I made a Downsizing script with the help of bing chat, that replaces all images (all cells with trimming included) in a sprite and downsizes them based on the majority of pixels that make upp the smaller image. so if a 2x2 image with 3 red pixels and 1 blue goes trough this script with the downsize of 2, then the image will be replaced with a red pixel in the top left corner. in the case that two or more colors are the shared majority the top left one is chosen.
the colors have to be identical to be counted as the same. so 255, 0, 0, 255 and a 254, 0, 0, 255 pixel will be counted separate
I made it so that i could get better pixel art from 3d renders in blender.
