Once completed the following steps you’ve effectively generated strands between the objects, though they won’t show up in a rendered image as you haven’t defined any size or shape yet. To do this simply get a Set Data node, right click on the Value Port of the node and choose Add Port After two times so you have three values. Open the PPG, enter self.Size as Reference and set the size to 0.1 or so. Enter self.Shape as Reference1 and choose Cylinder. To loft the shape along the strand rather than using individual shapes you’ll need to add one last attribute. Enter self.StrandDeform as Reference2, press enter and check the self.StrandDeform checkbox. Finally connect the Execute output of the Set Data node to the Port2 of the ICETree node.

Create the strands
While you’ve just defined the end position for the strands you can’t feed this information directly into Build Array node because the point positions derive from different component types (points vs. vertices). To fix this, get a Switch Context node and connect Multiply Vector by Matrix node to its Value input. Then connect the Result of the Switch Context to the End Value of the Build Array node. Get a Set Data node, enter self.StrandPosition as the Reference and connect the Result of the Build Array node to the input. Connect the Execute output of the Set Data node to the On Creation1 input of the Add Point node.
