Hi Robert,

I was looking of a solution that depends on camera. Because only the 
view/camera knows which object is hidden. The TraversalMask will do the trick 
then. I see also a CullMask, guess this is not good and it will not help with 
the picking issue.

My understanding the mask is a 32 bit value, this means I can only have a 
maximum 32 types of nodes to be shown/hidden because an AND operation is 
performed?


Thank you!

Cheers,
Catalin
