Ive legally ripped some game sprites, with the permission from a community manager of the game, but the game uses shaders, usually when making games, developers add a dull layer on their sprites and then put them in the game files, and when its being processed in the game, a thing called "shaders" modifies each pixel removing the dull thing. this is incase no one steals it. so ive only been able to get the sprites
but they're dulled.
here, ive taken a screenshot of the game, and how it looks, and ive also overlayed the sprites next to it, the sprites are circle orbs, this "dull" effect is only used on low opacity/transparent assets in the game, such as these orbs for example, they're drawn low opacity on the inside to give it a "glass" or "crystal" sphere look.
