It's a bit dark, but somehow homey and looks like Christmas :)

In fact, it's beginning to look a LOT like Christmas! :)

PS I'd love to see this with a string of lights around the tree, rather 
than just the few points you have.

Render time = 3 hours * number of lights (or much worse)


The shadows and glows do look fantastic from the lights that are there 
though.  Area lights?

Yeah, each light source is a 16x16 area light. Given that the tree has 
hundreds of thousands of tiny needles - wait, just read the render 
stats! Look at the number of shadow rays, for crying out loud! o__O

By the way, the floor is actually more patchy than it looks here. JPEG 
compression and all. (Check out the render resolution; this image is 
scaled down.)

I did also try this with radiosity - but it makes absolutely no visible 
difference. (Well, given how puny the light sources are, the extra 
bounces don't contribute much.)

That is my plan. I plan to have a dozen or so lights covering the whole 
tree. (You know, so you can actually *see* it!)

However, finding the correct light source coordinates by hand is 
*extremely* tedious and slow. (Especially when it takes NINETY SECONDS 
just to parse the scene!)

No! Lies! It's an 8x8 area light... (That's 256 point lights, in case 
your maths isn't so hot.)

My math is not so hot. What is 256 point lights?

Over 4 BILLIONS!

As Christmass lights are geting smaller and smaller, actual point_lights should 
be "good enough", especialy if you have 100's of them. Just a few 12's should 
make the use of area_light mostly pointless. Don't forget to set fade_distance 
to a suitably small value.
If manual placement is to tedious, why not try some procedural placement, maybe 
integrated in the building of the branches. In real life, the lights are often 
placed between branches.
If the parceing gets to long, why not use a switch to turn off the needles while 
you place and test the lights?

There are 72 points to an inch or 28.35 points to a centimetre for you
continentals :-)

Great image Andrew, with a full set of lights it should be ready for next
year. :-(
