Cool idea. Only there aren't Yeti in Narnia IIRC. I do remember invisible
footprints, but they weren't in snow. Maybe the witch made herself invisible?

Wow. Trees are very very nice.
Don't forget the lamppost.

yikes,
looks like a lot of the country around here, especialy the places I go
snomachining
(except the mountains are further away here) In other words: Realistic!
It never ceases to amaze me what you guys can acomplish.
Gary
P.s. Would you be willing to share some code for the trees and the snow? :-)

Hmm, I've been thinking of animating (just out of curiousity - I wanna see
what's over the nearest hill). Render time is pretty reasonable, so I'll see
what I can come up with.

Hey, well remembered! They were in Voyage of the Dawn Treader - one of the
islands had one-legged invisible gnomes. The queen didn't turn herself
invisible, but she did turn herself and her no. 1 dwarf into a rock and a tree
iirc.

Yeah - lighting is still very much WIP....

Good idea - thanks.

Hmm, well I just use a y slope, so I suspect that all the tips are covered - it
just leaves the shearer faces uncovered.

very nice Tom, but shouldn't the snow near the base of the tree be lower
than that in the open? (because the snow collecting on the branches.)

I'm working on it, I'm working on it. ;) - well actually, I was thinking more
that there should be a small indented cone at the base of each tree since, iirc,
you get some melting close to the trunk - I'm not sure how much general indent
there would be, what with drifting and so on.
