How to do a neon light effect inside an object or be seen that way with blender 2.8? I have this scene in Blender where I am trying to have neon lights emit through an object. See the lights inside the object seeping through?

But i'm not sure if that is possible since the object I am trying to do it on already has a texture and an emission nodes.

I'm wondering if there is another way to make it appear like the first image.
My idea:
I thought of making a emission mask just for those spots within the sign and fixing the orginal emission layer in photoshop.
What do you think?
You can use another texture to mix color with your emission texture map:

See the Checker texture &quot;Add&quot; to the emission socket, make it light up as the checker go white. That node is Color→MixRGB in node editor.
Photoshop is another approach if you only want a quick prototype and keep thing simple.
