Would that be possible with just one camera?

Was just trying out this add on to do some hand tracking and its very impressive, the problem ive run into is that the left and right hands are swapped. So my left hand ends up on the characters right hand, this causes some serious glitches as I have rotation limits in place, and the hand is trying to rotate in the wrong direction. Any idea how to fix this?

Thanks,
Steven

when install dependencies, it going to wrong.
Command '['D:\Software\blender-3.0\3.0\python\bin\python.EXE', '-m', 'pip', 'install', 'mediapipe', '--user']' returned non-zero exit status 2.

I find it unsettling to have to run the app with admin privileges. There should be, instead, a workflow to enable the permissions required piecemeal. "Add yourself to this group, etc." Or maybe install the packages locally? Or somewhere where the normal users have access?

As a side-note, I run my app on Linux as a normal user and it works well, webcam and all.

got this error when I press "install dependencies" in blender preferences

Hi! After I press the Start Detection button, there's an error command,

The Blender Snap package is "unconfined," so I don't believe it is an issue with Snap sandboxing, but I could be mistaken. Is this perhaps a Blender 3 issue?

Soo yeah, ive done every step correctly, opened up blender with privileges and tried to install the dependencies, but whenever i tried to, it always ended up bugging and leaving this message for me

Command '['C:\Program Files\Blender Foundation\Blender 2.91\2.91\python\bin\python.EXE', '-m', 'pip', 'install', 'mediapipe', '--user']' returned non-zero exit status 1.

I'm not sure whats happening, i tried to restart my pc, update python, run legacy versions, but none of them worked. What could be happening?

Hello!

When applying captured hand movements, the hands never seem to be angled properly and always turning in unnatural ways. Is there any position I need to put my hand in so they stay straight forward instead of straight up or to the side?
Example:

click the install dependencies, but also cant to work, could you help me, thanks.

iPhones have lidar and can be used as webcams.

This technology could potentially help with tracking.

Hey!

Trying to get this puppy running on MacOs on a Macbookpro M1 Max unit.

So, first thing that comes up is getting dependencies running. Mediapipe isn't officially packaged for arm64 based macs. However an unofficial package exists called "mediapipe-silicon". AFAIK it should be possible to fix that on a mac by editing BlendArMocap-release/src/cgt_blender/utils/install_dependencies.py

And change the lines after import bpy.app to

Dependency = namedtuple("Dependency", ["module", "package", "name"])
dependencies = (Dependency(module="mediapipe", package="mediapipe-silicon", name=None),
                Dependency(module="opencv-python", package=None, name="cv2"))

It should install after this. I think.

if it doesn't a command something like

/Applications/Blender.app/Contents/Resources/3.1/python/bin/pip3 install opencv-python
/Applications/Blender.app/Contents/Resources/3.1/python/bin/pip3 install mediapipe-silicon

ought do the job.

Now. What I've found from here is that Blender launched from the desktop by mashing the Blender.app (or launching it from spotlight) will crash out completely when running "start detection". My guess is its colliding with sandboxing and permissions for some reason.

HOWEVER

Running it from the command line seemed to work fine (Though I did do a xattr -d -r somethingorother.sandbox type thingo to remvoe sandboxing, not sure if necessary), however it is fairly buggy. Im not sure if its stuff others are seeing, if its something fixed in the github already, or its a side effect of my particular arangement of things. Its erratic though. Often if it fails, trying again works.

There are bugs about not enough, or too many values, unplugging from the observer (I wasnt actually aware this abstract base class stuff was actually in python, figured that was more a Java curse lol.

If you wish I can provide error dumps.

WITH ALL THAT SAID. Good work my dude! This is actually really good stuff. Its already more featureful than some commercial mocap things. Sure its buggy, but glory does come overnight, it takes work. And I really applaud what your doing. This true open-source integrated hands and face and body mocap from a single camera, built into blender could turn out a real game changer for this industry.

Some nice-to-haves:
Multi camera! Dont know if OpenCV and your own algorithms could be coerced to do this, but 3-4 $30 webcams + an aligment method would push this over the edge into a truly production useful solution.
Un-enumerate the camera drop down so we can work out what option refers to what camera (I have 5 cameras in my studio)

Havent checked out the transfer stuff yet. Will report back if its borked.

# Python backtrace

Hi,
this is a great project, thank you for your hard work!

