[silver orchid]

got two of them on order and another tracker because why not?

[waxen oxide]

@left sierra Ideally pixels are rendered 1:1, scaling is undesirable. For professional LED setups, you're typically looking at a setup where you have an UE render engine -> Scaler (Something like a Barco E2, https://www.barco.com/en/product/e2-gen-2) -> LED processor (Something like a NOVASTAR) -> pixels on LED.

[devout lintel]

anyone have some experience with web remote control?

[left sierra]

i know led walls are made of panels. when you say their own GPU what do you mean? like some driver that controls them or an addon PCIe graphics card gpu?

[left sierra]

so from all that you people tell me, the setup can become quite complex. where can i look more into it? is there a guide or something? i thought those virtual production field guide by epic vol1 and 2 would be like guides or something but they are not very helpful

ok the budget may be prohibiting for me alone, but if i am to approach some green screen studio or some rental house with a proposition to invest in a virtual production studio, i cant be that uneducated about this. but where can i learn more?

[waxen oxide]

I've worked fulltime in virtual production for five years, I'd be happy to answer questions! There's not much in regards to A-Z "Manuals" that I'm aware of, because there's hundreds of different technologies, lots of possible workflows/usecases, as well as generally way more fields of expertise than a single person would be expected to cover singlehandedly.

If you are looking to just get into virtual production, a greenscreen for virtual studio, or just plain AR, with a budget tracking solution, is going to be your best bet.

If you are looking to use it for live broadcast, you suddenly need to start worrying about different signal rates, color spaces, genlock, and all the broadcast engineering that goes into fitting Unreal into traditional video pipelines, which is a whole different beast.

[wraith cosmos]

Are you trying to setup a rental house for shooting live production?

[left sierra]

yes thats about it

personally i care most about having a led wall/room and a tracked camera. not for broadcasting. i have worked with green screens and i dont like the workflow. btw film and video are intense hobbies of mine, my work is in architecture and construction. so anyway i see two paths, either invest some of my money and also look for interested investors to set up a virtual production studio

or i approach existing studios to talk about investing in virtual production using unreal engine. (in that case maybe they will be interested in broadcasting)

either way, i need to learn many more things about this and im looking for info about it

[wraith cosmos]

Green screen might not be as bad as you think it is. When you composite the real life keyed live footage into the unreal engine, the unreal engine lighting takes over and you can light the subject in unreal engine.

So use a hybrid of green screen and projector depending on how reflective your subject is.

I would recommend spending about 5-10K usd and start really playing with this stuff so you can figure out what to scale up to a rental space.

You would need an onsite UE4/UE5 person to oversee all of this and make sure things are working properly, lighting, scene, etc. I would also assume anyone who spent the time to learn all of this is busy working on their own projects.

[left sierra]

yes i have to make some tests thats true. green screen spaces are existing and quite popular so there not much new i can do in that field.

Hello! Is there a way to jam the timecode for unreal, and after the sync the engine provides it's own timecode? Or the BMD timecode provider needs continous video feed with timecode embedded to work correctly?

[solemn nova]

Question
Can someone recommend me a Cryptomatte or Alpha Matte tutorial? I tried the tutorials from Winbush and Faucher, but they do not cover the post production. I can't get a clean alphamask, i think im doing something very wrong.

[zenith cove]

Are you unable to get a clean alphamask out of UE4 or in general?

I think there are some cryptomatte sample sets somewhere, you could try if you can open those

[solemn nova]

Yeah I am exporting a clip with .EXR data and inside After Effects i use ColorKey to key out the part i dont want. Then I combine the two layers with the mask and the original object, then i key it again to remove the background. But i keep getting aliasing on the edge, i tried shrinking the mask and feathering it but somehow it just doesnt look right.

Normal

CryptoMatte

and then keep getting this result

[zenith cove]

Hmm, this feels familiar from my distant past in a VFX house. Is there motion blur or depth of field on? How does it look in motion? Maybe you can get away with a non-pixel perfect mask

If I remember correctly, we used to deal with it by adding just a bit of gaussian blur to the mask

(we did a lot of bodging)

[solemn nova]

This segment is almost no motion, a rotation of maybe 3degrees over around 15 seconds

It's a bit wierd because the rest looks fine

I will try the Gaussian blur

and otherwise i'll just mask it with some fake Bokeh, but I want to learn to use the Matte's correctly for future use.

[zenith cove]

It's a Blender discussion but this seems close to your issue: https://blenderartists.org/t/cryptomate-matte-edge-imperfection/1189344/22

[solemn nova]

It does only cover Blender indeed, but i'll give it a read on my break

Thanks for trying to help

[sly wing]

hi! can i pls ask is there anyway to convert a meta human into an asset that can be used in unity? Thank you! Or is it easy to export a 3d world made in unity into unreal engine? Thank you!

sorry about this wishful thinking haha i got asked regarding metahumans avatars visiting my VR world today (https://www.unrealengine.com/en-US/metahuman-creator) and as far as I can tell this will only work if I set it all up in unreal engine/ maya?

I have so far only used unity as a game engine

[zenith cove]

Doubt it and you will more than likely run foul of licensing

[sly wing]

thanks!

Hello I have a question regarding Switchboard and nDisply.
When I start nDisplay with switchboard my main monitor is used to display nDisplay and not my preferred output device (a beamer for testing). Here is my question where can I change this so that nDisplay is displayed on startup on my preferred output device?

thanks in advance

[solemn nova]

That's not how cryptomatte is supposed to be used

It's not a clownpass

[solemn nova]

do you have a sollution or refrence where i can find some information?

https://www.youtube.com/watch?v=_cOG53NWJj4&ab_channel=JakeInMotion @solemn nova check this out. Think you'll be pleasantly surprised on how powerful it is.

[solemn nova]

thanks got it, was just the selection and it creates a matte. very nice

much cleaner than my jank sollution 😄

[zenith cove]

Oh I didn't realise you weren't using the CryptoMatte plugin, sorry mate

[potent plover]

anyone ever use large PNG sequences and have issues with them dropping frames when rendered out in movie render queue or sequencer

[onyx flume]

Go to Project Settings and search "cache" and look for IMG Media caching settings. I set the Cache Behind Percentage to 0, Cache Size .25, Cache Threads 2 and Global Cache Size to 24. See if that helps, you should get better playback in Editor. It's only when I start playing 3 or more media tracks where it'll start to stutter. But out of MRQ I don't get frame drops

In the documentation it also recommends using EXR sequences vs PNG, but I've worked with both

[safe apex]

is there a quick/easy way to add "fly camera" controls to my cinecamera? I feel like someone must have already made a BP for this, or I am missing something, but I can't find anything and just want to be sure before I sit down and write a BP that does that

Hey everyone! Just wondering if anyone has been using Composure with Lumen? I've noticed that the scene capture components seem to default to Screen Space GI even though Lumen is set (both Early access and Preview). Wondering if this is expected behaviour or if I'm missing something? If so, is there a way for Composure layers to work with Lumen at all?

[formal star]

Has anyone any idea why is my UE 4.27 live production project using bm decklink for capturing and output and vive trackers for camera tracking, when i start the project using simulate button to get the traking data, my PC usb ports are disconected then reconected in loop so the whole pc is unusable. Steam Vr is working ok outside UE, UE working ok and capture and output working perfectly. Only when is start the project with simulate button to run the blueprint i have on my camera everything goes bad.

