foam clumping

[squintnic]

hello
having an issue with a sim and foam (please ignore the artifacted fog thats another issue with a volume grid) - video attached

im using the ocean preset as a base and have 2 rocks rising and thrashing about in the water, im happy with the look but the foam seems to be out of sync with the water and falls very slowly and has an unusual motion.
is this something to do with the low (?) SPF of 3 or something to do with the Liquid like / affect liquid settings in Splash / Mist?

Thanks

Did a quick low-res resim with similar setting and remade the point shaders - so it looks like its my splash thats behaving weirdly - what parameters do I look at to address this? even with smaller size they act weird
foam seems ok to me

thanks

If it's the splash, then you have too high Air Drag. In case it's the foam - it's the Falling Speed: https://docs.chaosgroup.com/display/...e:FallingSpeed

You can check more quickly which group it is using the Preview rollout's particle preview - you can enable/disable the preview of the particle systems from there.

Cheers!