Version "BlendArMocap-beta-120.zip" (main branch) worked, but the dev branch downloaded on the 27th of March had the issue that the webcam window would not close anymore by pressing ESC and reopened immediately if closed by clicking on the X on the window header or using Alt-F4, so it was unusable. Also going back to the older version did not help, the issue persisted. Each version was removed before installing the new one.

Now with version 1.4.0 from main branch, the webcam window won't even open after clicking "start detection".

Blender 3.1.0, platform: manjaro stable

I want to subscribe to github updates on new releases to be alerted when a new version is released.

The text on the buttons here seems to not be displaying properly, I am using arch linux with the GNOME desktop environment.

Blender 3.1 Phyton 3.10.2 No Mediapipe found

make use of pose lib instead of constraint to allow easier output manipulation

Install went well, I allready had the dependencies, I don't have a webcam so I used Splitcam to feed a video instead.
"Start Detection" works like a charm, but when I close the window showing mediapipe at work, it automatically reopen.
No more keypoints seems to be written, but I have to save and reopen my blender file to get rid of the video popup.

Windows 10
Blender 3.0.1

giving the possibility to use custom rigs

First of all, thanks for developing such great things,
I am playing around with the ArMocap and the Blendtrack 2.0 since a few days
and I couldn't really archive my first success with it but maybe reporting what
I get to see on my end might hopefully help you improving it.
I love the stuff you do so far and I hope it will get even better.

As written above my issue is to transfer the captured movement onto generated into a Rigify-Rig
(made from a a standard blender human rig)
I'm using a mac, running blender 3.0.0 (also tried other versions, elder and younger) but I always
get the same error (below) leading to no movement in the rig.

This is the error message, hope you have an Idea to solve this:

Wonderful project! What a gem! Congrats @cgtinker

But this wonderful plugin (1.4.1 and 1.5dev) in Blender 3.1.2 on Ubuntu 21.10 doesn't work as is.
In today's version (1.5.0dev); on hand detection with a human full metarig:

All is installed using Blender deb package:

I've run on win 11 steam version via admin elevation- unable to install dependencies. It is not clickable.
v3.1

idk how to close cam

I'm unable to Enable the Addon :

I get the following error message when trying to get the add on to install dependencies. I have mediapipe etc already installed. Per the instructions, I opened blender in admin mode through sudo command in terminal. Watching the progress there, it looked like finding/installing modules wasn't actually the issue, the error seems to come afterwards?

I'd love to get this add on working!!

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:

1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates

Great works! Is this also workable to rigs that doesn't have IK drivers? E.g. If I create a generic character in blender, can I still use this to rotate the bones?
Thanks.

Hello everyone!

I have tried the BlendArMocap plugin, it works perfectly.

Is it possible to run all three mocaps (hands, face and pose) at the same time?

I hope your help
LuisFer

In pose capture, when I balance arms left and right, the whole body is seen as rotating around Y axis.
Even after zeroing hip center rotation, hip left and right Z locations, feet rotate around Y axis.
Here I had my 2 feet on the ground, only my hands are on the left:

selected are 3 hips curves (center Y rotation, Z locations for the 2 others) and you can see they are zero.
I don't know mediapipe and in the capture, I was not rotating on screen.

Is there a way to set root to feet for us non-dancers? 😄

Can we use recorded video instead of live camera?

Hi
I tried to "Start Transfer" but it did not work and I got these errors:

Before receiving this errors message, I did face, hands and body capture with "Start Detection" then Add rigify Human(meta-rig) and Select the on of cgt_FACE , HANDS and POSE from "Animation Transfer" panel and Select Armature "metarig" then press "Start Transfer" button,
blender 3
rigify 0.6.4

Here's error note

Who knows what happend, The same result with my VPN on/off .

anyone meet this error message? using the master zip file, but can't install.

Can we remove all drivers?

Hello,

Ive started the Blender with admin privilege's but get this error ?

Installing collected packages: opencv-python
ERROR: Could not install packages due to an OSError: [WinError 5] Access is denied: 'D:\Blender\3.1\python\Lib\site-packages\cv2\cv2.pyd'
Consider using the --user option or check the permissions.

Hello is it possible to use pre-recorded videos of the desired animation instead of creating live videos with a webcam?
What is the ideal way to change the video setting for this application?

Thank you!

This is the error I am getting, Running it as administrator. it continues to say "Module not found" and "unknown argument, loading as file: -m" which seems to be where it fails.
