I made an interest in this add-on yesterday or yesterday.
An add-on that allows you to enjoy SKETCH STYLE easily with one click. Very nice!
However, I don’t know if it was my misunderstanding, but I came here to report because I had a little strange experience today.
At present, this add-on sometimes “maintains” SKETCH STYLE material when the scene is “reverted” to “only one object with multiple materials”.
Fortunately, I didn’t save because I noticed an abnormality in the production.
I can’t reproduce it at the moment, but I’ll write it as soon as I have the information.
