first of all sorry for being noob.. in need to reference an attribute called $HITNUM which is in houdini 13 is called i@hitnum..
back then i use add attribute VOP to accomplish this..
but it seems that that node no longer exist inside the new POP VOP..
my question is how do you guys reference an attribute inside the popnet itself to use inside a POP VOP.. or any alternative ways.. thanks in advance ops:
You discovered that you need to enable the “Add Hit Attributes” toggle on the new POP Solver DOP. Collisions between RBD objects is the way to set things up for proper collision support. Note that the Collision Detect POP is used as it's name suggests: to detect a collision to change a state of the particles as bounces aren't supported with this POP. Again use RBD objects for collisions.
Enabling the “Add Hit Attributes” toggle on the POP Solver DOP creates a whole slew of attributes preceded with hit* that you can use directly in the POP Wrangle DOP however you see fit:
