Full disclosure I'm new to 3D art so forgive me of some stupidity. I'm working on a normal map for a hand sculpt that I've done. I'm attempting to bake the high poly version of the sculpt into the normal for the low poly version. I'll screenshot the settings below. The high poly hand was imported as an fbx into the low poly scene. The low poly hand has been unwrapped. Any help would appreciative, even if it's just getting me to ask the right questions when trying to problem solve in blender.
Update: I've attempted to use a cage and no luck. I've also done the normal baking process a few times with basic shapes in a new scene, all without issue. Any thoughts?
