Hey all! Working with an FBX model made in Blender, and getting these weird artifacts on the round section of the mesh in the Unreal viewport. When looking at the mesh in Modeling Mode, the round section looks fine though.

Left is the model selected in Modeling mode, which is smooth and what it should look closer to, and the right is what I’m seeing when its not selected.

Any idea what may be causing these weird vertical lines?

Make sure “recompute normal” is unticked in the import dialog.
Default import value changed in 5.5.
