Import skeletal mesh in ue4 from blender

Hi guys. i created a mesh in blender and then export in mixamo for create bones. but this configuration don’t like for my character,so i modify the weigth in blender and import in ue4 so give error in vertices modify. why? can i resolve this problem? thank you so much.

Hello there, it just simply means that some verticies of your mesh are not influenced by any bone. So all you really need to check is your skinning.

Thank you so much. i am importing the mesh without mannequin reference and then setting the humanoid for the animation.
