Bezier curve-based mesh's front surface is not appearing I made a bouquet by blender 2.70 for The Sims 4, but the front surface is not appearing (even in the Blender). I made it with a Bezier Curve.

How can I make it show the front surface? I'm trying to make it again, but is there any way I can fix it?
In this version it could be one side surface only. In 2.81 go CURVE => 2D => FILL MODE: BOTH. If you don't won't to update the software convert it to mesh and create mirror etc.
