Thanks for your curiosity, your time and your explanations.
This is a shot with path tracing bidir. Surprised. Some caustics are expected...
But the bubbles look realistic. Now I`m able to recognize they...
So the resolution for this pic will rest till the 4 version is out and I`ll give it a chance with photon mapping.
Raphael, can you explain the procedence of the meshes (air-water) in your test? Seems a little simulation. I like very much the behaviour of the water surface at the top (is only a mesh?).
Thanks for all.
The Water is just a cube surrounding the scene. The camera is inside.
The Cube has a Water material (Specular IOR 1.33) with some SSS and Absorption to get it a little bluish and a little foggy.
Attached to the air bubbles is a nother specular material this time with IOR 1 (for air) that also has a higher precedence then the water.
I also tried combining the mesh of the bubbles with that of the water and inverting the normals of the bubbles to the inside. It gives the same result then with a air material and a higher precedence.
The "waves" of the surface is just a mesh deformer and a highly subdivided mesh. I did not simulate anything.
I hope that answers the questions
You don´t dream in cryo.
