I've seen a few people talking about using https://www.mixamo.com/#/ in LDJam and was curious if this is considered a content generator or an asset library?

It seems it's basically a library of animations and some retargeting features to apply them to different characters. I think most people would agree making 3D animations like these is HUGELY time consuming and a major consideration in making any kind of 3D game during a jam. As such I see a tool like this as totally game changing for the kinds of projects one could consider.

I was just wondering for future jams what the feelings are on using this tool and if using this tool is considered the same as say an asset store animation pack?
