greenish one) and one that works with geometry (the black one).
You've probably selected the wrong one. (in general, black nodes
need to be connected to other black nodes)</p>
<p>The <em>type</em> of a node is quite important. NodeBox will try
to convert between types, but in this case the two nodes do
different things, even though their names are equal.</p>
<p>You can read more about types and type conversion on our
