I am generating a Lsystem and then attaching a metaball to it, I can't get it right.

I need to smooth that, this is my setup.

Like tamte said, it should be smooth. When you middle-mouse-click on the convertmeta sop you see that it creates a point normal attribute N. Maybe it's a display driver related issue then ?
I just exported it as obj and got it into Unreal without any problems.
