Creating an Ocean with Foam in Cycles Part 2: Materials and Rendering

Because the original video was too long to upload, I had to awkwardly split it up into two parts.
This video covers how to access the foam from inside Cycles, how to set up a realistic ocean shader, and a quick compositing setup at the end.

  5. Hi mate, brilliant tutorial. I used this as the basis of my offshore scene. I have one problem though:

    My boat has a wake leaving a trail of foam behind which works well
    My ocean has foam crests which work well

    However when the two interact it produces an obscenely bright foam making it unnatural. Is there a way to limit the maximum brightness? I've used the clamp feature to no avail and can't figure out a way of doing it!

  9. Great tutorial. I'm a 3ds Max person, but after seeing this I'm half tempted to start exploring Blender.
    If I'm gonna offer you critique like you asked, I would have loved to see the scene animated to finish off your tutorial. It's great to see what you're actually creating.

  12. This is great, but the foam is only rendering in preview not final render ?
    Edit: oddly I have fixed the issue. I swapped the Ambient occlusion out for a normal Diffuse shader and it rendered just fine. I then swapped back to the Occlusion and it works… odd !

  14. This is fantastic Blender DH! You really made it understable. Have you tried this while using HDR lighting? I am using Pro-lighting Skies by blenderguru, and when i put on the HDR lighting, everything looks black and weird. Do you have any idea what I could do?

  16. Awsome tutorial, I used a tall object in my scene so I had to put a second calmer ocean underneath to constrain the movement to, so it is a big object that's not being affected by every single surface wave, more like a ship or something instead of a bobber or bucket.

  24. @Blender HD, So far the tutorial is great, excellent job! I have only come across one problem that I could use some help on. Around 12:07 in the video, you play the animation for a little then pause it. Next you duplicated the attribute node, and use the dp_paintmap in it and link it to the mix shader. After that you switched over to rendered view and you clearly have a white circle around your monkey head, I do not, I've repeated these steps a few times, but nothing. I've followed the tutorial exact so far, but I can't figure out the problem, any ideas?? I'm running Blender 2.70

  28. Hi ! I tried this tutorial and all is okay, but when i make the render, there is no foam who follow my little bottle :/ Any idea?
    I guess the problem is juste a little thing that I don't click on but… i don't find it.

  30. @BlenderHD, Thanks for the tut, really fun stuff. I was wondering how to negotiate that ocean into a shape? I tried making a plane and using Shrinkwrap of the ocean to my pre modeled shape / plane but then the animation really gets flattened out and does not act as it should. Any thoughts on say creating that ocean into an "S" shape like a winding river?

  41. I think it would be helpful if you went through all your connection point on you nodes. in the end i had to pause and back track a lot in order to guess what your are connected. perhaps a screen shot would be sufficient

  42. I actually found a better way to make the foam texture – Instead of using an AO just use a diffuse shader but with a hue saturation and a RGB node behind. that way you get to controle the color of the foam and it wont glow in night scenes. Hope this helps someone.
