and have like 8 of their phones too

#

guess ive just been getting lucky or summin ^^

full junco Oct 5, 2017, 2:21 PM

#

yeah

trail shale Oct 5, 2017, 2:29 PM

#

Do I still need a player controller or a motion controll? I've been able to get Vr to work in the project by changing the default pawn to the VR Pawn, and it tracks and has a hand, but none of the movement controls work

real needle Oct 5, 2017, 2:31 PM

#

ye you need to add a motion controller to the player

#

or well, 2

trail shale Oct 5, 2017, 2:31 PM

#

so it default isn't added to the VR pawn? the camera is

real needle Oct 5, 2017, 2:32 PM

#

correct

#

you may wanna look at the first person template, or the virtual reality template

#

they both show you bscly all aspects of vr

trail shale Oct 5, 2017, 2:32 PM

#

I am but I'm not sure what comes over when I migrated

real needle Oct 5, 2017, 2:32 PM

#

ah

trail shale Oct 5, 2017, 2:33 PM

#

so I'm clicking on the pawn in the example

real needle Oct 5, 2017, 2:34 PM

#

and? 😛

tired tree Oct 5, 2017, 2:35 PM

#

the camera by default locks to HMD position in engine

#

so it will always work

trail shale Oct 5, 2017, 2:35 PM

#

Yeah the HMD is working fine

tired tree Oct 5, 2017, 2:35 PM

#

Epic spawns the motion controllers as seperate objects

trail shale Oct 5, 2017, 2:35 PM

#

and I have a hand (although the performance is terrible on the hand, but everywhere else in the level is great)

tired tree Oct 5, 2017, 2:35 PM

#

because they have all of those attached teleportation components with them and I guess they wanted to support no controller setups?

real needle Oct 5, 2017, 2:36 PM

#

ye

tired tree Oct 5, 2017, 2:36 PM

#

what is the motion controller attached to

real needle Oct 5, 2017, 2:36 PM

#

afaik too the pawn

tired tree Oct 5, 2017, 2:36 PM

#

talking about his

real needle Oct 5, 2017, 2:36 PM

#

opening ue4 myself to check now

tired tree Oct 5, 2017, 2:36 PM

#

no epics, I am aware of how epic oes it

real needle Oct 5, 2017, 2:36 PM

#

ah

tired tree Oct 5, 2017, 2:37 PM

#

I keep my controllers as part of my base character, if something doesn't have controllers it is easy enough to deactivate them or destroy them

trail shale Oct 5, 2017, 2:37 PM

#

That's just it, I can't see even in the example, WHERE the controllers are

#

it works fine when I run it

tired tree Oct 5, 2017, 2:37 PM

#

they are spawned

#

on begin play

trail shale Oct 5, 2017, 2:37 PM

#

but if I wanted to change the mesh, I wouldn't know how

#

BP_TeleportControllers

#

seperate actors

trail shale Oct 5, 2017, 2:39 PM

#

so, to make my project VR ready, (I have already migrated all assets) I need to add a Motion Controller Vr Pawn (settting it as default in the game mode) .... annnnnnd???

real needle Oct 5, 2017, 2:39 PM

#

depends on your project & how far along you are

#

for example weapons/items u hold

tired tree Oct 5, 2017, 2:40 PM

#

should work from there, you'll want to make sure it is actually spawning the controllers

trail shale Oct 5, 2017, 2:40 PM

#

I am just using a simple pawn

#

oh it's an input problem

#

event references are unknown because I never made the input keys? I thought that was native or whatever

#

Or maybe it's outdated?

real needle Oct 5, 2017, 2:41 PM

#

could be outdated

tired tree Oct 5, 2017, 2:41 PM

#

did you copy the config over?

#

it has the input bindings

real needle Oct 5, 2017, 2:41 PM

#

orite, if u moved your project over into a new one you need to copy that too

tired tree Oct 5, 2017, 2:42 PM

#

defaultinput.ini

trail shale Oct 5, 2017, 2:42 PM

#

no I did not copy the config over, that must be it

#

I don't want to overwrite any binds, where is the ini files for both located and I will just copy and paste the bits I need

tired tree Oct 5, 2017, 2:43 PM

#

yup

#

config file

#

in the project

#

defaultinput.ini

trail shale Oct 5, 2017, 2:47 PM

#

Maybe that's why the hand was so jittery, it was throwing errors every single time an Update occured

#

Hm... still not working

tired tree Oct 5, 2017, 2:54 PM

#

is it just jittery?

#

if so you might be falling below frame rate

#

since your scene is 2d normally

trail shale Oct 5, 2017, 2:55 PM

#

no, it's 3D and I'm running a 1080 TI with 7700k

#

Also, everything BUT the hand works super smooth, so I must not have hooked everything up

#

the inputs are there and the errors on the motion controller are gone

#

but i'm not getting all the same effects

tired tree Oct 5, 2017, 2:56 PM

#

i meant 2d screen

#

have you actually turned on the stat graph?

trail shale Oct 5, 2017, 2:57 PM

#

nope, I should

tired tree Oct 5, 2017, 2:57 PM

#

because the hands are where you will notice the frame drop

trail shale Oct 5, 2017, 2:57 PM

#

ugh, I'm stuck in Vr mode, escape doesn't work neither does alt+V

#

that was weird

#

how do I turn on stat graph again ?

tired tree Oct 5, 2017, 3:01 PM

#

stat unit is prob what you want

trail shale Oct 5, 2017, 3:03 PM

#

what do the numbers mean? they say m/s, not FPS

#

so it says like 30 m/s for Frame

#

that's at engine scalability from low to epic, no change, so I know this isn't performance based

tired tree Oct 5, 2017, 3:05 PM

#

you need 11ms

#

in VR

#

to hit 90FPS

#

1000 ms is a second, 1000 / 90 = 11.11 ms

#

you WANT to hit 90fps in vr

trail shale Oct 5, 2017, 3:06 PM

#

yeah, I'm hitting like 20 ms

#

And it is on a BIG, unoptimized Map

#

22 ms? that would be 45 fps, would mean it is reprojecting if using steamVR

#

and would explain why the controllers are blurred / jerky

trail shale Oct 5, 2017, 3:07 PM

#

it seems smooth except for the hands

tired tree Oct 5, 2017, 3:07 PM

#

they are being tracked at half speed

#

its not smooth, it is doubling frames for you

#

so you don't get sick

trail shale Oct 5, 2017, 3:08 PM

#

so what does it mean?

#

What do I need to do?

noble charm Oct 5, 2017, 3:08 PM

#

Optimize and hit 11 ms

trail shale Oct 5, 2017, 3:08 PM

#

the controls aren't working though, I didn't migrate something or set it up

#

Here is exactly what I did...my project before had ZERO VR in it

#

So I migrated all folders from a New VR BP Project with all the content

#

then I added MotionControllerPawn to map, and changed the default pawn to that

#

then I imported the inputs from the VR template

#

that's it...

#

But it doesn't teleport around like the VR template

noble charm Oct 5, 2017, 3:11 PM

#

You must be missing some things then

trail shale Oct 5, 2017, 3:11 PM

#

That's what I'm asking for

#

Do I need to do anything to BP_MotionController or is it already hooked into the Motion Controller Pawn?

tired tree Oct 5, 2017, 3:16 PM

#

its already there or you wouldn't see the controller

trail shale Oct 5, 2017, 3:16 PM

#

And I don't need to change the PlayerControllerClass in the game mode correct?

tired tree Oct 5, 2017, 3:17 PM

#

I don't remember if they have a custom player controller or not, I haven't use their template for anything, but you shouldn't

trail shale Oct 5, 2017, 3:19 PM

#

I will build it from scratch just to learn but I wanted to try it out because it's been a 5 month wait to be able to try this in VR... also I wanted to see what else needs to be done, from the looks of it, this gigantic map is going to have to have some serious optimizing

#

Yes, a blue rod comes out

#

That's it, when I try to teleport

#

Do I need to do anything with Navmesh bounds?

