Gradient transparent material

I would like to make the glowing part (pink) get curved when I curve the mesh up.
I am making an audio visualization so that “bumped” part going upward will present a beat, but the beat won’t be seen because the texture won’t follow it.

thanks mate

No problem, feel free to mark as solution. :slight_smile:

But I don’t use volume, I use transparent shader. And the ground is flat. The transparent texture must adapt to the shape of the mesh and not the environment around it.
