere else.
(but beware, post processing effects in vr feel different from look at a screen. these are often not recommended not only because of performance, but also they might give a bad experience.)
at least color grading is something you could do to your materials. bake the color changes in to your textures to give it your desired look.
real needle
Thanks for your advice, @woeful sundial !
woeful sundial
@real needle good luck! π
real needle
@woeful sundial baking effects into material makes sense to me.
woeful sundial
if you have textures in your material. those are 2d-image files from photoshop or substance painter (psd, png, tiff, jpeg..). change the color grading on those for example in photoshop and save them with these changes applied. so you applied color changes beforehand, so that your game does not have to process color grading during runtime.

true ledge
So, still trying to figure out how I can register a punch in VR, I currently have the force direction, (I think, see BP below.) but I know need to figure out how to check if the player is punching, if they are then set a trigger off. Any ideas from anyone?
wicked oak
@mighty carbon software culling works super well when you do the colliders yourself
a team i know that is ridiculously high end, porting their PSVR game to Quest, is using ti
what they have done is to just build a occluder for the entire level
so they have a very low poly mesh as occluder for every level, and thats it
it gives them super good culling on very low cpu usage, as that occluder is only 1 occluder to render
elfin edge
@true ledge If you are talking about registering a punch vs a move, you have the velocity length in your blueprint already. If velocity greater than punch speed, it's a punch. (Be ready to counter a lot of edge cases - as it's not that simple in general)
true ledge
So I just need to figure out a good speed for a punch that all users can use? Punching isnt actually a mechanic in my game its literally a trigger off another mechanic. So I don't think it should need much tuning@elfin edge
elfin edge
@true ledge Yeah, I'd advise slinging a text renderer on your hand BP and outputting the velocity to that so you can see the values in realtime
mighty carbon
@wicked oak yep, it worked well in 4.21.2, not the case anymore in 4.22.2

Not really a dev question more of design but lets say the player has an object in their hand that can only go one way. To throw this object the player has to punch their hand forward with the motion controller. What would be the best way to give the player more precision?
jaunty shell
@mighty carbon the "Free Fantasy Weapon Sample Pack" if you wanna check
oldschool but works well for mobile
tired tree
@jaunty shell its more likely the shear number of overlapping spline components that make it so heavy with transparency, you are looking through dozens of mesh components when facing the end of the thing.

it would be one thing if you just couldn't get on there store but could sell on others like itch or something.. but they pretty much block all that by requiring the dev sign up for sideload
pearl tangle
well you do run that risk by wanting to sell something on somebody elses platform. Steam was the same not all that long ago and Epic store is like that too. Nothing really stopping these guys from selling on steam instead since it seems like its just been low quality graphics used to make it run on quest

