Highlighter tool on nodes in model

[Seadna]

I'm trying something different. I certainly cannot figure out how to get the highlighter to highlight sub-nodes (so far).

Can I use the pick function instead? How can I use pick() when wearing an Oculus Rift? I can use it with my mouse on screen in the tutorial but when combined with my vizconnect configuration on Oculus I do not have a mouse pointer. Can i do this with an arrow similar to the laser pointer tool? How can this be implemented is there any example code?

As usual any help is much appreciated!
