Attached is a file for bone name mapping helpfull in the retargeting animation process
I usually rig my characters in Mixamo and use autorig script to convert it to a Biped
Then I export the character Biped from 3Ds max to Unreal Engine
After that I retarget animation from available assets which require bone mapping
MixamoMapping.txt Just rename file extension to .uasset
and put it in the character folder and in the retarget manger select rig humanoid and click load > MixamoMapping.uasset
where is the asset please?
