No foam with PHX source

[cb_LLC]

Hi I just have 2 questions.
1. is PCG the best method for underwater dust spread and scene scale 3 ?

2. We enabled foam particle generation but we are not seeing them. We want them to be bubbles that going up after the rock impact. Only drag particles work

Thanks

Hey,

Any method that looks good is good What conservation you use is a matter of what dynamic you want to achieve. Smooth and symmetric are better for shockwave type of effects with mushrooms forming. PCG is the most symmetric mushroom type of conservation but can’t create shockwaves. Buffered just curls the fluid and can’t create shockwaves or mushrooms.

You have no foam because this is a Fire/Smoke simulator. Foam from the source works when you have Foam simulation enabled in your simulator and for this you need a liquid simulator. Sounds like you need two simulators on top of each other - one for the smoke and one for the bubbles.

Cheers!
