@tired tree , I was checking the BasePass Geometry render time, but yea I will check that next time I head in, that's a good idea

sturdy canyon Nov 9, 2018, 1:28 AM

#

BasePass Geometry should be unchanged

sturdy coral Nov 9, 2018, 1:28 AM

#

geometry render time may even go up since the culling is less precise

sturdy canyon Nov 9, 2018, 1:29 AM

#

what should be changed is HZB downsampling on the GPU should be cut in half and and those 16 draw calls should reduce to 8

#

or whatever

chilly ocean Nov 9, 2018, 1:29 AM

#

Gotcha, will look at it when I get in the lab next time. Thanks guys!

sturdy coral Nov 9, 2018, 1:29 AM

#

I think it is for hardware occlusion queries (non-hzb), but I'm not sure

#

or maybe both

sturdy canyon Nov 9, 2018, 1:29 AM

#

ohhhh

#

maybe..

#

I thought hardware occlusion was HZB?

sturdy coral Nov 9, 2018, 1:31 AM

#

they are a separate thing, older than HZB as a technique

#

I think it basically draws a bunch of quads based on bounding boxes or bounding spheres and tests them against depth the depth buffer

#

it disables write to the depth buffer before drawing them, and the gpu reports back if any pixels would have passed the depth reject and been written

sturdy canyon Nov 9, 2018, 1:32 AM

#

oooh HZB mips was reduced to only 2 draw calls per eye anyway

sturdy coral Nov 9, 2018, 1:33 AM

#

they say HZB can result in less precise culling and result in more draw calls/geo work than regular occlusion culling, but I'm not sure why

#

I would have thought the two would be equivalent

#

occlusion queries are just a brute force search, and HZB is sort of a quad tree optimization on it

sturdy canyon Nov 9, 2018, 1:34 AM

#

How do I select between the two?

sturdy coral Nov 9, 2018, 1:35 AM

#

it is in the renderer settings somewhere

sturdy canyon Nov 9, 2018, 1:35 AM

#

I can't find the checkbox 😛

sturdy coral Nov 9, 2018, 1:35 AM

#

screenspace reflections and ssao will force it on

#

at least the HZB generation, maybe not theHZB occlusion testing

#

because those two use the HZB structure in their ray tracing

sturdy canyon Nov 9, 2018, 1:38 AM

#

I'm surprised SSAO uses the same structure.. HZB uses a max filter instead of average

#

I think it should let in too much light for SSAO

#

maybe it's good enough and not worth spending time on the extra downsampling, though

sturdy coral Nov 9, 2018, 1:39 AM

#

@sturdy canyon I don't see it in renderer settings anymore either, even in 4.20

#

r.HZBOcclusion is the console variable

#

they may automatically pick it or something now

sturdy canyon Nov 9, 2018, 1:40 AM

#

I'm using SSAO, so it sounds like round robin occlusion won't even help me 😦

#

will help on PSVR, though

#

@sturdy canyon if HZB lets more stuff through but doesn't require many draw calls, seems like you could do both techniques, HZB as first pass, then hardware occlusion culling on anything that made it through

#

anyone messed with this? how do you turn on the debug canvas?

#

New: Added a composite debug canvas layer to Spectator Screen:

The debug canvas layer is now copied onto the spectator screen if both of those features are active.
The layer is mapped onto the spectator screen with letterboxing, so its aspect ratio will be preserved but additional unused screen space may exist (usually on the left and right).
The layer resolution is unlikely to match screen resolution so the display is expected to be somewhat fuzzier than normal.
Spectator modes that use API level support for mirroring to monitor rather than the SpectatorScreenController will continue to function as before where they do the monitor mirroring after the debug UI is drawn so it will appear but may be cropped oddly.

Would making swipe inputs for Oculus GO be the same as doing it for GearVR?

granite jacinth Nov 9, 2018, 2:32 AM

#

@languid night should be

sturdy canyon Nov 9, 2018, 2:33 AM

#

Yeah we don't change our input manager at all for Go and GearVR

languid night Nov 9, 2018, 2:35 AM

#

Ah, then that makes sense.

#

In order for swipe input to work, do I need to have a touch interface setup?

sturdy canyon Nov 9, 2018, 3:02 AM

#

I just sample the motion controller x/y axis on tick on my input manager

#

Swipe detection code had a small trick on it where I only accumulate into the x or y swipe accumulation buffer if the x travel is more than twice as big as the y travel

#

That way it never accidentally triggers a vertical swipe while horizontal swiping

languid night Nov 9, 2018, 3:11 AM

#

I see. Thanks a lot @sturdy canyon

languid night Nov 9, 2018, 3:33 AM

#

@sturdy canyon For the swipes, do you use thumbstick input or do you use touch input from the Oculus Go controller?

sturdy canyon Nov 9, 2018, 3:43 AM

#

I use the event motion controller L X Axis or maybe right X Axis

#

I think you have to switch based on handedness?

#

On one of the platform you have to switch based on handedness

languid night Nov 9, 2018, 3:47 AM

#

Yeah, it does depend on handiness for the Go. Anyways, thanks again! I'm on the right track.

