This mod is purely optional, and True-Nukes will run fine without it.
This mod is a purely graphical add on for True-Nukes.
This is not a stand-alone mod, and serves no purpose other than to provide the 64MB image files for the animation used for a larger nuclear detonation. Using this will increase VRAM usage, which is not helpful in the middle of a nuclear detonation, and doesn't do that mush, as it can only just be seen.
These images are just an upscaled version of the graphics for the nuclear detonation. It is only used for the 1kt, the 15kt, and the 100kt, which need a really huge animation for the explosion.
This is again sourced entirely from MushroomCloud, and in turn from the explosion in UraniumPower.
