I think that's the effect of larger bits of transparent ice and not fluffy
diffuse snow.  At least that the impression I get, especially with the specular
reflections.

I wasn't quite able to envision an earlier comment about adding some emission,
but now I think that it does need to be in some way "brightened".

deeper sslt?
rgbt?
emission?
a smaller emissive or rgb 1 diffuse 1 snowball just beneath the surface?


Still, a very impressive texture  - it is looking REAL.

It is looking better and better! I think the new light-placement is also a very
good improvement. I like that frozen ice puddle too; I tried something like that
years ago but was never quite happy with the result.

I really like your initial render of the entire scene; so many nice textures and
lighting effects. Worth the extended render-time; it's a beauty.

That's great! Very well-done. I also like the fluffy appearance of your
snowman-- and the way its carrot nose tilts as the melting proceeds. A nice
touch.

Happy Holidays to All!

I currently use VirtualDub 2 FilterMod (which includes ffmpeg as its engine, I
believe.) It has a GUI, which I like. Even though old, it's still available...

https://codecpack.co/download/VirtualDub-FilterMod.html

It can output various modern (or old) file formats, with various types of
compression. It has lots of configurable choices too-- many of which I don't
understand or use, ha. But I'm always learning.

[I've never been able to understand the 'shellout' feature in POV-Ray for
Windows, or how to use it. I don't come from a programming background, so the
concept itself is kind of a mystery.]

If anyone is interested, here is what I am using for the material:

#declare Real_snowman_snow_texture3  = texture {
    pigment {
        granite
        color_map {
            [0.0 rgb <1.2, 1.2, 1.2>]
            [1.0 rgb <1.15, 1.15, 1.15>]
        }
        scale 0.5
    }
    finish {
        fresnel
        diffuse 0.7
        specular albedo 0.2
        roughness 0.001
        subsurface { translucency 0.5 }
    }
}

#declare Real_snowman_snow_material3 = material {
    texture {
        Real_snowman_snow_texture3
    }
    interior {
        ior 1.33
    }
}

The snowballs are isosurface spheres.  I use f_snoise3d at a scale to deform the
spheres, and the f_granite at a smaller scale to get the bumps that make the ice
crystals on the surface of the sphere.

Taking a lot of your suggestions into account, I give you the final rendering,
completed just in time to end 2021, (it took 4 1/2 days to render!)

Happy New Year to all, and I look forward to more POV-ing in 2022.
