Try a plane/box very close to the camera with a mostly transparent
bozo texture. Should be fairly convincing, especially if you also
use a fog/media for murkiness

Hmm, yeah, I could try that. If I scale it a bit, and rotate it to get an
angle. Yeah, could work.
Hmmm.
Maybe I should have the storm coming in, then I don't have to have actual
rain in the picture. :/

I'm not sure that I don't like this version better, and my opinion is
ultimately the one that counts the most.

That looks really good although the sky is disgusting :-)
The photons look interesting although the structures seem quite large.
Nice to see someone else working on water photons too. Is it possible to
see some statistics?
The stones should probably be wet and darker near the water line. Another
nitpicking: the 'glow' seems very bright in relation to the sunlight.
Maybe it would be better to have a different object in the daylight
version (how about a model ship with remote control?)

I am planning to do something similar to my crackle tables with RMF for
illustration, but i did not yet have the time to work it out. There are
more parameters for RMF so things will be more difficult. Also it would
not be useful to only have only texture samples, because you can't easily
conclude how the corresponding isosurface looks like.

Media, and some partially transparent boxes closer up. I've thought
about the possibility of using isosurfaces, but never tried it...
Maybe create some meshes, each with a couple hundred or thousand
raindrops, and distribute many copies of them through the scene.

Well, yeah. But it wasn't a serious attempt. It came out nice enough for a
quickly thrown together thing.

Only used 20,000 photons, which isn't near enough for the size of the water
plane. There's a lot of speckling. What type of statistics did you want?

Yep. Haven't started the retexturing work yet. There is a 'water line',
but it's up higher, because it was for the mist rather than the water.
Looks a little strange in this instance.
When talking about the glow, did you mean the light from it, or the glows
themselves? The glows themselves aren't too bad, IMO, though they cast
perhaps too much light (you can still see their vague shadows), although,
depending on what he's throwing, that may be accurate.

You don't need the whole water plane, i elaborated this a bit in my
'outdoor water photons' experiments.
If only 20000 photons are distributed over the whole water the light
structures are probably fairly random and not related to the water
structure.

mostly render and photon times.

I meant the glows themselves. Imagine for example a fire in sunlight.
Even if it is very bright, it's brightness is hardly visible.