Anyone using ikinema for their VR bodies?
Having so much trouble updating to the new version
sonic lake
Hi there! Can someone please help me get few facts about the Oculus Quest straight?
- Having more devices in a single room works fine (no cross-tracking occurs).
- There is currently no co-presence support built into the Oculus API's, but they are working on it. Availability date is still unknown though.
- UE4 multi-player (on a LAN) works with the Quest, so this may help to address co-presence until the native API becomes available.
Is this an accurate summary of the current state?
- If Oculus doesn't like your game, it won't be published on their platform (courtesy of @sturdy coral)
pearl tangle
- should be fine
their co-presence probably allows for some shared space understanding for initialization, but you can do that yourself without too much of an issue. Just get people to start in a specific spot in real life and go from there - It's the same as any other 1. Play store, app store, steam, EGS everything except for steam now requires some approval process to be available on their store
sonic lake
@pearl tangle thanks, appreciated! Did you try UE4 multi player with the Quest?
pearl tangle
nope i only have 1 quest, but i have done share space AR stuff before so it's likely going to be using a fairly similar technique to the cloud anchor type stuff in that
sonic lake
@pearl tangle thanks again! It is amazing how little info is available also on the dedicated dev forums.
pearl tangle
well the hardware did only just come out
jaunty shell
@sonic lake multiple users in the same room actually works really well
sonic lake
@jaunty shell great! Did you experience multi player as well as a way to implement co-location?
I have seen a couple of demos on YouTube but they seem WIP's
jaunty shell
we did a game of scramble sports or whatever it is
thats as far we went π
havent made anything multiplayer yet on it
sonic lake
We got an RFP for a multi player experience but I think it is a bit too early given the fact the co-location api is not yet released (nor it is clear when it will be)
tired tree
Just manually merge spaces, its not the hardest thing
sonic lake
@tired tree true that, I am trying to figure out how much needs to be done manually and how much is available out of the box. Can you please remind me if your VRE runs on Quest as well?
jaunty shell
@sonic lake if you mean the VR Expansion Plugin, yeah totally, thats what I used for my projects on the Quest
here's yesterday's work using VRExp
tired tree
@sonic lake well none of it is available out of the box for syncing spaces
but as long as you have some sort of position/rotation that you can obtain in each space that is fairly precise, its not that hard to sync
sonic lake
@tired tree indeed, I can map one space to the other based on a initial position/rotation and from there through their respective transformations. I was also thinking to use invisible synch objects in the scene to correct any drift that may occur (sort of triangulation between the players). As out of the box I was referring to the co-location API Oculus is supposedly working on, but I only found it mentioned in an unofficial post.
@jaunty shell looks good! Are you happy with the tracking/responsiveness of the system?
tired tree
how would objects correct for drift? the player is sending their state to the server
without real world syncs that wouldn't do anything
jaunty shell
yeah its quite responsive, very little tracking drift or loss (sometimes for the controllers when they get out of the tracking frustrum obviously)
I've had mild results with guardian recognition from one place to another (worked well with big spaces, in my office I dont need to recalibrate it, build, push, fit the HMD on my head, get up and test)
tired tree
yeah it doesn't always remember spaces
strangely enough my wide open floor basement with good border features is never remembered
while my living room that is constantly different is
sonic lake
@tired tree the idea (to be verified) is that the server keeps a representation of the space with the position of all the players. It also receives from the player their view of the synch objects. Each synch object should be in the same position for all the players. If not, the difference can be used to reposition a player so its space matches with the sever representation and with all the other players.
tired tree
@sonic lake you are talking about in game objects though right?
sonic lake
Yes
tired tree
that wouldn't do anything then...
you would have to set up the forward facing of each space exactly for that to work
sonic lake
They will drift with the player indeed
And a physical object visible with pass through?
tired tree
and even then, that wouldn't make a difference unless you constantly had them hit the same spot
as the player is telling the server their view
I don't think drift is much of an issue tbh
you'd be better off focusing on initial calibration and alignment, and then if drift becomes an issue then you address it
sonic lake
Ok so I can assume that with a good initial calibration the spaces will match from there on
Playtime is supposed to be 30 minutes
tired tree
i would worry about the forward facing being changed by the user more tbh
but they would have to manually do that
tired tree
I'm curious how quest handles forward facing actually
if its initial guardian setup facing
or some other means
sonic lake
I have to admit we are still waiting for ours so I didn't try that
Supposing there is a forward direction during the initial setup what happens if you move to a different space?
sonic lake
Ok so if I have to match a physical space the Forward should be set identically each time
Otherwise people will run into walls
tired tree
not really
you still have guardian
you can likely manually sync things by drawing perfectly
but if you have an offset space, some place to put a controller or something in a set orientation would allow you to rotate the initial position of the player
and move them
to align
sonic lake
Like having a calibration cradle
sonic lake
Where you place all controllers at the start and calibrate them all
tired tree
and then rotate to match yaw and move to offset to position by the controller difference to the expected cradle
sonic lake
That would actually work yes!
sonic lake
Indeed.cAfter which the cradle can be moved away to clear the space
tired tree
doesn't "have" to be a cradle
could just be a marking
if its outlined well enough to fit the same or at least very close to the same
you wouldn't want to use locomotion of any sort obviously, game would have to be static room, like room to room or sliding all players together / teleporting them
sonic lake
But it has to be in proximity of the quests, cannot be too distant
Absolutely. This would all be room scale.
No teleporting/locomotion.
Sort of cooperative arena game.
Major concern is not having players run into each other.
tired tree
if it has any sort of arm swing mechanics
might want to record maximum arm extent
and throw warnings when players are within that

how about switching to camera view when players are way too close to eachother IRL ? π

the camera view stereo offset really messes with my depth perception, they tried to align it, but its far enough off that its very disorienting
jaunty shell
yeah its whack
tired tree
honestly, I like quest alot, but its not a headset I could be in for hours without annoyance, even just in games it has some weird disorientation
jaunty shell
stereo is too short/wide
tired tree
can't imaging rift S being the same and a desktop one, can take it with the quest since its stand alone
i'm glad I set the network quantization for hmds and controllers to something crazy like 419 meters
football field co-op play sounds dreamy

