> Since mixamo is an AI tool

is it? as far as i know it just provides pre-made animations, which would in fact be infringing unless they have a very permissive license (Mesh2Motion has cc0 animations by quaternius so if one wishes to include animations then yeah)

(and there's the automatic rigging which could fall under "ai", but 1) it's been around since way before the genai trend and i don't believe it has changed much 2) if after only removing animations everything's fine then that's not it)

Yes. the animation and rigging tools are AI-based.

i dont think autorigging algorithms like that used in mixamo would be classed as generative ai at all. it was first released as part of fuse character generator in 2013, a good 6 or 7 years before the first papers about GANs were written and started being actually implemented. it's an algorithmic tool, but it's not based on stolen training data at all. it just compares a mesh to a pose and rigs a skeleton to points on the pose. even if you consider that "ai", i dont think there is any "scraped training data" that went into autorigging algorithms, which is the legal and ethical grounds concerning ai that actually matter in the context of licensing derivatives. that said, i don't think adobe grants carte blanche license to the animations that are used on mixamo after autorigging, so i still think it could be an issue with redistributing adobe's animations. as hecko mentioned, mesh2motion is a good alternative which would allow you to redistribute animations with no issue, as they are all openly licensed animations.

but anyways, i really really really like this model, it has a very nice n64 style. i hope to see more in this style, keep em coming!

the pinnochio library is the oldest autorigging method i know of ( https://github.com/pmolodo/Pinocchio ) it is entirely driven by algorithms. mixamo's earliest incarnations were a couple years later. i mean, we don't have the source code of mixamo to know exactly how it works, but the fundamental concept of autorigging and weighting a mesh to that rigged skeleton are probably similar and not driven by scraped data. again, we don't KNOW for sure cuz mixamo isn't open source. not knowing for sure how it works, i can see why you are concerned about the possibilities of it being tainted by the ai bogeyman. certainly i dont think one can redistribute mixamo animations unless they follow adobe's TOS (whatever they are)

That is relevant if that is what the modern version of Mixamo is using. You're talking about the version from 2013. Unless they've made no changes to it in 12 years, there needs to be some indication about the current modern version of it not using unethical training data. The information I'm seeing says the modern Mixamo uses "Machine Learning". I understand "algorithms" were sometimes referred to as "AI" back in the day, but I've never heard "machine learning" used to refer to standard alorithms. I suspect you're correct, but I would like to have solid information confirming this for the modern Mixamo. Also, is there information indicating it still uses Pinocchio library? 

yeah i dont know the extent of mixamo's whole setup. i just know that the basic process of autorigging and autoweighting a mesh to a target skeleton for use with another skeletal rig has been around for a long time and isnt "ai"

mixamo maybe is doing alot more than that, at any rate i dont think you can just redistribute mixamo animations willy nilly. it's moot in this instance since the submitter removed the animation, but its a thing to learn more about for future submissions and get some sort of firm answer on yay or nay on meshes rigged to the mixamo skeleton.

EDIT:

also to konserwa, please dont take any of this personally, your model is awesome and i really really hope to see more low poly n64 style stuff like this from you in the future.

Agreed on all points.
