Hey guys and gals! Been a while since I've posted. Anyways, I'm making a wallpaper, and I want to add water drops to my scene to try to make it look a little bit more interesting. I found a few tutorials on how to do it in Photoshop, but they looked like crap when I finished them. Can anyone suggest anything else? By-the-Way here is the render.

Rock On,
Geoff

Is this for a still render or animation?

For a render, I would go with HYPERNURBS!!!

Tweak a sphere using points, throw it into a hypernurb object and ajdust the weight toward the top edge to make it slightly shallow.

throw on a clear glass sla shader with refraction set to high.

create a cylindrical array with instances and adjust the final locations and scale independently.

You might also try using an HDRI lightsource. Works wonders on refractive glass!!!

Thanks but I can't seem to figure out how to do it. Is there any tutorials out there for this sort of stuff?

BTW...

Could someone tell me how to separate the light spectrum when passing through a glass-type material.

I'm sure I'm missing something obvious and I'll feel like an idiot when the answer is revealed!!!

Gracias~

search for "brent turboleax" or something in this forum I think you mean caustic aberations and he has a pretty good way to fake it. If i am not wrong about the light spectrum thing, you mean the different colors so they can be manipulated.

Also the thing that picture needs is more of an enviornment and less black the black and grey in those saturations are really hurting your pic.

"caustic aberations" was exactly what I'm looking for... thanks JIII

I think the correct--or at least another--name for it is "spectral diffusion".

the correct term is "Chromatic Aberration"

Actually the phenomenon is "dispersion" and chromatic aberration is a result of dispersion and a flawed lens system.

"Chromatic dispersion" would be the most correct term :)