Hello,

Is there a way to get working stream from RTSP protocol, where URL has login and password and show this stream in UE4 ?

[loud viper]

Hi everyone. Question about chroma key.

I've got a small green screen, tracker on real camera, and composure plugin for chroma keying. I have an issue: when I'm using it for a live stream part of my room can be noticeable when camera is moving. Is there any way to mask out everything in a shot, except me? For example: I'm standing "in a forest" and when camera is moving, there should be a forest, but instead I see my room.

Cheers.

Someone know how to syncro play composure with sequencer? I want to start at the same time I press play in sequencer both animation and video in media plate..

[faint crag]

Hello everyone. I am getting in to virtual production for making short films. About a year ago I did a bunch of research on the process, and I'm currently getting back up to speed to learn UE, virtual production techniques, and make a small project to test things out.

I want to build a virtual camera rig using a HTC Vive wand for virtual camera tracking (I already own a HTC Vive), and attach a mobile device/screen to use as a viewfinder/viewport/monitor. The last time I checked out how to stream/sync a camera to another device, Unreal Remote app was the better (only?) option but was iOS only. I have a Samsung Galaxy Note 9 and am relegated to Android options for now.

I have reviewed documentation and I can't seem to find a way to stream a camera from UE to another device without Unreal Remote, and an iOS device.

Maybe there is a different feature I should be considering? There is an Android app on UE marketplace, but it doesn't sound reliable, and there is no demo.

I also have an ASUS ultrabook, which is light enough to consider for building a camera rig, but if I can use my Samsung Note 9 would be much better (and much easier to mount safely for quick motions).

I'd appreciate any insights or assistance 🙂

[faint crag]

Hello. I don't have the expertise to troubleshoot Lumen, but William Faucher covered off some pros/cons and caveats with using Lumen. Check out this video.

[floral yarrow]

Hi Everyone,

I have this idea, and I would like to know if it's doable and if anyone can point me in the right direction.

I would like to shoot a video of me talking and create a 3d version me, then put this version in an environment in unreal engine, and then use multiple cameras in unreal engine to have a "virtual studio with multiple cameras".

I don't want to create a character, I want the real me inside the environment.

Is that possible ? If yes, how this can be done? Either for creating the 3d version of me and on adding it in unreal engine.

Thanks in advance,
Martin

I'm experimenting with nDisplay on one machine with 2 displays. I can't get the nDisplay configuration to actually display to both monitors.

The configuration has 1 Cluster with 1 Node and 2 Viewports that are set to the resolutions of the monitors.

When I launch the nDisplay config via Switchboard (UE4.27), I only get a result on the monitor that is selected as "main monitor" in Windows (Operating System) display settings. But It does not show one of the configured viewports either, it shows part of the outer "Node" or "Host" element, as fits on the screen.

Can't find any setting for Display index or something like that. Though they explicitly say, in the DemoVideo videos of Unreal Engine, that this is a valid use case.

What setting am I missing?

[shy bridge]

Have you tried running the nDisplay template with the provided dualscreen config?

[green kiln]

@shy bridge Thanks. I actually had the project open two times now, but missed the DualScreen config. Still it does not work (correctly).

I have a FullHD Monitor (left) und WQHD (right). Just running the Config does not work, cause it is configured for 2 WQHDs.

Setting the left monitor to FullHD in the config, does not work either, as the Node is 1440 high. It starts displaying on the Right monitor.

I got it working by using two nodes with one Viewport each, instead of one Node with 2 Viewports.

Another big issues I noticed, was that the left most monitor in the Setup needs to be the main monitor (Windows monitor config), otherwise it still starts displaying on the right monitor, but does not wrap around to the left one.

[shy bridge]

I think nDisplay doesn't work with negative screen coordinates, i.e., the main screen must but the leftmost. But I'm not too sure about that, I only encountered a bug like that on one cluster.

[green kiln]

I did not find any mentions on that restriction. Was 4 hours of trial and error

[shy bridge]

Same here 🙃 I think in 4.26 it straight up crashed, so I'm not sure whether it's an improvement or not. Who knows, maybe UE5 will fix this.

[green kiln]

Its Unreal

[untold furnace]

Would anyone know why PNG has no alpha option, despite my alpha setting being set to linear color space only

Ah I just realised, it is working but they changed needing it as an option (shrug)

[shy bridge]

Has anyone ever had someone with a VR headset inside an nDisplay cluster? One of my (weird) use case needs that, and I'm wondering what's the simplest way to get that done. I'm pretty sure that you can't just configure a "VR headset" node in a cluster, so I'm thinking setting up a multiplayer thing, with the nDisplay master and the VR headset being two clients. But the question then becomes: has anyone done nDisplay multiplayer? Is that even possible? Anyway, all pointers are welcome.

Hey does anyone know how to use Live Link as the default walking/movement input for the ThirdPersonBP?

I am trying to use PNLive Link to power the thirdperson character's movement. However whenever I run this current BP setup, the character doesn't play any animation.

Anyone know how I can increase the resolution of a live camera feed? Seems like it just matches the object dimensions

[sterile cape]

are you using a RenderTarget2D?
Increase the resolution of that texture thingy

the sheer size in pixels of the texure

if you have it in an asset, double click the asset and look in the right sidebar

[plush walrus]

Oh yeah that worked! Thanks a lot!

[oak smelt]

how do you deal with character hands going through static meshes when using mocap?

trying to have a character type on a keyboard but when it does, his hands go through it

is there a way to use collisions?

[hidden ermine]

Hey y'all have a question about image sequence being used to composite a scene. So the scene and its animations work just fine but the green screen image sequence lags and seems to jump. Is there anything I can do to smooth that out? I'm creating a clean green background in premiere and then putting out an image sequence of PNGs. There are 505 images in this sequence. I've increased the poolsize to 4000 to over compensate for the megascans and hoped it would also help with the image sequence but so far no dice. I'm using 4.27. Any ideas what I can do to make the image sequence run more smoothly?

[hidden ermine]

Hey so, i fiddled with some speed settings as I edited clips together in Premiere and got the dialog and scene to match up a little better but I can't do that all the time. Also just wondering, since I know its still pretty rough, what would you recommend I focus on to up my game. https://youtu.be/zx1UQGqz1zA

[zenith cove]

Heh, cute

You got some leeway to rotate the camera a bit in the beginning

The pitch and yaw is static throughout the whole clip which makes it a bit stiff. You can play aruond with that and then ease back into the settings you need when you approach the actress

[zenith cove]

Are you compositing in UE4 or does the image sequence contain an alpha layer?

I think the biggest issue you encounter in that regards is that loading videos and scrubbing can actually be rather resource intensive, enough that a noticeable offset can occur

I've used the HAP Codec in the past https://hap.video/. It's a codec that loads footage into GPU memory and is a fair deal more responsive and has built-in support in UE4

If you're using a MediaPlayer asset in UE4, I recommend looking into its OnMediaOpened event and hooking your logic to that. That way for example, you can start your scene only your file has been loaded into memory

[hidden ermine]

So I clean up the background in Premiere then import a PNG image sequence. Then I have a chroma material to remove the greenscreen in UE4. Then I export an AVI out of UE4 and edit all the clips together in Premiere and add audio.
I worked with MP4s first before moving to image sequences. I had an issue where a random thumbnail would show up and then it would play the video. I was also trying to kick off certain events/animations when the image sequence reached certain points. Have you had a similar issue of an odd thumbnail showing before playing the video with the HAP video? I'll experiment with it either way. Thanks much for your Help!

