Hey Jay

Each team had their own way of lighting. nothing was set in stone. What we used on my team was:

1 IBL cut into two:
1 piece sky & one piece for the ground. This let us make fnie adjustment to the amount of sky contribution versus ground. These IBLs may or may not contain a sun, sometimes it was painted out and the spec contribution added back in through other lights

1 Spotlight acting as a sun giving hard shadowing. Gobos were used extensively in the outdoor and jungle environments. It's a subtle thing, especially on the outdoor shots but high level clouds moving through the sceen and blocking the sun etc really adds to the shots. It's most effective in the scenes where he gets his banshee i think. We also tended to backlight our shots to give the best asethetic effect. Any direct sunlight into the face was much harder to light and make look good. The jungles had the most gobo work to help get the dense feeling from the shafts of light etc.

we had a series of IBLs that we used as rims and fills. They were essentially one light shot in a studio and were different sizes of light. So you could use them for various things from eye kicks through to broad fills. Very useful.

very specific light sources like fires and missile trails were generally simple point lights or spotlights with simple animation / colour variations.

SSS and Indirect lighting were also used extensively.
