Indigo Renderer Forum

At this moment is not implemented.
If you want to experiment use an external material.
In the phase function tag you must put:
<mie_cumulus/>
But this phase function is only for clouds or mist or haze... (vapour in general).

Is the lowest speed that I have experimented in the use with indigo.
Numbers don´t seems to be correct (clones per amount of polygons don´t fit) and I´m not sure if there is a problem with it but the test are all in this way.
The thing is that even if I don´t use the doubled sided thin material I have the same speed for the scene, and in the other and 730 millions of polygons are not enough for this dramatic speed. I don´t know at this point but I will continue experimenting ...

EDIT: numbers seems correct out of the plugin used to spread the surface and a clay render is a lot faster.

21h of process, 146k samples/second , 7177 samples/pixel.
Bidirectional path tracing. Maybe for the next test I use metropolis.

The interesting band color present in mie_cumulus.
I believed that are glories when I saw it time ago over clouds.
What kind of phisic behaviour is this?

Holy crap, that last one is amazing. The forest shot had better clouds in your first test render though, IMO.

Holy molly, how did you get those ring like waves of rainbow? Aperture diffraction?

Hi.
The first time I saw this effect was over the clouds. At the first time I though it is a glory.
It is described with mie_cumulus. Here two pics related with this optical phenomenon.
Seems almost an aproximation to this , but nobody knows about at the moment (awaiting for some words from Ono (maybe))...
I expect that it is not a bug!!

Wow.

Hi

Halloween approaches ....

Mulder...? Scully?!

Ono, you are awesome. Indigo just ROCKS.

Gorgious tests and renders.
I´m quite interested in reading this thread discovering the possibilityes of Indigo.
Keep on rocking!

Cheers,
Raphael

Awesome jobs, yonosoy !

Hi. Thanks to all. Specially agree with Polinalkrimizei (Ono, you are awesome. Indigo just ROCKS).
And specially thanks to silverwings; not a polished work but there are a lot little things of interest (and no few errors).

More over Iwill try some foam for this scene.
Tomorrow I will test if only 1000 samples/pixels divided in five pictures with different seeds and the help of neat video (Zom-B´s thread) could do a better work.
If it is possible to aleatory change the seed every X samples/pixel the problem with fireflies could be solved (because the firsts fireflies appears at some time of render). Once (so many time ago) I did a test with 20 seeds and the result was fine (but this is a tedius work; strat, stop, change in XML the seed, start.... and finally mix all of them). I assume that it is not possible to aleatory (or not) change the seed in the run...

EDIT:
not the best scene to test the seed´s denoising because of the amount of SSS needs "temperature" (time) to looks good! For other ocasion. In adition the picture is perfect in twice of the time...

I looked at some fog + light through trees today, and didn't see anything like these bands. they may be an artifact. Can you send me the scene?
Thanks.

The scene is 295mb. How can I send you this scene? And where?

Pack the whole scene in indigo GUI, rar it and use https://www.wetransfer.com for example.
