Starshell illumination - or rather, lack thereof

[Ducimus]

Anyone have any idea of a shader file associated with the starshell illumination? I spent some time looking the associated dat files with starshells and its effects, and if theres any setting therein (particles.dat, materials.dat), that makes the illumnation.....illuminate, i didn't see it. Which leads me to believe im looking for a shader file.

Trouble is, theres so many to choose from.
