hozan Posted March 18, 2014 Share Posted March 18, 2014 Hello, I'm going to add force after setting particle position in voppop. This is what I want to do 1,birth particle and aline deforming geo. in voppop I used get attribute node, to set particle position to deform geo. 2,add collision and make new group 3,add force to new particle group but not move any particle I attached hip file and screen shot Thanks, and sorry my bad English. vop_pop_test.hip Quote Link to comment Share on other sites More sharing options...
gui Posted March 18, 2014 Share Posted March 18, 2014 The problem is in the vop sop. Sice u are setting the point position explicitly, no other force can change the points position on top of that. So, one work around would be changing the velocity or acceleration. The group pop doesnt change anything, since the particles dont have justhit attribute. check the file... vop_pop_test.hip Quote Link to comment Share on other sites More sharing options...
