violalyu Posted November 14, 2016 Share Posted November 14, 2016 Hi Houdini friends, Sorry to bother you three times in a day... I'm still having issues with the simulation of leaves on the ground. I can't use POP for simulation because these leaves are in foreground and they'll hit the ground and stay eventually. However it seems wrangle torque or angular velocity on the packed points won't work, these leaves are not spinning around their own origin. Is there any way to fix this? I have the files attached that may better explain. Thanks a lot!!! Quote Link to comment Share on other sites More sharing options...

rbowden Posted November 14, 2016 Share Posted November 14, 2016 You can setup your rotational forces in sops and your rbd packed objects inherit this velocity as shown here:http://www.tokeru.com/cgwiki/index.php?title=HoudiniDops#RBD_and_packed_prims OR you can use pop nodes for creating spin, such as pop torque. You can put it in the third input on the rbd solver.http://forums.odforce.net/topic/18797-how-to-rotate-particles-in-houdini-13-dops/ 1 Quote Link to comment Share on other sites More sharing options...