#

that was it... I needed NavMesh bounds

#

Are there any guidelines for NavMeshes for VR? Or is simply define where the player can teleport (and it must intersect with floor

tired tree Oct 5, 2017, 3:35 PM

#

navmeshes in their setup are used just for checking valid teleport locations

#

You can use them for actual navigation of the player as well of course

trail shale Oct 5, 2017, 3:42 PM

#

Ah okay, thanks, I've almost got it working

#

Holy shit this is wild

#

Here's a question - Before I was teleporting my player around using the controller as a reference before transforming it via a new vector and a seperate new rotation.....do I just need to change the controller reference to motion controller?

#

the teleport function WORKS but I need to adjust the position

#

https://www.dropbox.com/s/n5n53setwq8nnjq/Screenshot 2017-10-05 12.05.33.png?dl=0 do I need to change playerpawn or controller?

#

Can someone point me to the best optimization tips for Unreal & Vive (I've read the best practices one) but now I need to optimize this map big time

Hey folks! Quick question on player boundaries (Vive). I'm teleporting the user to new locations, and I need to force-set not only the MotionControllerPawn, but the users location itself as well (aka the camera) to prevent teleporting inside of geometry. Does anyone know, inside the blueprint, exactly which actor I need to teleport?

#

Is it GetPlayerCameraManager?

#

or a child of GetPlayerPawn? <-- if I understand, this is like casting To MotionControllerPawn, correct? I've tried setting transforms of the Camera from this Cast but no dice =l

glossy agate Oct 6, 2017, 3:08 AM

#

Well the nav mesh should stop that right? You can use blocking volume on the mesh.

#

Are you the real velveeta company? What kind of weird cheesy shit are you trying to do in VR?

ashen nexus Oct 6, 2017, 3:51 AM

#

lol naw just my name I swear :p

#

and we're not using NavMeshes in this, the floor is a custom per-poly collision mesh, also this teleporting is not referring to the controller teleport but a separate warp feature to warp to key locations

ashen nexus Oct 6, 2017, 6:54 AM

#

Ok so apparenty I can't force set the camera's location...

#

tried both SetWorldLocation and SetRelativeLocation on MotionControllerPawn's Camera component, and neither of them change the camera's position

#

I can if I disable LockToHMD on the camera component..

ashen nexus Oct 6, 2017, 8:50 AM

#

well i figured it out 😛 inside MotionControllerPawn, I'm moving the SceneRootComponent such that the user's head ends up where I want it

#

and now i realize that that's the only way to do it, as moving the head itself would totally mess up the user's boundaries lol...

@dusk vigil nice little review, ty for the share

@full junco you should read it too, considering our discussion yesterday, turns out its really not as bad a picture as u painted it to be 😄 (which im sure you'd like to know too, as in, theres still hope for wmr lol)

tired tree Oct 6, 2017, 12:15 PM

#

Not really, appears to be just about as expected?

#

He is working around its downsides to get it functional, John was arguing for near perfect tracking not being possible. For many uses (especially business) the MR headsets are likely great as is and without workarounds.

alpine torrent Oct 6, 2017, 12:17 PM

#

you can make it 200% accurate tracking

tired tree Oct 6, 2017, 12:17 PM

#

@real needle ok

real needle Oct 6, 2017, 12:44 PM

#

so yea, hands behind back is definatlly an issue, but good to read its not as big an issue as we concluded yesterday, because appearantlly the gyro tracking is surprizingly good

#

just thought youd like that little info too ^^

full junco Oct 6, 2017, 12:46 PM

#

well I actually saw that post on reddit and stopped reading after the first half because, well, what he says is just obvious and nothing new

#

accelerometer data from the controllers and headset is simply fantastic. You can look at the controller shadow behind you and rotating your hand around is spot on. More impressively, you can cover the cameras on the headset, and while it does lock your position, the rotational data is perfectly accurate at 90fps and I can’t tell the difference.

#

that just shows that he has no clue how the stuff actually works

#

rotation is always perfect, you dont need any cameras for that

#

your phone can also perfectly tell you the rotation it has

#

and every quadcopter needs perfect >200 hz gyro too, so thats absolutely nothing special, but he makes it sound like microsoft would have achieved anything impressive here

real needle Oct 6, 2017, 12:51 PM

#

Yes and no, you definatlly have a point, but i think your overestimating the quality of sensors in phones and quadcopters, they tend to go for cheap ones (ie; chips for smartphones) and then just do some proper guestimating with software

#

wich obviously can be the case for M$ too

#

idk, proper reviews will tell

#

it shouldnt get confused when walking around near magnetic fields, unlike phones

full junco Oct 6, 2017, 12:52 PM

#

"overestimating the quality of sensors in phones and quadcopters"? in quadcopers good gyro data is way more important than in VR headsets

#

and phone gyros will also not be confused by magnetic fields

#

gyros are perfect for many years now

real needle Oct 6, 2017, 12:55 PM

#

i pmuch disagree 😛

#

i hobby in robotics alot

#

a 5 bucks gyro will fly a quadcopter and balance a robot

#

but a 150 bucks one will give u so much more detailed info about translation

#

i guess im sorta confusing two things tbh

#

gyros and imu's

#

imu's are packages of gyro & accelorometer

#

same story tho, they come for cheap and for premium prices

#

and really, the cheap ones are just that, cheap

full junco Oct 6, 2017, 12:57 PM

#

the guy on reddit said the "accelerometer data" would be fantastic, while he just talked about the gyro

real needle Oct 6, 2017, 12:57 PM

#

hmm lol didnt notice that

full junco Oct 6, 2017, 12:57 PM

#

he has no clue how the stuff works

#

what more detailed info about "translation" will a $150 IMU give you compared to a $30 one?

real needle Oct 6, 2017, 12:58 PM

#

alot less noise for one

#

meaning alot less guestimating needed via software

#

and u can usually poll em faster, but ive never really needed that

full junco Oct 6, 2017, 12:59 PM

#

translation isn't tracked at all by the IMU for the windows controllers, translation is 100% dependent on the camera

real needle Oct 6, 2017, 1:00 PM

#

its mostly just that what you get is actually whats its sensing

#

yea tru

#

dang lol

#

well fine

#

i will try get you stoked about wmr again in the future, consider yourself warned 😛

full junco Oct 6, 2017, 1:01 PM

even cheap IMUs are 1000 hz

#

and yeah, feel free to try to exite me about windows mr again 😄

real needle Oct 6, 2017, 1:01 PM

#

xP

#

pricey imu's hover around 10000hz btw ^^

full junco Oct 6, 2017, 1:03 PM

#

well you absolutely don't need those for rotational tracking of a controller in VR

#

there even 200 hz is pretty much perfect, the speed you can turn your hand with is very low

real needle Oct 6, 2017, 1:04 PM

#

problem is your hand is attached to a bunch more joints/your whole body

#

so add movement of other joints and u can turn your hand quicker 😛

well yeah, thats true

#

by far the most people that buy it are gamers

tired tree Oct 6, 2017, 1:26 PM

the headsets are straight designed to bring VR into the boardroom

#

thats their gamble, that microsoft can tie into its office partners and sell VR as a corporate asset

full junco Oct 6, 2017, 1:29 PM

#

currently VR is almost just about gaming market though

#

when windows MR won't just be VR any more then stuff might be different, but currently its just VR

tired tree Oct 6, 2017, 1:30 PM

#

?