[zenith cove]

A PNG Image Sequence can be surprisingly heavy to run, as the computer needs to open the file, decompress the image, load it to RAM, display it and then remove it and start the next frame

Generally speaking, your computer should be able to handle that but once you got that with a VP set-up in UE4 with a very low margin of error

Same with MP4s. These formats are designed to be light on diskspace

I havent' had the issue of an odd thumbnail yet though

[hidden ermine]

Cool coo, I'll give it a shot. If it can launch the video at the right time I can work out the other timed animations.

[hidden ermine]

Would it be better to jump into UE5 for virtual production or do you feel that UE4 handles it about the same?

[zenith cove]

You know, usually I say, wait for UE5 release version but for VP it might be interesting because of its higher visual quality

I would check your pipeline and see whether it supports UE4 Early Access yet

[sour rapids]

Hi guys. I just started using UE for real time green screen. Does anyone have any idea how I can add shadow to foreground objects using composure composite?

[sour rapids]

Have you figured this out yet? I tried setting body physic spheres and collision but no luck.

Anyone have any experience or ideas for making video from an nDisplay setup? Would be great to be able to make my planes in nDisplay and then render out videos for each. Capturing realtime is going to be a pain!

[digital charm]

Does anyone work with Take Recorder's blueprint functionality here? I've been digging into the source files to automate the process, and am curious if anyone else has looked into that. Online, most resources I've seen are just on mapping a gameplay button to hit Record.

Lol any tips or anyone come across the same issues?

[digital charm]

When working with level streaming, is there a way to change Unreal's default to "Always Loaded" instead of Blueprints? We use sublevels just so we can have multiple artists work on the same map, but it means often dragging in levels and always changing them manually to "Always Loaded". It's not a big deal, but can be a pain when rendering and you forget that one sublevel is still blueprint streaming (and won't render).

Hello 🙂 I was not able to get the timecode directly from Xsens to unreal, but we were using tentacle sync and got the timecode information both to Xsens and Unreal from it.

[atomic flicker]

interesting, I am looking at tentacle sync and peel capture as possible solutions as I am trying to bring together body/face/audio to test out syncing in sequencer that way. Would you be able to share what your timecode integration with xsens look like in sequencer?

No, static built lighting.

I could always not building lighting, but it gets annoying when adding new characters and having to remove the unlit material to rebuild.

Hi can someone explain me how to use a source controle, i wanna do simething with a friend and i cannot download perforce and prefere to use github but even if i use lfs it dosent work and tell me i have more than 100mb

[viral summit]

Github ain't good for source control as you will deal with a lot of binary files

Perforce or Tortoise should be your go to

[copper warren]

I don't remember exactly, but I think I didn't find a solution and have to use a classic sky

[copper warren]

You can take a look at Plastic SCM which looks good for a small team

[humble ether]

Ok i will try

[humble ether]

Can someone tell me if perforce need a proxy to work or something like that and if someone have a good video to send me of how to setup all that and to connect to the project

[pallid heath]

perforce has a proxy server called p4p. but that's used as a local file cache for remote servers, to save on egress charges and download times. it's typically something you setup in an office. as for questions about perforce and version control I would direct them to the #source-control channel

[leaden mauve]

Hi folks. I'm in the process of putting together a small green screen virtual production setup. I'm trying to nail down my process a little as well as land on some hardware specs for a pc. Shopping around has presented a pretty wide array of costs. I've been using my personal Ryzen7 with an rtx 2070 super and it has worked ok but I don't think it's going to be beefy enough when we start doing things in UE5. Any recommendations?

[white atlas]

Hey folks. Charles from Voltaku here. We presented at GTC22 a few weeks back on our recent breakthrough with Chaos to fully ray-trace in real-time inside Unreal.

Hi guys, I want to set up a virtual production with Unreal Engine in my studio for some live shows through youtube. There will be a premade 3D studio scene and two or three guys talking to each other. I'll have multiple cameras with different focal lengths (for example a wide 24mm lens and two 85mm for tight close-ups). So when I select the camera with the 85mm lens I want also the virtual camera from unreal to switch to the same focal length. Here is my equipment list. 1) ursa mini pro 4.6K G2
2) pocket cinema camera 6k
3) studio camera 4k Pro
4) Atem Mini Extreme ISO
5) Design ATEM Production studio 4K
6) Design Web Presenter 4K
7) Design Video Assist 5" 12G HDR Can anyone please recommend what I need to purchase regarding sensors, plugins, additional software etc in order to make this work and be fully compatible with my equipment? I have some experience with the unreal engine on architectural presentations so I'm already familiar with the basics. I just need a good tutorial to get started. Can anyone help me?

[torpid fiber]

really cool!

[crystal merlin]

anyone working with ndisplay here? I,m trying to follow the quickstart guide but there are holes.. for instance. It's telling me to find the nDisplayListener.exe file.. I tried installed 4.27 and 5.0.. and it doesn't come with that file

[vapid void]

Hey UE Slackers! I have been battling with my Black Magic Decklink 8k Pro. I can get an input into the engine using the blackmagic media bundle but when I try to send our output (from our virtual camera) from the blackmagic card to an odyssey monitor It outputs green on the monitor. there is a feint visual of the environment and in the media capture pane it looks great! I cannot for the life of me get it to input and output simultaneously.

[shy bridge]

It's been renamed to SwitchboardListener.exe since 4.27. You might want to check something up-to-date with 4.27, as lots of nDisplay things changed in that version.

[stuck widget]

Hey everyone, did anyone else also noticed increased tracking latency for livelink when switching to 4.27/5.0 from using vrpn directly in 4.26?

Hi everyone. I need someone to help me with a specific shader (material) question. Is anyone willing and able to? Thanks!
In short points: I'm creating a "hunter" style game where you're a creature able to "have visions of his enemies once bitten". My effect is you push the ability button and for a brief few seconds you are able to see what your prey sees, but only to some extent. I'm doing this by having the prey camera capture to texture. The capture camera has edge-detect post-process and some actors turned off. I render target to a material applied to an image in the widget and show the image widget for the duration on the "hunter's" screen.
That part works nice, but I fail to achieve to remove the clear color (background) of the rendered and leave only actors seen by the capture capture camera with the FinalColor capture

[digital charm]

Hi, does anyone do any blueprint scripting with Take Recorder here? Having a hellish trying migrating 4.26 scripts to 4.27 right now.

[pure inlet]

How can I orient my camera "forward" to my tracker camera view?

I have become a tank controller

[steady swift]

I have a scene I need to render onto four monitors (each covering 90° of view, left, front, right, back), using a 2-gpu setup from a singular machine, is it better, performance-wise, to use a single node for all 4 screens or to separate them into different nodes, one for each screen?

