Hi, the max picture size is 5.2MB and you can upload a max of 5 images.
I’m using blender 2.80, this setup worked for me: So Object → Shade Smooth, then under Normals check Autosmooth and set the angle to 180 (so you would mark any edge you want to be sharp manually). When Exporting the FBX under Geometry set Smooth to Edge and check Tangent Space (this only works with tris/quads you may have to apply a triangulate modifier to your mesh). Then when you import the mesh into unreal import the normals only and generate the rest.
