Hi, I simulated the beach waves, turn off the GI the foam is realistic but after turn on the GI(also change foam scattering to ray-traced) ,the foam is become too few, how to get more foam in GI mode? Thanks.

How to render more Foam in GI ?

Hey,
In your renders looks like you have very little foam (I assume the foam is shaded as bubbles) and some mist rendered in fog mode.
In the first render where there is no GI, the water surface is darker and you can easily see the white foam and mist, but in the next render when there is GI the water is much brigher and it's getting difficult to see the foam.
If you wish to get more foam/mist there are a few things you can do.
1. You can increase the foam amount in the Foam rollout or adjust the Mist settings in the Splashes rollout and run the simulation again.
2. You can increase the Count Multiplier in the Particle shader options - this will spawn more particles without the need of simulating again.
3. You can adjust the color of the Particle shader for the foam/mist.
You can find more about the settings for the Foam here - https://docs.chaosgroup.com/display/PHX4MAX/Liquid+Foam
Here you can find about the Splash/Mist - https://docs.chaosgroup.com/display/...plash+%7C+Mist
And here is the page for the Particle shader - https://docs.chaosgroup.com/display/...er+%7C+PHXFoam
Hope this helps.Georgi Zhekov

Ah, when rendering in Point mode try to increase the Point radius and Point Alpha in the Particle shader options.
