A bit of a work-in-progress, but far enough along to show.  This took about
4-days to render without any camera blur, which I'd like to add at some point.

There are a few more ornaments/elements I'd like to add in for interest.  I'll
probably have to play with the lights a bit or it will never finish rendering
before the holidays are over... :-;

What a warm, inviting scene! The lighting is great already!

Merry Christmas,

Looking at the picture in detail, I was unhappy with the way the puddle melting
off of the snowman looked.  So, in true geek fashion, I looked up the theory
behind surface tension of water when puddling on a solid surface, and rewrote
the macro that generates the puddle to take all of that into account.

Here is a closeup test view of the snowman with the new puddle, with which I am
quite happy now.  I will probably have to update the scene to make the puddle
more obvious in the full scene, because it's kind of hard to notice now.

Of course, now I'm unhappy with the scarf, so I'll be working on that next...

Yep that's an excellent puddle. If you're going for a more realistic look I
would recommend altering the snow texture a little too, maybe bump up the
emission value. I've never been able to develop a talent for textures so I can't
offer better advice but experimenting with the settings may yield a more natural
appearance.

Kind regards,
Dave Blandston

I didn't comment on the snowman before, because I didn't know if you
wanted it to be real snow. But now that I see that it's melting, I have
a couple of suggestions.

First off, the diffuse value needs to be higher, close to 1.0.  And if
you are *not* using radiosity, the ambient value needs to be scaled up
proportionately.

Second, snow really needs SSLT.  Of course, this will slow down the
render even more.  If you prefer to finish rendering by February, you
can cheat by adding a bit of emission to the snow in lieu of SSLT; I
once abused the ambient keyword this way to get a subsurface effect on
some beach balls.  If you cheat in this manner, then you may have to
take the diffuse below 1.0 to compensate for the "glow."

Otherwise, the scene looks great!

Thanks for the suggestions.  I keep waffling on whether to make the snow more
realistic or not.  The scene is a bunch of ornaments, so the melting snowman is
meant to be a bit of humor, but I had also considered making him a real snowman
who just happens to have wandered into the scene.  I'll try some of your
suggestions as I can see other uses for having a good model for snow.

Here is my take on a melting snowman:

Nice!  I thought about doing an animation of my snowman melting, and having the
puddle grow as he does so.  However, it all renders so slowly that I'd have to
rent a big server farm to get all of the frames done in my lifetime...

Any particular tools you use to convert frames to movies?

A beautiful light!
