Line Trace aka Trim Paths in Materials

Doing a deeper dive into what makes a Line Trace effect similar to say something like the Trim Paths of After Effects though if folks want to see more of a true comparison I can try to break it down further. This covers the basics of the math than the functionality 1:1.
A few Tutorials how to author the texture in various programs:
Blender: • Blender Gradient Demo
Inkscape: • Blend tool in Inkscape...
Substance: helpx.adobe.co...
Illustrator use the "Apply gradient along stroke" option
You want to search "gradient along the path/stroke" in whatever software you are using to get the effect you want here
And huge shout out to Jan Kaluza jan.games who helped me in the first place giving me a material to work from so so long ago. I'm happy to say I've come a long way in understanding materials since then.

Hi, awesome content! doing it in After Effects is so simple that I couldn't imagine you need to do/think all of this

Haha imagine game engines are more a direct access to the graphic card ;) so it's not necessarily the most user friendly but what you can do is quite incredible and more than just after effects. But sadly that means math xD which I'm slowly getting better at but always learning.

Great tutorial and explanation, really helpful! Did you figure out how to stop the start and end points of the gradient map from glowing when the line trace is further along the gradient map? I've just followed your video and my material is looking great apart from the start and end points look a bit glitchy.

I would triple check the the texture and make sure there's no black or white near those areas, the bleeding I found was reduced by making a thicker glow line and a thinner crop, and also making sure it's exactly 0 and 1 at the edges of the glow layer
