cloudfx Posted November 7, 2011 Share Posted November 7, 2011 (edited) I have a spline of spring which have velocity like below. caculated v from it and made it to follow smoke emitter to have the vortex force continuesly. and using attribefromvolume sop to make v to vel so I can read them in sopvectorfield dop in smoke simulation. I got it correctly but it does not update it's position like I see in sop network in dop network. It just stay in 0,0,0 where I created the spline at the firsttime. I made the sop path of sopvectorfield path to be "set always" and gas calculate dop 's calculation to be add and "set always" as well. I dont know what I am missing to fetch the velocity of the spline to be updated every frame. Attached the hip file as well. Please let me know anyone familiar with this problem. qustion_sopvectorfield.hip Edited November 7, 2011 by cloudfx Quote Link to comment Share on other sites More sharing options...
Solitude Posted November 7, 2011 Share Posted November 7, 2011 Try setting the 'time' param to set always as well. ? Quote Link to comment Share on other sites More sharing options...
cloudfx Posted November 7, 2011 Author Share Posted November 7, 2011 Try setting the 'time' param to set always as well. ? That works.. had to make the volume box to be bigger as the spline's travel length though. Thanks a lot! Quote Link to comment Share on other sites More sharing options...
