Is there an easier way to create this kind of effect:

Without having to worry about textures, as in procedural (I think) and the only information I pass is what lines to apply the glow to?
Or perhaps only apply the glow at the edge of a UV island?
Here’s an example of a more complicated mesh where all the lines are glowing, of course, I could spend more time with the textures, but I’m not that good. :’(

You can render a material as wireframe in the editor, but it’s one-pixel wide and you’d have to render both that and another shader underneath… not sure if that translates to a packaged game version either.
