AmyEden Posted March 23, 2022 Share Posted March 23, 2022 Hi, I'm currently doing a sim of a rocket launch with a pyrosolver and pyrosource. The rocket is dissembling in the sky and I need the smoke trail to stop. The houdini 18 pyro solver doesn't have the frame range tab and when I tried to animate the density the sim just stops. The smoke is visible on frame 1 but not on frame 2, 3, etc.... Does anyone has an idea how I could solve this ? Thank you so much !! Quote Link to comment Share on other sites More sharing options...
kushaldas Posted March 23, 2022 Share Posted March 23, 2022 You should be able to keyframe the Source Scale parameter on your Volume Source down to zero inside your dopnet. Alternatively, you can mult down your density to 0 over time in SOPs pre-sim using either a wrangle or vopnet. Quote Link to comment Share on other sites More sharing options...
