logix1390 Posted August 6, 2019 Share Posted August 6, 2019 Hello, I am trying to use the attribute noise sop to add some noise to my velocity. My basic question is, how do I change the frequency ? The attribute noise only has options for the amplitude, element scale and element size. It does not provide the standard noise options like frequency and roughness. I know how to create my own custom velocity in a vop but I wanted to be able to use the attribute noise sop for this. I will attach my scene for anyone that wants to take a look. Thank you h17_src_vel_frequency.hip Quote Link to comment Share on other sites More sharing options...
anim Posted August 6, 2019 Share Posted August 6, 2019 element size or scale is the inverse of frequency, arguably more intuitive and if you use any Fractal Type, you'll see controls for roughness too you can also use Point Velocity SOP in Keep Incoming mode and Add Curl Noise Quote Link to comment Share on other sites More sharing options...