Hey @tired tree getting knuckles tomorrow! Been reading your docs which are great. Trying to wrap my head around how/if to redo gripping with them. Do you recommend leaving it as a binary interaction based on gesture etc? Physics would be preferable but the idea of getting it to a place where picking up an object with just friction seems daunting.
tired tree
if you are trying to pick up just with friction you will need to run simulated bones
and set grip limits
don't think anyone does frication based gripping since its unreliable and prone to issues
you can handle the pinch input and the finger "grip" input for gripping
the grip can be a scaler 0-1 for force and you can manage off of that
i think for things like guns players will still prefer toggle more than a hard hold though
feral bloom
Ah alright, thanks. So boneworks are probably doing what you describe with a gesture grip and a scalar force?
tired tree
@feral bloom boneworks are using forces and snapping the hand mesh to the object
they are most definitely not using actual friction
blade and sorcery does much the same
in fact some of their mechanics look....really?....close to each other, the hand reposition in dual grip mode is nearly exact from preview videos
dunno if they correspond or not
feral bloom
They are both really impressive looking, your explanation makes a lot of sense to me
tired tree
I think they are literally using force based joints in unity
its like a ue4 constraint with the type set to force and not acceleration.
feral bloom
Is that similar then to the force constraints you showed off recently?
feral bloom
Makes me want to make a melee game
I'm going to be trying to implement the knuckles skeletal module into my full body vr ikinema rig. It's mentioned as possible in your notes but has anyone you know of done it?
tired tree
yes
feral bloom
awesome
feral bloom
Oh very nice
tired tree
I would be curious to see someone actually incorporate the full steamVR skeleton or at least weight the knuckles to the hand mesh properly in a UE4 skeletal mesh
hallow knoll
@tired tree Quest will set your transform to PlayerStart when you launch the game
If you reset it'll move you to player start
hallow knoll
Yes
hallow knoll
Works great for shared space, all you need for a good rough calibration
hallow knoll
I haven't noticed drift between players for 15min play sessions
tired tree
considering that it is taking room features into account
it should be correcting for drift itself
sonic lake
@hallow knoll did you try if with multiplayer the respective spaces stay aligned over time?
Provided they are aligned at the beginning
hallow knoll
@sonic lake Yes that's exactly what my project is π
sonic lake
@hallow knoll Great! I am looking at 30 minutes game play, but the stability over 15 minutes should already be a good indication.
hallow knoll
I have no reason to believe it shouldn't stay synced
Main issue I've come across is if you take the headset off, it will recalibrate when you put it back on
sonic lake
We were discussing earlier with @tired tree the initial calibration to align the spaces for the different players.
Ok, so if there is an initial calibration by putting the controllers on a fixed cradle or something and you take the HMD off you will have to go to the cradle, reposition the controller and calibrate again.
Not 100% ideal.
I guess the recalibration is triggered by the Oculus SDK, no way to avoid it.

Hi has anyone tried out the new HoloLens branch? would be nice to have someone to try to problem solve it with. Here is the link of what I'm talking about:
https://www.unrealengine.com/en-US/blog/unreal-engine-4-support-for-hololens-2-released-in-early-access
hallow knoll
Yeah, I don't think there's a way to override it. You can probably override the proximity sensor putting the HMD to sleep, which would be ideal for a location based experience.
Or you know, tape it ^_^
sonic lake
@hallow knoll as an Electronics Engineer I cannot tape stuff! π
hallow knoll
It works better on rift than doing it in software haha
sonic lake
That fur sure! Speaking out of experience. Bypass proximity sensor in the Debug Tool... nah!
Works 1 time out of 5.
@hallow knoll May I ask what are you using for multiplayer? Are you working on a LAN?
(so latency is not an issue I assume)
sonic lake
@hallow knoll Great, thanks! π
Ok I definitely need to get 2 Quests and try it out
hallow knoll
It's quite magical
I ordered a Rift S for the host PC
Hosting on Quest works OK for 2 players, but any more and you'll start seeing some network latency
sonic lake
I also plan to host on a dedicated PC + another client for a spectator screen
hallow knoll
Yeah that's what I'm doing
sonic lake
Ok maybe I can combine server and spectator view
odd garnet
Hello yes itβs me

