How to make a geometry follow the vertex from a carve node?

Hi! I'm creating a five second animation of fairy dust.

I drew a curve and used a carve node so that it creates a vertex that would follow along the curve. I also created a geometry that the particles can be emitted from. The generated particles are going to be animated in the pop curve force.

How can I make the geometry follow the motion path of the vertex from the carve node?

Is there a way I can substitute the vertex from the carve node with the geometry?

Sorry, no time to check .hip files but it sounds like you just need to use a Copy SOP to copy your object geometry onto the point? If you're geometry is in a different object, use an Object Merge SOP to bring it in.

You can bring in your carved curve point and then copy your particle sim on it using the Copy SOP. You should add the required attributes to the point on the curve to have proper control over the alignment of your particles as a whole.

Take a look at this node which does exactly that at the SOP level:

If you set the curve to be the Path Object, and Position to 1, that object will always be wherever your Carve's Second U ends.

Hope the hip file helps!