#

have you SEEN the architecture interest in VR? or the medical? or the engineering?

#

its massive

full junco Oct 6, 2017, 1:30 PM

#

"interest"

#

its not where HTC or oculus makes their money with though

tired tree Oct 6, 2017, 1:30 PM

#

of course not, their systems are unweildy for that purpose

#

thus microsofts MR

#

they are trying to corner that market

#

there are a lot of people already working on applications for those.....MR is their perfect platform

full junco Oct 6, 2017, 1:32 PM

#

it is better, due to no setup required, but the amount of applications that can only work without having to setup some area for it isn't that big I think

#

most of that architecture or medical or whatever stuff you can do on vive or rift just same like on windows MR

tired tree Oct 6, 2017, 1:33 PM

#

not on the road

#

at a client

#

not as easily as sitting down at a table with a laptop

full junco Oct 6, 2017, 1:33 PM

#

for many applications the client can come to you

tired tree Oct 6, 2017, 1:33 PM

#

even then

#

any office can be used without cameras and setup

#

I don't know why you are so down on it, its applications are obvious

#

and there is interest

full junco Oct 6, 2017, 1:34 PM

#

when the client comes to you, then you have a room for that anyways, and then it also doesnt hurt you to have cameras or lighthouses installed there

tired tree Oct 6, 2017, 1:34 PM

#

I'll agree its kind of terrible for good gaming

#

but that is its side market imo

full junco Oct 6, 2017, 1:35 PM

#

well I don't think its terrible for gaming

I think the main market for windows MR will be xbox, because thats what its absolutely perfect for

mighty carbon Oct 6, 2017, 1:35 PM

#

so, how do I get a free MR HMD from Samsung ? 😃

full junco Oct 6, 2017, 1:36 PM

#

its way better than PSVR regarding the tracking, and PSVR is already very successfull

mighty carbon Oct 6, 2017, 1:36 PM

#

@alpine torrent any insight on how to get a free Samsung MR HMD? 😃

alpine torrent Oct 6, 2017, 1:36 PM

@mighty carbon If I know I would tell you

mighty carbon Oct 6, 2017, 1:37 PM

😦

full junco Oct 6, 2017, 1:37 PM

#

and with xbox scorpio MS has the perfect console for VR

tired tree Oct 6, 2017, 1:38 PM

#

it is def better for console than psvr

#

its also a little over engineered for that

full junco Oct 6, 2017, 1:38 PM

#

how?

tired tree Oct 6, 2017, 1:39 PM

#

they could have dropped the price and lowered the quality if they wanted to target just consoles

#

but its multiuse

#

thats fine

full junco Oct 6, 2017, 1:40 PM

#

it is multiuse, but xbox is the perfect market for it where most of the headsets will be sold for

#

in 5 years maybe the professional applications will be more important than games, but in the next few years, gaming will absolutely dominate the VR market

alpine torrent Oct 6, 2017, 1:41 PM

#

I bet it going there

tired tree Oct 6, 2017, 1:41 PM

#

have you spoken with anyone from say China about the VR interest there John?

full junco Oct 6, 2017, 1:41 PM

#

no

tired tree Oct 6, 2017, 1:42 PM

#

I have been messaged by 12 dev teams out of there

#

all working on industrial applications for VR

full junco Oct 6, 2017, 1:42 PM

#

well its probably easy to get investor money for that currently

tired tree Oct 6, 2017, 1:42 PM

#

not to mention outside of china, us interest and eu

full junco Oct 6, 2017, 1:43 PM

#

and what did you tell the 12 dev teams?

tired tree Oct 6, 2017, 1:43 PM

#

I sent them contact information for some people and sent them on their way....a few I sent to Unity

#

as much as that hurt to do

full junco Oct 6, 2017, 1:44 PM

#

didn't they want to pay you to do stuff?

tired tree Oct 6, 2017, 1:44 PM

#

yes

full junco Oct 6, 2017, 1:45 PM

#

do you not want to work on any industrial applications because its boring, or are you just too busy with other stuff?

tired tree Oct 6, 2017, 1:46 PM

#

I have 2 (soon 3) kids, a full time job, and a life, VR is my hobby not my business

#

no real interest in working remotely through a language barrier

full junco Oct 6, 2017, 1:46 PM

#

ah, well, makes sense then

tired tree Oct 6, 2017, 1:47 PM

#

I like the application concepts actually

#

one was an MRI scanner program where you could slice and interact with the 3D point cloud

full junco Oct 6, 2017, 1:47 PM

#

kind of like that one thing in the lab?

tired tree Oct 6, 2017, 1:48 PM

#

yeah except actual point data, much more detailed, zoom and different view modes ect

full junco Oct 6, 2017, 1:48 PM

#

I agree that such stuff is interesting, but it will be a long time until millions of headsets are sold for these usecases

alpine torrent Oct 6, 2017, 1:50 PM

#

@tired tree so you could use data in a database and AI where the data is so it could help

tired tree Oct 6, 2017, 1:51 PM

#

you mean stored positions and machine learning? that doesn't fix total tracking loss, it helps with drift to a point

#

eventually data starvation can't be accounted for

alpine torrent Oct 6, 2017, 1:55 PM

#

yeah machine learning where you store the data from MRI

tired tree Oct 6, 2017, 1:58 PM

#

oh you are talking about the MRI program

real needle Oct 6, 2017, 1:59 PM

#

does anyone here have some experience with the stereoscopic 360 rendering in UE?

#

the kite and lighting plugin?

alpine torrent Oct 6, 2017, 2:00 PM

#

@tired tree well the concept like that AI where deeplearning and machine learning do the work where data is stored so then application itself can do stuff like slicing

tired tree Oct 6, 2017, 2:01 PM

#

thats fairly unnecessary...

spiral zephyr Oct 6, 2017, 2:33 PM

#

arcore handles short term complete tracking loss, but no idea how many "memories" are stored before old ones are destroyed. Havent pushed any limits yet, but its been impressive for indoor use. Plain old cut wood is close to the ideal surface to track, but posters on the wall do the job too.

#

been using the arcore template project on googles 4.17.1 engine source.

#

short term as in 10 seconds of wildly moving/escaping room/phone in pocket..then return to room and BOP everything where it should be. let me know if i should try something else.

Knew the improvments where coming in future updates! This is why I like UE4.💯

wicked oak Oct 6, 2017, 3:41 PM

#

@glad plank since allways, epic only develops the features THEY need

#

can backfire for people that do things that epic isnt interested in

#

you only need to see people complaining about multiplayer performance since the UDK days, and now epic adding mayor upgrades to the server

tired tree Oct 6, 2017, 3:45 PM

#

that just means it is time to convince Palmer to hire Epic to make an open world fully dynamic lighted GI VR game

#

oh with playable 2D game on tablets so paper gets upgrades too

wicked oak Oct 6, 2017, 3:48 PM

#

lol

#

pretty much

#

look at oculus bankrolling Epic for VR

#

thats the only reason the forward renderer exists

#

but seems they have now stopped continuing it as robo recall is done 😦

#

thats sad becouse that forward renderer could have better performance than the deferred renderer

#

and more customizable shaders

tired tree Oct 6, 2017, 3:49 PM

#

it already does though

#

just gets canceled out with MSAA

#

granted some of that is due to missing features..

wicked oak Oct 6, 2017, 3:52 PM

#

but msaa gives great image

#

with a bit of tweaking, the unreal forward renderer could be like the Doom one

#

essentially also rendering to a gbuffer for postprocess, but a thinner one

tired tree Oct 6, 2017, 3:53 PM

#

didn't they add gbuffer features in a limited sense already do it?

