I am instancing a circle using Instance to Points. I have managed to get the two circles scaled differently using an Index node on the Scale input. But no matter how I manipulate the value, the distance between the curves stays the same.

How do I set this up so that I can just scale the outside curve? Ultimately I want to be able to set them pretty close together and then fill them using a Fill Curve modifier.

The multiply add node might be a good option. If you change the multiplier value of the node, it will change the radius of the outside circle as long as it has a positive value.

It may be that you have to realize the instances in order to use the fill curve node.
