  Asteroids ring (Message 1 to 8 of 8)

Exoplanet with asteroids ring on the recently discovered Oren-Nayar galaxy.

The asteroids are meshes created with meshrelief.inc, just 8 different
ones, instanced randomly 60000 times. The texture uses the new
oren-nayar diffuse model, which looks slightly better than lambertian
for this kind of object.

The planet is just a sphere with a turbulent pigment and a scattering
interior media.

The stars are a mix of 2000 spiky objects and a background pigment.

I like it! Glad to see this Jaime!

I just posted a small comparison of Pluto using default diffuse with albedo and
the lommel-seeliger at clipka's binary.images thread.

What value did you use? I only used 0.6 and tried another using 0.8, nothing
done yet with this other diffuse model as seen in your picture.

I meant to say Thomas De Groot's binaries.images message thread showing the
"diffuse implementation", which you probably already know of.

When you have a new hammer, everything looks like a nail  ;-)

   Very subtle difference...

   Around 0.4, which is the pebbles value from here:

Ah, okay, thanks! I still haven't taken the little time needed to try more
renders yet to see what will change using very different numbers. I can't seem
to grasp what the other examples being shown are doing so I want to look for
changes in my already known renderings.