wicked oak Oct 6, 2017, 3:53 PM

#

i think not

tired tree Oct 6, 2017, 3:53 PM

#

they use it for specific things

#

oh

#

nvm

#

I was thinking reverse

#

they do forward rendering with specific features with the deferred now

wicked oak Oct 6, 2017, 3:54 PM

#

for transparency

#

that way they get full quality transparency without random hacks

tired tree Oct 6, 2017, 3:57 PM

#

yeah

#

when you get right down to it, fully deferred was top of the line when UE4 was started

#

but clustered forward kind of killed that title

#

the new forward renderer is a higher potential path

#

but they would really have to commit to it

wicked oak Oct 6, 2017, 4:01 PM

#

another thing with that forward renderer is that it scales quite well

#

you can turn the gbuffer completely and make it a "pure" deferred "easily"

#

for higher speed

#

mobile gpus dont like deferred

#

the mobile renderer is forward

#

and in fact, they have ported the desktop forward renderer to IOS

tired tree Oct 6, 2017, 4:03 PM

#

oh did they? its not on the simple forward anymore? or is it optional?

#

didn't see that

wicked oak Oct 6, 2017, 4:04 PM

#

its on 4.18 preview

#

clustered forward works SPECIALLY well on mobile gpus

#

they are tiled after all

#

so if you make your clustered forward use the same tile size, your memory access and branching is homogenous

#

and they mention metal. In vulkan you can call command buffers per tile

#

so you could actually just send the light data there

#

per tile

#

instead of saving it in a texture

mighty carbon Oct 6, 2017, 4:38 PM

#

so, forward renderer is now poop in UE4 ?

#

like, should I use deferred for VR nowadays ?

sturdy coral Oct 6, 2017, 4:40 PM

#

I've seen some research somewhere about having a small gbuffer per tile and doing all the passes there

#

So low memory overhead

#

Some stuff doesn't seem like it would work with that alone though, like ssao

#

@mighty carbon I would say it depends on your content

mighty carbon Oct 6, 2017, 4:42 PM

#

?

#

@sturdy coral what do you mean ?

sturdy coral Oct 6, 2017, 4:44 PM

#

Some stuff is better suited to deferred still, though most of that stuff could work fine with forward + taa too

#

Not just content but final look

#

Forward doesn't support everything

tired tree Oct 6, 2017, 4:45 PM

#

generally forward is best for VR

#

its not "poop"

#

and its better than before...not worse

mighty carbon Oct 6, 2017, 4:45 PM

#

so when should I use deferred ? What would be the practical use case ?

sturdy coral Oct 6, 2017, 4:46 PM

#

Yeah nothing has regressed, they were just saying you can use desktop forward in addition to simple forward on mobile now

#

At least on ios

#

Ssao, light functions

glad plank Oct 6, 2017, 4:47 PM

#

I prefer deffered for lighting but we need better GPUs to brute force it.

sturdy coral Oct 6, 2017, 4:47 PM

#

Certain shadows aren't supported

glad plank Oct 6, 2017, 4:47 PM

#

my 980ti doesn't like deferred VR. We might be using it in our game for shadow reasons

mighty carbon Oct 6, 2017, 4:47 PM

#

light functions don't work with forward? bizarre :/

sturdy coral Oct 6, 2017, 4:47 PM

#

They kind of work but not fully everywhere

#

Baked landscape with near cadcades

glad plank Oct 6, 2017, 4:48 PM

#

But our game wont be out ulta way after new gen cards make VR Deferred much more viable

sturdy coral Oct 6, 2017, 4:48 PM

#

Cloud shadows will only show up in the near cadcades and not the distance

#

But they work with deferred

glad plank Oct 6, 2017, 4:49 PM

#

The light limitations for forward are kind of unfortunate

mighty carbon Oct 6, 2017, 4:49 PM

#

I was thinking about using light function to fake clouds casting shadows on my landscape @sturdy coral

glad plank Oct 6, 2017, 4:49 PM

#

I mean, there is a reason almost all modern games us deferred right?

sturdy coral Oct 6, 2017, 4:50 PM

#

Try every feature you are going to want to use early

#

Don't make all your content optimized for forward and only then test if other stuff you want will work

#

But they are improving it pretty often

mighty carbon Oct 6, 2017, 4:50 PM

#

also could use post processing ink outlines (they don't work with forward), since they look x1000 better than the one I use now

tired tree Oct 6, 2017, 4:54 PM

#

they DO work with forward

#

I told you that they don't work with MSAA

#

and that the issue is only when you are doing partial occlusion

mighty carbon Oct 6, 2017, 4:56 PM

#

I contacted author of https://www.unrealengine.com/marketplace/post-process-shader-pack-vol and he said the stuff works only with deferred

did he try it without MSAA?

#

he is using custom depth

mighty carbon Oct 6, 2017, 4:57 PM

#

That I don't know

#

why would I want to use forward without MSAA ?

tired tree Oct 6, 2017, 5:00 PM

#

faster

mighty carbon Oct 6, 2017, 5:01 PM

#

yeah, but AA is a must in VR

tired tree Oct 6, 2017, 5:01 PM

#

you can run FXAA with forward

mighty carbon Oct 6, 2017, 5:01 PM

#

(Oculus won't let a game in the store without AA)

tired tree Oct 6, 2017, 5:01 PM

#

but yeah, MSAA is obviously the best choice

mighty carbon Oct 6, 2017, 5:19 PM

#

so what's the downside of using deferred in VR ?

sturdy coral Oct 6, 2017, 5:22 PM

#

TAA blur, performance, and gbuffer memory usage

mighty carbon Oct 6, 2017, 5:22 PM

#

oh, performance.. that sucks :/

sturdy coral Oct 6, 2017, 5:22 PM

#

performance depends on what you are doing

glossy agate Oct 6, 2017, 5:24 PM

#

Isn't forward like 20% savings or something? Or I guess dependent on the features used. Im just going with deferred.

sturdy coral Oct 6, 2017, 5:25 PM

#

performance difference depends a lot on your geometry too if you are using mssa

glossy agate Oct 6, 2017, 5:28 PM

#

Yeah my foliage pack didn't work in forward so I went back. Made the palm trees all transparent even the trunks of trees.

sturdy coral Oct 6, 2017, 5:29 PM

#

ah weird

#

one of the robo recall mod maps from unreal tournament has some foliage and that works ok

tired tree Oct 6, 2017, 5:29 PM

#

they were probably using dithered transparency

#

you can unlink that in the material

mighty carbon Oct 6, 2017, 5:30 PM

#

ok, so let me put questions this way - if you are doing vast open landscape with some indoor stuff over it and under it, day/night cycle and everything has anime'ish ink outline, what renderer should I use ?

tired tree Oct 6, 2017, 5:30 PM

#

either and not be VR?

#

you are going to be in for one hell of a time optimizing that for vr

sturdy coral Oct 6, 2017, 5:30 PM

#

you can wait on vulkan and even then g/l

mighty carbon Oct 6, 2017, 5:31 PM

#

nah, that's what I was told about my Gear VR app and it passed tech review with flying colors

tired tree Oct 6, 2017, 5:31 PM

#

you had literally nothinf in that....

