If you're using

LineRenderer.material = new Material (Shader.Find("#SHADERNAME"));

you will receive an error and the LineRenderer will not work correctly.

I solve the problem creating a material, assign a proper shader (I use shader -> Particles -> Additive), and, in the script, LineRenderer.material = Resources.Load ("#PATH TO YOUR MATERIAL") as Material.
