I hope you don't mind me putting this other issue in here, I know it's unrelated but I don't want to clutter up the forum.

I have one other issue with the material I have created. When I move a light over it using Shaderforge shaders, the lighting seems to step on and off on the main surface. If I use a standard Unity material, it is much smoother. I've made a video to show you:

I also tried making a very simple Shaderforge shader, linking up a colour, but it has the same effect.

Thanks for the very speedy reply! I'll look in to what I can do to hide it.