[sour rapids]

Hi guys. I am looking for help with composting in UE.
I used a camera at 25fps to capture real footage and 3D environment in Unreal at 25fps. There is no camera movement.
However the final composite footage I have was lagging, the trees in the 3D environment move every frame but the real people footage only moves every 4 frames.
Since I want to use the composited footage from UE as the final product, is there a way to fix this lagging to make the footage frame by frame correct?
If its impossible to use UE for good composite, is there any other workflow for indie virtual production (keying and composite with aximmertry, or keying with obs, or other software)?
Thank a bunch for anyone's help with this issue.

Have you solved this yet? My vivetracker is doing the same thing..

[potent citrus]

So quick question here.. what exactly is the ndisplay root actor? I'm look at the NDC_Basic blueprint in the project and it says that the parent class is "ndisplayrootactor" but if I search the entire solution there isn't a class called that anywhere.

[zenith cove]

Does the LensCalibration plugin only work with Blackmagic or Aja media sources?

I'm trying to test it with my webcam but it's not appearing as a Media Source

[harsh flume]

On 4.27 and 5.0 I have

The field behind the dropdown allows for a stream URL, you can use the internal one for your webcam. That resource can be found when you create a media player and pull up the web can and it fills the resource bar.

[zenith cove]

Thanks, that worked, but it still does not appear for me in the LensCalibration plugin

Media Source is 'None' for me

Which is why I'm wondering if it only works with Aja or Blackmagic media sources

I would like to use an HDMI grabber which outputs its video to the computer as a webcam feed

[harsh flume]

I fired up 4.27 , virtual production template with starter content, I added a media profile (PleaseWork), a MediaPlayer with added texture as well as a lens fire. I put the stream url in the MediaProfile and then when I did a LensFile and calibration steps, it showed up

Is this the same Viewport Settings that it isn't showing up for you?

[lone wasp]

HI, it is possible to create texture2d from texture sample (float3) ?

[zenith cove]

Thanks, might be one of my settings or setup that's wonky, I'll check it out at the studio toorrow

[zenith cove]

Ok I get it now

Maybe it just needed a weekend's rest

[zenith cove]

OK I think the issue, I needed to have the feed playing in a Media Player before it could be picedj up

[pure inlet]

which one I should use, in-editor VP camera for led background stuff or a play mode camera?

play mode seems problematic that it always resets and vive tracker transforms seem very arbitray for me regardless where I set it in the world

and I cant figure out how to get non tanky controls for movement...

[zenith cove]

There have been implementations for UE4 to accomodate as much functionality in the editor

7 versions ago it used to be that you had to use play mode for lots of things

But indeed if you rely on in-game logic you still need to use Play Mode

[pure inlet]

okay that sounds good

yeah makes sense

I have an information overload

[zenith cove]

Are you using your Trackers headless? Without a headset

[pure inlet]

yeah

[zenith cove]

I get it, getting into this means you're diving into UE4, VR, Video Production...

How did you do it? I'm trying it myself right now too

[pure inlet]

simulation mode could be used to have animations play in the editor, right?

[zenith cove]

Yeah I think so

Hopefully the logic for VP will run then

[pure inlet]

I followed through Aiden Wilson's youtube videos on livelinkxr setups

[zenith cove]

I tried this tutorial for headless SteamVR https://vvvv.org/blog/using-htc-vive-trackers-without-headset

Ah thanks

[pure inlet]

he's got lots of good stuff but alot of it seems outdated already if you use livelinkxr plugin

I have serious problems doing the logic out of my head

and I keep messing up the blueprints hehe

[zenith cove]

keep on trying haha

is your headset connected?

[pure inlet]

yea it is

[zenith cove]

I'm tryign to figure out a pure Dongle+Vive Tracker workflow

Ahh yeah

[pure inlet]

but the headset hasnt been issue I think, it's basically in sleep mode

and I only get the vive tracker to the camera bp

[zenith cove]

Yeah sorry, I'm speaking about my headless setup woes. I've managed to do it with a headset connected

[pure inlet]

ahh

is it getting better for you

[zenith cove]

So what happens with you when you press play mode? The tracker is arbitrarily ste in the world?

[pure inlet]

yeah, or the orientation more so

and movement is hard, I managed to get a "manual" mouselook wasd movement in but it seems to f up the tracker camera movement

and there's always some weird jittering happeneing nonstop on the tracker

I think it picks ups building resonating or something

[zenith cove]

Jittering is normal behaviour on the tracker, it's got a lower refresh rate and fidelity than the controllers and headset

We've noticed it too

[pure inlet]

oh ok, is there any fix or way to smooth it out

[zenith cove]

Yeah you could implement a smoothing filter, I haven't done that yet so I'm not familiar with it'

[pure inlet]

man I'd be up for spending €€ on proper professional courses about this stuff but haven't found any that isnt like 3-5k

[obsidian relic]

Hello VP crew. Does anyone know how to stream an exr sequence, keeping the linear and high bit depth precision? Seems the media texture is srgb only, wont let me use nearest neighbour sampling, and seems to clamp -ve values to 0 :/

[pure inlet]

thanks ill check them out

[harsh flume]

Oops, you're right. Very curious if you find a solution.

[pure inlet]

can someone clarify to me the use of ndisplay setup, should I use ndisplay when I'm using a single big tv screen to act as the background for example product visualizations?

There's plenty of "how" to set stuff up but haven't come across any of the "why"

[dusty stag]

Hello everyone. Has anyone used the stype system and live link? When we connect live link to it, it drops fPS. If anyone has any ideas on how to stop that from happening I would be most appreciative!

[dusty stag]

It will run unreal without the gui in it. If you use multiuser, you can move things around while it is being projected on to the screen. Someone smarter than me can answer, but I also believe it helps reduce the load on Unreal so that your real-time playback works better.

[pure inlet]

thanks for your reply, so far I've used another viewport thats being piloted by a cinecamera on the "background" monitor but it would make sense to have more smoother performance if the ndisplay only renders whats in front of the virtual camera, if i understood correctly

[vagrant lily]

Hi all! I'm jumping here as almost a total novice, but have a question related to customizing virtual studios in Unreal:

Is it possible to script or automate custom studio designs so that someone could submit a logo/image file, and perhaps a primary and secondary color, and then have a studio created?

For context, I am working to support collegiate esports programs build out studio and asset packages to use for esports broadcasts. We have been using the Virtual Studio Kit (4.27.2) in the marketplace to adapt/build virtual studios, but we'd like to create the capacity for schools to simply enter their logos and colors, and be able to have a studio design generated off an open template.

If it is possible, I'm sure there's lots more to figure out from there, but just reaching out for some expertise/insight. Please and thanks! And if I'm poking around in the wrong channel, I am happy to be re-directed / please excuse my naiveté!

[onyx flume]

I think Epic just released a video on the Broadcast and Motion Graphics Sample. I haven't explored the project myself but seen some videos and it might be the answer, or lead you to the answer to what you're trying to do

[pure inlet]

hey just a dumb question, so the ndisplay renders actual game mode and not the same editor mode where it exists when ran thru switchboard?

[dusty stag]

I believe that is correct. But don't quote me.

[shy bridge]

I'm not sure what is meant by "game mode". nDisplay can be used with UnrealEditor.exe -game, which is what you get when running a standalone game from the editor; or with a packaged game (i.e., MyAwesomeGame.exe). But in both cases, it's the actuel game (i.e., after BeginPlay), and not the editor.