@sturdy coral nah, next plans they are selling to HTC ;P

sturdy coral Nov 10, 2018, 2:07 AM

#

I think there is a good chance it is a reference design since they had that call for partners and were going to be providing the lens, tracking, and LCD driver technology

#

and combining lighthouse + insideout would make a lot more sense if knuckles had LEDs on it.. which it doesn't (and seems close to final)

granite jacinth Nov 10, 2018, 5:41 AM

#

@tired tree @sturdy coral they won't sell to others

#

This is going to be their baby if it's true

#

The issue will be pricing it right for consumers

#

They have to go on a certain offensive since Discord is taking some of their money and players (just a bit)

#

If they are going to conquer some market (other than digital store), might as well be the one where they have a good chance to make a difference

also becouse they are losing money per sale, and need to recoup through their store, if you use it on pc, you might just buy the games on steam

tawdry dragon Nov 11, 2018, 6:30 PM

#

Anyone ever played with doing latency calibration with openvr? Issue I'm having is that I'm using a vive tracker to 3d track a real camera while the media bundle plugins feeds in video. However there is a slight delay from camera movement to the video input getting displayed in the engine, so that means the vive trackers transforms are off. I'm wondering how to go about aligning them

sly elk Nov 11, 2018, 6:48 PM

#

the individual finger tracking + using that info to do a grab system

#

also, just from a theoretical standpoint, what is the criteria to define a successful grab? Two points of contact that must be facing each other within a certain tolerance?

tired tree Nov 11, 2018, 6:58 PM

#

@sly elk well there are still the finger curl values

#

you can sample that to get extent of curl, but if you wanted what they showed in their skeletal tracking demo, it takes a bit more effort currently, as the engine is actually broken for supporting it atm

#

as far as grabbing, you can specify overlap points on the hand yeah and consider it a grip when opposing fingers grasp something, usually thumb + any other digit

sly elk Nov 11, 2018, 6:59 PM

#

I don't have super accurate collision volumes on my parts, would have to do complex collision

tired tree Nov 11, 2018, 7:00 PM

#

their startup demo just binds to the "grip" action which is all of the primary fingers down and the amount down thye are

#

for per finger tracking you can manage it with curl values, but the full skeletal API is far more useful, I would imagine even more so for your game, as the gloved hand approach fits it perfectly

sly elk Nov 11, 2018, 7:01 PM

#

i haven;t look at knuckles much in depth. If you want to do a simple/dumb grab system with them is there an easy input for that?

#

like totally ignoring finger tracking?

tired tree Nov 11, 2018, 7:01 PM

#

yeah, pinch and grip

#

they also still have normal buttons

#

pinch is trigger + thumb down at the same time, grip is the 4 primary fingers curled down

sly elk Nov 11, 2018, 7:01 PM

#

cool. Wrench has lots of tiny parts and if they are actually in your hands its easy to have controllers bash together before you get them in position

which is why we don't snap anything to hands

Especially with the lack of UE4 support currently

We just need Valve to pay Epic to build a short knuckles based platform exclusive so they have an incentive to implement everything in vanilla unreal

tired tree Nov 12, 2018, 8:41 PM

@sly elk valve is working WITH epic on integrating it

its just harder in ue4 than unity

since everything is more static layout wise

sly elk Nov 12, 2018, 8:43 PM

oh nice.. When I talked to someone from valve a few weeks ago it sounded like unreal users were going to have to do it from scratch

#

Is there news on that or an expected timeline?

tired tree Nov 12, 2018, 8:45 PM

#

"post 4.21 release in the dev branch"

#

it likely won't have everything

but just not locking out skeletal actions would be enough to make the rest really easy

can do it currently with some workarounds for testing, but its less than ideal

@digital musk enable hmd doesn't block reading from sensors - theoretically

on the other hand some states/events might not be available to all hmds

I think you have to use use GEngine->XRSystem->GetStereoRenderingDevice()->EnableStereo(true/false);; disabling hmd/vr instead might interfere

Hi there, I want to pack a ue4 project so the client can use it with VR steam, but I don't use VR steam so my question is it possible to pack ue4 project to be used with VR steam without having one and if yes what steps should I follow?

cosmic shoal Nov 16, 2018, 12:47 PM

#

@elfin notch for Vive and Mixed reality you need SteamVR you don't need a Steam account. you can manage the steamVR distribution on machines with no internet with a tool that HTC has on their site.

elfin notch Nov 16, 2018, 1:35 PM

#

@cosmic shoal Thx for the reply. The problem is I don't have SteamVR device. Can you please elaborate more on the tool that HTC has that can help me? What tool is that and how can I use it?

elfin notch Nov 16, 2018, 2:14 PM

#

@cosmic shoal My first attempt was to pack the project for windows 64 and that I did. I shared with the client but he could't open it at all through the SteamVr. So I'm guessing that I need to do some adjustments on the file before packing so he can open it through Steam VR.

cosmic shoal Nov 16, 2018, 2:26 PM

#

What headset?

#

The tool HTC has is for places that limit internet access so you can deploy steamVR without a network.

#

https://enterprise.vive.com/us/product/dms/ I just found it through a search, dunno if it cost anything.

