Hi,
I am creating a waterfall simulation too in Houdini 15, to integrate into a Matt painting, and I cant figure out how to get the spherical particles in the screen shot below, to become more foam like and not so geometric. They are part of the whitewater simulation and i've searched a lot online and asked people and gone through the nodes, but cant figure out how to fix it?
Is there maybe a way to create a material for just those particles and change it to a more foam like texture and consistency or smoke, or is there a better way to do it?
Your guys stuff looks amazing compared to mine atm :') I would really appreciate any help, as this is my first time using Houdini, and I am working to a fast approaching deadline for uni (less then 3 wks away
)!
Thanks!
PS I tried what you guys were discussing but I just cant seem to get anything to change with the perfect spheres, im very new to Houdini so please explain in a very basic way if you know a solution so I can follow haha

Sorry, I can take a closer look when I get home. To me you want the spheres for whitewater as really that's what it is, water broken down into small droplets. You can add the mist shelf tool with the whitewater droplets for a combined effect to get something like this below although be sure to have a lot of room on your hard drive for caching the sim. But I can help you better if you're still wanting to get rid of the spheres later tonight when I get to my PC as I'm still in a learning phase as well. For now try making the droplets smaller and maybe up the birth rate to produce more of them to get a better foam effect.

Thank you I think I already tried playing with as many settings as possible but nothing seemed to be effecting the spheres. I don't have Houdini at home, but I will post the file on here anyways and maybe you could take a look later on if that's ok? I am concerned my whole file might just be broken, because when I opened a new Houdini file and created a quick emitter and whitewater it seemed to work straight off the bat, a lot better. Not rendering spheres but more foam like looking
I will try what you suggested again and maybe adding the mist to if can get the whitewater working. I am currently caching out the base water simulation to bring it into a new file and add whitewater then, to see if it works. If I can get both base and whitewater working separately in the files, then I can just combine them in post.
There's only 2 tutors in the uni that know Houdini, and they aren't around over Easter to help really, so I'm just tryna figure it out on my own and over emailing them haha So greatly appreciate your help!

I looked at your file and there is quite a lot going on in there that is now unnecessary since Houdini 12. I dont have a mic to make a tutorial right now which I think would be the quickest and easiest thing to do, but I'm working on a basic file for whitewater with notes inside demonstrating each step. The key to making it look nice has a lot to do with scale using Particle Separation and particle Radius Scale on your flip fluid. From there add the whitewater shelf tool to your FLIP fluid then scale the sphere size for the whitewater adjusting the @pscale of the attribwrangle inside whitewater_import which is generated after using the whitewater shelf tool on your FLIP fluid.
So, instead of creating the time_shift setup to create the whitewater as is the method used in the tutorial, just use the whitewater shelf tool on the fluid, much easier. From there you can tweak your foam to get much better results.
I'll finish up this demo file tomorrow, almost done.
