When it's textured and put into the game, considering that most, perhaps not everyone has a low ambient light setting and no emissive light flags so ships appear darker, Shivan ships with the exception of their glowmaps aren't necessarily blinds-the-eyes bright as well, it's a small detail so adding all of that together it won't be seen much. It's just an uncessary detail, I mean the more detail the better but I'd like to be able to notice it too.
Again, NOTHING ABOUT ****ING PERFORMANCE. I don't want to hear anything else about it, I never mentioned performance in the first place.
