Its been awhile since I played with the code and I’m away from my computer now so I’m just guessing here. I think I was talking about this line in the code:

self.pickerNode.setFromCollideMask(GeomNode.getDefaultCollideMask())

I was just playing around with the picking code. The picker can collide with geometry or a collision node. I was going to write up a follow up to this using tags but got side tracked.
