Lootable Corpse Highlighting
This plugin adds power armor style highlighting to corpses with loot when you sneak with Scrapper perk (rank 1).
Now comes in a variety of flavors!
To change the color of the highlight browse to /data/textures/effects/gradients/ and replace CorpseHighlight.dds with the one desired.
If you already have the perk you might need to re-acquire it like so:
player.removeperk 65e65
player.addperk 65e65
