XRM Posted October 21, 2012 Share Posted October 21, 2012 Hi, Am very new to Houdini. I am a 3ds Max artist. I recently started working with Houdini. I was wondering how to transfer custom velocity into pyro sims. I've a particle simulation cached. I was trying to transfer its velocity to a pyro simulation. I tried the shelf source from object tool, turned off everything expect velocity and switched it to add mode. IT seems its not working. Am sure am doing something wrong. Can someone enlighten me a proper way to do it? Ranadeep Mandal FX Artist Makuta Effects Quote Link to comment Share on other sites More sharing options...
sanchoflat Posted October 21, 2012 Share Posted October 21, 2012 Hi, you can use Fluid source sop to compute velocity. Add this field in dop, using sop vector dop and apply this field to pyro. See gas calculate or gas Linear combination dop. Quote Link to comment Share on other sites More sharing options...
XRM Posted October 21, 2012 Author Share Posted October 21, 2012 @sanchoflat : Oh man, thanks. Actually was doing this same approach. After reading your reply, I came to know that my approach was exactly the same. Which means I did some mistake with parameters. Then I checked the flow thoroughly and found that the activation parameter of the source volume was default at 0.169. Thats why it was not working. Changing it to 1 makes it work. Thank you mate Ranadeep Mandal FX Artist Makuta Effects Quote Link to comment Share on other sites More sharing options...
