I was just reading the blender manual on baking a normal map from a high res mesh. To do this, I need to unwrap my mesh, but I don’t understand why I have to map an image to it for bake to work.
It seems to me that you just unwrap it, hit bake, and it should generate you a normal map. On the contrary, it says “No image found to bake to”. But when I load a random image, it works.
Just wondering why we need an image, and whether that image should be anything in particular.
Can someone please clear that up for me?
Thanks in advance!
