Hello,

i've a POP Solver with particles and a Static Solver of a static object on which the particles should collide. Also i have a popCollisionDetect which writes the hit infos in the particle point attributes.

Allways when i put on the static solver there will no hit attributes be written.

How can i get these hit attributes when i you a Rigid Body Solver or a Static Solver?

Is where a way?

Thanks!

When you use Rigid Body Solver or a Static Solver, you get Impacts data. You can get hitnum only solving data by POPSolver. By involving other solvers you will always get Impacts which you can access using “dopnumrecords” expression function. Here hitnum = number of records.
In other words:
POPs are DOPs for other solvers, so Impacts data get created.

In your case collisions are not being solved by POPSolver. In fact it's solving by merge DOP.
