Mesh covered in shadow

Hi does anyone know what is causing this issue with my mesh, it has recently been covered in a dark shadow.

Hello, would you be able to provide some more context for this issue? Is this a mesh you made or from a marketplace? What does the rest of the scene look like? Are any other meshes having this problem? Are you using Nanite?

Have you checked that the materials for this object are set up correctly? Have you checked that the normals are correct?

From what I can see now, maybe the lighting needs some work. Here is a link for setting up lighting in UE5.
