I have tried to recreate an effect similar to this one (in the 3:30 minute) https://www.youtube.com/watch?v=iqMVl2F1d4A using blender's geometry nodes.
The basic shape is an extruded circle mesh with the geometry nodes modifier.
The idea was to animate the circle using some texture and bind this to the frame value. Other circles are just a repetitions of the same geometry and texture but offseted by a few frames. It basically works, but the problem comes when i want to add more circles - the node tree is just getting huge. Can anyone help to make it more efficient?
