Blender 2.79 Cycles Render curve bevel

I am attempting to make something that looks like lightning by using the ivy addon, then animating the bevel factor. It looks very good in the 3d viewport when preview rendering, but when it is actually rendered, the emission of the material, or the curve at all, does not show up.

I could convert it to a mesh, but I want to keep the animation of the strike.

Is there a way to get the bevel material to show up on the Cycles render?

I don’t know about ivy addon (strange, it says it’s installed and activated but I can’t find a way to add its thing), but I’m rendering curves a lot without any issues except smoothing issues.
