This addon aims to help you to create mocap data (animation) using a single video as input.
You can find the official github code where this addon was based on the link: https://github.com/shubham-goel/4D-Humans
Attached you can find the addon
Funny note: The first version was 0.04 because while recording the tutorial, I had to stop a couple of times to fix several bugs.
PS.: found another bug and replaced with the 0.05 version
UPDATE: If you are having problems, is possible that the script is not able to download the cache files form the internet,
In that case, you can download the pack of cache files from the addon dependency on gumroad , here is the link with discount: https://carlosedubarreto.gumroad.com/l/dependency/2jhtxqo
You will need to download it on this folder: "%HOMEPATH%\.cache"
You need to put this text on the windows explorer
Example:

Press enter and it will convert to the user path of the one you are logged in (in my case my path is usuario\carlo, as you can see on the print below

if the folder ".cache" dont exist, please create it and paste the ".cache.rar" that you've downloaded
Extract the contects of the ".cache.rar" that you've downloaded. and it will look limilar to this

Try to run CEB 4d Humans again and probably it will work.
