I've been exporting mixamo characters to fbx then import into Blender. Each time I do the bones names get appended with a number. But in the middle. So like mixamorig1:lefthand, instead of mixamorig:lefthand. It seems to be different numbers for different imports.
I honestly don't know where to start to troubleshoot. I'm only using blender as a go between to export to glb and import into Godot.
Any hints? If I even had a clue where to start I could research from there.
