shenandyi Posted September 10, 2013 Share Posted September 10, 2013 Hi everyone, The key parameter is "add Curl Noise" in "Fluid Source" Node, my custom vortex velocity field is made of Stamp Points from a volume of tube, so the velocity field is a tube shape, after adding curl noise, the field turns to a cube shape. My idea is making a Stamp Points density field (tube shape) to MASK the cube shape, but how to do it? Thanks! Quote Link to comment Share on other sites More sharing options...
shenandyi Posted September 11, 2013 Author Share Posted September 11, 2013 (edited) https://vimeo.com/74267658 finally, I made it in SOP, I think, maybe..., it has more control than MASK in volume source node welcome to exchange: vortexTEST.hip Edited September 11, 2013 by shenandyi Quote Link to comment Share on other sites More sharing options...
The Disasterpiece Posted February 25, 2017 Share Posted February 25, 2017 Too late to reply, but i recently figured out diving inside fluid source we can also add a mask to the 'volumevelocity1' node from the 'add noise scalar' node. works quite well Quote Link to comment Share on other sites More sharing options...
