my problem is that I made my character in fuse and exported it to mixamo but before putting it in unreal I corrected in blender the problem with the eyelashes, but now I get an error that the bones do not match even if I only modified the eyelashes.
Are you trying to import animations directly into Unreal from Mixamo on the same rig from Blender? If so, Blender has a different way of dealing with rigs. When you export the rig from Blender, don’t forget to turn off “add leaf bones”. This still might not work. My suggestion would be to get all of the animations into Blender and export them from the same rig as your character. I am just shooting in the dark here.