#

it was a landscape and some objects

mighty carbon Oct 6, 2017, 5:31 PM

#

I am going to have limited draw distance for objects

#

it's not like you can see 10 km ahead and see every detail

#

but, I guess I can only say if it would work when I test it

#

maybe it will work fine but look like p00p

wicked oak Oct 6, 2017, 5:32 PM

#

@mighty carbon if you want to do stylized, forward

tired tree Oct 6, 2017, 5:32 PM

#

very low poly would help

mighty carbon Oct 6, 2017, 5:33 PM

#

my main concern right now is ink outlines..

wicked oak Oct 6, 2017, 5:33 PM

#

becouse you can do fully custom shaders in forward, you actually get more flexibility on the materials

#

wich could let you do a proper toon shader

mighty carbon Oct 6, 2017, 5:33 PM

#

yeah, modeling character right now and polycount will be a way lower than on Mannequin

wicked oak Oct 6, 2017, 5:33 PM

#

@mighty carbon have you seen the guilty gear XRD talk?

tired tree Oct 6, 2017, 5:33 PM

#

lol

#

he isn't going to be doing that

wicked oak Oct 6, 2017, 5:33 PM

#

they talk about outlines in there

mighty carbon Oct 6, 2017, 5:33 PM

#

saw that, hell no...

wicked oak Oct 6, 2017, 5:33 PM

#

both external and internal

#

for internal they were painted on the texture

#

for external they did the oldest trick in the book. Render the mesh 2 times, the outline pass with the normals flipped

mighty carbon Oct 6, 2017, 5:34 PM

#

that's what I use now (from marketplace) and it works fine on Mannequin, but doesn't look nearly as good on lower poly models

wicked oak Oct 6, 2017, 5:35 PM

#

in guilty gear (tho they use ridiculously high poly models) they modulated it with vertex color

#

to control how thick it is

mighty carbon Oct 6, 2017, 5:35 PM

#

I might just get in touch with the author and see if they can fix it.. If I make ink hull manually, it should look fine.. I did it for Steel Storm.

wicked oak Oct 6, 2017, 5:35 PM

#

that way the outline is smaller or nearly nothing on some smaller details

tired tree Oct 6, 2017, 5:36 PM

#

which marketplace pack uses an inverted model?

sturdy coral Oct 6, 2017, 5:36 PM

#

what does flipping the normals do? was it to get a contrasting color and not just black?

tired tree Oct 6, 2017, 5:36 PM

#

most I know of were tracing outlines in the post process

wicked oak Oct 6, 2017, 5:36 PM

#

@sturdy coral so only back faces render

mighty carbon Oct 6, 2017, 5:36 PM

#

the problem is that it increases polycount and while it's not a big deal for a fighting game, it is a big deal for game with several characters in the view, level geometry and stuff

wicked oak Oct 6, 2017, 5:36 PM

#

there is a outline plugin that uses the duplicate model trick

#

i guess motorsep is talking of that one

sturdy coral Oct 6, 2017, 5:37 PM

#

and then they expand it out with a geometry shader (amount modulated from vertex color)?

wicked oak Oct 6, 2017, 5:37 PM

#

All Platform Outline Pack @mighty carbon ?

#

i bought it on sale like for 2 dollars just for the hell of it. I already had my own outlines, but i wanted to see how they implemented them

tired tree Oct 6, 2017, 5:37 PM

#

ah, k, yeah that would explain its name too

wicked oak Oct 6, 2017, 5:38 PM

#

as expected, such an "old" trick works literally anywhere

#

some of the fancy stuff in the marketplace pack is that they had "screenspace" outlines

#

wich just modulated the thickness with the world distance

mighty carbon Oct 6, 2017, 5:38 PM

#

@wicked oak yep, that one

wicked oak Oct 6, 2017, 5:38 PM

#

so they stay at a "constant" thickness

tired tree Oct 6, 2017, 5:38 PM

#

that is a problem with him wanting a fully outlined world though

wicked oak Oct 6, 2017, 5:39 PM

#

fully outlined world = postprocess

tired tree Oct 6, 2017, 5:39 PM

#

yeah

mighty carbon Oct 6, 2017, 5:39 PM

#

grass and foliage won't be outlined @tired tree

#

it would look really bad

tired tree Oct 6, 2017, 5:39 PM

#

wicked oak Oct 6, 2017, 5:39 PM

#

or dont outline the world. You can keep the characters outlined and the world "painterly"

tired tree Oct 6, 2017, 5:39 PM

#

grass and foliage not outlined but objects and buildings are?

mighty carbon Oct 6, 2017, 5:39 PM

#

but characters, landscape, rocks, etc. should be

wicked oak Oct 6, 2017, 5:39 PM

#

if you want to do like borderlands, (outline EVERYTHING) then its a postpro

tired tree Oct 6, 2017, 5:39 PM

#

....

#

going to really have to stlylize that then...

#

and you won't be able to use instances

granite jacinth Oct 6, 2017, 5:40 PM

#

What is "outlines" ? Like anime? Cell shading?

#

Or literally just object highlight outline?

tired tree Oct 6, 2017, 5:40 PM

#

that likely would end up MORE performance taxing than the post process, easily

mighty carbon Oct 6, 2017, 5:40 PM

#

Borderlands didn't have inner parts inked.. My old Phaeton game did. So preferably I'd like to get that look, but if not, oh well.

granite jacinth Oct 6, 2017, 5:41 PM

#

Man, I want a super optimized cell shader for VR.

#

If anyone knows of one, hit me up.

mighty carbon Oct 6, 2017, 5:41 PM

#

so I guess i have to use post process ink outlines and deferred renderer ?

tired tree Oct 6, 2017, 5:41 PM

#

or forward and FXAA

mighty carbon Oct 6, 2017, 5:41 PM

#

(FXAA looks like crap in forward)

tired tree Oct 6, 2017, 5:42 PM

#

there are some work around methods for the MSAA custom depth precision issues, but none that I was happy with

#

there is bound to be a good enough solution

sturdy coral Oct 6, 2017, 5:42 PM

#

for vr it would prob be better to have the flipped normal versions of the meshes baked into the meshes themselves

granite jacinth Oct 6, 2017, 5:42 PM

#

I'm a bit annoyed that most cell shader are only PP solutions

sturdy coral Oct 6, 2017, 5:42 PM

#

for less drawcalls right?

#

or maybe modify the engine's two-sided rendering

mighty carbon Oct 6, 2017, 5:43 PM

#

polycount will be unbearable most likely (and drawcalls will be through the roof?) with inverted mesh ink outlines

sturdy coral Oct 6, 2017, 5:45 PM

#

@mighty carbon probably yes if you want them on everything, not that bad if it is only characters and some other objects

tired tree Oct 6, 2017, 5:45 PM

#

motorsep you can enable specific objects to be outlined in a PP with custom depth btw

glossy agate Oct 6, 2017, 5:46 PM

#

Or you can go in there and hand paint the style.

A lot of the boarderlands effect is just in the texture map. Looks cool, but it will take some time

mighty carbon Oct 6, 2017, 5:48 PM

#

it won't look good as texture will be aliased and I don't think I want to do what Guilty Gear did

#

plus you still need procedural outline for the silhouette

#

@tired tree aye, I'll have to look into it

#

if I could use pp outlines with forward renderer, it would be sweet

wicked oak Oct 6, 2017, 5:59 PM

#

@mighty carbon are you sure you cant?

#

becouse the forward renderer still does a depth pass

tired tree Oct 6, 2017, 6:00 PM

#

its because of MSAA

#

the scene and custom depth values don't match up, there are some imprecision issues, likely from MSAA downscaling

#

so when comparing them you get artifacts

#

if he was doing FULL scene outlines it shouldn't matter

mighty carbon Oct 6, 2017, 6:25 PM

#

doesn't MSAA work based on actual geometry and thus all pp stuff is not being accounted for ?

#

what happens to pp stuff when using forward + MSAA? How does it get AA'ed?

You have to build it unless you downloaded the prebuilt binaries I think. I haven't tried pre built.

