Here's a piece of two F-117 soaring through the clouds.

The idea started with the fascination of volumetric rendering of clouds, and how to do it without plugins. After many months of looking into the skies rather than where I stepped, I came up with a way to fake ray-marching by using directional ambients with attenuation, and with a projected z-depth for distance compensation.

The purpose of the shot is to make a cool Hollywood shot rather than making something totally real.