[pure inlet]

yes that's it exactly

[pure inlet]

I can't get the tracker to control the frustum on the ndisplay, works in the editor but not after I launch thru switchboard and join the mu_session

[tight rune]

Hello,
I tried to build a demo(including very very small size of cloth simulation) and played in oculus quest2(stand alone),
but cloth simulation did not work, actually it showed just a mesh without any cloth simulation.
However, Played Correctly in Unreal Editor's VR Mode.
So I was wondering if I did wrong with the unreal engine setting for oculus quest,
Are there some specific unreal settings that I should do for using cloth simulation? How shoud I do for it?
Thanks for advices, have a nice day

[zenith cove]

Try asking in #virtual-reality, there are some people who are working with the UE4+Oculus pipeline there

[tight rune]

Okay thanks

[heady bluff]

anyone know if theres a way to let an unreal application accept keyboard inputs when alt tabbed? (like how discord has push to talk buttons)

[pastel tiger]

Wait, does DX12 REALLY not support live video capture through media sources?

[pure inlet]

is VRPN used with multiple tracking devices?

[harsh flume]

Did you end up using OCIO or end up solving the problem?

[harsh flume]

I ran into a bug with UE5 dx12 along the same lines

https://issues.unrealengine.com/issue/UE-148398

[pastel tiger]

Yeah ill keep experimenting

[obsidian relic]

I'm now using spout from TouchDesigner instead! :/

[upper bramble]

I'm trying to get a tablet's rear webcam showing on a texture... in editor in a media player asset if I select the "Rear Integrated Camera" then select Tracks -> Video -> Track 0 (It defaults to Track 1 for some reason) then press Play it works. How do I replicate that in blueprint?

So far I've tried Open Url on the rear camera, bound an event on media opened and had that event run Select Track and then a Play on the media player, but this doesn't work... anyone know how to change the track? Am I doing it wrong?

Also is this the best channel for this question? or #cinematics ?

[upper bramble]

Got it, it needed a delay before the "Play"

[pure inlet]

when I pan my camera, the view in the ndisplay frustum does not "turn" with it, the frustum moves horizontally but the perspective stays the same... only whne I move with the camera I get the proper parallax...

[zenith cove]

So the rotation of the camera is not synched if I understand correctly?

[pure inlet]

if I parent the ndisplay under my camera actor I get the "proper" rotation

like if the camera exists in the world

instead of looking at a flat window

but I don't know if that's a right way to do it

I think the frustum view would pan realistically if the screen actually curved to the side or something

this just makes me want to go back and just pilot a camera in another viewport on my tv and call it a day

[solemn nova]

Hi Guys!
I’m having the following issue: I’m trying to set up a small studio with a projector and ndisplay.
nDisplay is working perfectly and the tracking is working perfectly when I am in the UE5 editor. I have made a CineCam actor and a CamActor which are connected, and I see perfect frustum tracking in the editor. As soon as I launch an ndisplay with switchboard there is no tracking and the frustum is not moving.
Waiting on any suggestions on how can I fit it. Thanks in advance!
Regards!

It may be a total noob question, but I'm really stuck in here 😄

[pure inlet]

do you have a live link controller component on your cinecam ?

[solemn nova]

Yes, i have one

It’s really strange, as it’s working in the editor, but not in ndisplay

Hi guys. I'm thinking about using aruco tags to set the floor for my production similar to this video. Does anyone has any tutorials or links on how to do this? The only thing I found on UE documents is used for LED walls and I cant apply that.
https://youtu.be/DQT0Qy856mA

[harsh flume]

I went down this path and watched that video many times. Have you tried to do a lens calibration and then using the aruco (or checkboard) to align to a wall?

https://docs.unrealengine.com/4.27/en-US/WorkingWithMedia/IntegratingMedia/InCameraVFX/CameraCalibrationForProduction/

Remeber they had an AJA and clean plate and then comped them later. If you just want a green screen a wall, there's Composure

Anyone know how to rotate the media plate in composure? I'm filming vertical on the greenscreen to max the pixels, but running into a wall trying to rotate the result in Unreal.

[quartz radish]

Hi, I've been trying to get render passes for testing. Most of passes looks fine but I can't get ObjectID (Cryptomatte) layers on my exr outs. Enabled and set the proper config on both 4.26 and 4.27 versions. Any suggestions what should I do to get? Btw, I'm using Djv instead of ps with exr-io.

[sour rapids]

No I haven't done any of that. I was gonna follow Greg Corson's video on lens calibration.
For the floor alignment I still haven't found a way to do that yet. I figure I should cuz my scene is gonna be quite similar to the video (walking up and down a corridor and it's a full body shot)

[zenith cove]

I've only done it with a checkerboard so far, but once you got the lens calibration working, then the camera alignment will work too

No special settings for that, just choose your Calibration Actor

Also make sure that the Aruco marker is visible in both the virtual and real camera feeds. Edit: Although I might be wrong on that one as this isn't the case with Philip Moss' videos

Also I found that the markers are at quite a sheer angle when aligning the floor and it can be difficult for UE4 to resolve the pattern. So the bigger your marker, the better

[slim rapids]

Hello,

I have a question regarding VR/OpenXR pluggin on Unreal.

I am working on an experience involving multiples VR controllers (I was requested to find a solution that goes up to 12 controllers).

I wanna know if unreal, does have VR controllers and trackers implementation that gives the possibility to get so much devices on the same time ?

Is there any existing available hardware to attain this objective, that unreal support ?

[broken lantern]

controller or tracker (eg vive)?

[slim rapids]

Both.

It is preferred to have only controllers, but i'm not sure that's possible.

[zenith cove]

You can wire the Vive Tracker up to have some basic controls with the pogo pins

Hey, this is not exactly full scale virtual prod, just a small ndisplay demo I'm setting up with multiple monitors
I have a 3090 to render dual screen, but whatever I do the FPS seems to be capped at 20? Any ideas? Is there config I missed?

Same with empty map with just plane, and an environment scene with 50M+ poly and dynamic lighting, doesn't make any sense to me

Both are easily running 100+ fps with PIE (so no ndisplay config, single monitor)
But when I launch via switchboard to 2-3 monitors, it's just 18-20 FPS fixed

Hello everyone, I am currently working on a virtual production project with real time composure and I am having issues with the foreground element of the composure. Whilst most of the actors can be excluded, I can’t find a way to exclude ExponentialHeightFog, Sunsky or VolumetricCloud, which results in having those three actors on top of the media plate.

Anyone know how to fix MRQ physics issue when using high Temporal Sample?

[sweet radish]

Hi everyone, Here is the virtual production reel for the company I work for called VirtualPro located in Guatemala. I would love to hear your comments on our work! https://youtu.be/L9GHnBiiSWE

[onyx flume]

Set the Motion Blur Amount to 1.0 (which doubles your motion blur length), then double the framerate of your sequence (24->48) which will halve the length of the motion blur, putting you back to the same motion blur, then you run a script in post that throws away every other frame.