Double click the little vs thing above uproject then build when VS opens. Make sure you rename the folder to something shorter.

Guys, got a Rift earlier this week

#

I'm running into some massive camera jerking when I'm using the VR editor with motion controller

#

Lots of times when I move the controllers, the camera spazzes around

#

It's not the tracking, I assume, since it only does this in UE4

#

Any ideas?

#

(Tag me if you respond please <3)

#

Actually, after a little bit of testing

#

The issue seems to only/mostly appear when hovering over the foliage-mode panel with the controllers

#

Landscape etc are fine

#

Only foliage causes jerking

uneven moon Oct 7, 2017, 1:22 AM

#

Trying to create a bolt sliding mechanic but I'm not sure how to restrict its movement once it's grabbed to only back and forth so that the player can't just grip it and move it around in space

#

It has to stay inside the gun and move down a predetermined path but the player has control with their motion controller / hand

#

How do I restrict its possibility space?

sturdy coral Oct 7, 2017, 3:14 AM

#

@uneven moon I think several of the vr templates/plugins have examples

It just doesnt use a movement component

So you point+click and it moves there or

pretty much

But at any point in the tick, it appears to not be moving

Can you set it up to use the movement component but still have that functionality?

real badge Oct 7, 2017, 4:22 AM

#

uneven moon Oct 7, 2017, 4:22 AM

#

Getting the velocity now depends on exactly how you set it up

#

How is the movement handled?

real badge Oct 7, 2017, 4:23 AM

#

Its locomotion is just teleporting

#

and lerping between the points

uneven moon Oct 7, 2017, 4:23 AM

#

oh jeez

#

Yeah, not a good way to do locomotion even if it's seamless

#

You have no velocity

#

What you could do maybe is calculate the time taken from point A to B

#

And use that

real badge Oct 7, 2017, 4:24 AM

uneven moon Oct 7, 2017, 4:26 AM

#

Always a good idea to start VR projects in a blank project, setting up the basic VR pawn is very straight-forward

#

Then, if needed, use the templates as references for certain mechanics if you don't know how to produce them yourself

I just find Epics tempates to be pretty badly made

well slate is sometimes doing weird stuff, you just have to accept it I guess

tired tree Oct 7, 2017, 5:03 PM

#

@uneven moon Mitches examples, while well made for what they are, don't cover all of the bases.

#

you won't get a decent (attached) slider copying the logic

#

and it doesn't work entirely in relative space

#

so putting it onto a gun will bug out

#

its a great start though, you'll just have to convert the levers and buttons and slider to be purely in relative space

#

@real badge unless you are using the floating movement component you are going to have to do a lot of work

#

the character movement component only works with characters, so you would need to custom make one or use one of the already available plugins with one

real badge Oct 7, 2017, 5:19 PM

#

Ive got the movement component from the character class to work with VR with nearly no problems in the past

tired tree Oct 7, 2017, 5:19 PM

#

with a character?

#

because you will definitely have issues if you aren't having it follow or offsetting the collision

#

unless all you care about is the movement itself, at which point..floating movement should be fine

#

even then though, all movement components do it store a saved velocity, its not like you can't manually calculate that yourself

frigid kite Oct 7, 2017, 6:33 PM

#

Does anyone else sometimes have the vive teleporter teleport them to the origin, instead of to the selected location?

#

I did a check on all places that return or take the position vector, but nowhere in that chain does a (0,0,0) result occur

#

and yet, every so often I'm put there

tired tree Oct 7, 2017, 6:43 PM

#

if the navigation mesh check fails it returns an empty vector

#

so you should filter the teleport logic to fail if the return location vector is 0,0,0

#

the node isn't implemented correctly, it only returns false if the navigation system doesn't initialize, it still returns true if it just couldn't find a valid location

uneven moon Oct 7, 2017, 9:23 PM

@tired tree I'm still fairly new to UE4 so I can only understand about half of what he did. Someone else suggested doing this via a timeline somehow, as in having the motion controller, once gripping the bolt, adjust the float when travelling from A to B on the X axis but I don't imagine how that would work. Someone else said to clamp the relative location which sounds like what I need

@uneven moon What are you doing for your regular bolts on other guns?

I have my bolts working, but havn't figured out the 2 part bolt action yet ie. have to lift before you can slide back. I just moved onto other stuff for now but if you figure it out let me know

tired tree Oct 7, 2017, 9:33 PM

#

@uneven moon clamping is really really easy, record initial hand position and get (currentHandPos - InitialHandPos) each frame and set the slide to that delta value from its original location, but Clamp(Minlocation, Maxlocation) the result

#

you can dynamically change min/max location to handle things like changing allowable directons

#

rotation is another matter though

How do I get a component's location relative to this red line I've drawn? (There is a spline there)

#

Motion controllers need to be able to move from point A to point B but getting relative locations doesn't account for room-scale

glossy agate Oct 8, 2017, 4:17 AM

#

It does. It's just relative space of your gun BP

uneven moon Oct 8, 2017, 4:17 AM

#

@glossy agate this is inside my VR pawn BP, the gun is attached to my hand, it's not a separate component that I pick up

#

glossy agate Oct 8, 2017, 4:19 AM

#

gonna be cleaner to put the logic in a separate gun BP. Will save you some headache.

uneven moon Oct 8, 2017, 4:20 AM

#

but even then, I would need to calculate the motion controllers vector locations

#

so it doesn't change much from how far in I am now

#

if I strafe left and right, the motion controller's "locations" change

#

both in world and relative

#

even if the controlls are still in my hand, not moving

#

seems impossible

glossy agate Oct 8, 2017, 4:23 AM

#

It does. When you grip through a BPI you just set off a tick event to match the world location of the controller along just the one axis and use it to set your relative location of the slider in gun BP.

wicked oak Oct 8, 2017, 12:25 PM

#

@uneven moon you need linear math

#

i actually have that kind of thing

#

a line is done from 2 sockets, or from a socket + an offset

#

once you have a line, you can use math to find the closest point to that line (in fact ue4 has that function), then you snap the position of the hand there

#

if there is a lot of offset, then you detach the hand from that

tired tree Oct 8, 2017, 2:03 PM

#

think he is more confused about relative space than anything else

hi, is there an existing way of getting a loading screen with a dynamic element? I was thinking of streaming in a loading screen level, and showing this while loading the next level, but if something already exist, then I'd rather not.

tired tree Oct 8, 2017, 2:04 PM

#

@uneven moon ifyou are holding the item and strafing left and right, both the held object and your other hand get the same offset, you still have the same relative space coordinates

#

You need to inverse transform the motion controllers location by the guns transform

#

either both in world space, or both in relative space to the actor

#

that provides a location vector of the second hand relative to the gun

#

@wicked oak splines also offer closest transform to point as well, so you can literally draw out paths to follow

#

including built in rotation

The bolt moves back and forth but a lot faster than my hand even though from point A to B the timeline moves from 0 to 1 and the bolt is moved from A to B depending on that value

Hello, am running into some trouble. Am using the VR template in Unreal and added a socket to the bone of the VR hand which comes in the template.

Copied over the cube pickup BP and replaced it with a pistol mesh. Tried attaching the pistol to hand on pickup and snap to target but issue is the pistol always ends up in a dfferent location as compared to where the socket is at.

noble charm Oct 9, 2017, 3:44 AM

#

@pale whale is it different depending on how you pickup the pistol

pale whale Oct 9, 2017, 3:45 AM

#

@noble charm no, its always in the same position regardless of how i pick it up

noble charm Oct 9, 2017, 3:45 AM

#

Most likely due to the centre of the pistol mesh being off

#

Have you looked at that in the blueprint

pale whale Oct 9, 2017, 3:47 AM

#

I've tried attaching it to the mannequinHand_Right skeleton mesh in the level blueprint and it snaps correctly to the socket in the level.

cant get it to attach properly on my hands in VR

Is there a difference between the two methods you are using to attach

uneven moon Oct 9, 2017, 7:05 AM

@pale whale Did you solve your problem?

