I have tried for several days in Blender to take animations from Mixamo and put them onto MyMan's rigify rig generation from a "Mixamo Styled Human 5 Fingers" metarig. I get as far as having the correctly animated FBX rig from Mixamo in MyMan's Blender file, but cannot for the life of my get the fucking thing paired in any way. I've tried ExpyKit, I've tried Rokoko, I've exhausted every resource I could possibly think to use, including the now abysmally POOED searches of Google and YouTube, and cannot figure anything out. Any video I find usually skims over this part like it's One Click easy.
Is there either a VERY autismally detailed, preferably written, guide on how to do this process (tl;dr Put Mixamo Animation Onto Blender Man) as if it was explaining it to the world's biggest retard, or perhaps is an Anon capable of telling me just from this what I'm doing wrong in a sentence?
