I saw the Weta Digital extra on the extended version of Return of the King yesterday. Man, talk about compositing. That scene with the mumakil towards the end, it had tons of layers. Background, figures, lights, live actors, dust, smoke... Wheee! Just as a point of interest, Shelob had about 200 textures on her. BTW, that simple pine picture in my gallery has five layers. :-) Pity that the technique doesn't work completely in Bryce. We ain't got specular render as such.