I tried this workaround posted in the cinematics a few days ago and worked for me

[digital mirage]

[raven galleon]

Hi ☺️

Anyone knows composure media shadow and refrlection

[wise void]

I have 2 PC's connected via LAN and successfully communicating each other. 1st PC has vive tracker connected and I would like to run Editor here. 2nd PC is where I would like to run nDisplay but here I'm obviously not getting any tracking since tracker is connected to the 1st PC. So is it possible to send tracking data from 1st PC to 2nd one?

[zenith cove]

good question, there are multiple approaches you could do that

1. Write some code to forward the Vive Tracker data in the live link format
2. Use UE4's multiplayer/networking capabilities
3. What we did, we used OSC to broadcast transform data which we then received in the second PC

You can use other protocols other than OSC but I'm not familiar with it. I must say that OSC was pretty easy to implement and actually delivered pretty smooth usable results

[wise void]

Thank you. Can you elaborate on the OSC part? Sounds promising. Do you have any tutorial or articles?

[zenith cove]

We used the included UE OSC plugin: https://docs.unrealengine.com/4.27/en-US/WorkingWithAudio/OSC/

And we had a Blueprint that contained logic that would broadcast an actor's location and rotation if it was set as a sender

And if it was a receiver it'd receive and parse that OSC message as a location and rotation

Note that as far as I know, this only works during runtime so not during editor

So it might not be completely appropriate depending on the use case

I don't have any experience with nDisplay

[wise void]

Thank you 😊. I'll look into this.

[solemn nova]

Helo, so, does this means there is no way to make an 88 work at all?

[zenith cove]

Nope doesn't look like it is officially supported: https://docs.unrealengine.com/4.27/en-US/WorkingWithMedia/IntegratingMedia/ProVideoIO/AJAIOReference/

[zenith cove]

You could try but it's rather expensive piece of equipment

[solemn nova]

I already have it, so I better try! Thanks a lot!

anyone been having issues with UE5.0.2 live link animation from Maya? I can't get the Live Link Controller component to work, just comes up with None under the Animation Role. I can get it to work with an Animation Blueprint however...

Hi sender is oscclient and receiver is oscserver right?

[zenith cove]

Yep https://ccrma.stanford.edu/groups/osc/client-server.html

I've switched over to Sender/Receiver nomenclature but the UE4 implementation still uses that

[boreal scroll]

Anyone got tips for mocap software with livelink data? Been looking at Brekel and ipisoft with kinect 2 support, currently trying ipi trial, but it only has an ue4 plugin, compiling the plugin to ue5 doesn't seem to work right.

[zenith cove]

what's your budget

[boreal scroll]

Outside of a proper mocap suit :D

Looking for anything that can pass data from the kinect to unreal. Even diy projects is fine. Something along the lines of 200 euros or so

Free options are welcome too

[zenith cove]

I think the key thing here is getting the data into Unreal. It might be interesting to be able to implement that ourselves

[boreal scroll]

My thought exactly. I have "Mefamo" which handles raw face capture data and sends it straight to unreals Live link

[zenith cove]

Hah I just loaded up that github repository myself to check out how they format the LiveLink data

[boreal scroll]

Hehe

[zenith cove]

I've looked into it myself but Epic's documentation is a bit lacking there

[boreal scroll]

My ultimate goal is to have a camera rig, plonk it down infront of someone and just stream that person straight into unreal. An option to record the animation would be a plus

[zenith cove]

You could possibly do that with Google's Mediapipe https://google.github.io/mediapipe/

[boreal scroll]

Mefamo does facial tracking great. Just a question to get body going as well. Got a leap motion sensor to deal with fine hand tracking

[boreal scroll]

Been looking into this, could be a candidate

[zenith cove]

It's something that i've looked into previously but I never had the time for

[twilit osprey]

does anyone know how to fix the camera from Composures CG_element, it looks way different than my CineCameraActor, and my key stays transparent for some odd reason, all the videos i watched it just kinda works for them

[vale pond]

Hi all, for some reason, when using the Live Link VCAM app, it says Move iPhone to Start. When I do this, nothing happens. Video is coming through the link though. Any ideas?

[timber crater]

Left is ndisplay
Right is direct SDI
Does anyone know why there is such a big gap in the color space between these images?

[zenith cove]

@twilit osprey @timber crater For both of you guys, you'll have to look into colour profiles. I'm not exactly sure what settings or where those settings are, but sometimes some feeds are sent raw. Especially in the context of SDI

@twilit osprey For you in particular, have you got any post process volumes? Try adding them to your Composure list of actors to render

[onyx charm]

Hello, Does anyone know why I am not seeing the light source or the light beam but only the light once it hits an object? this is using the dmx fixtures built into UE

[copper warren]

Hi everyone
When using composure my CG layer render has more light than the original camera view (it's look like if it was unlit)
Have you some idea of what is wrong?
Thank you for your help!

in the world i have a post process volume, but ill try and add it to my Compousure list like you said and see if that works, and ill look into colour profiles as well thanks for your response!

[twilit osprey]

also i think im having a similar issue, look at Fragrag's response above

if i figure it out ill let you know as well

[thin iron]

@boreal scroll @zenith cove I'm trying to find some info on Live Link, I see you guys are doing some work with it, specifically for face capture ... see if any one of you can help me ... I'm trying to find a way (in Blueeprint) to get the status of the live link data ... I can access both the Subject and the Role, but I can't find any way to access the status ... I mean this as illustrated by the LL window ... the "light" that turns yellow once there's no valid data coming thru, and that is green when data is being received. Thanks in advance, and sorry for the tag 🙂

my objective is to switch the face to a neutral pose, or play an animation, if there's no valid data coming thru

[dusty stag]

I'm wondering if anyone has found a way to delete old sessions that have been created using nDisplay

[zenith cove]

No problems for the tag! Have you tried the Evaluate Live Link Frame node? https://docs.unrealengine.com/4.27/en-US/AnimatingObjects/SkeletalMeshAnimation/LiveLinkPlugin/LiveLinkBlueprintComponent/#evaluatelivelinkframe

[thin iron]

@zenith cove thank you for your answer 👍 I did look into that yesterday, but I don't see any good/easy way of determining the status ... maybe I'm missing something? I also thought of somehow getting the incoming values, and compare with last frame ... say, if last 50 frames all came exactly the same, assume it's not streaming anything? But I'd rather avoid this if I could

[thin iron]

fwiw, I managed to make it work 😅

I just picked a curve that, from my tests, is never ever absolutely still ... then compare it to last frame value, and do a counter ... if it comes equal n times, I consider it paused

so, thanks again @zenith cove for pushing me to reconsider that option 👍

now, on to find the proper way of switching between the live link and an animation 😅 ...

[safe temple]

hi there, i am currenly learning how to use ndisplay, i manage to get ndisplay to work, played around with the ndisplay configs and made one myself, but was wondering is it possible to get it work in a package build? basically if i was to send it to some who does not have ue4, can they just open the .exe and it will work?

