// Mixamo Animation downloadeer
// The following script make use of mixamo2 API to download all anims for a single character that you choose.
// The animations are saved with descriptive long names instead of the short ones used by default by mixamo UI.
//
// This script has been written by gnuton@gnuton.org and the author is not responsible of its usage
//
// How to use this script
// 1. Browse mixamo.com
// 2. Log in
// 3. Open JS console (F12 on chrome)
// 4. Download an animation and get the character ID from the Network tab
// 5. Then past the character id in the "character" variable at beginning of this script
// 6. Copy and paste the full script in the mixamo.com javascript console
// 7. The script will open a new blank page.. you will start to see animations downloading
// 8. keep the blank page opened and keep on pressing "Allow multiple downlaods"
// NOTE. This doesn't really work for me, but it was supposed too
// Chrome will ask you all the time to allow multiple downloads
// You can disable this as follow:
// chrome://settings/ > Advanced > Content > Automatic downloads > uncheck "Do not allow any site to download multiple file automatically"
// CHANGE THIS VAR TO DOWNLOAD ANIMATIONS FOR A DIFFERENT CHARACTER
// const character = 'aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee'
const character = '2b3be6e3-a811-4a3d-a44e-fa2fa827bc93'

Hey quick question how can i change 158 to only download In Place animations?
Thank you for your help :)

hey, I haven't dealt at all with exporting in place animations from mixamo.

possibly between lines 87 and 88 you would check the value of in place in _gms_hash and only proceed if it is an in-place animation.

Otherwise, on line 158, I think you would need to edit the value of in place in gms_hash, setting it to true.

Might be easiest to write a script on blender to get rid of root motion data?

First of all thank you for your quick response. I randomly tried changing 158 to make inplace true but javascript isnt really my strong suit so it didnt really work. There are ways to deactivate root motion in blender however there isnt any script for it...
How would you edit gms_hash to enable inplace? Thank you again for your time :)

Honestly not sure, this was my first time using Javascript, so my js skills aren't too great either.

Hopefully this points you in the right direction: https://stackoverflow.com/questions/8702474/updating-a-json-object-using-javascript

You have no idea how much your code helped me in my project. I need to download all clips with different combinations of parameters of a animation. Though I don’t really know JavaScript but I managed to do it by modifying your script a little bit. Doing it by hand was a pain. Thank you so much for this script.

Did anyone figure out how to download the animation with the inplace marker checked?

Add this before line 155:
gmsHashArray[0].inplace = true;

But also this script isn't working for me but the older version is: https://gist.github.com/gnuton/ec2c3c2097f7aeaea8bb7d1256e4b212

I get some errors when i add: gmsHashArray[0].inplace = true;

before - body: JSON.stringify(exportBody)
VM448:154 Uncaught SyntaxError: Unexpected token '['

after - body: JSON.stringify(exportBody)
VM451:155 Uncaught SyntaxError: Unexpected identifier

is there a way to also download appropriate gif with each animation? image id is in gms_hash, but I can't figure out the cors, cloudfront is refusing.