FYI for anyone encountering the issue, on Quest with mobile multi view enabled, render targets do not work
Work around is to disable multi view

Hi there! How would I install my Game to Oculus Quest? Any help is appreciated!
granite jacinth
short laurel
real needle
Thank you. But is there any way to install the .apk file directly on the device?
The loading times are very long, If I build from UE4 and then try to launch on Quest.
short laurel
I dont have a quest so I am not sure. On IOS, packaging always takes a long time, and code-signing to deploy manually is a bigger nightmare. Not sure how quest handles that.
I wont waste your time complaining about Xbox or PS4 packaging times....
real needle
Thank you @short laurel Itβs frustrating π
pearl tangle
thats mobile development. No way to stream onto quest yet
although feel free to modify the hololens remote 1 to make it work for quest and I will pay you at least $3.50 for that
@hallow knoll So you need to have a headset running on the desktop machine to let it act as the host?
hallow knoll
@pearl tangle No, not necessary
I have a flat pawn that I can play with
I can run dedicated as well
pearl tangle
so whats the reason for the rift S to act as the server?
pearl tangle
oh nice
anybody happen to have a simple material that changes colour the further away it is from a set point?
doing some funky stuff with the quest at the moment as well. Visualizing elevator vibrations in VR π a few million data points is actually pretty cool to be able to walk around VR in
at the moment just got them as instanced meshes, plan to change it to a particle system later but this is quicker for me to just work directly with a CSV. Just want to highlight the outliers a bit easier
glossy agate
Donβt have a material but you could start with this tut and figure out the distance part. https://youtu.be/sf3jT12pN6o
Ah wait I think itβs just for camera
pearl tangle
yeah i need to define a world position for it essentially. Or from 0,0,0 also works
at the moment trying to trim down the number in the instances by removing very similar 1s from rendering
pearl tangle
hah now running into loops that have too many iterations..
10 million iterations in a loop seems to be as high as you can go
toxic oracle
I think thereβs a setting to change max loop count
pearl tangle
yep can push it up from 1 mill to 10 mill
toxic oracle
Ah gotcha, there goes my plan to make an asteroid field with 10 million and 1 asteroids
pearl tangle
well you can run a loop and then run another loop
I am trying to step through my 1.6million and remove any duplicates or 1's that are overlapping, which essentially means going through 1.6mill x 1.6mill
even my smallest dataset of 4.5k would need a 20million loop
granite jacinth
TBH, if you reach the default loop iteration max...you're probably doing something wrong
glossy agate
You probably have to normalize it like a dist plot in python. Think you can run python in ue4 or you can set the data up first then send it in once you have a cleaned version
Or may have been histogram you can set segmentation amounts to keep the data manageable. Itβs all copy paste script pretty much https://mode.com/python-tutorial/python-histograms-boxplots-and-distributions/
pearl tangle
@granite jacinth I am plotting data from some accelerometers. capturing about 500k data points per day, so just showing a couple of days from the data table hits the default max
@glossy agate I can definitely do the clean up beforehand, was just trying it from the data table first since it manages to perform quite decently with the dataset somehow which is just a straight export from BigQuery. I am going to try doing similar 1 with realtime stuff out of firebase for different visualizations but I have already modified the IOT sensors to only ping me data when there is a relevant change now instead of constant data
surprising at how easy it was to do some quite useful visualization in unreal though
This is actually super easy to pick out the issues with (I just did some quick scaling to try see the outliers easier). But trying to get some insight like that from a 2D x,Y scatter plot is very tough
glossy agate
Yeah thatβs def badass. Tons uses especially with being able to real time it all in 3D
You actually can access the firebase db in real-time through ue4 already? You have a guide for c++ for ue4?
pearl tangle
yeah the crazy part is that I was actually able to build a 3D working duplicate of an elevator that is a digital twin of the real 1s, display it in AR in the hololens faster than I could build a web dashboard to show it these days...
jaunty shell
@granite jacinth that tut', good stuff !
pearl tangle
I use the firebase plugin. @rapid comet has some pretty good plugins, although it doesn't handle firestore yet so I am doing some data duplication into the realtime database (older firebase db) at the moment for the basic info to show there. Which is just the current position of the lift, doors etc, not the more complex telemetry
glossy agate
Thatβs awesome man. I have only used it for user auth and only with js. havnt looked at the c++ yet cause Iβm trash at it and I hadnβt thought of what to do with it
pearl tangle
I run firebase for leaderboards and dashboards etc all the time
and then you also have firebase analytics in there as well now rather than running GA
depending on your project too I also use it quite a lot for live updating variables and changing stuff around on the fly, especially with mobile development
glossy agate
Nice. I saw the unity logo but never even crossed my mind for ue4 π. Iβm the last one to know you could do it I guess.
Iβm interested in the data science stuff you can do now
Iβve just been writing finance stuff lately not games. Thereβs something I could do with this
pearl tangle
yeah they have a direct plugin for unity, unreal you can build yourself with the c++ sdk or just use gamedna's plugin which works fairly well. the ultimate mobile kit plugin as well you can then use for the push notifications and deep linking etc
unreal is a lot more fun for visualizing stuff than excel or matlab, so should work alright with finance stuff too if you feel the need to look at it in an Oculus Quest for whatever reason hah
glossy agate
For market segmentation stuff like on a map looking for opportunity areas for investment/advertising . My other app parses property data and gives deep insights on a house like value rent potential current equity position ect through an api through places like core logic.
Can plot places that appear to have a high opportunity for growth. And places that have a high chance of wanting a refinance after an appreciation spurt with increased equity positions
If you are interested in doing real estate data check out estated. Com. They are way cheaper than any other provider for end points and has decent coverage. You could def come up with something cool
pearl tangle
sounds quite interesting. Might be a task for another day. At the moment I have designed and built a bunch of sensors for smart building stuff, so doing the digital twin part with unreal which is more fun than building the web and mobile versions hah
tired tree
@pearl tangle you can "unwind" the loop and step through multiple at a time instead of 1 per, but sounds like the perfect thing to have a small c++ function to replace the implementation.

