Well here it is!Download -> http://filesmelt.com/dl/Explosion_Effect_revision_by_eRe4s3r.rar
This mod does the following things (and has 3 modified sprite animations)
Revises sprite effect Explosion\Large -> Adds glow, makes it fainter/shorter
Revises sprite effect Explosion\Large2 -> Adds glow, makes it stronger (than Large)
Revises sprite effect Explosion\Small -> Fainter, smaller and glow
These 3 effects work "together" - Please note, its not overglow nuclear effect style, but if you have thousands of ships dieing you can expect an "adequate" effect level that will make this event noticeable even in far zoom.
Below how it looks scrapping a fleet of
400 ships in CLOSEST zoom - notice that i did not change the grenade explosion (which is a really cool effect and looks pretty nifty as is without glow)
This time there are no Attachments anymore - its 8mb+
Install the folders inside the rar to here
AIWar\RuntimeData\Images\Explosion - make backups of Large, Large2, and Small.
