Can't seem to fix Eyedropper shortcut For some reason, no matter what file I open, when I press E I get a contextual menu about the brush's Stroke Mode, but not the color picker/Eyedropper. I have been using the default Shortcuts that came with Blender 2.8.
Changing the menu shortcut to something else causes E to do nothing, even when I check to make sure that the Eyedropper is setup with it as its shortcut key.
Not sure about your problem... The shortcut for the eyedropper is S. To set the shortcut: Preferences > 3D View > Image Paint > Image Paint (Global) > Sample Color.
