  • How to stop raising foam from jumping off water? and Foam being stuck underwater?

    I have couple questions here:

    1. what settings stops rising water jumping off water in any speed? but i still need the foam on top of the water. Now its jumping off like soda drink in the ocean.
    2. how can I dissolve foam that was created underwater? Now the foam is stuck underwater and hanging there forever. Rising doesn't help, because it looks like soda bubbles coming up inside the ocean.

    It should look like when object starts moving underwater, it creates a trail that disappears 1s-2s behind it and still creates a foam on top of the ocean when objects jump out.
    Basically something like simulating torpedo motion that needs to slowly shoot out of the water, but the foam behaves weird now.

    ref Images attached + settings images + some artifacts issues

    Hello,

    This definetely looks quite strange. Can you send over the scene through the Chaos Support form here - https://support.chaos.com/hc/en-us (there is a Contact Support at top right)?

    To make bubbles go faster to the top you need to increase the Rising speed in the Foam settings - once they reach the surface then they can pop and vanish, underwater bubbles will live forever.

    Thanks!