[wooden flume]

That yellow vs green light for live link is just determined by how long it's been since we received new data from the source as there's no actual event from the device which tells us when it's actively tracking or not. I don't believe we have a blueprint function to do the check for you but you could easily make your own version of it in blueprint by getting the world time of your evaluated frame and checking if it's older than some threshold from the current time. If you're comfortable in C++ you could just wrap a call to ILiveLinkClient::IsSubjectValid and expose that in blueprint

For switching it in animations you'd just set a bool variable in the Update Animation part of your animbp and then in the AnimGraph you'd do a blend by bool using that variable that blends between the live link data and the animation you'd want

[thin iron]

thank you for taking the time and answering 👍 I'm not comfortable in C++, and this specific thing is a one man project, so I don't have access to any coders 😅 all in all, I think I did in spirit what you recommend 😄 but I did it in BP, as I described above. I also managed to switch between live link and animation, but again, in a much less elegant and clean way than what you describe 😄

but I will try to do it the way you suggest, by checking the world time

[twilit osprey]

did you ever figure it out

[safe temple]

Hi there, currently working with ndisplay and having a small issue, if anyone with some experience with it can help me i will greatly appreciate it 👍

[radiant marten]

Would thre be any interest in a plugin for using standard recording studio control surfaces (Ie Mackie MCU/HUI protocol) in UE5, in a similar sort of way to how lighting desks can be used? I need it for my own uses, so I'm gonna code it up, but if folks are interested when I'm done I can package it up as a plugin on the market.

My thinking is just to break it out so it can be used in nodes, Ie "Channel 5" object with pins for volume, pan, mute, solo etc, plus build an integration so the transport controls can drive a level sequencer.

Plus input pins to drive the flying faders on the better desks (Ie , I have a mackie MCU + extenders setup, when I use pro-tools the motorised faders will track the volume for each channel)

[timber crater]

Post process solved some issue, but now we have banding for some reason

[zenith cove]

I think your issue was actually separate from post process, as you were trying to match SDI with nDisplay right?

I think SDI transfers videos in an uncompressed format without any color formatting. I might be wrong though

Check out https://vpifg.com/guides/unreal-ocio/

Also LOL at this color pipeline, color spaces are never easy

[timber crater]

No I tried to match ndisplay exposure with SDI output

[timber crater]

@zenith cove
YUV is sent from da Vinci to the led processor, then from loop to BM decklink in ndisplay pc. We still having banding issues. It should be compressed

[zenith cove]

Yeah, it's possible I've sent you down the wrong path I'm sorry

dunno how to fix it either

[vast tinsel]

Hey sorry, I really don't know if this is the right place to ask, I'm brand new to Unreal, I come from the world of live theatre and sound/lighting design. I'm trying to work out if Unreal can do what I'm trying to do, before I sink a bunch of time into learning it. I'm trying to allow an artist to "draw" on a luminescent floor (light retaining material) with dmx fixtures. I'm hoping unreal can map the physical space, and translate xy coordinates into dmx values and control the fixtures. The real challenge is that I need to be able to record the artists inputs and replay them as a cue. I'm also hoping to let the artist "draw" using a touch screen that represents the physical floor. Does anyone know if Unreal capable of this, or how hard it would be to achieve? Sorry for the huge block of text.

[vast tinsel]

It seems like the way to do this is with a "follow actor" - the tricky part is being able to move the follow actor around freely and then somehow record and replay that

[zenith cove]

It is possible, I think I can see how, but it might not be the best tool for it? I think you might be able to create something like that in TouchDesigner no?

Ah but yes, of course you need something to allow the artist to communicate their movements to the DMX controller

[vast tinsel]

Touch designer is indeed the other solution that I'm looking into, but so far it honestly seems like Unreal would take less time to develop

Again the difficult part is the actual recording and being able to play it back as a cue, and that seems much trickier in touch designer, although I might be approaching it wrong

[minor hornet]

There are multiple methods to do that, each one with a drawback or advantage depending on your situation

[fallow basalt]

Hi guys,
Try to get things on remote control api for ue5 icvfx.
I want to make a light button that ones clicked can spawn/ create / copy/ duplicate a new light in unreal. Using the remote control api.
Is that possible or do I need to tap into python for that?

Trying to find a faster solution.

[somber prawn]

A noobie question:
The movie render queue outputs frames indivisually. How do you guys assemble the frames to create the final .mp4 or .mpeg video file?

And is it possible to produce the final video file from UE directly?

[zenith cove]

1. I like to use ffmpeg to compile the frames into a final video format. Others use Handbrake for that.
2. Yes, but I don't recommend it. It's been a while but UE had a limited selection of codecs last time I checked, also you run the risk of having a corrupted video file if UE4 crashes or hiccups during rendering, requiring you to restart the whole process again

[covert stream]

Hey guys,
My team is truggling to find a decent timecode generator/solutions to sync our LED walls & PCs
& camera & tracking system.
Thinking about getting a 5601MSC or an UltraSync ONE timecode generator + a VM-1021N VDA.
Any suggestions?

[pallid heath]

you can call ffmpeg from MRQ using the Command Line Encoder. you'll need to set it up in project settings as well

[pallid heath]

I prefer to use TouchOSC. easy enough to create BP nodes to respond to it

[crimson arrow]

Hey guys, do you know if there's any way to record a variable through the take recorder.
I see that I can record properties of the component of my source actor but can't find a way to record a variable of a BP added as a source actor.

Here I can record the visibility or transform of some components but I can't find a way to get a specific variable from the pawn.

[echo wigeon]

Does anyone know how to render a video?

[visual basin]

I think there is a setting in the livelink connection somewhere that allows you to switch from world coordinates to local or something.
It's probably using world location which matches your tracking origin to the world 0,0,0

Is anyone else suddenly having trouble with launching the switchboard? After a pc restart it just won't launch anymore... Only shows a cmd window for a few frames and quits out. Really stumped on wtf happened here.

[pure hollow]

Hi, Who has knowlage on NDisplay?

So I am trying to do something simple enough

I have a game I am trying to help my friend with, its a game where you drive around in a bus, taking people places, Anyways, He wants it to be setup like this:
If you run the project, on 1 monitor you look to the front of the bus

If you have to it does that and on the second monitor, you see to the left of the bus or to the right (Depending on what you select as an option)

And if you have 3 monitors then you see forward left and right

I have started setting up the NDisplay config, Is it a good idea to use NDisplay for this?

[pure hollow]

Okay I have managed to run it

I have another question though

Can I streamline the launch process so It automatically launches a config?

If you imagine it would be a bit weird to have to launch through switchboard everytime, if its a game?

Hmm, the switchboard button is gone in the editor now

[shy bridge]

For a game, don't use nDisplay. Unreal probably supports multiple monitors natively, without having to use nDisplay.

[sour rapids]

I have the same issue, but things return to normal color in play mode so i suggest you try hitting Alt+P.... What I need now is fixing the issue with the sun flare, the camera has a lot of flare but the playmode has none. I tried entering playmode without composure and that fixed it, so the issue definitely lies in the comp CG layer

for reference this is the color I got in preview composure, it lose a lot of light

[copper finch]

Hi there, does anyone have any idea how to setup an htc vive tracking system with just a tracker, meaning thst I can set the center point with the vive tracker instead of the headset?

[valid geyser]

Im getting our led volume working with n display but im thinking there must be a way to calibrate with just the tracker no?

[zenith cove]

haha, haha, haha, no

it's one of my main gripes

[zenith cove]

https://www.youtube.com/watch?v=DQT0Qy856mA Illustrates a method of working with the Vive trackers without headset

I asked them how they calibrated the play area and they replied:

When we first started we would put a 1mx1mx1m cube into the virtual world, and then line it up with a 1mx1m L-shaped piece of wood in the real world. They would only match exactly when the two cameras were the same height above the floor. Once they matched, you had calibrated the zone. The Aruco markers just do this for us now, because the software works out the height and distance (and angle) that the virtual camera should be at, to give the same perspective view of the real and virtual Aruco tags.

