To view the original post, please click hereI was able to dye all of the bookcases that you mentioned with a furniture dye tub.Academic bookcases can be dyed, but not engraved.
Wooden bookcases can be engraved, but not dyed.
And the plain old, inexpensive wooden shelf can be engraved and dyed, but will always show empty.
I have submitted a problem report into the system regarding the inability to engrave the Academic Bookcase.
