rotate flip pump source

Recommended Posts

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

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.

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