VIVE Enterprise | Device Management System

#

did you test it locally? I beleive it depends on your unreal version but for some you have to add -vr to the shortcut launch command of the .exe for it to launch in VR.

elfin notch Nov 16, 2018, 2:44 PM

#

@cosmic shoal I can't test i locally as I don't have any VR device/headsets. You mean for exp. namefille-vr.exe?

cosmic shoal Nov 16, 2018, 3:02 PM

#

ok.. developing for VR without a vr headset is pretty crazy, but what I meant is to make a shortcut of the exe, then modify the launch command of the exe.. Like in this picture I'm modifying the exe for blender

📎 unknown.png

#

right click on the shortcut, select properties, then add -vr at the end (a space is required I beleive)

#

in a pinch you can use steamVR with your phone using iVRy

elfin notch Nov 16, 2018, 3:22 PM

#

@cosmic shoal Thank you so much. I will try this. Just one question can I do this and share only the shortcut to the client or this process can be done only on the client pc so it can work.

cosmic shoal Nov 16, 2018, 3:29 PM

#

he can do it

#

the thing with sending him the shortcut is that the path has to be the same

#

he would have to have the exe in the same file structure as you

fleet plume Nov 16, 2018, 5:53 PM

#

i'am throwing an actor and it should generate an event when hitting the floor. i guess "simulation generate hit events" + OnComponentHit is the proper way for that? (compared to regular overlap events)

#

i guess i'am just worrying that regular overlap events on floors would become a drag on performance?

sturdy coral Nov 16, 2018, 6:16 PM

#

@elfin notch if you go to project settings and do 'start in vr' it should do the same as launching with '-vr', so the client wouldn't have to do it

elfin notch Nov 16, 2018, 6:53 PM

#

Yeah you definitely gotta lerp those fingers or something

#

I'm trying to do knuckles Dev today in 4.21 and getting them set up is totally undocumented as far as I've found

#

You have to add vr.SteamVR.EnableInput=True to default engine.ini I think

#

And then you have to set up Steam input bindings and I don't really know what's going on

#

Interestingly there's an event knuckles curl for each finger, but they always return zero

#

And then once you enable steam input, those event nodes become invalid

Ugh. Well, let me know if you have any luck.

@ornate raptor

tired tree Nov 17, 2018, 2:49 AM

#

@sturdy canyon you don't want to enable the new beta input system

#

if you are trying to use skeletal input

#

it overwrites the action manifest every time it loads and that is what you have to define the skeletal actions in

#

ie: the new beta totally breaks the ability to use that part of open input >.<

#

you can't just inject the actions in non engine source builds either, because then the action handles that run inputs are stale and won't work

#

I am sideloading them into the legacy mappings for testing until that is fixed so that all of the normal engine workflow works but testing can still be done

#

also as for the twitchyness, yeah you could lerp them across frames, but you also need to calibrate them a bit by clasping and unclasping your hands a few times when you pick them up

wicked oak Nov 18, 2018, 8:59 AM

#

@sturdy coral something similar, yes

#

a gbuffer that allocates itself

#

and automatic aliasing of the memory

#

so if you have a pass that renders de SSAO, and then you use the SSAO with the lighting pass, you no longer need that SSAO data

#

so a further postprocess pass can just reuse that memory you were using for the SSAO to do other thing

#

it can save a considerable amount of memory in complex projects

they were able to improve memory usage by 40%

thanks to the automated memory management

and it also made the engine far more easy to work with and modify render passes

but maybe one with vr in mind with a menu syste

median wedge Nov 20, 2018, 3:43 AM

#

is there a way to manipulate bones with the motion controllers (ex. gun is skeletal mesh and slide is a bone, and the motion controller can manipulate the slide)?

#

How would I start doing that?

sonic lake Nov 20, 2018, 10:20 AM

#

@median wedge I would add a collision sphere to the gun, close to the slide, then detect the overlap of it with the other hand (the one that is not holding the gun). When the overlap is triggered, you play the reload animation from the skeletal mesh.

median wedge Nov 20, 2018, 12:57 PM

#

@sonic lake I am talking about actually changing the position (while constrained) of the slide. Not playing any animation

sonic lake Nov 20, 2018, 1:00 PM

#

@median wedge Same concept apply. The hand enters the overlap area of the slide. The slide checks the hand is grabbing. The slide starts tracking the hand. It moves following the hand. Eventually the hand releases it and the slide stops tracking it. And it stays in the last position.

median wedge Nov 20, 2018, 1:02 PM

#

Alright, so I just manually adjust the transform when it is tracking the hand or should I use a physics handle?

sonic lake Nov 20, 2018, 1:03 PM

#

I would adjust the transform on Tick.

median wedge Nov 20, 2018, 1:04 PM

Alright. Thank you for your help

its hard because there are only so many buttons on vive

wheat holly Nov 20, 2018, 2:10 PM

#

I've it on the oculus however

#

But what kind of game are you making?

#

Something with a lot of items?

#

Or just a couple

#

Because if you are making for example a shooter, you could do it like Robo Recall where you have 2 guns on your hips and 2 heavy weapons on your back which you can grab and also respawn. You can modify them after each level, and manually say what goes in what slot, and with which attachments. Or you could remove the respawning part and make it so you can put weapons back on your hips / back.

