I have some problems importing my blender model to UE4. I use autosmooth in Blender and have tried exporting the fbx using normal, face and edge smoothing. In Unreal, I have tried importing normals and tangents or just the normals, but nothing works. I can still see the side edges of the cylinder. Any help is appreciated!
How does a Blender Render look?
And does the model have UVs?
Also try apply another material
