Come Join LIVE UE5 Q&A, every Monday and Wednesday on twitch.tv/rikku_vr/ If your cam is just flashing for a second and then turning off, you need to redownload the AR SDK From Nvidia Broadcast's website www.nvidia.com/de-de/geforce/broadcasting/broadcast-sdk/resources/ (thank you CapNamNam on Reddit 🙏)

I got it working, however there are occasional single-frame jitters of the affected bone locations. These happen at any frame rate and last for a single frame. They also occur in shipping builds. The blend shapes work just fine. You wouldn't happen to know what is causing this, would you? The skeleton I'm using is the UE5 default one I extracted from Manny.

@RikkuVR 10 ай бұрын

hmmm no idea what might cause that...maybe lots of USB devices so some packets get lost?

@JoshTrevisiol 10 ай бұрын

I did think about that, but the avatar image was coming in clean, just the bone transforms were being fidgety. Maybe it was my rotation orders or local rotation axes.@@RikkuVR Anyhow, I just wound up making my own IK solve instead so it's fine in the end. Thanks for the video that got me started! Excited to try out being a 3D Tuber. 😁

The tracking only shows in anim blueprint. But nowhere else? And ... How do u record the face tracking in sequence? Advice?

@RikkuVR Ай бұрын

did you apply the animBP in the actor itself in the scene? You could record the face with take recorder and put that into sequencer

thank you! hmmm you would need to create a menu for the player to select their webcam device probably, cause it cant auto recognize but technically that should work yeah

Hey, tell me you have an answer for this. I want to buy a camera with infrared to use for tracking, like they do with iPhones, but every forum says it's not possible. Do you know if there's any way to do this?"

When using with Unreal Engine 5 Metahuman, only the head tilt data is being interpreted. Is there a mismatch in bone names perhaps, if so is there a way to correct this?

@RikkuVR 5 ай бұрын

it is probably because the blendshapes on the metahuman are named not exactly after ARKit conventions / a lot of facial animations are driven by bones as well iirc so you could look more into that...theres a node in the animBP "anim node fix curves" you can use to rename / reroute those blendshapes

Hey Rikku! For some reason when I open the application it flashes webcam on for a second and the app shuts down. Any pointers? Thanks so much !!

@RikkuVR Жыл бұрын

hmm could be a driver issue? Did the Nvidia broadcast drivers install properly? I had some issues with them and needed to reinstall a second time

@RikkuVR Жыл бұрын

Heya its me again :) someone on reddit found the solution for it, you need to get the ARKit SDK from Nvidia Broadcast as well, apparently I had it on my PC for a bit now cause I was testing different things before lol

@martinmenso6671 6 ай бұрын

Would it be possible to get the tracked webcam head location from the Evaluate LiveLink node (or any other way to get the data) to track the head location 2d to world location in Unreal Engine. What I am trying to achieve is to have a virtual avatar to always look towards the person on the webcam.

thats a good question, I havent looked into what data you can manually pull out of the setup

@@RikkuVR I tried iFacialmocap. Everything is working except the mouth and the blinking. Idk what I'm doing wrong. There's literally no tutorial anywhere besides yours that constantly keeps popping out. Hoping it wasn't because it's UE 5.3 or else I may have to downgrade.

@@RikkuVR It took me several days and a lot of youtube videos so at least lemme share it or maybe I could make my own tutorial. You can skip below but I have to explain what I'm using this for. Okay so I'm using Daz Studio Characters on Unreal Engine. I have use the DaztoUnreal to export Genesis 8.1 character model to Unreal. I connected iFacialMocap to the source and the head and eyeball movement is working but the entire arkit morphs aren't working at all. So I dived in to all tutorials you can find on youtube to figure out what's wrong and it's making me give up on unreal itself. Then I realized something and here's the skip. SKIP The Morph names on Unreal are named differently. I think it's case sensitive. Even if it's the same name, if it's upper case on unreal, the default names from iFacialMocap won't work. Also it has space so you have to include that. I tried renaming all 52arkit names on ifacialmocap and it's now working. My God, I feel like I wasted 3days of my life. Anyways, I thought I share that. I know you don't do Daz Studio stuffs but just in case you decided to do a CodeMiko vtuber stuff, this is godsend. Anyways, thanks for your initial aid.
