Kangaroo works with particles, mainly… but with some goal object you can also insert meshes, lines, planes, etc…
The output of kangaroo is a mix of particles (points) , lines, planes, meshes, etc.
Some goal object need lines as input but act on pre-existing particles (like spring goal), so you won’t see the lines in the output.
The order of your outputs is the same as the input.
So, “show” is to actually show a geometry you might even NOT see in the kangaroo output.
As kangaroo load a tree of goal objects, usually Daniel Piker uses an Entwine, so you get the first branch of the outputs.
Do it like this:
