Volume displacement

Hi,

I'm new to houdini and I've been trying for several days now to achieve this effect with volume displacement, I throw a couple of noises and a volume sample inside  a volumevop, but the results I get are by no means similar to the one descriobed in the screenshot, so what am I missing?

Thank you,

Hey dunken, here it is:

- I added nodes under yours in the vop

- i made a similiar setup using vdb (on the right). It's often the best way to deal with volume (faster and lighter)

thank you boby, I'll experiment with your file, the 0 to 1 range limit for the sliders UI in houdini can be very deceiving, as you need to crank the amplitude up to 10 for the displacement to takes effect,

Amplitude is in world unit. As your sphere is 20m radius it needs a big amplitude to be effective. A smaller sphere would need less amplitude :)
