Weird black lins and spots on my meshes

Hey i got some problem with my meshes or lighting, imk owkring on an assets pack and there is a weird problem with them
a picture-

Everything has aUV map so im not sure what is the problem

If you are talking about the faceted faces, that’s due to smoothing settings (normals)

If you mean the shadows underneath the things like the sprinkles, that’s due to that they are meshes on top of the surface and require very high resolution shadows for the mesh for the shadows to more accurately line up with the object casting it.

FIxed, thank you very much
