Gawai Posted January 16, 2019 Share Posted January 16, 2019 I was wondering if anyone can help me with this one, Im very new to Fluids in Houdini and following an introduction to houdini fluids on digital tutors https://app.pluralsight.com/library/courses/introduction-fluid-simulations-houdini-2078/table-of-contents , in the chapter "Controlling the Fluid Source with Volumes" the instructor creates a fluid from an object by the Emit Particle fluid button. This was done in an earlier and the source is created with a Flid Source node that has controls for Velocity volumes and adds such things as a curl noise and vortex. However in H17 the source node is different and does not have these controls instead i read somewhere they were removed and its needed to add a noise attribute and volumer rasterizer but for some reason i cannot get the same outcome of giving random movement to the particles.. Im aware this sounds very beginnerish but any help with this would be highly appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
merlino Posted January 16, 2019 Share Posted January 16, 2019 The new FLIP Source will create 2 things: a surface and points. You can work on the points (for example using an attributeVOP) to modify their "v" (velocity) attribute with a noise or giving them the velocity you want. It think you'll have actually more control this way. Let me know if it works! Cheers! 1 Quote Link to comment Share on other sites More sharing options...

Gawai Posted January 23, 2019 Author Share Posted January 23, 2019 Thank you guys, ill test this out and let you know the results Quote Link to comment Share on other sites More sharing options...
mangenak Posted January 24, 2019 Share Posted January 24, 2019 Related to this thread, we used to see the streamer, for example the curl noise visualization, for each source using the Fluid Source node. In H17, how do you show the streamer for each source beside showing in the DOP network? Quote Link to comment Share on other sites More sharing options...
