While using 2.8 in texture paint mode, the image editor is nearly unusable, because it displays an overlay of the entire UV map, regardless of material or masking.
I’m not even looking for fine grained control; I’d be happy to just turn off all UV overlaying.
The closest thing I’ve found to an answer is this:
But it seems to refer to 2.9x, and in my 2.8 image editor “View” menu, the only items are “Toolbar” and “Sidebar”.
I’ve also looked at all of the tabs in the side bar, including View and Tool->Display.
Am I missing something obvious? Any help would be very appreciated.
