How to apply Nanite on Skeletal Mesh

Hello all,

I am new to Unreal Engine, and I am facing some problems. I have a rig that I want to import into UE 5.4 but every time I import it as a Skeletal Mesh there appears to be some black spots around the mesh. On the other hand, when I import the rig as a Static Mesh and apply Nanite to it, all black spots disappear. My question is how do I apply Nanite to the Skeletal Mesh?

(Left is the Static Mesh with Nanite, Right is Skeletal Mesh without it)

The solution was simple. When I imported the rig, I imported it with a scale of 1, making the UVs have weird stretches. Once I imported it a little bit bigger, the black spots disappeared!
