Short description of error
sorry, can only give a case example.In my case, it was "No objects or images found to bake to". It took me several hours of working time to find out that I accidentally toggled renderability of the object off...
In this case, something like "warning: one or more of the selected objects is set non-renderable. Please check in the outliner" or so would help a lot,
A more typlical case: "warning: one or more vertices of the selected object xxx are not assigned to an image...." or so...
I know that this is not purely a bug, but as it's something similar, I think it is good to file a report. If not, I apologize.
Exact steps for others to reproduce the error
- unwrap and texture an object, make texture the active one
- switch the renderability off in outliner
- try to bake
