ieatvfx Posted November 18, 2014 Share Posted November 18, 2014 Hi All. Im currently learning Houdini and many tutorials are pre H13 using the old pop network which I can just about get my head around and find the correct nodes I want to use but very slowly. I now want to get up to speed of using the new pop network as this has improvements and will continue to be developed in later versions. Is there any tutorials on using the new pop network? Simple as creating rain. I can do using the old system with a emitter, few forces and a collision. With new pop network I'm lost as the collision node is no longer there. thanks.

With new pop network I'm lost as the collision node is no longer there. That's the beauty of the new pops, they just automatically collide with the other stuff in your sim. For example create a ground plane or a static object and off you go. Quote Link to comment Share on other sites More sharing options...
ieatvfx Posted November 18, 2014 Author Share Posted November 18, 2014 Ground plane works. Trying a static object with a path to a transformed grid (my own plane). Doesnt... I must be missing something obvious.. Quote Link to comment Share on other sites More sharing options...
eetu Posted November 18, 2014 Share Posted November 18, 2014 Static rbd objects use volume based collision detection by default, so a grid probably fails for that reason. Either switch the object dop to use surface collisions or use objects with volume. Also it's probably safer to wire things up the same way the shelf tools do, with rigid bodies connected to an rbd solver, and then the solvers merged together with a collision relationship..

ieatvfx Posted November 18, 2014 Author Share Posted November 18, 2014 Do you have an example.... kinda didn't understand that Quote Link to comment Share on other sites More sharing options...
pbarua Posted November 19, 2014 Share Posted November 19, 2014 Is there any tutorials on using the new pop network? I posted some links here: https://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=35168 Quote Link to comment Share on other sites More sharing options...
