Insane Jason! very very good shot!
Actualy, I'm stuck with a black screen when i render the cached particle bgeo whitewater(from the wave tank). I switched the “import_whitewater” node to “render only point” but nothing happens…??? am i missing something?
Looks pretty simple Joker, i'll investigate! Thanks a lot!

Ok looks like i'll keep finding solutions right after posting here and asking for help. Actually i think thoses flat shapes are particles blocked by the flip tank roof…. Arghhh! re-sim again… I'm still open for advices and tips!

A: Thanks a lot Jordan! that's helping me a lot. I tried to group by bounding box and add a delete node, it works good but if i have too much wave height some parts are going outside the bounding box and create holes. Maybe there is another way?
B: I have done a very basic simulation in order to test compositing. I'm very far from the whitewater i'm looking for but it's just for the test sake.
I'm having an issue, looks like whitewater underwater are included in the alpha and create these black shapes. i think i need to tweak more with the render settings.. (see attachement picture)

This is a more complex sequence test. The Collision object's animation is far from perfect i'll modify it for sure. The splash doesn't quite look cool at this point snif. Maybe you guyz are combining rise animation with force fields? I really need a more spectacular rise splash. I don't understand why i have those flat waves at the biggest velocity level, from my general experience it sounds like a substeps issue…??
Is it possible to create the whitewater(shelf) with a cached Particle_fluid instead of a FlipTank object?

I found it! By changing the shader to billowy smoke, reducing the voxel size, and the last secret information that i couldn't find anywere, is to reduce pointwrangle= @pscale and tweak from there.
Now i'll need to find how to render only the top of the flip simulation. I'm hugely open for informations guyz!

Hi guys.
Looks like the question never has been asked. I'm a kind of new in da “Houd” and i'm totally amazed by possibilities. I have a decent bunch of experience years using Maya and i can't believe how big the difference is.
That's said, my question is, please, how can i get a decent whitewater foam look?
By default, the material applied is the default spray shader but gives me that smoke look. (joined screenshot) and even reducing voxel size doesn't help me.
The documentation looks poor about that but maybe it's so obvious that it doesn't need more explanation?
For me the best references right now still are

I think the best solution to get near these looks is to render whitewater as particles instead of volume smoke. May i desperatly wish for some help around here?
