Smart Material is looking weird on Mesh

Hi,

i modeled a mesh in Blender and wanted to paint it so i imported that into substance Painter. After that i baked the mash maps(except id Map). But after the baking process the texture is looking weird. It has already a material after baking i guess? Also when i add a smart material it looks like the materia is just repeated and not scattered:

1st picture shows the mesh after baking and adding material

2nd image shows how the material should look on a mesh(from a video tutorial)

3rd image shows how the mesh looks after baking maps
