I am having problems baking textures with Cycles in Blender and am getting pretty frustrated, even earlier today it was working fine, but now every texture I bake turns out solid black. I figured I had messed up my blend file somehow so I created a brand new one from scratch and the same thing is happening.
I have a single material on a simple object, it is UV unwrapped and the UV's are definitely pointing in the right direction. I have multiple area lamps in the scene and if I render the scene it all looks just as it should. I have an image texture I've created to render my bakes to and have added a texture node for that to my material. The texture has been selected there and there is a yellow highlight around the node so Blender knows which image texture I want to render to.
But, when I click bake with either combined or diffuse selected it takes about a minute, and every time leaves me with a black render. This is a very simple process that has worked for me in the past so I am quite frustrated that it just seems to have stopped working for some reason. Can anyone tell me what I might be doing wrong?
Thanks in advance.
