Material looking dirty on mesh

I have imported a mesh from of one of my old projects to compare. Both meshes were prepared the same way for the UV’s using steamroller plugin for max, the only difference is I did not use a material normaliser on the new mesh

New Mesh

I have changed the material by using texture coordinates, is it possible to get rid of this dirty look? Or can someone explain to me why this is happening? Thankyou

Could you post the material setup?
