old school Posted June 16, 2012 Share Posted June 16, 2012 Solver SOP needs some geometry to work on. You only had the previous frame geometry feeding the display output. At frame 1, the previous frame has no geometry in it. That is the issue you are running in to. You can use a Switch SOP to switch between the first input and the previous frame with the switch expression $FF>1. solver_sop_fixed.hipnc Quote Link to comment Share on other sites More sharing options...
sanchoflat Posted June 16, 2012 Author Share Posted June 16, 2012 Tnx, but problem - i use this atrribute in group node in DOP. I want to control so activ/passiv piecies of my geometry Quote Link to comment Share on other sites More sharing options...
sadhu Posted June 18, 2012 Share Posted June 18, 2012 You can create two groups in dops, one with active value = 1 (name - bybullet)with condition - point("/obj/box/null2",$OBJID-1,"activ",0) and other with the active value = 0 (name - bystat) with condition point("/obj/box/null2",$OBJID-1,"activ",0)!= 1. Make rigid body solver to work only on bybullet group and static solver only onbystat group. OR Just create bybullet group, don't use static solver. Make gravity dop work only on bybullet group. solver_sop_fixed_01.hipnc Quote Link to comment Share on other sites More sharing options...
