'''SDF ONLY works with monochromatic images such as decals and fonts.''' SDF takes the original texture as an input and creates a SDF version of that texture and saves it in an image format. SDF version no longer stores the pixel color intensity like normal images do, but instead stores the distance to nearest opposite color. For example, since monochromatic images only have black and white, for every white pixel, you look for the nearest black pixel and stores the distance between thetwo and vice versa.