#

I ran into an issue like this once because the pivot point for my mesh was not centered. Import your gun mesh into another software and make sure it is at 0, 0, 0 then export it as an FBX and re-import into UE4, then try to attach it.

pale whale Oct 9, 2017, 9:53 AM

@uneven moon I managed to solve it by passing over the skeleton mesh component as part of the interface component being called. sorry for the late reply.

anyone noticed that if you have two or more materials on a static mesh, then the physical material returned from ie. a trace does always return the phys mat from index 0?

The console command r.ScreenPercentage is crashing in VR for some of my users, has anyone else experienced this?

eternal inlet Oct 9, 2017, 12:39 PM

not that i've heard of, is it possible to get their log from them?

#

often there's some info about what happened prior to the crash in the log

tired tree Oct 9, 2017, 12:44 PM

how high are they setting it? might be using too much VRAM

pine nimbus Oct 9, 2017, 12:49 PM

#

Absolutely nothing in the logs except it ends after the r.screenpercentage command @eternal inlet, and setting it to anything crashes, even lower values than the default @tired tree

Vanilla 4.17.2

pine nimbus Oct 9, 2017, 1:31 PM

Turns out the crashes are resolved if they use a .pak unpacker, which is for modding / ripping game assets

#

Very strange bug

pine nimbus Oct 9, 2017, 2:05 PM

#

Packaging a build without a .pak files resolves the issue. Has anyone else com across anything like this? Where the .pak files cause issue?

pine nimbus Oct 9, 2017, 2:20 PM

Okay correction, using compressed .pak file seems to be the issue, not the .pak files themselves

Anyone experience black BP viewports and thumbnails when using forward rendering?

frigid kite Oct 9, 2017, 3:31 PM

@tired tree Remember when we talked about teleport sometimes still going to origin, and you having fixed it by checking the projected nav mesh result because the implementation by Epic is incorrect?

tired tree Oct 9, 2017, 3:31 PM

#

yes

frigid kite Oct 9, 2017, 3:32 PM

#

Turns out, you can still teleport to the origin despite that check, because of the delay between the initial action and the actual teleport

#

during those frames, the position is still being updated if you move the controller slightly

#

but the bool for valid location is no longer checked once the delay is started

tired tree Oct 9, 2017, 3:33 PM

#

mmm, should be storing the last location then

#

last valid that is

frigid kite Oct 9, 2017, 3:33 PM

tired tree Oct 9, 2017, 4:28 PM

@frigid kite I fixed it in my template, obviously if someone is basing off the Epic one it would still have the issue.

sturdy coral Oct 9, 2017, 5:01 PM

#

@pine nimbus you don't want to use compressed pak files anyway.
I think it interferes with steam's delta compression

#

unless you are trying to squeeze on mobile below a certain install size I would avoid it, steam will compress the download on the fly anyway

#

and delta compress updates

pine nimbus Oct 9, 2017, 5:06 PM

#

Interesting, thanks for the info. I found if I archive the uncompressed packaged build using winrar, it ends up smaller than when I archive the compressed packaged build, so I guess it's related to what you said about Steam's compression. If it can't compress it as effectively because it's already been compressed by UE4. Space taken up on harddrive is a non issue for my game so it's good to know 😄

#

@sturdy coral

sturdy coral Oct 9, 2017, 5:16 PM

#

yeah steam will compress the download stream, and if you make a small update to something within the .pak users will only have to download a small delta

#

but if the .pak is compressed I'm pretty sure they have to redownload the whole .pak

full junco Oct 9, 2017, 5:19 PM

frigid kite Oct 9, 2017, 8:33 PM

4.18 just has it, I believe

#

so, not if you use that

#

I played with the 4.17 custom engine build for ARcore (well, I built the Google sample), and I must say I was rather disappointed

#

tracking is quite unstable, the surface detection is far from robust

#

Vuforia's extended tracking works at least as good, if not better, and that's been out for several years

well arcore kinda is new too

frigid kite Oct 9, 2017, 8:50 PM

Is there no way to 'zoom in' with a 2d scene capture? Trying to create a scope but it shows things the same size as they are when seen with a naked eye (it's a sniper scope)

glossy agate Oct 10, 2017, 12:23 AM

#

I think you just the FOV

uneven moon Oct 10, 2017, 12:26 AM

#

Naw that doesn't affect zoom

#

I read that this can be done in VR by modifying the render target

#

Trying to 'scale up' the texture

glossy agate Oct 10, 2017, 12:52 AM

#

I have a working scope. I'll check in a bit.

#

But yeah it's 2d render target. Gotta figure out how to do the parallax effect still though so it feels like a real scope instead of a little screen.

#

FOV was just for the capture to fake a zoom and you probably have to scale it up in the mat

sturdy coral Oct 10, 2017, 1:20 AM

#

FOV totally affects zoom

dusk vigil Oct 10, 2017, 2:03 AM

#

I thought a scope should optimally be an independent custom camera render

#

Therefore with all the bells and whistles ie custom fov, dof, whatever

#

Tip for scope : don't let the eye see it unless it is right over it, like a real scope, it should just be black unless lined up

#

It's not about parallax or whatever. It's about not being able to see through it unless lined up very precisely

sturdy coral Oct 10, 2017, 2:15 AM

#

You can sort of get that effect automatically with parallax though

dusk vigil Oct 10, 2017, 2:15 AM

#

If you look at a scope from say 10 cm away at 45 degree angle, you see nothing period. black

#

If you show anything, you break realism

sturdy coral Oct 10, 2017, 2:16 AM

#

Yeah it won't be as extreme, but if you look off angle with parallax mapping, you will also see black

dusk vigil Oct 10, 2017, 2:16 AM

#

unless it's a scifi scope monitor

#

If you want to go for realism, just fade to black if eye is not lined up. Easy and works

sturdy coral Oct 10, 2017, 2:17 AM

#

Fade isn't enough, it will look flat even if only to one eye

dusk vigil Oct 10, 2017, 2:18 AM

#

Yes. sniper scopes look flat, because you look at them through one eye only

sturdy coral Oct 10, 2017, 2:18 AM

#

You need it to move when the angle of the gun to the eye changes, which parallax gets you

dusk vigil Oct 10, 2017, 2:18 AM

#

I dont understand why you should need to add extra cheats, if you are modelling the scope correctly

sturdy coral Oct 10, 2017, 2:19 AM

#

It isn't quite the exact effect of a real scope, but fade to black definitely isnt

dusk vigil Oct 10, 2017, 2:19 AM

#

question of what the scope looks like lined up in use
question of what the scope looks like when you are not looking through it

#

which one are we talking about?

sturdy coral Oct 10, 2017, 2:20 AM

#

The transition between the two

dusk vigil Oct 10, 2017, 2:20 AM

#

Easy and cheap is the fade to black, I dont see why you would want to make it more complicated than that. A fellow team made this system, and it was very convincing without any more extra work

#

They also had a fully physical rifle with tracker puck

#

Very nice. The weight of the gun really made it feel good

#

The scope was kept black until pretty much perfectly lined up, much as real scopes are

sturdy coral Oct 10, 2017, 2:25 AM

#

Yeah, real ones transition pretty suddenly and have a pretty narrow sweet spot

dusk vigil Oct 10, 2017, 2:25 AM

#

Yes indeed.

sturdy coral Oct 10, 2017, 2:26 AM

#

On low power ones you can definitely see the keyhole kind of move into place with a sort of parallax though

dusk vigil Oct 10, 2017, 2:26 AM

#

Why bother spending too much extra effort on such niceties, when one should focus on actually surviving in this world

#

You are not going to make extra sales by spending a day or two on that

sturdy coral Oct 10, 2017, 2:27 AM

#

It's basically just a parallax material node and a sphere mask node

simrak...its pretty common to use parallax in VR for scopes

dusk vigil Oct 10, 2017, 2:30 AM

#

Will be keep to try it out. Yeah, I was not arguing that, more the amount of time spending on polish of view outside of scope -> to targeting

tired tree Oct 10, 2017, 2:30 AM

#

?

