CptWhite on the TBP internal forum mentioned a neat idea. Sunglares for exploding ships.
Basically, the idea is that when a ship explodes, in addition to its explosion and shockwaves, there is also a brief brightening in the screen if your looking directly at the vessel that has just gone up. Its been a common special effect since the days of Wing Commander.
I propose a $ExpGlare tag that specifies the level of glare. For instance $ExpGlare: 0.0 would do it FreeSpace 2 standard mode with no glare. $ExpGlare: 1.0 would fully white out the screen for that brief moment when the ship goes up. I suspect that something like 0.6 through 0.8 would do nicely for most large capital ships.
