I know there are a few ways of pulling location information from instances, but I am not familiar with them…
Basically, I’d like to create instances of objects between others, so that when the positions of the original instances change, the “in-between” instances automatically reposition to be centered.
For example, centering a cone between two cubes which are at different distances from each other.

you can set count to 3 to achieve exactly your setup
