I was getting this thing where Unreal importing fbx files was giving me weird artefacts on meshes. I first thought that I was not setting the normals correctly in Blender so I was using Shade Auto Smooth and setting the Geometry Smoothing to FACE in FBX export settings

And i was making sure my meshes had some UVS.
BUT it seems unchecking all of these in the Unreal Static Mesh settings seems to fix it best – So that the mesh uses the imported normals
