One way: if you have Poser4, import the 4 'splatter' props and stretch them to shape. Hell, just import them anyway, you won't need Poser. I tried this on a WIP and it looked fair, and this was on the 'Tidal Wave' obp available somewhere. I've also used the same splatter in Poser for a goose landing on water, worked out nicely. I've only recently re-acquired Bryce(4) after 18 months without it, so I'm still boning back up on it. But ... make a cylinder (horizontal) and work with volumetrics or clouds to get the right 'mistiness.' This can be tucked into the curl of an upcoming wave for the 'pipe' effect of surfing. Haven't tried this one yet tho. And wind-blown spray, now you got me spinning! Someone MUST have a better way? ...
