How to smooth OBJ or FBX?

[pinarer]

when I bring my 3d clothing into c4d and render with octane, ( I attached an image) ... like in this case, my pleats dont look smooth, it is like wavy,, first I merged with phong 180 tag, nothing changed, I imported as it is nothing neither, then tried fbx, still it didint work, looks like Riptide plug in is not around anymore, so how can I smooth it? any idea?

Can you post a screen shot of your model mesh wireframe? Quickshade with lines would be great!
