The mountains from that angle were done in World Machine with Flow maps exported to help the snow distribution. They weren't done in one pass but several, combined in Photoshop as the outline had to match a particular look and time was of the essence. Some views had all TG2 skies separated into layers; others a mix of different rendered skies + photo elements + paintwork to fulfill the brief. No magic bullets.

One particular view of the bear staring across the arctic landscape then engaging in conversation with the girl used a matte painting for the flat midground, some photo elements taken on location to enhance the overall look, a World Machine generated near background, then an alpine fractal for the distant mountains. The foreground snow that the bear sits on is mostly XSI and Mental Ray. The sky is completely TG2 with still renders separated into their respective cloud layers, and a slight drift added in XSI as a texture projection. The drifting shadows were generated using a LWO export of the scape to make them follow the topography.