#

Or of course some place else, where ever it fits 😄

sly elk Nov 20, 2018, 2:20 PM

#

Yeah, the forest inventory is intentionally designed to be hard to use during combat

wheat holly Nov 20, 2018, 2:20 PM

#

That's true.

#

A downside of it however, is when standing in front of for example a tree it glitches inside it.

#

I guess it's a pretty solid option when you've large amount of items though

#

If you have not that many items, you perhaps could make some kind of item with the items displayed on that object.

sly elk Nov 20, 2018, 2:22 PM

#

Yeah, it really depends on the game

wheat holly Nov 20, 2018, 2:23 PM

#

Yep

#

I don't really think that VR has 1 solid solution for inventory management in every case.

#

Another solution I saw for a base defend game called Undead Development, was that you as the player could put stuff in your backpack which caused it to spawn the item inside your base when looting outside your base.

#

So you didn't have to carry it all the way to your base and eat up all your time 😉

Enough idea's @quiet swan ? 😄

@dim iron It's very good method. Just make sure your button has Generate Overlap Events set, otherwise it will never trigger the overlap with the VR hand.

dim iron Nov 21, 2018, 1:21 PM

#

@sonic lake I have on the button itself "Generate Overlap Event" ticked. i created my button in blender and imported in then followed that tutorial. in one of the comments 2 other people have issues. I was wondering if its a version issue?

sonic lake Nov 21, 2018, 1:22 PM

#

@dim iron Does your button have a collision volume around it?

dim iron Nov 21, 2018, 1:23 PM

#

@sonic lake, yes it has a simple collision round it

sonic lake Nov 21, 2018, 2:23 PM

#

@dim iron Ok are you using the standard VR hands or something else?

#

Hands also need to generate overlap events

dim iron Nov 21, 2018, 2:24 PM

#

@sonic lake yeah im using the standard VR template, the hand mesh of BP_MotionController also has generate over lap events turned on.

#

are you able to make it work by following what he does.?

sonic lake Nov 21, 2018, 2:25 PM

#

Can you just create a Begin Overlap event in your button and use a Print String to check that it actually fires when the hand overlaps it

#

If that doesn't work, it means something is wrong in your collision setup

Otherwise you’ll probably have a bad time

#

For VR I mean.

#

I know normal Unreal Games run in GTX 970

dim iron Nov 23, 2018, 1:11 PM

#

GTX 970 is classed as the standard for VR, its the entry card for it. You could overload a 1080 ti just like you could the 970, all depends on what you are doing.

#

but yes in general gtx 970 should be ok for VR dev.

real needle Nov 23, 2018, 1:13 PM

Is Unreal more demanding for VR than Unity.

Meaning I'll have to settle for lower everything including map size and polygons etc?

#

I'm worried about choosing the wrong engine since I'm on a low end card

frigid kite Nov 23, 2018, 1:50 PM

#

You can't really generalize how demanding an engine is

#

It's always the responsibility of the developer to optimize the game properly

#

Both engines have plenty of features to support lower end devices

#

Fortnite is a great example for Unreal

#

Unity also has plenty of tools though, such as the lightweight render pipeline

sturdy canyon Nov 23, 2018, 6:11 PM

970 is what I use for SculptrVR

If you want to maximize your market, it's the card I recommend

wicked oak Nov 23, 2018, 7:43 PM

PSVR is fairly legit tho

for a VR indie team

but PSVR has less power than a 970

yeah. seems like a huge pain in the ass and it would need to be set up to work with all the gameplay systems

sturdy canyon Nov 24, 2018, 4:50 PM

#

You can also use the social screen if you have the graphics headroom

#

Or just run at 45fps during capture

sly elk Nov 24, 2018, 5:38 PM

#

running at 45 fps doesn't help. At vr pixel density 2.0 the image is still very soft

#

oh, you are saying run the render target capture at 45 fps. Yeah, i have done that for set up clips in the past. Dolly shots or third person fixed cameras. Attaching a capture to the player head doesn't go well when rendering video at 2560x1400.

sturdy canyon Nov 24, 2018, 5:44 PM

#

In theory is easy to just monitor input every frame including position of head and hands. In practice it doesn't work :-/

#

Or doesn't seem to

#

Maybe if you do everything with the input system and record frame exact everything with integer frames instead of timings..

#

Then you swap out the input system during playback with a playback input faker

#

But that's basically what Sequencer is supposed to be..

I'm too dumb to figure out sequencer, though

Hi peeps! Quick UMG related question.

#

I've created a widget, that's used as an in-game menu, and I'd need it to render on top of everything, eg.: no intersection with meshes.

#

Using a material that disables depth test does the job, but this way the widget loses the ability to interact with. Any thoughts on a solution?

mighty carbon Nov 25, 2018, 4:55 PM

#

@sly elk if you get that hardware capture device and manage to capture good quality content, please let me know which capture device you got 😉

sly elk Nov 25, 2018, 5:09 PM

#

I'm not going to get the capture device. It won't help with sharpness of the hmd mirror image

#

@sturdy coral does disabling the lens mask add blKc borders?

