Alfred_dupont Posted February 28, 2020 Share Posted February 28, 2020 (edited) Hello, I'm learning through this tutorial but since H17, Houdini has changed the FluidSource Node for the Pyro Source. As shown in this tutorial I tried to get the Normal direction from the geo source to be transferred to the particles created in the pyro source to create the velocity field, but I can't make it works, anyone good soul to help me, file attached.

Atom Posted February 28, 2020 Share Posted February 28, 2020 Shouldn't you be routing the result of the cross function to v, instead of N? The H18 nodes look for that attribute. Try to populate it. Quote Link to comment Share on other sites More sharing options...
