I'm new to blender so please bear in mind that I might be stupid with this. But I am making my first object in blender which is a cookie, and I am trying to bake the texture of it into an image, but it doesn't bake the whole texture, only two small parts of the objects colors. I have tried looking up a similar problem but I can't find anyone with the same. Also there is no preview of the object in the image before baking, so I can not see what is supposed to show a cookie, it's just black. I attached a photo of how it looks once it's baked. What I did was, as I've learned, to select the object in object mode, switch into edit mode and bake the texture into a new image. When I look at other people doing the exact same thing they do not have this problem. Please help!