[valid geyser]

Hmm

I tried using openvr advanced settings

And then used a null driver and then turned off required hmd

And them hit recenter by having the vive puck in the dead center of where inwanted it

That seemed to work

I has a massive hallelujah when i figured it out

Now i jusy have to go into our studio to test it on the wall

[valid geyser]

Gotcha, but how do they do the aruco marker calibration in unreal?

[zenith cove]

The built-in Lens Calibration plugin from Epic

[zenith cove]

it's bit of a beast to figure out to be honest

[grand lance]

Hello Guys! I'm developing a small studio for Indie virtual production. A led wall is too expensive for me right now so I'm thinking in buy 2 laser projectors Consumer Optoma to blend in one screen, 1 camera Panasonic bgh1 (sdi and genlock ports) and BM sync generator.

I have HTC trackers for tracking ,one RTX 3090 for the output and BM decklink 8k pro sdi input and genlock

I read a lot about the Genlock for VP so my concerns is the projectors and the Video card don't have genlock

I would really appreciate your help with this as I don't want to spend so much money and have it not work for me.

[valid geyser]

Yea, im doing research and development and its been brutal. Especially because 5.0 still has most of the vp stuff in beta so most of it is buggy and incomplete

[valid geyser]

You need a genlock card. Im not sure exactly how it works, but the card syncs the video output of the gpu and sends a genlock signal to the displays. Since you cant genlock a projector you need to set the output framerate of the projector to a common multiple of the input of the camera (such as 23.98 or 47.95 or 24 or 48) this will make it so you dont have rolling shutter

This wont be genlocked but it will be LIKE genlock.

As for true genlock. Only rtx quadro cards have a true genlock generator to sync to an external card which then goes to a camera and monitor/display

For our led walls, we just set the framerate and display refresh to the same thing and then have it be a multiple of the camera framerate.

[grand lance]

I am seeing that the quadro 6000 and 8000 used are more accessible on ebay. I'm going to think about it . Thank you @valid geyser for this information it is very helpful for me. When I have the setup ready I will share my experience

[valid geyser]

Keep in touch. Interested to see how it goes

Also

[grand lance]

Sure !

[valid geyser]

You can cheat genlock imo. From what ive learned

You can fake it

Its cheaper to keep then out of sync but in the same hz ratio than to go@crazy with a gou

[lyric kelp]

Hey, guys! I'm newer to this stuff and trying to understand some basics. Generally speaking, does "virtual production" only include when you're doing Mandelorian-style live backgrounds, or would tracked chroma key stuff be considered virtual production as well?

(I'm working on a sci-fi web series that needs some help on this front, but we're leaning more toward the green screen side and I'm not sure what terms to use to explain what we're looking for when trying to find someone.)

[halcyon hill]

Hello Everyone. Can anyone point me in the right direction? I am looking to make an Unreal Scene that will be used in Livestreams**. I want to find a way to align my UE5 Camera with my IRL Camera (Logitech c920). I wont be using Unreal When I am live, just the exported renders of the scene (Loops,transitions, ect). Does anyone know how to do this**?

The camera will be Stationary of course (because I am pre Rendering the background footage)

[zenith cove]

I think the most simple and quickest way to do that is just to wing it. 😛 You could go into the rabbit hole of tracking and alignment but in the end, I think eyeballing it will get really decent results already

[queen beacon]

Alrighty, I'm using UE5 and trying to set up switchboard but all the tutorials use UE4, even the official documentation... To launch switchboard and the switchboard listener, I need to click on some button in the toolbar but the UE5 toolbar is missing these launch buttons.. Any idea where I can find them?

[halcyon hill]

@queen beacon sounds like you need to enable the "Switchboard" plugin. I'm just guessing because I ran into the same exact issue with a plugin I'm using. Once I enabled my plugin, the button for my plugin options are now at the top of the screen.

@zenith cove I'm a perfectionist lol. I suppose I will try both methods.

[modest frost]

hi there, anyone had issues with livelink offsetting a camera when using a VR HMD as a link source? I am trying to pilot a camera using the HMD, the take recorder tracks all movements, but starts from a different position, i.e. not the one I am seeing in the HMD so the whole sequence is off set. If I try the same thing in the OpenXR template level I have no issues, but I can not figure it out.

[copper finch]

if you're using steamvr, take a look at the 'in-hand' orientation. this can affect incoming live link data iirc

[modest frost]

Thanks! I will check that out; the odd thing is that if I turn on the debug visualization (the one in the OpenXR blueprint), the position shown is correct, but as soon as I start the game it seems that the player pawn and the camera get two different origin points.

"Composure is an amazing tool, and highly valuable for bypassing Anti-Aliasing of your input video feeds, but it uses Scene Capture 2D to create a camera output and so lacks the amazing visual capabilties of Unreal's Cinecam."

Does this explain the questions we occasionally get in here asking why the visual result you get from Composure can be very different?

I'm new to virtual production and trying to setup my nodal offset. The problem is I have only one tracker. Is there any other way to calibrate the nodal offset with just one tracker?

[digital charm]

Does anyone work with Take Recorder here?

[lofty zephyr]

is there any pluging or blueprinting routing for live or rendered rotoscoping (live feed camera), thanks a lot

Does anyone know what the best virtual production software is for cinema and not broadcast purposes?

We're looking at brainstorm and pixotope but was still wondering if there's something we're overlooking

Anyone worked with Pixel Mapping and knows how to controll the Play DMX without having to press it manualy in the Editor? like in a blueprint. I couldnt find a fitting node for that

[pulsar flame]

why not just use Unreal?

Looking for some help. I’m trying to render a sequence that includes a physics sim with destructible meshes. But for some reason I’ve ran into an issue where the video rendered doesn’t match the what plays in the editor regarding the simulation. Some thing is also happening where it doesn’t require me to enable the physics of the destructible mesh in the sequencer timeline to render the video with the sim. I’m lost for answers if someone could point me in the right direction.

Hello, I have a big problem with unreal engine 5 and opti track
Basically I linked skeletal mesh from live feed and from recording through Motive using Live Link plugin.
An animation blueprint was made and the only things connected are: Default Slot to Live Link Pose to Output Pose as a result

The problem begins when I move a camera in a Playmode. Unreal instantly crushes, leaving me with Index Out Of Bound upside_down
The same thing happens in a Preview window.

Any idea why?

Interesting, what skeleton are you using?

What if you try the set-up as described in Motive's documentation: https://v22.wiki.optitrack.com/index.php?title=Unreal_Engine:_Skeleton_Streaming

oh oops, I linked to some old documetation sorry hold on

I can't find an equivalent documentation page for Motive 3.0 aside this: https://v30.wiki.optitrack.com/index.php?title=OptiTrack_Unreal_Engine_Plugin

We tried this but unfortunately we got the warning "the node OptiTrack Skeleton" is from Editor Only module, but is placed in runtime blueprint! K2 Nodes should only be defined in Developer or UncoockedOnly module" when we tried to sync a OptiTrack Skeleton
