RTX Face Tracking in TouchDesigner - Tutotrial

[@andrewcharles3362]

Your tutorials are really helpful. I am having trouble with getting any values from my bounding box confidence though for a project

[@TheInteractiveImmersiveHQ]

Cheers! :) Re: bounding box confidence, I would try the recommendations mentioned here: forum.derivative.ca/t/face-track-chop-bounding-box-confidence/533506

Thank you for the great video! I learned today that Windows 10 allows me to type "cmd" in the address bar of the folder I'm in, and it will run the CMD prompt from that folder. Super efficient, hope it helps someone.

Our pleasure, thanks for watching!

[@TheInteractiveImmersiveHQ]

Also, great tip! Super useful way to optimize the workflow in Windows

[@atltvhead2840]

Great video and instructions! Showing how to instance with it was really helpful for me!

[@TheInteractiveImmersiveHQ]

I'm glad to hear! In the next few videos, we'll be diving into more content creation so I'm sure there will be other tricks you'll enjoy :)

[@atltvhead2840]

Awesome! Looking forward to it!

[@sdhruv95]

There's also non rtx facetracking with mediapipe quite handy

[@TheInteractiveImmersiveHQ]

That's true, I've heard good things. I'll give it a try and see if we can make a short video about it as well.

[@atltvhead2840]

I've always run mediapipe outside of TD and send the data in over osc. Fps kinda tanks when running it in TD. That being said I was running the Holistic model, which is a combo of all others so it might be a little much.

You do not need the mesh or to do the whole complicated part at the beginning! The Landmark points are separate and you can just switch it on in the Face Track CHOP.

[@TheInteractiveImmersiveHQ]

Nice find! Seems like you can get the landmarks without needing the generate the mesh file at the beginning. There are other features that might be locked behind the mesh file, but that's great to know that you could easily get those landmarks without them :)

[@ruthjarmanandjoegerhardt4853]

Yes, the mesh is for the face Track SOP so it now seams strange that the mesh is loaded into the CHOP and not the SOP! @@TheInteractiveImmersiveHQ

[@ruthjarmanandjoegerhardt4853]

Also it seams that we are both having an issue where the Face Track Landmarks are squashed horizontally making them not fitting our face when mapping them back over the Video Input.

[@7n454]

Hello, thank you for your tutorial. When I complete the "command prompt" step and enter TD, I encounter a problem. After I complete the facetrack setting, I do not detect face data, and "failed to load feature: the file could not be found" is displayed. I see that there are 8 files in the fasemesh of your tutorial, and I only have 7. I don't have the "face_model0" file. I can only put the "output face_model0" file into the "mesh file". I don't know which step I missed. Can you give me some suggestions? thank you

[@TheInteractiveImmersiveHQ]

Can you copy and paste the command you put into command line here? My best suggestion would be to start the process from the beginning and pay close attention to what files you're downloading, where you're saving them, and running the commands exactly like I am.

[@AngusMacMinn]

Hi! Weird question, but when I click on any of the last 3 files in the Github, there is no button to download them... The first 2 did however, so I'm unsure if missing something or what. Actually the edge topology one has a download button but when clicked it just opens a bunch of code. Anyway if anyone knows what I'm doing wrong let me know!

[@TheInteractiveImmersiveHQ]

On some files on Github it doesn't show the download link, what you can do is click on the "Raw" button to see the full contents, then you can copy and paste it into a text editor and save it to the appropriate name and file extension. Alternatively you should also be able to right click on the "Raw" button and select "Save link as..." and it'll function similar to directly downloading it.

[@thomasantoinepenanguer2629]

Hi, thanks for your tutorial. i've got a command issue : Unknow format for contours.

[@TheInteractiveImmersiveHQ]

First, just want to check that you have a 20xx or 30xx series Nvidia RTX card - any cards not in the RTX 20xx series or 30xx series will not work (this includes 40xx series cards). Second, double check that you've downloaded all the correct files and followed the instructions from the wiki article: docs.derivative.ca/Face_Track_CHOP

[@thomasantoinepenanguer2629]

Ok thank you for your answer, so it’s a série card issue on my side.

[@JordanEspionage]

I'm getting an incompatibility error when trying to run the exe in command prompt -- anyone else experiencing this?

[@TheInteractiveImmersiveHQ]

Hi Jordan, what hardware are you running on? Can you copy and paste the command you're running in command prompt as well as the error it's giving you?

[@mixarstudios]

Hi Jordan, I had the same problem, I went back an redownloaded the files and reran the command and it worked. Maybe a corrupted file or something.

[@HAINILOVE]

Thanks for the tutorial, how can I achieve the same effect with Kinect?

[@TheInteractiveImmersiveHQ]

Our pleasure! You can use a Select CHOP to isolate the face-related channels that the Kinect provides and then follow a similar technique to the video to generate an instancing effect. The number of channels is going to be different than what RTX Face Tracking provides, so the final outcome is going to look different than what you see here.

[@李嘉意]

sorry， I am not getting the face_model0.nvf file. I couldn't move further.

[@TheInteractiveImmersiveHQ]

Have you followed the steps described at docs.derivative.ca/Face_Track_CHOP to generate the nvf file? If so, have you placed the conversion tool in the same folder as the Surrey Face Model files? Are you receiving any error messages?

hi got this error!!im running win10 home 64bit!! This version of C:\facetracking\ConvertSurreyFaceModel.exe is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher.

[@TheInteractiveImmersiveHQ]

Hmm that's interesting. I haven't seen that one before. Could you try downloading Nvidia Broadcast app and seeing if that works on your system or if it also gives you an error? That'll help us track down the issue

[@XanthanGumOfficial]

I installed Nvidia Broadcast and that works just fine.

[@JorgeAlbertoEstradaTorrecilla]

When I press enter after pasting the code., nothing happens, What am I doing wrong?

[@TheInteractiveImmersiveHQ]

One thing to double check is that you've pointed the command prompt to the right directory before running the code (see 6:30 in the video). Also, if you're using the code from the video, make sure that you've got all of the required files in the same folder. If they're located elsewhere, you'll have to specify their location in the code you enter in the command prompt. Hope that helps!

[@sarahbeauclerk4708]

Hello - thank you for all the amazing videos which I've been following for a while now, and I am planning to subscribe to the full service - for some reason my render will not display the face-tracked image... one reason might be that I was originally trying to get the process to work within an existing scene that already had another render and camera (and it seemed to be trying to pull the information from there)... though now I can't get it to work in its own scene, or even in another file entirely. If there is anything you can suggest I'd be very grateful.

[@TheInteractiveImmersiveHQ]

Hi Sarah, sorry about the delay responding! Can you give me a bit more information about what you're seeing when trying to run this in a new project? Do you see data moving in the CHOPs? Can you tell me about what kind of system you're on (mac/PC) and which GPU you have?

doesn't Nvidia GTX graphic support to this? what is the solution ?

[@TheInteractiveImmersiveHQ]

Unfortunately, the Face Track CHOP requires a 20 series or higher Nvidia GPU, so this particular effect is limited to RTX cards only. If you're still looking for face tracking options that you can use with the GTX card, you might look for a used Kinect 2 and PC adapter. That might be a cheaper option than upgrading to a newer graphics card. Hope that helps!

[@КатяКурмышкина-ш6н]

Unfortunately it's not :( The SDK the Face Track CHOP uses is only supported by Windows and an Nvidia RTX graphics card