#

its a core component of a game usually if they have scopes

#

why the hell not polish it

sturdy coral Oct 10, 2017, 2:30 AM

#

I feel like for example mirrors in project cars

#

Would look 20x better with parallax to fake the 3d

#

Instead of looking like screens

dusk vigil Oct 10, 2017, 2:35 AM

#

I have not investigated parallax effects in this area. Will look into it. Still feels like overengineering. Mirrors are mirrors, scopes are scopes. Is the added parallax effect doing something to compensate for what the camera cannot do?

sturdy coral Oct 10, 2017, 2:35 AM

#

It is under engineering, instead of trying to get a perfect stereo mirror with realistic distortion or whatever

#

It would be faking some stereo with parallax

#

To look better than what they have: flat and looking like a screen instead of a mirror

dusk vigil Oct 10, 2017, 2:36 AM

#

I can understand stereo necessity in mirrors, but since scope is fundamentally a one-eye thing, why on earth go for stereo? I dont understand that?

tired tree Oct 10, 2017, 2:37 AM

#

it makes the scopes significantly better

#

....

#

have you used the scopes in H3VR?

sturdy coral Oct 10, 2017, 2:37 AM

#

It is a one eye thing, but you are moving it with your hand independent of your eye and if you don't see some effect from that it can feel flat

dusk vigil Oct 10, 2017, 2:38 AM

#

No, admittedly I am not a shooter fan as such

#

I though the camera of the scope would be configured for whatever is needed. Time to download Horseshoes and really look at it close

#

Still a question to make things clear : you only look through the scope with one eye, yes or no?

#

even in VR

tired tree Oct 10, 2017, 2:40 AM

#

straight texture render lacks depth

and high powered real world scopes have parallax in them

to the point where you have to learn to account for it

it gets you that type of effect

#

distance and angle based parallax to line up

sturdy coral Oct 10, 2017, 2:46 AM

#

The main difference I think you will see is if you move your eye closer to one that is just a scene capture painted on the surface with blackout, you see the same fov as if you move your eye farther back

#

With a real scope as you move your eye back farther, the image doesn't really grow or shrink much, and just gets cropped in more by the sides of the scope

dusk vigil Oct 10, 2017, 2:47 AM

#

I get what you are going for, but still think it is wasted effort unless you are making a pure sniper game

These friends of mine with the tracker puck rifle tried to sell their rifle range prototype to a gun manufacturer. For them it wasnt really a dealbreaker of realism, it was more that they were just so used to firing real guns they could not see the point of a simulation in the first place, at least the old school dudes. Apparently some of the younger ones appreciated it

tired tree Oct 10, 2017, 2:53 AM

#

there are a lot of tracker puck rifles out there

#

pretty sure the AIM controller is going to be more popular than any of them ever will be too, due to first to real market and not requiring additional unavailable hardware

dusk vigil Oct 10, 2017, 2:55 AM

#

Yeah, at first I was dazzled by the idea of a puck that could serve many purposes, but in the end it seems like it may be a pipe dream. Though it might still work out, who knows

sturdy coral Oct 10, 2017, 2:56 AM

#

It just needs to be like $20-30

tired tree Oct 10, 2017, 2:56 AM

the tracker modules themselves have a real use, built into hardware itself

#

but the vive trackers are likely DOA, considering any company can make the same but cheaper and smaller with the LH 2.0 tracker kits

sturdy coral Oct 10, 2017, 2:57 AM

#

Yeah I hope 2.0 really brings down cost

#

Someone said the photodiodes plus the little driver board on each are over $1 even in bulk

#

Though I don't know how they knew the bulk price, just saw it on reddit

yeah, but mass production gets deals on that

dusk vigil Oct 10, 2017, 3:04 AM

#

Just so I get that parallax thing straight, sorry if I feel obtuse : we are talking about that black space, the scope body, not the view through the scope? ( Sorry to get back to that, don't really want to spend too much time on it but could not help investigating a bit more )

#

I think I understood it right but wanted to double check

#

Aaanyway. What would you do with a thousand pucks?

for a 60k dollar camera

#

that is in an incredibly niche market

#

it had absolutely NO chance of ever succeeding

#

like, even if VR went to smartphone level right now, it STILL would be a bad idea

#

assuming a 20k profit per camera, wich is really high end, and the employees getting 2k dollars per month (wich is very low end) then they would need to sell 31 of those cameras a month

#

a more logical cost would be 10k profit per camera, and 4k dollars per month on employee, wich means more than a hundred of those cameras a month

how the fuck do you expect to sell so many of such a niche expensive as fuck product

@mighty carbon oh man I finally found it! Unreal's Documentation is quite outdated for that.
to get D-Pad Inputs you have to use "Motioncontroller (R) Thumbstick Up/Down/Right/Left"

mighty carbon Oct 10, 2017, 3:41 PM

#

yep, so I did.. My issue was that when I'd press d-pad, I get 3 events happening simultaneously - touchpad touch, touchpad press and random D-pad press (I used keyboard input node that returns any key/button press). The main problem was that when I used Motioncontroller Thumbstick, I could never guess what is being pressed. So if I pressed exactly on directions, it would work as expected. However, no one will do that and user would press Down for example, but a bit closer to Left or Right (physical location of the finger). And UE4 would return 3 values - Down/Right/Up..

#

that was in 4.16.2 though

@timid anchor motion controllers can't collide with stuff, they are always exactly where your hand is

little nacelle Oct 10, 2017, 6:12 PM

#

@full junco yes, but the mesh attach to it can theorically collide, I tried to just set the location and rotation of the hand to the motion controller's ones with sweep enable, but It just takes the root bone of the skeletal mesh to do the sweep

full junco Oct 10, 2017, 6:14 PM

#

if you make the mesh collide, it won't feel good because it will be at least 2 frames behind the motion controller component

#

you can do it with physics handles, but you shouldn't do it for the motion controller mesh

tired tree Oct 10, 2017, 6:16 PM

#

he can manually sweep it from last pos to current after the motion controller ticks

#

it would only be about half a frame behind visually

#

which is still a lot, but all of the game logic is half a frame behind or more visually

full junco Oct 10, 2017, 6:17 PM

#

hm? a sweep happens on the game thread, the GT is 1 frame behind the render thread, and the render thread is usually 1 frame behind what you get with the late update, so it would be 2 frames behind

#

or 1.5

tired tree Oct 10, 2017, 6:18 PM

#

render thread is not 1 frame behind late update...

#

late update is applied late in the frame on the render thread.....

#

based on game threads reported pos

full junco Oct 10, 2017, 6:19 PM

#

late update is at the end of the render thread, and I think you could say that end of render thread is 1 frame later than start of render thread. or half a frame

tired tree Oct 10, 2017, 6:20 PM

#

its not 2 frames behind at all.....

#

its significant sure...but all game logic is behind the render thread late update anyway
