When I edit objects in edit mode it looks like that unless I changed view mode lit to unit. Whats wrong?
It seems like you might be missing a sun. Try to add a light-source to verify that this isn’t a graphical bug. You can also set the viewport to unlit instead of lit. This should make all assets visible to you.
Unlit fix it but the quality of the object and texture become unrealistic. I want to see exactly same like main tab.