#

I can't find any info on a console command for that.

sturdy coral Nov 25, 2018, 5:54 PM

#

@sly elk it should remove the curved borders on the corners and let you do a more full crop for 16:9 with more of the resolution intact

#

I'll look and see when I am back home if I can find a console command

#

Otherwise with those masks the crop has to be inset more probably cutting out 20-30 degrees of fov

#

you can try running through steamvr and disabling the Oculus plugin too

#

At least at one point oculus via steamvr had no lens mask

#

@sly elk found it, it is 'vr.hiddenareamask' on the console

sly elk Nov 25, 2018, 6:01 PM

#

tahnks

sturdy coral Nov 25, 2018, 6:01 PM

#

you will have to change mirror mode to full or something

#

and crop down in your video software

#

I think to change UE4's crop you have to edit some source stuff

#

@sly elk should be a blueprint node for that, 'SetSpectatorScreenMode'

sly elk Nov 25, 2018, 6:06 PM

#

yeah, i have that in my begin VR utilities

sturdy coral Nov 25, 2018, 6:08 PM

#

you'll need a high enough res monitor for the mirror to show enough res unless you crop in engine

#

Unless monitor res > single eye render target res

sly elk Nov 25, 2018, 7:16 PM

#

Yeah, I'm on a 4k display

#

It would be cool if there was an alternate vr mode that disabled stereo and used a rectilinear projection just for developers to make game footage. It would be super distorted and nauseating to play but probably workable enough to record footage

sturdy canyon Nov 25, 2018, 7:40 PM

#

You can just wear a headset like a hat

#

And turn stereo off, but have the camera follow the head anyway

#

I recorded a few sequences of each of our trailers that way

if you are networking you can also record a replay and play it back later

Is there a built in system to do that?

@knotty rain you can enable the "Simple HMD" plugin to test your VR game

@knotty rain you should definitely have a VR headset to test a game with a VR mode

i have a friend with a vr headset but it takes a long time to compile then send then have him test and report if it even works at all

mighty carbon Nov 26, 2018, 4:35 PM

#

@sly elk I figured using external device for capturing would allow not dropping any frames

#

also, if you want to record in 4k, that would be misleading, since that's not what people will see in VR 😉

sly elk Nov 26, 2018, 4:37 PM

#

I think if I move to the nvidia branch and run their lens matched shading I will get better capture quality. That soft spot in the middle is really awkward

mighty carbon Nov 26, 2018, 4:37 PM

Hullooo everyone,

Asymmetrical VR gameplay is something people ask about on the forums, answers hub, and UDN occasionally. I got it working reasonably well, and I've made a sample project (initially for the purposes of getting help with it) and have made a little tutorial explaining what needs to be done and in some cases why.

Docs are here: https://calben.github.io/UnrealVrSpectatorControl/#/

It should work on mobile too, but some things not as well as I'd like (need to fix that sometimes words are cut off due to being verbatim blocks).

If you have time to give it a skim to see if anything might be unclear, I'd appreciate it! Github "stars" and "hey that's pretty good"s are also 100% welcome. :D

Thanks!

all of my stuff was private originally

that control plugin is a secondary engine window

#

which is where I was focused

vernal spear Nov 26, 2018, 7:58 PM

#

True. How would you keep the VR view rendering at full FPS with another window focused?

#

Or maybe it's not a problem since that other window would be a child process.

sturdy coral Nov 27, 2018, 1:12 AM

#

not sure on either plugin, but it should all be the same process

#

@sly elk you could manually set the lens mask to completely cover one eye pretty easy, then submit the other eye twice to the compositor to get a monoscopic view

#

that would be sort of hacky but probably less work than trying to make monoscopic be truely supported (there is some support for monoscopic far field for mobile)

#

that would give you some pixel shader headroom to increase things

Hey guys, any one know how I can match the orientation and origin position of Oculus/Vive/windowsMR/PSVR motion controllers? I developed on a Oculus CV1 and yesterday for the first time tested it on a VIVE set up. The orientation of my objects attached to the controllers were totally messed up. I was wondering if any one has any idea as to how each controller is oriented according to the motion controller component in UE4. This is my attempt at finding each ones orientation. But I only own a Oculus and none of the others so I cannot test.

someone knows where i can find animations for oculus touch controllers? for instance if i press a the button should go down based on input and play the animations

slim karma Nov 27, 2018, 2:31 PM

#

@cold siren @smoky comet have you guys taken a look at the build in controllers that come with the engine? I'm sure they can help you a bit with your issues

#

the oculus controller should be a decent basis to do the animations. the buttons even have vertex colors assigned that they use to highlight them. it should be easy to use that as a mask for a world position offset in the shader to simulate the animations

cold siren Nov 27, 2018, 2:36 PM

#

@smoky comet yes @slim karma is correct, the oculus mesh in the engine content has vertex colours that you can use

#

@slim karma i have the oculus with its origin sorted, you can see that in the image. the others are aligned to how i assume would be aligned, need some to either confirm or assist with location and orientation through their experience.. As i mentioned i only have an oculus set so unable to test on any other platform

slim karma Nov 27, 2018, 2:40 PM

#

well I only know Oculus and Vive, but in general it should be a good guess to imagine how you'd grip them and then move them accordingly to that position. I don't think you'll need to rotate them as the Vive is also just flat compared to the oculus controller

tired tree Nov 27, 2018, 2:46 PM

@slim karma not true, you hold the vive controller with a 30 degree or so pitch offset from the oculus one @cold siren I have a bunch of offset values that auto bring every controller type into alignment with the real world hand grip on them, but it likely wouldn't be very useful to you since its for a direct controller offset pathway I added. You kind of really need to actually get the controllers or add manual pitch adjustment and take input from testers.

