CTZn will be great to serve you as tester when you come back. Meanwhile...

I'm here ready to help at no condition. Either what...

Hi.
Will be a good prize to see them larger and cleaner, just give me a days for three study positions (try to adapt the last one for a "bigger" machine and resolution (more octaves...)).
Thanks too bubs.

Well, this is atm the landscape. All about your shaders (look at the germinal part of the displacement... canyons again !! ). The third part of the equation (detail) is not tested... In the need of almost three cams to finetune and give a proper detail ...

From some time ago, this proposal looks very interesant:

Main proc:
Code:
def distance(vec3 ps, real scl, int oct) real:
let
octave = toFloat(oct + 1)
pw = pow(2, octave) / 2.0
pos = ps * (scl * pw * paramOctavesRatio())
Vo = voronoi3d(pos, paramDisorder())
in
dist(pos, Vo) / pw
wich allows to sum outputs like so
Code:
distance(pos, scale, 0)
+ distance(pos, scale, 1)
+ distance(pos, scale, 2)
+ distance(pos, scale, 3)
+ ...

If you can now define a little more the procedure (if fits for this) ... A lot of thanks in advanced.

1.7 Million of unique triangles (what a beautiful subdivision algorithm !!!). Excuses once again to the team...

Hi.
Since the pigs was near to be lost yesterday, here goes.
Thanks a lot.

P.D: choose your own resolution, camera setup, tonemapping... but the scene is delicated. Thanks again.

gracias por compartir

the shader you refer to is the sturdy rock.

Thanks for the strong demand (not super clean for the chromatic). Super clean for the next try, this is a metropolis test ...
So glad to hear you Oscar, thanks a lot.
CTZn will be great to serve you as tester when you come back. Meanwhile...

The most exciting part is that the pigs is about 4KB of weight.

Can u share IGS from last one ? i`d love to cook it at 10k

[yonosoy]

Hi.
Sure. The print version is unprintable, sorry to the possible interested.
This is the setup of the last day with some modifications in the landscape and a not so hard camera. Is an experimental version (a residual SSS in the clouds equation to capture some atmosphere effects inside the volume and metropolis with values 0.9 and 0.05).
In the believe that this one is possible to see in a higher resolution, since the supposed detail fbm has been corrected.
Thanks.

Here a 10100s/px rendering of the "High_mountain_13.2.pigs", after 4.45h on 3 x 4770k machines.
Sadly MLT isn't that strong on the long run, so the enhancements in the last hour(s) where quite subtle...

The IGI can be downloaded from here: https://dl.dropboxusercontent.com/u/693 ... n_13.2.igi

Damnit, I want a wallpaper size one. Why is it rendering so slowly?

[dcm]

I was rendering 5k res during night but it looked same as in moment when i run it.

[Zom-B]

Why is it rendering so slowly?

Atmospheric scattering is used here and some inhomogeneous SSS media (clouds) with some freaky procedural noise. This is painful for every Renderengine, if you find another one even capable of rendering such stuff

[OnoSendai]

Try it without MLT.

[Zom-B]

Here a quick 1h rendering with PT up to 630s/px in wallpaper scale (changed some camera aspects here):

[Oscar J]

Hey, that's not bad. Is it slowing down, or would it be clean overnight?

[Zom-B]

Hey, that's not bad. Is it slowing down, or would it be clean overnight?

PT shouldn't "slow down" over time just like MLT does. But I actually don't have free CPU-time here to render that, since I have some animations in the pipeline atm...