Can someone help with textbox focus not working in vr oculus go?

@pearl tangle Please note Firebase Realtime Database has also advantages over Firestore cause Realtime Database is for example faster...
tacit quest
Hey, what are you guys doing for camera fading on the quest? the built-in camera fade doesn't work without mobile HDR
also i seem to be getting occasional crashes that i'm pretty sure are physics/collision, wondering if anyone else seeing the same thing
wicked oak
@pearl tangle literally a couple days ago i made a C++ "script" to do data analysis
did you know C++17 has filesystem support? you can use that to create a script that grabs all the files in a folder, and if they have a specific file type they do something
for a plot system like that, i would use software rendering (no joke)
grab SDL, make a 2d array of ints as pixel colors, and plot each of the point into a pixel. That pixel gets +N in colors from the point
should be able to make it chug along with tens of millions of points just fine
pearl tangle
yeah i was going to go with point cloud setup for it, I did some stuff with that in unreal before and it handled a several million cloud pretty easily. Just need to convert the data into a texture map
wicked oak
btw im so happy C++ now has parallel STL + filesystem
making stuff that processes files in parallel is super trivial now
only thing it lacks is a proper multithread queue
pearl tangle
@tired tree Definitely blueprint implementation is not the ideal setup for it, but I was still quite impressed what I could get going in a very quick afternoon just after having installed the sensor. Built 30 more sensors now to start getting some interesting data sets
you would think by now they would be doing some more optimization around threading side of things for it
pearl tangle
not blueprint. C++
actually I saw somebody had done a multithreaded implementation of blueprint somewhere too
tired tree
you can call blueprint functions to threads in c++ just fine
you just can't put them into execution chains
has to have a latent return
