we have developed a new way of lighjting the spacecraft's interiors. Given the specifics of a very small windows, a very bright (or dark) exterior , a new lighting solution was needed to achieve photorealistic interiors.
now we compute the total light that enters throught the window , and compute the average number of bounces until it lights the entire cockpit. Sounds easy , but coding a shader that does that in a reasonable time is not that easy.
Cockpits look now something like this : (Please note the earth's luminosity
bathing the interior as it enters from the windows.
