apply gas turbulence based on velocity

Recommended Posts

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)

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

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.
