Whitewater System | Omar Zarifi | H17 Masterclass

This masterclass covers features of the redesigned whitewater system in Houdini 17. It starts with an overview of the major changes to the system. The new workflow is then demonstrated by adding whitewater to several simple scenarios.

I'm a whitewater master now.

[@TheShadowCamel]

Great showcase!

[@tpiketm7045]

Bomb! I love you for what you are!

As shown on 21:18 that Omar created volume velocity for creating a vortex, so I was wondering that can't pop force be used instead of this?

[@mohammed.hamdaoui]

Just in time.

[@johnnyxue3097]

Would somebody explain clumping(density control) to me? The front part of masterclass says it gives repulsive forces to particles between each other so that they would be prevented from clumping. But the last example of water splash he used it to create clumping effect. So the question is what is density control doing on earth? Create clumping or prevent clumping?

It's a really cool

[@Achildsan]

Thanks

Great video, my only question is that you tweaked the incoming surface volume in order to get a nice leading edge. But when you convert the flip particles into surface polygons it also uses different filtering to get a nice polygonal surface. How would you get the whitewater surface volume to match the rendered polygonal flip surface after its been filtered? I've been struggling with my white water sim not matching the renderable surface of my flip sim. I keep running into the leading edge falling into the rendered mesh and just not lining up properly. Any ideas how to fix this?

You probably dont care but does any of you know a trick to log back into an instagram account..?
I was stupid lost my password. I love any tricks you can give me

[@camiloxander5028]

@Rayan Wade thanks for your reply. I got to the site thru google and im trying it out atm.
Seems to take quite some time so I will reply here later with my results.

[@camiloxander5028]

@Rayan Wade It worked and I now got access to my account again. I'm so happy!
Thanks so much, you really help me out :D

[@rayanwade8331]

@Camilo Xander Glad I could help =)

The whitewater shelf tool won't let me select my fluid no matter where I am in the node setup/viewport. It always ends up saying "No fluid object selected for whitewater" and I can't select it in the viewport. I am trying to use it on a small simple river like stream I made. Is the tool limited to specific cases? Any help would be appreciated. I'm on Houdini 18

[@JafarDashti]

Late to answer I guess but may help others also. first don't select anything or node, click on whitewater shelf then go to your water sim dop and select your flipobject, then move the curson over viewport and press enter.

Acceleration, curvature, vorticity

[@bbossin]

Around 18 min the presenter gets into practical examples.

[@bbossin]

Spoiler alert! Omar builds a killer vortex whirlpool and adds whitewater foam!

[@bbossin]

Omar applies the whitewater shelf tool at approx 28 min. Idk why I am narrating his vid.

[@sams_3d_stuff]

@@bbossin lol

[@avazevfx1564]

I really don't get why he just used a sphere as a whitewater emitter for that giant whirlpool, that would have looked sick with curvature/vorticity generation

[@barnabasch9525]

So the new whitewater looks much worse than the old? :D

[@kokoze]

Nahh :D they're just overdoing it for the presentation... I'm sure you can turn down the strenght of the cellular look
