Maybe not related, but an interior with fade_power 3?
fade_power 2 is realistic for light fading from a light_source through a 
volume.
Through some material, you should use fade_power 1 or fade_power 1001 to 
use exponential fading.
fade_power is unrealistic in any situation, unless you appen to live in 
a 4D+time world.
