thanaras Posted July 8, 2009 Share Posted July 8, 2009 Hello, I am wondering if its possible, when you have a particle based fluid to keyframe the value of the gas constant. What i want to do is to have a gas constant value of value 0 for example in the 1st frame and then in a later frame to have it 250. But it doesn;t work. If you also have other suggestions on how to have a particle based fluid in rest and then to make it have the internal forces enabled in a later frame, it would be really helpfull. Thanks.

anim Posted July 8, 2009 Share Posted July 8, 2009 you need to right-click your particle fluid solver node ancd choose Allow Editing of Contents then dive into the node find apply_pressure_forces node select it and in property pane set menu on the left of the Gas Constant parameter from Use Default to Set Allways you can use the same for Enable Pressure Force you can return up one level this way the gas constant(or any param you've set to Set Allways) will be set on every sim step so it will use your animated value Quote Link to comment Share on other sites More sharing options...
