The Wallpaper pack is a seperate upload (since i want this to stay in the 3d section!) you can get it here
[link]Fyi, i changed the quality in this rendering in MK2 to max, now you can see the blurred reflections and transparancy clearly, (note the upper right corner is a nice example)
Edit: Changed it to waterscapes, primarily water, after all, or innit?

What the title says
Took me a while to make this bubble shader

Aside that, it was flying around in my mind
8x100x100 Particles form the scene, 920k polygons (each bubble is unique and *very* slightly, individual (thanks to a nice deformer plugin) deformed
Every bubble is unique..
And i was bored

most excellently done.
XD, But its very nice.
Lol, thank you
Is the lighting at the top volumetric or added in PS?
Did you use a projection map for the lights?
I remember using volumetric lighting before but i couldnt figure out a way to have a (image based) attenuation map (on top of my projection map), well in 3ds anyway, so i had to use multiple lights
I then applied a noise shader to the volumetric effect and scaled it in Y axis (thats up/down for me .p)
Then i simply set the falloff to that i like it
Theres actually global illumination at work here (hence the long rendertimes) and its based on the background gradient.. but i'll admit, the end result of the lightrays is maybe a bit too.. uh.. "pointy"
Last thing was setting a light which only purpose was the specular effect at 100% brightness, and place it somehow so it looks good
this picture is mainly , or rather only the bubble shader at work, doesnt look like much was done with it, but its highly complex, a lot of fresnel effects at work here, in diffusion (in c4d thats different from color) transparancy, Illumination and Reflection i each assigned a custom fresnel effect and played around till it looked good
If theres interest i can post the tutorial for the shader, the scene is simple enough to copy .p
