Marvin,

Am I crazy, or can you not use the PickingLibrary on Rectangle and Grid objects? I've set pickable to true, so maybe something else is going on? My TriArray-based Shape3Ds work great, as do Lines.

I have no idea tbh. But have a look at the geometry pick test class, if it implements testing code for such geometries.

The grid class is meant to be used for shaders anyway, which eliminates picking.

I think all of the parent nodes also need to be pick enabled

Figured it out. I was passing in the wrong BranchGroup into my picker; didn't realize you could send in a list. Problem solved!

Thanks guys.
