Water in Houdini

Hello, guys!
How make Octane see water in Houdini?
After rendering one can see only pink picture.
What you need to do to the water to be seen?
I recently started learning Houdini...

If you see only pink object, the problem is that you have not assigned an Octane material to it. You need to build a Octane material using the Octane vopnet or any of the Octane materials HDAs, and set this material in the object.

The small tutorial available in the docs could help to start:

Thanks for the answer!)
With other objects everything is fine turns, but the water - no.
Everything is as it was pink, and remains ...

And there is an example, but with the water?

Can you attach your scene to test it here?

Well, the problem is that you are rendering both ocean objects, surface and interior. They are overlapped, and the interior one doesn't have a octane material assigned to it, so it is rendered pink.

If you disable the ocean_interior object, or you set a Octane material on it, all should work fine.

Yes, it works, thank you!
Only here there was another problem ... How to return the water its properties? (Waves, foam, etc.)

Now it's more like an ordinary box, filled with texture

You need to build your own Octane material to simulate the water. I suppose that an animated displacement map should help with the ocean surface. I know that people exports the displacement maps from the Houdini ocean toolkit as image sequences to later use them in Octane.
