@Obscura I see....each RGB pixel of the 1d texture would retain the value of one NPC. Very clever. Now I just need to know how to make it dynamic so that I can, what, generate it directly in the engine....? I've seen the blueprint editor, I've used it to capture the PC's location, but I mostly copied from a tutorial, so I…
