I tried all three import options while importing the asset, “calculate normals”, “import normals”, and “import normals and tangents.” However, none of them result in smooth faces.
Do you get this when you put a plain (V3) material on the mesh? If that looks ok then it may be a material issue. If it does still occur and you feel comfortable with it we are willing to look at your .uasset to see what may be going on. Thank you!
