harvsingh Posted July 19, 2019 Share Posted July 19, 2019 Hi as the title suggests, how can i rotate a flip pump? i can get the pump object to work, but as soon as i rotate it, the direction of the pump stays the same. im using an wrangle to drive the vel from the normals. i have a volume trail, and the normals are pointing in the correct direction. iv uploaded a hip file if any of u guys can help. it seems like it should work, but what am i missing. Relatively new into Houdini. Kind regards Harv PS H17.5 apprentice version 01 pump-rotate-test 03.hipnc 1 Quote Link to comment Share on other sites More sharing options...
Atom Posted July 19, 2019 Share Posted July 19, 2019 It is common practice to not animate DOP sources at the /obj level. I moved your spinning animation into the SOP level and cleared the /obj level animation. Also, you don't need that rest. It seems to be locking your vel source to frame #1.

harvsingh Posted July 19, 2019 Author Share Posted July 19, 2019 Hey Atom that's great , very much appreciated. im pretty new to houdini, what is the reasoning behind not animating at object level? i though that was where most animation gets done? kind regards Harv Quote Link to comment Share on other sites More sharing options...