#

some of the controllers really need more that rotation as well, WMR controllers have their base point way out in the ring and offset to the side from the grip

cold siren Nov 27, 2018, 3:06 PM

#

@tired tree Offsets is what I was looking for. Where can I find info on where the base point lies for each controller?

slim karma Nov 27, 2018, 4:14 PM

#

@tired tree that's weird, I've always had the vive controller exactly like it is in the engine and never had to rotate anything and it still felt right.

tired tree Nov 27, 2018, 4:15 PM

#

@slim karma if you are picking up relative then it will be, if you are positioning things like laser pointers or snap to hand objects then it will differ between controllers where it sits to your actual hand.

slim karma Nov 27, 2018, 4:41 PM

#

maybe we're talking about different things. I'm just saying that if you use the vive controller mesh like it is in unreal, it's already positioned correctly, but I realised that it has a very slight angle by default

tired tree Nov 27, 2018, 4:44 PM

#

not talking about meshes, the pivots for those and the procedural ones are already setup to match

#

talking about a uniform pickup / attachment angle regardless of controller type to the real life hand, IE: so gun angles feel normal

#

also things like mesh hands

sturdy coral Nov 27, 2018, 6:21 PM

#

@dusky moon several people have mentioned it in chat the last couple days, including the creator of it who is around

#

@smoky comet @slim karma @cold siren the oculus github branch has a template project with animated hands and controllers

#

@slim karma as a hack I have another component attached to oculus controllers that puts things into the same origin as oculus via steamvr:

#

 MotionControllerLSteamOrigin->SetRelativeTransform(FTransform(FRotator(40.0f, 0.0f, 0.0f), FVector(3.409f, -0.770f, 3.666f)));```

#

when running with the rift plugin I use that to get things back to steam, and when running with steam I just set MotionControllerRSteamOrigin to the motion controller itself instead of attaching another component

#

then just always use that instead of the motion controller when getting position

#

not the most efficient way, but it works and for multiplayer I'm doing something different

#

you still may want different gun angles and stuff though, but that at least gets you a base that is aligned between both plugins

sly elk Nov 27, 2018, 6:51 PM

@tired tree any rotation offsets you have would be useful. We do a check for steamvr vs oculus right now

I've noticed running Vive on a relatively large map that my FPS floats around 90fps or 40fps. Without VR the scene is 120+ fps.

I beleive it's related to draw calls as it depends how much is visible in the view. I'm just wondering why the frame rate is fixed to ~40 or ~90. Is the engine artificially controlling / limiting the fps?

sturdy coral Nov 28, 2018, 1:34 AM

@granite eagle pretty much if reprojection is active its either 90 or 45

you can turn off reprojection and get something inbetween

Another possibility for worse framerate is increased pixel count

sturdy coral Nov 28, 2018, 2:20 AM

#

more FOV in vr too makes for more draw calls

sturdy canyon Nov 28, 2018, 2:20 AM

#

You end up rendering like 2 1080p screens with of pixels on a Vive if you use sampling 1.0

#

More FoV, and two draw passes

sturdy coral Nov 28, 2018, 2:21 AM

#

1.0 pixel density now will choose whatever steamvr auto calculates for your graphics card

#

which is usually a little bit too high for ue4

sturdy canyon Nov 28, 2018, 2:22 AM

#

But instanced stereo helps reduce the doubled draw calls from two perspectives

sturdy coral Nov 28, 2018, 2:23 AM

on oculus I think it will still be 1x of ideal render resolution, which probably is about 2x 1080p

you can provide a custom hit result to the interaction widgets

@vernal spear I guess a part of the code in your new doc is not in the <Code> view therefore its a bit hard to copy

#

@dusky moon try refreshing the page and let me know if it's still an issue

tired tree Nov 28, 2018, 2:46 PM

Really the real solution would be to use instances of the classes, not spawn anything, and run the widget interactor logic purely manually in code

vernal spear Nov 28, 2018, 2:47 PM

#

@tired tree part of the reason i didn't do it that way in the first place is because when working on this part of the reason is for two VR players facing each other to be able to interact with spectator screens on opposite computers 😕

#

it was easier to let the control of the interaction switch between the networked computer and the player 0 VR widget interaction component

#

however, i'll definitely take another look at it and consider doing it as instances. if it were done that way, how would a programmer easily change the location of the widget in the 3d world?

tired tree Nov 28, 2018, 2:50 PM

#

you wouldn't need too

#

you can directly work with the widget

#

like the 3d widget and interactor already do

vernal spear Nov 28, 2018, 2:50 PM

#

ah, a method that doesn't have it in the world would be a nice option. most use cases wouldn't need it in the world anyway.

tired tree Nov 28, 2018, 2:51 PM

regardless this would all be moot if they would actually go in and finish the spectator window and add the ability to display a seperate viewport

@vernal spear fixed! and my last question is ... how can I possibly find the header for a Blueprint function library ? should I open the uasset in visual studio ?

vernal spear Nov 28, 2018, 2:52 PM

@tired tree wouldn't that be nice! maybe i'll pop in on the UDN and ask them if there's a timeline for that at the moment.

