I have been searching online for over a day and trying a heap of different settings and fixes to solve this issue, but unfortunately my lack of understanding/knowledge about smoothing/normals must be giving me trouble. There seems to be plenty of posts about similar issues but nothing seems to be a fix for me. I have made a high poly sculpt of a large rock, followed by a retopo into lower poly ready for UE4. I then export the low poly from blender as an FBX with the model set to smooth shading
