johnLIC Posted January 17, 2016 Share Posted January 17, 2016 I am trying to set initial velocities on some cubes that are copied onto a grid. I can't make it work. I am able to create a velocity attribute and put good values in it, but the sim does not want to use them. It's quite possible I'm making a simple mistake. I am including a simplified scene file that has a few notes in it. rbd_init_vel_v01.hipnc Quote Link to comment Share on other sites More sharing options...
rich_lord Posted January 17, 2016 Share Posted January 17, 2016 (edited) Hello John. DOPs are looking for the point velocity to be in an attribute called v. All I did in this hip was change velocity to v in the attrib promote SOP, then they fall at different speeds. (Also, the VEX version you have here isn't working because you left the v attribute on the primitive and never promoted it down to the points.) rbd_init_vel_v01_fix.hipnc Edited January 17, 2016 by rich_lord Quote Link to comment Share on other sites More sharing options...
johnLIC Posted January 17, 2016 Author Share Posted January 17, 2016 Thanks! I suspected it was the name of the variable! Quote Link to comment Share on other sites More sharing options...
