I created a DOP network that groups the objects by time, so they drop one after another, however this cuts of at a certain point, I don't know why.

Strange. I could not figure it out. It is working fine with RBD solver but not with BULLET solver.
$F*0.5>$OBJID starts giving you the desired result with BULLET solver but any number below 0.5 is giving the starange result.

It's somehow the copy sop, all I have to do is change it from copying up with transfer accumulative to copying to a grid, and it's fixed. Very confusing indeed.

The Bullet Solver is putting the stationary objects to sleep. This can be fixed by turning off “Enable Sleeping” on the RBD Fractured Object's “Bullet Data” tab.
