Manipulate vertices in Line2Segments / Line2Node material in compute shader

I’m learning webGPU, and I am trying to animate vertices of a line geometry using compute shader logic and the beautiful feature of TSL!

I read a few topics here, in particular this one .
I set up everything properly and I can render lines.
I can’t animate them, nor using nodes and writing a custom Fn into the vertexNode, nor trying to mess up with geometry attributes.
Anyone can give me a hint on what’s the right way? I’m a bit lost.
If you need, I think you might use the codepen found in the thread I shared. I’m using the very same logic (with an update shader in the loop).
Thanks in advance! :frowning:
