: scale and depth

Scale
Here's the wireframe of the turtle island for scaling reference. If you look carefully at the feet there's a smudge in front of it - that's the forest and a flock of migratory birds (both very small.)

I also finished adding waterfalls all over the shell (maya hardware + software render particles.)





z-depth + y-depth passes
I've been testing out z-depth + y-depth render passes for use in compositing haze and lens blurring.
z-depth: mental ray depth buffer / y-depth: project a b&w ramp along the height of the tortoise. I need to take into account color and saturation differences between the near and far, high and low points in my framing (because of atmospheric effects.)
