nicoladanese 15 Posted January 15, 2019 hey! I'm trying to apply gas turbulence based on the velocity of my volume, what I want is turbulence only where the volume has some velocity, but I can't make it work although it seems pretty straightforward (see image attached) Share this post Link to post Share on other sites
ejr32123 69 Posted January 15, 2019 I think the control field needs to be a scalar field. You can use a gas match field and gas analysis to do this. I included a .hip file vel_turbulence.hip 1 Share this post Link to post Share on other sites
nicoladanese 15 Posted January 15, 2019 hey Evan works perfectly! thanks! Share this post Link to post Share on other sites
merlino 16 Posted January 15, 2019 If you're not using OpenCL you can also enable the asset modification, find the "forcescale" binding and set it as "vector" type. Then put a length node after it. This way you can leave "vel" as control field. 1 Share this post Link to post Share on other sites