@dusky moon does your project have C++ code and a Visual Studio solution file?

vernal spear Nov 28, 2018, 2:53 PM

does your project have a blueprint function library associated with it?

dusky moon Nov 28, 2018, 2:53 PM

#

ah no ... I thought I should just make the Blueprint function library inside ue4 as an asset

vernal spear Nov 28, 2018, 2:54 PM

#

ah, go to File > New C++ Class

#

then in that dialogue select "Blueprint Function Library" as the base class, give it a name, and hit "create"

#

(i think. names of options may not be 100%)

#

actually, don't worry about it. it'll only take me 10 minutes to get the funtion library set up in its own module as a plugin

#

i prefer everything to be its own plugin normally, i just didn't do it for this bit of code because it was a bit rushed 😃

dusky moon Nov 28, 2018, 2:56 PM

#

Ah I see Thanks ... will do as you said

vernal spear Nov 28, 2018, 3:28 PM

alrighty @dusky moon the project is set up now so that there is a demo project and a plugin that can be added to your project as a git submodule. a git submodule add command has been added to the documentation. https://calben.github.io/UnrealVrSpectatorControl/#/?id=code-setup

i didn't specify a targeted engine version since it's a code only plugin. so it should work fine with 4.20.3 out of the box, but let me know if you run into an issue.

#

also it's entirely possible that the git submodules documentation could use a little more detail. so don't hesitate to say it isn't clear 😄

dusky moon Nov 28, 2018, 3:34 PM

#

haha I'm going to just download the repo from git and manually copy/paste the plugin

vernal spear Nov 28, 2018, 3:35 PM

#

yarp that'll do it!

dusky moon Nov 28, 2018, 4:17 PM

#

@vernal spear Man It works like a charm! Thanks a ton it's been a feature I've been craving for ages 💯 🔥

vernal spear Nov 28, 2018, 4:42 PM

#

Awesome!! Glad it worked!

granite jacinth Nov 28, 2018, 5:17 PM

#

Hm

#

Wasn't there someone selling a plugin like this a few days ago?

#

I'm actually surprised you haven't done something for it in your plugin @tired tree (or have you and I have been missing out!)

vernal spear Nov 28, 2018, 5:19 PM

#

The plugin on marketplace creates a child screen. I haven't purchased it to give it a look yet, though.

#

And I think it would make sense to add this to @tired tree 's plugin for an instanced version. I'll look into it and make a pull request when I have time

#

(assuming you accept PRs into it @tired tree )

granite jacinth Nov 28, 2018, 5:26 PM

#

@vernal spear You going to adjust your code with Mort's suggestion about custom hit result widget interactorst?

#

Man. Rendertargets can get pretty expensive

vernal spear Nov 28, 2018, 5:28 PM

#

@granite jacinth yup, it's going on the to-do list. I think it makes sense both for an in world and an instanced solution.

granite jacinth Nov 28, 2018, 5:29 PM

#

Especially if you're on a real budget

vernal spear Nov 28, 2018, 5:29 PM

#

Yeah that's the real killer, and there doesn't seem to be a way around it!

#

Another problem is if you pipe the render target texture directly to the VR spectator there are gamma issues, which I still need to sort out without incurring a performance cost if possible.

granite jacinth Nov 28, 2018, 5:32 PM

#

Hm, technically... if you didn't care about spectator, you could use this to say spawn items in the level right?

#

I mean, since you're just interacting with a widget

vernal spear Nov 28, 2018, 5:33 PM

#

Yarp. We use it for a few things where a user needs to be able to control the VR experience

granite jacinth Nov 28, 2018, 5:34 PM

#

Hm, and is it just one widget per spectator screen basically?

vernal spear Nov 28, 2018, 5:35 PM

#

Yes, there needs to be a master widget to compose multiple widgets

#

I'm not sure how messy that gets in Blueprints. I still do almost all my UI logic in C++, and even then with a lot of composed widgets it gets a little messy.

granite jacinth Nov 28, 2018, 5:37 PM

#

It's not bad during it in UMG

vernal spear Nov 28, 2018, 5:39 PM

#

I've been doing it using UUserWidgets and meta=(BindWidget). So it's kind of IMG, but for one of my apps there are a lot of submenus and selectors. I very nearly switched to making a WebView :D

tired tree Nov 28, 2018, 5:39 PM

#

@granite jacinth to be honest it isn't currently what I would consider clean enough to add

#

I was pushing for epic to actually fix the issue instead

#

you can emulate the same thing entirely in BP, that is what fantisfall was doing

vernal spear Nov 28, 2018, 5:39 PM

#

That's true, better for them to finish the spectator viewport mode

tired tree Nov 28, 2018, 5:39 PM

#

people have been using pretty much the same thing since spec screen came out

#

bit wary of "fixing" things with hacks that should be fully fixed in engine...look how long advanced sessions has kept multiplayer BP

#

s limping along without any epic fixes

granite jacinth Nov 28, 2018, 5:40 PM

#

@tired tree you should just stop

#

kill it

#

then they'll get off their asses

tired tree Nov 28, 2018, 5:40 PM

#

no they won't

granite jacinth Nov 28, 2018, 5:41 PM

#

well, at least the pitchforks will come out

vernal spear Nov 28, 2018, 5:41 PM

#

Not needed for Fortnite 🤑

tired tree Nov 28, 2018, 5:41 PM

#

its been 3 years, supporting it at least helps the people with no alternatives

#

I put up a big old warning about the state of sessions on the OP of it at least

#

and feature locked it except for bug fixes

How can I export an exe file of a small scene I created to view it in VR ?

