Sorry, Conjured, but that was removed a long time ago, those options are now useless in the latest versions (unless Lee forgot to mention that he put them back in)
I think someone told me that he took them out in favor of a "3D" explosion using particles.
I put those options back in for Ply's Mod, though, as meteorite pointed out. I made it so you can use the new method or the old method or both together.
You can, however, change the images that FPSC uses for it's hardcoded explosion, but this will change the way explosions appear for ALL flak.
The one and only,
Those who live in the past, are destined to insanity. Those who live only for the future, will be slaves to their ambitions.
Those who live in the moment... only they, are truly happy.
