This video explains Adobe Mixamo's export options and how to import them into Unity. The video breaks down the export options including: key-frame reduction, frames-per-second, file type and skin. And has an "explain to me like I'm 5" explanation of interpolation.
I recently started a youtube channel during quarantine dedicated to Game Development. This is the first video in a beginner-friendly series dedicated to breaking down Unity's animation system.
As someone who found animation to be a foreign concept and unable to find any beginner tutorials that answered the questions I had, I decided to do the research myself.
I hope it helps someone out!