#

I have a Samsung headset

frigid kite Nov 29, 2018, 9:51 AM

#

You'll have to build it as a Gear VR .apk, you can't just straight up run a Windows .exe on an Android phone

hazy aspen Nov 29, 2018, 9:53 AM

#

I dont want to run it on android

#

I want to run it on windows only

frigid kite Nov 29, 2018, 9:56 AM

#

Ooh, the odeyssey, my bad

#

So what kind of .exe are we talking here? Did you build something in Unreal?

hazy aspen Nov 29, 2018, 9:58 AM

#

I have a simple scene here with some basic light animations and I want an exe so that I don't have to open ue4 to view it.

frigid kite Nov 29, 2018, 10:01 AM

#

Alright, first go into Settings > Proejct settings

#

search for "vr" at the top, enable Start in VR so the exe will start in vr by default

#

(otherwise you have to add "-vr" as a command line argument)

#

Then file > package project > windows > windows 64 bit

hazy aspen Nov 29, 2018, 10:03 AM

#

also I unintentionally configured the project for android, will it have any effect now, how can I unconfigure if it will ?

frigid kite Nov 29, 2018, 10:05 AM

#

Hmm, I'm not sure what unreal changes when you configure for android

#

But it should still work just fine on desktop

hazy aspen Nov 29, 2018, 10:06 AM

#

I get this when I try to export for Desktop

📎 unknown.png

#

I never got this when I exported earlier

frigid kite Nov 29, 2018, 10:08 AM

#

Maybe it added some c++ code that needs to be compiled after configuring for android

#

You can just go ahead and install visual studio, you'll likely need it sooner or later anyhow

hazy aspen Nov 29, 2018, 10:08 AM

#

yup, ill do that. Thanks

hazy aspen Nov 29, 2018, 11:24 AM

#

@frigid kite Hey installed VS 2017 and tried exporting the project and it gave me "common tools for visual c++" not installed.. I then reinstalled with common tools but version 2015 and It asks for 2017 which doesn't have/cant find common tools apparently

frigid kite Nov 29, 2018, 11:25 AM

#

You need to run visual studio installer

#

then click modify on your VS 2017 Community

#

and at the top you'll need to check C++ development

#

there's also C++ game development further down which explicitly mentions Unreal, but I don't have that installed myself and it works just fine

hazy aspen Nov 29, 2018, 11:26 AM

#

you mean "Desktop devlopment with c++" ?

frigid kite Nov 29, 2018, 11:26 AM

#

yes

#

You could also try the game development with C++, I reckon that should also work

hazy aspen Nov 29, 2018, 11:26 AM

#

okay

tropic oracle Nov 29, 2018, 12:01 PM

Hi, My Oculus Desktop App is automatically launched when I hit the Play-button in Unreal Editor.. though I am using the First Person Template.

#

Can I deactivate the auto launch ?

mighty carbon Nov 29, 2018, 12:36 PM

No, you can't

Hey I was trying to get some stereo captures using the Stereo Panoramic plugin but when I input the command I do not get any results.

frigid kite Nov 29, 2018, 1:07 PM

#

Then you're not doing something correctly

sturdy coral Nov 29, 2018, 2:53 PM

#

@tropic oracle you can remove the oculus plugin from your project

#

if it is happening due to steamvr you can remove it too or add this patch and it may help:

https://github.com/EpicGames/UnrealEngine/pull/4950

#

if VR is disabled in your project that steamvr one shouldn't happen, it is only when bStartInVR is true and you launch with -nohmd

tropic oracle Nov 29, 2018, 3:02 PM

#

@sturdy coral Thank you. Disabling the plugin helped.

sturdy coral Nov 29, 2018, 3:51 PM

#

hmm, just noticed Control Rig was added as an experimental plugin, seems to have been there a while

#

mighty carbon Nov 29, 2018, 3:52 PM

btw, if you disable Oculus plugin, you don't get access to any of Oculus BP nodes.

#

(at least that's what happened to me once, a few releases back)

sturdy coral Nov 29, 2018, 3:53 PM

#

not very intuitive to get started with it:

#

#

seems you make your own ControlRig subclass first, but crashed when I tried

#

ah, here we go:

#

https://docs.unrealengine.com/en-US/Engine/Animation/ControlRig

#

I'll see if it is usable for any VR IK stuff, it is supposed to have real constraints and stuff

tired tree Nov 29, 2018, 4:02 PM

#

it looks amazing tbh

sturdy coral Nov 29, 2018, 4:03 PM

#

to create a class, do it through content browser - > create advancecd assset -> animation -> control rig

#

what was failing for me was trying to do it by create blueprint class, and selecting control rig as parent
