just opened a model i was working on last year in the new Blender 2.68 : in edit, the model’s showing up a dark royal blue instead of the normal grey it appear in Object mode. what’s happened? other objects that are part of the scene show correctly unless i switch to them and then when i move to Edit they turn blue as well.
I think you might have accidentally entered Weight paint mode (this happens if you hold Ctrl while pressing Tab to enter edit mode). Manually going back to object mode or pressing Ctrl + Tab should fix the problem in that case.
It’s also possible to show weights in edit mode, perhaps that option is on for some reason. Properties panel (N) -> mesh display -> overlays: show weights
Don’t get me wrong, it’s good to have the solution to such a problem documented in a post like yours It just looked to me like you thought you helped out wolfie138 but I’m sure that user tackled the problem long ago or gave up. Anyway, no offense intended.
