Hi, I have set my ocean scene in the stage. I set the ocean volume, the ocean surface, the whitewater. Thanks to rebelway "Rendering houdini ocean in karma". I had it all.

But I wanted to add a foam particles (via ocean foam node). It works in mantra but it doesn´t show in karma.

Any idea? I guess something should be tweak, density maybe?

Hi. There was a bug fix in 19.0.492 which addressed built-in ocean shader failing to render foam particles in karma. If you're using an older build, please update to 19.0.492 or newer and confirm that it works.
