Mine solved. because there wasn't any file on extra folder call spotlight diffuse image i manually copy it on that folder.

Achilles moved it to the .xbt file where it should be but didn't change the path in the xmls.  Extras folder was just a temporary solution while trying out a few different diffuse images.

when I installed new updates I faced same problem like ''spineco'' , then i used old spotlight image ( The one which is Brighter ) and placed it on Extra folder, It worked .

Yep, that will fix it temporarily.
