I followed the guide here: How do I bake a texture using Cycles bake

I unwrapped my UV, created a new image, created an Image Texture node and selected my new image with that, and hit bake. I then receive the error in the title. Here is a screenshot of my view: enter image description here

I'm definitely doing something wrong, hopefully one of you can point out what that is.

    $\begingroup$ You have empty material slot maybe that's the problem? $\endgroup$ – Denis May 18 '15 at 21:55
  • $\begingroup$ That worked! Thanks Dennis, I appreciate the answer. You can go ahead and write one and I'll mark it. $\endgroup$ – Douglas Gaskell May 18 '15 at 22:05

For baking in cycles each material slot requires image texture in the node setup, and it looks like even if the material slot is empty. To fix the error, remove the empty material slot from the object.

  • $\begingroup$ Do you think this should be reported as a bug? $\endgroup$ – Ray Mairlot May 18 '15 at 22:20
  • $\begingroup$ @RayMairlot That's quite rare for experienced user to have something like that. I dont think that will be considered as a bug because logically that's how it supposed to work. $\endgroup$ – Denis May 18 '15 at 22:36

    $\begingroup$ I'm not a fan of the above comment. You shouldn't have had to hack your way through this issue and it's unclear messaging multiple times to be able to avoid it. Bake should either be more intelligent, or at least be a lot more clear with the error messaging. $\endgroup$ – Tyguy7 Aug 1 '19 at 23:10
